Abstract
Description
Technical Field
[0001] This utility model relates to the field of audio technology, specifically to a multi-angle adjustable audio system. Background Technology
[0002] Wall-mounted speakers are speaker devices installed on a wall, primarily designed to save space and provide a high-quality audio experience. Their functions include enhancing the surround sound effect of a home theater or music system, optimizing sound field distribution, and maintaining a clean and aesthetically pleasing interior. They are suitable for environments such as living rooms, home theaters, and commercial spaces. Compared to traditional floor-standing or bookshelf speakers, wall-mounted designs save more space and, with proper installation, can improve the immersion and coverage of the sound.
[0003] The installation of wall-mounted speakers typically involves the following steps: First, determine the installation location, ensuring the wall can bear the weight and meets acoustic requirements; then, use a template or measuring tool to mark drilling points, drill holes in the wall, and install expansion screws or brackets; next, fix the speaker to the bracket and adjust the angle for optimal sound; finally, connect the audio cable and test the sound. Some models support drill-free adhesive or hanging installation, but stability may be slightly inferior. It is recommended to refer to the product manual or have it installed by a professional to ensure safety and sound quality. However, with existing speakers, the bracket must be installed first, and then the speaker fixed to the bracket. If the speaker angle needs to be adjusted, the speaker must be removed, the bracket angle adjusted, and then the speaker reinstalled, which is inconvenient and affects the adjustment and use of the speaker.
[0004] In view of this, we propose a multi-angle adjustable sound system. Utility Model Content
[0005] The purpose of this utility model is to provide a multi-angle adjustable speaker, which solves the problem of repeatedly adjusting the bracket angle when adjusting the speaker angle.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A multi-angle adjustable speaker includes a speaker body and a mounting bracket. The mounting bracket has screw holes on its surface for bolt fixing. It also includes a control component for stably adjusting the angle of the speaker body and ensuring its stability. The control component includes a fixed shaft located inside the mounting bracket and fixedly connected to it. A reinforcing rib is fixedly connected to the top surface of the fixed shaft, and the surface of the reinforcing rib is fixedly connected to the surface of the mounting bracket. A rotating sleeve passes through the bottom end of the fixed shaft and is rotatably connected to it. A connecting frame is fixedly connected to the surface of the rotating sleeve, and a bracket is fixedly connected to the surface of the connecting frame. An anti-detachment plate is fixedly connected to the end of the bracket away from the connecting frame.
[0008] Preferably, the inner side of the bracket is provided with a sliding groove, and a push plate passes through the bracket, with the push plate slidably connected to the bracket.
[0009] Preferably, a push rod is slidably connected to the inner side of the bracket, and the push rod passes through the connecting frame and is slidably connected.
[0010] Preferably, the end of the push rod near the push plate is fixedly connected to the surface of the push plate, and the end of the push rod away from the push plate is fixedly connected to a rack. A shaft is fixedly connected to the inner side of the connecting frame, and a sector gear is rotatably connected through the shaft, the sector gear meshing with the rack.
[0011] Preferably, a spring is fixedly connected to the surface of the push plate located inside the slide groove, and the end of the spring away from the push plate is fixedly connected to the inner side of the slide groove.
[0012] Preferably, the surface of the sector gear is fixedly connected with a hook, and the bottom surface of the fixed shaft is fixedly connected with a limit gear.
[0013] Preferably, the number of sector gears is two sets, and the two sets of sector gears are symmetrically arranged with the center line of the rack as the axis of symmetry, and the two sets of sector gears mesh with the rack evenly.
[0014] By employing the above technical solution, this utility model provides a multi-angle adjustable audio system. It possesses at least the following beneficial effects:
[0015] 1. This utility model allows the user to apply external force to push the push plate. The push plate slides along the groove on the inner side of the bracket and compresses the spring, while simultaneously driving the push rod fixedly connected to it to move. The linear motion of the push rod is transmitted to two sets of symmetrically arranged sector gears through the rack at the end, forcing the sector gears to rotate around the shaft. When the sector gears rotate, the hooks fixed on their surfaces disengage from the limiting gears on the bottom surface of the fixed shaft, thereby releasing the lock on the rotating sleeve. At this time, the rotating sleeve can rotate freely around the fixed shaft, driving the connecting frame, bracket and anti-detachment plate to rotate as a whole, realizing multi-angle adjustment of the speaker body.
