Description

Sound screening arrangement

Technical field

The utility model is related to environmental technology field, more particularly to a kind of sound for reducing noise pollution to shield dress Put.

Background technology

With growing continuously and fast for China's economic, noise pollution has also increasingly had a strong impact on the physically and mentally healthy of people and life How quality living, control noise pollution to turn into the problem urgently paid attention to and solve in modern social development.In order to reduce noise Influence, it will usually set up sound screening arrangement to abate the noise in noise source periphery.But existing sound screening arrangement noise reduction effect Fruit is not obvious, and manufacture method is complicated.

Utility model content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of erasure effect preferably and manufacture The simple sound screening arrangement of method.

The purpose of this utility model is realized using following technical scheme：

A kind of sound screening arrangement, including a housing and the abatvoix located at the outer inframe, the housing are provided with Some acoustics mouthful, each acoustics mouthful is inwardly recessed through the housing, and is formed at simultaneously on the housing and abatvoix.

Preferably, each acoustics mouthful includes one first acoustics mouthful and one second acoustics connected with first acoustics mouth Mouthful, first acoustics mouthful passes through the housing, and the second acoustics mouth is formed on the abatvoix, first acoustics Mouth, the second acoustics mouthful are seamlessly transitted.

Preferably, the acoustics mouthful is the long groove shape of triangular pyramid, and the section of the acoustics mouthful is del, its bore Tapered into along the depth direction being inwardly recessed.

Preferably, each acoustics mouthful includes one first acoustics mouthful and one second acoustics connected with first acoustics mouth Mouthful, first acoustics mouthful passes through the housing, and the second acoustics mouth is formed on the abatvoix, first acoustics mouthful Section be inverted trapezoidal, the section of second acoustics mouthful is del, and the lower relative aperture of first acoustics mouthful is equal to described The upper bore of the second acoustics mouthful.

Preferably, the section of the acoustics mouthful is the long groove shape of inverted trapezoidal or section is the spherical of cambered surface.

Preferably, the housing, abatvoix are cuboid-type.

Preferably, the acoustics opening's edge the housing length direction longitudinal direction it is neat or be staggered.

Preferably, the housing is the mixed mud of sand and cement composition, and the abatvoix is by perlite blended cement Into.

Preferably, the periphery of the abatvoix is also formed with some rough outer laces, and the inside of housing then shape Into the interior lace being engaged with the outer lace.

Preferably, the housing is packaged in the periphery of the abatvoix.

Compared to existing technology, in sound screening arrangement of the present utility model, acoustics mouth is inwardly recessed through described outer Frame, and be formed at simultaneously on the housing and abatvoix, therefore acoustic construction can be formed on the housing and abatvoix simultaneously, On the one hand the noise of outside can be absorbed by the abatvoix, and still further aspect also can be by the sound on the housing and abatvoix The acoustic construction that mouth is formed repeatedly reflects counteracting, so as to can reduce noise effect, reach preferable erasure effect.

Specific embodiment

Fig. 1 and Fig. 2 is referred to, is the sound screening arrangement in the utility model first embodiment, the sound shielding dress The abatvoix 20 including a housing 10 and in the housing 10 is put, the housing 10 is packaged in the outer of the abatvoix 20 Enclose.

The housing 10 is the mixed mud of sand and cement composition, and it is cuboid-type, and certainly, the housing 10 can also It is other shapes, such as square.The front surface of the housing 10 is provided with some acoustics mouthful 11, and each acoustics mouthful 11 concaves Enter through the housing 10, and be formed at simultaneously on the housing 10 and abatvoix 20, i.e., each acoustics mouthful 11 includes one first Acoustics mouthful 111 and one second acoustics mouthful 112 connected with first acoustics mouthful 111, first acoustics mouthful 111 passes through described Housing 10, second acoustics mouthful 112 is formed on the abatvoix 20, first acoustics mouthful the 111, second acoustics mouthful 112 Seamlessly transit.In the present embodiment, the acoustics mouthful 11 is the long groove shape of triangular pyramid, its along the housing 10 length side To longitudinal proper alignment, the section of the acoustics mouthful 11 is del, its bore along the depth direction being inwardly recessed gradually Diminish, i.e., the section of described first acoustics mouthful 111 is inverted trapezoidal, the section of second acoustics mouthful 112 is del, described The lower relative aperture of the first acoustics mouthful 111 is equal to the upper bore of second acoustics mouthful 112.Certainly, the acoustics mouthful 11 can also be Other shapes, such as section are the long groove shape of inverted trapezoidal, section for cambered surface is spherical, in addition, the acoustics mouthful 11 can also be Arranged in other orders according to actual needs, be such as staggered.

The abatvoix 20 is made up of sound-absorbing material, and in the present embodiment, it is formed by perlite blended cement.The suction Soundboard 20 is cuboid-type, and certainly, the abatvoix 20 can also be other shapes, such as square.The abatvoix 20 leads to The acoustics mouthful 11 is crossed to be in communication with the outside.

In tut screening arrangement, the acoustics mouthful 11 is inwardly recessed through the housing 10, and is formed at institute simultaneously State on housing 10 and abatvoix 20, therefore acoustic construction can be formed on the housing 10 and abatvoix 20 simultaneously, outside is made an uproar On the one hand sound can be absorbed by the abatvoix 20, and still further aspect also can be by the acoustics on the housing 10 and abatvoix 20 The acoustic constructions that mouth 11 is formed repeatedly reflect counteracting, so as to can reduce noise effect, reach preferable erasure effect.

Fig. 3 is referred to, is the sound screening arrangement in the utility model second embodiment, the sound shielding in the present embodiment Device is essentially identical with sound screening arrangement in first embodiment, and its difference is：Sound shielding in the present embodiment The periphery of the abatvoix 20a of device is also formed with some rough outer lace 23a, and the inside of housing 10a then formed with The interior lace 13a that the outer lace 23a is engaged.In this way, the interior lace of the outer lace 23a and housing 10a of the abatvoix 20a 13a combines closely, and is conducive to being combined more firm with housing 10a by the abatvoix 20a.

It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of the utility model claim Within the scope of.
