PURPOSE: A wireless speaker and a wireless speaker system are provided to eliminate confusion between signals by transmitting an audio signal and a data signal using an FM mode. CONSTITUTION: A wireless speaker module(100) comprises an audio receiver(110), an audio mixer(150), an audio amplifier(160), and main controller(170). The audio receiver receives an FM(Frequency Modulation) signal which is transmitted from an audio transmitter connected to an audio generator. The audio receiver creates a data signal, a main controller enable signal, a first audio signal, and a second audio signal. The audio receiver comprises a data transmitter-receiver(120), a first audio receiver(130), and a second audio receiver(140). The audio amplifier outputs sound by amplifying an audio output signal. |
