In some lively tourist attractions, we often encounter such a scene, the tour guide wears a wireless audio guide to introduce the story about the scenic spot, followed by a group of tourists wearing similar headphones, sometimes laughing, sometimes surprised, and sometimes confused. In some government and enterprise units, we occasionally encounter such a scene, a person wearing a wireless audio guide leads a large group of people wearing similar headphones, telling the development history of the unit. The wireless audio guide device they use solves a big practical problem in the rapid progress of wireless network. It lets us say goodbye to the era of communication relying on roar, and the sound can be passed into other people's ears silently. But how does such a convenient wireless audio guide work?

The wireless audio guide collects audio data through a microphone, then converts the audio into a digital signal through the encoding module, and then transmits it to the receiver through the wireless chip, and the receiver decodes and plays the audio. In addition, the receiver of the wireless audio guide adopts a one-piece wearing design, which solves the trouble of wearing. The receiver also has a volume adjustment button, and users can choose according to their personal habits. The wireless audio guide adopts the 2.4G international common frequency band, and each device has an independent ID, which ensures the stability and confidentiality of signal transmission, and can resist electromagnetic interference in various occasions, so it is very suitable for use in government and enterprise units. The emergence of the wireless audio guide solves the communication problem in specific scenarios, with the innovation of technology, its function is also further improved.
