Abstract
Present invention is disclosed a kind of acoustic(al)absorbent, the perforated plate (1) being connected including housing (5) and with the housing (5), it also includes sound-absorbing component (2), and the sound-absorbing component (2) is formed by least two material interlaced arrangements with different acoustic properties.The interface (6) of described two different acoustical materials is serrated.The sound-absorbing component (2) includes sound absorption wedge (3) and acoustical cotton (4), and the acoustical cotton (4) is filled between the sound absorption wedge (3) and the perforated plate (1).The sound-absorbing component (2) can be arranged to multilayer.The acoustic(al)absorbent of the present invention has more preferably sound-absorbing effect.
Description
Technical field
The present invention relates to a kind of acoustic(al)absorbent.
Background technology
The general surface of traditional acoustic(al)absorbent uses perforated plate, and single acoustical cotton is filled in inside, and its sound-absorbing is inefficient.
The content of the invention
It is an object of the invention to for drawbacks described above of the prior art, there is provided a kind of more efficient sound-absorbing of sound-absorbing
Body.
For achieving the above object, present invention employs following technical scheme：One kind, including housing and with the housing
Connected perforated plate, the acoustic(al)absorbent also include sound-absorbing component, and the sound-absorbing component has different acoustic properties by least two
Material interlaced arrangement form.
In addition, the present invention also proposes following attached technical scheme：
The interface of described two different acoustical materials is serrated.
The sound-absorbing component includes sound absorption wedge and acoustical cotton, and the acoustical cotton is filled in the sound absorption wedge and described worn
Between orifice plate.
The sound-absorbing component can be arranged to multilayer.
Compared to prior art, the advantage of the invention is that：The present invention passes through the interlaced arrangement sound to sound-absorbing material
Sound has bigger loss, so that acoustic(al)absorbent has more preferably sound-absorbing effect.
Brief description of the drawings
Fig. 1 is the schematic perspective view of acoustic(al)absorbent of the present invention.
Fig. 2 is the sectional view of acoustic(al)absorbent of the present invention.
Embodiment
Technical solution of the present invention is further non-limitingly described in detail below in conjunction with preferred embodiment and its accompanying drawing.
As shown in Figure 1 to Figure 2, corresponding to a kind of acoustic(al)absorbent of preferred embodiment of the present invention, including perforated plate 1, housing 5 with
And sound-absorbing component 2, housing 1 have inner chamber and opening, perforated plate 1 can close the opening, and sound-absorbing component 2 is arranged on housing 1
Interior intracavitary.Housing 5 and perforated plate 1 can be made up of metal sheet of sheet metal process, can also use wood materials.Perforated plate
1 surface offers many aperture 1a.
Sound-absorbing component 2 is formed by least two material interlaced arrangements with different acoustic properties, two kinds of different acoustics
The interface 6 of the material of matter can be arranged to zigzag, and in the present embodiment, sound-absorbing component 2 includes sound absorption wedge 3 and acoustical cotton 4.
The bottom surface of sound absorption wedge 3 is in contact with the bottom surface 5a of housing 5, and is covered with the bottom surface of housing 1, in sound absorption wedge 3 and perforated plate 1
Acoustical cotton 4 is filled between gap.
Sound, by two media intersection, can produce refraction in incidence, produce friction and acoustics is converted into heat energy,
Increase sound loss rate, therefore different medium intersection can have to sound effect is more preferably lost.The present invention is by housing 5
Two kinds of different sound-absorbing materials are set, and the interface 6 of two kinds of sound-absorbing materials is zigzag so that there is energy when sound is incoming
Bigger loss so that the sound-absorbing effect of acoustic(al)absorbent is more preferable.
The sound-absorbing component of the present invention is not limited to two kinds of sound-absorbing materials, can also be by sound-absorbing in order to reach more preferable effect
Component 2 is arranged to multilayer in a manner described.
The present invention to the interlaced arrangement sound of sound-absorbing material by having bigger loss, so that acoustic(al)absorbent has more
Good sound-absorbing effect.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Allow person skilled in the art to understand present disclosure and implement according to this, the protection of the present invention can not be limited with this
Scope.Any equivalent change or modification in accordance with the spirit of the invention, it should all be included within the scope of the present invention.
Claims (4)
1. a kind of acoustic(al)absorbent, including housing (5) and the perforated plate (1) that is connected with the housing (5), it is characterised in that：The suction
Sound body also includes sound-absorbing component (2), and the sound-absorbing component (2) is by least two material interlaced arrangements with different acoustic properties
Form.
2. according to acoustic(al)absorbent described in claim 1, it is characterised in that：The interface (6) of described two different acoustical materials is in saw
Dentation.
3. according to acoustic(al)absorbent described in claim 2, it is characterised in that：The sound-absorbing component (2) includes sound absorption wedge (3) and sound-absorbing
Cotton (4), the acoustical cotton (4) are filled between the sound absorption wedge (3) and the perforated plate (1).
4. according to any one of claims 1 to 3 acoustic(al)absorbent, it is characterised in that：The sound-absorbing component (2) can be arranged to more
Layer.
