Qualität Audio-System für Reiseleiter & Drahtloses Führungssystem Fabrik

When many foreign customers purchase wireless audio guide devices, they are often deterred by the "complex operation" issue - tour guides have to spend half an hour teaching tourists how to use it, and multiple teams need to switch channels and repeatedly adjust settings. The instructions are all in Chinese and are difficult to understand. Even the power-on and frequency alignment process requires dedicated guidance. For scenic spots, museums, or enterprises, an audio guide device is a service tool, not a "trouble generator". Easy operation is the core necessity.   Ⅰ.Easy-to-operate wireless audio guide device, the core lies in these 3 key indicators   For foreign customers, "easy operation" is not just a slogan; it must be implemented in every usage aspect. A truly reliable brand must meet these 3 indicators; missing any one is not considered convenient.   1. Automatic frequency alignment and memory function, ready to use upon power-on   Whether it's tourists or staff, after receiving the equipment, it is best that they can get started without referring to the manual. The core is "automatic frequency alignment" - once the transmitter is powered on, the receiver does not need to manually adjust the channel, but automatically matches the signal; it also has a "channel memory" function, so the next time it is used, it can simply power on without repeating the settings, which is extremely important for multiple teams using it frequently.   2.Minimal functions, fewer buttons are better   Too many buttons will only increase the operation difficulty, especially when facing tourists from different countries, complex buttons will confuse everyone. A good audio guide device usually only has "power on/off" and "volume adjustment" as core buttons, and even an integrated design, with no extra interfaces, is easy for the elderly and children to operate.   3.Comprehensive service and no language barrier   Foreign customers are most concerned about "not being able to understand the manual", so the brand must provide multilingual manuals and operation videos; if there are any problems, there should be multilingual after-sales guidance, without being stuck due to language barriers.   4.Why does Yingmi become the top choice for easy operation? Design meets the needs   Yingmi's selection as the preferred brand for many domestic and foreign customers is mainly because it has "easy operation" deeply integrated into the product DNA. Every design is tailored to meet the needs of foreign customers.   Ⅱ.Automatic frequency alignment + memory function, ready to use upon power-on   Among Yingmi's popular models like K8 and R8, all are equipped with automatic frequency alignment technology. Once the transmitter is unlocked and powered on, the receiver only needs to be turned on to automatically match the corresponding channel, without the need for manual frequency adjustment - whether it's a team of dozens or hundreds of devices used in batches, it can save a lot of debugging time.   What's more considerate is the channel memory function, after the receiver is powered on, it will default to matching the last used channel, such as using channel 1 for a tour in the morning and then powering on again, it will still be channel 1, without the need for staff to repeatedly check. Many foreign scenic spots have reported that after using Yingmi, the team assembly time has been shortened by 10 minutes.   1.Minimal buttons + lightweight design, no learning curv   Yingmi fully understands the principle of "less is more", all devices adopt minimalist button design. For example, the E8 integrated audio guide device, the entire body only has one switch for power-on and volume adjustment, long press to power on, up and down to adjust the volume, even non-Chinese-speaking foreign tourists can operate by looking at the icons; the weight is only 16 grams, the integrated design is fashionable and compact, holding it is completely effortless.   The receiver of the K8 team explanation system is even more operation-friendly, it is non-in-the-ear earpiece design, once powered on, it can be listened to immediately, the only button is used to adjust the volume, tourists do not need to perform any other operations throughout the process, comfort and convenience are fully achieved.   2.Multi-language compatibility, no language communication barriers   Yingmi has long considered the language issue for foreign customers: not only provides English, French, German, Japanese, etc. operation manuals and video tutorials, but some high-end models also support multi-language interface switching, staff can switch to the corresponding language operation interface according to the tourists' needs, with one-click operation. More importantly, Yingmi's HM8.0 multilingual sharing platform can directly pre-install multilingual explanation content on the device. Tourists can switch to the language they are familiar with without any additional operations, making it particularly friendly for international tourists.   3.Simple batch management, saving staff's effort   For scenic spots and museums, batch management of the equipment is also part of the "simple operation". Yingmi's professional metal contact charging box can achieve integrated batch charging, storage, and disinfection. Staff do not need to plug in each device one by one. Just put the equipment in the charging box and they can see the charging status of each device clearly.   The charging box also has anti-theft function, suitable for batch management in scenic spots. Some models support batch frequency matching, and staff can set the channels in advance. Tourists can start using the device as soon as they get it, without having to debug each device one by one. There is no need for individual adjustment.   III. Choose the right model for different scenarios, making operation simple and more convenient   Different scenarios have different requirements for the audio guide devices, but "simple operation" is a unified standard. Based on the common scenarios of foreign customers, these Yingmi models can precisely adapt and have almost zero learning difficulty:   1. Multi-team reception in scenic spots/museums: Choose the K8 team explanation system   This is the "simplification king" for multi-team scenarios. The operation is extremely simple: After the transmitter is turned on, all receivers automatically synchronize frequencies, and tourists can listen as soon as they put on it; the channel memory function avoids repeated debugging, and staff only need to manage the transmitter and don't need to worry about the tourists' receivers.   It adopts a non-in-the-ear ear hook design, weighing only 22g, making it comfortable for tourists to wear and solving the hygiene problem; the communication distance exceeds 100 meters, and tourists can freely walk around in the scenic area without interruption of sound. Scenic spots like Suzhou Taihu Scenic Area and Guizhou Xiaoshi Ancient Town are all using this model, and they receive multiple international teams every day, with no operation complaints.   