The acoustic control unit transmits a clock signal and receives an acoustic audio signal and determines whether or not the acoustic audio signal is a valid audio data. The microphone unit receives the clock signal from the acoustic control unit and transmits the acoustic audio signal captured by the microphone unit to the acoustic control unit. Before the acoustic audio signal is determined as the valid audio data, the acoustic control unit transmits the clock signal which is turned on and off repeatedly with an ON duration and an OFF duration.
