MULTICHANNEL AUDIO PLAYBACK Russian patent published in 2017 - IPC H04S5/00 G10L19/08 

FIELD: acoustics.

SUBSTANCE: invention relates to playback of multichannel audio and is used, in particular, in a home theater/surround sound playback system using wireless speakers units. Multichannel audio playback system comprises an audio playback module, which generates audio signals for multiple audio channels. Multiple interchangeable speakers units comprises a storage battery and an audio converter to playback an audio signal. Charging unit is connected to a specific audio channel and has a charging source, which can charge a storage battery connected to a speaker unit. Binding circuit can bind the speaker unit when it is connected to the charging unit with the first audio channel. System can continuously associate specific channels with charging units (or passive bases of speakers, which can not perform charging), and the interchangeable speaker units can be adapted depending on their connection. This approach may enable to perform charging a speaker unit (possibly, a wireless one) just by replacing this speaker unit with one of those connected to the charging unit.

EFFECT: technical result is increased flexibility and easier operation by reducing the need for wire connections.
