Abstract
The present invention relates to an acoustic signal supply circuit of at least one loudspeaker (HP) incorporating a filtering device of the resonance peak of said at least one loudspeaker (HP) occurring at a given frequency, characterized in that the filtering device of the resonance peak of said at least one loudspeaker (HP) is incorporated either into the first instrumentation ground circuit or in the feedback loop, this filtering device being purely electrical in the form an impedance incorporated in the first instrumentation ground circuit or in the feedback loop, the impedance parameters being predetermined as a function of the resonance peak to be filtered of said at least one loudspeaker (HP).
