[0033] Please see Figures 1-7A universal bracket for mounting a speaker includes a mounting frame 1. The mounting frame 1 has a movable device, which includes a fixed plate 2, a connecting plate 3, a second screw 4, a second screw sleeve 5, and a rotating bracket 6. The fixed plate 2 is detachably mounted on one side of the connecting plate 3. The second screw sleeve 5 is mounted on one side of the connecting plate 3. The second screw 4 and the second screw sleeve 5 are movably connected by threads. The rotating bracket 6 is located on one side of the connecting plate 3. A fixing device is mounted on one side of the connecting plate 3. The fixing device includes a fixed sleeve 7, a control sleeve 8, a flexible band 9, a mating sleeve 10, a connecting block 11, and a fixing rod 12. The control sleeve 8 is rotatably connected to the outside of the fixed sleeve 7. One end of the mating sleeve 10 is connected to the fixed sleeve 7 via the flexible band 9. The inner wall of the fixed sleeve 7 is connected, and the outer wall of the mating sleeve 10 is movably connected to the inner wall of the control sleeve 8 through threads. The connecting block 11 is fixedly mounted on the flexible belt 9. The fixed sleeve 7 and the mating sleeve 10 are sleeved on the outside of the fixed rod 12. The fixed rod 12 is fixedly connected to both sides of the fixed plate 2. A reinforcing mechanism is provided on the outside of the fixed sleeve 7. The reinforcing mechanism includes a pressure sleeve 13, a sliding groove 14, a receiving groove 15, a push spring 16, and a movable block 17. The inner wall of the pressure sleeve 13 is movably connected to the outer wall of the control sleeve 8 through threads. The sliding groove 14 passes through the side wall of the fixed sleeve 7. The connecting block 11 slides through the sliding groove 14. The movable block 17 is connected to the inner wall of the receiving groove 15 through the push spring 16. The receiving groove 15 is opened in the connecting block 11.

[0034] A fixing block 18 is connected to one side of the connecting block 11, and a fixing groove 19 is opened on the outer side of the fixing rod 12. One side of the fixing block 18 is in contact with the inner wall of the fixing groove 19.

[0035] A limiting groove 20 is provided on the inner side of the fixed sleeve 7, and a limiting block 21 is fixed on the outer side of the sleeve 10. The limiting block 21 is slidably disposed in the limiting groove 20.

[0036] The outer thread of the fitting sleeve 10 is set clockwise, and the inner thread of the pressure sleeve 13 is set counterclockwise.

[0037] A guide rail 22 is fixedly provided on the outer side of the fixed sleeve 7, and a guide groove 23 is provided on the inner side of the pressure sleeve 13. The guide groove 23 is adapted to the guide rail 22.

[0038] One side of the active block 17 features a chamfered design.

[0039] In this embodiment, when the speaker needs to be installed, the control sleeve 8 is first rotated clockwise. Because the inner wall thread of the pressure sleeve 13 is designed to rotate counter-clockwise, and the guide rail 22 and guide groove 23 limit the pressure sleeve 13, the pressure sleeve 13 will not rotate. Then, the pressure sleeve 13 will slide along the guide rail 22 and guide groove 23 towards the control sleeve 8. Then, the inner wall of the pressure sleeve 13 no longer limits the outer side of the movable block 17. Then, the push spring 16 in the receiving groove 15 resets, and the push spring 16 pushes the movable block 17 to reset, causing the movable block 17 to extend out of the fixed sleeve 7. Simultaneously, because the outer wall thread of the mating sleeve 10 is designed to rotate clockwise, and the limiting block 21 and limiting groove 20 cooperate to limit the mating sleeve 10, the mating sleeve 10 cannot rotate. Then, the engaging sleeve 10 will cause the limiting block 21 to slide along the limiting groove 20 towards the side closer to the operating sleeve 8. Then, one end of the engaging sleeve 10 will cooperate with the inner wall of the fixing sleeve 7 to squeeze the flexible band 9, so that the flexible band 9 is no longer taut. This will cause the connecting block 11 to no longer press the fixing block 18 against the inner wall of the fixing groove 19, and the engaging sleeve 10 to no longer press the connecting plate 3. Then, the fixing sleeve 7 is pulled outward, and the inner wall of the fixing groove 19 squeezes one side of the fixing block 18, causing the fixing block 18 to tilt the connecting block 11. This will cause the flexible band 9 to deform, thereby removing the fixing sleeve 7 and the engaging sleeve 10 from the outside of the fixing rod 12. Then, the other corresponding fixing sleeves 7 are removed, and then the connecting plate 3, which is not connected to the second screw sleeve 5 on one side, is removed. Remove the connector plate 3, then insert the speaker between the two fixing plates 2. Next, reinstall the removed connector plate 3 onto one side of the fixing plate 2, ensuring that the fixing rod 12 on one side of the fixing plate 2 passes through the pre-drilled mounting hole on the connector plate 3. Then, re-fit the fixing sleeve 7 onto the outside of the fixing rod 12, so that one end of the fixing rod 12 contacts the inner wall of the fixing sleeve 7. At this point, the mating sleeve 10 does not press the connector plate 3 tightly. Then, rotate the control sleeve 8 counterclockwise. Due to the clockwise threaded connection between the outer wall of the mating sleeve 10 and the inner wall of the control sleeve 8, and the guiding and limiting functions of the limiting block 21 and the limiting groove 20, one side of the mating sleeve 10 will drive the limiting block 21 to slide along the limiting groove 20, and one side of the mating sleeve 10 will gradually press the connector plate 3 tightly against the fixing plate 2. Simultaneously, the sleeve 10 will cause the flexible belt 9 to tighten, thereby causing the fixing block 18 to gradually press against the side wall of the fixing groove 19. The flexible belt 9 will also cause the connecting block 11, the movable block 17, and the fixing block 18 to slide along the slide groove 14. After the sleeve 10 presses the connecting plate 3, the flexible belt 9 tightens and causes the fixing block 18 to completely clamp the fixing rod 12 through the fixing groove 19. At the same time, due to the counterclockwise threaded connection between the inner wall of the pressure sleeve 13 and the outer wall of the control sleeve 8, and the limiting and guiding function of the guide rail 22 and the guide groove 23, the pressure sleeve 13 will slide along the guide rail 22 and the guide groove 23 in a direction away from the control sleeve 8. Due to the chamfered design on the outer side of the movable block 17, the pressure sleeve 13 will gradually press the movable block 17.The movable block 17 gradually presses against the push spring 16 connected to one side, causing the push spring 16 to gradually retract into the receiving groove 15. When the pressure sleeve 13 completely presses the movable block 17 inward, the push spring 16 is fully compressed. This, combined with the pressure of the pressure sleeve 13 on one side of the movable block 17 and the abutment of the fixing groove 19 and the fixing rod 12, creates a double-sided limiting mechanism, preventing the fixing block 18 from tilting or moving, thus establishing a stable fixing relationship.

