[0005] Further, the through holes are inclinedly arranged on the top plate, the bottom plate and the partition plate, and the inclination directions of the through holes on the top plate, the bottom plate and the partition plate are not completely the same.

[0006] Further, the through holes on the top plate and the bottom plate are inclined to the left, and the through holes on the partition plate are inclined to the right.

[0007] Further, the thickness of the upper layer of sound absorption cotton is 2-5mm larger than that of the lower layer of sound absorption cotton.

[0008] Further, the outer surfaces of the top plate and the bottom plate are coated with anti-blocking paint, and the hole blocking rate of the top plate and the bottom plate after coating the anti-blocking paint is ≤5%.

[0009] Further, the shock absorption plate is made of rubber material.

[0010] In order to reduce the weight of the plate type sound absorber, further, the structure of the shock absorption plate is annular structure.

[0011] Beneficial effects: the plate sound absorber with damping function, the plate sound absorber adopts the structure of top plate - upper layer of sound absorbing cotton - partition - lower layer of sound absorbing cotton - damping pad - bottom plate, enhances the sound absorption effect of the plate sound absorber, in addition, by adding the damping plate between the lower layer of sound absorbing cotton and the damping pad, the plate sound absorber has the damping function, avoids the damage of the plate sound absorber due to collision, prolongs the service life of the plate sound absorber.
