[0028] Example:

[0029] The present application embodiment discloses a high frequency loudspeaker structure. Figure 1 , Figure 2 and Figure 3 , comprising a box body 1, a circuit board 10 arranged inside the box body 1 and a door body 3 arranged on the surface of the box body 1, a mounting hole 11 is opened on the left end surface of the box body 1, a connecting pipe is arranged inside the mounting hole 11, the left end of the connecting pipe is fixedly connected to the speaker body 2, the outer side of the connecting pipe is fixedly connected to the fixing plate 5, a slot 16 and a slot 2 9 are symmetrically opened on the left end surface of the box body 1, an insert block 14 and an insert block 2 12 are symmetrically fixedly connected on the inner surface of the fixing plate 5, a limiting groove 15 and a limiting groove 2 13 are respectively opened on the top of the insert block 14 and the insert block 2 12, and a limiting component 8 is arranged on the upper side of the left end surface of the box body 1.

[0030] See also Figure 2 The limiting assembly 8 includes a groove 81 opened on the left end surface of the box body 1, and a moving plate 82 is slidably connected inside the groove 81. The bottom end surface of the moving plate 82 is symmetrically fixedly connected with two plug rods 1 83 and two plug rods 2 84. A spring 85 is arranged between the plug rod 1 83 and the plug rod 2 84. The inner bottom wall of the groove 81 is symmetrically provided with two connecting holes 1 and two connecting holes 2, which drive the moving plate 82 to move upward. The moving plate 82 moves upward to stretch the spring 85, and the moving plate 82 moves upward to drive the plug rod 1 83 and the plug rod 2 84 to move upward, so that the lower end of the plug rod 1 83 moves out from the inside of the limiting groove 15, and the lower end of the plug rod 2 84 moves out from the inside of the limiting groove 2 13, thereby releasing the limiting fixation of the plug block 14 and the plug block 2 12, so that the plug block 14 and the plug block 2 12 can be removed from the inside of the slot 1 16 and the slot 2 9 respectively, which facilitates the disassembly of the fixed plate 5 and the speaker body 2.

[0031] See also Figure 2 and Figure 3 One end of the spring 85 is fixedly connected to the bottom end surface of the movable plate 82, and the other end of the spring 85 is fixedly connected to the inner bottom wall of the groove 81. The bottom end of the connecting hole 1 is connected to the slot 16, and the bottom end of the connecting hole 2 is connected to the slot 2 9. The bottom end of the insert rod 1 83 passes through the connecting hole 1 and extends to the inside of the limiting groove 15, thereby limiting and fixing the insert block 14. The bottom end of the insert rod 2 84 passes through the connecting hole 2 and extends to the inside of the limiting groove 2 13, thereby limiting and fixing the insert block 2 12.

[0032] See also Figure 1The inner wall of the groove 81 is symmetrically provided with sliding grooves, the inner bottom wall of the sliding groove and the bottom end surface of the moving plate 82 are in the same horizontal plane, and both ends of the moving plate 82 are fixedly connected with sliding blocks adapted to the sliding grooves, and the height of the sliding block is equal to the thickness of the moving plate 82. The cooperation between the sliding block and the sliding groove limits the moving plate 82. When the moving plate 82 moves, the moving plate 82 drives the sliding block to move inside the sliding groove, thereby improving the stability of the moving plate 82 when moving.

A limiting circular groove is provided on the top of the fixing plate 5, and the lower end of the fixing bolt 7 is inserted in the inside of the limiting circular groove. The fixing plate 5 is placed between the supporting plate 4 and the limiting plate 6, and then the fixing bolt 7 is screwed so that the lower end of the fixing bolt 7 is inserted in the inside of the limiting circular groove. The fixing plate 5 is further fixed by the support plate 4, and the double fixing effect of the speaker body 2 is achieved by cooperating with the limiting component 8, so that the installation is firm and reliable.

[0034] The implementation principle of the embodiment of the present application is as follows: tighten the fixing bolt 7 so that the fixing bolt 7 moves out from the inside of the limiting circular groove, thereby releasing the limiting fixation of the fixing plate 5, and then driving the movable plate 82 to move upward. The movable plate 82 moves upward to stretch the spring 85, and the movable plate 82 moves upward to drive the insertion rod 1 83 and the insertion rod 2 84 to move upward, so that the lower end of the insertion rod 1 83 moves out from the inside of the limiting groove 15, and the lower end of the insertion rod 2 84 moves out from the inside of the limiting groove 2 13, thereby releasing the limiting fixation of the insertion block 14 and the insertion block 2 12, so that the insertion block 14 and the insertion block 2 12 can be removed from the inside of the slot 1 16 and the slot 2 9 respectively, which facilitates the disassembly of the fixing plate 5 and the speaker body 2.
