Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: polyester grid abatvoix, including the polyester grid abatvoix body, the polyester grid abatvoix body is including inhaling sound composite interlayer 1, inhale the top fixed surface of sound composite interlayer 1 and connect a plurality of group grid strip 2, be formed with the recess between the adjacent grid strip 2, inhale sound composite interlayer 1 includes base plate 3, the inside fixedly connected with high density polyester fiberboard 4 of base plate 3, the sound groove has been seted up to the inside of high density polyester fiberboard 4, it has the cotton layer 8 of inhaling the sound to inhale the sound inslot packing, still fixedly connected with a plurality of supporting shoe 6 between sound groove top and the bottom, furthermore, can play the effect of support to high density polyester fiberboard 4 through supporting shoe 6, the crushing resistance of whole sound composite interlayer 1 of inhaling has been increased, furthermore, high density polyester fiberboard 4 can absorb medium-high frequency sound 500-2000hz, can diffuse medium-high frequency sound 500-4000hz again, it is effectual to absorb the diffusion, the inside of supporting shoe 6 is provided with inhales sound cotton ball 10.