[0040] Please see Figure 1 and Figure 3 As a further implementation of the overall equipment: a support frame 24 is fixedly provided above the mounting frame 1, a first screw 25 is provided on one side of the support frame 24, and a first screw sleeve 26 is fixedly provided on one side of the rotating frame 6. The first screw 25 and the first screw sleeve 26 are movably connected by threads.

[0041] Both the first screw 25 and the second screw 4 have a control panel 27 connected to one end.

[0042] More specifically, when installing the speaker, first install the speaker inside the connecting plate 3 and the fixing plate 2, then install the mounting bracket 1 in the corresponding position. When adjusting the first angle, rotate the first screw 25 using the control panel 27, so that the first screw 25 and the first threaded sleeve 26 no longer clamp the support bracket 24. Then, directly rotate the rotating bracket 6, causing the rotating bracket 6 to drive the connecting plate 3 and the fixing plate 2 to rotate at an angle, thereby causing the speaker to adjust at a certain angle. After the adjustment is appropriate, keep the rotating bracket 6 stationary. After it is settled, reverse the first screw 25 using the control panel 27, so that the first screw 25 gradually screws into the first threaded sleeve 26, thereby causing the first screw 25 and the first threaded sleeve 26 to clamp the support bracket 24 again, preventing the rotating bracket 6 from shifting. When the second installation angle needs to be adjusted, rotate the second screw 4 clockwise using another control panel 27. This causes the second screw 4 to gradually unscrew from the second sleeve 5, and the second screw 4 and the second sleeve 5 no longer clamp the rotating frame 6. Then rotate the connecting plate 3 and the fixing plate 2 to adjust the speaker's second angle. Once the angle is adjusted appropriately, rotate the second screw 4 counterclockwise using the control panel 27, keeping the second sleeve 5 stationary. Then, the second screw 4 gradually screws into the second sleeve 5, and the second screw 4 and the second sleeve 5 clamp the rotating frame 6 together, thus preventing the connecting plate 3, the fixing plate 2, and the speaker from changing their angles. When the speaker's installation angle needs to be changed again, follow the steps described above.

