Description

Technical Field

[0001] This utility model relates to the field of loudspeakers, and in particular to a loudspeaker assembly. Background Technology

[0002] The magnetic circuit components of existing loudspeakers generally include a washer, a magnet, and a T-iron. Currently, the magnetic circuit components are usually glued together with adhesive, and then the magnetic circuit components are assembled and connected to the speaker frame. This manufacturing process is inefficient because it requires applying adhesive and waiting for the adhesive to cure, and there is a risk that the washer, magnet, and T-iron may fall off due to adhesive aging. Furthermore, if the adhesive used is of poor quality, it may be harmful to human health.

[0003] In view of the above problems, it is necessary to study a loudspeaker assembly that is highly efficient in production and has a stable structure. Utility Model Content

[0004] The purpose of this invention is to provide a loudspeaker assembly that has high production efficiency and stable structure.

[0005] To achieve the above objectives, the solution of this utility model is: A loudspeaker assembly includes a frame and a magnetic circuit assembly; the magnetic circuit assembly includes a washer, a magnet and a T-iron stacked sequentially, with the washer and magnet fitted over an intermediate column of the T-iron; the frame has a connecting portion that is glued to the magnetic circuit assembly, the connecting portion covering the outer peripheral walls of the washer, magnet and T-iron, and the connecting portion also covering the end face of the washer and the end face of the T-iron.

[0006] The washer, magnet, and T-iron of the magnetic circuit assembly are arranged coaxially.

[0007] The magnetic circuit assembly is coaxially arranged with the basin frame.

[0008] The connecting part of the basin frame forms an inner ring groove. The inner peripheral wall of the inner ring groove is attached to the outer peripheral wall of the washer, the magnet and the T-iron. The inner end faces of the two ends of the inner ring groove are attached to the end face of the washer and the end face of the T-iron, respectively.

[0009] The connecting part of the basin frame is also provided with multiple through openings that communicate with the inner ring groove.

[0010] By adopting the above solution, this utility model directly combines the speaker frame with the washer, magnet, and T-iron of the magnetic circuit assembly through an overmolding process. This allows for direct bonding of the speaker frame with the washer, magnet, and T-iron during injection molding, effectively improving the production efficiency of the speaker assembly. Furthermore, the washer, magnet, and T-iron of the magnetic circuit assembly do not require adhesive bonding, avoiding the drawbacks of existing adhesive connections. Additionally, the connecting portion of the speaker frame covers the outer peripheral walls of the washer, magnet, and T-iron of the magnetic circuit assembly, and also covers the end faces of the washer and T-iron. This ensures stable positioning of the magnetic circuit assembly within the speaker frame, resulting in a secure connection between the frames and thus a stable speaker assembly structure.

[0020] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0021] like Figures 1 to 3 As shown, this utility model discloses a loudspeaker assembly A, which includes a frame 1 and a magnetic circuit assembly 2; the magnetic circuit assembly 2 includes a washer 21, a magnet 22 and a T-iron 23 stacked in sequence, with the washer 21 and the magnet 22 fitted onto the T-iron 231 of the T-iron 23; the frame 1 has a connecting part 11 that is glued to the magnetic circuit assembly 2, the connecting part 11 covers the outer peripheral wall of the washer 21, the magnet 22 and the T-iron 23, and the connecting part 11 also covers the end face of the washer 21 and the end face of the T-iron 23.

[0022] As described above, this invention directly combines the frame 1 with the washer 21, magnet 22, and T-iron 23 of the magnetic circuit assembly 2 through an encapsulation method. This allows the frame 1 to be directly combined with the washer 21, magnet 22, and T-iron 23 of the magnetic circuit assembly 2 during injection molding, effectively improving the production efficiency of the speaker assembly A. Furthermore, the washer 21, magnet 22, and T-iron 23 of the magnetic circuit assembly 2 do not require adhesive bonding, thus avoiding the disadvantages of existing adhesive connections. Additionally, the connecting portion 11 of the frame 1 covers the outer peripheral walls of the washer 21, magnet 22, and T-iron 23 of the magnetic circuit assembly 2, and also covers the end faces of the washer 21 and T-iron 23. This ensures that the frame 1 stably holds the magnetic circuit assembly 2, resulting in a secure connection between the frame 1 and the speaker assembly A, and consequently, a stable structure for the speaker assembly A.

