[0002] The main function of a loudspeaker is to amplify sound. It can convert electrical signals into sound signals and amplify them to a level that is audible. This allows us to hear a wide variety of sounds, from music to speech to ambient sounds. Another important function of a loudspeaker is to transmit sound. It can transmit sound over long distances, allowing us to hear sounds in different environments. Therefore, loudspeakers are widely used in public and commercial spaces.

[0003] During the manufacturing process of loudspeakers, the housing needs to be processed. When processing a square loudspeaker housing, it is necessary to fix the loudspeaker housing. However, traditional fixing devices can generally only fix the two sides of the loudspeaker housing, but cannot fix the top of the loudspeaker housing. This results in low applicability of traditional fixing devices and reduces work efficiency. Utility Model Content

[0004] To address the problems raised in the background art, this utility model researches and designs a speaker housing fixing device, which can fix the speaker housing on both sides, top and bottom, and allows the speaker housing to rotate without manually unscrewing the housing. This solves the problem that traditional fixing devices cannot fix the top of the speaker housing, resulting in low applicability of traditional fixing devices.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example

[0021] like Figures 1-4 As shown, a speaker housing fixing device includes a housing 1, a housing 2 below the housing 1, a first moving groove 3 on the top of the housing 1, a first fixing mechanism 4 inside the housing 1, and a second fixing mechanism 5 above the first fixing mechanism 4. The first moving groove 3 works in conjunction with the first fixing mechanism 4. The first fixing mechanism 4 is used to clamp and fix the speaker housing on both sides, and the second fixing mechanism 5 works in conjunction with the housing 1 to fix the top and bottom of the speaker housing.

[0022] In this implementation, such as Figure 1 As shown, the first fixing mechanism 4 and the second fixing mechanism 5 are fixed from different directions, which can adapt to speaker housings of different sizes and shapes, thus improving the versatility of the device.

[0023] In this embodiment, as Figure 1 , Figure 2 As shown, the first moving groove 3 provides a path for the movement of the first fixing mechanism 4. The first fixing mechanism 4 is responsible for clamping and fixing the speaker housing from both sides. The second fixing mechanism 5 cooperates with the housing 1 to fix the speaker housing from the top and bottom. The speaker housing is fixed by the coordinated fixing of both sides and the vertical direction.

[0024] In this embodiment, as Figure 1 , Figure 2As shown, the first fixing mechanism 4 includes a motor 401 fixedly connected to the inner wall of the housing 1. A bevel gear 402 is fixedly connected to the output end of the motor 401. The bevel gear 402 meshes with a bevel gear 403. A bidirectional lead screw 404 is fixedly connected to the inner wall of the bevel gear 403. Both ends of the bidirectional lead screw 404 extend to the outer side of the bevel gear 403 and are rotatably connected to the inner wall of the housing 1 via bearings. A transmission plate 405 is connected to the surface of the bidirectional lead screw 404. The top of the transmission plate 405 extends to the top of the housing 1 via a first moving groove 3. The surface of the transmission plate 405 is open. A second movable slot 6 is provided. When the motor 401 is started, the output end of the motor 401 drives the bevel gear 402 to rotate. The bevel gear 402 meshes with the second bevel gear 403, thereby driving the bidirectional lead screw 404 to rotate. When the bidirectional lead screw 404 rotates, the transmission plate 405 on its surface will move relative to or towards each other along the axis of the bidirectional lead screw 404, thereby realizing the clamping or releasing action on both sides of the speaker housing, reducing the tediousness of manual operation. The design of the bidirectional lead screw 404 ensures the symmetry of the movement of the two transmission plates 405, making the clamping force more uniform and avoiding damage to the housing due to uneven force.

[0025] In this embodiment, as Figures 1-3 As shown, the second fixing mechanism 5 includes a screw 501 rotatably connected to the inner wall of the second movable groove 6 via bearings. A pressure block 502 is drivenly connected to the surface of the screw 501. The front and rear sides of the pressure block 502 are slidably connected to the inner wall of the second movable groove 6. The top of the screw 501 extends to the top of the transmission plate 405 and is fixedly connected to a handwheel 503. The surface of the screw 501 is rotatably connected to the inner wall of the transmission plate 405 via bearings, which allows the height of the pressure block 502 to be flexibly adjusted according to the size of the speaker housing. The second movable groove 6 ensures the stability of the movement of the pressure block 502 and prevents the pressure block 502 from shifting during the pressing process. After the first fixing mechanism 4 completes the clamping on both sides, the handwheel 503 is rotated to drive the screw 501 to rotate. Under the limiting action of the second movable groove 6, the pressure block 502 on the surface of the screw 501 moves up and down along the screw 501. When the pressure block 502 moves downward, it engages with the top of the housing 1, pressing and fixing the speaker housing from the top and bottom. By turning the handwheel 503 in the opposite direction, the pressure block 502 moves upward, thus loosening the fixation on the housing. The operation is simple.

