Embodiment Construction

[0018] figure 1 The hardware schematic structure of the audio effector based on the sound beam reflection of the acoustic parametric array is shown. The audio effector based on acoustic parametric array sound beam reflection is composed of a sound source 1, an acoustic parametric array speaker array 2, an acoustic beam reflector 3, an acoustic beam reflector motion driving part 4 and an acoustic beam reflector motion control part 5. The sound source 1 is a common sound source such as MP3, computer, MP4, radio, tape recorder, etc., and the audio signal generated by it is used as the input signal of the acoustic parametric array loudspeaker array 2 . The acoustic parametric array loudspeaker array 2 may be composed of single or multiple acoustic parametric array loudspeakers, and each acoustic parametric array loudspeaker generates an audio sound beam with high directivity propagation. Adjust the installation position and direction of each acoustic parametric array loudspeaker ...

Abstract

A sound frequency special effect editor based on acoustic parametric array acoustic beam reflection is composed of a sound source, an acoustic parametric array speaker array, an acoustic beam reflection body, an acoustic beam reflection body moving component and an acoustic beam reflection body motion control component. According to the sound frequency special effect editor based on the acoustic parametric array acoustic beam reflection, local transmission and reflection characteristics of high directivity acoustic beams generated by an acoustic parametric array are utilized, three dimensional multibeam dynamic mixed audio effects are achieved, and completely novel sound frequency special effect experience can be brought for the audience.

Description

technical field [0001] An audio special effect device, in particular to a device for realizing stereo audio special effects by utilizing the reflection characteristic of a highly directional sound beam generated by an acoustic parameter array. Background technique [0002] Traditional audio special effects mainly realize audio special effects through sound effect processing circuits or digital signal processing means. The sound effect processing circuit is mainly used to realize audio special effects by means of hardware. For example, a two-channel stereo sound processing circuit can realize stereo three-dimensional surround effects in occasions such as computers, TVs, and listening spaces that do not require high audio special effects. Multi-sound The channel sound effect processing circuit can realize more natural, higher fidelity, better sound quality and stronger surround effect. With the development of digital signal processing technology, audio special effect processi...
