Abstract
The utility model provides a controllable diffuse reflection sound-absorbing device, comprising an outer frame, a sound absorber disposed in the outer frame and a diffusing device. The diffusing device comprises six diffusing plates; each diffusing plate comprises a movable shaft which penetrates the center of the diffusing plate vertically; two ends of the movable shaft are connected with the bottom and top of the outer frame respectively; the two sides of the central axis of each diffusing plate are connected with the top and bottom of the outer frame through movable locating pins; the outer frame is made of solid wood and is hollow and square in shape; one side of the outer frame is provided with at least two outer frame supporting plates arranged in a parallel manner; the sound absorber comprises a sound-absorbing cotton body, a sound-absorbing felt and textile sound-absorbing fabric and is disposed in the outer frame and between the diffusing plates and the outer frame supporting plates. The controllable diffuse reflection sound-absorbing device is simple in structure, easy to assemble and disassemble and elegant in appearance and realizes combination of reflection, diffusion and sound absorption. The diffusing plates can be rotated for different degrees for realizing the functions of diffusion, sound absorption and reflection.
Description
Technical field
The utility model relates to the sound absorber field, is specifically related to a kind of controlled diffuse reflection sound absorber.
Background technology
Along with the development of modern technologies, some electric equipments much all are furnished with sound absorber for fear of noise pollution, especially at recording room, home theater etc.But, sound absorber and reflection unit are combined as a whole, realize also rarely seen report of sound absorption, diffusion and the integrated device of reflex.
The utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of diffusion to combine with absorption, and the diffusion block angle is adjustable, easy installation simple in structure, the generous controlled diffuse reflection sound absorber of outward appearance.
For achieving the above object, technical scheme that the utility model adopts is as follows:
A kind of controlled diffuse reflection sound absorber is characterized in that, comprising: housing, place sound absorber and disperser in the described housing.
Described disperser comprises six diffusion blocks, and described diffusion block has the movable axis that vertically runs through its center, and described movable axis two ends are connected with bottom, the top of described housing respectively;
Described diffusion block central axis both sides are connected with top and the bottom of described housing by the activity orientation sheath respectively.
Described housing is the solid wood housing, is shaped as the square of hollow, and the one side has at least two housing gripper shoes that be arranged in parallel.
Described sound absorber is square, comprises the cotton body of sound absorption, baffle blanket and fabric sound absorption cloth, and it places in the described housing, between described diffusion block and described housing gripper shoe.
Controlled diffuse reflection sound absorber described in the utility model, its beneficial effect is:
Sound absorber and diffusion block are installed in the square frame, form a silencing means, simple in structure, easy installation, dismounting, outward appearance is generous; Sound absorber has acoustically effective, and diffusion block can spread, and will spread with sound absorption to combine, and simultaneously, diffusion block is rotatable, and angle is adjustable, and different rotation angle realizes diffusion, sound absorption, reflection function, and then the reverberation time in the control room.Be provided with highdensity sound absorber behind the reflecting plate, can effectively absorb the resonant acoustic wave after 250Hz eliminates the orienting reflex batten, absorb unfavorable reflection, standing wave and flutter echo.Can eliminate the nearly wall principal reflection that HIFI appreciates chamber, home theater, compact audio service depot.
Description of drawings
The picture that this description of drawings provides is used for auxiliary to further understanding of the present utility model, consists of the application's a part, does not consist of to improper restriction of the present utility model, in the accompanying drawings:
Accompanying drawing 1 is the perspective view of the controlled diffuse reflection sound absorber of the utility model.
Accompanying drawing 3 is the side structure schematic diagram of the controlled diffuse reflection sound absorber of the utility model.

The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific implementation method, be used for explaining the utility model in schematic enforcement of the present utility model and explanation, but not as to restriction of the present utility model.
As shown in drawings, the utility model discloses a kind of controlled diffuse reflection sound absorber, it comprises housing 1, places sound absorber 3 and disperser in the described housing, described disperser comprises six diffusion blocks 2, described diffusion block 2 has the movable axis 5 that vertically runs through its center, described movable axis 5 two ends are connected with bottom, the top of described housing respectively, and described diffusion block 2 central axis both sides are connected with top and the bottom of described housing by activity orientation sheath 6 respectively.Described housing 1 is the solid wood housing, is shaped as the square of hollow, and the one side has at least two housing gripper shoes 4 that be arranged in parallel.Described sound absorber 3 is square, comprises the cotton body 31 of sound absorption, baffle blanket 32 and fabric sound absorption cloth 33, and baffle blanket is Chopped Strand Mat, and it places in the described housing, between described diffusion block 2 and described housing gripper shoe 4.
Described six diffusion blocks can rotate by 360 degree, when its whole rotations are extremely vertical with housing, realize sound absorption function; When whole rotations to tilting, when angled with housing, realizing reflection function; When about three diffusion blocks tilt, direction not simultaneously, realize diffusion function.Utilize different effects to come the reverberation time in the control room.
Controlled diffuse reflection sound absorber described in the utility model, its beneficial effect is:
Sound absorber and diffusion block are installed in the square frame, form a silencing means, simple in structure, easy installation, dismounting, outward appearance is generous; Sound absorber has acoustically effective, and diffusion block can spread, and will spread with sound absorption to combine, and simultaneously, diffusion block is rotatable, and angle is adjustable, and different rotation angle realizes diffusion, sound absorption, reflection function, and then the reverberation time in the control room.Be provided with highdensity sound absorber behind the reflecting plate, can effectively absorb the resonant acoustic wave after 250Hz eliminates the orienting reflex batten, absorb unfavorable reflection, standing wave and flutter echo.Can eliminate the nearly wall principal reflection that HIFI appreciates chamber, home theater, compact audio service depot.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, all will change on the specific embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
