1. An audio control method, which is applicable to a display screen configured with M speakers, wherein, M is an integer greater than or equal to 2, and the method comprises:
obtaining a sound image coordinate of a sound object relative to the display screen;
determining N speakers from the M speakers as loudspeakers according to the sound image coordinate and position coordinates of the M speakers relative to the display screen, wherein N is an integer less than or equal to M;
determining output gains of the N loudspeakers according to distances between the N loudspeakers and a viewer of the display screen and sound attenuation coefficients; and
calculating output audio data of the sound object in the display screen according to audio data of the sound object and the output gains of the N loudspeakers, and controlling the M speakers to play the output audio data.
