Abstract

The present invention discloses an indoor reverberation adjustment system, comprising a fixed frame, a transmission device, and a plurality of inverted blades, wherein a lower end of the inverted blade is mounted on the transmission device, and an upper end of the inverted blade is rotatably coupled to the fixed frame; the inverted blade include a rotating frame, a first reflector, a second reflector, and a sound absorbing panel, the rotating frame has three mounting surfaces, and the first reflector, the second reflector, and the sound absorbing panel are respectively mounted on the three mounting surfaces, and form a first triangular prism body, the first reflector, the second reflector, and the sound absorbing panel are three facets of the first triangular prism respectively. The indoorreverberation adjustment system adopts an electric adjustable flip type structure, and can be switched to a specific sound absorbing reflective material after each flipping, thereby achieving the purpose of adjusting reverberation time according to space utilization.

Description

technical field [0001] The invention relates to the field of audio, in particular to an indoor reverberation adjustment system. Background technique [0002] The materials of existing reverberation products are all of a single structure with a fixed sound absorption coefficient. Once used indoors, the reverberation time is fixed, and the listening conditions cannot be changed according to the function of use. Contents of the invention [0003] The object of the present invention is to provide an indoor reverberation adjustment system. The indoor reverberation adjustment system adopts an electrically adjustable flip structure, which can be switched to a specific sound-absorbing reflective material after each flip, so that the reverberation can be adjusted according to the space use. The purpose of ringing time. [0004] Its technical scheme is as follows: [0005] The indoor reverberation adjustment system includes a fixed frame, a transmission device, and a plurality of ...
