Abstract: The excursion of a loudspeaker cone is estimated using a reference signal in one example, a primary signal, produced by a cone of a loudspeaker, is received and a reference signal produced simultaneously with the primary signal by the loudspeaker cone is received. The reference signal causes an excursion of the loudspeaker cone that is amplitude modulated by the excursion caused by the primary signal. An amplitude modulation of the reference signal is determined and an excursion of the loudspeaker cone is determined using the determined amplitude modulation.

Abstract: An audio output device is described comprising a speaker; an audio output circuit configured to receive a first audio signal and configured to supply the first audio signal and a second audio signal to the speaker, wherein the second audio signal comprises a higher frequency than the first audio signal; a microphone configured to receive an acoustic signal from the speaker in response to the first audio signal and the second audio signal and to convert the acoustic signal into a received audio signal and a determiner configured to determine a phase of a frequency component of the received audio signal corresponding to the second audio signal and to determine an excursion of the speaker by the first audio signal based on the phase.