[0026] In this embodiment, as Figure 1 , Figure 4As shown, a self-locking motor 7 is fixedly connected to the inner wall of housing 2. A spur gear 8 is fixedly connected to the output end of the top of the self-locking motor 7. The spur gear 8 meshes with a gear sleeve 9. A cylinder 10 is fixedly connected to the inner wall of the gear sleeve 9. The top of the cylinder 10 extends to the top of housing 2 and is fixedly connected to the bottom of housing 1. The bottom and outer periphery of the cylinder 10 are rotatably connected to the inner wall of housing 2 through bearings. When the self-locking motor 7 is started, the output end of the self-locking motor 7 drives the spur gear 8 to rotate. The spur gear 8 meshes with the gear sleeve 9, thereby driving the gear sleeve 9 and the cylinder 10 to rotate. The top of the cylinder 10 is fixedly connected to housing 1. Therefore, the rotation of the cylinder 10 will drive housing 1 to rotate synchronously, realizing angle adjustment. After the adjustment is completed, the self-locking motor 7 self-locks, keeping housing 1 at the current angle. This makes it convenient for operators to process the speaker housing from different directions, improving the flexibility and convenience of processing.

[0027] In this embodiment, as Figure 2 As shown, a limiting rod 11 is fixedly connected to the inner wall of the housing 1. A transmission plate 405 is sleeved on the surface of the limiting rod 11. The inner wall of the transmission plate 405 is slidably connected to the surface of the limiting rod 11. When the bidirectional lead screw 404 drives the transmission plate 405 to move, the transmission plate 405 will slide along the surface of the limiting rod 11. The limiting rod 11 restricts the movement direction of the transmission plate 405.

[0028] In this embodiment, as Figure 1 , Figure 4 As shown, an auxiliary wheel 12 is fixedly connected to the bottom of housing 1. The outer periphery of the auxiliary wheel 12 is connected to the top of housing 2. When housing 1 rotates under the drive of cylinder 10, the outer periphery of the auxiliary wheel 12 will contact the top of housing 2 and roll, providing support for the rotation of housing 1 and reducing frictional resistance during rotation.

[0029] In this embodiment, as Figure 1 As shown, a rubber pad 13 is fixedly connected to the top of the housing 1. The rubber pad 13 can prevent direct contact between the speaker housing and the housing 1, reduce wear and scratches on the housing surface, and at the same time, the rubber pad 13 increases the friction between the housing and the housing 1, further improving the stability of the housing during the processing.

[0030] Specific usage process: In actual use, place the speaker housing on the rubber pad 13, then start motor 401. The output end of motor 401 drives bevel gear 402 to rotate. Bevel gear 402 meshes with bevel gear 403, thereby driving the bidirectional lead screw 404 to rotate. When the bidirectional lead screw 404 rotates, the transmission plate 405 on its surface will move relative to or towards each other along the axis of the bidirectional lead screw 404, thereby achieving the clamping or releasing action on both sides of the speaker housing, reducing manual operation. The complex design of the bidirectional lead screw 404 ensures the symmetry of the movement of the two transmission plates 405, making the clamping force more uniform and preventing damage to the housing due to uneven force. Then, after the first fixing mechanism 4 completes clamping on both sides, rotating the handwheel 503 drives the screw 501 to rotate. The pressure block 502 on the surface of the screw 501 moves up and down along the screw 501 under the limiting action of the moving groove 6. When the pressure block 502 moves downwards, it engages with the top of the housing 1, pressing and fixing the speaker housing from the top and bottom; rotating in the opposite direction... By moving the handwheel 503 upwards, the pressure block 502 can be loosened from the housing. The operation is simple and the height of the pressure block 502 can be flexibly adjusted according to the size of the speaker housing. The moving groove 6 ensures the stability of the movement of the pressure block 502 and prevents the pressure block 502 from shifting during the pressing process. The self-locking motor 7 can be activated as needed. When activated, the output end of the self-locking motor 7 drives the spur gear 8 to rotate. The spur gear 8 meshes with the gear sleeve 9, thereby driving the gear sleeve 9 and the cylinder 10 to rotate. The top of the cylinder 10 is fixedly connected to the housing 1, so the rotation of the cylinder 10 will drive the housing 1 to rotate synchronously, realizing angle adjustment. After the adjustment is completed, the self-locking motor 7 self-locks, keeping the housing 1 at the current angle. This allows the operator to process the speaker housing from different directions, improving the flexibility and convenience of processing. When the housing 1 rotates under the drive of the cylinder 10, the outer circumference of the auxiliary wheel 12 will contact the top of the housing 2 and roll, providing support for the rotation of the housing 1 and reducing the frictional resistance during the rotation process. In this invention, the first moving groove 3 provides a path for the movement of the first fixing mechanism 4. The first fixing mechanism 4 clamps and fixes the speaker housing from both sides, while the second fixing mechanism 5 cooperates with the housing 1 to fix the speaker housing from the top and bottom. Through the coordinated fixing in both sides and the vertical direction, the speaker housing is fixed, which solves the problem that traditional fixing devices can only fix the sides of the speaker housing and cannot fix the top of the speaker housing. This results in low applicability of traditional fixing devices and reduced work efficiency. This invention improves the versatility of the fixing device and enhances its fixing effect.
