ABSTRACT:
Each loudspeaker (10, 10′) comprises means, e.g. of the Bluetooth type, for establishing a wireless interface with every other loudspeaker of the system. The network configures itself automatically by each loudspeaker searching for the other loudspeakers with which a wireless link can be established directly, by drawing up a table of mutual visibilities, and, on the basis of said table, defining a hierarchical network topology. One of the loudspeakers is designated as the network head so as to be capable of searching for and setting up a wireless link with a remote peripheral capable of transmitting a coded audio signal (A2DP) and/or a control signal (AVRCP). The other loudspeakers receive audio signals sent to them encapsulated in messages that include routing data, either directly, or after said signals have been relayed via another loudspeaker.
