The present application relates to the technical field of electro-acoustic conversion, in particular to a damping mesh adopted in sounding devices.
With the advent of the mobile internet era, the replacement of electronic products is getting faster and faster, and people have higher and higher requirements for the performance of electronic products in all aspects, one of which is high-quality music functions. Therefore, it is necessary for sounding devices to continuously improve their performance, and high-quality sounding devices are one of the prerequisites for realizing the high-quality music function. A damping mesh attached to a sound outlet hole of the sounding device is one of the important factors for adjusting the sound quality.
In the related art, the damping mesh is woven by using a plurality of wires with circular cross-sections, so as to form a mesh with a plurality of air-permeable micropores, thereby achieving an effect of sound resistance and improve the sounding performance of the sounding device.
However, in the damping mesh of the related art, the distance between the adjacent wires is the same. Since a cross section of the wires is circular, an acoustic resistance formed among the wires is fixed. In order to improve the acoustic resistance of the damping mesh, it is necessary to increase a density of weaved wire, thereby increasing the cost of weaving.
Therefore, it is necessary to provide a new damping mesh to solve the above technical problems.
An object of the present application is to overcome the above technical problems and provide a damping mesh with low cost and high acoustic resistance.
In order to achieve the above object, an embodiment of the present application provides a damping mesh, comprising:
In one embodiment, the first wires are arranged perpendicular to the second wires.
In one embodiment, the first wire further comprises a first flat portion connecting the two first protrusion portions, and the first flat portion is coincided with an outer circumference of the first circular wire.
In one embodiment, the first circular wire, the first protrusion portion and the first flat portion are formed as an integral structure.
In one embodiment, the second wire further comprises a second flat portion connecting the two second protrusion portions, and the second flat portion is coincided with an outer circumference of the second circular wire.
In one embodiment, the second circular wire, the second protrusion portion and the second flat portion are formed as an integral structure.
In one embodiment, the ventilation hole is a square structure
In one embodiment, the first protrusion portion and the second protrusion portion are both arranged in an arc-shaped structure.
In one embodiment, the first wires and the second wires have the same structure.
In one embodiment, the first wires are arranged at equal intervals, and the second wires are arranged at equal intervals.
Compared with the prior art, in the damping mesh of the present application, the first wire parallel to a first direction comprises a first circular wire with a circular cross-section and first protrusion portions formed by opposite sides of the first circular wire along the second direction extending outward, the second wire comprises a second circular wire with a circular cross-section and second protrusion portions formed by opposite sides of the second circular wires along the first direction extending outward, so as to increase a width of the first wires along a direction parallel to the first direction and a width of the second wires along a direction parallel to the first direction. Therefore, on an adjacent side of the two first wires and the two second wires that are adjacent to each other and interlacedly weaved, an area of the ventilation hole jointly enclosed by the two first protrusion portions and the two second protrusion portions is reduced, and an effect of densifying the damping mesh is achieved without increasing the weaving density of the wires, thereby achieving the object of increasing the sound resistance and effectively reducing the production cost.

Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
The present application provides a damping mesh, including at least two first wires 1 parallel to a first direction and spaced apart along a second direction, and at least two second wires 2 parallel to the second direction and spaced apart along the first direction. the first wires 1 and the second wires 2 are interlacedly weaved with each other. Each first wire 1 includes a first circular wire 11 with a circular cross-section and the first protrusion portions 12 formed by opposite sides of the first circular wire 11 along the second direction extending outward. The two adjacent first wire 1 are both provided with a first protrusion portion 12 on a side that the two adjacent first wires 1 are close to each other. Each second wire 2 includes a second circular wire 21 with a circular cross-section and second protrusion portions 22 formed by opposite sides of the second circular wire 21 along the first direction extending outward. The two adjacent second wires 2 are both provided with a second protrusion portions 22 on a side that the two adjacent second wires 2 are close to each other. Two adjacent first wires 1 and two adjacent second wires 2 are interlacedly weaved with each other, so that the two first protrusion portions 12 located on a side of two adjacent first wires 1 that are close to each other and the two second protrusion portions 22 located on a side of two adjacent second wires 1 that are close to each other together form a ventilation hole 3.
The number of the first wires 1 and the number of the second wires 2 may also be 3, 4, 5. A plurality of first wires 1 is arranged perpendicular to a plurality of second wires 2 to weave and form a dashing mesh.

The second wire 2 parallel to the second direction is set as a second circular wire 21 with a second protrusion portions 22 formed by opposite sides of the second circular wire 2l along the first direction extending outward, so that a thickness of the first wires 1 and a thickness of the second wires 2 along a direction perpendicular to the damping mesh remains unchanged, that is, a thickness of the mesh cloth remains unchanged. The first protrusion portions 12 increases a width of the first wires 1 along a direction parallel to the Y-axis, the second protrusions 22 increase a width of the second wires 2 along a direction parallel to the X-axis. Therefore, On the sides of the two first wires 1 and the two second wires 2 that are adjacent and interlacedly woven, an area of the ventilation hole enclosed by the two first protrusion portions 12 and the two second protrusion portions 22 is reduced. That is, by increasing the width of the first wires 1 and the width of the second wire 2, when weaving damping mesh 100 with the same area and the same number of wires, the area occupied by the wires is increased, and the area of the ventilation holes 3 is reduced.

In this embodiment, each second wire 2 further includes a second flat portion 23 connecting the two second protrusion portions 22, and the second flat portion 23 is coincided with an outer circumference of the second circular wire 21. The arrangement of the two second flat portions 23 can increase the overall contact area of the mesh, which facilitates the mounting and fixation of the mesh.
In this embodiment, the second circular wire 21, the second protruding portion 22 and the second flat portion 23 are integrally formed. The integral structure molding arrangement enables high structural strength and saves the cost.
In this embodiment, the ventilation holes 3 have a square structure. The ventilation holes 3 with the square structure are evenly distributed, and the effect of increasing the sound resistance is good.
In one embodiment, the square structure is square, and the ventilation is uniform.
In this embodiment, the first protrusion portion 12 and the second protrusion portion 22 are both provided with an arc-shaped structure 4, which is convenient to increase an overall width of the wire, increase an area occupied by the wires, reduce the permeability area is reduced, and obtain a higher sound resistance.
In this embodiment, the structure of each first wire 1 and the structure of the second wire 2 are the same. The damping mesh 100 formed after weaving in this way has high strength and good use effect.
