Abstract

The invention relates to the technical field of architectural acoustics, in particular to a diffusion body, a sound field diffusion system and a private cinema. The diffuser body comprises a bottom plate and at least one groove group formed in the bottom plate; each groove group comprises a first groove, two second grooves, two third grooves and two fourth grooves; and the depth of each first groove is less than the depth of the corresponding second groove, the depth of each second groove is greater than the depth of the corresponding third groove, and the depth of each third groove is greaterthan the depth of the corresponding fourth groove. In one of the groove group, the first groove, one second groove, one third groove, one fourth groove, the other fourth groove, the other third groove and the other second groove are sequentially and evenly formed at intervals from the first side of the bottom plate to the second side of the bottom plate. According to the diffuser body, aiming atthe characteristic of sound wave propagation of a small audio-visual space, the sound of the small audio-visual space is made to be mellow and full, the stereoscopic sensation is high, the sound quality is good, and the audio-visual feeling of people is improved accordingly.

Description

technical field [0001] The invention relates to the technical field of architectural acoustics, in particular to a diffuser, a sound field diffusion system and a private cinema. Background technique [0002] The diffuser is an arrangement adopted to improve the sound field diffusion performance. The diffuser diffuses multiple sound fields to make the sound field uniform, so that the indoor sound is uniform and round, which can improve people's audio-visual effect. [0003] In terms of size, an audio-visual space with a volume of less than 500 cubic meters is generally called a small audio-visual space, such as: private theater, KTV, piano room, studio, HIFI room, etc. With the improvement of people's living standards, people's pursuit of spiritual life is getting higher and higher, and people's requirements for sound quality in private theaters, KTV and other places are getting higher and higher. [0004] However, there is currently no diffuser specially provided for small...
