When the one-to-many audio tour guide has not yet appeared, when many people visit the reception, it is usually troublesome to explain the equipment, but since the one-to-many audio tour guide appears in the public's field of vision, the team reception is no longer troublesome. The one-to-many audio tour guide can allow one person to speak and many people to listen. It has a transmitter and a receiver to explain and listen. The speaker can use the transmitter to speak, and the audience can also wear the receiver to listen. The one-to-many audio tour guide even if many people use it at the same time, there will be no problem of signal interference. The use of a one-to-many audio tour guide to explain the tour guide can not only protect his throat from the damage caused by long-term loud speech, but also there will be no noise.
Because the one-to-many audio tour guide uses a dedicated transmission channel, it can transmit the content of the explanation to the receivers worn by the audience through the audio transmission channel, rather than amplifying the sound by amplifying the sound like the little bee let all listeners hear. In addition, the one-to-many audio tour guide has multiple frequency bands, which can realize the function of simultaneous interpretation. The interpreter can use one frequency band with the speaker to speak and listen, and then the interpreter can communicate with the need for translation through another frequency band. Therefore, in addition to being used in scenic spots, the one-to-many audio tour guide can be used in large-scale international conferences, corporate receptions, factory visits, education and training, because it can not only transmit audio content confidentially, but also shield surrounding signals interference.
