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 4):
A wireless speaker according to  claim 2 , further comprising resumption instruction reception means for receiving a resumption instruction from the controller,\n wherein the control means is configured to:\n store a set value of a sound volume as a resumption level when the determination means determines that the listener is away from the vicinity of the wireless speaker, and stop the output of an audio signal by changing the set value of the sound volume to a zero level; and \n change the set value of the sound volume from the zero level to the resumption level when the resumption instruction reception means receives the resumption instruction within a predetermined time-out time since the stop of the output of an audio signal, and stop the reproduction of audio signals when the resumption instruction is not received.
