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 2):
A wireless speaker according to  claim 1 ,\n wherein the output characteristic measurement means is configured sea sequentially measure, as the output characteristic, output volume levels of audio signals that are output within the predetermined period from the wireless speaker, wherein the input characteristic reception unit is configured to sequentially receive, as the input characteristic, input volume levels of audio signals that are input within the predetermined period to the microphone included in the controller, and wherein the determination means is configured to determine that the listener is away from the vicinity of the wireless speaker when a ratio of the latest input volume level received by the input characteristic reception means to the latest output volume level measured by the output characteristic measurement means drops by a predetermined value or more.
