Description

A kind of sound panel
Technical field
It the utility model is related to building materials field, and in particular to a kind of sound panel.
Background technology
Substantial amounts of dry source of sound, such as equipment operation, air compressor house, laboratory field are often produced during the manufacturing Institute, worker at the production line's body is caused to damage, therefore need to use sound panel to build in the region of employee's aggregation there is soundproof effect Sound insulation house.
Sound panel is made from alloy sheets, aluminium sheet encapsulation sound-absorbing material mostly at present, and sound-absorbing, soundproof effect are limited, make Valency is higher, and aluminium sheet is easily corroded and influences the life-span.Stainless steel has unique intensity, higher wearability, superior Antiseptic property and being not easy the excellent characteristic such as get rusty, be also commonly used for sound panel, but simple stainless steel materials sound insulation is made Effect is unsatisfactory.
Utility model content
In view of the shortcomings of the prior art, the utility model proposes a kind of simple in construction, sound-absorbing and soundproof effect it is good every Soundboard.
To realize above-mentioned technical proposal, the utility model provides a kind of sound panel, including:Outer sound panel, framework, sound-absorbing Cotton and inner baffle plate, symmetrically it is fixed on framework before and after the outer sound panel and inner baffle plate, acoustical cotton is clamped in outer sound panel Between inner baffle plate, the acoustical cotton is designed to the waveform at concave and convex surface interval close to the surface of inner baffle plate, described The circular hole of multiple matrix distributions that are square is offered in inner baffle plate, the acoustical cotton is designed as putting down close to the surface of outer sound panel Sliding surface, outer sound panel are solid wood board, plasterboard or metallic plate, and outer sound insulation plate surface is smooth, and outer sound panel and acoustical cotton are smooth Face is brought into close contact, and inner baffle plate is bonded with acoustical cotton wavy surfaces.
In the above-mentioned technical solutions, framework is used to be bonded fixed outer sound panel, acoustical cotton and inner baffle plate, and beneficial to this Splicing installation between sound panel.Because concave and convex surface be present in acoustical cotton surface, therefore when acoustical cotton and inner baffle plate fitting, Many cavitys are formed between acoustical cotton and inner baffle plate, when in noise transmission to cavity, entering by the resonance in cavity to noise Row buffering, so as to be segmented elimination partial noise, effectively weaken the propagation of noise, make soundproof effect more preferable.Simultaneously because acoustical cotton Combined closely between outer sound panel, and outer sound panel uses solid wood board, plasterboard or metallic plate, and noise is by early stage After decrease, noise can be completely cut off completely by outer sound panel, so as to reach the effect of sound insulation.
Preferably, the distance between described acoustical cotton surface upper recess surface bottom and convex surface top is 3-5mm, is sent out by experiment Existing, when the cavity depth formed between acoustical cotton and inner baffle plate is 3-5mm, the resonance effect between each cavity is best, It is maximum to the decrease amplitude of noise.
Preferably, the radius of circular hole is 0.2-0.6mm in the inner baffle plate, it is adjacent between centre distance be 0.4- 1.2mm, find that centre distance is 0.4- between the radius of circular hole in inner baffle plate is 0.2-0.6mm, is adjacent by experiment 1.2mm, and when being 3-5mm the distance between at the top of acoustical cotton surface upper recess surface bottom and convex surface, to the decrease amplitude of noise most Greatly.
Preferably, the framework uses stainless steel plate material or rock wool color plate material.
A kind of beneficial effect of sound panel provided by the utility model is:This septum arrangements is simple, ingenious in design, adds Work is easy, by designing the concave and convex surface on acoustical cotton surface, when acoustical cotton and inner baffle plate are bonded, and acoustical cotton and internal sound insulation Many cavitys are formed between plate, when in noise transmission to cavity, entering row buffering to noise by the resonance in cavity, so as to be segmented Partial noise is eliminated, effectively weakens the propagation of noise, and noise can be completely cut off completely by outer sound panel.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clear, complete description, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.The every other embodiment that ordinary people in the field is obtained under the premise of creative work is not made, is belonged to The scope of protection of the utility model.
Embodiment:A kind of sound panel.
It is shown referring to Figures 1 and 2, a kind of sound panel, including:Outer sound panel 10, framework 20, acoustical cotton 30 and inner baffle plate 40, symmetrically it is fixed on framework 20 before and after the outer sound panel 10 and inner baffle plate 40, acoustical cotton 30 is clamped in outer sound panel 10 Between inner baffle plate 40, the acoustical cotton 30 is designed to the wave at concave and convex surface interval close to the surface of inner baffle plate 40 Shape, the circular hole of multiple matrix distributions that are square is offered in the inner baffle plate 40, the acoustical cotton 30 is close to outer sound panel 10 Surface be designed as even surface, outer sound panel 10 is solid wood board, plasterboard or metallic plate, and the outer surface of sound panel 10 is smooth, outside Sound panel 10 is brought into close contact with the shiny surface of acoustical cotton 30, and inner baffle plate 40 is bonded with the wavy surfaces of acoustical cotton 30.
Operation principle of the present utility model is:Framework 20 is used to be bonded fixed outer sound panel 10, acoustical cotton 30 and internal sound insulation Plate 40, and beneficial to the splicing installation between this sound panel.Because concave and convex surface, therefore acoustical cotton be present in the surface of acoustical cotton 30 30 and inner baffle plate 40 when being bonded, many cavitys are formed between acoustical cotton 30 and inner baffle plate 40, when in noise transmission to cavity, Row buffering is entered to noise by the resonance in cavity, so as to be segmented elimination partial noise, effectively weakens the propagation of noise, makes sound insulation Effect is more preferable.Simultaneously because combined closely between acoustical cotton 30 and outer sound panel 10, and outer sound panel 10 is using solid wood board, stone Cream plate or metallic plate, noise can be completely cut off noise completely by outer sound panel 10, so as to reach after the decrease of early stage The effect of sound insulation.
In the present embodiment, the distance between the described surface upper recess surface bottom of acoustical cotton 30 and convex surface top is 4mm, by reality Issue after examination and approval now, when the cavity depth formed between acoustical cotton 30 and inner baffle plate 40 is 4mm, the resonance effect between each cavity Preferably, it is maximum to the decrease amplitude of noise.
In the present embodiment, the radius of circular hole is 0.5mm in the inner baffle plate 40, it is adjacent between centre distance be 1mm, warp Cross experiment to find, centre distance is 1mm between the radius of circular hole in inner baffle plate 40 is 0.5mm, is adjacent, and acoustical cotton 30 It is maximum to the decrease amplitude of noise when the distance between surface upper recess surface bottom and convex surface top are 4mm.
In the present embodiment, the framework 20 uses rock wool color plate material.
Described above is preferred embodiment of the present utility model, but the utility model should not be limited to the embodiment and Accompanying drawing disclosure of that, so every do not depart from the lower equivalent or modification completed of spirit disclosed in the utility model, all fall Enter the scope of the utility model protection.
