Many foreign customers who purchase wireless audio guide devices often struggle with a question: Should they choose the brand or the manufacturer? In fact, for bulk purchasers, choosing a reliable manufacturer is much more reliable than simply looking at the brand - a reliable manufacturer can ensure timely supply, no quality issues, flexible customization, and even handle export customs clearance and after-sales maintenance for you.
When foreign customers choose wireless audio guide device manufacturers, they don't need to compare one by one, just focus on these 4 criteria, and you can quickly find a reliable partner.
Truly reliable manufacturers will never outsource assembly. For example, the important part of the audio guide - the PCBA board, if it all has to be bought from outside, not only won't the output keep up, but the quality won't be fully controlled. Good manufacturers will build their own production lines, and even invest money to build factories, taking every step of production in their own hands from the source.
This point is a must-have for foreign customers. Manufacturers need to be clear about the rules of overseas markets. For example, when exporting to Europe, CE safety certification and RoHS environmental certification must be complete; they also need to support multiple languages and be compatible with different countries' voltages. If these basic requirements can't be met, subsequent customs clearance will be stuck, and when using, the voltage won't match, and the trouble will be huge.
Wireless audio guide devices are mostly used in scenic spots and museums, and the environment is complex, so durability is very important. Good manufacturers have a strict quality control process, and every device before leaving the factory needs to be repeatedly tested; they also have their own core technologies that can solve practical problems such as noise reduction, anti-interference, and battery life. Otherwise, the device will break down after using for half a year, which is very annoying.
If the equipment breaks down abroad, if the after-sales service can't be found, the loss will be huge. Reliable manufacturers can provide comprehensive overseas services, such as remote equipment repair guidance, coordinating cross-border repairs, and even free shipping of samples for you to test, so that you don't have to worry about anything after buying.
Yingmi can become the first choice for overseas customers, in a nutshell, it is because these four standards have been fully met. As a national-level high-tech enterprise and big data enterprise, its strength and reputation have authoritative backing, there is no need to be afraid of getting into trouble.
Yingmi has long invested money to build its own SMT assembly factory - Hefei Sichang Electronics, completely getting rid of reliance on outsourcing. Now there are 4 automated SMT production lines, equipped with fully automatic printing machines and AOI optical detection equipment, the most core PCBA board of the audio guide is produced and tested entirely by itself.
The advantage of this fully autonomous production is obvious: production capacity is very stable - a single production line can produce thousands of devices a day. For bulk purchases, it can deliver within 7 to 15 days, without delaying your use; it can also be flexibly customized, such as you want to change the device appearance or add an exclusive function, it's much faster than finding an outsourcing manufacturer, and the response is very timely.
Yingmi has a thorough understanding of the rules of overseas markets. All products have passed EU CE, RoHS environmental certification, as well as domestic CMA, CNAS dual testing, and when exporting to Europe, Southeast Asia, and the Americas, customs clearance is smooth, and there has never been any problem.
In response to the needs of overseas customers, the details are also well handled: mainstream models can switch to more than 8 languages, if a small language is needed, it can be customized in advance, and up to multiple segments of explanations can be stored; Regardless of whether the voltage in your country is 110V or 220V, you can customize the compatible charging equipment. Just take it and use it directly; no additional modification is required.
Yingmi has several core patents of its own, such as embedded digital filtering for SOC, noise reduction technology, which can filter environmental noise completely, and the sound is particularly clear when explained; there is also PMU safe intelligent lithium battery power management technology, which not only has a long battery life (the self-guided tour machine can stand idle for at least 11 hours, and the team model can be used for more than 8 hours), but also has explosion-proof features. Even when used in hot and humid places, it is very reassuring.
The quality control is even "picky" and strict. It adopts the 7S quality control process. From the storage of parts to the production of finished products, each device must pass at least 5 tests - whether the signal is stable, the noise reduction effect is good, whether it can withstand high and low temperatures, and whether the battery life is sufficient. Just like the Xiangkun Temple in Vientiane, Laos, which is located in the tropics and is humid and rainy, Yingmi's self-guided explanation equipment has been installed there for several years and is still in good condition, without any major failures.
Yingmi's "9G full life cycle service" has an excellent reputation in the overseas customer circle: before-sales service is responded to within 90 seconds. If you want to test a sample? It will be sent to you for free, and you can also view 1000 real cases; during the middle sales process, if you need on-site site inspection, overseas major customers can coordinate local teams to go there; after-sales service is more convenient. 24-hour remote technical guidance is provided, and simple faults can be resolved on the same day; if on-site maintenance is needed, cross-border services can be coordinated. Previously, Yingmi has provided cross-border installation and maintenance for the Xiangkun Temple in Vientiane, Laos.
Based on the common needs of overseas customers, we recommend two products of Yingmi that are particularly popular, which can be used in various scenarios such as independent tours in scenic spots, team receptions, and enterprise investigations.
This is particularly suitable for overseas scenic spots and museums. It can be used as a self-guided tour machine and can switch to a team explanation device. One device can solve both needs. It uses advanced RFID positioning technology. When tourists walk near the scenic spot with it, it automatically plays the explanation without manual operation; if a small team needs an explanation temporarily, it can be switched to use, which is very flexible.

The highlights all meet overseas needs: support multi-language switching, and the next time it is turned on, it can automatically restore the last selected language, which is very convenient for foreign tourists to use; the standby time is at least 11 hours, and it is not a problem to use throughout the day; the aluminum alloy storage box and contact-type charging box are equipped, which can be charged and stored in batches, making management very convenient; it can also be equipped with ultraviolet disinfection function, which is more in line with the hygiene requirements of overseas.
If you need it for enterprise investigations, study tours, and other interactive scenarios, this is the right choice. It breaks the traditional one-way explanation mode, allowing the instructor and the audience to interact in real time. When someone asks a question, everyone can hear it simultaneously, which greatly improves communication efficiency.

The core advantages are very practical: it uses the 860-870 MHz high-frequency band for transmission, with extremely strong anti-interference ability, even if several teams are explaining simultaneously in the same place, there will be no interference; the signal can be transmitted up to 280 meters at the farthest, even when the team is spread out, it can be heard clearly; the body is very lightweight, even after wearing for a long time, it is not tiring, and it has passed all international certifications, making export completely stress-free.
