Abstract

The invention relates to the technical field of architectural acoustics, in particular to a diffuser, a sound field diffusion system and a private cinema. The diffuser provided by the present invention is used in a small audio-visual space, and includes a bottom plate and a diffusion protrusion connected to the bottom plate, and the distance from the highest point of the diffusion protrusion to the bottom plate is 55 mm to 65 mm. Aiming at the characteristics of sound wave propagation in small audio-visual spaces, the diffuser provided by the present invention can effectively diffuse sound waves with a frequency above 722 Hz, thereby making the sound in the small audio-visual space round, with a strong three-dimensional effect and good sound quality, thereby improving people's audio-visual experience and making it more It can meet people's spiritual needs, and people can enjoy high-quality music feasts without going to grand theaters or concert halls. In addition, the installation of the diffuser provided by the present invention can increase the best listening area in a small-sized equivalent space, which is called the "emperor area" by people, so that more people can enjoy good sound quality.

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...
