Title: AUDIO SIGNAL SOUND DIFFUSION SYSTEM
Abstract:
The present invention relates to an audio signal sound diffusion system for diffusing, e.g., alarm signals, pre-recorded signals and microphone signals over wide areas. According to one of its aspects, the present invention relates to an audio signal sound diffusion system characterised in that it comprises: at least one diffuser (35a-38a, 35b-38b); at least one amplifier (31-34) connected to said diffuser (35a-38a, 35b-38b); a generation circuit (27) for generating at least one audio signal connected to said amplifier (31-34); a control circuit (10) for controlling said sound diffusion system adapted to detect the malfunctions of said diffusion system and to generate a status alarm (14) of said diffusion system; connection means (17, 40) adapted to connect said control circuit (10) to a management system; said control circuit (10) is adapted to send to said management system at least one status alarm (14) of said sound diffusion system.