[0016] 2. This utility model removes the external force from the push plate, causing the spring to rebound and push the push plate back to its original position. This, in turn, drives the rack to move back via the push rod. The rack then reverses, driving the sector gear to rotate, causing the hook to re-engage in the groove of the limiting gear, thus locking the rotating sleeve. At this point, the positions of the connecting frame and the bracket are fixed, and the speaker body remains stable at the new angle. The entire adjustment process achieves unidirectional force control through mechanical linkage. The push plate simultaneously performs unlocking and resetting functions, while the spring provides automatic locking force. The cooperation between the sector gear and the limiting gear ensures precise positioning at each angle. The design of two sets of symmetrical sector gears enhances transmission balance and prevents jamming, while the reinforcing ribs effectively distribute the force on the fixed shaft, preventing structural deformation over long-term use. This device converts the linear motion of the push plate into the rotational motion of the gears, and then achieves the dual functions of speaker angle adjustment and fixation through the meshing relationship between the hook and the limiting gear, ensuring both adjustment flexibility and speaker stability during operation.

[0026] 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.
[0027] A multi-angle adjustable speaker, such as Figure 1 - Figure 7As shown, the device includes a speaker body 1 and a mounting bracket 3. The surface of the mounting bracket 3 has screw holes for bolts to fix the speaker body 1. It also includes a control component 2 for stabilizing and adjusting the angle of the speaker body 1 and ensuring the stability of the speaker body 1. The control component 2 includes a fixed shaft 21, which is located inside the mounting bracket 3. During installation, the speaker is fixed to the desired position with bolts through the screw holes on the surface of the mounting bracket 3. The fixed shaft 21 inside the mounting bracket 3 is reinforced and connected to the mounting bracket 3 by a reinforcing rib 22 to ensure the overall structural stability. The fixed shaft 21 is fixedly connected to the mounting bracket 3. The top surface of the fixed shaft 21 is fixedly connected to the reinforcing rib 22. The surface of the reinforcing rib 22 is fixedly connected to the surface of the mounting bracket 3. The bottom end of the fixed shaft 21 has a rotating sleeve 23 through it. The rotating sleeve 23 is rotatably connected to the fixed shaft 21. The surface of the rotating sleeve 23 is fixedly connected to a connecting bracket 24. The surface of the connecting bracket 24 is fixedly connected to a bracket 25. The end of the bracket 25 away from the connecting bracket 24 is fixedly connected to an anti-detachment plate 26. A groove 27 is provided on the inner side of the bracket 25, and a push plate 28 passes through the bracket 25, which is slidably connected to the bracket 25. A push rod 29 is slidably connected to the inner side of the bracket 25, and the push rod 29 also passes through the connecting frame 24 and is slidably connected. The end of the push rod 29 near the push plate 28 is fixedly connected to the surface of the push plate 28, and the end of the push rod 29 away from the push plate 28 is fixedly connected to a rack 211. A shaft 212 is fixedly connected to the inner side of the connecting frame 24, and a sector gear 213 passes through and is rotatably connected to the shaft 212, which meshes with the rack 211. A spring 210 is fixedly connected to the surface of the push plate 28 located inside the slide groove 27. During the adjustment process, the bracket 25 prevents the speaker from falling off through the anti-detachment plate 26 to ensure safety. When the angle is adjusted to the correct position, the external force of the push plate 28 is removed, and the spring 210 rebounds to push the push plate 28 back to its original position. Then, the push rod 29 drives the rack 211 to move back. The rack 211 drives the sector gear 213 to rotate in the opposite direction, so that the hook 214 re-engages into the tooth groove of the limit gear 215, thus locking the rotating sleeve 23. At this time, the positions of the connecting frame 24 and the bracket 25 are fixed, and