Description
Technical field
The utility model relates to interior decoration technologies, more specifically, it is related to a kind of soundproof plate.
Background technique
In recent years, the factor for influencing people's sleep quality is more and more, one of them critically important factor is exactly noise dirt
Dye, noise are a kind of sound for causing people's agitation to be even detrimental to health, and people can be caused by being chronically in the environment of noise
The injury such as body impaired hearing；In general, the noise on road is generally 80-90 decibels, and when vehicle whistle, noise can reach
To 110 decibels, to living in for close to the crowd of road, noise pollution is especially prominent；Therefore in order to improve sleep quality,
When fitting up to house, more and more people's selection is laid with soundproof plate on wall, to reduce noise pollution.
Existing soundproof plate is made of the plate for being equipped with acoustical cotton mostly, and acoustical cotton is a kind of manmade inorganic fibre, due to
It is crossings on different level between fiber and fiber, winds mutually, it may appear that many tiny gaps, when sound wave passes through acoustical cotton, meeting
It enters in these gaps, disperses sound wave, reduce the energy transmission of sound wave, to play the purpose of flat noise abatement.But
The structure of existing soundproof plate is simple, and noise can usually be reduced 20-30 decibels by traditional sound-proof material, and be suitble to people's sleep
Sound be to be not obvious only by the effect of acoustical cotton noise reduction, therefore how to improve soundproof plate lower than 30 decibels
Soundproof effect be one and need to solve the problems, such as.
Utility model content
In view of the deficienciess of the prior art, passing through sound insulation the purpose of this utility model is to provide a kind of soundproof plate
The baffle being staggered on slot can reduce the propagation energy of sound, play the role of flat noise abatement.
To achieve the above object, the utility model provides following technical solution: a kind of soundproof plate, including substrate, fixed
In on substrate the first abatvoix, be fixedly arranged on second abatvoix of first abatvoix far from substrate side and be fixedly arranged on the second suction
Acoustical cotton of the soundboard far from the first abatvoix side offers the sound insulation slot through its plate face on first abatvoix；It is described
The multiple baffles being staggered are installed in the two lateral walls of sound insulation slot along its length.
By using above-mentioned technical proposal, when sound passes through substrate, due to offering sound insulation slot on the first abatvoix, because

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Referring to Figures 1 and 2, it is a kind of soundproof plate disclosed by the utility model, including substrate 1, is fixedly arranged on 1 side of substrate
First abatvoix 2 is fixedly arranged on that second abatvoix 3 of first abatvoix 2 far from 1 side of substrate, to be fixedly arranged on the second abatvoix 3 separate
The acoustical cotton 4 of first abatvoix, 2 side and be fixedly arranged on acoustical cotton 4 outside diatom mud layer 5；Referring to figs. 2 and 3, first
The sound insulation slot 21 through its plate face is offered on abatvoix 2, sound insulation slot 21 is obliquely installed, the phase of sound insulation slot 21 along its length
To being installed with the multiple baffles 22 being staggered on two sidewalls.When sound passes through substrate 1, some sound is understood easily
Enter in sound insulation slot 21, for sound by the baffle 22 of setting of being interspersed, the propagation path of sound becomes tortuous at this time, with
The energy of sound can be made to cause damages after the multiple impacts of baffle 22, then sound reaches the second abatvoix 3 from sound insulation slot 21
On, then reach on acoustical cotton 4, the porous structure of acoustical cotton 4 can absorb the energy of sound again at this time, then remaining sound
It is absorbed again by porous diatom mud layer 5 again, so as to play the purpose of further flat noise abatement.
Referring to Fig. 3 and Fig. 4, offer the link slot 31 for being connected to sound insulation slot 21 on the second abatvoix 3, link slot 31 with every
Sound slot 21 forms " V " shape structure；Connecting tube 32, the end of one end protrusion link slot 31 of connecting tube 32 are installed on link slot 31
Setting, sound insulation slot 21 offer fixing groove 211 close to one end of the second abatvoix 3, and connecting tube 32 protrudes one end of link slot 31
It is embedded in fixing groove 211, so that connecting tube 32 be made to be fixedly connected on fixing groove 211；Connecting tube 32 is connected to sound insulation slot 21, even
Adapter tube 32 and sound insulation slot 21 form " V " shape structure.Sound can lose an energy after sound insulation slot 21, at this time due to link slot 31
On connecting tube 32 be connected to sound insulation slot 21, from sound insulation slot 21 come out sound can enter in connecting tube 32, due to sound insulation
Slot 21 and connecting tube 32 form " V " shape structure, when sound enters connecting tube 32 from sound insulation slot 21, and have the energy of part
Loss improves the purpose of noise reduction into one.
Referring to Fig. 3 and Fig. 4, the side wall of substrate 1 is installed with fin 11, the connection of fin 11 and substrate 1 along its length
Place offers clamping groove 111；Substrate 1 is consolidated on groove 12 relative to opening up fluted 12 on another side wall for being equipped with fin 11
Equipped with the clamping block 13 that can be connected in clamping groove 111, sound absorbing layer 112 is installed on the outer wall of fin 11.It is laid with to wall
When soundproof plate, need to splice multiple soundproof plates, but the side wall of soundproof plate can have a mismachining tolerance, adjacent two every
Soundboard after splicing, its splicing position can there are gaps, when sound passes through wall, have partial noise from its gap
It is propagated, influences the effect of noise reduction；Therefore when being installed to soundproof plate, the fin 11 being fixedly arranged on substrate 1 is clamped
It in the groove 12 of another substrate 1, is connected to the clamping groove 111 on groove 12 in the clamping groove 111 of fin 11, can incite somebody to action
Two adjacent soundproof plates are fixed, and improve the compactness of the connection of adjacent abatvoix, reduce the gap of junction, and
Sound absorbing layer 112 is installed on the outer wall of fin 11, when sound passes through the junction of soundproof plate, the sound of part can be by fin 11
On sound absorbing layer 112 absorb, improve soundproof effect.
The implementation principle of the present embodiment are as follows: when sound passes through substrate 1, understand some sound and enter sound insulation slot 21
In, sound is by the baffle 22 of setting of being interspersed at this time, the energy of sound can be made to make after with the multiple impacts of baffle 22
At loss, then sound is reached on the second abatvoix 3 by being connected to the connecting tube 32 of sound insulation slot 21, due to sound insulation slot 21 and even
Adapter tube 32 forms " V " shape structure, when sound enters connecting tube 32 from sound insulation slot 21, and has the energy loss of part；So
Sound reaches on acoustical cotton 4 from connecting tube 32 again afterwards, and the porous structure of acoustical cotton 4 can absorb the energy of sound again at this time,
Last remaining sound passes through porous diatom mud layer 5 again to be absorbed again, subtract so as to play further flat
The purpose made an uproar.
When installing to soundproof plate, the fin 11 being fixedly arranged on substrate 1 is connected to the groove 12 of another substrate 1
In, it is connected to the clamping groove 111 on groove 12 in the clamping groove 111 of fin 11, two adjacent soundproof plates can be carried out
It is fixed, the compactness of the connection of adjacent abatvoix is improved, the gap of junction is reduced, improves soundproof effect.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
