A pressing column 15 is installed on the installation area 13, and the pressing column 15 passes through the alignment hole 22. Before installation, the alignment hole 22 on the thermal insulation pad 2 is aligned with the position of the pressing column 15, and the inside of the pressing column 15 is filled with rubber. After the pressing column 15 passes through the alignment hole 22, the pressing column 15 is pressed by the thumb, so that the filling rubber inside the pressing column 15 overflows, which is conducive to the thermal insulation pad 2 being adhered to the installation area 13. The thermal insulation pad 2 can also be fixed to the installation area 13 by screws. The pressing column 15 is used to facilitate operation.

[0020] Reference Figure 5 and attached Fig. 9 As shown, a circular hole 31 through which the magnetic column of the speaker body 12 passes is provided at the center of the mounting plate 3, a mounting sleeve 4 is sleeved on the outside of the magnetic column of the speaker body 12, and a plurality of gradually changing arc-shaped protrusions 41 are distributed at equal angles on the outside of the mounting sleeve 4, a limiting sleeve 5 is provided on the mounting plate 3, and a sliding groove 51 is provided on the inner ring of the limiting sleeve 5 for the gradually changing arc-shaped protrusion 41 to slide, a plurality of groups of limiting grooves 52 are provided on the outer ring of the limiting sleeve 5, and the limiting grooves 52 and the sliding grooves 51 are communicated, and a plurality of groups of extrusion grooves 53 are provided on the limiting sleeve 5; The mounting plate 3 is provided with a plurality of clamping assemblies 6 , and the gradually changing arc-shaped protrusions 41 push the clamping assemblies 6 to be fastened in the limiting grooves 52 . The top of the limiting sleeve 5 is provided with a plurality of adjustment assemblies 7 for clamping the lower part of the speaker body 12 basin frame.

[0021] The magnetic conductive column of the speaker body 12 is provided with an inserting hole 14 , and the inner circle of the mounting sleeve 4 is provided with an inserting column 42 matched with the inserting hole 14 .

[0022] The mounting sleeve 4 is an elastic band, and the gradually changing arc-shaped protrusion 41 is made of a deformable material. When in use, the inner side of the mounting sleeve 4 can be stretched open by fingers for a certain distance, and the magnetic column at the bottom of the speaker body 12 can be inserted into the mounting sleeve 4. Since the mounting sleeve 4 is an elastic band, it is beneficial for the mounting sleeve 4 to fit tightly to the outer side of the magnetic column at the bottom of the speaker body 12. At the same time, since the inner circle of the mounting sleeve 4 is designed with a plug-in column 42, the plug-in column 42 is plugged into the plug-in hole 14, so that the mounting sleeve 4 will not slide on the outer side of the magnetic column at the bottom of the speaker body 12.

[0023] For the outer clamping part of the magnetic column, please refer to the attached figure Figure 5 and attached Figure 7 As shown, the clamping assembly 6 includes a clamping plate 61 installed on the mounting plate 3, and a clamping groove 62 is provided on the clamping plate 61, and a collision body 63 that interacts with the gradual arc-shaped protrusion 41 is provided at the limiting groove 52, and a clamping block 64 is connected to one side of the collision body 63, and the front end of the clamping block 64 is a plug-in body 65 that passes through the clamping groove 62, and the lower part of the plug-in body 65 is provided with an extrusion protrusion 66 that contacts the bottom groove edge of the clamping groove 62. The clamping block 64 is connected to a connecting slider 67, a strip groove 32 is provided on the mounting plate 3, and a re-tightening spring 68 is provided inside the strip groove 32, and a section of the re-tightening spring 68 is connected to the connecting slider 67. Before the speaker body is installed, the collision body 63 is at the most side of the limiting groove 52. Because the mounting sleeve 4 is sleeved on the outside of the speaker body 12, at this time, the upper part of the speaker body is held by the palm of the hand and rotated, so that the gradually changing arc-shaped protrusion 41 on the mounting sleeve 4 gradually squeezes the collision body 63, so that the collision body 63 The clamping block 64 and the plug-in body 65 are pushed to move forward (the limiting effect of the connecting slider 67 and the strip groove 32 fixedly connected at the bottom of the clamping block 64). When the plug-in body 65 is inserted into the clamping groove 62 and the protrusion 66 is squeezed against the position of the clamping groove 62, the protrusion of the largest part of the gradual arc-shaped protrusion 41 just presses against the collision body 63. At this time, the re-tightening spring 68 is also in a compressed state, so that the gradual arc-shaped protrusion 41 drives the entire limiting sleeve 5 to fit the magnetic guide column, thereby playing a limiting role on the speaker body 12.

