When many customers purchase automatic induction lecturers, they tend to focus on the lightness of the appearance, the number of languages supported, but they often overlook the most crucial signal indicators. After purchasing, they frequently encounter problems.
Point sensing must be precise, without interfering with points or triggering mistakenly.
This is the core signal requirement of automatic induction lecturers. In scenic spots and museums, the point locations are usually close to each other. Ordinary equipment is prone to problems: before reaching the point, the explanation starts; after passing the point, there is no response; or the signals of adjacent points directly interfere with each other, playing incorrect explanations. A qualified device must be able to accurately identify point signals, triggering the explanation only when reaching the corresponding area, and automatically stopping when out of the coverage range. The entire process must not be chaotic or misjudged.
The anti-interference ability must be strong, without interference in dense scenarios.
There are many electronic devices in venues and the signal environment is chaotic. In addition, multiple devices are used simultaneously, which easily leads to signal interference. Reliable automatic induction lecturers must use dedicated anti-interference frequency bands and independent signal encoding. It can block external noise such as mobile phones and public broadcasts, and also avoid interference between multiple devices, ensuring that each device can stably receive the corresponding point signals.
The signal coverage can be adjusted to adapt to different scenarios.
The spacing between point locations varies greatly in different scenarios. Small exhibition halls have dense point locations, requiring precise coverage in a small area to prevent accidental triggering; large scenic areas have scattered point locations, so an appropriate coverage range is needed to avoid no signal in long distances. High-quality equipment must support adjustable signal strength, which can not only meet the precise sensing in small spaces but also adapt to stable reception in large scenarios, without the awkward situation of chaotic signals near the distance and no signals at a long distance.
Yingmii7: Real and reliable signal, stable in all scenarios
As a professional ear-mounted automatic induction lecturer, Yingmii7 has been optimized throughout the process from signal module development to frequency band selection, focusing on "stable, precise, and anti-interference". It fully meets the three standards we just mentioned and has made special upgrades to address the signal pain points of self-guided tours. In practice, its performance is much better than that of ordinary non-brand products on the market.
RFID precise modulation, point sensing without errors
Yingmi i7 uses mature RFID modulation technology and an exclusive non-interference star-shaped distribution system to achieve precise signal switching within a 1-meter range, completely solving the old problems of traditional induction devices triggering mistakenly and interfering with points. When a visitor wears the i7 receiver and walks to the designated explanation point, the device can quickly sense the signal emitted by the point transmitter and immediately play the corresponding explanation content; before sensing the next point, it will complete the current content completely, and automatically pause when leaving the signal coverage area. The entire process does not require manual operation, and the sensing is extremely precise, never playing the wrong content or starting prematurely.
This device's signal transmitter supports 9999 independent signal encodings. Even if the exhibits in the exhibition hall are closely packed or the adjacent points in the scenic area are close, it can distinguish different points through independent encoding, fundamentally eliminating the problem of signal confusion and interference between adjacent points, truly achieving sound when people arrive and sound ceases when people leave. It is very convenient to use.
Exclusive communication frequency band, anti-interference without noise The Yingmii7 receiver operates on the exclusive 860MHz-870MHz communication frequency band, deliberately avoiding the commonly used signal frequency bands such as those of mobile phones, Bluetooth, and public broadcasting. At the frequency level, it completely isolates external interference. Additionally, with 9999 adjustable channels, multiple devices can be used simultaneously in one venue and each device can independently receive signals without interfering with each other.
For situations where there are walls and display cases blocking in the venue, the signal module of i7 has also been optimized for penetration. Even with slight obstruction, there will be no signal disconnection or deviation. Coupled with stable wireless communication power control technology, it completely solves the problem of difficult signal identification and mutual interference in adjacent points. Tourists can hear clear and clean explanations without any noise or crosstalk, providing an excellent experience. The signal can be adjusted, and it is suitable for various scenarios.
The signal can be adjusted, and it is compatible with different scenarios
The signal transmitter of Yingmii7 supports 16 levels of signal strength adjustment, and the coverage range can be freely controlled within 0.5-40 meters. It can perfectly adapt to the needs of different scenarios. For densely located points such as small exhibition halls and cultural relic display halls, the signal strength can be lowered to achieve precise sensing in a small area and avoid touching adjacent points by mistake; for scattered points such as large scenic areas, enterprise parks, and outdoor exhibition halls, the signal can be raised to ensure an appropriate coverage range. Tourists can receive the signal steadily within the point range and will not encounter the problem of no response at a long distance.
This adjustable signal design makes i7 not picky about scenarios. Whether it is a densely located small exhibition hall indoors or an open large scenic area outdoors, it can find the most suitable receiving effect by adjusting the signal strength. Its versatility is particularly strong, and there is no need to replace the equipment separately for different scenarios.
Low power consumption and stable connection, no signal attenuation for a long time
Many automatic sensing audio guide devices have a common problem. Besides short battery life, when the battery is low in the middle of use, the signal will also weaken. The sensing becomes particularly sluggish. Yingmii7 uses a low-power signal module and PMU intelligent power management technology. The receiver can work continuously for 7 hours when fully charged and has an idle duration of over 11 hours. The signal strength remains stable throughout the process, and there will be no problem of signal weakening or sluggish sensing due to power consumption. It can be used all day long, and the signal performance remains consistent throughout the day, completely eliminating the worry of signal drop-off.
19 years of industry expertise, signal strength guaranteed
The outstanding signal performance of Yingmii7 is inseparable from the brand's 19 years of industry accumulation. Yingmi was established in 2007 and has been dedicated to the field of audio guide devices for 19 years. It did not blindly expand product categories but remained rooted in the research and development of core technologies such as wireless signal transmission and automatic sensing positioning. It has its own 4 automated SMT production lines and a complete product quality control system. Every i7 is tested for multiple signals before leaving the factory to ensure that the signal stability and sensing accuracy meet the standards.