2.Small events/elite small groups: Choose the E8 all-in-one audio guide device   If you want to hold small events or temporary exhibitions, the E8 is the first choice. It is an all-in-one design, without any extra accessories, and can be used after turning on. The main speaker can be hung on the body, which is lightweight and stress-free; it supports dual-speaker function, and the two main speakers can switch without debugging the equipment, and can be switched with one click.   It weighs only 16 grams, is convenient to carry, and foreign customers have reported that "running it through multiple exhibitions, the operation has never gone wrong"; the sound quality is not muffled, and the SOC embedded digital noise reduction technology can filter out environmental noise, making the explanation sound clear and transparent.   3.Budget-limited/self-service visit: Choose the QR code audio guide system   If you want to completely eliminate the trouble of equipment operation, Yingmi's QR code audio guide system is perfect - there is no need to purchase any receivers, tourists can scan the QR code on the scenic spot/exhibit with their mobile phones to listen to the explanation, and even turning on and off is saved. The operation is extremely simple: tourists open WeChat or the scanning function of their mobile phones, aim at the QR code on the scenic spot/exhibit, and can hear the multilingual explanation, and also view pictures and videos; the explanation content is updated in real time, and the scenic spot doesn't need to manage the equipment, just update the background content. Small specialty museums and niche scenic spots use it, with extremely high cost-effectiveness and enhanced technological sense. Conclusion   For foreign customers, the feature of "easy operation" of the wireless guide device is not an additional advantage but a basic requirement. Yingmi achieves the lowest operation difficulty through automatic frequency matching, minimalist design, and multi-language compatibility. Combined with precise models suitable for different scenarios and comprehensive multilingual after-sales guidance, it has become a convenient choice for customers worldwide.   Whether in scenic spots, museums, enterprises, or exhibitions, choosing Yingmi can eliminate the trouble of operation - staff don't need to spend time teaching, tourists don't need to bother learning, and everyone can focus on the content of the explanation itself. This is the core meaning of "easy operation".   Product Model Target Scenarios Core Operation Highlights Key Advantages Yingmi K8 Team Explanation System Scenic spots/museums (multi-team reception) - Automatic frequency synchronization for all receivers after transmitter power-on.   - Channel memory avoids repeated debugging.   - Non-in-ear ear hook design (wear and listen immediately). - Lightweight (22g, comfortable + hygienic).   - Communication distance >100 meters (tourists move freely).   - Adopted by Suzhou Taihu Scenic Area, Guizhou Xiaoshi Ancient Town (no operation complaints).

Many foreign customers who purchase wireless audio guide devices are troubled by the fact that "the standard model is uncomfortable to use" - they can't find a suitable one for minority language explanations, and they can't add any small functions that fit their specific scenarios because no one can handle it. To be honest, for those who organize international exhibitions, manage scenic spots, or conduct enterprise visits, customization services are not just an added bonus, but a necessary item that truly makes the equipment easy to use.   Ⅰ.How good is the customization service? Just check these 3 points   Not all brands can provide good customization services. Many are just "showing off". For foreign customers, a truly reliable customization must meet these 3 hard requirements, and missing any one of them is not worth considering.   1. Multi-language customization: Can handle any language, with good sound quality   This is definitely the most important point for foreign customers. Good customization not only needs to cover mainstream languages like English and French, but also small minority languages like Hungarian and Thai. More importantly, the sound quality must be up to standard. It can't be a stiff "machine voice", and the pronunciation of the language needs to be accurately reproduced so that the audience can listen naturally.   2.Function customization: Add whatever you need, don't spend money on unnecessary functions   The requirements for different scenarios vary greatly: for exhibitions, it might be necessary to record the explanations in advance and plug in a device to play them; for enterprise visits, it might require the audience to be able to ask questions, so there needs to be a two-way communication function; for scenic spots, it is hoped that the tourists can hear the explanations wherever they go, and an automatic sensing module is needed. The customized equipment needs to be able to sense and speak automatically. Good customization services mean that whatever function you need can be added, and the unnecessary functions can be removed directly. You don't have to spend money on functions you don't need.   3.International compatibility + cycle: Easy customs clearance, no delay in use   If the customized equipment fails to pass certifications like EU CE or RoHS during customs clearance, it will be directly rejected. In addition, the customization cycle must be clearly stated, such as how long it will take to complete, and whether samples can be viewed to avoid delaying the project schedule in the end.   Ⅱ.Yingmi's customization service: Fully understands the needs of foreign customers   Yingmi has dealt with many global customers and has long been familiar with everyone's customization needs. Its customization is not just "making some changes randomly", but it can adapt to the needs of international customers in terms of language, appearance, functions, and certifications. That's why international museum forums, the Xiangkun Temple in Vientiane, Laos, and other customers have chosen it.   1. Multi-language customization: No limit, and can optimize sound quality   Yingmi has its own developed HM8.0 multi-language sharing platform. In a nutshell, there are no restrictions on language customization - mainstream languages like English and French can be pre-installed directly; for small minority languages, as long as you provide audio or text transcripts, they can be customized. The most thoughtful is that after customization, the sound quality will be specially adjusted based on the pronunciation characteristics of the language, such as the tone of Lao language and the final sound of Arabic, which can be reproduced very accurately, without a stiff machine-like feeling.   For example, the audio guide device customized for the Xiangkun Temple in Vientiane, Laos, not only has 6 languages including Lao, English, and Chinese, but also has its sound quality adjusted according to the local accent； the equipment used by the International Museum Forum directly supports 12 UN official languages for switching, and multiple country delegations use it smoothly.   