Earphone recognition method and apparatus, earphone control method and apparatus, and earphone

An earphone recognition method, comprising:

• an acquisition step:
• when a user wears the earphone comprising a piezoelectric film sensor and a piezoelectric signal processor, the piezoelectric film sensor comprises a signal processing circuit and an audio control circuit, acquiring left and/or right ear structure information, collected by the earphone, of the user, wherein the acquisition step specifically comprises, when the user wears the earphone, acquiring a pressure signal on the earphone receiver through the signal processing circuit, and converting the pressure signal into a level signal;
• and sampling, quantifying and encoding the level signal by the piezoelectric signal processor to acquire a spectrum signal, and using the spectrum signal as the left and/or right ear structure information;
• and
• a determining step:
• determining whether the user correctly wears the earphone according to whether the left and/or right ear structure information matches left and/or right ear structure information acquired when the user correctly wears the earphone for the first time, wherein when the user does not correctly wear the earphone, sending a sound channel switching signal to the audio control circuit by the signal processing circuit to allow the audio control circuit to switch the sound channels in the earphone receiver.
