Abstract
In accordance with embodiments of the present disclosure, a controller configured to be coupled to an audio transducer, may be further configured to receive an audio input signal, calculate a displacement compensation signal in a displacement domain of the audio transducer based on the audio input signal, convert the displacement compensation signal from the displacement domain into a voltage compensation signal in a voltage domain, and apply the voltage compensation signal to the audio input signal, or a derivative thereof, to minimize overexcursion of the audio transducer.
