Audio calibration method and device

An audio calibration device, applied to calibrate consistency of a first loudspeaker and a second loudspeaker in a headphone by using an audio calibration method;

• wherein the audio calibration method is executed by a processor built in the headphone which comprises the first loudspeaker, the second loudspeaker, a first microphone and a second microphone, and the audio calibration method comprises:
• transmitting an audio calibration signal to the first loudspeaker and the second loudspeaker such that the first loudspeaker and the second loudspeaker generate sound signals, wherein the first loudspeaker and the second loudspeaker are disposed opposite to each other;
• determining first loudspeaker sound information through a sound signal generated by the first loudspeaker and acquired by the first microphone and a sound signal generated by the first loudspeaker and acquired by the second microphone, wherein the first microphone and the second microphone are disposed opposite to each other;
• determining second loudspeaker sound information through a sound signal generated by the second loudspeaker and acquired by the first microphone and a sound signal generated by the second loudspeaker and acquired by the second microphone;
• and
• determining a calibration parameter of the first loudspeaker or a calibration parameter of the second loudspeaker according to the first loudspeaker sound information and the second loudspeaker sound information,
• wherein determining the calibration parameter of the first loudspeaker or the calibration parameter of the second loudspeaker according to the first loudspeaker sound information and the second loudspeaker sound information comprises:
• if a difference value between a sensitivity of the first loudspeaker sound information and a sensitivity of the second loudspeaker sound information is within a preset range, calculating a difference value between the first loudspeaker sound information and the second loudspeaker sound information;
• and
• taking the difference value between the first loudspeaker sound information and the second loudspeaker sound information as the calibration parameter of the first loudspeaker or the calibration parameter of the second loudspeaker.
