[0024] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0025] Embodiment:

[0026] As Figures 1-4 shown, the present invention provides a technical solution for an anti-seismic foam with sound-absorbing effect:

[0027] As shown in the figure, a seismic foam with sound absorption effect, its structure includes a foam body 1, the foam body 1 includes a bottom layer 11, a sound absorption layer 12 provided on the upper surface of the bottom layer 11, a surface layer 13 provided on the upper surface of the sound absorption layer 12, and a rib 14 that cooperates with the upper and lower surfaces of the sound absorption layer 12. The sound absorption layer 12 includes perforations 121 opened on its surface, groove frames 122 provided on the upper and lower surfaces of the sound absorption layer 12 and arranged in a relatively staggered structure, and elastic strips 123 provided inside the groove frames 122. The perforations 121 are filled with sound absorption cotton a1 and sound absorption ring plates a2.

[0028] Ribs 14 are provided on both the upper surface of the bottom layer 11 and the lower surface of the surface layer 13.

[0029] The groove frames 122 are arranged corresponding to the ribs 14 to enhance the high elastic performance inside the foam.

[0030] The lower surface of the bottom layer 11 is provided with a rubber pad and has a rough structure. Through the setting of the rough structure, the vibration at the bottom of the foam is reduced.

[0031] The sound absorption cotton a1 has a granular structure and is made of polyester foam material, which is beneficial to enhancing the absorption of sound.

[0032] The sound absorption ring plate a2 has a silicone cone structure, and circular holes are opened at the protruding positions to reduce the echo of sound.

[0033] Two sound absorption ring plates a2 are provided as a group, and there are two groups in total. The sound absorption ring plates a2 are arranged symmetrically inside the perforations 121 to achieve the absorption of sound, reduction of echo and noise.

[0034] The specific implementation principle is as follows: The surface layer 13 and the bottom layer 11 are sleeved correspondingly, so that the ribs 14 are sleeved correspondingly with the groove frames 122 provided on the surface of the sound absorption layer 12. When the surface layer 13 is subjected to greater force, the ribs 14 and the groove bars 122 are tightly fitted. When the force is no longer applied, under the action of its own elasticity and the elastic strips 123 provided inside the groove section 122, it quickly rebounds to the original state. At the same time, by using the perforations 121 provided on the surface of the sound absorption layer 12, which are filled with sound absorption cotton a1, the absorption of sound can be realized, and with the sound absorption ring plate a2 arranged in a cone structure, the reflux of sound can be reduced.

[0035] The foregoing has shown and described the basic principles, main features and advantages of the present invention. For a person skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and without departing from the spirit or basic features of the present invention, the present invention can be implemented in other specific forms.
