Kind Code:
A1
Abstract:
An audio processing method, applicable to an electronic device. The method comprises: obtaining an audio signal required to be output by a loudspeaker (101); performing bass boost processing on the audio signal to obtain a bass boosted audio signal (102); predicting a diaphragm displacement generated by output of the bass boosted audio signal by the loudspeaker, and determining whether the predicted diaphragm displacement is greater than a preset displacement (103); and if yes, performing gain control on the bass boosted audio signal to enable the diaphragm displacement generated by output of the bass boosted audio signal subjected to gain control by the loudspeaker to be less than or equal to the preset displacement (104).