2.Function customization: Add or remove as needed, without wasting money   Yingmi's function customization is very practical. It is completely based on your needs. For example, for exhibitions, if you don't want to repeatedly explain, just add an audio interface, and record the content in advance and plug it in to play； for enterprise visits, upgrade the equipment to the 008B two-way communication model, so that the audience can ask questions and the presenter can answer； for scenic spots, add an RFID positioning module, and when the tourists approach the scenic spot, it will automatically speak. Take the Z1 intelligent display and explanation system for example. Some customers wanted it for use in high-end exhibition halls. Yingmi then customized it with facial recognition and voice interaction functions - the camera can identify the user's age and gender, and push personalized explanations. Users can also directly ask questions through voice, such as "How long is the history of this exhibit?", and the device can automatically answer, which is particularly suitable for high-end scenarios.   3.International Adaptation + Cycle Guarantee: Hassle-Free Customs Clearance and Usage   Yingmi had already considered the customs clearance issues for foreign customers. All customized equipment retains the EU CE, RoHS certifications, as well as the Chinese CMA and CNAS test reports. During customs clearance, just present these documents and there's no need for additional hassle; the charging module is also globally compatible. Whether it's 220V in Europe or 110V in America, just plug it in and it can be used. There's no need to buy a converter.   The customization cycle is clearly stated: for simple customization, such as adding languages, it can be completed within 7-10 working days; for more complex customization, such as modifying functions or creating an exclusive appearance, the timeframes will be confirmed with you in advance; what's most reassuring is that samples can be tested for free. Once you're satisfied, you can start mass production without worrying about the final product not meeting expectations.   III. Select the Right Model for Different Scenarios and Make Customization Easier   Yingmi can be customized for the entire series, but based on the common scenarios of foreign customers, these two models have the best customization adaptability and are also more cost-effective:   1. Exhibitions/Corporate Visits: Choose the E8 integrated audio guide device   This is the customized "universal model" that can be customized according to needs. For example, if an exhibition requires pre-recorded content, an audio interface can be added; if a company needs multiple languages, corresponding languages can be pre-installed, and listeners can switch languages with a single click.   It weighs only 16 grams and has an integrated design that can be carried in a pocket, making it suitable for mobile explanations at exhibitions. It also has noise reduction function, so even if the exhibition venue is noisy, the explanation can be heard clearly. Many international exhibitions have customized this model.   2.Scenic Areas/Museums: Choose the 007B automatic sensing audio guide device   This is specially designed for cultural tourism scenarios. The customization space is particularly large: the appearance can be printed with the scenic area's iconic patterns, and the color can match the scenic area's environment; languages can be mainstream or niche, and they can all be installed, meeting the needs of tourists from different countries; in terms of functions, the sensing range can be customized to avoid tourists speaking before reaching the scenic spot, and a text and image synchronization function can also be added, displaying the scenic spot images during the explanation, providing a better experience.   It has a 2.8-inch color screen and can be customized with multiple language operation interfaces, even for elderly tourists, they can understand it. One charge can last 8-10 hours, sufficient for the entire day's reception at the scenic area. The Guizhou Geological Museum and the Henan Museum have customized this model.   IV. Additional Benefits: These Services Are Free After Customization   Yingmi's customization service is not just about making an exclusive device for you, but also offers many free benefits that can save a lot of trouble:   For example, if you want to update the explanation content later, whether adding languages or changing the explanation words, it can be remotely and free updated without re-customization; if you make a bulk purchase, you can customize an exclusive charging box with your logo, charging and storage in one step; if the equipment has a problem abroad, a 24-hour multilingual after-sales team can provide remote guidance, and if it can't be repaired, it can be sent back within 10 working days and repaired and sent back.   Conclusion   For foreign customers, choosing a wireless guide device with customization services means choosing "convenience" and "ease of use". Yingmi's customization services can precisely meet your needs in terms of language, appearance, and functions, and can also ensure smooth customs clearance and controllable cycle. You don't have to worry unnecessarily.   Whether you are organizing an exhibition, conducting enterprise visits, or operating scenic spots and museums, as long as there is a customization requirement, Yingmi can provide an appropriate solution. There is no need to worry about "which brand can offer customization services". The practical experience of many foreign customers has proved that Yingmi's customization services are reliable and practical. The customized equipment can truly solve your problems instead of causing trouble.   Evaluation Criteria Core Needs of Foreign Customers Yingmi's Performance Multi-language Customization Cover mainstream + minority languages; natural sound quality  - No language limits: Pre-install mainstream languages (English, French, etc.); customize minority languages with provided audio/text.   - Sound quality optimization: Adjusts based on language pronunciation characteristics (e.g., Lao tones, Arabic final sounds).

Once you are satisfied, we will produce it in bulk.   Q2: Will customizing the appearance affect the durability of the device? A2: Absolutely not. Yingmi has its own factory, and the logo is printed with wear-resistant materials. The color is also an environmentally friendly and wear-resistant paint. The body material hasn't changed, so the shock resistance and dustproof performance remain unaffected. Just use it normally.   Q3: Can the customized devices obtain international certifications after customization? A3: Yes. All customized devices retain the EU CE and RoHS certifications, and you will also receive the complete certification documents. The customs clearance is problem-free.

