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.

Claim (Index 1):
A method for processing audio signal, comprising:\n receiving an input operation of a user performed on an earphone; determining an acoustic echo impulse response at a position of the user's ear canal where the earphone currently stays according to an audio signal currently played by the earphone and a vibration signal generated by the input operation; identifying a directive instruction corresponding to the input operation at least according to the acoustic echo impulse response; controlling an electronic device in communication with the earphone to execute a corresponding operation for a preset application in the electronic device according to the directive instruction, the preset application being an application corresponding to the audio signal currently played by the earphone; and wherein identifying the directive instruction corresponding to the input operation at least according to the acoustic echo impulse response comprises:\n acquiring, in a preset time period, a response parameter of the acoustic echo impulse response, wherein the response parameter at least contains a response position and response times; and \n identifying the directive instruction corresponding to the input operation according to the response parameter.
