[0030] Among them, the outer sound insulation board 1 can be used to initially isolate the external noise, the first damping layer 2 and the second damping layer 6 can play the role of vibration reduction and sound insulation, and the first additional sound insulation board 3 and the second additional sound insulation board 7 can further isolate the noise. At the same time, the perforated plate 10 can be used to absorb the sound from the inside, the protective layer 9 can enhance the sound absorption performance and further enhance the sound insulation effect, and the sound-absorbing cotton 8 can further absorb the sound from the inside. The middle sound insulation board can isolate the sound from the outside and the sound from the inside, and play a two-way sound insulation effect.
[0031] A convex block 11 is provided at the middle end of the lower side of the outer sound insulation board 1, and a groove 12 is provided at the middle end of the upper side of the first damping layer 2. The cooperation between the convex block 11 and the groove 12 can prevent the outer sound insulation board 1 and the first damping layer 2 from being offset, thereby playing a limiting role, so that the outer sound insulation board 1 and the first damping layer 2 can be better fixedly connected by an adhesive.
[0032] Furthermore, the outer sound insulation board 1 is made of metal, and the first damping layer 2 is a rubber structure.
[0033] A convex block 11 is provided at the middle end of the lower side of the first damping layer 2, and a groove 12 is provided at the middle end of the upper side of the first additional sound insulation board 3. The cooperation between the convex block 11 and the groove 12 can prevent the first damping layer 2 and the first additional sound insulation board 3 from being offset, and play a limiting role, so that the first damping layer 2 and the first additional sound insulation board 3 can be better fixed by the damping glue. The damping glue can better play the effect of vibration reduction and noise reduction.
[0034] Furthermore, the first additional sound insulation board 3 and the first and second additional sound insulation boards are FC sound insulation boards or gypsum boards, which can be used to further isolate external sounds.

[0036] Furthermore, the middle sound insulation board 5 and the second damping layer 6 are also fixed by using adhesive, and the second damping layer 6 and the second additional sound insulation board 7 are also fixed by using damping glue.
[0037] Furthermore, the outer sound insulation board 1, the middle sound insulation board 5 and the perforated board 10 are made of metal, and the perforation rate of the perforated board 10 is 20%-30%.
[0038] Furthermore, the thickness of the middle sound insulation board 5 is greater than that of the outer sound insulation board 1 , and the noise from the outer sound insulation board 1 and the noise absorbed by the perforated board 10 can be further isolated by the middle sound insulation board 5 .
[0039] exist Figure 1 to Figure 2 In an optional embodiment, first L-shaped fixing blocks 31 are provided at both ends of the lower side of the first additional sound insulation board 3, and second L-shaped fixing blocks 51 are provided at both ends of the upper side of the middle sound insulation board 5. The first L-shaped fixing block 31 is integrally connected with the first additional sound insulation board 3, and the second L-shaped fixing block 51 is integrally connected with the middle sound insulation board 5. The sound insulation cotton 4 is arranged between the first additional sound insulation board 3 and the middle sound insulation board 5, and the two ends of the sound insulation cotton 4 are respectively matched with the two first L-shaped fixing blocks 31 and the two second L-shaped fixing blocks 51, thereby ensuring that the sound insulation cotton 4 can be better connected with the first additional sound insulation board 3 and the middle sound insulation board 5.
[0040] The outer sound insulation board 1, the first damping layer 2, the first additional sound insulation board 3, the sound insulation cotton 4, the middle sound insulation board 5, the second damping layer 6, the second additional sound insulation board 7, the sound absorbing cotton 8, the face layer 9 and the perforated board 10 have the same length.
[0041] The specific operation steps of a sound insulation board of the utility model are as follows:
[0042] The external sound insulation board 1, the first damping layer 2, the first additional sound insulation board 3 and the sound insulation cotton 4 are used to insulate, eliminate and damp the external sound. The perforated plate 10, the protective layer 9, the sound absorbing cotton 8, the second additional sound insulation board 7 and the second damping layer 6 are used to absorb, insulate, eliminate and damp the sound from the inside. It is ensured that the sound insulation board can well insulate the sound from the outside and the sound from the inside. The first damping layer 2 and the second damping layer 6 can not only damp the vibration of the sound, but also effectively isolate the low-frequency sound from passing through. At the same time, a middle sound insulation board 5 is also provided in the middle of the sound insulation board. The middle sound insulation board 5 is thicker and can further insulate the sound from the outside and the sound from the inside.
[0043] Each functional layer in the sound insulation board is limited by the protrusion 11 and the groove 12, or by the first L-shaped fixing block 31 and the second L-shaped fixing block 51, so as to ensure that the sound insulation board is in an integrated connection, each functional layer can be fixed without displacement, and the installation is convenient.
[0044] The same and similar parts between the various embodiments in this specification can be referenced to each other, and each embodiment focuses on the differences from other embodiments.
