Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-4 A rotatable and adjustable speaker includes a mounting shell 1 and a speaker 6 disposed inside the mounting shell 1. The mounting shell 1 is provided with a pitch adjustment mechanism 2. The mounting shell 1 is provided with a fixing frame 3 through the pitch adjustment mechanism 2. The bottom of the fixing frame 3 is provided with a fixing box 4. The fixing box 4 is provided with a left and right rotation mechanism 5. The fixing frame 3 is connected to the speaker 6 through the left and right rotation mechanism 5.

[0022] The pitch adjustment mechanism 2 includes a motor 7, a transmission rod 8, a gear 9, a main shaft 10, a main connecting block 11, and a gear 12. The motor 7 is fixedly mounted on the inner wall of the mounting housing 1. The transmission rod 8 is fixedly mounted on the output end of the motor 7. The gear 9 is fixedly mounted on the transmission rod 8. The main shaft 10 is rotatably mounted inside the mounting housing 1. The main connecting block 11 is fixedly mounted on the middle of the fixing frame 3. The gear 12 is fixedly mounted on the main shaft 10. It is used to control the speaker 6 to achieve the function of tilting up or tilting down.

[0023] The left and right rotation mechanism 5 includes a second motor 16, a worm gear 17, a worm wheel 18, and a rotating shaft 19. The second motor 16 is fixedly installed in the fixed box 4, the worm gear 17 is rotatably installed in the fixed box 4, the worm wheel 18 is rotatably installed in the fixed box 4, and the rotating shaft 19 is fixedly installed on the speaker 6 to control the speaker 6 to rotate in the left and right directions.

[0024] It should be noted that speaker 6, motor 1 7, and motor 2 16 are existing technologies, all of which support remote control or smart device connection. The specific model and specifications to be used need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts existing technology in this field, so it will not be elaborated here. All of them can be powered by external devices and controlled to turn on and off.

[0025] Furthermore, a pair of stabilizers 13 are provided on the main shaft 10. A connecting rod 14 is fixedly provided on the opposite side of the stabilizers 13. A secondary connecting block 15 is provided on the fixed frame 3. The connecting rod 14 and the secondary connecting block 15 are rotatably connected. Both the fixed frame 3 and the stabilizers 13 are U-shaped. Neither the fixed frame 3 nor the stabilizers 13 affect the left and right rotation of the speaker 6. The U-shaped fixed frame 3 and the stabilizers 13 ensure the stability of the speaker 6 during rotation and avoid the interference of the mechanical structure on the sound propagation.

[0026] Furthermore, the worm gear 18 is fixedly connected to the rotating shaft 19 located at the bottom of the speaker 6. The rotating shaft 19 is rotatably connected to the fixed frame 3. The left and right rotating mechanism 5 enables the speaker to rotate horizontally, adapting to different spatial layouts and usage scenarios. Whether in a home theater, conference room, or exhibition hall, users can adjust the left and right angles of the speaker as needed to ensure a wider and more uniform sound coverage.

[0027] Working principle:

[0028] When the pitch angle of the speaker 6 needs to be adjusted, motor 7 starts, driving transmission rod 8 to rotate, and gear 9 on transmission rod 8 rotates accordingly. Gear 9 meshes with gear 12 fixed on main shaft 10, thereby driving main shaft 10 to rotate. Main shaft 10 is connected to fixed frame 3 through main connecting block 11, and fixed frame 3 drives speaker 6 to tilt up or down. At the same time, the stabilizing frame 13 on main shaft 10 is rotatably connected to secondary connecting block 15 on fixed frame 3 through connecting rod 14, ensuring the stability of speaker 6 during pitch adjustment and avoiding the impact of mechanical vibration on sound quality.

[0029] When the left and right angle of speaker 6 needs to be adjusted, motor 16 starts, driving worm gear 17 to rotate. Worm gear 17 meshes with worm wheel 18, driving worm wheel 18 to rotate. Worm wheel 18 is connected to rotating shaft 19 fixed to the bottom of speaker 6, thereby driving speaker 6 to rotate horizontally around rotating shaft 19. Rotating shaft 19 is rotatably connected to fixed frame 3, ensuring that speaker 6 remains stable during left and right rotation.

[0030] Through the coordinated operation of the pitch adjustment mechanism 2 and the left-right rotation mechanism 5, users can remotely control the up-down and left-right angles of the speaker 6 according to actual needs, flexibly adjusting the sound field direction. Whether in a home theater, conference room, or exhibition hall, the speaker 6 can achieve precise angle adjustment via motor drive, ensuring a wider and more uniform sound coverage to meet the needs of different scenarios.

[0031] 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.
