Specifically, (the strength of the sound-absorbing cotton is strengthened by reinforcing the fish skeleton. When the sound-absorbing cotton is squeezed by the outside world, the reinforced fish skeleton will cause a certain degree of bending and deformation. When the outside world stops applying force, the reinforced fish skeleton will push the reinforced sound-absorbing cotton back to its original position, so that it can maintain its shape, which is conducive to use and maintains its beauty. The reinforcement frame is used to maintain the shape of the cork board to avoid it from bending during use).
