Abstract

The present application provides a directional sound emitting device, method and AR equipment. The directional sound generating device includes a main speaker and a noise canceling speaker for sounding; the frequency of the sound wave emitted by the noise canceling speaker is the same as that of the sound wave emitted by the main speaker, and the phase of the sound wave emitted by the sound canceling speaker is opposite to that of the sound wave emitted by the main speaker in the direction of the sound cancellation. The directional sound emitting device provided by this application, by setting the main speaker to emit sound, and setting the noise canceling speaker, so that the noise canceling speaker points to the sound canceling direction, and makes the frequency of the sound wave emitted by the noise canceling speaker and the main speaker be the same, while the sound wave emitted by the noise canceling speaker and the main speaker is in the sound canceling direction. The phases of the sound waves are opposite, and the noise-cancelling speakers in the sound-cancelling direction can weaken or cancel the sound waves from the main speaker, and then only emit sound in the specified direction to achieve directional sound generation.

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...
