How has the improvement of living standards changed us? The current economic progress and development has also brought about great changes to our schedule and life. In the past, travel before just think about it, now travel is say go to go. In the past, the tour guides were shouting and leading the group with a loudspeaker, but now they use a device called a audio tour guide to lead the group. This audio tour guide has appeared in the public's field of vision in recent years. Its function is to replace the original loudspeaker, because the loudspeaker makes a lot of noise when explaining, the purpose is to be heard by all tourists by broadcasting the sound. But even so, because of the sound transmission method of the amplification equipment, it is always inaudible when it is far away, and the sound is too loud when it is too close.

The sound transmission method of the audio tour guide is very different from this kind of amplifying equipment. It has its own special explanation channel and transmits the audio content through digital encryption technology, which can not only transmit the sound clearly, but also transmit the audio content, it's guaranteed that the content will not be disturbed. Tourists can adjust the volume by themselves when using the audio tour guide to listen, and choose the appropriate volume to listen to the content according to their own habits. Now, in addition to being used when audio tour guide lead a group to visit, audio tour guide can be used in museums and exhibition halls. The audio tour guide can be used one-to-many, and the teams will not interfere with each other, and can effectively isolate the surrounding signal interference.
