Document Type and Number:
WIPO Patent Application WO/2024/000819
Kind Code:
A1
Abstract:
Disclosed in the present invention is a damping mesh cloth. The damping mesh cloth comprises at least two first wire diameters and at least two second wire diameters, wherein the first wire diameters and the second wire diameters are arranged in a cross-woven manner; each first wire diameter comprises a first circular wire diameter having a circular cross section and two first protrusions formed by respectively extending outwards from two opposite sides of the first circular wire diameter; each second wire diameter comprises a second circular wire diameter having a circular cross section and two second protrusions formed by respectively extending outwards from two opposite sides of the second circular wire diameter; and the two first protrusions located on the sides of two adjacent first wire diameters close to each other and the two second protrusions located on the sides of two adjacent second wire diameters close to each other jointly define an air hole. According to the present invention, under the condition that the weaving density of the wire diameter is not increased, the area of the air hole is reduced, thereby improving the acoustic resistance, and effectively reducing the production cost.
