Abstract

The invention discloses a method and a system for directionally enhancing sound. The method comprises the following steps: detecting a sound source which initiates a control instruction; positioning the sound source; adjusting the signal channel delay of each loudspeaker in the array loudspeaker according to the relative position relationship between the sound source and the array loudspeaker, sothat the sound wave of each loudspeaker reaching the sound source generates in-phase wavefront interference. The system comprises a directional enhanced sound control device and a terminal, wherein the directional enhanced sound control device is connected with the terminal. The problem of unclear acquired sound caused by non-centralized propagation of sound energy is solved, and centralized propagation of the sound energy in a specific direction is realized so as to meet the requirement of improving the sound sharpness in different scenes.

Description

technical field [0001] The present application relates to the technical field of sound wave processing, and in particular to a method and system for directional enhancement of sound. Background technique [0002] In recent years, sound wave interference technology has been widely used in the field of sports sound reinforcement. The typical example is the application of line array speakers. In the prior art, the linear arrays of TV line array speakers are closely spaced, because the linear arrays interfere with each other, resulting in The sound quality of the TV line array speakers is extremely poor. [0003] The inventor of the present application found that the use of the above-mentioned speakers has the following technical problems: first: the interference main lobe direction of the prior art TV line array speakers is relatively fixed and cannot be automatically changed according to the scene; Experience the effect. [0004] Therefore, it is very important to provide a ...
