摘要： 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.
