Description

Technical Field

[0001] This utility model relates to the field of speaker assembly technology, and in particular to a magnetic T-shaped bracket assembly fixture. Background Technology

[0002] Currently, a speaker unit includes components such as a spring, diaphragm, bracket, magnet, T-iron, and voice coil. Among these, the magnetic circuit system is the "heart" of the speaker, and its performance directly determines key parameters such as the speaker's sensitivity, distortion, and power handling capacity. Typically, the magnetic circuit system is composed of a T-iron, magnet, and bracket coaxially bonded together to provide a stable magnetic field for the movement of the voice coil. Therefore, ensuring that these three components have extremely high coaxiality, perpendicularity, and strong bonding strength is one of the most critical process steps in speaker manufacturing.

[0003] The assembly of existing T-iron, magnets, and brackets still largely relies on manual operation. The specific process is as follows: the operator first applies glue to the corresponding magnet mounting position on the T-iron, then manually places the magnet on the center post of the T-iron and applies glue to the upper surface of the magnet. Finally, the bracket is roughly aligned and placed on top, and pressure is applied to perform the pressing assembly operation. However, this cannot accurately guarantee that the central axes of the T-iron, magnets, and brackets are aligned. Slight eccentricity or tilt will cause uneven magnetic gap, which will cause the voice coil in the subsequent speaker unit to be subjected to unbalanced magnetic force during the movement, resulting in problems such as distortion and abnormal noise in the speaker unit, affecting the product's sound quality and yield rate.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a magnet T-iron bracket assembly fixture. It utilizes the matching connection between the T-iron and the connecting part, the magnet and the positioning groove, and the bracket and the first step surface to achieve the central axis coincidence of the T-iron, the magnet, and the bracket during assembly, thereby ensuring the magnetic field balance of the magnetic circuit system, ensuring the stable use of the voice coil in subsequent products, simple operation, convenient assembly, and conducive to improving product quality and pass rate. It has good usability and a wide range of applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A magnet T-iron bracket assembly fixture includes a lower mold base. The upper end of the lower mold base is provided with a first positioning step for positioning the bracket. The first positioning step is provided with a positioning groove for positioning the magnet. The positioning groove is located at the center of the first positioning step. The inner end face of the positioning groove is provided with a connecting part for supporting and connecting the T-iron.

[0008] In use, first install the T-iron on the connecting part and apply glue to the T-iron. Then place the magnet on the positioning groove and stick it to the T-iron for positioning. Then apply glue to the magnet. Finally, place the bracket on the first positioning step and stick it to the magnet for positioning.

[0009] As a preferred embodiment, the positioning groove is provided with a second positioning step for positioning in contact with a magnet.

[0010] As a preferred embodiment, the upper edge of the positioning groove is provided with a first guide slope, which extends obliquely inward from top to bottom.

[0011] As a preferred embodiment, the connecting portion has a tapered structure.

[0012] As a preferred embodiment, the lower mold base is provided with a limiting part for limiting contact with the bracket.

[0013] As a preferred embodiment, four limiting parts are provided, which are located at the four upper corners of the lower mold base.

[0014] As a preferred embodiment, the upper end of the limiting part is provided with a second guide slope on the side near the first positioning step, and the second guide slope extends obliquely downward from the outside to the inside.

[0015] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly achieves the central axis of the T-iron, magnet, and bracket by matching and connecting the T-iron with the connecting part, the magnet with the positioning groove, and the bracket with the first step surface through the design of each component. This ensures the magnetic field balance of the magnetic circuit system, ensures the stable use of the voice coil in the subsequent product, is simple to operate, easy to assemble, and helps to improve the quality and pass rate of the product. It has good usability and a wide range of applications.

[0016] Secondly, the second positioning step is set to support and limit the magnet on the positioning groove, so as to facilitate the subsequent installation and use of the bracket. At the same time, the first guide slope is set to facilitate the guiding assembly between the magnet and the positioning groove.

[0017] Furthermore, the setting of the limiting part realizes the limiting of both sides of the bracket on the lower mold base, so as to avoid the offset problem of the bracket, magnet and T-iron during subsequent press-fitting, and ensure the assembly quality of the bracket, magnet and T-iron. At the same time, the setting of the second guide slope is conducive to the guiding assembly between the bracket and the first positioning step.

