Abstract
The invention relates to a method implementing at least one loudspeaker comprising at least one module suitable for generating a value representative of an internal operation of the loudspeaker, and a memory unit for storing an alarm criterion relative to the generated value, and control software for controlling the loudspeaker. The method further comprising the steps of the module produces a value representative of the internal operation of the loudspeaker, the loudspeaker compares the generated value and the alarm criterion, and the loudspeaker emits a sound or visual signal if the result of the comparison indicates that the generated value fulfills the alarm criterion.
