Specifically, when the rotating mechanism 3 includes a rotating disc 31 fixedly connected to the horn 2 and a plurality of limiting shafts 32 fixedly connected to the longitudinal support 11, a plurality of threads 311 are annularly disposed on the outer circumferential surface of the rotating disc 31 at equal intervals, the screw 52 is engaged with the threads 311, the rotating disc 31 is driven to rotate by the rotation of the screw 52, so as to rotate the horn 2, the plurality of limiting shafts 32 surround the outer circumference of the rotating disc 31 and are in close contact with the rotating disc 31, which not only supports the rotating disc 31, but also enables the rotating disc 31 to rotate only in the space surrounded by the plurality of limiting shafts 32. In addition, when the rotating mechanism 3 includes the bearing 33, since the inner ring 331 of the bearing 33 is fixedly connected with the horn 2 through the sleeve 34, and the outer ring 332 of the bearing 33 is fixedly connected with the longitudinal support 11, a plurality of threads are annularly arranged on the outer circumferential surface of the sleeve 34 at equal intervals, the screw 52 is engaged with the threads, and the sleeve 34 is driven to drive the inner ring 331 of the bearing 33 to rotate through the rotation of the screw 52, so that the rotation of the horn 2 is realized. When the rotating mechanism 3 includes the gear 35 fixedly connected to the horn 2, the teeth grooves of the gear 35 are configured to be coupled with the screw 52, and the rotation of the horn 2 is achieved by rotating the screw 52 to rotate the gear 35.
In addition, the horn 2 can also be directly rotatably connected to the longitudinal support 11, that is, the driving head 22 of the horn 2 is rotatably connected to the through hole 111 of the longitudinal support 11, and the positioning grooves 36 are circumferentially arranged on the outer circumferential surface of the driving head 22 at equal intervals, and the positioning connecting members 41 detachably connected to the positioning grooves 36 are arranged on the longitudinal support 11. The positioning connecting piece 41 is installed on a fixed seat, the lower end of the positioning connecting piece 41 is in matched clamping connection with the positioning groove 36, in addition, in order to reduce the rigid contact between the positioning connecting piece 41 and the positioning groove 36, the rotation of the horn 2 is more flexible and smooth, and a reset spring is sleeved on the positioning connecting piece 41, so that the positioning connecting piece 41 can move up and down. When horn 2 needs to be rotated, horn 2 is directly pushed by hand, positioning connecting piece 41 is disconnected from positioning groove 36 under the action of external rotating force applied to horn 2, and horn 2 can be positioned by connecting positioning connecting piece 41 with one positioning groove 36 after horn 2 rotates to a required angle.
In order to make the horn more beautiful in appearance and make the sound diffusion uniform and stable, a plurality of cells 211 are arranged in the long opening 21 of the horn 2, and each cell 211 is in a tapered structure (as shown in fig. 11) which gradually shrinks from front to back. Specifically, the number of the cells 211 may be set to 4 to 12. Furthermore, the elongated opening 21 of horn 2 may also be directly formed by a plurality of cells 211 having a conical structure.
While the present invention has been described by way of examples, and not by way of limitation, other variations of the disclosed embodiments, as would be readily apparent to one of skill in the art, are intended to be within the scope of the present invention, as defined by the claims.
