Abstract:	In this paper, the wear of the suspensions in a speaker. This phenomenon can be characterized and seen as a variation of half inductance seen from the amplifier, because that value depends directly on the minimum and maximum excursion in the displacement of the moving coil. Having analyzed the possible cases of involvement of the shift from worn suspensions, has raised a board decision by which it is possible to diagnose the state of the suspension by measuring currents and voltages and calculation of half inductance seen from the amplifieR.