[0024] The mounting plate 3 is provided with a plurality of wire grooves 33, and the wire grooves 33 are distributed between two adjacent clamping plates. The bottom of the limiting sleeve 5 is also provided with a plurality of wire grooves 33. When the speaker body 12 is moved, the wires can be erected upward because the limiting sleeve 5 itself is at a certain distance from the mounting plate 3, thereby facilitating the movement of the wires. When the limiting sleeve 5 is fixedly attached to the speaker body 12, the wires are just inside the wire grooves 33, thereby protecting the wires.

[0025] For the adjustment of the outside of the basin frame, refer to the attached Figure 6 , Attachment Figure 7 and attached Fig. 9 When the locking cam 75 is in the unlocked position, the locking cam 73 is in the unlocked position, and the locking cam 73 is in the unlocked position, so that the locking cam 73 is unlocked and the locking cam 73 is unlocked.

[0026] Before installation, align the alignment hole 22 on the heat insulation pad 2 with the pressing column 15. The pressing column 15 is filled with rubber. After the pressing column 15 passes through the alignment hole 22, the pressing column 15 is pressed by the thumb to make the filling rubber inside the pressing column 15 overflow, so that the surrounding of the heat insulation pad 2 can be adhered to the installation area 13. The installation sleeve 4 is an elastic band, and the gradually changing arc-shaped protrusion 41 is made of deformable material. When in use, the inner side of the installation sleeve 4 can be stretched to a certain distance by fingers to The magnetic column at the bottom of the speaker body 12 is inserted into the installation sleeve 4. Since the installation sleeve 4 is an elastic band, it is conducive to the installation sleeve 4 to fit tightly to the outside of the magnetic column at the bottom of the speaker body 12. At the same time, since the inner circle of the installation sleeve 4 is designed with a plug-in column 42, the plug-in column 42 is plugged into the plug-in hole 14, so that the installation sleeve 4 will not slide on the outside of the magnetic column at the bottom of the speaker body 12. Before the speaker body is installed, the collision body 63 is at the side of the limit groove 52. Because the installation sleeve 4 is a sleeve When the speaker body 12 is outside, the upper part of the speaker body is held by the palm of the hand and rotated, so that the gradually changing arc-shaped protrusion 41 on the mounting sleeve 4 gradually squeezes the collision body 63, so that the collision body 63 pushes the clamping block 64 and the plug-in body 65 to move forward (the limiting effect of the connecting slider 67 and the strip groove 32 fixedly connected at the bottom of the clamping block 64). When the plug-in body 65 is inserted into the clamping groove 62 and the squeezing protrusion 66 is pressed against the position of the clamping groove 62, the largest part of the gradually changing arc-shaped protrusion 41 is The protrusion just rests against the collision body 63. At this time, the tightening spring 68 is also in a compressed state, so that the gradually changing arc-shaped protrusion 41 drives the entire limiting sleeve 5 to fit the magnetic guide column, which plays a limiting role on the speaker body 12. When the magnetic guide column of the speaker body 12 is limited and fixed, the fixing glue is introduced from the gap between the limiting sleeve 5 and the speaker body 12, so that the limiting sleeve 5, the speaker body 12 and the mounting plate form a whole, thereby avoiding the trouble of welding the speaker to the main board 11 by using a welding gun.
