The stability of its products has been tested in the long-term market, making it a reliable benchmark brand in the industry.   The stability of a wireless audio guide device mainly depends on four key dimensions:   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.   Dimension One: Signal Transmission Stability, Say Goodbye to Disconnection and Crosstalk   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.   Dimension Two: Battery Stability, Supporting Long-Term Use   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.   Dimension Three: Environmental Adaptability Stability, Dealing with Complex Usage Scenarios   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.   Dimension Four: Quality Control Stability, Reducing Long-Term Fault Rates   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.

There are many brands on the market, but Yingmi, which has been deeply engaged in the wireless tour guide field for 18 years, has become a hard brand for durability in the industry through solid R&D accumulation and strict quality control. Its classic model, the E8 wireless tour guide, has embedded "durability" into every design, catering to various usage scenarios of customers. It has been verified by thousands of projects worldwide and truly carries the banner of "long-term usability".   When choosing a durable wireless tour guide, these four core dimensions must be closely watched   Many customers think that "durability" means being able to withstand drops, but this is not the case. The durability of a wireless tour guide is a comprehensive matter. It depends on the material wear and tear over the long term, the stability of performance, the ability to adapt to different environments, and whether the battery life is sufficient. These four dimensions directly determine how long the device can be used and whether it will cause trouble. They are also the key points I repeatedly emphasize when helping customers select models.   Material and Craftsmanship: The Foundation for Withstanding Daily Wear and Tear   Wireless tour guides are frequently handled and moved around. During the process of tourists picking them up and putting them away, bumps and scratches are common. If the material and craftsmanship are not up to par, problems such as cracked shells, unresponsive buttons, and loose interfaces will occur within a few months, which is even more costly. Especially in places with high foot traffic and high reuse rates like museums and scenic spots, the equipment must be made of anti-drop and anti-wear materials and be assembled with precision to withstand daily wear and tear.   Stable Battery Life: The Key to All-Day Operation without Interruption   Most customers operate their devices throughout the day. If the device runs out of power in the middle of the day or charges inconsistently or incompletely, it will directly disrupt the service. A durable wireless tour guide not only needs to be equipped with a good battery but also have reliable intelligent power management technology. This ensures it can last the entire day and avoid overcharging, which can damage the battery. This way, the battery lasts longer and there is no need to frequently replace the device.   Interference Resistance: The Confidence to Perform in Complex Environments   Large exhibitions, museums, and factory areas have very complex signals. Mobile phone signals and radio frequencies can easily interfere with tour guides. Devices with poor interference resistance may experience cross-talk or disconnections, making it difficult for tourists to hear clearly and directly affecting the reputation. Therefore, durable devices must have mature interference resistance technology to ensure stable signals even when multiple teams are using them simultaneously, without causing any disruptions.   Environmental Adaptability: Adapting to Global Climates is Essential   Customers operate their businesses in various locations, some with high temperatures and intense sunlight, and others with high humidity and frequent rain. If the equipment cannot withstand these climates, it is prone to malfunctions. In addition, the protection during batch charging and storage should not be ignored. Only by paying attention to these details can the overall durability of the equipment be truly enhanced and unnecessary damage be avoided. Durability is not just a slogan; it is a comprehensive quality control process   Many brands in the industry only focus on short-term planning, making a quick profit and then leaving. They do not attach importance to R&D for durability. However, Yingmi is different. Since its establishment in 2007, it has been dedicated to the wireless tour guide field for 18 years, treating "durability" as its core. From R&D to production, every step is closely monitored to truly lay a solid foundation for durability.

