[0002] The loudspeaker is an indispensable electroacoustic conversion device in modern electronic devices. Its core function is to convert electrical signals from the power amplifier into sound waves that can be heard by the human ear. During the production and processing of loudspeakers, it is necessary to glue the loudspeaker components together.

[0003] A search revealed that Chinese Patent Publication No. CN222551276U discloses a positioning fixture for speaker processing. The fixture includes a positioning mechanism, which facilitates the placement of the speaker body through a positioning groove, limits the position of the speaker body, and facilitates subsequent processing operations by the user. A front baffle limits the position of the speaker body to prevent it from falling out of the positioning groove without affecting subsequent processing operations by the user.

[0004] In actual use, the positioning device must ensure that the centers of the magnetic column and the magnet are concentric during the installation process. However, during the installation process, workers often cause deviations between the magnetic column and the magnet, resulting in noise mixed in the sound emitted by the speaker. To solve this problem, a positioning fixture for speaker processing is proposed. Utility Model Content

A limiting groove is formed on the upper surface of the movable sleeve. A connecting block is fixedly connected to the side of the movable sleeve.

[0008] As a further description of the above technical solution:

[0009] The pressing component has an arc-shaped surface on its side, and the center of the pressing component corresponds to the center of the mounting component. The threaded block is L-shaped, and the size of the threaded block is adapted to the size of the embedded groove.

This allows the piston plate to squeeze the spring, and at the same time, the pressing block will come into contact with the trigger component, thereby causing the electromagnet to lose its magnetism and release the limiting of the connecting block. This allows the spring force to push the movable sleeve to move, so that the spring can regain its elasticity. This can prevent the spring from being in a compressed state for a long time, which would affect its use.

After the fixing rod is fully inserted into the fixing groove, the vertical end of the threaded block is engaged with the horizontal part of the clamp, so that the threaded block can be stably limited in the embedded groove.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-3 One embodiment of this utility model provides a positioning fixture for speaker processing, including a mounting base 1. The bottom of the mounting base 1 has a mounting groove 2. A motor 3 is fixedly connected to the top of the inner wall of the mounting groove 2. A rotating shaft 4 is fixedly connected to the output end of the motor 3. A rotating disk 5 is fixedly connected to the top of the rotating shaft 4. A positioning post 6 is fixedly connected to the top of the rotating disk 5. The positioning post 6 can effectively limit the magnetic column. A limiting component 7 is provided inside the rotating disk 5. The limiting component 7 can limit the magnet.

[0036] Reference Figure 3 , Figure 5 and Figure 6The limiting component 7 includes a bidirectional threaded rod 702, a mounting part 703, and a pressing part 705. A movable groove 701 is opened inside the rotating disk 5. The bidirectional threaded rod 702 is rotatably connected inside the movable groove 701. The mounting part 703 is threadedly connected to the outer surface of the bidirectional threaded rod 702. This allows the two mounting parts 703 to approach the guide magnetic column or the outer surface of the magnet when the bidirectional threaded rod 702 rotates. A small threaded rod 704 is rotatably connected to the bottom of the inner wall of the mounting part 703. A threaded block 718 is threadedly connected to the outer surface of the small threaded rod 704. The threaded block 718 is L-shaped and its size is adapted to the size of the embedding groove 719. This allows the pressing part 705 to be stably limited after the threaded block 718 is inserted into the embedding groove 719.

[0037] The pressing member 705 is disposed on the outer surface of the threaded block 718. The pressing member 705 has an arc-shaped surface on its side. The center of the pressing member 705 corresponds to the center of the mounting member 703. An embedding groove 719 is formed on the side of the pressing member 705. A fixing member 706 is fixedly connected to the side of the pressing member 705. A limiting block 712 is fixedly connected to the top of the fixing member 706. The position of the limiting block 712 corresponds to the position of the limiting groove 714. The limiting block 712 is disposed inside the limiting groove 714, allowing the limiting block 712 to be positioned within the limiting groove 714. The groove 714 moves inside, and the moving length of the movable sleeve 713 is limited, preventing the movable sleeve 713 from detaching from the fixing member 706. A trigger member 717 is fixedly connected to the top of the inner wall of the fixing member 706, and an electromagnet 716 is fixedly connected to the top of the fixing member 706. The electromagnet 716 and the trigger member 717 are electrically connected. When the pressing block 710 is retracted into the fixing member 706, it will come into contact with the trigger member 717, thereby causing the electromagnet 716 to lose its magnetism, thus releasing the limiting of the connecting block 715.

