Description

Technical Field

[0001] The present invention relates to the technical field of audio, and particularly relates to a ceiling-mounted audio and its installation structure. Background Art

[0002] Audio is a simplified daily term, which is an abbreviation of an audio system, that is, it refers to a complete set of devices that can restore and play audio signals. The application range of audio is extremely wide. In addition to using professional audio equipment in some large-scale vocal music performances, background music and public broadcast systems in places such as restaurants, teahouses, playgrounds, stations, and schools will also use audio equipment, and most of these audio are ceiling-mounted audio, with a wider sound propagation range and no occupation of extra effective space.

[0003] Since the ceiling-mounted audio is installed above the ceiling, it does not occupy the available indoor space, making the indoor layout more flexible. When installing the ceiling-mounted audio on the ceiling, the ceiling-mounted audio is fixed to the ceiling through springs and clamping blocks to achieve the effect of fixing and supporting the audio. However, when disassembling the ceiling-mounted audio, the gap between the ceiling-mounted audio and the ceiling is very small, and it is impossible to effectively trigger the clamping block to remove the ceiling-mounted audio, resulting in that the operator cannot perform rapid disassembly effectively, and more steps and tools are required to install or remove the audio equipment, resulting in an increase in the maintenance difficulty and time cost of the audio. In addition, after the audio is fixed to the ceiling, there will be a small gap inside the ceiling. When using the audio and vibrations occur upstairs, the audio will shake and vibrate. The vibration of the audio equipment may be directly transmitted to the building structure, causing other equipment or items to resonate or be interfered, resulting in noise or resonance in the surrounding environment, affecting the listening experience, causing wear or loosening, and shortening its lifespan.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By providing the first fixing ring, the card slot, the second fixing ring, the card block and the hinge bracket, the present invention can solve the problem that the operator cannot disassemble quickly and effectively, and more steps and tools are required to install or remove the audio equipment, resulting in an increase in the maintenance difficulty and time cost of the audio. By fixing the first fixing ring on the upper side wall of the gypsum board ceiling, placing the audio in the hole slot of the gypsum board ceiling and rotating it, the second fixing ring on the outer side of the audio will be driven to rotate, and the card block on the second fixing ring will rotate into the card slot inside the first fixing ring to fix the bottom of the audio. After the initial fixing, the hinge bracket on the top of the audio will support and fix the connecting column. After the connecting column is inserted into the engaging column, rotating the audio will drive the connecting column to rotate inside the engaging column. When rotating, the clamping column on the front side of the connecting column will slide in the hole slot of the engaging column. When the clamping column slides to the left side of the hole slot, it will support and fix the clamping column and drive the limiting effect to fix the top of the audio. When disassembly is required, rotating the second fixing ring on the outer side of the audio again will drive the card block to leave the inside of the card slot, and at the same time, the rotating connecting column will drive the clamping column to slide into the left side of the hole slot, and then pull the audio out of the hole slot of the gypsum board ceiling downward, so as to achieve the effect of quick installation and disassembly, thereby effectively improving its use flexibility, reducing the maintenance cost and reducing the possible damage risk.

[0017] 2. The present invention, through the sleeve, electric push rod, telescopic rod, guide rail, limit block and slide rail provided, can solve the problem that its height cannot be adjusted, which may limit the audio coverage range, limit the flexible layout of the indoor space, resulting in poor sound quality or no coverage in some areas. Additionally, the rotating disk inside is supported by the support column on the bottom wall of the ceiling, enabling the rotating disk to be supported inside the support column. The electric push rod is supported and fixed by the sleeve on the bottom wall of the rotating disk. The telescopic rod on the telescopic end of the electric push rod drives the bottom joint column to connect with the connection column and drives it to move up and down. Moreover, the guide rail is supported and fixed by the joint blocks on the left and right sides of the bottom wall of the rotating disk. The slide rail slides inside the guide rail, and the rotating shaft at the bottom of the slide rail is connected to the left and right sides of the speaker to drive the speaker to adjust its height up and down. When the slide rail descends to a certain extent, the top block on the top of the slide rail corresponds to the limit block at the bottom of the guide rail, and the limit block achieves the limiting effect to prevent damage to the device caused by excessive lowering. Through the setting of the rotating shaft and the hinge frame, the speaker can be driven to adjust its orientation, improving the audio coverage range of the speaker, thereby effectively enhancing flexibility, functionality, convenience of installation position, maintenance and adjustment, and the layout of the indoor space.