[0024] Please refer to Figures 1 to 3 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0025] A jig for assembling a magnet T-shaped bracket includes a lower mold base 10. The upper end of the lower mold base 10 is provided with a first positioning step 11 for positioning a bracket 16. The first positioning step 11 is provided with a positioning groove 12 for positioning a magnet 15. The positioning groove 12 is located at the center of the first positioning step 11. The inner end face of the positioning groove 12 is provided with a connecting part 13 for supporting and connecting a T-shaped bracket 14. The lower end of the T-shaped bracket 14 is provided with a recess 141 for matching the connecting part.

[0026] A positioning post 18 is also provided. The magnet 15 and the bracket 16 are provided with clearance holes 17 corresponding to the center post 142 of the T-iron 14. The upper end of the center post 142 of the T-iron 14 passes through the clearance hole 17 of the magnet 15 and is exposed. The positioning post 18 is detachably installed on the upper end of the center post 142 of the T-iron 14.

Next, assemble the positioning post on the center post of the T-iron. Then apply glue to the magnet. Finally, place the bracket on the first positioning step and bond it to the magnet for positioning. The positioning post passes through the clearance hole of the bracket. In this way, through the design of each component, the T-iron and the connecting part, the magnet and the positioning groove, and the bracket and the first step surface are matched and connected to achieve the central axis of the T-iron, the magnet, and the bracket to be aligned. This ensures the magnetic field balance of the magnetic circuit system. At the same time, the setting of the positioning post helps the user to confirm the central axis of the T-iron, the magnet, and the bracket, which helps to ensure the stable use of the voice coil in the subsequent product. The operation is simple, the assembly is convenient, and it helps to improve the quality and pass rate of the product. It has good usability and a wide range of applications.

[0028] Furthermore, the positioning groove 12 is provided with a second positioning step 121 for contacting and positioning with the magnet 15.

At the same time, the first guiding slope is provided to facilitate the guiding assembly between the magnet and the positioning groove.

[0029] Furthermore, the connecting part 13 has a conical structure, and correspondingly, the recess 141 is a conical groove. It should be noted that the lower end of the T-iron is mostly flat, and a pad with a connecting hole needs to be installed at the lower end of the T-iron. The connecting hole is matched and connected with the connecting part to realize the positioning connection of the central axis of the T-iron on the lower mold base.

[0030] Furthermore, the lower mold base 10 is provided with a limiting part 19 for contacting and limiting the bracket 16. Specifically, the upper end of the limiting part 19 is provided with a second guide slope 191 on the side near the first positioning step. The second guide slope 191 extends obliquely downward from the outside to the inside. Preferably, four limiting parts 19 are provided, and the four limiting parts 19 are provided at the four corners of the upper end of the lower mold base 10. In this way, the setting of the limiting part realizes the limiting of both sides of the bracket on the lower mold base, so as to avoid the problem of misalignment of the bracket, magnet and T-iron during subsequent pressing, and ensure the assembly quality of the bracket, magnet and T-iron. At the same time, the setting of the second guide slope is conducive to the guiding assembly between the bracket and the first positioning step.

[0031] The key design feature of this utility model is that it mainly utilizes the design of each component to match and connect the T-iron with the connecting part, the magnet with the positioning groove, and the bracket with the first step surface, so as to achieve the central axis of the T-iron, the magnet, and the bracket to be aligned and assembled, thereby ensuring the magnetic field balance of the magnetic circuit system, ensuring the stable use of the voice coil in subsequent products, simple operation, convenient assembly, which helps to improve the quality and pass rate of products, has good usability, and a wide range of applications.

[0032] Secondly, the second positioning step is set to support and limit the magnet on the positioning groove, so as to facilitate the subsequent installation and use of the bracket. At the same time, the first guide slope is set to facilitate the guiding assembly between the magnet and the positioning groove.

[0033] Furthermore, the setting of the limiting part realizes the limiting of both sides of the bracket on the lower mold base, so as to avoid the offset problem of the bracket, magnet and T-iron during subsequent press-fitting, and ensure the assembly quality of the bracket, magnet and T-iron. At the same time, the setting of the second guide slope is conducive to the guiding assembly between the bracket and the first positioning step.

[0034] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
