One end of the adjusting screw 15 is threadedly connected with the sliding block 12, and by rotating the adjusting screw 15, the support plate 4 can be driven to rotate, so as to realize the adjustment and positioning of the tilting degree of the support plate 4, and at the same time, the sliding block 12 slides in the let-go sliding groove 11, so as to avoid the jamming of the adjusting screw 15 in the adjusting process.

[0037] In order to realize the height and horizontal angle adjustment of the sound body 5, the embodiment further comprises a lifting and rotating assembly. The lifting and rotating assembly comprises a rotating sleeve 17 rotatably installed on the top of the base 1, and a threaded rod 18 slidably connected with the inside of the rotating sleeve 17 through a convex strip. The top end of the threaded rod 18 is fixedly provided with a mounting plate 19, and the mounting plate 19 is fixedly connected with the bottom of the lifting plate 3. The rotating sleeve 17 is located in the inside of the mounting bracket 2, and the outer wall of the rotating sleeve 17 is fixedly provided with a worm gear 20. A worm 21 is rotatably installed between the two side inner walls of the mounting bracket 2, and the worm 21 is engaged with the worm gear 20. A first motor 22 is fixedly installed on one side of the mounting bracket 2, and one end of the output shaft of the first motor 22 is rotatably connected with one end of the worm 21. By starting the first motor 22, the worm 21 can be driven to rotate, and then the worm gear 20 and the rotating sleeve 17 are driven to rotate, so as to realize the horizontal angle adjustment of the sound body 5.