[0018] 3. Through the setting of the lower seat plate, lower arc panel, first spherical crown lining plate, first lower slide plate and intermediate body, the problems that resonance or interference is caused to other devices or articles, noise or resonance is generated in the surrounding environment, affecting the listening experience, wear or looseness is caused, and its service life is shortened can be solved. By fixing the bottom plate on the upper side wall of the gypsum board ceiling, when the electric push rod drives the joint column to move up and down, the support plate is fixed on the outside of the joint column. The grooves inside the left and right sides of the support plate will drop to the outside of the upper seat plate. When vibration occurs, the left and right sides of the intermediate body slide on the first sliding friction pair on the inner wall of the lower seat plate. Through the first spherical crown lining plate on the upper part of the lower arc panel inside the lower seat plate, the bottom of the intermediate body is supported and slides. The intermediate body slides on the first spherical crown lining plate and the first sliding friction pair to generate friction and buffer the bottom of the intermediate body. Then, the second upper slide plate on the top of the intermediate body fixes and supports the second spherical crown lining plate. When vibration and shaking occur, the second sliding friction pair on the top of the second spherical crown lining plate provides support, and the inside of the upper seat plate slides on the upper side wall of the second sliding friction pair to achieve the effects of shock absorption and anti-shaking, thereby effectively enhancing the stability, sound quality and safety of the ceiling-mounted speaker and its installation structure, improving the user's listening experience and extending the service life of the device.

A sleeve 14 is fixedly connected to the bottom of the rotating disk 13. The sleeve 14 is fixed, and the rotating disk 13 drives the sleeve 14 to rotate. An electric push rod 15 is fixedly connected to the inside of the sleeve 14. The sleeve 14 is used to support and fix the electric push rod 15. The telescopic end of the electric push rod 15 is fixedly connected to a telescopic rod 16. The other end of the telescopic rod 16 is fixedly connected to a joint column 11. The telescopic rod 16 is used to drive the joint column 11 for support and fixation and drive the joint column 11 to move up and down. A hole slot 34 is provided on the front side wall of the joint column 11. The clamping column 10 is slidably connected inside the hole slot 34. The joint column 11 and the connecting column 9 are arranged correspondingly. After the connecting column 9 is placed inside the joint column 11, the clamping column 10 will slide in the hole slot 34 on the joint column 11. When it slides to the left side of the hole slot 34, it will support the top of the speaker 1 and the connecting column 9. When the clamping column 10 slides to the right side of the hole slot 34, the support will be released. By pulling the speaker 1 downward, the connecting column 9 will drive the clamping column 10 to leave the joint column 11 to achieve the disassembly effect.

[0035] As Figure 1 - Figure 8As shown, engaging blocks 17 are fixedly connected to both the left and right sides of the bottom wall of the rotating disk 13. By fixing the engaging blocks 17 on the rotating disk 13, the engaging blocks 17 are supported and fixed. Guide rails 18 are fixedly connected to the bottoms of both engaging blocks 17. By fixing the guide rails 18 on the engaging blocks 17, the guide rails 18 are supported and fixed. A limiting block 19 is fixedly connected to the bottom of the guide rail 18. By providing the limiting block 19, the sliding rail 20 sliding inside is limited to prevent damage caused by excessive sliding. Sliding rails 20 are slidably connected to the interiors of both guide rails 18. Top blocks 21 are fixedly connected to the tops of both sliding rails 20. The two top blocks 21 and the limiting block 19 are arranged corresponding to each other. By providing the top blocks 21 to correspond to the limiting block 19, when the sliding rail 20 drives the top block 21 to slide downward, the top block 21 will contact the upper side wall of the limiting block 19, thereby achieving the limiting effect. Rotating shafts 22 are fixedly connected to the bottoms of both sliding rails 20. The other ends of the two rotating shafts 22 are rotatably connected to the left and right sides of the speaker 1. By fixing the rotating shafts 22 at the bottoms of the sliding rails 20 to the left and right sides of the speaker 1, when the fixing of the speaker 1 is released, the speaker 1 is driven to lift and adjust the direction.

[0036] As Figure 1 - Figure 9 As shown, a support plate 23 is fixedly connected to the outer side of the top end of the engaging column 11. By fixing the support plate 23 on the outer side of the engaging column 11, the support plate 23 is driven to slide up and down. Grooves 33 are formed in both the left and right sides of the bottom wall of the support plate 23. When descending, the insides of the grooves 33 will fall onto the outer sides of the upper seat plates 32.

[0037] As Figure 1 - Figure 11As shown, bottom plates 24 are fixedly connected to both the front and rear sides of the top wall of the gypsum board ceiling 2. The bottom plates 24 are provided to support the devices at the top. Lower seat plates 25 are fixedly connected to the tops of the two bottom plates 24. The lower seat plates 25 are provided to protect the internal devices. Lower arc-shaped panels 26 are fixedly connected to the interiors of the two lower seat plates 25. The lower arc-shaped panels 26 are provided to support the devices at the top from the bottom. First spherical crown liners 27 are fixedly connected to the outer sides of the tops of the two lower arc-shaped panels 26. The first spherical crown liners 27 are provided to enhance the protection at the bottom. First lower sliding plates 28 are fixedly connected to the tops of the two first spherical crown liners 27. Intermediate bodies 29 are provided inside the two lower seat plates 25. The bottoms of the two intermediate bodies 29 are slidably connected to the tops of the first lower sliding plates 28. By sliding the tops of the intermediate bodies 29 on the outer sides of the first lower sliding plates 28, friction is generated to improve the anti-shaking effect. First sliding friction pairs 36 are slidably connected to the left and right sides of the two intermediate bodies 29. The other sides of the four first sliding friction pairs 36 are fixedly connected to the left and right sides of the inner walls of the lower seat plates 25. By slidably connecting the left and right sides of the intermediate bodies 29 to the first sliding friction pairs 36, friction is generated to reduce the frequency during shaking.