As an innovative enterprise, Yingmi Technology holds multiple core patents and technical certifications, and its strength is highly recognized.

When foreign customers purchase wireless guide devices, the biggest concern they have is that they might malfunction at critical moments - several teams explaining simultaneously would suddenly have interference and chaos; while wandering outdoors, the signal would drop and there would be no sound; after using for half a day, the device would run out of power and shut down, or even the equipment used daily would malfunction after just a few days. For scenic spots and museums, the stability of the guide device directly affects the visitor experience, and if it fails, it could even damage their reputation. After years of experience in this industry, I have seen too many cases where companies got into trouble due to unstable equipment. If we talk about brands that can truly stand firm on stability, Yingmi definitely deserves a place in the list. After 15 years of deep development, it has become the preferred choice for many customers around the world.   How to determine if a guide device is stable? Look at these three key points.   For foreign customers, "stability" is not just a slogan; it must be truly felt. A reliable guide device must meet these three requirements: strong anti-interference ability, no interference even when multiple teams use it together; long battery life, no need to recharge repeatedly throughout the day; durable material, not prone to damage when used every day. These three points are exactly Yingmi's strongest advantages.   Core 1: Super powerful anti-interference, no interference even when multiple teams are on the same stage   Whether it's several teams visiting simultaneously in scenic spots or multiple exhibition halls opening simultaneously in museums, interference is the most annoying problem. Yingmi has solved this pain point very well, relying on two core technologies: one is its own-developed SOC embedded integrated digital noise reduction technology, which can filter out crowd noise, wind noise, and other noises, even in noisy environments with many people, it can be heard clearly； the other is digital secondary frequency anti-interference technology, combined with a 200k ultra-small channel bandwidth, different teams can use their own channels without interference. Even if 20 teams are crowded in the same scenic spot, there will be no interference or mixed signals.   More importantly, Yingmi's guide devices use the 860MHz-870MHz high-frequency band, which is much more resistant to interference than ordinary low-frequency devices, and can achieve lossless sound transmission, with a maximum transmission distance of 280 meters. Whether it's the open scenic spot paths or the multi-walled museum exhibition halls, the signal can be fully covered, and there will be no "lose sound after walking two steps" embarrassment.   Core 2： Long battery life, no need to charge frequently throughout the day   For scenic spots and museums, charging dozens or hundreds of devices every day is very troublesome, and devices with poor battery life may even lose power halfway, causing operational delays. Yingmi is equipped with PMU safe intelligent lithium battery power management technology, not only has a long battery life, but also is explosion-proof and overcharge-proof, very safe. The battery life of different models has been precisely calculated, and it can fully withstand a full day of use, without the need to rush to recharge every day.   Core 3： Durable material, not prone to damage even with frequent use at high frequencies   Scenic spots and museums' guide devices are used hundreds of times every day, and if the material is not durable, the shell may crack, and the interface may loosen. Yingmi is the original manufacturer, with 4 automated SMT production lines, it strictly controls quality from chips to shells. It uses high-strength lightweight materials, which are both lightweight and shock-resistant. For example, the shell of the receiver has undergone several wear resistance tests, even if it is placed in a charging box and repeatedly plugged and unplugged every day, it will not peel off or deform; the interface has been designed with waterproof and dustproof functions, and can be used normally in outdoor scenic spots with small rain or dusty environments.   Why can Yingmi achieve "global recognition of stability"?   The stability of Yingmi is not a matter of luck, but is strictly controlled at every step from research and development, production to quality control. As the original manufacturer, it can precisely solve industry pain points, relying on its hard power.   Core Technology： Self-developed core technology, ensuring stability from the source. Yingmi holds a number of utility patents and software copyrights, and its core technologies are all developed independently. Unlike some small brands that rely on purchased technologies, they cannot promptly optimize when encountering problems. For instance, to solve the issue of unstable outdoor signals, the R&D team spent two years testing chips, and finally chose a high-quality chip with long lifespan, low power consumption, and strong anti-interference capabilities; for multilingual scenarios, they also developed the HM8.0 multilingual sharing platform, and when switching languages, there would be no situation of signal interruption or poor sound quality.   Global multi-scenario practical verification, stability speaks for itself   Whether it's user-friendly or not, practical experience shows the truth. Yingmi's products have been tested in various extreme scenarios worldwide: in the Xiangkun Temple scenic area in Vientiane, they can withstand the tropical environment with high temperature and high humidity; in the Taishan Dai Temple scenic area, they can meet the signal requirements for outdoor open spaces; at international museum high-level forums, they can ensure stable transmission for multilingual simultaneous interpretation; in the SCO meetings, they can guarantee zero malfunctions in high-level receptions. These challenging scenarios can all be handled, and they are more persuasive than any advertisement.   Different scenarios stable selection: These two Yingmi models are worth choosing without hesitation   Yingmi has several high-stability products for different scenarios. Foreign customers don't need to guess blindly; they can choose based on their own needs.   Scenic area/conference first choice: E8 team explanation system, stable as a mountain in multiple teams competing   E8 is Yingmi's star model, specially designed for multi-team and high-frequency usage scenarios, with full stability. It is an integrated design, weighing only 16 grams, and it hardly feels heavy when held in hand, yet it is equipped with a complete anti-interference technology - digital secondary frequency conversion + SOC noise reduction, and there are 200 channels available. Even if multiple teams use it in the scenic area simultaneously, each team locking their own dedicated channel, there will be no interference.   