Abstract: A method for input operation control, a terminal device, and an earphone are provided. The method includes the following. An input operation on an exhaust hole defined in an audio processing device is received. A frequency-response curve associated with an acoustic structure of the audio processing device is acquired according to an audio signal currently played by the audio processing device. The input operation is recognized according to the frequency-response curve, and a control instruction corresponding to the input operation is generated. A terminal device in communication with the audio processing device is controlled according to the control instruction.

Abstract: A method for processing audio signal, an electronic device, and an earphone are provided. The method includes the following. An input operation of a user performed on an earphone is received, and an acoustic echo impulse response at a position of the user's ear canal where the earphone currently stays is determined according to an audio signal currently played by the earphone and a vibration signal generated by the input operation. A directive instruction corresponding to the input operation is identified at least according to the acoustic echo impulse response. An electronic device in communication with the earphone is controlled to execute a corresponding operation for a preset application in the electronic device according to the directive instruction.
