Document Type and Number:
WIPO Patent Application WO/2021/014691
Kind Code:
A1
Abstract:
[Problem] To enable a wireless speaker to join a group with easy operation in a wireless audio system in which one or more wireless speakers form a group, and audio data is reproduced group by group. [Solution] When accepting a group joining operation from a user, a wireless speaker 1 transmits a group joining request to any master if the wireless speaker has not yet joined any group, and joins a group to which the master belongs. If the wireless speaker has already joined any group, the wireless speaker transmits a group withdrawal request to a master of this group to withdraw from the group, then transmits a group joining request to any master other than the transmission destination of the group withdrawal request, and joins a group to which this master belongs. If audio data is being reproduced in the newly joined group, the wireless speaker immediately outputs the reproduced data.
