[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] This embodiment includes a ceiling-mounted speaker, such as... Figures 1 to 5 As shown, the device includes a ceiling box 1 for installation at a specific location and a speaker assembly 3 for sound generation. To ensure a more stable installation of the ceiling box 1 at the specific location, a mounting bracket 10 is provided inside the ceiling box 1, and the two ends of the mounting bracket 10 are fixed to the inner walls on both sides of the ceiling box 1 by bolts.

[0024] The ceiling box 1 and the speaker assembly 3 are connected by a connecting rod 2. Specifically, the top of the connecting rod 2 is rotatably connected to the ceiling box 1, while the bottom of the connecting rod 2 is hinged to the speaker assembly 3. This design allows the top of the connecting rod 2 to rotate circumferentially around the ceiling box 1, thereby causing the speaker assembly 3 at its bottom to rotate. At the same time, because the speaker assembly 3 is hinged to the bottom of the connecting rod 2, the speaker assembly 3 can swing around the connecting rod 2, allowing the user to adjust the angle of the speaker assembly 3 according to actual usage.

[0025] Furthermore, a locking device is provided at the end of the connecting rod 2 that is rotatably connected to the ceiling box 1. The locking device can lock the connecting rod 2 after it rotates to a specified angle to prevent the connecting rod 2 from rotating unexpectedly. The locking device includes a hollow screw 11 located at the bottom of the ceiling box 1 and a nut 13 threadedly connected to the screw 11. An expansion portion 12 extending axially is provided at the bottom of the screw 11, and the top of the connecting rod 2 is inserted into the expansion portion 12. When it is necessary to lock the connecting rod 2, it is only necessary to rotate the nut 13 to move it downward. At this time, the inner end face of the nut 13 will cause the expansion portion 12 at the bottom of the screw 11 to deform and gradually contract, thereby causing the inner wall of the expansion portion 12 to grip the connecting rod 2 and achieve a locking connection.

[0026] It should be noted that the expansion part 12 is an elastic flap, and there are at least two elastic flaps. An axially penetrating gap is provided between each elastic flap, so that the expansion part 12 can contract radially inward when squeezed by the nut 13. In addition, the outer wall of the elastic flap is provided with a thread that matches the pattern on the screw 11. This thread is adapted to the internal thread of the nut 13. Furthermore, the inner wall of the elastic flap is also machined with anti-slip texture or provided with a rubber pad to enhance the friction between the inner wall of the elastic flap and the surface of the connecting rod 2, ensuring a locking effect.

[0027] Furthermore, the speaker assembly 3 includes a cylindrical body 30 and a speaker body 31 fixedly disposed within the cylindrical body 30. The bottom of the connecting rod 2 is hinged to the cylindrical body 30, and the connecting rod 2 has a hollow tubular structure. The hollow part inside the connecting rod 2 is connected to the inside of the cylindrical body 30. With this design, the audio wire can start from inside the ceiling box 1, be laid along the inner wall of the hollow tubular structure of the connecting rod 2, pass through the connection point between the two, and extend directly into the inside of the cylindrical body 30 to complete the electrical connection with the speaker body 31. In this way, the wire is completely wrapped inside the structure, effectively avoiding the aesthetic problems and safety hazards caused by exposed wires.

[0028] Furthermore, a buffer block 33 is fixedly installed inside the cylinder 30. The speaker body 31 is fixedly installed inside the cylinder 30 through the buffer block 33. By installing the buffer block 33, when the speaker body 31 vibrates during operation, the buffer block 33 can absorb most of the vibration energy generated by the speaker body 31, greatly suppressing the shaking of the cylinder 30, thereby avoiding the problem of the cylinder 30 angular displacement caused by the shaking of the cylinder 30.

[0029] In addition, the buffer block 33 is provided with multiple through slots 331. These through slots 331 are arranged along the height direction of the buffer block 33 and are evenly distributed around the circumference of the buffer block 33. By providing the through slots 331, when the audio wire enters the cylinder 30, the audio wire can be connected to the speaker body 31 at the bottom of the buffer block 33 through the through slots 331 on the buffer block 33. When multiple audio wires pass through, the through slots 331 can also classify and organize audio wires of different functions, preventing the audio wires from getting tangled together inside the cylinder 30, which is beneficial for subsequent maintenance work.

[0030] In addition, a cover plate 34 is provided on the top of the cylinder 30 and is detachably connected to the cylinder 30. The cover plate 34 is provided with a plurality of heat dissipation holes 341 for heat dissipation. When the speaker body 31 generates heat during operation, the heat can flow through the through groove 331 on the buffer block 33 to the top of the cylinder 30 and be quickly dissipated to the external environment through the heat dissipation holes 341 on the cover plate 34.

[0031] Furthermore, a protective device 32 is also provided inside the cylinder 30. The protective device 32 is located below the speaker body 31. The protective device 32 includes a support ring 321, which is snapped into the cylinder 30. Specifically, hooks 322 extend from the support ring 321, and multiple hooks 322 are distributed circumferentially along the support ring 321. An annular groove 301 is provided inside the cylinder 30 to engage with the hooks 322. The protective device 32 also includes a dustproof net 323, which overlaps the top of the support ring 321. By setting the dustproof net 323 on the top of the support ring 321, dust, debris, and other particles can be effectively blocked from entering the interior of the cylinder 30, preventing them from adhering to the surface of the speaker body 31 and avoiding the impact of dust accumulation on the acoustic performance of the speaker body 31 or causing short circuits and other malfunctions.
