Abstract

The invention provides a directional sound generation method and device and electronic equipment, and the method and device are used for the electronic equipment comprising a plurality of loudspeakers. The method comprises the steps: transmitting a first audio signal to the sound generation loudspeaker in the plurality of loudspeakers; transmitting a second audio signal with the phase being opposite to the phase of the first audio signal to the loudspeaker at at least one side of the periphery of the sound generation loudspeaker, so as to counteract the sound scattered by the sound generation loudspeaker to at least one side of a target sound generation direction. Therefore, the method can achieve the real directional generation of sound.

Description

technical field [0001] The present invention relates to the technical field of audio output control, in particular to a directional sounding method, device and electronic equipment. Background technique [0002] Most of the existing directional sounding methods achieve the purpose of directional sounding by adjusting the direction of the horn. However, the transmission characteristics of sound waves determine that the sound emitted by the horn cannot only propagate along a straight line, and will also be scattered to other directions. Therefore, mechanically adjusting the orientation of the horn cannot achieve true directional sound emission. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a method, device and electronic equipment for directional sound generation, so as to improve the above problems. [0004] In order to achieve the above object, a preferred embodiment of the present invention provides a method for d...
