[0006] As a preferred embodiment, the surface of the pyramid is provided with a glass wool layer, and a protruding block is arranged on the glass wool layer. The glass wool layer is a porous sound absorption material, and the sound is dissipated due to air viscous effect and internal reflection when contacting the glass wool layer, thereby further improving the sound insulation effect.

[0007] As a preferred embodiment, the main plate and the back plate are both high-density composite boards, and a damping coating is coated on the outer wall of the main plate. The damping coating is a special material for reducing vibration and noise, which is usually coated on the surface of the wall, sound insulation board, metal or composite material to reduce structural vibration and solid sound transmission, thereby improving the sound insulation effect.

[0008] As a preferred embodiment, the inner wall of the honeycomb tube is provided with a sound absorption block, and a plurality of sound absorption blocks are uniformly arranged. The plurality of sound absorption blocks can make the sound repeatedly reflect and consume in the honeycomb tube.

[0009] As a preferred implementation, the upper part of the micro-hole is flared to facilitate more sound entering from the micro-hole.

[0011] Compared with the prior art, the utility model has the advantages and positive effects that,

[0012] When sound enters the main plate, part of the sound is directly reflected back to reduce the amount of noise entering, and the other part of the sound wave penetrates the main plate and a cork layer to enter the sound insulation layer. The sound enters the interior from the micro-holes of the sound insulation layer and is reflected multiple times between the honeycomb cavity, the pyramid and the sound absorption groove, so that part of the sound wave energy is converted into heat energy. The glass wool layer on the surface of the pyramid is a porous sound-absorbing material. When the sound contacts the glass wool layer, the sound is dissipated due to air viscosity effect and internal reflection, further improving the sound insulation effect. The inclined top of the pyramid top is arranged to directly reflect the sound entering the honeycomb cylinder on the inner wall of the honeycomb cylinder, thereby reducing the possibility of the sound directly reflected from the sound absorption groove after impacting the top of the pyramid. If some residual sound penetrates the sound insulation layer, the sound can be further consumed by another layer of cork layer. The remaining sound impacts the back plate and is reflected. The high-density material greatly reduces the transmission of sound, forming a final sound insulation barrier. BRIEF DESCRIPTION OF DRAWINGS
