When foreign customers choose a manufacturer of wireless audio guide devices, they are most afraid of falling into two traps: one is to choose small factories that only offer OEM services, with poor quality and problems occurring within half a year; the other is that the manufacturer does not understand international requirements and the products cannot adapt to local voltages or support minority languages, and there are also various certifications missing during customs clearance. In fact, it is not difficult to choose the right manufacturer. Just focus on 4 core points - whether there is independent R&D and production capability, whether all international certifications are complete, whether the product can adapt to multiple scenarios, and whether the after-sales service is satisfactory.
OEM factories do not have their own technologies, and their products are all copied. Later, they cannot customize languages or modify functions. Good manufacturers must have their own R&D teams and production facilities, controlling the entire process from design to production, so as to ensure stable product quality and be able to flexibly meet customized requirements.
Exporting products is the most troublesome for customs clearance. If there are missing certifications such as EU CE, RoHS, etc., the goods may be detained. Reliable manufacturers have already prepared a complete set of international certifications, and even can provide CMA and CNAS test reports. Once they have these, they can directly clear customs.
Different regions in the world have different voltage standards (220V in Europe, 110V in America), and the product must support a wide voltage range; there are also language requirements in minority languages, and it cannot only support mainstream languages such as English and French. In addition, anti-interference ability is also very crucial. At exhibitions and scenic spots, there are many people and noisy environments, and it must ensure clear and noise-free explanations without interference.
If equipment in the foreign country has problems, if the after-sales service cannot find anyone, the loss will be huge. Good manufacturers must have a 24-hour multilingual after-sales team that can provide remote guidance for repairs. If it is really difficult to repair, they can also provide spare parts or rapid repair.
Yingmi has been focusing on the audio guide device industry for a long time and is now a national-level high-tech enterprise and big data enterprise. It has been exporting to multiple regions in Europe, America, and Asia for many years, relying on its solid hard power.
Yingmi is not an OEM factory. It has its own R&D team, with annual R&D investment accounting for more than 15% of sales. It holds many utility model patents and software copyrights. The core H4 technology - SOC embedded noise reduction, PMU safe power management, ergonomic design, HM8.0 multilingual platform - are all independently developed, precisely solving industry pain points.
More importantly, in 2018, it invested in its own SMT surface mount assembly factory (Hefei Sichang Electronics) to achieve independent production of PCBA. From R&D design, component procurement, to production assembly and quality inspection, it controls the entire process itself, and each device must pass 5 strict tests, including high and low temperature, drop test, etc. The quality is much more stable than that of OEM factories.
Yingmi has already considered the customs clearance issues of foreign customers. All products have passed EU CE, RoHS certifications, as well as Chinese CMA and CNAS dual inspections. Whether exporting to Europe, America, or Southeast Asia, they can directly take the complete set of certification documents, without having to spend extra money on additional testing, saving a lot of trouble.
The charging module has also been made for international compatibility, supporting a wide voltage range (100V - 240V), and regardless of which voltage standard is used in the local area, it can be plugged in and used, without having to buy a converter.
Yingmi's product line is particularly comprehensive. Whether it is exhibitions, enterprise visits, or scenic spots, museums, etc., there will be suitable products to choose. And the details are fully in line with international customer needs: The team presentation system has models such as E8, R8, and 008B, supporting 200 independent channels. Even if multiple teams use it simultaneously, there will be no interference. The autonomous presentation system like i7 and 007B supports automatic sensing and can be customized for various minor languages to address the shortage of interpreters for minor languages. The zone presentation system MC200 is suitable for large venues and can achieve "sound starts when people arrive and stops when they leave", with no interference when switching between different areas.
The small language issues that foreign customers are most concerned about can be completely solved by Yingmi. Its HM8.0 multi-language sharing platform supports unlimited customization. Whether it's a minority language like Lao or Arabic, as long as you provide audio or text materials, it can be customized. It will also optimize the sound quality according to the pronunciation characteristics of the language and won't have a stiff machine-like feel.
For example, the self-service presentation device customized for the Xiangkun Temple in Vientiane, Laos, has 6 languages and the sound quality has been specially adjusted; the equipment used in the International Museum Forum directly supports 12 official languages of the United Nations for switching, and different country delegations use it smoothly.
Yingmi has many product models. Foreign customers don't need to worry. Select these 3 models according to the scenario and it's definitely correct. They are cost-effective and easy to use:
This is the "all-purpose model" for exhibitions and corporate visits. The integrated design weighs only 16 grams and is very lightweight, so it can be carried in your pocket. It uses SOC embedded integrated digital noise reduction technology. Even in a noisy exhibition venue, the presentation sound can be heard clearly.

It supports 200 independent channels, even if 100 teams are using it simultaneously, there will be no interference; the transmitter has a battery life of up to 15 hours, and the receiver has a battery life of 8-10 hours, and it's fine for high-intensity use throughout the day. It can also be printed with your brand logo and customized in color to match the brand style.
Designed specifically for cultural and tourism scenarios, the ear-mounted integrated machine is very lightweight and won't hurt your ears even after wearing for a long time. It uses RFID intelligent positioning technology, with precise sensing distance. When tourists approach the scenic spot, it automatically plays the presentation without manual operation.
It can store 9,999 segments of presentation words, supports multiple language switching, and can automatically remember the last used language; it can last for 8-10 hours with a single charge. The appearance can be customized with the distinctive pattern of the scenic area, and it fits well with the scenic environment. The Guizhou Geological Museum and the Henan Museum are both using it.

Suitable for large venues and conference centers, it uses LD high-precision positioning technology, combined with RFID, infrared, and WiFi three positioning methods. The zone switching is particularly precise. When a presenter leads a team into a certain area, the presentation automatically starts, and it automatically stops when they leave. The sound transitions smoothly between different areas without any noise.
It can also pre-store audio content to assist the presenter in presenting, and it can connect to background music and emergency broadcasts. The functions are particularly comprehensive. The Guiyang High-tech Zone City Exhibition Hall uses it to receive provincial leaders.