the end of the spring 210 away from the push plate 28 is fixedly connected to the inside of the slide groove 27. A hook 214 is fixedly connected to the surface of the sector gear 213, and a limit gear 215 is fixedly connected to the bottom surface of the fixed shaft 21. When the sector gear 213 rotates, the hook 214 fixed to its surface disengages from the limit gear 215 on the bottom surface of the fixed shaft 21, thereby releasing the lock on the rotating sleeve 23. At this time, the rotating sleeve 23 can rotate freely around the fixed shaft 21, driving the connecting frame 24, bracket 25 and anti-detachment plate 26 to rotate as a whole, realizing multi-angle adjustment of the speaker body 1.There are two sets of sector gears 213, and the two sets of sector gears 213 are symmetrically arranged with the center line of rack 211 as the axis of symmetry. When the sound angle needs to be adjusted, the user applies external force to push the push plate 28. The push plate 28 slides along the slide groove 27 on the inner side of the bracket 25 and compresses the spring 210. At the same time, it drives the push rod 29 fixedly connected to it to move. The linear motion of the push rod 29 is transmitted to the two sets of symmetrically arranged sector gears 213 through the rack 211 at the end, forcing the sector gears 213 to rotate around the shaft 212, and the two sets of sector gears 213 mesh with the rack 211 evenly.
[0028] In use, this multi-angle adjustable speaker is installed by bolting through the screw holes on the surface of the mounting bracket 3. The fixing shaft 21 on the inner side of the mounting bracket 3 is reinforced with the mounting bracket 3 by reinforcing ribs 22 to ensure the stability of the overall structure. When the speaker angle needs to be adjusted, the user applies external force to push the push plate 28. The push plate 28 slides along the slide groove 27 on the inner side of the bracket 25 and compresses the spring 210, which at the same time drives the push rod 29 fixedly connected to it to move. The linear motion of the push rod 29 is transmitted to the two ends through the rack 211 at the end. The symmetrically arranged sector gears 213 force the sector gears 213 to rotate around the shaft 212. When the sector gears 213 rotate, the hooks 214 fixed on their surfaces disengage from the limiting gears 215 on the bottom surface of the fixed shaft 21, thereby releasing the lock on the rotating sleeve 23. At this time, the rotating sleeve 23 can rotate freely around the fixed shaft 21, driving the connecting frame 24, bracket 25, and anti-detachment plate 26 to rotate as a whole, realizing multi-angle adjustment of the speaker body 1. During the adjustment process, the bracket 25 prevents the speaker from falling off through the anti-detachment plate 26, ensuring safety. When the angle is adjusted to the correct position... Afterwards, the external force on the push plate 28 is removed, and the spring 210 rebounds, pushing the push plate 28 back to its original position. This, in turn, drives the rack 211 to move back via the push rod 29. The rack 211 then drives the sector gear 213 to rotate in the opposite direction, causing the hook 214 to re-engage in the groove of the limiting gear 215, thus locking the rotating sleeve 23. At this point, the positions of the connecting bracket 24 and the bracket 25 are fixed, and the speaker body 1 remains stable at the new angle. The entire adjustment process achieves unidirectional force control through mechanical linkage. The push plate 28 simultaneously performs the unlocking and resetting functions, while the spring 210 provides automatic locking. The force, the cooperation between the sector gear 213 and the limiting gear 215 ensures that each angle can be accurately positioned. The design of two sets of symmetrical sector gears 213 enhances the transmission balance and prevents jamming, while the reinforcing rib 22 effectively disperses the force on the fixed shaft 21 and avoids structural deformation after long-term use. The device converts the linear motion of the push plate 28 into the rotational motion of the gears, and then realizes the dual function of adjusting and fixing the speaker angle through the meshing relationship between the hook 214 and the limiting gear 215. While ensuring the flexibility of adjustment, it also ensures the stability of the speaker during operation.
