It is applicable to the sound absorption design of hard wall, has synthesized the plane and has inhaled sound cotton structure and space acoustic absorber structure, when improving absorbing effect greatly, guarantees wall intensity and pleasing to the eye.
Description
Technical field
This utility model belongs to technical field of sound isolation, is specially one and efficiently absorbs sound body of wall.
Background technology
In traditional body of wall acoustical technology, it is usually and is paved with acoustical cotton at surface of wall, this simple in construction, but space availability ratio is low, sound-absorbing effect is not high, in order to improve space availability ratio, improve sound-absorbing effect, also have the design structure adopting suspended absorber, but adopt suspended absorber structure more complicated, metope rigidity is relatively low, it is easy to damaged, and installs extremely inconvenient.
Utility model content
The purpose of this utility model is for problem above, there is provided one efficiently to absorb sound body of wall, it is adaptable to the Sound absorption design of hard metope, combine structure and the suspended absorber structure of plane acoustical cotton, while being greatly improved sound-absorbing effect, it is ensured that metope intensity and attractive in appearance.
For realizing object above, the technical solution adopted in the utility model is: one efficiently absorbs sound body of wall, and it includes body of wall (6), and described body of wall (6) surface configuration has acoustical cotton (5)；Described acoustical cotton (5) surface is evenly arranged with sound-absorbing cone (4)；Described acoustical cotton (5) is fixed on body of wall (6) surface by the keel shoe (3) in groined type shape；Described acoustical cotton (5) is provided above abatvoix (2)；Described abatvoix (2) surface configuration has microperforated panel (1)；Described abatvoix is evenly arranged with aperture on (2)；Described aperture reverse side is provided with horn mouth body (21).
Further, described keel shoe (3) is clamping joist structure.
Further, described keel shoe (3) is fixed on body of wall (6) by expansion bolt (7).
Further, described acoustical cotton (5) surface is additionally provided with rustless steel steel wire.
Further, the circular cone drift angle of described sound-absorbing cone (4), horn mouth body (21) circular cone drift angle be all higher than 60 degree.
The beneficial effects of the utility model:
This utility model combines structure and the suspended absorber structure of plane acoustical cotton, while being greatly improved sound-absorbing effect, it is ensured that metope intensity and attractive in appearance.

Shown in figure, numerical reference is expressed as: 1, microperforated panel, and 2, abatvoix, 3, keel shoe, 4, sound-absorbing cone, 5, acoustical cotton, 6, body of wall, 7, expansion bolt, 21, horn mouth body.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model; below in conjunction with accompanying drawing, this utility model is described in detail; the description of this part is only exemplary and explanatory, and protection domain of the present utility model should not have any restriction effect.
As Figure 1-Figure 4, concrete structure of the present utility model is: one efficiently absorbs sound body of wall, and it includes body of wall 6, and described body of wall 6 surface configuration has acoustical cotton 5；Described acoustical cotton 5 surface is evenly arranged with sound-absorbing cone 4；Described acoustical cotton 5 is fixed on body of wall 6 surface by the keel shoe 3 in groined type shape；Described acoustical cotton 5 is provided above abatvoix 2；Described abatvoix 2 surface configuration has microperforated panel 1；Described abatvoix 2 is evenly arranged with aperture；Described aperture reverse side is provided with horn mouth body 21.
Preferably, described keel shoe 3 is clamping joist structure.
Preferably, described keel shoe 3 is fixed on body of wall 6 by expansion bolt 7.
Preferably, described acoustical cotton 5 surface is additionally provided with rustless steel steel wire.
Preferably, the circular cone drift angle of described sound-absorbing cone 4, horn mouth body 21 circular cone drift angle be all higher than 60 degree.
This utility model principle:
Sound is passed between microperforated panel 1 and abatvoix 2 through microperforated panel 1, produce first time concussion, it is consumed energy, sound again passes through abatvoix 2, enter the space between abatvoix 2 and acoustical cotton 5, in this space, sound again produces concussion between sound-absorbing cone 4 and horn mouth body 21, conical structure due to sound-absorbing cone 4 with horn mouth body 21, sound is made not only to produce vertical concussion, also produce side concussion, and, interpolation due to horn mouth body 21, sound cannot be returned away, in continuous concussion process, sound is constantly fully absorbed by acoustical cotton 5 and sound-absorbing cone 4, acoustical cotton structure and suspended absorber structure that its sound-absorbing effect is more traditional improve 30%-50%.
It should be noted that, in this article, term " includes ", " comprising " or its any other variant are intended to comprising of nonexcludability, so that include the process of a series of key element, method, article or equipment not only include those key elements, but also include other key elements being not expressly set out, or also include the key element intrinsic for this process, method, article or equipment.
Principle of the present utility model and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to help to understand method of the present utility model and core concept thereof.The above is only preferred implementation of the present utility model, should be understood that, finiteness due to literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, under the premise without departing from this utility model principle, it is also possible to make some improvement, retouching or change, it is also possible to above-mentioned technical characteristic is combined by rights；These improve retouching, change or combination, or the not improved design by utility model and technical scheme directly apply to other occasion, are regarded as protection domain of the present utility model.