[0038] The piston inside the fixed component 706 is connected to a piston plate 707, and a rubber piston ring is fixedly connected to the outer side of the piston plate 707, which makes the piston plate 707 more stable during movement. A spring 711 is fixedly connected to the side of the piston plate 707, and the spring 711 is sleeved on the outer surface of the piston rod 708. At the same time, the end of the spring 711 contacts the inner wall of the movable sleeve 713. A piston rod 708 is fixedly connected to the side of the piston plate 707, and the center of the piston rod 708 corresponds to the center of the piston plate 707. The end of the piston rod 708 is set through the piston plate 707. A limit plate 709 is fixedly connected to the left end of the piston rod 708, and the right end of the piston rod 708 is fixedly connected to the limit plate 709. A pressing block 710 is fixedly connected. The side of the pressing block 710 is arc-shaped and has a rubber layer. The size of the pressing block 710 is adapted to the internal size of the fixing member 706. This ensures that the pressing block 710 will not damage the magnetic column or magnet after contacting the outer surface of the magnetic column or magnet. A movable sleeve 713 is sleeved on the outer surface of the fixing member 706. A limiting groove 714 is formed on the upper surface of the movable sleeve 713. A connecting block 715 is fixedly connected to the side of the movable sleeve 713. The position of the connecting block 715 corresponds to the position of the electromagnet 716. The attraction force generated by the electromagnet 716 on the connecting block 715 limits the movable sleeve 713.

[0039] Reference Figure 4 and Figure 7 An auxiliary component 8 is provided on the side of the pressing member 705 near the fixing member 706. The auxiliary component 8 includes a fixing groove 801, which is located on the side of the pressing member 705 near the fixing member 706. The center of the fixing groove 801 corresponds to the center of the vertical part of the threaded block 718 and the center of the fixing groove 801 corresponds to the center of the locking member 803. A fixing rod 802 is locked inside the fixing groove 801, which allows the fixing rod 802 to be stably locked into the fixing groove 801. The end of the fixing rod 802 is fixedly connected to the locking member 803. The locking member 803 is L-shaped and has a slot on the side of the horizontal part of the locking member 803. The inner wall of the slot is provided with anti-slip texture, which increases the friction between the locking member 803 and the outer surface of the vertical part of the threaded block 718 and allows the threaded block 718 to be better limited inside the embedding groove 719.

[0040] Working principle: The magnetic column is placed on the upper surface of the rotating disk 5, allowing the positioning pin 6 to engage inside the magnetic column, thus stably positioning it. Simultaneously, the small threaded rod 704 is rotated to align the pressing member 705 with the magnetic column. Then, the bidirectional threaded rod 702 is rotated to bring the mounting member 703 closer to the magnetic column, simultaneously bringing the outer surface of the pressing block 710 into contact with the outer surface of the magnetic column. This allows the piston rod 708 to move within the fixing member 706, and the piston plate 707 to move within the fixing member 706, pressing the spring 711. Simultaneously, after the pressing block 710 contacts the trigger member 717, the electromagnet 716 loses its magnetism, releasing the limiting position of the connecting block 715. This allows the spring 711's elasticity to push the movable sleeve 713, restoring the spring's elasticity and demonstrating to the operator that the magnetic column or magnet is stably positioned. This helps maintain the magnetic column and magnet in a more effective concentric state.

[0041] Furthermore, when replacing or installing a damaged pressing component 705, the L-shaped threaded block 718 is inserted into the embedding groove 719, which limits the pressing component 705. Then, the fixing rod 802 is inserted into the fixing groove 801. After the fixing rod 802 is fully inserted into the fixing groove 801, the groove on the horizontal side of the L-shaped clamping component 803 is inserted into the vertical end of the threaded block 718. The inner wall of the groove is provided with anti-slip texture, which increases the friction between the clamping component 803 and the outer surface of the vertical part of the threaded block 718, and allows the threaded block 718 to be better limited in the embedding groove 719.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
