As shown in fig. 1 to 4, a sound insulation aluminum veneer 1 comprises an aluminum veneer 1 body, the aluminum veneer 1 comprises an inner plate 11 and an outer plate 12 which are connected with each other, a reflecting plate 2 is arranged between the inner plate 11 and the outer plate 12, the surfaces of the reflecting plate 2 corresponding to the inner plate 11 and the outer plate 12 are recessed to form a silencing groove 21, and a silencing layer 3 is arranged at the gap between the reflecting plate 2 and the inner plate 11 and the outer plate 12. The interference effect can be increased by the reflection of the reflecting plate 2, so that the sound waves are mutually offset and the sound intensity is weakened, and the sound insulation effect of the aluminum veneer 1 is improved.

In order to better improve the interference phenomenon of the sound wave, in the embodiment, the inside of the reflection plate 2 is hollow, and it should be noted here that the inside of the reflection plate 2 can be in a vacuum state, so that the transmission distance of the sound wave is greatly blocked, and the intensity of the sound wave is reduced; the reflecting plate can also be arranged in the cavity and filled with air, which is beneficial to production and manufacture, and ensures the balance of the internal and external air pressure of the reflecting plate 2, thereby ensuring the service life and the reflecting effect of the reflecting plate 2; or the reflecting plate 2 is further filled with sound insulation material to further absorb sound waves, so that the intensity of the sound waves is reduced, and the sound insulation effect is improved.

In this embodiment, as shown in fig. 1 and fig. 2, six faces of the reflection plate 2 are provided with the silencing grooves 21, so that sound waves at different angles can be silenced, the comprehensiveness of silencing is improved, the silencing grooves 21 are provided with a plurality of staggered grooves which are tangentially arranged on the reflection plate 2, and the staggered grooves are arranged in the same area to increase the number of the silencing grooves 21, so that the silencing effect in a unit area can be improved, and the sound insulation effect can be improved.

In this embodiment, the amortization groove 21 is coniform, the cross-section of amortization groove 21 is the triangle-shaped, and the notch area of amortization groove 21 is greater than the groove bottom area, through making the sound wave that gets into in a large amount of amortization grooves 21, the cell wall of amortization groove 21 is touch at the in-process that advances of getting into, thereby take place the reflection, take place the interference phenomenon each other, thereby the sound intensity of sound wave has been weakened greatly, and the distance of notch to cell bottom constantly contracts, make the frequency and the intensity of interference between the sound wave progressively increase, make the sound wave that comes from amortization layer 3 transmission constantly lose, sound intensity descends, thereby make aluminium veneer 1 have good syllable-dividing effect.

In another embodiment, as shown in fig. 3 and 4, for the convenience of processing, the silencing groove 21 is hemispherical, the cross section of the silencing groove 21 is hemispherical, and the hemispherical silencing groove 21 can generate a cancellation interference phenomenon, and simultaneously, the sound wave at the position on the spherical axis is enhanced, so that the enhanced sound wave is reflected to the silencing layer 3, and is not conducted inwards, and the sound insulation effect of the aluminum veneer 1 is improved.

The sound insulating layer in the present embodiment is, but not limited to, a porous material such as an organic fiber material, a hemp-cotton felt, an inorganic fiber material, a glass wool, a rock wool, a foam, or a plastic.

The principle of the embodiment of the application is as follows: in the process of sound transmission, firstly, sound passes through the outer plate 12 of the aluminum veneer 1, the sound-proof layer absorbs and weakens the sound wave intensity, when the sound is transmitted to the sound-proof groove 21 of the reflecting plate 2, a reflection phenomenon is generated in the sound-proof groove 21, the sound wave intensity is further reduced, after the sound passes through the reflecting plate 2, the sound intensity is weakened by the sound-proof layer in an absorbing way, finally, the sound is transmitted out from the inner plate 11 of the aluminum veneer 1, and through a series of sound deadening, the finally transmitted sound intensity is greatly weakened, so that the sound-proof requirement of people on the aluminum veneer 1 is met.

The embodiments of the present invention are preferred embodiments of the present application, and the protection scope of the present application is not limited thereby, wherein like parts are denoted by like reference numerals.
