Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically a concealed loudspeaker. Background Technology

[0002] In modern life, as people's requirements for quality of life and spatial aesthetics continue to improve, they also have new expectations for the appearance and installation of speakers. Traditional speakers usually have a relatively obvious appearance. Whether placed on a desktop or wall-mounted, they will occupy a certain amount of space and affect the overall spatial layout and aesthetics. For example, in some interior environments that pursue a simple decoration style, the abrupt appearance of traditional speakers is out of place with the overall decoration style. Therefore, speakers are usually installed in a hidden manner.

[0003] A search revealed a patent, CN206365019U, which discloses a ceiling-mounted loudspeaker. This loudspeaker includes an integrated frame with a magnetic circuit system directly embedded into it via injection molding. A transformer is installed inside the frame, and a mesh cover is provided on top. A wiring hole is also provided inside the frame, housing the loudspeaker wiring. This ceiling-mounted loudspeaker integrates the speaker frame and housing into a single unit, achieving lightweight construction, eliminating unnecessary resonance, improving sound quality, optimizing manufacturing processes, and increasing product yield. The spiral wiring hole on the back conceals excessively long cables, eliminating the possibility of contact with the loudspeaker's vibration system, and also integrates with on-site wiring, eliminating potential hazards.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] In the prior art, as described in the aforementioned comparative document, a flexible inclined bracket is used. During speaker installation, the ceiling mounting holes press against the inclined bracket. When the inclined bracket extends beyond the ceiling mounting holes, it pops out via a torsion spring, thus securing the speaker. However, this installation method relies on the spring force of the torsion spring, resulting in low stability of the speaker after installation. Furthermore, when the speaker needs to be disassembled and maintained later, it is necessary to reach into the upper part of the ceiling and press the inclined bracket back to its initial position, making subsequent disassembly and maintenance of the speaker quite troublesome. Therefore, there is an urgent need in the art to improve concealed speakers to overcome the shortcomings of the prior art. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a concealed speaker, which improves the stability of the speaker body after concealed installation and facilitates the disassembly and maintenance of the speaker body in the future.

[0030] 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.

[0031] Please see Figures 1-7 A concealed loudspeaker includes a loudspeaker body 1 mounted on a mounting base 2 at a concealed mounting hole 3. The loudspeaker body 1 has a mounting ring 4 on its side that matches the size of the concealed mounting hole 3. A plurality of rotating cylinders 5 are rotatably connected through and through the mounting ring 4. A first clamping plate 6 is fixedly mounted on the lower side of each rotating cylinder 5. A second clamping plate 7, matching the first clamping plate 6, is slidably connected to the upper side of each rotating cylinder 5. An adjusting threaded rod 8 extends into the rotating cylinder 5 and is used to drive the second clamping plate 7 to move up and down. A limiting nut 9 for limiting the position of the adjusting threaded rod 8 is threadedly connected to the lower side of the adjusting threaded rod 8. The rotating cylinder 5 has... The device includes a first rotating block 10, a mounting ring 4 with a first rotating groove 11 adapted to the first rotating block 10, a rotating cylinder 5 including two identical semi-cylinders 12, the lower end of the first rotating groove 11 passing through the mounting ring 4, and a plug 13 adapted to the semi-cylinder 12 being threadedly connected to the lower end of the first rotating groove 11. A sliding block 14 is fixedly installed at one end of the second clamping plate 7, and sliding grooves 15 adapted to the sliding block 14 are opened on the opposite sides of the two semi-cylinders 12. An adjusting threaded rod 8 passes through the sliding block 14 and is threadedly connected to it. A second rotating block 16 is fixedly installed on the side of the adjusting threaded rod 8, and a second rotating groove 17 adapted to the second rotating block 16 is opened on the opposite sides of the two semi-cylinders 12.

[0032] Specifically, when the speaker body 1 needs to be concealed and mounted on the mounting base plate 2, firstly, several rotating cylinders 5 are rotated. As the rotating cylinders 5 rotate, the first rotating block 10 rotates within the first rotating groove 11, rotating the first clamping plate 6 and the second clamping plate 7 on each rotating cylinder 5 towards the speaker body 1. The mounting ring 4 is then inserted into the concealed mounting hole 3 on the mounting base plate 2. The rotating cylinders 5 are then rotated, rotating the first clamping plates 6 and the second clamping plates 7 away from the speaker body 1. The adjusting threaded rod 8 is then rotated, and the second rotating block 16... Rotating within the second rotating groove 17, the adjusting threaded rod 8 drives the sliding block 14 to move within the sliding groove 15. The sliding block 14 drives the second clamping plate 7 to move towards the first clamping plate 6, locking the adjusting threaded rod 8. The first clamping plate 6 and the second clamping plate 7 clamp and fix the mounting base plate 2. The locking limit nut 9 limits and fixes the position of the adjusting threaded rod 8. By clamping the mounting base plate 2 at the upper and lower parts with several first clamping plates 6 and second clamping plates 7, the stability of the speaker body 1 after installation is improved. At the same time, when the speaker body 1 needs to be disassembled and maintained later, it can be rotated in the opposite direction. Adjusting the threaded rod 8 drives the second clamping plate 7 away from the first clamping plate 6. Then, rotating the rotating cylinder 5 again, so that the ends of the first clamping plate 6 and the second clamping plate 7 face the speaker body 1, allowing the speaker body 1 to be removed. This achieves the effect of concealed installation of the speaker body 1 and facilitates later disassembly and maintenance of the speaker body 1. When installing the rotating cylinder 5, the sliding block 14 is threaded onto the side of the adjusting threaded rod 8, merging the two semi-cylinders 12. The second rotating block 16 is located in the second rotating groove 17. The two semi-cylinders 12 are connected by the first rotation. Insert the lower end of the slot 11, install the second clamping plate 7 on the side of the sliding block 14 with screws or other connectors, thread the plug 13 to the lower end of the first rotating slot 11, install the semi-cylinder 12, and then install the whole device. This facilitates the assembly of the whole device. Each component can be produced separately and can be replaced and recycled, reducing the use cost and production cost of the whole device. The position of the second clamping plate 7 can be adjusted by adjusting the threaded rod 8, which can install the speaker body 1 on mounting base plates 2 of different thicknesses, thereby increasing the installation range of the speaker body 1.

[0033] As a technical optimization of this utility model, a shielding ring 18 adapted to the speaker body 1 is threadedly connected to the lower side of the mounting ring 4. The shielding ring 18 completely covers several rotating cylinders 5 and the first clamping plate 6. After the speaker body 1 is installed, the shielding ring 18 is threadedly connected to the lower side of the mounting ring 4 that extends beyond the mounting base plate 2. The shielding ring 18 is locked to shield several rotating cylinders 5 and the first clamping plate 6, improving the aesthetics of the overall device after installation. A mesh 19 adapted to the speaker body 1 is provided in the middle of the shielding ring 18, and the mesh 19 provides a protective effect.

[0034] As a technical optimization of this utility model, the lower part of the plug 13 is provided with a first locking block 20, which is polygonal in shape, making it easy to tighten the plug 13 with tools. The lower part of the two semi-cylinders 12 is provided with a second locking block 21, which is polygonal in shape, making it easy to rotate the rotating cylinder 5 with tools. The opposing sides of the first clamping plate 6 and the second clamping plate 7 are provided with anti-slip pads 22, which are elastic and improve the stability of the speaker body 1 after installation.
