Abstract
The utility model discloses a kind of sound panel, which includes bottom plate, the intermediate plate being arranged on bottom plate and the perforated plate being arranged on intermediate plate, and several through-holes are offered on the perforated plate；That side that intermediate plate corresponds to perforated plate is opened up there are one cavity, and the bottom plate of the cavity is provided with side acoustical cotton, and the depth of cavity is more than the thickness of acoustical cotton；That side that intermediate plate corresponds to bottom plate is provided with several convex blocks, and each high spot is corresponded on bottom plate and offers blind hole respectively, and a spring is respectively arranged in each blind hole, and each convex block is inserted into respectively in that corresponding blind hole.Sound panel provided by the utility model realizes sound-absorbing three times, so as to improve final soundproof effect.
Description
Technical field
The utility model is related to building materials technology field, more particularly to a kind of sound panel.
Background technology
In the prior art, sound panel is mainly by setting acoustic material (such as：Felt, foamed plastics, super glass wool etc.)
The effect of sound insulation is played, however, in order to which the thickness for improving soundproof effect and increasing acoustic material simply is clearly uneconomical
, and sound insulation plate thickness is caused to increase, the space of bigger is occupied, sound panel weight is also caused to increase, is not easy to carry and pacify
Dress.
As it can be seen that the prior art could be improved and improve.
Utility model content
Part in view of above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of sound panels, it is intended to solve
Certainly in the prior art sound panel by increasing acoustic material thickness come the technical issues of improving soundproof effect.
In order to achieve the above object, the utility model takes following technical scheme：
A kind of sound panel, including bottom plate, the intermediate plate being arranged on bottom plate and the perforated plate being arranged on intermediate plate,
Several through-holes are offered on the perforated plate；That side that intermediate plate corresponds to perforated plate is opened up there are one cavity, the bottom plate of the cavity
Side acoustical cotton is provided with, the depth of cavity is more than the thickness of acoustical cotton；Intermediate plate correspond to bottom plate that side be provided with it is several
Convex block corresponds on bottom plate and offers blind hole at each convex block respectively, a spring, each convex block are respectively arranged in each blind hole
It is inserted into respectively in that corresponding blind hole.
In the sound panel, that side that the acoustical cotton corresponds to perforated plate is provided with several protrusions, on acoustical cotton
Each protrusion is arranged in matrix.
In the sound panel, the acoustical cotton is melamine acoustical cotton.
In the sound panel, the perforated plate is aluminium sheet.
In the sound panel, the intermediate plate and bottom plate are plank.
Advantageous effect：
The utility model provides a kind of sound panel, compared with prior art, by setting sound panel, acoustical cotton, spring etc.
Component realizes sound-absorbing three times, so as to improve final soundproof effect, avoids as prior art by improving sound-absorbing
The thickness of material improves soundproof effect, therefore, while ensureing that sound panel has stronger soundproof effect, ensure that sound insulation
The thickness and weight of plate do not increase significantly.
Description of the drawings
Fig. 1 is the front view of sound panel provided by the utility model.
Fig. 2 is A-A sectional views in Fig. 1.
Fig. 3 is the partial enlarged view in S regions in Fig. 2.
Specific embodiment
The utility model provides a kind of sound panel, for make the purpose of this utility model, technical solution and effect it is clearer,
Clearly, the utility model is further described in the embodiment that develops simultaneously referring to the drawings.It should be appreciated that tool described herein
Body embodiment only to explain the utility model, is not used to limit the utility model.
It please refers to Fig.1 to Fig.3, the utility model provides a kind of sound panel.
The sound panel includes bottom plate 1, the intermediate plate 2 being arranged on bottom plate and the perforation being arranged on intermediate plate
Plate 3 offers several through-holes 31 on the perforated plate 3；That side that intermediate plate 2 corresponds to perforated plate 3 is opened up there are one cavity 201,
The bottom plate of the cavity is provided with side acoustical cotton 4, and the depth of cavity 201 is more than the thickness of acoustical cotton 4；Intermediate plate 2 corresponds to bottom plate
That side be provided with several convex blocks 21, corresponded on bottom plate 1 at each convex block and offer blind hole respectively（With the position phase of convex block 21
Together）, a spring 5 is respectively arranged in each blind hole, and each convex block is inserted into respectively in that corresponding blind hole.
Sound insulation principle described briefly below：Since the depth of cavity is more than the thickness of acoustical cotton, acoustical cotton and perforated plate it
Between formed one layer of air layer, that is, each through-hole is to there is corresponding cavity on perforated plate；Enter after incident acoustic wave passes through perforated plate
Evoke the air-column vibration in perforated plate through-hole in air layer, when the vibration frequency of incident acoustic wave and the vibration frequency one of air column
Cause is to evoke resonance, so as to which acoustic energy is converted thermal energy and kinetic energy, achievees the purpose that sound-absorbing；When sound wave further passs through acoustical cotton
When again serve to sound-absorbing, acoustic energy further weakens.Due to being provided with spring between intermediate plate and bottom plate, when sound wave passes through intermediate plate
During with bottom plate, play the role of third time sound-absorbing.It can be seen that the utility model is improved by the structure to sound panel, pass through
Sound-absorbing improves final soundproof effect three times, is improved as existing by increasing the thickness of sound-absorbing material even if avoiding
Soundproof effect.
Further, the acoustical cotton 4 corresponds to that side of perforated plate and is provided with several raised 41, each on acoustical cotton
Protrusion is arranged in matrix, further improves the sound-absorbing effect of acoustical cotton.
Specifically, the acoustical cotton 4 is melamine acoustical cotton.Melamine abatvoix described herein is referred to by three
Poly cyanamid Foam machining forms, and has the comprehensive performances such as unique sound-absorbing, heat-insulated, fire-retardant, high temperature resistant, light.
Preferably, the perforated plate 3 is aluminium sheet so that perforated plate is more frivolous.
Preferably, the intermediate plate 2 and bottom plate 1 are plank.
It is understood that for those of ordinary skills, can with technical solution according to the present utility model and
The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement should all belong to appended by the utility model
Scope of the claims.