The battery life is also very powerful. The transmitter can last for 15 hours at a time, and the receiver can last for 8-10 hours, which is completely sufficient for the scenic area's full-day operation. The contact-type charging box is made of metal, safe and won't catch fire, and it also has ultraviolet disinfection function. It can charge 36 or 48 devices at once. Put the equipment in it at night and take it out the next day to use, it's very convenient. Its transmission distance can reach 200 meters. Even when tourists are scattered for taking photos and free activities, they can clearly hear the explanations from the tour guide, without any signal interruption.   Whether it's scenic area team reception, enterprise exhibition explanation, or large-scale international conferences' mobile simultaneous interpretation, E8 is reliable. Now, 5A scenic areas like Suzhou Taihu Lake and Jiangxi Longhu Mountain are all using this model.   Museum/exhibition first choice: C7 touch + induction guide machine, precise and stable in dense scenarios   In museums and exhibition halls, the exhibits are close together, and ordinary induction explanation machines are prone to triggering and interference. Yingmi C7 just solves this problem. It has two usage methods: when the exhibits are dense, gently touch the label beside the exhibit (NFC touch) with the guide machine to accurately play the explanation; when the exhibition hall is open, use the automatic induction mode, and it will automatically trigger when you approach the exhibit, flexible and stable.   C7 can store multiple explanations and supports multilingual customization. By default, it has 8 mainstream languages, and the signal is very stable when switching, without lag or audio interruption. It can last for 10 hours with one charge, and it will automatically remind when the battery is running low, so there's no need to worry about shutting down halfway; the shell is made of high-strength ABS material, resistant to drops and abrasion, and even if the tourists accidentally drop it on the ground, it won't easily break. The inductive labels used with it are made of long-life low-power chips, and one battery can last for 3 years, without frequent replacement, saving a lot of trouble.   FAQ   Q1: Can the Yingmi speaker pass the EU certification? Is it compliant for export to Europe? A1: Absolutely compliant! All products have passed the EU CE and RoHS certifications along with the China CMA and CNAS dual tests. It has been exported to various European countries for years, and there are no issues with customs clearance. Just buy with confidence.   Q2: Can the signal be stably covered in outdoor open scenic areas or multi-walled museums? A2: Definitely! Yingmi uses a high-frequency band design and digital anti-interference technology. The signal can travel up to 280 meters outdoors and penetrate multiple walls indoors. Whether it's an outdoor trail or a museum exhibition hall, there won't be any situation where the signal is lost.   Q3: Can multiple teams use it simultaneously? How many teams can it support without interference? A3: It can support up to 20 teams at the same time! The Yingmi speaker has 200 channels available for selection, plus the digital secondary frequency anti-interference technology. Each team can lock onto their own channel, and even if they are moving in the same area, there won't be any interference or signal mixing.   Q4: Is the equipment repairable when it breaks in a foreign country? A4: Very convenient! There is a 24-hour multilingual customer service available, including English, French, and German. It supports cross-border repair. After receiving the broken equipment, it will be repaired within 10 working days and sent back. If you need it urgently, you can also send a spare device first, without affecting operations.   Q5: How long is the equipment warranty? Is it prone to breaking when used every day? A5: The warranty policy is very generous! If there is a quality issue within 3 months, it will be replaced immediately. It is free to repair within 1 year.

When foreign customers purchase wireless audio guide devices, apart from core performance such as sound quality and interference resistance, "ease of carrying" is definitely a key requirement that cannot be ignored. Imagine this: tourists carrying heavy equipment while visiting scenic spots, the audio guide device hanging on the arm of the presenter running all day, and attendees carrying large-sized devices while moving through the venue - not only is it tiring, but it also affects the experience. A truly useful portable audio guide device is not just "light", but also needs to achieve "no discomfort during long wear, no occupation of space when storing, and no difficulty in carrying". Among many brands, Yingmi, a brand that has been deeply involved in the industry for 18 years, has taken "portability" to the extreme. Its two products have become the preferred portable choices for scenic spots, museums, and conferences worldwide.   Yingmi belongs to HEFEI HUMANTEK. CO., LTD., a national high-tech enterprise. It has long started foreign trade business, and its products have passed EU CE and RoHS certifications. They are exported to dozens of countries such as France, Germany, and Malaysia. It makes portable audio guide devices based on a core logic: portability cannot sacrifice performance, and it needs to achieve "lightness" and "ease of use" simultaneously. Whether it is team explanation or self-guided tour, there are styles that are lightweight, designed ingeniously, and convenient to carry, fully meeting the usage scenarios of foreign customers.   The key to portability: not only lightness, but also "easy to wear, durable, and not occupying space"   Many brands think that "portable = weight reduction", but this is a misconception. For foreign customers, the true "easy to carry" needs to meet three requirements: first, the weight should be light enough, without discomfort during long wear; second, the design should fit the human body, not causing discomfort when worn for a long time; third, the storage is convenient, the matching storage box is small and exquisite, and it can be carried in batches or stored privately without occupying space. Yingmi's portable products precisely hit these three points.   