DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , a music playing device, including a mounting rack 1, a music player 2 and a fixed electric rod 3. A placement groove communicating left and right is provided at the front end of the mounting rack 1. A positioning post 4 is provided on the bottom wall of the placement groove. A positioning groove 5 matching the positioning post 4 is provided at the bottom end of the music player 2. The positioning post 4 is rotatably connected within the positioning groove 5. A circular groove is provided at the top end of the music player 2, and an annular internal gear 6 is installed within the circular groove. An upper opening communicating with the placement groove is provided at the top end of the mounting rack 1. A rotating bearing 7 is fixedly installed in the middle of the fixed electric rod 3, and the rotating bearing 7 is installed within the upper opening. The bottom output end of the fixed electric rod 3 is fixedly connected with an adjusting gear 8, and the adjusting gear 8 meshes with the annular internal gear 6. At the same time, when repairing or disassembling the music player 2, by closing the fixed electric rod 3, it drives the adjusting gear 8 to disengage from the annular internal gear 6, so that the music player 2 can be taken out from the placement groove. Therefore, the music player 2 can be installed or disassembled conveniently and quickly, which facilitates maintenance and replacement and improves convenience; a stepping driving mechanism is provided on the outer side of the fixed electric rod 3. Through the setting of the stepping driving mechanism, the fixed electric rod 3 is driven and adjusted. The adjusting gear 8 connected to the bottom end of the fixed electric rod 3 rotates within the annular internal gear 6, thereby adjusting the position of the music player 2. Therefore, the practicability is improved, and the playing effect in different directions is improved.

[0021] The stepping driving mechanism includes a stepping motor 9 and a driven wheel 10. The stepping motor 9 is installed on the top end of the mounting rack 1 through a frame. The bottom output end of the stepping motor 9 extends into the placement groove and is fixedly connected with a driving wheel 11. The driven wheel 10 is sleeved on the lower half area of the fixed electric rod 3, and the driving wheel 11 meshes with the driven wheel 10. The fixed electric rod 3 is driven to rotate through the cooperation of the stepping motor 9, the driving wheel 11 and the driven wheel 10, so as to adjust its direction.

[0022] Arc-shaped sliding grooves 12 are provided on both the left and right sides of the bottom wall of the placement groove, and lower sliding blocks 13 matching the arc-shaped sliding grooves 12 are installed on both the left and right sides of the bottom end of the music player 2, which limits the position of the music player 2 and can move along the direction of the arc-shaped sliding grooves 12.

[0023] It further includes two groups of T-shaped plates 14. Arc-shaped card slots 15 are provided on the left and right sides of the top wall of the placement groove. The two groups of T-shaped plates 14 are respectively slidably clamped with the two groups of arc-shaped card slots 15. Connecting components are threadedly connected to the bottoms of the two groups of T-shaped plates 14. Fixing screw grooves are provided on the left and right sides of the top end of the music player 2. The two groups of connecting components are respectively connected to the two fixing screw grooves. The two arc-shaped card slots 15 and the two arc-shaped sliding grooves 12 are vertically opposite. Through the arrangement of the two groups of T-shaped plates 14 and the two groups of connecting components, the position of the music player 2 is limited, and its stability is improved.

[0024] Each of the two groups of connecting components includes a connecting rod 16. An upper thread groove 17 threadedly connected to the T-shaped plate 14 is provided at the top end of the connecting rod 16. Threads are provided on the outer side of the vertical section of the T-shaped plate 14 from top to bottom. An external thread 18 matching the fixing screw groove is provided on the outer bottom wall of the connecting rod 16. When the connecting rod 16 is threadedly connected upward from the outside of the T-shaped plate 14 to the maximum area, the connecting rod 16 moves out of the fixing screw groove. When the connecting rod 16 is threadedly connected downward from the outside of the T-shaped plate 14 to the minimum area, the external thread 18 is completely matched with the fixing screw groove. Through the arrangement of the connecting rod 16, the T-shaped plate 14 is connected and fixed to the music player 2, and at the same time, it is ensured that when the music player 2 is disassembled, the two connecting rods 16 can be separated from the music player 2.

[0025] The maximum distance from the positioning column 4 to the adjusting gear 8 is greater than the height of the music player 2. The minimum distance from the positioning column 4 to the adjusting gear 8 is the distance between the positioning groove 5 and the annular internal gear 6. The positioning groove 5 and the circular groove are respectively located at the central area of the bottom end and the central position of the top end of the music player 2, avoiding the music player 2 from tilting and shaking.

[0026] During use, when installing the music playback device, the mounting bracket 1 is fixed on the wall surface. The positioning posts 4 on the bottom wall of the placement groove are inserted into the positioning grooves 5 at the bottom end of the music player 2, thereby fixing the music player 2. Then, the fixed electric rod 3 is turned on. The adjusting gear 8 connected to the bottom end of the fixed electric rod moves into the annular internal gear 6 in the circular groove, causing the adjusting gear 8 to mesh with the annular internal gear 6. When adjusting the speaker orientation of the music player 2, the direction is adjusted through the stepper drive mechanism, that is, the stepper motor 9 is turned on. The stepper motor 9 drives the driven wheel 10 to rotate through the drive wheel 11. The driven wheel 10 is sleeved on the outer side of the fixed electric rod 3. Therefore, the fixed electric rod 3 rotates accordingly. The adjusting gear 8 connected to the bottom end of the fixed electric rod 3 rotates within the annular internal gear 6, thereby adjusting the orientation position of the music player 2. As a result, the practicality is improved, the playback effect when used in different directions is enhanced, and it is ensured that the sound played by the music player 2 has the maximum effect on the listener. At the same time, when repairing or disassembling the music player 2, by turning off the fixed electric rod 3, it drives the adjusting gear 8 to disengage from the annular internal gear 6. Then, the connecting rod 16 is turned, causing the connecting rod 16 to screw out of the fixed screw groove. At the same time, the connecting rod 16 screws upward on the outer side of the T-shaped plate 14, separating the two connecting rods 16 from the music player 2. Then, the music player 2 is taken out of the placement groove. Therefore, the music player 2 can be installed or disassembled conveniently and quickly, facilitating maintenance and replacement, and improving the convenience.
