Abstract
The present disclosure discloses a method and apparatus for directional sound emission of an audio device, and an audio device. The method includes: by using the spherical microphone array, determining a spatial position of a sound-emission sound source of a user; according to a relationship among the spatial position of the sound-emission sound source of the user, a center position of the audio device and an opening position of the loudspeaker, determining a horizontal compensatory angle and a vertical compensatory angle of the opening direction of the loudspeaker relative to the spatial position of the user; and adjusting the opening direction of the loudspeaker, so that the horizontal compensatory angle and the vertical compensatory angle are made to be zero.