Core element 1: Light enough for easy holding and wearing   The basis of portability is "lightness", but to what extent is it appropriate? According to industry data, if the weight of the audio guide device is less than 30g, it is hardly felt when wearing; if it is less than 60g, there will be no drop sensation when holding or hanging around the neck. Most of Yingmi's products fall within this range, such as the team model weighing only 22g and the self-guided model weighing only 50g, even lighter than an ordinary headset. Whether it is hung on the ear by tourists or placed in the pocket by the presenter, it is completely stress-free.   Core element 2: Ergonomic design, not uncomfortable for long wear   Just being light is not enough; if the design is unreasonable, even the lightest will cause discomfort. Yingmi has specifically optimized the ergonomic design, such as the ear-hanging model using a non-in-the-ear design, which fits the curve of the earlobe, does not need to be inserted into the ear, and will not hurt the ears or neck even after long wear; the neck-hanging model uses a lightweight body and soft hanging rope, which adheres to the neck without irritating the skin, and does not fall off even when running or jumping, completely not affecting the visit or work.   Core element 3: Convenient storage, easy to carry in batches   For scenic spots and museums, carrying audio guide devices in batches is a big problem. Yingmi's matching storage box is small and exquisite, made of full aluminum alloy, not only lightweight but also precisely fits each device to avoid damage during transportation. For example, one storage box can hold 30 self-guided devices, but its volume is only 1/3 of an ordinary suitcase. Whether it is transported to the scenic spot or across countries, it saves a lot of space.   Yingmi: A powerhouse brand that takes "portability" to the extreme   Yingmi can convince foreign customers to choose it not only because of its portability, but also because of its strong capabilities behind it - 15 years of industry accumulation, its own production factory, full chain quality control, and a complete foreign trade service, making "portability" while adding a reliable touch.   Accurate qualifications, no worries about export   Yingmi is a national-level high-tech enterprise, possessing numerous utility model patents and software copyrights. It has also passed ISO9001, 4001 triple certification. All portable models of the interpreter have passed EU CE, RoHS certifications and China CMA, CNAS dual inspections. They can smoothly pass through customs when exported to any country in the world, without worrying about compliance issues.   Own factory, precisely controlling the details of portability   Yingmi invested in an SMT soldering factory as early as 2009, achieving full-chain autonomous control from R&D to production. For example, to reduce weight, it specially selects lightweight and high-strength materials, ensuring the durability of the body while minimizing the weight; to optimize the wearing experience, it repeatedly tests the arc of the ear hook and neck hook, ultimately determining the most ergonomic design. Only the own factory can precisely implement these details.   Experienced foreign trade services, with guaranteed after-sales   Yingmi has been engaged in foreign trade for over a decade and has fully understood the needs of foreign customers. Whether it is multilingual translation of product instructions or 24-hour multilingual customer service, it can be precisely matched; in terms of after-sales, it supports cross-border repair, and after receiving the faulty equipment, it can be repaired and sent back within 10 working days. Even if the equipment is abroad, there is no need to worry about the maintenance issue. Scene-based portable recommendation: Choose these two models, covering most needs   Yingmi has launched two ultra-portable interpreters for different scenarios. Whether it is for team receptions, independent travel visits, or business meetings, they can meet the needs. Foreign customers can directly choose based on their own scenarios.   Team meetings / scenic spot receptions preferred: K8 team interpretation system (22g, light enough to be almost imperceptible)   This is Yingmi's star portable model. The receiver weighs only 22g, approximately the weight of an A4 sheet of paper, featuring an in-ear-free integrated design. Worn on the ear, it does not press the earlobe at all, and even if the interpreter leads a group for a day, they will not feel ear pain. It fits in the pocket almost without taking up space, and it is convenient to take.   Although it is light, its performance is not compromised. It uses the 860Mhz-870Mhz high-frequency band, with extremely strong anti-interference capability, and multiple teams can explain simultaneously without interfering with each other; the communication distance exceeds 100 meters, and tourists can hear the explanation clearly even when scattered for taking photos; the battery life can last up to 7-8 hours, sufficient to support a full-day team reception. The charging box is made of metal material, compact and lightweight, capable of charging multiple devices at once, and it is fully integrated for storage and charging, especially suitable for use in scenic spots and enterprise exhibition halls in batches.   Its automatic frequency matching function is also very considerate. The receiver can automatically match the transmitter upon startup, without the need for manual channel adjustment. Even foreign customers who do not understand Chinese can easily operate it. Whether it is simultaneous interpretation at international conferences or team interpretation at scenic spots, using it is both portable and professional.   Free travel / museum preferred: M7 neck-mounted automatic sensing guide machine (50g, liberating hands)   If you are providing services to independent travelers or museum visitors, this neck-mounted guide machine is the most suitable. It weighs only 50g, with a thin neck strap design, which does not pinch when worn on the neck, and can free up hands. Tourists can take photos and hold souvenirs without any delay.   It adopts advanced RFID modulation technology. When reaching the corresponding scenic spot or exhibit, it can automatically play the explanation without any operation, completely avoiding manual clicking. It is particularly friendly to foreign tourists. It can store multiple explanations, support multiple language switching, and default covers 8 mainstream languages, and can be customized for niche languages. The battery life lasts up to 16 hours, allowing you to visit an entire day's scenic spots or museums without charging, reducing the hassle of carrying a charger. The outer frame of the dedicated storage box is made of all-aluminum material. It has built-in silicone grooves. When 30 guide machines are placed inside, they fit perfectly. After closing the box cover, it can reduce vibrations and protect the equipment from damage. Moreover, the storage box is small in size, making it convenient for storage and transportation in museums or scenic spots.   