[0029] Further, refer to Figure 2 and Figure 3 It can be seen that the connecting component 3 includes a fixed frame 31, the inner wall of the speaker end cover 2 is fixedly connected to the fixed frame 31, and the inner side of the fixed frame 31 is fixedly connected to the plug-in board 32. The fixed frame 31 and the plug-in board 32 are inserted into the snap-in frame 4 through the speaker end cover 2, so that the filter box 1 and the speaker end cover 2 can be snap-connected.

[0030] Further, refer to Figure 2 and Figure 3 It can be seen that the cross section of the plug board 32 is set as a rectangular frame, and a slot adapted to the plug board 32 is opened inside the snap frame 4. The plug board 32 can be inserted into the snap frame 4 through the slot opened inside the snap frame 4.

[0031] Further, refer to Figure 3 and Figure 4 It can be seen that the locking mechanism 5 includes a guide frame 51, and the guide frame 51 is fixedly connected to the inner side of the locking frame 4, and through grooves are provided on both sides of the guide frame 51. Through the through grooves provided on both sides of the guide frame 51, the plug pin 54 can drive the connecting slider 53 to move along the through groove, playing the role of limiting and guiding the plug pin 54. The inner wall of the through groove is welded to one end of the return spring 52, and the other end of the return spring 52 is welded to the connecting slider 53. The end of the connecting slider 53 is fixedly connected to the plug pin 54, and the inner wall of the through groove is fixedly connected to the guide column 55, and the guide column 55 is set to a cylindrical shape. The interior of the connecting slider 53 is provided with a circular hole adapted to the guide column 55. By setting the guide column 55 to a cylindrical shape, the connecting slider 53 can slide along its surface and reduce wear.

[0032] Further, refer to Figure 2 and Figure 4 It can be seen that the surface of the plug pin 54 is provided with a bevel, and the inside of the clamping frame 4 and the plug board 32 are both provided with a through hole compatible with the plug pin 54. Through the bevel provided on the surface of the plug pin 54, when the bevel is squeezed by the plug board 32, the plug pin 54 can be retracted into the guide frame 51.

[0033] Further, refer to Figure 3 and Figure 4 It can be seen that the pulling mechanism 6 includes a connecting rope 61, the bottom of the connecting pin 54 is fixed to one end of the connecting rope 61, and the other end of the connecting rope 61 is wrapped around the surface of the winding disk 62, and a toggle rod 63 is fixedly connected to the top of the winding disk 62. A guide roller 64 is installed on the inner wall of the guide frame 51. The connecting rope 61 is in conflict with the surface of the guide roller 64, and the connecting rope 61 can be conveniently wound through the winding disk 62.

[0034] Further, refer to Figure 3 and Figure 4It can be seen that the limiting mechanism 7 includes a limiting frame 71, the outer end of the toggle rod 63 is installed on the limiting frame 71 through a bearing, and the outer thread of the limiting frame 71 is inserted with an extrusion screw pin 72. By rotating the extrusion screw pin 72, the extrusion screw pin 72 can be moved in the limiting frame 71. When the extrusion screw pin 72 is squeezed with the surface of the toggle rod 63, the toggle rod 63 can be limited.

[0035] Working principle: When the filter box 1 is in use, the utility model Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 , the fixing frame 31 and the plug plate 32 are driven to be inserted into the card frame 4 through the speaker end cover 2, so that the plug plate 32 can squeeze the inclined surface of the plug pin 54. When the inclined surface of the plug pin 54 is squeezed, the plug pin 54 can drive the connecting slider 53 to move along the guide frame 51, so that the plug pin 54 can be retracted into the guide frame 51, and the return spring 52 is compressed. When the plug plate 32 conflicts with the inner wall of the card frame 4, the elastic force of the return spring 52 itself can push the connecting slider 53 and the plug pin 54 to reset. At this time, the plug pin 54 is inserted into the plug plate 32 and the card frame 4, which facilitates the card connection between the filter box 1 and the speaker end cover 2, and the sealing ring 8 can increase the sealing between the filter box 1 and the speaker end cover 2. When the horn end cover 2 needs to be disassembled, the extrusion screw pin 72 is rotated to make the extrusion screw pin 72 move away from the surface of the toggle lever 63. At this time, the toggle lever 63 is rotated to drive the reel 62 to rotate, so that the reel 62 can reel in the connecting rope 61, and the connecting rope 61 can pull the plug pin 54 downward through the guidance of the guide roller 64. When the plug pin 54 is removed from the plug plate 32 and the clamping frame 4, the extrusion screw pin 72 is rotated to make the extrusion screw pin 72 conflict with the surface of the toggle lever 63. At this time, the toggle lever 63 is limited, and multiple groups of toggle levers 63 are rotated in turn. When multiple groups of plug pins 54 are removed from the plug plate 32 and the clamping frame 4, the filter box 1 and the horn end cover 2 can be disassembled.
