Abstract (en)
[origin: WO2011117557A2] The method of loudspeaker control comprises: a step (215) of emitting a pulse on an electrical link with the loudspeaker, a step (220) of measuring the electrical resistance on said link, a step (225) of determining the state of the loudspeaker as a function of said resistance and a step (230, 235) of triggering a corrective action, as a function of the state thus determined of the loudspeaker. In embodiments, the method comprises, furthermore: a step of associating a plurality of amplification systems with various subsets of the plurality of loudspeakers, a step of assigning different signals to be emitted by various loudspeakers for each of a plurality of control signals, a step of storing parameters representative of said signals to be emitted, in each amplification system on receipt of a control signal common to the various amplification systems, the amplification systems bringing about the emission of the different signals to said loudspeakers, said corrective action comprising a storage of parameters representative of the state of said loudspeaker.
