[0032] A schematic view of a soundproofing board for interior decoration according to the present application is shown in Figure 1 The soundproofing board for interior decoration comprises an inner board 10 and an outer board 20, and a sound-absorbing assembly 30 is arranged between the inner board 10 and the outer board 20. A first honeycomb board 40 is arranged between the sound-absorbing assembly 30 and the inner board 10, and a second honeycomb board 50 is arranged between the sound-absorbing assembly 30 and the outer board 20.

[0033] In the present application, the inner board 10 and the outer board 20 are relative to the interior. Specifically, the inner board 10 is a board facing the interior, and the outer board 20 is a board facing the interior wall.

[0034] Figure 2 is Figure 1 A partial enlarged view of A in the above figure shows that the aperture of the first honeycomb board 40 is smaller than the aperture of the second honeycomb board 50. The sound in the interior propagates from inside to outside, and the sound becomes smaller and smaller as it propagates. The smaller the aperture of the honeycomb board, the more sound waves it can absorb. Therefore, in the present embodiment, the aperture density of the honeycomb board is set in accordance with the law of sound propagation, which is more conducive to achieving soundproofing under the condition of ensuring the strength of the mechanism.

[0035] Further, the distribution density of the honeycomb grooves in the first honeycomb board 40 is greater than the corresponding distribution density of the second honeycomb board 50. Specifically, the distribution density of the honeycomb grooves in the first honeycomb board 40 is 120-150 cells / cm, and the distribution density of the honeycomb grooves in the second honeycomb board 50 is 60-80 cells / cm, so as to absorb more sound by the honeycomb grooves.

[0052] Figure 7 is the schematic diagram of the sound insulation plate provided by another embodiment of the present application, wherein the orientation of the sound inlet hole 32a of the sound-absorbing body plate 31 is different. And the orientation interval is changed. Specifically, one sound inlet hole 32a is oriented towards the inner plate 10, and the sound inlet hole 32a adjacent thereto is oriented towards the outer plate 20.
