Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a positioning support structure for a loudspeaker. Background Technology

[0002] Loudspeakers, such as car loudspeakers, typically employ a cone with a spider (also called a centering spider or locating support). During loudspeaker assembly, the voice coil, upper clamp, magnet, and T-iron are first combined to form the magnetic circuit system. Then, the magnetic circuit system is pressed together with the balancer, integrating the magnetic circuit assembly with the balancer as a single unit. Existing loudspeaker spiders, such as... Figure 1 As shown, the positioning plates of loudspeakers are typically made of materials such as Nomex, PC, and cotton cloth. Due to the inherent properties of these materials and their susceptibility to temperature and humidity fluctuations, the positioning plates are prone to deformation. Currently, temperature- and humidity-controlled rooms are used to store the positioning plates to avoid long-term storage, but deformation still often occurs, affecting loudspeaker performance. While new adhesives and molding processes can reduce deformation, it remains somewhat unavoidable. Therefore, a novel loudspeaker positioning plate structure that is less prone to deformation is needed. Utility Model Content

[0003] In view of this, one of the technical problems to be solved by this utility model is to provide a positioning support structure for a loudspeaker.

[0004] According to one aspect of the present invention, a positioning support structure for a loudspeaker is provided, characterized in that it comprises: a positioning support body and an annular edge plate; the positioning support body is an annular corrugated diaphragm, and the annular edge plate is provided at the edge of the positioning support body.

[0005] Optionally, the height of the annular edge plate is greater than or equal to the corrugated height of the positioning support body.

[0006] Optionally, the corrugation height of the annular edge plate is less than that of the positioning support body.

[0007] Optionally, the central hole sidewall of the positioning support body is a conical surface, and the bottom end of the central hole sidewall is lower than the bottom of the corrugations of the positioning support body.

[0008] Optionally, the top of the corrugations on the positioning support body is arc-shaped.

[0009] Optionally, the top of the annular edge plate is provided with a folded edge.

[0010] Optionally, the positioning support body and the annular edge plate are integrally formed.

[0011] The positioning support structure of this utility model provides a positioning support structure that is not easily deformed, thus solving the problem of positioning support deformation; by adding an annular edge plate to the edge of the positioning support, the deformation of the positioning support can be greatly reduced, thereby improving the quality of the loudspeaker.

[0016] The present invention will now be described more fully with reference to the accompanying drawings, which illustrate exemplary embodiments of the present invention. The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The technical solutions of the present invention will now be described in various aspects with reference to the figures and embodiments.

[0017] Existing positioning brackets are prone to deformation. Storing them in a temperature- and humidity-controlled chamber reduces storage time and helps prevent deformation. With advancements in technology, new adhesives and molding processes can also be used to minimize deformation. However, storing positioning brackets in a temperature- and humidity-controlled chamber increases costs and reduces the production efficiency of speaker manufacturers. Adopting new adhesives and molding processes in positioning bracket production significantly increases development costs. If deformed positioning brackets are used in speaker manufacturing, speaker distortion will increase, and there is a risk of poor adhesion and delamination due to positioning bracket deformation.

[0018] like Figure 2 , 3As shown, this utility model provides a positioning support structure for a loudspeaker, including a positioning support body 11 and an annular edge plate 12; the positioning support body 11 is a circular corrugated diaphragm, and the annular edge plate 12 is provided at the edge of the positioning support body 11.

[0019] The positioning support structure of this utility model solves the problem of deformation of the positioning support. The edge of the positioning support is most prone to deformation. By adding an annular edge plate to the edge (outer edge of the adhesive edge) of the positioning support, the annular structure of the annular edge plate has strong stability, which can greatly reduce the deformation of the positioning support.

[0020] In some embodiments, the height of the annular edge plate 12 is greater than or equal to the height of the corrugations 112 of the positioning support body 11. The height of the annular edge plate 12 may also be less than the height of the corrugations 112 of the positioning support body 11. The positioning support body 11 is provided with a central through hole, and the sidewall of the central hole (central through hole) 111 of the positioning support body 11 is a conical surface, with the bottom end of the sidewall of the central hole 111 lower than the bottom of the corrugations 112 of the positioning support body 11.

[0021] For example, the height of the sidewall of the central hole 111 is greater than the height of the corrugation 112 of the positioning support body 11, and the bottom end (i.e. the small end) of the sidewall of the central hole 111 is lower than the bottom of the corrugation 112 of the positioning support body 11, forming a positioning support body with a central hole recessed structure.

[0022] The top of the corrugations 112 of the positioning support body 11 is rounded. The top of the annular edge plate 12 is provided with a folded edge 121. The positioning support body 11 and the annular edge plate 12 can be made of the same material or various existing materials. The positioning support body 11 and the annular edge plate 12 can be integrally formed. The edges of the positioning support body 11 and the annular edge plate 12 can form various angles.

[0023] The positioning support structure of this invention can significantly reduce the deformation of the positioning support, effectively increase its storage time, and improve the production efficiency of speaker manufacturers. It avoids the increased development costs associated with using new adhesives and molding processes in the production of positioning supports. In existing positioning support technologies, when pressing with a tooling after gluing, excess glue easily spills onto the tooling, requiring cleaning after a period of pressing, thus affecting work efficiency. The positioning support structure of this invention protects the tooling from spilled glue, and the outer edge of the positioning support structure is easy to grip, which is beneficial for automated production lines. The cost increase is minimal, and the quality of the speaker is improved.

Any person skilled in the art should understand that the preferred numerical range is merely one among many feasible numerical values ​​that has a more obvious or representative technical effect. Because there are many numerical values, it is impossible to list them all. Therefore, this utility model discloses only some numerical values ​​to illustrate the technical solutions of this utility model. Furthermore, the numerical values ​​listed above should not constitute a limitation on the scope of protection of this utility model.

[0025] Meanwhile, if the present invention discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured by casting) (except where it is obviously impossible to use an integral forming process).
