Abstract
A method for determining and mitigating over-excursion of an internal mass of an under-damped electromechanical transducer may include transforming an electrical playback signal to an estimated displacement signal, based on the estimated displacement signal, determining an estimated over-excursion of the internal mass responsive to the electrical playback signal, and limiting, based on the estimated over-excursion, an electrical driving signal derived from the electrical playback signal and for driving the electromechanical transducer in order to mitigate over-excursion of the internal mass.
