Summary:A displacement estimation system for estimating cone displacement of a loudspeaker may include an electrical circuit including at least one non-linear component being coupled to a mechanical circuit including at least one non-linear component, and a controller programmed to determine the cone displacement of the loudspeaker based on the at least one non-linear component by using a discrete domain transfer function of a measured current of the electrical circuit, and transmit the displacement to a corrector to correct distortion of an audio signal due to the displacement.
