Abstract

The invention provides a directional sounding device and method and AR equipment. The directional sounding device comprises a main loudspeaker used for sounding and a silencing loudspeaker; the frequency of sound waves emitted by the silencing loudspeaker is the same as that of sound waves emitted by the main loudspeaker, and the phase of the sound waves emitted by the silencing loudspeaker is opposite to that of the sound waves emitted by the main loudspeaker in the silencing direction. According to the directional sounding device, the main speaker is arranged for sounding, and the silencingloudspeaker is arranged, the silencing loudspeaker points to the silencing direction; the sound attenuation loudspeaker and the main loudspeaker emit sound waves with the same frequency, and the soundattenuation loudspeaker and the main loudspeaker emit sound waves with opposite phases in the sound attenuation direction, so that the sound attenuation loudspeaker in the sound attenuation directioncan weaken or offset the sound waves emitted by the main loudspeaker, and then sound is emitted only in the specified direction to realize directional sound emission.

Description

technical field [0001] The present application belongs to the field of electronic technology, and more specifically relates to a directional sound emitting device, a directional sound emitting method and electronic equipment. Background technique [0002] Augmented Reality (AR for short), AR (English: Augmented Reality) is the abbreviation of Augmented Reality. Augmented reality technology, also known as augmented reality, is a technology that promotes the integration of real world information and virtual world information content. It overlaps the real environment and virtual objects and can exist in the same picture and space at the same time. , and be perceived by human senses, so as to achieve a sensory experience beyond reality, that is, to achieve "enhancement" of the real world. [0003] In order to play sound, speakers or earphones are generally installed on current AR devices. When using earphones, due to the discomfort that may be caused by wearing them for a long...
