Many emerging brands rush to launch new products to seize the market, often neglecting the core aspect of stability. However, Yingmi has been focusing on the field of voice explanation and display since its establishment in 2007. Over the past 18 years, it has formed a complete chain of services from research and development, production, sales, installation, and after-sales. It has served thousands of customers, covering various fields such as scenic spots, museums, government units, and large enterprises. It has also obtained multiple international certifications such as EU CE and RoHS. Its products are exported to multiple countries and regions around the world. The stability of its products has been tested in the long-term market, making it a reliable benchmark brand in the industry.
When many customers are selecting, they often fall into the misconception that "the higher the parameters, the better". In fact, the stability of a wireless audio guide device mainly depends on these four key dimensions. Missing any one of them is not acceptable. These four dimensions directly determine the performance of the device in actual use and are the key to distinguishing between high-quality products and ordinary ones. This is also the core reason why Yingmi M7 can stand out.
Signal transmission is the foundation of a wireless audio guide device. How stable the signal is can be seen at a glance. In indoor exhibition halls with many walls and complex obstructions, and outdoor scenic spots with open areas and multiple teams operating simultaneously, if the signal is unstable, problems such as disconnection, crosstalk, and delay will come knocking. The experience of explanation will be instantly compromised. Common industry pain points include that some low-priced products use simple wireless technology, with short transmission distances and weak anti-interference capabilities. When multiple teams use it, crosstalk is severe, and frequent disconnections occur in areas with many walls, seriously affecting usage.
To determine whether the signal transmission is stable, three key points need to be considered: transmission technology, channel bandwidth, and anti-interference design. High-quality wireless audio guide devices will adopt advanced modulation technologies and reasonable channel planning, which can avoid external signal interference from mobile phones, radios, etc., and achieve stable transmission over long distances, adapting to different scenarios' needs.
Battery capacity directly determines the scenarios where a wireless audio guide device can be used. Scenic spots and museums receive a large number of visitors every day, so the equipment needs to operate continuously from morning to night; enterprises' receptions and large exhibitions may have continuous explanations lasting for several hours or even several days. If the battery capacity is insufficient, frequent charging will not only delay efficiency but also cause interruptions in the explanation, causing trouble for both customers and organizers.
Battery stability is not only about battery capacity, but also about power management technology. High-quality products will adopt efficient power management solutions, which can ensure battery duration and reduce power consumption, avoiding "phantom power" issues. At the same time, they will be equipped with convenient charging devices that support simultaneous charging of multiple devices, making it more convenient to use.
The usage scenarios of wireless audio guide devices are particularly diverse. There are indoor exhibition halls with constant temperature and humidity, as well as outdoor scenic spots with high temperatures, rain, and dust; there are indoor exhibition halls with narrow spaces and dense exhibits, and outdoor squares with open areas. Poor environmental adaptability of the product is prone to failure in extreme temperatures, humidity, and dusty environments, which not only affects the service life but also lowers the usage experience.
Whether the environmental adaptability is stable mainly depends on the device's material, sealing design, and hardware protection capabilities. High-quality products will use durable materials, combine good sealing design, have certain waterproof, dustproof, and shockproof capabilities, and be able to adapt to different temperature ranges. No matter what complex scenarios, they can operate stably.
Wireless audio guide devices are mostly high-frequency-used devices, especially in scenic spots and museums, where they are used by a large number of tourists every day, and wear and tear are rapid. Products with poor quality control are prone to problems such as earphone malfunction, button failure, and reduced sound quality over time. Not only do they require higher maintenance costs, but they also affect normal usage.
The stability of quality control depends on a brand's production strength, quality control system, and testing standards. Brands with their own production capabilities and a well-established quality control system will strictly test each device from component selection to final production, controlling quality at multiple stages to ensure long-term stability and reduce failure rates.
As a core product of Yingmi, the M7 wireless guide device leverages the brand's 18-year technical accumulation and quality control advantages. It performs well in four core stability dimensions. It also has advantages such as easy operation and support for multiple languages, and is suitable for various scenarios such as scenic spots, museums, enterprise receptions, and exhibitions. It has become the preferred choice for many customers.
M7 adopts an RFID-2.4G star distribution system design, equipped with advanced digital encoding area positioning identification technology and spread spectrum communication technology. It successfully solves industry pain points such as interference between adjacent guidance points and difficult position encoding recognition, achieving precise, clear, and low-noise audio transmission. The device supports 9999 signal numbers, with signal strength adjustable in 16 levels, covering a range of 0.5-40 meters. Whether in indoor exhibition halls with complex wall obstructions or outdoor scenic spots with open areas, it can achieve stable transmission without disconnection or crosstalk.
In addition, M7 adopts digital secondary frequency anti-interference technology, which can effectively avoid external signal interference from mobile phones, radios, etc. When multiple teams use it simultaneously, they can also independently explain and not interfere with each other. It is particularly suitable for multi-team parallel explanations in museums, exhibitions, etc. Visitors can enter the guidance area with the device, without any operation, and when they approach the guidance point, they will automatically sense and play the corresponding audio, which is both convenient and ensures stable guidance experience.
M7 adopts a large-capacity battery design. The receiver is equipped with an 800mAh battery, and can continuously work for more than 16 hours. The battery life of the transmitter is even up to 15 months, fully meeting the needs of all-day use in scenic spots and museums, without frequent charging. The device uses PMU safe intelligent lithium battery power management technology, which is particularly energy-efficient, effectively reducing power consumption and avoiding "phantom power", and supports 5V Mini USB charging. It can be charged simultaneously for 36 or 48 devices with an exclusive charging box, and can also be equipped with an ultraviolet disinfection function, which is convenient and hygienic.
Moreover, the transmitter of M7 does not require power supply through wires. One battery can last for three years, significantly reducing maintenance costs in scenic spots and museums, and avoiding the impact of line failures on equipment stability.
The shell of M7 is made of pure white lacquer process, with durable material and good sealing design. It has certain waterproof and dustproof capabilities and can adapt to different environments. The device has undergone strict environmental tests and can operate stably within the temperature range of -10°C to 45°C. Whether in hot and humid outdoor scenic spots or humid and rainy environments, it can be used normally without easily breaking down.
At the same time, M7 adopts a chest-hanging design, with the receiver weighing only 50g, which is lightweight and comfortable to wear, suitable for long-term use, especially suitable for tourists in scenic spots and exhibition visitors. The shell has undergone wear-resistant and anti-drop treatment, and can still operate stably after long-term high-frequency use, with a very low failure rate.
