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 1):
A wireless speaker, which is configured to reproduce and Output an audio signal in accordance with remote operation performed on a controller, the wireless speaker comprising:\n output characteristic measurement means for sequentially measuring output characteristics of audio signals that are output within a predetermined period; input characteristic reception means for sequentially receiving, from the controller, input characteristics of audio signals that are input within the predetermined period to a microphone, which is included in the controller; determination means for comparing the latest output characteristic measured by the output characteristic measurement means and the latest input characteristic received by the input characteristic reception means, and determining, from a result of the comparison, whether a listener owning the controller is away from vicinity of the wireless speaker; and control means for stopping output of an audio signal when the determination means determines that the listener is away from the vicinity of the wireless speaker.
