Sound absorption plate
A sound absorption plate comprises a frame and an end cap, wherein the frame comprises a side wall A and a side wall B, the side wall A is provided with sound through holes, polyester fiber cotton plates of the sound through holes with different densities are arranged in the frame at intervals, and the densities of the sound through holes in the polyester fiber cotton plates are sequentially reduced from the side wall A to the side wall B. By means of design of inner oscillation cavities, sound is gradually absorbed by the polyester fiber cotton plates in the oscillation cavities during oscillation, besides, the sound is gradually transferred from high-density polyester fiber cotton plates to low-density polyester fiber cotton plates, and accordingly, sound absorption work can be distributed in different oscillation cavities and the sound absorption effect is better.