[0038] As Figure 1 - Figure 11 As shown, second upper sliding plates 30 are fixedly connected to the top walls of the two intermediate bodies 29. By fixing the second upper sliding plates 30 on the intermediate bodies 29, the second upper sliding plates 30 can be supported and fixed. Second spherical crown liners 31 are fixedly connected to the interiors of the two second upper sliding plates 30. Second sliding friction pairs 35 are fixedly connected to the tops of the two second spherical crown liners 31. Upper seat plates 32 are provided inside the two grooves 33. By setting that the grooves 33 will fall onto the outer sides of the upper seat plates 32 after descending, the devices can be supported. The bottoms of the two upper seat plates 32 are slidably connected to the tops of the second sliding friction pairs 35. When vibration occurs, the bottoms of the upper seat plates 32 will slide on the top walls of the second sliding friction pairs 35 to reduce the vibration frequency.

[0039] It should be noted that the present invention relates to a ceiling-mounted speaker and its installation structure. First, the first fixing ring 4 is fixed to the upper side wall of the gypsum board ceiling 2. The speaker 1 is placed in the hole groove of the gypsum board ceiling 2 and rotated. The second fixing ring 6 on the outer side of the speaker 1 will be driven to rotate, and the clamping block 7 on the second fixing ring 6 will rotate into the clamping groove 5 inside the first fixing ring 4 to fix the bottom of the speaker 1. After preliminary fixing, the hinge frame 8 on the top of the speaker 1 will support and fix the connecting column 9. After the connecting column 9 is inserted into the inside of the joint column 11, the speaker 1 is rotated to drive the connecting column 9 to rotate inside the joint column 11. When rotating, the clamping column 10 on the front side of the connecting column 9 will slide in the hole groove 34 of the joint column 11. When the clamping column 10 slides to the left side of the hole groove 34, it will support and fix the clamping column 10 and drive the limiting effect to fix the top of the speaker 1. When disassembly is required, rotating the second fixing ring 6 on the outer side of the speaker 1 again will drive the clamping block 7 to leave the inside of the clamping groove 5. At the same time, the rotating connecting column 9 will drive the clamping column 10 to slide into the left side of the hole groove 34, and then the speaker 1 is pulled out from the hole groove of the gypsum board ceiling 2 downward, so as to achieve the effects of quick installation and disassembly.

[0040] In addition, the rotating disk 13 inside is supported by the support column 12 on the bottom wall of the ceiling 3, so that the rotating disk 13 can be supported inside the support column 12. The electric push rod 15 is supported and fixed by the sleeve 14 on the bottom wall of the rotating disk 13. The telescopic rod 16 on the telescopic end of the electric push rod 15 drives the bottom joint column 11 to be connected with the connecting column 9 and drives it to move up and down. In addition, the guide rail 18 is supported and fixed by the joint blocks 17 on the left and right sides of the bottom of the rotating disk 13. The sliding rail 20 slides inside the guide rail 18. The rotating shaft 22 at the bottom of the sliding rail 20 is connected to the left and right sides of the speaker 1 to drive the speaker 1 to adjust the height up and down. When the sliding rail 20 descends to a certain extent, the top block 21 on the top of the sliding rail 20 will correspond to the limiting block 19 at the bottom of the guide rail 18, and the limiting effect is achieved through the limiting block 19 to prevent damage to the device caused by excessive lowering. Through the setting of the rotating shaft 22 and the hinge frame 8, the speaker 1 can be driven to adjust its orientation to improve the audio coverage range of the speaker 1.

[0041] By fixing the bottom plate 24 to the upper side wall of the gypsum board ceiling 2, when the electric push rod 15 drives the engagement column 11 to move up and down, the support plate 23 is fixed to the outside of the engagement column 11. Through the grooves 33 inside the left and right sides of the support plate 23, it will drop to the outside of the upper seat plate 32. When vibration occurs, the left and right sides of the intermediate body 29 will slide on the first sliding friction pair 36 on the inner wall of the lower seat plate 25. Through the first spherical crown lining plate 27 on the upper part of the lower arc panel 26 inside the lower seat plate 25, the bottom of the intermediate body 29 is supported and slid. The intermediate body 29 slides on the first spherical crown lining plate 27 and the first sliding friction pair 36 to generate friction to buffer the bottom of the intermediate body 29. Through the second upper slide plate 30 at the top of the intermediate body 29, the second spherical crown lining plate 31 is fixed and supported. When vibration and shaking occur, the second sliding friction pair 35 at the top of the second spherical crown lining plate 31 will support. Through the inside of the upper seat plate 32, it will slide on the upper side wall of the second sliding friction pair 35 to achieve the effects of earthquake prevention and anti-shaking.
