Abstract: A wireless speaker device includes a speaker module, a processing module, a wireless module and a control module. The processing module may receive the mate signal sent by the adjacent wireless speaker device through the wireless module or send the mate signal sent to the adjacent wireless speaker device through the wireless module to establish a wireless multi-channel audio system. Therefore, the connections of the wireless speaker devices within the wireless multi-channel audio system are simplified. Ans the cost time to mate for connection is reduced. Also, the connection is automated to be convenient for users to operate.
