Abstract:
[Problem] In the case where an audio signal of the same source is output from a plurality of speakers, the speakers are adjusted so that the audio signals become optimal at a listening position. [Solution] Processing in which an audio signal output from a wireless speaker  1  is collected by a microphone of a controller  2  carried by a listener and a delay time is measured that is the difference between an output time of the audio signal from the wireless speaker  1  and an input time of the audio signal to the microphone of the controller  2  is performed on a plurality of the wireless speakers  1  that output an audio signal of the same source, and the delay times of the audio signals from these respective wireless speakers  1  are measured. Output timings of these respective wireless speakers  1  are adjusted on the basis of these delay times.

Claim (Index 4):
A wireless audio system according to  claim 1 ,\n wherein the plurality of wireless speakers each further include:\n beacon signal transmission means for transmitting a beacon signal including identification information on an own wireless speaker; and \n received radio wave information notification means for receiving the beacon signal including identification information designated in a radio wave detection instruction received from the controller, detecting a received radio wave strength of the beacon signal, and notifying the controller of the detected received radio wave strength, in accordance with the radio wave detection instruction, and \n wherein the controller further includes:\n received radio wave strength detection means for receiving a beacon signal transmitted from each of the plurality of wireless speakers and detecting a received radio wave strength of the beacon signal; \n reference coordinate identification means for transmitting, to a first wireless speaker for which a received radio wave strength is detected by the received radio wave strength detection means among the plurality of wireless speakers, a radio wave detection instruction containing designation of identification information on a second wireless speaker for which a received radio wave strength is detected by the received radio wave strength detection means, acquiring a received radio wave strength of the second wireless speaker detected by the first wireless speaker from the first wireless speaker, and identifying a reference coordinate system identified by relative positions of the controller, the first wireless speaker, and the second wireless speaker based on the received radio wave strength of each of the first and second wireless speakers detected by the received radio wave strength detection means and the received radio wave strength of the second wireless speaker detected by the first wireless speaker; \n position identification means for performing, for each of the plurality of wireless speakers excluding the first and second wireless speakers, processing of: transmitting, to each of the first and second wireless speakers, a radio wave detection instruction containing designation of identification information on a wireless speaker being a measurement target for which a received radio wave strength is detected by the received radio wave strength detection means; acquiring received radio wave strengths of the wireless speaker being the measurement target detected by the first and second wireless speakers from the first and second wireless speakers; and identifying a position of the wireless speaker being the measurement target based on the received radio wave strength of the wireless speaker being the measurement target detected by the received radio wave strength detection means, the received radio wave strengths of the wireless speaker being the measurement target detected by the first and second wireless speakers, and the reference coordinate system identified by the reference coordinate identification means; \n installation state determination means for determining installation states of the plurality of wireless speakers with respect to the controller based on the reference coordinate system identified by the reference coordinate identification means and positions of the plurality of wireless speakers excluding the first and second wireless speakers identified by the position identification means; and \n output mode determination means for determining an audio signal output mode of audio signals to be output from the plurality of wireless speakers based on the installation states determined by the installation state determination means.
