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 12):
A program readable by a computer, for causing the computer to function as a controller configured to remotely operate a wireless speaker configured to reproduce and output an audio signal,\n the controller including:\n a microphone; \n input characteristic measurement means for sequentially measuring input characteristics of audio signals that are input to the microphone within a predetermined period; \n output characteristic reception means for sequentially receiving, from the wireless speaker, output characteristics of audio signals that are output from the wireless speaker within the predetermined period; \n determination means for comparing the latest output characteristic received by the output characteristic reception means and the latest input characteristic measured by the input characteristic measurement means, and determining, from a result of the comparison, whether a listener owning the controller is away from vicinity of the wireless speaker; and \n output stop instruction transmission means for transmitting, to the wireless speaker, an output stop instruction for stopping output of an audio signal when the determination means determines that the listener is away, from the vicinity of the wireless speaker.