[0023] Cooperate Figures 4 to 8 As shown, this utility model also discloses a method for manufacturing the speaker assembly A of this utility model, which includes the following steps: Step 1: Stack the washer 21, magnet 22 and T iron 23 in sequence to obtain the magnetic circuit assembly 2, and the washer 21 and magnet 22 are fitted onto the T iron 231 of the T iron 23; Step 2: Install the positioning fixture C on the magnetic circuit assembly 2. The positioning fixture C ensures that the washer 21 and the T-shaped iron 23 are coaxially positioned. Step 3: The magnetic circuit assembly 2 with the positioning fixture C installed is installed into the lower mold B1 of the basin frame injection mold B, and the lower mold B1 positions the magnetic circuit assembly 2, so that the washer 21, magnet 22 and T iron 23 are coaxially set with the lower mold B1, and the magnetic circuit assembly 2 is suspended. Step 4: Connect the upper mold B2 and the lower mold B1 of the basin frame injection mold B. The upper mold B2, the lower mold B1 and the magnetic circuit assembly 2 form the basin frame molding cavity B0. Step 5: Molten plastic material is injected into the frame molding cavity B0. The plastic material solidifies to form the frame 1. The frame 1 is combined with the magnetic circuit assembly 2 to form the speaker assembly A. The frame 1 has a connecting part 11 that is glued to the magnetic circuit assembly 2. The connecting part 11 covers the outer peripheral wall of the washer 21, the magnet 22 and the T-iron 23. The connecting part 11 also covers the end face of the washer 21 and the end face of the T-iron 23. Step 6: Open the basin frame injection mold B, take out the speaker assembly A and the positioning fixture C, separate the speaker assembly A from the positioning fixture C, and repair the basin frame 1 of the speaker assembly A.

[0024] Through the above-described production method, this invention can ensure that the washer 21, magnet 22, and T-iron 23 of the magnetic circuit assembly 2 are coaxially arranged with the frame 1, which helps to improve the assembly accuracy of the entire loudspeaker.

[0025] In an embodiment of this utility model, the connecting part 11 of the basin frame 1 can form an inner ring groove 111. The inner peripheral wall of the inner ring groove 111 is attached to the outer peripheral wall of the washer 21, the magnet 22 and the T iron 23, so that the connecting part 11 covers the outer peripheral wall of the washer 21, the magnet 22 and the T iron 23 of the magnetic circuit assembly 2. The inner end faces of the two ends of the inner ring groove 111 are attached to the end face of the washer 21 and the end face of the T iron 23, respectively, so that the connecting part 11 covers the end face of the washer 21 and the end face of the T iron 23.

[0026] In an embodiment of this utility model, the positioning fixture C may include a positioning cylinder C1 and a connecting magnet C2. When the positioning fixture C is installed on the magnetic circuit assembly 2, the inner wall of the positioning cylinder C1 is against the outer wall of the T-iron 231 of the T-iron 23, and the outer wall of the positioning cylinder C1 is against the inner wall of the washer 21, thereby making the T-iron 23 and the washer 21 coaxially arranged. The connecting magnet C2 attracts the T-iron 231 of the T-iron 23, ensuring that the positioning fixture C will not fall off. In step four, after the upper mold B2 of the basin frame injection mold B is connected to the lower mold B1, the limiting post B21 of the upper mold B2 can abut against the positioning fixture C, thereby preventing the magnetic circuit assembly 2 and the positioning fixture C from shaking during injection molding.

[0027] In an embodiment of this utility model, the lower mold B1 is provided with a central positioning spring pin B11 and multiple side positioning spring pins B12. When the magnetic circuit assembly 2 with the positioning fixture C installed is inserted into the lower mold B1 of the basin frame injection mold B, the central positioning spring pin B11 of the lower mold B1 is coaxially inserted with the T-iron 23, so that the washer 21 and the T-iron are coaxially arranged with the lower mold B1. The side positioning spring pins B12 of the lower mold B1 abut against the outer peripheral wall of the magnet 22, so that the magnet 22 is coaxially arranged with the lower mold B1. In this way, the washer 21, the magnet 22 and the T-iron 23 of the magnetic circuit assembly 2 are all coaxially arranged with the lower mold B1, ensuring that the washer 21, the magnet 22 and the T-iron 23 of the magnetic circuit assembly 2 are coaxially arranged with the basin frame 1.

[0028] In the embodiments of this utility model, corresponding to each side positioning spring pin B12 of the lower mold B1, the connecting part 11 of the basin frame 1 is also provided with a plurality of through clearance openings 112 that communicate with the inner ring groove 111, and the clearance openings 112 are formed by the side positioning spring pins B12.

[0029] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