FAQ   Q1: Are the battery capacities of these two portable speakers sufficient? Do they require frequent charging? A1: Absolutely! The K8 receiver has a battery life of 7-8 hours, while the M7 can last up to 16 hours, both meeting the needs for an entire day's use. The accompanying charging cases support batch charging, so you can charge them once at night and use them fully the next day without frequent charging.   Q2: Will it be comfortable to wear for a long time? For example, will it hurt the ears or tighten the neck after wearing it all day? A2: It will be very comfortable! The K8 has a non-in-the-ear ear hook design, which fits the curve of the earlobe and won't hurt the ears; the M7 has a lightweight and thin neck strap design, with soft straps that won't tighten the neck. Both have been optimized for ergonomics, and many customers have reported that wearing them for a whole day doesn't cause any discomfort.   Q3: Is the accompanying storage box large? Is it convenient for batch transportation or storage? A3: The storage box is very compact! The storage box for M7 can hold 30 devices, and its volume is only 1/3 of an ordinary suitcase; the charging box for K8 is also compact and convenient for batch transportation, and there's no need to worry about taking up too much space during international transportation.   Q4: Can the products pass the EU certification? Is their use compliant for export to Europe? A4: Completely compliant! Both products have passed EU CE and RoHS certifications, as well as dual Chinese CMA and CNAS tests. They have been exported to regions such as Europe and Southeast Asia for many years, and have passed customs inspections without any issues.   Q5: If the equipment has problems abroad, is the after-sales repair convenient? A5: Very convenient! Yingmi provides 24-hour multilingual customer service, supporting communication in English, French, German, etc. The equipment supports international shipping for repair, and the faulty device will be repaired and sent back within 10 working days after receiving it. In emergency situations, backup equipment can also be provided. About us   HEFEI HUMANTEK.

When foreign customers purchase wireless presentation devices, they often make a mistake: they only focus on the performance of the main unit, completely neglecting the accessories. Once they use the equipment, they realize that they are missing a spare headset, the charging box is insufficient, or the sensor tag is broken and there's no replacement available; even more troublesome is that some accessories are incompatible with the main unit, and subsequent replenishment requires cross-border communication, which is time-consuming and energy-consuming. Whether in scenic spots or museums, if one wants to use the presentation device stably for a long time, the completeness of the accessories, their compatibility, and the convenience of replenishment are just as important as the performance of the main unit.   Yingmi is a brand of HEFEI HUMANTEK. CO., LTD., which is a national-level high-tech enterprise with its own SMT assembly factory. From the development and production of the main unit to the accessory supply, everything is controlled by itself. Unlike some small brands that produce the main unit themselves and purchase accessories from any factory, Yingmi's all accessories are developed and produced together with the main unit, fully compatible, without any awkwardness, and have passed EU CE and RoHS certifications, and go through customs clearance smoothly like the main unit. No matter if you buy a team presentation system, a self-service guide machine, or have special scene requirements, you can find the corresponding exclusive accessories, and no longer worry about "the main unit works well, but the accessories are hard to match".   Completeness of accessories does not mean a large quantity! Focus on the key points   For foreign customers, "complete accessories" is not about how many are there, but rather it must meet three requirements: First, it must be perfectly compatible with the main unit, and avoid compatibility issues when using; second, the material must be durable, as scenic spots and museums are used frequently, and replacing accessories is costly; third, the replenishment must be convenient, even if abroad, one can quickly receive the accessories. Yingmi's accessory system precisely hits these three core requirements.   Core accessories: Exclusive compatibility, stable and durable   Core accessories are the foundation for the normal use of the presentation device. Yingmi has exclusive core accessories for each model of the main unit, including charging, storage, and signal triggering, which can be fully equipped at once. For example, the M7C automatic sensing guide machine is equipped with a full-aluminum alloy dedicated storage box, which has a silicone groove, and 40 guide machines can fit perfectly. After closing the box cover, even if the device is shaken, it will not be damaged; there is also a contact-type charging box that can be powered by 220V electricity, with intelligent charging mode, which can both fast charge and protect the battery, and also has an option with ultraviolet disinfection, which is particularly hygienic for use in museums and scenic spots.   For example, the C7 touch + sensing guide machine is equipped with an inductive sensor tag that is particularly practical. It can support multiple signal numbers and uses a long-life low-power chip. Without pulling a wire for power supply, one battery can be used for 3 years, and it can be placed next to museum exhibits, and basically does not need to be taken care of; the E8 team presentation system's accessories are also thoughtful, the dedicated ear hook is ergonomically designed, not in-ear, and even after wearing for a long time, the ears will not hurt, and it is also hygienic; the charging base can charge multiple receivers at once, and the charging status is clearly visible, without having to guess whether it is fully charged.   Durable accessory parts: Regularly stocked consumables, as much as needed   Headphones and charging cables are consumables that tend to break over time. For foreign customers, the biggest concern is that the main unit is not broken, but the consumables are out of stock. Yingmi has already considered this, and all models of consumable accessories can be purchased separately, and bulk replenishment is also supported. For example, there are single-sided ear hooks and bilateral in-ear types, with clear sound quality and can block some environmental noise. Whether for teams or self-service use, they are suitable; there is also a portable USB charger, with a design of one charge for ten devices, powered by 220V electricity, which is particularly convenient for temporary power supply in scenic spots or as backup in enterprise exhibition halls. The charging cables, batteries, etc. are all produced by the same factory as the main unit, with the same quality. There will be no problems such as slow charging or poor battery durability.   