Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type embodiment is described in further detail.
With reference to Fig. 1-Fig. 3, a kind of cycle born of the same parents structure composite sound panel of the present utility model, including the panel 1 of upper end, lower end
Backboard 5, n (n >=1) individual connected unit cell between panel 1 and backboard 5；The unit cell include cycle born of the same parents' sandwich layer 7, on
Side plate 21, lower side panel 22, microperforated panel 3, porous material 4, inert gas 8；
The cycle born of the same parents sandwich layer 7 is border structure, and between panel 1 and backboard 5, panel 1 and backboard 5 have been connected
Come；The epipleural 21, lower side panel 22, microperforated panel 3, porous material 4 are installed on cycle born of the same parents' sandwich layer 7, the micropunch
Plate 3 is arranged on the bosom of cycle born of the same parents' sandwich layer 7；The epipleural 21, lower side panel 22 are installed in the outer of cycle born of the same parents' sandwich layer 7
Enclose, epipleural 21 is between panel 1 and microperforated panel 3, and lower side panel 22 is between porous material 4 and microperforated panel 3；It is described
Panel 1, backboard 5, epipleural 21, lower side panel 22, cycle born of the same parents' sandwich layer 7 form the cavity body structure of unit cell together；The epipleural 21,
Lower side panel 22 forms the side plate of unit cell together；The porous material 4 is arranged on the bottom of cycle born of the same parents' sandwich layer 7, and is connect with backboard 5
Touch；Unit cell is divided into upper plenum 211 and lower cavity 221 by the microperforated panel 3, while the multiple through holes set on microperforated panel 3
31 are connected cavity 211 with lower cavity 221；Connected unit cell shares identical side plate, and the side plate of connected unit cell is provided with
Through hole 6, the cavity between connected unit cell is connected；The backboard 5 is provided with injecting hole 9, for filling inertia into unit cell
Gas；Inert gas 8 is filled with the cavity of the unit cell, to absorb sound wave.
Further, the through hole 6, with sound energy consumption, reduces acoustic energy transmission perpendicular to unit cell side plate planar.
Further, between the epipleural 21, lower side panel 22, microperforated panel 3, porous material 4 and cycle born of the same parents' sandwich layer 7
It is installed as being interference fitted.So so that epipleural 21, lower side panel 22, microperforated panel 3, the porous material installed on cycle born of the same parents' sandwich layer 7
Material 4 will not occur relative motion and produce vibration.
Further, to increase sound transmission loss, the material of the panel 1 and backboard 5 is rubber or fiberglass；The upside
The material of plate 21 and lower side panel 22 is rubber or elastoplast；The material of the microperforated panel 3 is PVC plastic；It is described porous
Material 4 is mineral wool or porous fibrous material, and the inert gas 8 is argon gas or helium；The material of the cycle born of the same parents sandwich layer 7 is
Polyethylene or the big metal of density, such as copper, iron.
Further, the panel 1 and backboard 5 are pasted with the use of cycle born of the same parents' sandwich layer 7 or screw is affixed.
Further, the cycle born of the same parents sandwich layer 7 is the polygon edge mount structures such as quadrangle, pentagon.
During work, inert gas 8 first is poured from injecting hole 9, the cavity inside of unit cell is full of inert gas 8；Work as noise
After spreading into cycle born of the same parents' structure composite sound panel in the form of a sound wave, sound wave is reflected by panel 1 so that sound wave enters
Decay is received before entering unit cell；After sound wave enters unit cell, by the absorption of inert gas 8, so as to decay again；After decay
Sound wave after the absorption of microperforated panel 3 acoustic energy decline, microperforated panel 3 primarily serve absorb low-frequency sound wave effect；Sound wave
Again after the absorption of porous material 4, volume is largely absorbed, and porous material primarily serves the effect for absorbing high frequency sound wave；Worn through micro-
Sound wave after the absorption of orifice plate 3 is consumed totally after being driven again by internal porosity 6, so that the sound wave through backboard 5 is micro-
Its is micro-, reaches the effect of sound insulation.
Although the utility model is disclosed above with preferred embodiment, so it is not limited to the utility model.This reality
With new those of ordinary skill in the art, do not departing from spirit and scope of the present utility model, it is each when that can make
The change and retouching of kind.Therefore, the scope of protection of the utility model is worked as and is defined depending on those as defined in claim.
