Description

Technical Field

[0001] The utility model relates to the field of speaker net technology, in particular to an improved speaker net punching structure. Background Art

[0002] A speaker is a device that converts audio signals into sound. In simple terms, it is a device that amplifies audio signals and then releases sound so that users can hear the sound. Existing speakers are equipped with speaker nets to protect their internal components. However, since speakers are extremely fragile, there are many factors that can affect the sound quality of speakers. Speakers are used in a variety of scenarios, such as homes, offices, public places, etc. According to different application scenarios, speakers are designed in various strange shapes. Even so, these speakers still cannot do without speaker nets.

[0003] The main structure of the current speaker mesh includes a shell, which is formed by stamping of metal plates, including a main body plate and a connecting plate. A plurality of mesh holes are formed on the main body plate by stamping, and the connecting plate is bent inward and extends from the side edge of the main body plate; in order to record some technical data of the audio manufacturer and rated working conditions, a nameplate fixing area is usually set on the main body plate, and the plurality of mesh holes are distributed around the nameplate fixing area. In order to prevent the nameplate from protruding from the speaker mesh and affecting the appearance and feel, a concave position is generally punched out at the nameplate fixing area so that the nameplate is embedded in the concave position. Since the mesh holes are too close to the concave position, the concave position forming will deform the mesh holes near the concave position and cause poor appearance. In order to solve this problem, the current solution is to punch the mesh holes near the concave position separately after the concave position is formed, which requires four sets of punching dies to be added separately, resulting in more processes, increased mold costs, and thus increased single product costs. Therefore, it is necessary to study a solution to solve the above problems. Utility Model Content

[0004] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide an improved speaker mesh punching structure, which can effectively solve the problem of increased costs caused by the need for additional punching during the production process of the existing speaker mesh.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The plurality of mesh holes are distributed around the nameplate fixing area, and the connecting plate is bent inward and extends from the side edge of the main body plate; the nameplate fixing area is concave outside and convex inside to form a concave position on the outer surface and a boss on the inner surface, and ribs are formed around the opening of the concave position, and pre-punched holes and a plurality of nameplate fixing holes are formed through the bottom surface of the concave position and the surface of the boss, and the plurality of nameplate fixing holes are located around the pre-punched holes.

[0007] As a preferred solution, the concave portion and the convex portion are both in the shape of a square frustum, which has a simple structure, is easy to form, and has a beautiful appearance.

[0008] As a preferred solution, the main body plate is an outwardly convex arc-shaped plate structure with a beautiful appearance.

[0009] As a preferred solution, the nameplate fixing hole is a round hole, and a plurality of nameplate fixing holes are distributed at various corners of the pre-punched hole, which has a simple structure, is easy to form, and avoids deformation.

[0010] As a preferred solution, the mesh is a hexagonal hole, and multiple meshes are densely arranged to ensure the sound effect.

[0011] As a preferred solution, the nameplate fixing area is square and has a beautiful appearance.

[0012] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0013] By providing pre-punching holes and embossing ribs, when forming the concave positions, the use of pre-punching holes and embossing ribs can effectively prevent material pulling, avoid deformation of the mesh holes near the concave positions and cause poor appearance, and there is no need to punch the mesh holes separately after the concave positions are formed, thus saving the punching die, greatly shortening the process, reducing the die cost, thereby reducing the cost of a single product and improving the market competitiveness of the product.
