Many-to-Many Two-Way Communication Solution
The 2.4G wireless tour guide system consists of an unlimited number of guide units and an unlimited number of visitor units. Once paired with the guide units, the visitor units can hear the voices of multiple guides upon startup. The guide units also have a listening function, with a normal range of up to 100 meters. If the distance exceeds the reception range, the visitor units will receive a sound prompt. A fully charged visitor unit can be used continuously for one week, meeting the needs of a typical travel journey. In addition to speech, the guide units can also play music or provide site introductions through audio interfaces.

Tour guide systems are divided into master and slave units, both capable of two-way communication. During group tours, there is only one tour guide master unit, while the tour guide slave units and user units have unlimited quantities.
The tour guide master unit can release the binding between user units and tour guide slave units, enabling the function for individual/group dispersal.
The tour guide device can remotely shut down all tourist devices
In the event of wireless interference, the tour guide's host device will switch channels, and the tourist devices and guide's sub-devices will automatically follow suit
Simultaneous Input of External Audio and Microphone Signals OR Select Input of External Audio and Microphone Signals
The tour guide's host device can only have real-time intercom with one tour guide sub-device at a time, but other tour guide sub-devices and tourist devices can all hear the intercom content. To engage in intercom, tour guide sub-devices only need to grab the microphone, while tourist devices have only listening functionality.
