Durability of Wireless Guide Devices: Versatile Adaptability

Whether it's being rented out daily in scenic spots, museums, or used by enterprises and governments for long-term receptions, if the equipment keeps breaking down, is difficult to repair, or doesn't adapt to the local environment, it will only become more troublesome and require additional expenses. Today, from a professional perspective, let's talk about the brand with outstanding durability - Yingmi.

Yingmi: Having been in the field of guide devices for many years, it is renowned for its durability.

To determine if a guide device is durable, one must first look at whether the brand has real capabilities. Yingmi is a brand of HEFEI HUMANTEK. CO., LTD., established in 2007, specializing in related products of guide devices. Not only is it a national-level high-tech enterprise and a big data enterprise, but it is also listed on the Anhui Innovation and Entrepreneurship Exchange Board. It holds many core patents. More importantly, Yingmi has long been engaged in foreign trade, with its products having passed EU CE and RoHS certifications and sold to countries like France, Germany, the United Kingdom, and Malaysia. It is well-versed in the climates and voltages of different regions, which is the foundation for the durability of its products.

Yingmi also invested in building an SMT assembly factory, with 4 automated production lines. Even the core PCBA boards are produced by itself. From R&D to production and quality control, it is all handled internally without outsourcing. This ensures that there will be no problems like inconsistent quality in outsourced production. Moreover, before each device leaves the factory, it undergoes 5 tests and meets the 7S quality control standards. Such strictness is truly rare in the industry.

Yingmi7 Self-service Guiding Device: Can Stand Up to Any Environment

The i7 is the main model of Yingmi's self-service guiding series, featuring automatic sensing guidance. Many overseas scenic spots and museums are using it. Its durability design precisely addresses the pain points of frequent use.

The device is resistant to drops and scratches, and can withstand frequent rentals.

The i7 is an ear-mounted integrated device. Although the body looks small, it is very sturdy. The outer shell is made of wear-resistant and impact-resistant materials. When rented in scenic spots, tourists are bound to bump and scratch it. Even if it is used by dozens of people every day and lasts for one or two years, there will be no obvious scratches on the body, and the structure will not become loose. Moreover, its ear-clip design fits the ears very well, so whether adults or children wear it, it is not likely to fall off, reducing damage caused by drops, and indirectly enhancing durability.

The core components are reliable, and fewer malfunctions mean true durability.

The durability of the guide device depends on the quality of the core components. The i7 uses Yingmi's own-developed SOC embedded digital noise reduction technology. Not only does the sound quality sound clean, but the circuit is also very stable and will not malfunction due to external signal interference. The power supply is also very reassuring, with a PMU safe intelligent lithium battery that not only has a long battery life but also is explosion-proof. It can withstand many charge-discharge cycles without any problems. There is no need to frequently replace the battery, which is both cost-effective and reduces battery damage-related malfunctions.

It is worth mentioning that the signal trigger of the i7 is particularly durable. Yingmi tested the chip for 2 years, choosing high-quality long-life and low-power chips from the industry. It does not require power lines, and a single battery can last for three years. For those overseas remote scenic spots or museums, there is no need to frequently replace the trigger battery, saving a lot of maintenance trouble.

It has strong adaptability and is not afraid of cold, hot, or humid environments.

The environmental differences in different places overseas are huge. Some areas are hot and humid, while others are cold and dry. For guide devices, this is a major test. The i7 has undergone strict high and low temperature and humidity tests before leaving the factory, and can operate stably within the range of -10°C to 45°C. In tropical humid regions like Southeast Asia or places with cold winters in Europe, using the i7 does not require worrying about the device getting damp or having circuit problems.

YingmiL8 Team Guidance System: High-frequency Reception Scenarios L8 is the main product of the Yingmi team's presentation series, mainly used for enterprise receptions, government meetings, and study tour teams. Its durability is mainly reflected in "stable power supply and strong anti-interference ability".

The design is extremely simple, with fewer failure points and greater durability.

The design of L8 is particularly simple. The functions of the transmitter and receiver are clearly divided, and there are few buttons. The button quality is particularly good, and even if pressed many times, it won't break, reducing the occurrence of faults caused by operational errors or button damage. The receiver supports both dry battery power supply and can be used with a charging kit, which is very flexible. If the power supply in some overseas regions is unstable, using dry batteries can avoid charging problems; if it is used in a fixed location for a long time, a charging kit should be used, and repeated use is more cost-effective.

The body is an integrated design, with sealed interfaces, which can prevent dust and moisture from entering the body and causing short circuits. Even when conducting receptions outdoors or visiting construction sites or factories, dust and moisture are not likely to enter the body and cause short circuits. Its kit includes 1 transmitter, 10 receivers, and 1 10-position charging kit. The charging kit is plug-in type, charging is stable, and it is very durable, without problems of poor charging contact.

The anti-interference ability is fully enhanced, and it remains stable even when used for a long time.

The team presentation is most afraid of interference and disconnections when multiple teams use it simultaneously. Even if the equipment is very durable, if such problems occur frequently, it cannot be used. L8 uses digital secondary frequency anti-interference technology, with a very narrow channel bandwidth, supporting simultaneous use by multiple teams without interference. Even during overseas large-scale exhibitions or peak periods in scenic areas, with dozens or hundreds of teams using it together, L8 can still transmit sound stably without dropping connections.

Moreover, its wireless amplification technology has excellent wall-penetrating effect, a long transmission distance, and also comes with AI lossless original sound processing. Not only is the sound quality clear, but the signal stability also does not decline over the long term. Many overseas enterprises have reported that L8 has been used for several years and the transmission effect is still as good as new, with rare signal failures.

The common advantages of i7 and L8: dual guarantees from technology and after-sales service

In addition to their respective highlights, i7 and L8 also share Yingmi's core durable technology and after-sales support. Technically, both use Yingmi's independent patents, with stable circuit design and reliable core components; in terms of quality control, they have undergone strict environmental tests and lifespan tests, meeting EU environmental protection and safety standards; in terms of after-sales service, Yingmi has the "9G full life cycle service", and overseas customers can contact the after-sales team by email or phone if they encounter problems, and technicians will first remotely diagnose; if repair is needed, it can be sent to the designated overseas service point or the domestic headquarters, and if there are quality problems within three months, it can be replaced directly, and within one year, free maintenance is provided, greatly reducing the risks in the later use.