[0043] In summary, during the use or operation of the overall equipment: When the speaker needs to be installed, first rotate the control sleeve 8 clockwise. Due to the counter-clockwise design of the inner wall thread of the pressure sleeve 13, and the limiting effect of the guide rail 22 and guide groove 23 on the pressure sleeve 13, the pressure sleeve 13 will not rotate. Then, the pressure sleeve 13 will slide along the guide rail 22 and guide groove 23 towards the control sleeve 8. Then, the inner wall of the pressure sleeve 13 will no longer limit the outer side of the movable block 17. Then, the push spring 16 set in the receiving groove 15 will reset. Then, the push spring 16 will push the movable block 17 to reset, and make the movable block 17 extend to the outside of the fixed sleeve 7. At the same time, due to the clockwise design of the outer wall thread of the mating sleeve 10, and the limiting block 21 and limiting groove 20 forming a limiting effect on the mating sleeve 10, the mating sleeve 10 will be able to move. Sleeve 10 cannot rotate. Then, sleeve 10 will cause the limiting block 21 to slide along the limiting groove 20 towards the side closer to the operating sleeve 8. One end of sleeve 10 will then engage with the inner wall of the fixing sleeve 7 to compress the flexible band 9, causing the flexible band 9 to loosen. This prevents the connecting block 11 from pressing the fixing block 18 against the inner wall of the fixing groove 19, and the sleeve 10 from pressing the connecting plate 3. The fixing sleeve 7 is then pulled outwards, and the inner wall of the fixing groove 19 compresses one side of the fixing block 18, causing the fixing block 18 to tilt the connecting block 11. This causes the flexible band 9 to deform, thus removing the fixing sleeve 7 and sleeve 10 from the outside of the fixing rod 12. Then, the other corresponding fixing sleeves 7 are removed, and the side without the second threaded sleeve 5 is then... Remove the connecting plate 3, then insert the speaker between the two fixing plates 2. Next, reinstall the removed connecting plate 3 onto one side of the fixing plate 2, ensuring that the fixing rod 12 on one side of the fixing plate 2 passes through the pre-drilled mounting hole on the connecting plate 3. Then, re-fit the fixing sleeve 7 onto the outside of the fixing rod 12, so that one end of the fixing rod 12 contacts the inner wall of the fixing sleeve 7. At this point, the mating sleeve 10 does not press the connecting plate 3 tightly. Then, rotate the control sleeve 8 counterclockwise. Due to the clockwise threaded connection between the outer wall of the mating sleeve 10 and the inner wall of the control sleeve 8, and the guiding and limiting functions of the limiting block 21 and the limiting groove 20, one side of the mating sleeve 10 will drive the limiting block 21 to slide along the limiting groove 20, and one side of the mating sleeve 10 will gradually press the connecting plate 3 tightly against the fixing plate. On one side, the engaging sleeve 10 simultaneously tightens the flexible band 9, causing the fixing block 18 to gradually press against the side wall of the fixing groove 19. The flexible band 9 also causes the connecting block 11, the movable block 17, and the fixing block 18 to slide along the slide groove 14. When the engaging sleeve 10 presses the connecting plate 3, the flexible band 9 tightens, causing the fixing block 18 to completely clamp the fixing rod 12 through the fixing groove 19. Simultaneously, due to the counter-clockwise threaded connection between the inner wall of the pressure sleeve 13 and the outer wall of the control sleeve 8, and the limiting and guiding functions of the guide rail 22 and guide groove 23, the pressure sleeve 13 slides away from the control sleeve 8 along the guide rail 22 and guide groove 23. Due to the chamfered design on the outer side of the movable block 17, the pressure sleeve 13 gradually presses against the movable block 17.The movable block 17 gradually presses against the push spring 16 connected to one side, causing the push spring 16 to gradually retract into the receiving groove 15. When the pressure sleeve 13 completely presses the movable block 17 inward, the push spring 16 is fully compressed. This, combined with the pressure of the pressure sleeve 13 on one side of the movable block 17 and the abutment of the fixing groove 19 and the fixing rod 12, creates a double-sided limiting mechanism, preventing the fixing block 18 from tilting or moving, thus establishing a stable fixing relationship.

[0044] When installing the speaker, first install the speaker inside the connecting plate 3 and the fixing plate 2, then install the mounting bracket 1 in the corresponding position. When adjusting the first angle, rotate the first screw 25 using the control panel 27, so that the first screw 25 and the first threaded sleeve 26 no longer clamp the support bracket 24. Then, directly rotate the rotating bracket 6, causing the connecting plate 3 and the fixing plate 2 to rotate at an angle, thereby adjusting the speaker angle. After the adjustment is appropriate, keep the rotating bracket 6 stationary. After it is settled, reverse the first screw 25 using the control panel 27, so that the first screw 25 gradually screws into the first threaded sleeve 26, thereby causing the first screw 25 and the first threaded sleeve 26 to clamp the support bracket 24 again, preventing the rotating bracket 6 from rotating. When the second installation angle needs to be adjusted, rotate the second screw 4 clockwise using another control panel 27, causing the second screw 4 to gradually unscrew from the second sleeve 5. This disengages the second screw 4 and the second sleeve 5 from clamping the rotating frame 6. Then, rotate the connecting plate 3 and the fixing plate 2 to adjust the speaker's second angle. Once the angle is adjusted appropriately, rotate the second screw 4 counterclockwise using the control panel 27, keeping the second sleeve 5 stationary. Then, gradually screw the second screw 4 into the second sleeve 5, causing the second screw 4 and the second sleeve 5 to clamp the rotating frame 6, thus preventing changes in the angle of the connecting plate 3, the fixing plate 2, and the speaker. When the speaker's installation angle needs to be changed again, follow the steps described above.

[0045] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
