[0029] An embodiment of this utility model provides an adjustable rotating shaft assembly, including a fixed base 1, a rotating shaft 2, and an adjusting component 3. The fixed base 1 is fixed to the top edge of the speaker body. A rotating groove 17 is provided on one side of the fixed base 1. The rotating shaft 2 is fixedly assembled on both sides of the rotating groove 17 of the fixed base 1. The adjusting component 3 is rotatably assembled on the fixed base 1 within the rotating groove 17 via the rotating shaft 2. The rotating shaft 2 is provided with a damping component, which is disposed on the side of the adjusting component 3 to press against the side of the adjusting component 3. The adjusting component 3 is provided with a connecting shaft 32, and the adjusting component 3 is connected to a sound column assembly 4 via the connecting shaft 32.

[0030] The adjustable rotating shaft assembly of this utility model is fixed to the top edge of the speaker body by a fixing base 1. Then, a rotating groove 17 is pre-set in the fixing base 1 for the rotation space of the adjusting component 3. The damping force generated by the damping component on the rotating shaft 2 pressing the side of the adjusting component 3, and the adjusting component 3 is connected to the sound column assembly 4 through the connecting shaft 32, so that the sound column assembly 4 can be stably fixed after rotating to any angle. The cooperation between the rotating shaft 2 and the adjusting component 3 allows the sound column assembly 4 to rotate flexibly to meet the usage requirements of different angles, and improve the flexibility of the speaker equipment and the direction of the amplifier.

[0031] In one embodiment of this utility model, the fixing base 1 is provided with a fixing member 11 and two L-shaped fixing blocks 12 fixed opposite to one side of the fixing member 11. The fixing member 11 is fixed to the top edge of the speaker body. The two L-shaped fixing blocks 12 have coaxial first fixing holes 14, and the first fixing holes 14 are provided with first fixing parts 15. In this embodiment, the fixing member 11 securely fixes the fixing base 1 to the top edge of the speaker body, and the L-shaped fixing blocks 12 are fixed opposite to each other on the same side of the fixing member 11. The two opposing L-shaped fixing blocks 12 form a symmetrical support structure, which can evenly distribute the force. The coaxial first fixing holes 14 ensure that the axis of the rotating shaft 2 is aligned during installation, reducing offset and jamming during rotation. The first fixing part 15 can accurately position and firmly connect the rotating shaft 2 and the L-shaped fixing blocks 12, preventing the rotating shaft 2 from loosening or shifting axially during use.

[0032] In one embodiment of this utility model, the rotating shaft 2 is further provided with a fixed shaft 21. A cap 24 is integrally provided at one end of the fixed shaft 21. A second fixing part 25 is provided on the shaft body of the fixed shaft 21. The fixed shaft 21 is axially fixedly engaged with the L-shaped fixing block 12 via the first fixing part 15 of the first fixing hole 14 and the second fixing part 25 of the fixed shaft 21. In this embodiment, the fixed shaft 21 is axially engaged with the first fixing part 15 of the L-shaped fixing block 12 through the second fixing part 25, allowing the fixed shaft 21 to be quickly aligned and locked in position during assembly. The cap 24 has a limiting effect at one end of the fixed shaft 21, preventing the adjusting member 3 from dislodging from the shaft body during frequent rotation.

[0033] In one embodiment of this utility model, the adjusting component 3 is further provided with an adjusting seat 31. Connecting ears 33 are provided on both sides of the adjusting seat 31 along its length. Each connecting ear 33 has a circular pivot hole 34. The adjusting seat 31 is rotatably connected to the L-shaped fixing block 12 via the pivot hole 34 of the connecting ear 33 and the fixing shaft 21. The engagement of the pivot hole 34 of the connecting ear 33 with the fixing shaft 21 provides a pivot point for the adjusting component 3, ensuring that the axis of the adjusting seat 31 remains unchanged during rotation. The rotatable connection between the adjusting seat 31 and the L-shaped fixing block 12 via the connecting ear 33 and the fixing shaft 21 allows the sound column assembly 4 to rotate flexibly around the fixing shaft 21, meeting the angle adjustment needs in different scenarios and improving usability.

[0034] In one embodiment of this utility model, the damping element is a damping washer 22, which is sleeved on the shaft of the fixed shaft 21. The rotating shaft 2 is also provided with a fixing nut 23, which is connected to the end of the fixed shaft 21 away from the cap 24 by a thread. The damping washer 22 is disposed between the fixing nut 23 and the connecting ear 33. The damping washer 22 is sleeved on the fixed shaft 21 and located between the fixing nut 23 and the connecting ear 33. The degree of compression on the damping washer 22 can be adjusted by the threaded connection of the fixing nut 23, thereby controlling the magnitude of the damping force. This ensures that the adjusting component 3 rotates smoothly and that the sound column assembly 4 remains stably stationary at any angle, preventing it from rotating on its own.

[0035] In one embodiment of this utility model, the adjusting seat 31 is further provided with a second fixing hole, and the connecting shaft 32 is provided with a limiting part 35. One end of the connecting shaft 32 near the limiting part 35 passes through the second fixing hole and is connected and locked with a nut. The second fixing hole of the adjusting seat 31 cooperates with the connecting shaft 32 to provide installation positioning for the connecting shaft 32. The limiting part 35 of the connecting shaft 32 can effectively limit the depth of the connecting shaft 32 passing through the second fixing hole. At the same time, with the locking effect of the nut, a double fixation is formed, making the connecting shaft 32 and the adjusting seat 31 firmly connected, which can withstand the weight and vibration load of the sound column assembly 4 and prevent loosening and falling off.

[0036] In one embodiment of this utility model, the fixing base 1 is further provided with a first housing 13, which covers the outside of the fixing member 11 and the L-shaped fixing block 12. Further, the adjusting member 3 is also provided with an arc-shaped second housing 36, which is connected to the adjusting base 31.

[0037] In one embodiment of this utility model, a buffer pad 16 is provided on the top of the first housing 13. When the adjusting member 3 drives the sound column assembly 4 to rotate to contact the top of the first housing 13, the buffer pad 16 can effectively buffer the impact force between the two, avoid hard contact causing wear or deformation of the housing, and protect the housing structure.

[0038] In one embodiment of this utility model, a power amplifier speaker is provided on one side of the speaker column assembly 4, and the power amplifier speaker is electrically connected to the speaker body. The rotation of the adjusting member 3 drives the speaker column assembly 4 to rotate, thereby adjusting the sound wave radiation direction of the power amplifier speaker on the speaker column assembly 4, and realizing the directional adjustment of the speaker column on the speaker.

[0039] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
