[0007] Furthermore, the driving assembly includes a second motor fixed to the inner bottom wall of the shell, a driving gear fixed to the end of the output shaft of the second motor, and a driven gear fixedly sleeved on the vertical rod and meshing with the driving gear.

[0008] By adopting the above technical solution, when the speaker body needs to be rotated, the user starts the second motor to drive the driving gear to rotate. Since the driving gear is meshed with the driven gear, and the driven gear is fixedly mounted on the vertical rod, the vertical rod drives the mounting plate to rotate, thereby rotating the adjustment assembly and the speaker body, thereby facilitating the adjustment of the angle of the speaker body.

[0009] Furthermore, a controller is disposed on the upper surface of the shell, and the controller is electrically connected to the first motor and the second motor.

The mounting plate 4 is a circular plate-shaped structure, and the mounting plate 4 is fixed to the upper end of the vertical rod 3, and the axis of the mounting plate 4 coincides with the axis of the vertical rod 3.

[0032] The adjustment component 5 is installed on the mounting plate 4 and is used to adjust the angle of the speaker body 2. The adjustment component 5 includes a fixing plate 51, a first motor 52, a rotating shaft 53 and a fixing seat 54. The fixing plate 51 is a plate-like structure, and the fixing plate 51 is fixed to the upper surface of the mounting plate 4. The first motor 52 is fixed to the side wall of the fixing plate 51, and the output shaft of the first motor 52 passes through the side wall of the fixing plate 51 and is rotatably connected. The rotating shaft 53 is a horizontally arranged round rod-shaped structure, and the rotating shaft 53 is fixed to the end of the output shaft of the first motor 52, and the axis of the rotating shaft 53 coincides with the axis of the output shaft of the first motor 52. The fixing seat 54 is fixedly sleeved on the rotating shaft 53, and the fixing seat 54 is fixed to the bottom of the speaker body 2.

[0033] The driving assembly 6 is installed in the housing 1, and is used to drive the vertical rod 3 to rotate. The driving assembly 6 includes a second motor 61, a driving gear 62 and a driven gear 63. The second motor 61 is fixed on the inner bottom wall of the housing 1, and the output shaft of the second motor 61 extends vertically upward. The driving gear 62 is fixed to the end of the output shaft of the second motor 61, and the axis of the driving gear 62 coincides with the axis of the output shaft of the second motor 61. The driven gear 63 is fixedly sleeved on the vertical rod 3, and the driven gear 63 is meshed with the driving gear 62, and the axis of the driven gear 63 coincides with the axis of the vertical rod 3. The controller 7 is arranged on the upper surface of the housing 1, and the controller 7 is electrically connected to the first motor 52 and the second motor 61.

[0034] When the angle of the speaker body 2 needs to be adjusted, the user starts the first motor 52 through the controller 7 to drive the rotating shaft 53 to rotate, driving the fixing seat 54 and the speaker body 2 to rotate along the axis of the rotating shaft 53, thereby adjusting the angle of the speaker body 2, and then starts the second motor 61 through the controller 7 to drive the driving gear 62 to rotate. Since the driving gear 62 is meshed with the driven gear 63, and the driven gear 63 is fixedly mounted on the vertical rod 3, the vertical rod 3 drives the mounting plate 4 to rotate, thereby rotating the speaker body 2 for adjustment, which is convenient for adjusting the angle of the speaker body 2 and the sound concentration direction, and is conducive to meeting the auditory needs of passengers in different positions.

[0035] In order to enhance the rotation stability of the mounting plate 4, an annular support plate 8 is provided on the inner bottom wall of the shell 1, and an annular groove 81 is provided on the upper surface of the annular support plate 8.
