[0015] Compared with the prior art, this utility model provides a wide-frequency suspended speaker, which has the following beneficial effects:

[0016] 1. This wide-frequency suspended speaker adjusts the height of the speaker body by controlling a stepper motor to rotate a lead screw, which in turn moves a threaded sleeve up and down, and simultaneously moves a connecting block up and down. The connecting block then moves the mounting bracket synchronously, causing the speaker body to move up and down along two vertical plates. This solves the problem that existing wide-frequency suspended speakers require adjusting the installation height during use, making them unsuitable for different installation needs and causing inconvenience.

[0017] 2. During the installation of this wide-frequency suspended speaker, the installation angle of the speaker body can be adjusted by aligning the positioning parts with the positioning holes at different positions on the mounting plate. The angle can be fixed by the screws on the positioning parts cooperating with the corresponding positioning holes below them, thus improving the flexibility of installation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 This embodiment of a wide-frequency suspended speaker includes a top plate 1, a hanging plate 2 disposed below the top plate 1, and a mounting bracket 3 disposed below the hanging plate 2. The speaker body 4 is mounted on the inner side of the mounting bracket 3 by screws. The top plate 1 has multiple mounting holes. A lifting mechanism is provided between the mounting bracket 3 and the hanging plate 2. The lifting mechanism includes a mounting box 5 fixedly mounted on the bottom of the hanging plate 2. A stepper motor 6 is fixedly mounted inside the mounting box 5. A lead screw 7 is fixedly mounted on the output shaft of the stepper motor 6. The lower end of the lead screw 7 is connected to the inner wall of the mounting box 5 by a bearing. A threaded sleeve 8 is threadedly connected to the outer side of the lead screw 7. A connecting block 9 extending to the outside of the mounting box 5 is fixedly connected to the outer side of the threaded sleeve 8. The connecting block 9 is fixedly connected to the outer side of the mounting bracket 3.

[0025] The mounting box 5 has a slotted opening, through which a connecting block 9 passes for movement. A mounting plate 10 is bolted to the top of the mounting plate 2. A vertical plate 11 extending to the lower side of the mounting plate 2 is integrally formed at the bottom of the mounting plate 10. A connecting plate 12 is fixedly connected to the lower side of the vertical plate 11. There are two mounting plates 10 and two vertical plates 11, symmetrically distributed on both sides of the speaker body 4. A connecting plate 12 is fixedly connected to the lower side of each vertical plate 11. A sliding groove 13 is provided on the outer wall of the speaker body 4. A slider 14, which slides along the sliding groove 13, is provided on the connecting plate 12. When the speaker body 4 moves up and down, it can move stably up and down along the outer side of the slider 14 via the sliding groove 13, thus providing guidance.

[0026] In this embodiment, a connecting assembly is provided between the mounting plate 2 and the top plate 1. The connecting assembly includes a fixed shaft 15 fixedly connected to the bottom of the top plate 1, and a mounting plate 16 fixedly connected to the bottom of the fixed shaft 15. Multiple positioning elements 17 are evenly distributed around the periphery of the mounting plate 16. The positioning elements 17 are fixedly connected to the top of the mounting plate 2, and are connected to the mounting plate 16 by screws.

During installation, the mounting angle of the speaker body 4 can be easily adjusted by engaging the positioning elements 17 with the positioning holes at different positions on the mounting plate 16.

[0027] The working principle of the above embodiments is as follows:

[0028] In use, the stepper motor 6 drives the lead screw 7 to rotate, which in turn drives the threaded sleeve 8 to move up and down. At the same time, the connecting block 9 moves up and down, which in turn drives the mounting bracket 3 to move synchronously, and drives the speaker body 4 to move up and down along the two vertical plates 11, thereby adjusting the height of the speaker body 4.

[0029] During the suspension installation of the speaker body 4, the installation angle of the speaker body 4 can be adjusted by aligning the positioning part 17 with the positioning holes at different positions on the mounting plate 16. The angle can be fixed by the screws on the positioning part 17 engaging with the corresponding positioning holes below them.
