Description
Technical field
The utility model is related to railway, road communications vocation field of Environment Protection, and in particular to a kind of wedging type abatvoix.
Background technology
The surface of current abatvoix is in plane, using filling sucting sound material system in the spraying of metallic plate through hole more than abatvoix
Form, the surface of abatvoix there are many apertures, and sound enters after aperture, penetrates into inside sound-absorbing material and propagate forward, inhaled
After sound material absorbs, defening effect is reached.Existing abatvoix feature is poor, and soundproof effect is poor, although environmental protection, but not beautiful
See.Style is more single, it is impossible to meet high-quality requirement of the people to environmental protection.Therefore, prior art need to be improved.
Utility model content
To overcome the defect present in prior art, now there is provided a kind of wedging type abatvoix, to solve soundproof effect
Poor and inaesthetic problem.
The utility model provides a kind of wedging type abatvoix, including sound absorption panel, sound absorption backboard and sound absorber, the suction
Sound panel is fixedly connected to form the frame chamber of a placement sound absorber with the sound absorption backboard, and the sound absorption panel passes through with sound absorption backboard
Machine is one time punching molded, and the sound absorption panel is provided with tip and base portion, and the tip is set with the base portion equidistant intervals
Put.
In terms of existing technologies, the utility model is fixed into wedge by welding, without the fixed form being spirally connected etc.
Formula abatvoix, adds absorption area, makes it have the abatvoix of high acoustic absorption amount and long frequency bandwidth, incident acoustic energy is obtained height
The absorption of effect, is effectively saved material on the basis of stability structure is ensured, reduces production cost.
Further, the tip height is 18mm, and tip width is 33mm, the Sizes and easily absorbs acoustic energy.
Further, it is provided between the tip and the base portion after air layer, acoustic wave touch to the tip from air
Layer, which is transitioned into the base portion and arrives sound absorber again, realizes acoustic impedance match.It is thus achieved that impedance matching well, makes incident acoustic energy
Efficiently absorbed.
Brief description of the drawings
Fig. 1 is the assembling schematic diagram of the utility model wedging type abatvoix；
Fig. 2 is diagrammatic cross-section after the assembled formation of the utility model wedging type abatvoix；
Fig. 3 is the floor map after the assembled formation of the utility model wedging type abatvoix.
Reference in correspondence Figure of description is with reference to as follows：
Absorb sound panel 1, sound absorption backboard 2, sound absorber 3, tip 11, base portion 12.
Embodiment
In order that technological means, creation feature, reached purpose and effect that utility model is realized are easy to understand, below
With reference to accompanying drawing, the utility model is expanded on further.
The utility model provides a kind of wedging type abatvoix, as shown in Figures 1 and 2, including be made up of zinc-plating material
Absorb sound panel 1, sound absorption backboard 2 and sound absorber 3, and sound absorption panel 1 is connected with sound absorption backboard 2 and forms a frame chamber for placing sound absorber 3,
Sound absorber 3 is connected with sound absorption panel 1 by professional rivet clasp, and sound absorber 3 can be made up of porous material, be easy to the suction to noise
Receive, sound absorption panel 1 and sound absorption backboard 2 are one time punching molded by machine, and sound absorption panel 1 is provided with tip 11 and base portion 12, point
The height of portion 11 is 18mm, and the width of tip 11 is 33mm, and tip 11 is equidistantly spaced with base portion 12, and between adjacent tip
Interval more than tip width.
In addition, being transitioned into base from air layer after being provided with air layer, acoustic wave touch to tip 11 between tip 11 and base portion 12
Portion 12 arrives sound absorber 3 and realizes acoustic impedance match again.It is thus achieved that impedance matching well, makes incident acoustic energy efficiently be inhaled
Receive.
Specifically, in conjunction with shown in Fig. 3, when sound wave touches sound absorption panel 1, from the tip 11 of wedge to base portion
12, acoustic impedance is that the impedance of sound absorber 3 is progressively transitioned into from the characteristic impedance of air, it is thus achieved that impedance well
Match somebody with somebody, incident acoustic energy is efficiently absorbed.
Wedging type abatvoix of the present utility model, by the way that sound absorption panel 1 is arranged into tip 11 and base portion 12, adds suction
Sound effective value, increases its absorption area, makes it have the abatvoix of high acoustic absorption amount and long frequency bandwidth.Improve after abatvoix installation
Stability, it is to avoid acoustic board occurs loosening or come off, and eliminates the potential safety hazard on road surface, prevents from causing traffic accident, lifting
Its security and service life.Material is effectively saved on the basis of stability structure is ensured, production cost is reduced.
The specific embodiment of utility model is described above.It is to be appreciated that utility model is not limited to
Above-mentioned particular implementation, wherein the equipment and structure be not described in detail to the greatest extent are construed as being given with the common mode in this area
To implement；Those skilled in the art, which can make various deformations or amendments within the scope of the claims and make, some simply to push away
Drill, deform or replace, this has no effect on the substantive content of utility model.
