Abstract
The utility model discloses a variable sound absorber. The variable sound absorber comprises a plurality of rotatable regular triangular prism sound absorbing blocks which are arranged in parallel, wherein rotating centers are located on the same straight line; and three cylinders of each regular triangular prism sound absorbing block are three sound absorbing surfaces with different absorption rates. According to the variable sound absorber, each regular triangular prism sound absorbing block is provided with three sound absorbing surfaces which can be switched flexibly, so that the variable sound absorber is more suitable for an occasion with reverberation environmental change and can effectively absorb high-frequency, medium-frequency and low-frequency sound waves according to different sound effects.
Description
Technical field
The utility model relates to a kind of suspended absorber.
Background technology
Suspended absorber be mainly applicable to stadiums, the performing art Room, opera house, multi function hall, etc. large space or strong noise workshop and the more outstanding place of reverberation sound, generally look the sound absorption material fixed installation that environment different choice is different, or adopt liftable bilateral structure, for the occasion of reverberation environmental change, this obviously can not satisfy the demand.
Summary of the invention
The utility model, for the above-mentioned defect of prior art, provides a kind of adjustable absorbers that can change flexibly sound absorption face.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
Adjustable absorbers, comprises several discharge, rotatable regular triangular prism sound absorption blocks side by side, and center of rotation is positioned on straight line, and three cylinders of described regular triangular prism sound absorption block are three different sound absorption faces of absorptivity.
Further, described regular triangular prism sound absorption block is fixed on the rolling bearing in housing by RC turning cylinder.
Further, three angles of regular triangular prism sound absorption block are provided with steel ball lock pin, effect be location adjustable absorbers towards.
Further, on described turning cylinder, motor is installed.
Further, the lumen loading acoustical cotton of described regular triangular prism sound absorption block.
Further, described three sound absorption faces that absorptivity is different are respectively fire-retardant entrant sound fabric faced, Pierced Aluminum Plank facing and three-dimensional wave-shape board facing; Fire-retardant entrant sound fabric faced mainly regulates the sound of medium-high frequency section; Pierced Aluminum Plank face mainly regulates the sound of Mid Frequency; Three-dimensional wave-shape board face mainly regulates the sound of low-frequency range, and has the effect of sound dispersion.
The utlity model has three sound absorption faces, and three sound absorption faces can flexible conversion, be more applicable for the occasion of reverberation environmental change, can be effectively according to the different senior middle school's low-frequency sound waves that absorb of acoustics.
[accompanying drawing explanation]
Accompanying drawing 1 is top view of the present utility model;
Accompanying drawing 2 is regular triangular prism sound absorption block sectional drawings of the present utility model.
[specific embodiment]
Below in conjunction with the specific embodiment, the utility model is described in further detail.
Adjustable absorbers as shown in Figure 1, comprises three discharge, rotatable regular triangular prism sound absorption blocks 1 side by side, and center of rotation is positioned on straight line.Described regular triangular prism sound absorption block 1 is fixed on the rolling bearing 2.1 in housing 2 by RC turning cylinder 1.1.Three angles of regular triangular prism sound absorption block 1 are provided with steel ball lock pin 1.2, effect be location adjustable absorbers towards.
As shown in Figure 2, three of regular triangular prism sound absorption block 1 cylinders are three different sound absorption faces of absorptivity.Described three sound absorption faces that absorptivity is different are respectively fire-retardant entrant sound fabric faced 1.3, Pierced Aluminum Plank facing 1.4 and three-dimensional wave-shape board facing 1.5; The main sound that regulates medium-high frequency section of fire-retardant entrant sound fabric side 1.3; The main sound that regulates Mid Frequency of Pierced Aluminum Plank face 1.4; Three-dimensional wave-shape board face 1.5 mainly regulates the sound of low-frequency range, and has the effect of sound dispersion.The lumen loading acoustical cotton 1.6 of regular triangular prism sound absorption block 1.
When regular triangular prism sound absorber of the present utility model forwards co-planar locations as shown in Figure 1 to, coplanar that of each regular triangular prism sound absorber sound absorption identity distance is from leveling off to zero.
Below the utility model is described in detail, the above, be only the preferred embodiment of the utility model, do not limit the utility model practical range, be allly according to the application's scope, to do impartial change and modify, all should still belong in the utility model covering scope.