Customized accessories: They can also meet special scenarios and precisely match the requirements.   Many foreign customers have special needs, and general accessories simply cannot meet them. Yingmi, as the original manufacturer, can customize accessories. This is particularly convenient. For example, when a large scenic area needs to transport equipment over long distances, a reinforced storage box can be customized, with an extra-thick aluminum frame and a shock-absorbing sponge inside. Even if it is transported across continents, the equipment will not be damaged.   The reliability of Yingmi's accessories: From research and development to after-sales service, there is no need to worry.   Foreign customers choose Yingmi's accessories not only because they are all good, but also because there is guarantee from research and development to after-sales service, which solves the worries of cross-border procurement.   Co-developed with the main unit, with full compatibility   Yingmi's accessories are not added later. They are developed and produced together with the main unit. For example, the charging interface and signal frequency of each presentation machine are precisely matched with the corresponding charging box and sensing label, and there will be no situations like "poor charging contact" or "no response when the sensing label is triggered". Like the contact-type charging box of the M7C guide machine, the charging contact is perfectly matched with the main unit, and the charging speed is 30% faster than general charging equipment, and it can avoid damaging the battery due to overcharging.   The quality is at the same standard as the main unit, and it has passed international certifications   Foreign customers have high requirements for product compliance. Yingmi's accessories, like the main unit, have passed EU CE, RoHS certifications, as well as dual Chinese CMA and CNAS tests. Whether exporting to Europe, America, or Asia, customs clearance is not a problem. The materials are also durable. For example, the aluminum storage box has undergone corrosion treatment, so it will not rust even when used in a seaside scenic area; the earphone cable is of high toughness and is not prone to breakage even after repeated pulling, and it can fully withstand the high-frequency use in scenic areas and museums.   Fast cross-border replenishment and timely after-sales response   Yingmi has accessory warehouses in several places around the world. When foreign customers need to replenish accessories later, they don't have to wait for shipment from China. They can just get the goods from the nearest warehouse. This is half the time compared to the industry average replenishment time. The after-sales service is more considerate. There is a 24-hour multilingual customer service online. Whether communicating in English, French, or German, there is no problem. If the accessories are damaged, cross-border repair is supported. After receiving the damaged accessories, they will be repaired and sent back within 10 working days. If you need to use them urgently, you can also send spare accessories first, without affecting normal operation.   Choose a package by scenario! Main unit + accessories for one-click assembly   Yingmi has already paired "main unit + accessories" packages for different scenarios. Foreign customers don't have to mix and match themselves. They can simply choose the package. It is convenient and efficient.   Tourist group in scenic areas: E8 team presentation system package   The package includes the E8 main unit, dedicated earphones, 48-position contact-type charging box (with UV disinfection option), backup batteries, and portable charger. The charging box can charge 48 receivers at once and can automatically disinfect. It is particularly convenient for batch management in scenic areas; the backup batteries can last for 10 hours, so there is no worry even if there is a long-term reception; the portable charger is small and can be used anytime by the tour guide when they are on the tour, even if it is far from the charging room.   VIP reception in enterprise exhibition halls: M7C guide machine customized package   The package includes the M7C main unit, a storage box with the brand logo, non-in-the-ear comfortable earphones, a small charging base, and waterproof sensing labels. The customized storage box has an exquisite appearance and can enhance the reception grade; the non-in-the-ear earphones are comfortable after wearing for a long time, and VIP customers will not feel uncomfortable; the small charging base is small and can be placed on the reception table, convenient for replenishing power at any time.   FAQ   Q1: Can Yingmi's accessories pass the EU certification? Are they compliant for export to Europe? A1: Absolutely compliant! All Yingmi accessories have passed the EU CE, RoHS certifications, as well as the CMA and CNAS tests for China. When exporting to Europe, America and other places, they pass customs as smoothly as the main unit. Now they are being exported in batches along with the main unit.   Q2: How long does it take for subsequent supplementary accessories to be shipped internationally? Can they be expedited? A2: Yingmi has several accessory warehouses globally. If shipping nearby, it takes 3-5 days for Europe and major countries in America; if it needs to be replenished from China, it usually takes 7-10 days. You can also choose expedited logistics, and it will arrive in 2-3 days. Specific details can be asked from the customer service.   Q3: Can the accessories of different models of Yingmi earphones be used interchangeably? For example, headphones and charging cables. A3: Some can be used interchangeably, such as USB charging cables and in-ear headphones. Most models can be used; however, core accessories like charging boxes and sensing labels are exclusive to specific models and need to be purchased corresponding to the model. When purchasing, clearly inform the customer service of the model, and you will be able to get the precisely compatible accessories.   Q4: How to handle the repair of damaged accessories? Do I need to send them along with the main unit for repair? A4: There's no need to send the damaged accessories along with the main unit! Just send the damaged accessories back, and 24-hour multilingual customer service will follow up throughout the process. For accessories that break within 3 months, they will be replaced free of charge. For those that break within one year, they will be repaired free of charge. Cross-border repair is supported, so you don't have to worry. About us   HEFEI HUMANTEK.