However, human explanations are limited by the pace, the number of people, and the language, and inevitably some details may be missed; traditional self-service audio guide devices often have problems with inaccurate positioning, noisy sound quality, and insufficient battery life, causing visitors to miss crucial information. Yingmi, which has been deeply involved in the audio guide industry for 18 years, has already understood this problem and launched the i7 ear-mounted fully automatic sensor guided tour machine. With its lightweight design, precise positioning, and high-definition sound quality, it captures every detail of the guided tour throughout the process, making it the preferred choice for customers to build an efficient guided tour system.   i7 Self-Service Audio Guide: Accurately capture details, say goodbye to visit regrets   The functions of i7 Self-Service Audio Guide in terms of positioning, sound quality, and language adaptation all incorporate the idea of "not missing details". It can be adapted to various visiting scenarios.   RFID precise positioning, no matter which guided tour point, it is not absent   When visitors miss some details, it is mostly because the equipment's sensing is inaccurate - either triggering prematurely and missing the previous content; or responding slowly and missing the current exhibit's explanation. i7 is equipped with the RFID-2.4G interference-free star distribution system, optimizing the sensitivity and anti-interference ability. It can precisely switch signals within a range of about 1 meter, especially suitable for scenarios with dense guided tour points such as museums and precision product exhibition halls. Just place the signal trigger at each guided tour point, and when visitors wear i7 and approach, the corresponding explanation content will automatically play. After leaving, it will automatically stop. There is no need for manual operation, completely avoiding missed or incorrect listening. The trigger uses long-life, low-power high-quality chips, does not require wired power supply, and a single battery can last for three years. Even in outdoor scenic spots or large exhibition halls, it can operate stably and ensure that every detail of the explanation can be accurately delivered to the visitors' ears.   High-definition noise reduction quality, clear and distinguishable details description   If the details cannot be delivered clearly, sound quality is the key - whether it is the description of the exhibit's craftsmanship, the detailed explanation of the historical background, or the interpretation of product technical parameters, even a little noise may cause visitors to miss the key information. i7 is equipped with Yingmi's core SOC embedded integrated digital noise reduction technology, which can effectively filter the noise from the crowd and equipment interference. Combined with AI lossless original sound processing, the explanation sound quality is clear and transparent, and every detail description can be clearly heard.   In addition, i7 supports various audio formats such as MP3 and can store a large amount of explanations. It can accurately reproduce the tone and detailed description of the audio guide, making visitors feel like they are listening to a dedicated explanation. Even in large exhibition halls or crowded scenic spots, visitors can immerse themselves in listening to every wonderful moment without missing key information due to sound quality issues.   Multi-language flexible adaptation, no language barrier for detail transmission   In visiting scenarios, multi-language adaptation is the key to transmitting details - if visitors from different countries do not understand the explanation, no matter how rich the details are, they will be useless. i7 precisely meets this demand, with a standard of 8 languages. If foreign customers have needs, it can expand to more minor languages to cover most countries and regions in the world, completely breaking language barriers.   The device can flexibly switch languages and has language switching alert sounds. Visitors can choose the language they are familiar with themselves. What's more, it can remember the last selected language and does not need to reset when starting up next time, avoiding missing details due to inconvenient operation. Whether it is international museum exhibitions, multinational enterprise exhibition halls, or global scenic spots reception, i7 can enable every visitor to accurately capture details and have a complete visiting experience. Lightweight power supply, continuous protection of details without interruption   During a long visit, the portability and power endurance of the equipment directly affect whether one can consistently capture details - if the equipment is too heavy, it will distract you, and if the power endurance is insufficient, the subsequent detailed explanations will be missed. The i7 is a compact ear-mounted all-in-one device, weighing only 18 grams. It is very lightweight among similar products in China. It is comfortable to wear and even after wearing it for a whole day, there is no feeling of weight. It enables visitors to concentrate on listening to the explanations and not miss any details.   The power endurance is also reliable. The i7 can work continuously for more than 7 hours, and the standby time is not less than 11 hours. It is completely fine to last through a whole day of visiting. It also has a low power alert function, which reminds you to charge in advance to avoid interruption during the journey. It is paired with an exclusive contact charging box that can charge 36 devices at a time. There is also intelligent charging management, which can ensure charging speed, protect battery life, and can be equipped with an ultraviolet disinfection function, which is particularly in line with customers' high requirements for hygiene. The dedicated storage box has an all-aluminum outer frame, with silicone grooves and sponge inside. It is convenient for long-distance transportation or daily storage and is suitable for the needs of exhibition and off-site transfer in scenic spots. 18 years of industry accumulation, solid foundation for detail transmission   The i7 can precisely capture every detail of the visit.
