The purpose of this paper is to present a new model to study intern-turn short circuit faults in a dynamic loudspeaker. The loudspeaker is modeled by using classical voice coil parametric model attached to a mechanical piston, and the equations are modified to take into account the voice coil inter-turn faults. The loudspeaker model is global and can work in both normal and fault conditions due to a fictitious resistance in the winding circuit. Various simulation results have been presented indi...
