However, a large number of tour guides will put a lot of pressure on management, so an electronic device is needed that can replace manual tour guides to the greatest extent. In the traditional way of explaining, tour guides explain through traditional loudspeakers, and the sound quality of the explanation is not clear. The work pressure of tour guides is high, but the existing multi-channel wireless broadcasting partition explanation system can only conduct audio broadcasting explanations in order, and cannot enable tourists to listen to what they want, without the integrity and continuity of audio explanations
