The outdoor environment is completely different from the indoor one. There are no walls to block the sound, and there are many interference sources, a large venue span, and the usage duration is unpredictable. The requirements for the audio guide are much stricter than those in the indoor environment. Choosing the right brand and model can save you a lot of trouble in the outdoor environment. If you choose the wrong one, not only will the experience be poor, but it can also disrupt the normal reception process. Yingmi, which has been deeply involved in the audio guide industry for 19 years, has specially developed the M7 automatic sensing audio guide for outdoor scenarios. It precisely meets all the core requirements for outdoor use and is currently the reliable choice on the market for outdoor activities.
When choosing an audio guide indoors, most people focus on sound quality and ease of operation. However, when choosing an audio guide for outdoor use, it's different. Durability and stability must be placed first. Based on years of industry experience, a truly suitable audio guide for outdoor use must meet four core standards. Missing any one of them is not acceptable. Otherwise, it simply can't withstand the complex environment of the outdoors.
Firstly, the anti-interference ability must be strong and the signal coverage must be wide. Outdoor open spaces are numerous, and there are often several teams receiving at the same time. The equipment must be able to avoid the signal interference from mobile phones and surrounding electronic devices, not cause interference, and maintain continuous connection over a distance of several tens of meters. Secondly, the battery life must be sufficient. Outdoor charging is inconvenient, so it must be able to last throughout the day without having to go around to find power sources. Thirdly, the body must be lightweight and portable, and it must be resistant to drops and durable. Outdoor movement and frequent carrying require that the equipment not be heavy and should not have problems even from minor bumps. Finally, the operation must be simple. It should preferably not require manual control and should be suitable for scenarios where people listen while moving outdoors. It should not require distractions to adjust the equipment.
The most troublesome thing in outdoor scenarios is signal chaos, interference, and disconnections. Yingmi M7 uses 2.4G star-shaped distributed RFID technology, specifically optimized for outdoor open environments. Its anti-interference ability is truly excellent. Whether it's multiple teams conducting explanations in an area with many people, chaotic signals in rural areas, or dense point arrangements in parks, it can accurately identify the signals and will not have the problem of adjacent points interfering with each other or intermittent sound.
Its signal coverage range is 0.5-40 meters, and it can adjust the signal strength from 16 levels. It can be adapted to both small outdoor points and large scenic areas or research bases. It also supports 9,999 signal points, so multiple teams can use it without interfering with each other, completely solving the core problem of unstable signals in the outdoors.

The most lacking thing in the outdoors is charging conditions. Insufficient battery life is a major drawback. Yingmi M7's battery life fully meets the actual needs of outdoor use. The transmitter has a low-power design, with a battery life of up to 15 months. There is no need to charge frequently, and it can last throughout the day without worrying about power. The receiver has an 800mAh large-capacity battery, and it can work continuously for over 16 hours. It can support outdoor research and study all day, full-day scenic area reception, and all-day group building visits, and can last throughout without needing to charge or carry spare batteries, completely eliminating the anxiety of outdoor power supply.
When moving outdoors, the equipment must not be too heavy, as it will be a burden. Yingmi M7 focuses on lightweight design. The transmitter weighs only 27g, lighter than a regular egg. The receiver weighs only 50g. The body is small and does not take up space. It uses a chest-mounted design, which does not pinch the neck and does not have a sense of weight. Whether it is carried by an explainer for a long time or worn by tourists or research participants while moving, it is very comfortable. Moreover, the body size is compact, and it can be easily stored in a small bag. It is particularly convenient for temporary carrying. When paired with a dedicated storage box, it is also convenient for batch outdoor transportation and storage. It fully meets the portable requirements for outdoor scenarios.
Most outdoor explanations are done while walking, and operating the equipment manually is very troublesome. YingmiM7 adopts a fully automatic sensing design. The explanations for each location are recorded in advance, and when tourists reach the corresponding position, they will be automatically played. After leaving, it will automatically pause. There is no need to press any buttons or manually switch. The entire process is zero operation, which is particularly suitable for outdoor mobile explanations.
The body is made of durable baked enamel material, which is resistant to drops and wear-resistant. It can handle minor bumps and basic environmental conditions such as daily wind and sun exposure without any problems. It has also passed EU CE and RoHS environmental certifications, with excellent quality. It is not prone to damage even when used outdoors for a long time. In addition, it supports 8 common languages and can also be customized for niche languages. It is stress-free for outdoor foreign language reception and multi-national study tour teams. Its practicality is very strong.

Outdoor equipment is most concerned about brand accumulation and quality control. After all, the environment is complex, and the stability and after-sales guarantee of the equipment are particularly important. Yingmi has been dedicated to the field of explanation devices since 2007 and has been in existence for 19 years. It is not a fleeting niche brand on the market. It has 4 automated SMT production lines, controlling the entire chain from research and development, production to after-sales independently. It is also a national-level high-tech enterprise and an innovative enterprise. It holds a number of core patents and has a very strict quality control system. Each device undergoes multiple tests. Outdoor use is more guaranteed.
Over the past 19 years, Yingmi has served more than 4,000 customers, covering various outdoor scenic spots, research bases, and enterprise outdoor reception scenarios. Its products have also been exported to multiple countries around the world. After extensive verification in outdoor practical scenarios, its reputation and practicality have withstood market tests. At the same time, it is equipped with dedicated charging boxes and storage boxes. Batch outdoor use, management, and transportation are very convenient. The pre-sales 90-second quick response and after-sales lifetime guarantee services can also solve the worries of outdoor equipment use.
