[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-6 This embodiment provides a freely rotating screen structure, including a screen body 10, for information display and visual interactive operation; The connecting mechanism 20 allows the screen body 10 to rotate freely on the speaker device. The connecting mechanism 20 includes a pivot bracket 21 with up-and-down flip shafts 22 at both ends. A horizontal rotation shaft 23 is provided in the middle of the pivot bracket 21, and a fixed bracket 24 connected to the screen body 10 is provided on the horizontal rotation shaft 23.

[0018] In this embodiment, at least two connecting holes are provided at the end of the vertical flip shaft 22 away from the rotating shaft bracket 21. After the screw passes through the connecting holes, the vertical flip shaft 22 can be fixed to the speaker device. After the vertical flip shaft 22 is fixed to the speaker device, the rotating shaft bracket 21 can rotate around the two vertical flip shafts 22 as the axis. The fixed bracket 24 is also provided with bolt holes. The fixed bracket is fixed to the screen body 10 by screws or bolts. Therefore, the screen body 10 can flip up and down with the vertical flip shaft 22 as the axis of rotation. Since the fixed bracket 24 and the rotating shaft bracket 21 are connected by the horizontal rotating shaft 23, the screen body 10 can rotate horizontally by the relative rotation between the fixed bracket 24 and the horizontal rotating shaft 23. With the cooperation of the vertical flip shaft 22 and the horizontal rotating shaft 23, the screen body 10 can flip back and forth and rotate left and right, and freely adjust its orientation without requiring the user to accommodate the device, which is more user-friendly.

[0019] To ensure electrical connection between the screen body 10 and the speaker device, a horizontal rotation axis 23 passes through the rotation bracket 21 and is hollow, allowing the screen body 10's cables to pass through and connect to the speaker device. This connection ensures that the screen body 10's free angle adjustment via the vertical flip axis 22 and the horizontal rotation axis 23 does not affect signal transmission between the screen body 10 and the speaker. Furthermore, the cables of the screen body 10 will not interfere with angle adjustment during multi-angle rotation.

[0020] To ensure that the cable will not break when the screen body 10 is adjusted at multiple angles, a limit piece 233 is provided on the horizontal rotation axis 23. The end of the limit piece 233 has a protruding locking position, and the fixed bracket 24 is provided with a locking block 241 that cooperates with the limit piece 233 to prevent the cable from breaking. The limiting piece 233 with a protruding locking position is fixed to the outer sleeve of the horizontal rotating shaft 23 by screws. This ensures that the inner sleeve of the horizontal rotating shaft 23 does not move when the screen body 10 rotates. When the screen body 10 rotates horizontally, the fixing bracket 24 rotates accordingly. When the locking block 241 at the bottom of the fixing bracket 24 moves to the protruding locking position, the locking structure holds the locking block 241 in place. At this time, the horizontal rotating shaft 23 can no longer rotate, so that the rotation angle of the screen body 10 through the horizontal rotating shaft 23 is less than 360 degrees. This ensures that the screen body 10 will not rotate excessively during horizontal rotation and break the cable, ensuring the safety of the screen body 10 angle adjustment, avoiding unrestricted rotation that could cause the internal wires to break, and extending the product life.

[0021] Specifically, the vertically rotating shaft 22 is detachably mounted on the end of the rotating shaft bracket 21 via a first nut 221 and a first washer 222, and the fixed bracket 24 is detachably mounted on the horizontal rotating shaft 23 via a second nut 231 and a second washer 232. This detachable design facilitates precise alignment of components during production and assembly, and allows for individual disassembly and replacement of corresponding components in case of wear or loosening of the rotating shaft, eliminating the need for overall disassembly and reducing maintenance costs.

[0022] It should be noted that the connecting mechanism 20 also includes a protective shell 25 located outside the pivot bracket 21. The protective shell 25 is composed of a front cover and a rear cover that cooperate with each other. The protective shell 25, composed of the front cover and the rear cover, can protect the rotation axis of the rotating structure of the screen body 10, achieving the effect of waterproofing and dustproofing.

[0023] A karaoke speaker has a freely rotating screen structure as described above. The karaoke speaker design simplifies the overall structure, integrating a complex karaoke speaker system into a single unit. This results in simple packaging, minimal space occupation, easy portability and use, reduced costs, and more flexible and diverse application scenarios.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
