Abstract:
[Problem] To provide a technology whereby power consumption can be reduced by reducing wasteful output of audio signals. [Solution] By comparison of an output volume level Vout of an output audio signal from a wireless speaker  1  with an input volume level Vin of an input audio signal to an audio controller  2,  a volume level ratio Vin/Vout between the signals is monitored (S 111 ). Moreover, when the volume level ratio Vin/Vout has dropped by a predetermined amount or more within a predetermined time period (S 113,  S 120 ), a listener carrying the audio controller  2  is determined as having left a room in which the wireless speaker  1  is installed, whereby the volume value of the wireless speaker  1  is set to zero, and output of the audio signal from the wireless speaker  1  is stopped (S 114,  S 121 ).

Claim (Index 7):
A controller according to  claim 5 ,\n wherein the input characteristic measurement means is configured to sequentially measure, as the input characteristics, input waveforms of audio signals that are input to the microphone within the predetermined period, wherein the output characteristic reception unit is configured to sequentially receive, as the output characteristics, output waveforms of audio signals that are output from the wireless speaker within the predetermined period, and wherein the determination means is configured to determine that the listener is away from the vicinity of the wireless speaker when a delay time of the latest input waveform measured by the input characteristic measurement means with respect to the latest output waveform received by the output characteristic reception means is equal to or more than a predetermined length of time.
