[0035] Working principle: The sound-absorbing cotton 10 is located between the first base plate 9 and the second base plate 13, and the sound-absorbing cotton 10 itself has a porous structure and other characteristics. When external sound enters, the sound causes the air in the sound-absorbing cotton 10 to vibrate and the sound wave interacts with the fibers, etc. of the sound-absorbing cotton 10, and a part of the sound energy is converted into heat energy and other forms of energy, thereby realizing the absorption of sound, reducing the reflection and propagation of sound, and achieving the effect of noise reduction. The strip-shaped noise reduction groove 8 fixedly connected on the first base plate 9 is in contact with the inner wall of the fireproof plate 1 at the top, when the sound wave enters the strip-shaped noise reduction groove 8, the sound wave will continuously reflect and refract in the groove, and the sound waves interfere with each other, so that the energy of the sound waves is consumed in this complex propagation process, thereby reducing the intensity of the sound wave propagating outward, and assisting in playing a noise reduction role.
