Due to its unique physical properties, sponge is widely used in various fields, such as home decoration, car interior, electronic products, server packaging, etc. In these fields, sponge can not only provide a comfortable feel and touch, but also effectively absorb sound waves and reduce noise transmission, thereby improving people's living and working environment.

[0003] With the rapid development of information technology, sponge should be widely used in all walks of life due to its soft characteristics. Especially with the continuous development of warehousing and logistics, the application of sponge in packaging materials has gradually increased, and sponge is usually used in sealing, noise reduction and cushioning and shock absorption. Therefore, the corresponding sponge shape is usually used according to needs and bonded to the use area. Through the sound absorption effect of the sponge, the propagation and diffusion of noise can be effectively reduced, the quiet performance of the use environment can be improved, and the soft characteristics of the sponge can also play a role in buffering and protecting the bonded items.

[0004] However, the existing sound insulation sponge absorbs and reduces noise by means of a pyramid-shaped sound-absorbing panel arranged on the surface, but the sound absorption structure of the existing sound-absorbing sponge is very simple, and the sound absorption and noise reduction capacity of the sound-absorbing panel with a peak-shaped sound-absorbing block arranged on the surface is limited, resulting in poor sound insulation and noise reduction effect of the sponge, which is difficult to meet people's growing demand for noise reduction, and the existing sponge has poor structural fire resistance. Once a fire occurs, as the fire spreads, the objects wrapped with the sponge product may be burned, and the existing sponge is easy to burn when encountering an open flame and accelerates the spread of the fire, posing a threat to the safety of the sponge, thereby affecting the safe use of the sponge.

The external noise can be absorbed through the sound-absorbing holes and transmitted through the sound-absorbing holes to the sound-absorbing grooves and the sound-absorbing protrusions of the sound-absorbing plate, so that the sound waves are reflected and consumed, thereby achieving the purpose of reducing noise.

[0009] Further in the above description, a plurality of through holes are opened on the surface of the sponge base layer, and reinforcing ribs are filled in the through holes. The reinforcing ribs are filled in the sponge base layer so that the structural strength of the sponge can be enhanced.
