Earphone wearing state detection method and apparatus, and earphone and storage medium

An earphone wearing state detection apparatus, comprising:

• a detection request acquisitor configured to acquire a detection request for a wearing state of an earphone;
• a feedback audio signal determiner configured to perform audio collection through a feedback microphone of the earphone to obtain a feedback audio signal;
• a target frequency band determiner configured to determine a frequency of an audio and based on the frequency, determine a target frequency band in the feedback audio signal in which the frequency range meets a preset condition;
• a power spectrum determiner configured to determine a power spectrum of the feedback audio signal;
• an energy magnitude indicator value determiner configured to determine, based on the power spectrum, an energy magnitude indicator value of the feedback audio signal within the range of the target frequency band;
• a wearing state determiner configured to determine that the wearing state of the earphone is an in-ear state if the energy magnitude indicator value is not lower than a preset minimum energy threshold corresponding to the in-ear state.

An earphone, comprising:

• a processor and a memory, wherein the memory stores a plurality of instructions;
• wherein the processor is configured to load the instructions from the memory to execute an earphone wearing state detection method comprising:
• acquiring a detection request for a wearing state of an earphone;
• performing audio collection through a feedback microphone of the earphone to obtain a feedback audio signal;
• determining a frequency of an audio and based on the frequency, determining a target frequency band in the feedback audio signal in which a frequency range meets a preset condition;
• determining a power spectrum of the feedback audio signal;
• based on a power spectrum, determining an energy magnitude indicator value of the feedback audio signal within a range of the target frequency band;
• if the energy magnitude indicator value is not lower than a preset minimum energy threshold corresponding to an in-ear state, determining that the wearing state of the earphone is the in-ear state.
