Abstract
The utility model discloses a kind of acoustic(al)absorbent, the perforated plate (1) being connected including housing (5) and with the housing (5), it further includes sound-absorbing component (2), and the material interlaced arrangement that the sound-absorbing component (2) has different acoustic properties by least two forms.The interface (6) of described two difference 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 utility model has more preferably sound-absorbing effect.
Description
Technical field
The utility model is related to a kind of acoustic(al)absorbents.
Background technology
The general surface of traditional acoustic(al)absorbent uses perforated plate, and single acoustical cotton is filled in inside, and sound-absorbing is inefficient.
Utility model content
The purpose of this utility model is that for drawbacks described above of the prior art, provide a kind of sound-absorbing more efficient suction
Sound body.
To realize above-mentioned purpose of utility model, the utility model employs following technical solution：One kind, including housing and with
The perforated plate that the housing is connected, the acoustic(al)absorbent further include sound-absorbing component, and the sound-absorbing component has difference by least two
The material interlaced arrangement of acoustic properties forms.
In addition, the utility model also proposes following attached technical scheme：
The interface of described two difference 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 wears
Between orifice plate.
The sound-absorbing component can be arranged to multilayer.
Compared with the prior art, the utility model has the advantage of：The utility model passes through the staggeredly cloth to sound-absorbing material
It puts so that sound has the loss of bigger, so as to which acoustic(al)absorbent be made to have more preferably sound-absorbing effect.
Description of the drawings
Fig. 1 is the stereoscopic schematic diagram of the utility model acoustic(al)absorbent.
Fig. 2 is the sectional view of the utility model acoustic(al)absorbent.
Specific embodiment
Technical solutions of the utility model are made below in conjunction with preferred embodiment and its attached drawing further unrestricted detailed
Explanation.
As shown in Figure 1 to Figure 2, corresponding to a kind of acoustic(al)absorbent of preferred embodiment of the utility model, including perforated plate 1, shell
Body 5 and sound-absorbing component 2, housing 1 have inner cavity and opening, and perforated plate 1 can close the opening, and sound-absorbing component 2 is arranged on shell
The interior intracavitary of body 1.Housing 5 and perforated plate 1 can be made up of metal sheet of sheet metal process, can also use wood materials.
1 surface of perforated plate offers many aperture 1a.
The material interlaced arrangement that sound-absorbing component 2 has different acoustic properties by least two forms, 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 generate refraction in incidence, generate friction and acoustics is converted to thermal energy,
Increase sound loss rate, therefore different medium intersection there can be sound effect is more preferably lost.The utility model passes through in shell
The two different sound-absorbing materials of setting in body 5, and the interface 6 of two kinds of sound-absorbing materials is zigzag so that when sound is passed to
Energy has the loss of bigger so that the sound-absorbing effect of acoustic(al)absorbent is more preferable.
The sound-absorbing component of the utility model is not limited to two kinds of sound-absorbing materials, in order to reach better effect, can also incite somebody to action
Sound-absorbing component 2 is arranged to multilayer in a manner described.
The utility model has the loss of bigger by the interlaced arrangement sound to sound-absorbing material, so as to have acoustic(al)absorbent
There is more preferably sound-absorbing effect.
It should be pointed out that above-mentioned preferred embodiment is only to illustrate the technical concepts and features of the utility model, purpose
It is the content for allowing person skilled in the art that can understand the utility model and implements according to this, can not this reality be limited with this
With novel protection domain.All equivalent change or modifications substantially made according to the spirit of the present invention, should all cover in this reality
Within novel protection domain.
Claims (4)
1. a kind of acoustic(al)absorbent, the perforated plate (1) being connected including housing (5) and with the housing (5), it is characterised in that：The suction
