Abstract
A wireless speaker system is provided. The system includes at least one main light emitting diode (LED) lighting device including a wireless fidelity (Wi-Fi) radio frequency module and a wireless audio module. The system also includes at least one auxiliary LED lighting device including the wireless audio module. Further, the system includes a smart terminal. The main LED lighting device is wirelessly connected to the smart terminal through the built-in Wi-Fi radio frequency module. The smart terminal sends an audio signal to the main LED lighting device, and then the wireless audio module in the main LED lighting device transmits the audio signal to the auxiliary LED lighting device. The auxiliary LED lighting device sends feedback information to the smart terminal through the main LED lighting device.
