[0024] The sound insulation layer 5 is composed of sound insulation cotton, which can effectively absorb and block noise from the outside, while reducing the spread of indoor sound, thereby providing a quieter and more comfortable environment for residents.

[0025] The sound-absorbing layer 3 is made of sound-absorbing foam, which is usually composed of soft foam layers. These foam layers can absorb sound waves and reduce sound reflection, thereby reducing indoor echo and noise.

[0026] The base layer 9 is gypsum or fiberboard, which is usually used as the basic treatment layer of the wall, which helps to improve the flatness and moisture resistance of the wall. The base layer 9 is generally made of cement, gypsum powder and water mixed in a certain proportion.

[0030] The blocks 12 provided on the outer wall of the side panel 10 are all distributed in a mirror image with the center of the pin 1.
