Detailed implementation manners

[0019] The following further describes the present application in detail with reference to the Figures 1-4 accompanying drawings.

[0020] An embodiment of the present application discloses a lift type ceiling speaker.

[0021] Referring to Figure 1 and Figure 2 and Figure 3 the lift type ceiling speaker includes a mounting member 1, a housing main body 2, a lifting main body 3, a speaker main body 4, and a driving mechanism 5. The mounting member 1 is disposed on the housing main body 2, and the housing main body 2 is vertically and fixedly installed in the ceiling board through the mounting member 1, so that the lower edge of the housing main body 2 is flush with the outer surface of the ceiling board, thereby recessing the housing main body 2 in the ceiling. The interior of the housing main body 2 is hollow and its lower end is open. The lifting main body 3 is located in the inner cavity of the housing main body 2. The lifting main body 3 is hollow and its lower end is open. The speaker main body 4 is fixedly installed at the lower end of the inner cavity of the lifting main body 3. The lower edge of the lifting main body 3 is curled outward along its circumference and is provided with a first light strip 31. The inner edge of the lower end of the speaker main body 4 is provided with a second light strip 32 along its circumference.

[0022] Referring to Figure 2 and

[0023] and Figure 2 and Figure 3, a horizontal fixing frame 21 is fixedly installed on the inner wall of the housing main body 2 by screws. The driving mechanism 5 is arranged on the fixing frame 21 and connected to the lifting main body 3. When the audio is needed to be used, the driving mechanism 5 drives the lifting main body 3 to move downward, so that the lower end of the lifting main body 3 can extend out of the opening at the lower end of the housing main body 2, that is, the lower end of the lifting main body 3 extends out of the suspended ceiling board.

[0024] Refer to Figure 3 and Figure 4 , the driving mechanism 5 includes a straight cylinder 51, a threaded rod 52 and a power assembly 53. The inside of the straight cylinder 51 is hollow and the lower end is open. The lower end of the straight cylinder 51 is fixedly connected to the upper surface at the center of the fixing frame 21 by screws. The threaded rod 52 is vertically welded in the inner cavity of the straight cylinder 51. A vertical connecting column 54 is integrally formed at the upper end of the lifting main body 3. The connecting column 54 passes through the fixing frame 21 and extends into the straight cylinder 51. The connecting column 54 is threadedly sleeved on the threaded rod 52.

[0025] Refer to Figure 3 and Figure 4 , the power assembly 53 includes a motor 531, a gear set 532 and a driving gear 533. The driving gear 533 is rotatably connected to the upper surface of the fixing frame 21, and the driving gear 533 is coaxially sleeved outside the connecting column 54. A plurality of limiting strips 55 are integrally formed on the outer wall of the connecting column 54 along its axial direction. The plurality of limiting strips 55 are evenly arranged and distributed along the circumferential direction of the connecting column 54. Then, a plurality of limiting grooves 56 for accommodating the limiting strips 55 are correspondingly formed in the inner ring of the driving gear 533. The limiting strips 55 are slidably connected in the limiting grooves 56. The motor 531 is fixedly connected to the fixing frame 21 by screws. The motor 531 is a servo motor. In this embodiment, the gear set 532 includes a driving gear and a driven gear. The driving gear and the driven gear mesh with each other and are both rotatably connected to the upper surface of the fixing frame 21. The output shaft of the motor 531 faces downward and is coaxially fixed to the driving gear of the gear set 532. The driven gear of the gear set 532 meshes with the driving gear 533. In other embodiments, the gear set 532 can also be a single gear or more than two gears, and the number of gears is set according to the actual situation.

[0026] Refer to Figure 1, a plurality of through grooves 11 are circumferentially formed in the outer wall of the outer shell main body 2 near the lower end. A plurality of mounting members 1 are provided, and one mounting member 1 is arranged in each through groove 11. Among them, the mounting member 1 includes a fixing rod 12, a spring 13, and a mounting block 14. The fixing rod 12 is vertically arranged and threadedly penetrates through the through groove 11. The spring 13 is sleeved on the fixing rod 12. The mounting block 14 is slidably sleeved on the fixing rod 12. The spring 13 is located below the mounting block 14, so that the lower end of the mounting block 14 abuts against the upper end of the spring 13. Before installing the outer shell main body 2 on the integrated ceiling, a hole for placing the outer shell body is formed at the reserved position of the ceiling board in advance, and then the outer shell main body 2 is placed. At this time, the mounting block 14 is located inside the ceiling board. Since the mounting block 14 is sleeved on the fixing rod 12, the mounting block 14 is toggled to make one end of the mounting block 14 extend out of the through groove 11. Then, the mounting block 14 is fixed to the ceiling board by using screws, so as to complete the recessed installation of the outer shell main body 2 and the ceiling.

[0027] Referring to Figure 3 With Figure 4 , in order to better control the lifting position of the lifting main body 3, a positioning member one 7 and a positioning member two 8 are fixedly embedded on the outer wall of the lifting main body 3. In this embodiment, both the positioning member one 7 and the positioning member two 8 are strong magnetic circular sheet magnets, and the positioning member one 7 is located directly above the positioning member two 8. A position sensing element 9 for sensing the positions of the positioning member one 7 and the positioning member two 8 is installed on the side wall of the outer shell main body 2. The position sensing element 9 is located on the vertical movement track of the positioning member one 7 and the positioning member two 8. The position sensing element 9 is a magnetic sensor; a controller is provided. The controller can be a PLC controller. The audio control system, the motor 531, and the position sensing element 9 are respectively electrically connected to the controller.

[0028] Embodiment:

[0029] When the audio is in the off state (not in use), the upper edge of the connecting column 54 abuts against the inner wall of the upper end of the straight cylinder 51. At this time, the lower edge of the lifting body 3 is flush with the lower edge of the housing body 2. At the same time, the sensing part of the position sensing element 9 is aligned with the positioning member two 8. When the audio needs to be used, the motor 531 drives the gear 533 group 532 to rotate, driving the driving gear 533 to rotate. The driving gear 533 drives the connecting column 54 to rotate. Since the connecting column 54 is threadedly connected to the threaded rod 52, under the limiting action of the limiting strip 55, the connecting column 54 can move downward, thereby driving the lower end of the lifting body 3 to gradually extend out of the lower end opening of the housing body 2. When it descends to the position where the positioning member one 7 is aligned with the sensing part of the position sensing element 9, the position sensing element 9 feeds back a position signal to the controller, and then the motor 531 is controlled to stop rotating. At this time, the lifting body 3 descends to the lowest position; when the audio is turned off, the motor 531 is controlled to rotate in the reverse direction, and the connecting column 54 drives the lifting body 3 to move upward. When it rises to the position where the positioning member two 8 is aligned with the sensing part of the position sensing element 9, the position sensing element 9 feeds back a position signal to the controller, and then the motor 531 is controlled to stop rotating. At this time, the lifting body 3 completes the reset.

[0030] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
