Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a multi-segment loudspeaker U-shaped magnetic structure. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals, and its performance greatly affects sound quality. The loudspeaker is the weakest component in an audio system, yet it is also one of the most crucial parts for sound quality. The U-shaped iron in a loudspeaker is the core metal component in the magnetic circuit system. Named for its resemblance to the letter "U," its main function is to construct the magnetic circuit framework and guide the direction of magnetic lines of force, making it one of the key structures ensuring the loudspeaker's electroacoustic conversion efficiency.

[0003] Most existing speaker U-shaped irons are integrated structures. When an integrated U-shaped iron is damaged, the entire structure needs to be replaced. Furthermore, integrated U-shaped irons have poor heat dissipation performance. Utility Model Content

[0020] This utility model provides a technical solution:

[0021] Please see Figures 1-6 The diagram shows a multi-segment loudspeaker U-shaped magnetic structure, including a base 1, which is an annular structure. A mounting post 2 is installed on the top outer wall of the base 1, and a top post 3 is installed on the top outer wall of the mounting post 2. A strip groove is opened on the bottom outer wall of the mounting post 2, and a connecting component 6 is installed on the inner wall of the strip groove. An annular groove 4 is opened on the top outer wall of the base 1, and two symmetrically arranged positioning grooves 5 are opened on the inner wall of the annular groove 4. The connecting component 6 is snapped into the two positioning grooves 5, and a ridge groove 11 is opened on one side of the inner wall of each of the two positioning grooves 5. Two symmetrically arranged locking slots 12 are opened on the bottom outer wall of the base 1, and the locking slots 12 are located directly below the positioning grooves 5.

[0022] In this embodiment, the multi-segment U-shaped iron is formed by combining a base 1, a mounting post 2, and a top post 3. The connecting component 6 at the bottom of the mounting post 2 facilitates fixing the mounting post 2 to the base 1. The two positioning slots 5 on the base 1 facilitate the installation and positioning of the mounting post 2, thereby improving the installation efficiency of the mounting post 2. The ridge groove 11 and the slot 12 assist in the fixed installation of the mounting post 2.

[0023] Please see Figures 5-6The connecting assembly 6 shown in the figure includes a connecting box 14 fixedly connected to the inner wall of the strip groove. Two symmetrically arranged drive seats 18 are slidably connected to the inner wall of the connecting box 14. Both outer walls of the connecting box 14 have slits, and prisms 16 are slidably connected to the inner walls of both slits. The two prisms 16 are respectively fixedly connected to the two drive seats 18. The bottom outer wall of the connecting box 14 has two symmetrically arranged rectangular openings, and L-shaped plates 15 are slidably connected to the inner walls of both rectangular openings. The two L-shaped plates 15 are respectively fixedly connected to the two drive seats 18. The specifications of the L-shaped plates 15 are the same as those of the slots 12. With matching specifications, the inner wall of the connecting box 14 is fixedly connected to two symmetrically arranged connecting plates, and each connecting plate has a screw 17 rotatably connected to one side of its outer wall. Two drive seats 18 are respectively screwed onto the outer walls of the two screws 17. The same worm gear 19 is rotatably connected to the opposite side of the outer wall of the two connecting plates. The drive shaft of the worm gear 19 is fixedly connected to the two screws 17. The inner wall of the connecting box 14 is rotatably connected to a worm 20, and the worm 20 and the worm gear 19 mesh with each other. The bottom outer wall of the connecting box 14 is rotatably connected to a rotating part 13, and one end of the drive shaft of the rotating part 13 is fixedly connected to the worm 20.

[0024] In this embodiment, when the mounting post 2 is installed on the base 1, the connecting box 14 is first inserted into the two positioning slots 5, and then the rotating part 13 is rotated to drive the worm 20 to rotate. When the worm 20 rotates, it drives the two screws 17 to rotate synchronously through the worm wheel 19. When the two screws 17 rotate synchronously, they drive the two drive seats 18 to move towards or away from each other. When the two drive seats 18 move away from each other, they push the prism 16 to insert into the prism groove 11, and at the same time, the L-shaped plate 15 is engaged in the slot 12, so as to facilitate fixing the mounting post 2 on the base 1. The cross section of the rotating part 13 is a regular hexagon.

The bottom outer wall of the top column 3 is fixedly connected to a connecting column 8, and the top outer wall of the top column 3 is rotatably connected to a locking bolt 9 that passes through the top column 3 and the connecting column 8. The locking bolt 9 is screwed into the inner wall of the screw hole 10. The cross-sections of the connecting column 8 and the connecting groove 7 are both regular hexagonal structures.

[0026] In this embodiment, when installing the top post 3, the connecting post 8 is first inserted into the connecting groove 7, and then the locking bolt 9 is rotated. When the locking bolt 9 is screwed into the screw hole 10, the top post 3 is directly fixed on the mounting post 2.
