[0002] A digital amplifier is a device that uses digital signal processing technology to amplify audio signals. It converts the input analog audio signal into a digital signal, then processes the digital audio signal through a digital signal processor (DSP), performing operations such as amplification, filtering, equalization, and mixing. Finally, the processed digital signal is converted back into an analog signal, amplified by a power amplifier, and then used to drive speakers to produce sound.

[0003] Wall-mounted amplifiers are installed directly on the wall, without taking up floor or desktop space. This installation method can make the room layout neater and more beautiful, and allows users to flexibly adjust the installation position according to their needs to achieve the best audio playback effect.

[0004] Traditional wall-mounted digital amplifiers typically require bolts to be fixed to the mounting arm. This method of fixing is extremely inconvenient during equipment maintenance and cleaning. When cleaning is required, personnel must use ladders to climb up and remove multiple sets of bolts to remove the equipment from the mounting arm. This is not only cumbersome and time-consuming, but also reduces disassembly efficiency. Therefore, a wall-mounted digital amplifier is proposed to solve the above problems. Utility Model Content

[0031] 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.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a wall-mounted digital amplifier, including a suspension 1, which is bolted to the wall, thereby suspending the amplifier body 2. The amplifier body 2, which is a digital amplifier, is mounted on the upper part of the suspension 1 to process and amplify audio signals. A support leg 3 is fixedly connected to the lower part of the amplifier body 2. A mounting hole 4 is provided through the upper part of the suspension 1, and the support leg 3 is inserted into the inner wall of the mounting hole 4. The support leg 3 cooperates with the mounting hole 4 to stably mount the amplifier body 2 on the suspension 1. A limit component 5 is provided on the outer side of the suspension 1. 5 includes a fixed block 51 fixedly connected to the outside of the suspension 1, which provides stable structural support for the entire limiting assembly 5. The fixed block 51 has a groove 52 on its outer side, which provides space for the movement of the limiting member 53 and prevents the limiting member 53 from detaching from the fixed block 51. The groove 52 is L-shaped, and the front part of the L-shape of the groove 52 extends downward and penetrates the lower part of the fixed block 51, so that the limiting member 53 can rotate downward. An auxiliary component 6 is provided on the outer side of the fixed block 51 near the groove 52. The inner wall of the groove 52 slides and rotates to connect with the limiting member 53.

[0033] Reference Figure 1 - Figure 3 The limiting member 53 is L-shaped, and its lower part is spherical for easy operation. By inserting into the inner wall of the limiting hole 54, it can limit the support leg 3, thereby fixing the body 2 and facilitating disassembly. The limiting member 53 slides through the inner wall of the fixing block 51. The support leg 3 has a limiting hole 54 extending through it in the front-rear direction, which engages with the limiting member 53. Through this tight engagement, the body 2 is securely fixed to the suspension 1, ensuring the amplifier remains stable during use. The limiting member 53 is inserted into the inner wall of the limiting hole 54. A damping pad 55 is fixedly connected to the lower inner wall of the slide groove 52 to increase the damping of the limiting member 53 when it slides within the slide groove 52, thus ensuring the stability of the limiting member 53. 3. After adjustment, it can stably maintain its current position, avoiding accidental sliding of the limiting component 53 due to external vibrations and other factors, thereby ensuring the stability of the installation of the body 2. The left and right sides of the damping pad 55 are set as inclined surfaces. The inclined surfaces facilitate the smooth contact and separation of the limiting component 53 with the damping pad 55 when sliding, improving the convenience of operation. The limiting component 5 also includes a rubber pad 56, which is fixedly connected to the upper part of the suspension 1. The upper part of the rubber pad 56 contacts the outside of the body 2, mainly playing the role of buffering and shock absorption, reducing the vibration generated by the body 2 during operation and transmitting it to the suspension 1, avoiding loosening of parts and noise caused by vibration, and also protecting the contact parts between the body 2 and the suspension 1 to prevent scratches and wear.

[0034] Reference Figure 2 - Figure 4 The auxiliary component 6 includes a connecting post 61 fixedly connected to the outside of the fixed block 51 for supporting the cover plate 62. The cover plate 62 is rotatably connected to the inner wall of the connecting post 61. The cover plate 62 contacts and adheres to the outside of the fixed block 51. Under the action of the torsion spring 63, it is tightly adhered to the outside of the fixed block 51. Its main function is to prevent dust and debris from entering the slide groove 52, avoiding affecting the sliding and rotation of the limiting member 53, thereby extending the service life of the equipment. When the limiting member 53 needs to be operated, the limiting member 53 rotates to squeeze and drive the cover plate 62 to rotate and open. No additional manual operation is required. The design is ingenious and convenient. The cover plate 62 is elastically connected to the connecting post 61 through the torsion spring 63, which provides elastic restoring force to the cover plate 62. When the cover plate 62 is not subjected to external force, it always remains in contact with the outside of the fixed block 51, effectively blocking dust and debris. Multiple sets of connecting posts 61 and torsion springs 63 are provided, and multiple sets of connecting posts 61 and torsion springs 63 are respectively set on the front and rear sides of the cover plate 62.

[0035] Working principle: When in use, first fix the suspension 1 to the wall with bolts, align the support leg 3 at the bottom of the body 2 with the mounting hole 4 at the top of the suspension 1 and insert it to initially connect the body 2 and the suspension 1. Then operate the limiting component 5, rotate and move the L-shaped limiting part 53, so that its lower spherical part slides and rotates along the L-shaped slide groove 52 until the limiting part 53 is inserted into the limiting hole 54 of the support leg 3.

[0036] During this process, the damping pad 55 on the lower inner wall of the slide 52 plays a role. Its inclined surface design facilitates the smooth sliding of the limiting member 53, while the damping characteristics prevent the limiting member 53 from accidentally sliding due to external vibration after it moves into place, ensuring that the body 2 is firmly fixed on the suspension 1 and avoiding shaking or displacement during use. The rubber pad 56 on the upper part of the suspension 1 can buffer the vibration generated when the body 2 is working, reduce component loosening and noise, and protect the contact parts.

[0037] Under the elastic action of the torsion spring 63, the cover plate 62 of the auxiliary component 6 fits tightly against the outside of the fixed block 51, sealing the opening of the slide groove 52, effectively preventing dust and debris from entering, avoiding affecting the normal sliding and rotation of the limit component 53, and extending the service life of the equipment.

[0038] When the limiting member 53 needs to be adjusted for installation or disassembly of the machine body 2, the rotation of the limiting member 53 will squeeze the cover plate 62, causing the cover plate 62 to rotate around the connecting column 61 and open. After the operation is completed, the torsion spring 63 will drive the cover plate 62 to quickly return to its original position, without the need for additional manual operation.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
