Abstract
The invention relates to an acoustic loudspeaker which includes a magnetic field source. A mobile apparatus includes a diaphragm and a first winding capable of allowing passage of an electrical current representing the sound signal to be generated and of interacting with the magnetic field. The acoustic loudspeaker includes a second winding, both terminals of which are connected by a resistive component. Both terminals of the second winding are electrically isolated from the terminals of the first winding.
