Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and more specifically, to a reinforced structure for loudspeaker spiders. Background Technology

[0002] The spider is an important component in a loudspeaker. Its outer edge is bonded to the support, and the neck of the spider is bonded to the voice coil. It prevents the voice coil from hitting the iron plate or magnet when it moves within the magnetic gap, and also ensures that the voice coil and the paper cone connected to the voice coil are properly connected and centered.

[0003] Currently, most spiders used are single-wave body designs, meaning the stiffness of the wave body is uniform. Obviously, while ensuring the elasticity of the spider, this single-wave body design can only sacrifice the stiffness of the wave body, resulting in insufficient support strength of the spider for the voice coil, and the speaker is prone to generating noise. This utility model proposes a new solution to the above problems. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a strengthening structure for loudspeaker spiders to solve the technical problems mentioned in the background art.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A reinforced structure for a loudspeaker spider includes a loudspeaker body and a spider. The spider is mounted on a frame inside the loudspeaker body. The spider includes a mounting ring, a first wave body, a second wave body, and a voice coil holder. Multiple sets of the first and second wave bodies are provided. The first wave bodies are fixed at intervals between adjacent sets of second wave bodies. The outermost second wave body is fixed to the inner side of the mounting ring, and the innermost second wave body is fixed to the inner side of the voice coil holder. The vertical distance between adjacent peaks of the first wave body is 1 / 2 to 1 / 5 of the vertical distance between adjacent peaks of the second wave body. The mounting ring is provided with multiple bolt holes, and a conformal guard is bolted to the mounting ring through the bolt holes. The outer side of the innermost second wave body fits against the inner side of the conformal guard.

[0007] Preferably, the mounting ring is provided with a positioning hole, and the lower end face of the conformal edge is provided with a positioning protrusion corresponding to the positioning hole, the positioning protrusion being inserted into the positioning hole.

[0008] In any of the above embodiments, it is preferred that a rubber sealing strip is adhered to the bottom of the mounting ring.

[0009] In any of the above embodiments, it is preferred that the thickness of the first wave body is 2 to 3 times the thickness of the second wave body.

[0010] In any of the above embodiments, it is preferred that the side wall of the mounting ring has a groove, and friction stripes are provided in the groove.

[0011] Compared with existing technologies, the advantages of this utility model are:

[0012] The design of the spring wave in this utility model utilizes a combination of a first wave body and a second wave body to form the main part of the spring wave. By using the two different elastic moduli of the first and second wave bodies, the first wave body mainly provides a certain stiffness, while the second wave body mainly provides a certain elastic deformation. The combination of the two can enhance the overall structural strength of the spring wave. While ensuring its own elastic effect, the spring wave can provide better support for the voice coil, thereby reducing the noise generated by the voice coil. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Example: Please refer to Figures 1 to 2A reinforced structure for a loudspeaker spider includes a loudspeaker body 1 and a spider 2. The spider 2 is mounted on a frame inside the loudspeaker body 1. The spider 2 includes a mounting ring 201, a first wave body 202, a second wave body 203, and a voice coil holder 204. Multiple sets of the first wave body 202 and the second wave body 203 are respectively provided. The first wave body 202 is fixed between adjacent sets of second wave bodies 203 at intervals. The outermost second wave body 203 is fixed to the inner side of the mounting ring 201, and the innermost second wave body 203 is fixed to the inner side of the voice coil holder 204. The vertical distance between adjacent peaks of the first wave body 202 is 1 / 2 to 1 / 5 of the vertical distance between adjacent peaks of the second wave body 203. The mounting ring 201 is provided with multiple bolt connection holes 205. A conformal guard 206 is bolted to the mounting ring 201 through the bolt connection holes 205. The outer side of the innermost second wave body 203 is in contact with the inner side of the conformal guard 206.

[0019] The design of the spider 2 utilizes the combination of the first wave body 202 and the second wave body 203 to form the main part of the spider 2. Through the two different elastic moduli of the first wave body 202 and the second wave body 203, in use, the first wave body 202 mainly provides a certain stiffness, and the second wave body 203 mainly provides a certain elastic deformation. The combination of the two can enhance the overall structural strength of the spider 2. While ensuring its own elastic effect, the spider 2 can provide better support for the voice coil, thereby reducing the noise generated by the voice coil.

[0020] In this embodiment, the mounting ring 201 is provided with a positioning hole 207, and the lower end face of the conformal edge 206 is provided with a positioning protrusion 208 corresponding to the positioning hole 207. The positioning protrusion 208 is inserted into the positioning hole 207. The positioning hole 207 and the positioning protrusion 208 cooperate to facilitate the positioning and installation of the conformal edge 206.

[0021] In this embodiment, a rubber sealing strip 209 is adhered to the bottom of the mounting ring 201; the rubber sealing strip 209 increases the sealing between the mounting ring 201 and the speaker body 1 frame.

[0022] In this embodiment, the thickness of the first wave body 202 is 2 to 3 times the thickness of the second wave body 203; through the above design, the stiffness of the first wave body 202 is much greater than the stiffness of the second wave body 203.

[0023] In this embodiment, a groove 210 is provided on the side wall of the mounting ring 201, and friction stripes are provided in the groove 210; the above design facilitates the installation and removal of the mounting ring 201.

[0024] The working process of this utility model is as follows:

[0025] The spider 2 is mounted on the frame of the speaker body 1. The main part of the spider 2 is formed by the combination of the first wave body 202 and the second wave body 203. With the two different elastic moduli of the first wave body 202 and the second wave body 203, the first wave body 202 mainly provides a certain stiffness and the second wave body 203 mainly provides a certain elastic deformation. The combination of the two can enhance the overall structural strength of the spider 2. While ensuring its own elastic effect, the spider 2 can provide better support for the voice coil, thereby reducing the noise generated by the voice coil.

[0026] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
