Description

Technical Field

[0001] This utility model relates to the field of loudspeaker device technology, specifically to a polygonal external magnetic dome. Background Technology

[0002] A loudspeaker typically includes a magnetic dome, which connects to the cone, magnet, magnetic sheet, etc. Common magnetic domes are trough-shaped with a raised bottom. Common methods for forming magnetic domes include cutting a single piece of magnetic material into a bowl shape. This method has high requirements for the size of the raw material. In addition, the magnetic dome has a monolithic structure, which is not convenient for heat dissipation and needs to be improved. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a polygonal external magnetically conductive bowl, including a grooved main body and a protrusion protruding from the middle of the bottom of the groove. The main body includes a base plate and a side plate connected to the base plate. The side plate is annular with the protrusion located in the opening of the annulus. The side plate includes a split body, a hook body, and a fixing ring. The hook body is provided on the bottom side of the split body with the hook end facing upward. The bottom side of the base plate has a groove 1 spaced circumferentially, and a groove 2 is provided on the peripheral wall of the protrusion corresponding to the groove 1. The bottom end of the split body is embedded in the groove 1, and the hook body is embedded in the groove 2. The fixing ring is sleeved on the protrusion, and part of the fixing ring is embedded in the gap between the hook end of the hook body and the side of the split body. The thickness of the fixing ring is less than the height of the protrusion and the split body.

[0005] This magnetic bowl has an assembled structure. The side plates in the magnetic bowl are assembled in separate parts. This configuration reduces the requirements for raw materials. The spaced-apart parts form the side plates. The gaps between the parts help dissipate heat and reduce weight and material usage. The hook body connected to the parts is located in the groove 2 on the peripheral wall of the protrusion. The hook body is fixed to the protrusion by the fixing ring fitted on the protrusion and the gap between the hook end and the side of the parts, which facilitates the assembly and molding.

[0006] Furthermore, the top end of the protrusion is formed with a groove three and the bottom end is formed with a groove four.

[0007] Furthermore, the hook body is L-shaped, with the horizontal end of the hook body connected to the side of the split body, and the vertical end of the hook body serving as the hook end, which helps to simplify the structure and facilitate molding and assembly.

[0008] Furthermore, the hook body and the split body are integrally formed, which facilitates the molding process.

[0009] Furthermore, the side of the split part facing away from the convex part is a downwardly inclined slope.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model changes the magnetic bowl to an assembled structure, which reduces the requirements for molding materials and helps to reduce costs. The gaps between the parts also help to improve heat dissipation performance, and can further reduce costs. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figure 1 , Figure 2 As shown, in this example, the polygonal external magnetic bowl includes a groove-shaped main body 1 and a protrusion 11 protruding outward from the middle of the groove bottom of the main body 1. The main body 1 includes a base plate 12 and a side plate 2 connected to the base plate 12. The main body 1 is a common T-shape, with the horizontal end of the main body 1 being the base plate 12 and the vertical end of the main body 1 being the protrusion 11. The protrusion is like a common column shape. The main body 1 is integrally formed from magnetically conductive material. The side plate 2 is annular, and the protrusion 11 is located in the annular opening. The peripheral wall of the protrusion in the main body 1 is spaced apart from the inner annular wall of the side plate 2 by a predetermined distance. Preferably, a groove three 13 is formed at the top end of the protrusion 11, and a groove four 14 is formed at its bottom end.

[0020] In this example, the side plate 2 is an assembly type, specifically including a split body 20, a hook body 22, and a fixing ring 21. The split body 20 is like a common rectangular block. The bottom side of the split body 20 has a hook body 22 integrally formed. The hook end of the hook body 22 faces upward. The hook body 22 is like a common L-shape. The horizontal end of the hook body 22 is connected to the bottom side of the split body 20, and the vertical end of the hook body 22 is the hook end.

[0021] In this example, a groove is formed circumferentially at intervals along the side of the base plate 12. Groove 1 extends radially, and groove 2 is formed on the peripheral wall of the corresponding protrusion. Groove 1 is used to mate with the bottom end of the split body 20, and groove 2 is used to mate with the hook body 22. During installation, the bottom end of the split body 20 is inserted into groove 1, and the hook body 22 is simultaneously inserted into groove 2. The fixing ring 21 is fitted onto the protrusion 11, and the inner diameter of the fixing ring is consistent with the outer diameter of the protrusion. Part of the fixing ring 21 is inserted into the gap between the hook end of the hook body 22 and the side of the split body 20, thereby fixing the split body and the main body together. Furthermore, the thickness of the fixing ring 21 is less than the height of the protrusion and the split body 20, so that above the fixing ring, the peripheral wall of the protrusion in the split body and the main body is spaced apart. Preferably, the side of the split body facing away from the protrusion is shaped as a downwardly inclined slope 23.

[0022] Regarding the number of parts, such as five, six, etc., Figure 1 As shown, the split parts 20 are evenly distributed around the protrusion 11, and the gaps between the split parts 20 facilitate heat dissipation. This split assembly structure helps to reduce weight and lower the requirements for raw materials.

[0023] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
