Description

Technical Field

[0001] This utility model mainly relates to the field of speaker technology, specifically a ceiling-mounted iron rear-barrel speaker with an adjustable angle. Background Technology

[0002] A loudspeaker (also called a loudspeaker) is a transducer that converts electrical signals into sound signals. It uses the principle of electromagnetic induction to convert the input electrical signal into mechanical vibrations, which in turn cause the air to vibrate, creating the sound we hear.

[0003] Traditional ceiling speakers are mostly fixed in place, meaning that once installed, the speaker angle cannot be flexibly adjusted. This design cannot meet the diverse needs of different spatial layouts and usage scenarios. The fixed speaker angle cannot achieve optimal sound propagation, resulting in some areas having too little or uneven sound, thus affecting the listening experience. Utility Model Content

[0004] This utility model mainly provides a ceiling-mounted iron rear drum speaker with an easily adjustable angle, in order to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A ceiling-mounted iron rear drum speaker with adjustable angle includes a mounting plate. A transmission mechanism is provided on one side of the bottom of the mounting plate, and a driven mechanism is provided on the bottom of the mounting plate on the side of the transmission mechanism. A connecting rod is fixedly connected to the bottom of the driven mechanism, and a ceiling speaker is fixedly installed at the bottom end of the connecting rod. At the same time, a dustproof component is provided at one end of the ceiling speaker.

[0007] Preferably, the transmission mechanism includes a motor and a transmission gear, with the motor fixedly mounted on one side of the bottom of the mounting plate, and the output shaft of the motor connected to the transmission gear.

[0008] Preferably, the driven mechanism includes a mounting column and a driven gear. The mounting column is fixedly connected to the bottom of the mounting plate on one side of the transmission mechanism, and the driven gear is connected to the bottom of the mounting column through a rotating shaft. The bottom of the driven gear is fixedly connected to the top of the connecting rod.

[0009] Preferably, the driven gear meshes with the transmission gear.

[0010] Preferably, the bottom of the mounting plate has a limiting groove on the outside of the mounting column, and a limiting block is slidably assembled inside the limiting groove. The bottom of the limiting block is fixedly connected to a limiting rod, and the bottom end of the limiting rod is fixedly connected to the top of the driven gear.

[0011] Preferably, the dustproof component includes a mounting ring and a dustproof net, with the mounting ring mounted on one end of the ceiling speaker by bolts, and the dustproof net being fixedly installed inside the mounting ring.

[0012] Preferably, mounting rods are fixedly installed on all four sides of the top of the mounting plate, and mounting blocks are fixedly connected to both sides of the four mounting rods, with a mounting groove opened on one side of each mounting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By starting the drive motor, its output shaft drives the transmission gear to rotate. Since the transmission gear meshes with the driven gear, the rotation of the transmission gear drives the driven gear to rotate, which in turn drives the ceiling speaker to adjust its angle via the connecting rod. This allows the ceiling speaker to quickly adjust to the optimal sound emission angle according to different spatial layouts and usage scenarios, thereby improving the sound propagation effect and coverage.

[0015] 2. The dust filter effectively prevents dust from entering the ceiling speaker, avoiding any adverse effects on sound quality. It also protects the internal electronic components, ensuring that the ceiling speaker maintains good sound quality and performance throughout long-term use.

[0024] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0025] Example

[0026] Please refer to the appendix carefully. Figure 1-6A ceiling-mounted rear-mounted speaker with adjustable angle includes a mounting plate 1. Mounting rods 10 are fixedly mounted on all four sides of the top of the mounting plate 1 to provide stable support. Mounting blocks 11 are fixedly connected to both sides of each mounting rod 10. Each mounting block 11 has a mounting groove 12 on one side, which facilitates the secure fixing of the entire device to the ceiling with bolts or other fasteners, ensuring stability during use. A transmission mechanism 2 is located on one side of the bottom of the mounting plate 1. The transmission mechanism 2 includes a motor 201 and a transmission gear 202. The motor 201 is fixedly mounted on one side of the bottom of the mounting plate 1, and the output shaft of the motor 201 is connected to the transmission gear 202. When the motor 201 starts, the transmission gear 202 rotates, providing power for angle adjustment. A driven mechanism 3 is located on one side of the transmission mechanism 2 at the bottom of the mounting plate 1. The driven mechanism 3 includes a mounting post 301 and a driven gear 302. The mounting post 301 is fixedly connected to the bottom of the mounting plate 1, and the bottom of the mounting post 301 is connected to the driven gear 302 via a rotating shaft. The driven gear 302 is fixedly connected to the top of the connecting rod 4, and meshes with the transmission gear 202. When the transmission gear 202 rotates, it drives the driven gear 302 to rotate. A limit groove 7 is opened on the outside of the mounting post 301 at the bottom of the mounting plate 1. A limit block 8 is slidably assembled inside the limit groove 7. A limit rod 9 is fixedly connected to the bottom of the limit block 8, and the bottom end of the limit rod 9 is fixedly connected to the top of the driven gear 302, effectively preventing the driven gear 302 from shifting or shaking during rotation, thereby ensuring the angle adjustment. To ensure the precision and reliability of the connection, a ceiling speaker 5 is fixedly installed at the bottom of the connecting rod 4. At the same time, a dustproof component 6 is provided at one end of the ceiling speaker 5. The dustproof component 6 includes a mounting ring 601 and a dustproof mesh 602. The mounting ring 601 is bolted to one end of the ceiling speaker 5. The dustproof mesh 602 is fixedly installed inside the mounting ring 601. The dustproof mesh 602 can effectively block dust from entering the interior of the ceiling speaker 5, avoid dust from adversely affecting the sound quality, and also protect the internal electronic components, extending the service life of the ceiling speaker 5.

[0027] The specific operation method of this utility model is as follows:

[0028] In use, first use bolts to pass through the mounting slot 12 to fix the whole to the ceiling. When rotation is required, drive motor 201 to drive the transmission gear 202 to rotate. Since the transmission gear 202 meshes with the driven gear 302, the transmission gear 202 will drive the driven gear 302 to rotate, which in turn drives the ceiling speaker 5 to adjust the angle through the connecting rod 4. At the same time, the dustproof net 602 at the front end of the ceiling speaker 5 can prevent dust from entering the ceiling speaker 5 and affecting the sound quality or internal electronic components.

[0029] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
