Abstract
Disclosed are a method and an apparatus for detecting a wearing state of an earphone, an earphone, and a storage medium. The method includes: obtaining a request for detecting the wearing state of the earphone; performing audio collection by a feedback microphone of the earphone to obtain a feedback audio signal; determining a frequency of the audio, and determining a target frequency with a power meeting a preset condition in the feedback audio signal based on the frequency and an audio collection parameter of the feedback microphone; performing a power spectrum analysis on the feedback audio signal to obtain a power spectrum of the feedback audio signal; determining target power information of the target frequency from the power spectrum; and in response to the target power information being not less than a maximum power threshold value set for the target frequency, determining that the wearing state is in-ear state.
