all offer the through-hole that supplies support column 12 to pass on first rock wool board 3, second rock wool board 4 and the wave crest sound absorption sponge 6.
The wave crest sound absorption sponge belongs to a common expression form of sound insulation material such as sound insulation cotton, and is a sound insulation material which is designed in a wave mode according to an acoustic principle. The design can reduce the sound source to the most reasonable degree through the refraction principle, the effect of attenuating sound waves is played mainly by absorbing the energy of the incident sound waves, and the wave crest sound absorption sponge has stronger capacity of absorbing high-frequency sound.
After adopting above-mentioned technical scheme, through strengthening subassembly 2 by first strengthening subassembly 1 and second and forming comparatively firm frame rack construction, and set gradually first rock wool board 3 that has certain clearance each other in the cavity 5 of frame, the sound sponge 6 and second rock wool board 4 are inhaled to the crest, first rock wool board 3 can effectual reduction echo, the crest is inhaled sound sponge 6 and can effectual absorption high frequency noise, and second rock wool board 4 can effectual absorption low frequency noise, and the crest is inhaled sound sponge 6 and first rock wool board 3, the air in the 4 clearances of second rock wool board also can be at the transmission of noise reduction sound energy to a certain extent, thereby the noise that makes to pass this strenghthened type and inhale the sound rock wool board weakens by a wide margin. This strenghthened type is inhaled sound rock wool board has sound construction, advantage that the sound absorbing capacity is strong.
Specifically, as shown in fig. 2, the exterior panel 11 is a flat straight plate, and the plurality of support pillars 12 are uniformly distributed on the exterior panel 11, in this embodiment, the number of the support pillars 12 is preferably five, four of the support pillars 12 are symmetrically disposed near four corners of the exterior panel 11, and the other support pillar is located at the center of the exterior panel 11.
Further, in order to improve the overall strength of the first reinforcement member 1, the exterior panel 11 is integrally formed with the support pillar 12.
In order to further improve the sound absorption effect, the second reinforcing component 2 is a porous plate structure, a plurality of through small holes are uniformly and densely distributed on the second reinforcing component 2, when sound waves are incident to the surface of the second reinforcing component 2, the sound waves enter the interior of the material along the holes, the air in the holes is excited to vibrate, relative motion is generated between the vibrating air and the fixed ribs of the porous material, corresponding viscous resistance is generated in the holes due to the viscosity of the air, the relative motion is forced to generate friction loss and is converted into heat energy, and meanwhile, the heat exchange between the heated compressed air and the solid ribs is heat and conduction.
In this embodiment, first enhancement subassembly 1 is the gypsum material with second enhancement subassembly 2, when having higher intensity, can also reduction in production cost, the shaping of being convenient for during integrative preparation exterior trim panel 11 and support column 12.
Further, the second rock wool board 4 comprises a plurality of wedge-absorbing modules 41, the base 411 of each wedge-absorbing module 41 is glued with the second reinforcing component 2, and the split part 412 of each wedge-absorbing module is close to the wave crest sound-absorbing sponge 6; the crest side of the crest sound absorption sponge 6 is close to the first rock wool board 3.
The sound absorption wedge is a special sound absorber, which applies the principle of gradual transition, when sound waves enter from the tip, due to the gradual transition property of the sound absorption layer, the acoustic impedance of the material can be well matched with that of air, so that high-efficiency absorption is obtained. The wedge absorber has strong capability of absorbing low-frequency sound.
The transmission path of noise in this strenghthened type sound absorption rock wool board does: the exterior finish plate 11 → the first rock wool panel 3 → the gap → the wave crest sound absorbing sponge → the gap → the second rock wool panel 4 → the second reinforcement member 2.
In this embodiment, the wedge acoustic module 41 is preferably of a double-wedge structure, so that the production cost is reduced while the low-frequency noise is effectively absorbed, and it should be noted that the wedge acoustic module 41 may also be of a single-wedge structure or a triple-wedge structure.
In the present embodiment, two adjacent wedge modules 41 are perpendicular to each other to achieve better sound absorption effect.
Further, first rock wool board 3 and second rock wool board 4 are made by fire prevention rock wool, and sound sponge 6 is inhaled by the crest to be made by non-combustible glass fiber cotton to make this strenghthened type inhale the whole inorganic fire-retardant materials of rock wool board, have better fire prevention effect of inhaling.
According to the utility model, the first reinforcing component 1 and the second reinforcing component 2 form a firm frame type structure, and the first rock wool board 3, the wave crest sound absorption sponge 6 and the second rock wool board 4 which have certain gaps are sequentially arranged in the cavity 5 of the frame, the first rock wool board 3 can effectively reduce echoes, the wave crest sound absorption sponge 6 can effectively absorb high-frequency noise, the second rock wool board 4 can effectively absorb low-frequency noise, and air in the gaps between the wave crest sound absorption sponge 6 and the first rock wool board 3 as well as between the wave crest sound absorption sponge 6 and the second rock wool board 4 can also reduce the transmission of noise sound energy to a certain extent, so that the noise passing through the reinforced sound absorption rock wool board is greatly reduced. And, strengthen subassembly 1 and second by the first reinforcing component of gypsum preparation 2, by the first rock wool board 3 and the second rock wool board 4 that fire prevention rock wool made, inhale sound sponge 6 all incombustible by the crest that glass fiber cotton made, possess stronger fire behavior.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
