Description

Technical Field

[0001] This utility model relates to the field of sound-absorbing panel technology, and in particular to a sound-absorbing panel wall-mounting module assembly. Background Technology

[0002] In the field of architectural acoustics, sound-absorbing panels are widely used in homes, offices, shopping malls, factories and other places to reduce environmental noise and improve the acoustic environment.

[0003] In existing technologies, common sound-absorbing panels are mostly made of materials such as polyester fiber into a single-piece structure, which is directly pasted or fixed to the wall. However, this type of single-piece sound-absorbing panel has obvious drawbacks. The single-piece pasted polyester fiber board mainly utilizes the sound absorption characteristics of porous materials, which has a good absorption effect on mid- and high-frequency sound waves, but its absorption efficiency for low-frequency sound waves is significantly reduced. According to acoustic principles, a "plate-cavity" structure can form a resonant sound absorption system. When a sound wave is incident, the plate (or membrane) will bend and vibrate, while the air in the sealed cavity behind it acts as a "spring". When the frequency of the sound wave matches the natural resonant frequency of the system, it will cause strong resonance between the plate and the air in the cavity, thereby consuming a large amount of sound energy through internal friction and acoustic resistance. Therefore, the main disadvantages of existing sound-absorbing panels can be summarized as: insufficient sound absorption performance (especially low-frequency sound absorption performance) and lack of optimized resonant cavity design. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to overcome the problem that the sound absorption effect of a single sound-absorbing panel in the prior art cannot effectively absorb low-frequency sound waves, resulting in a significant reduction in sound absorption capacity. Therefore, a wall-mounted sound-absorbing panel module assembly is provided, which improves the sound absorption capacity of a single sound-absorbing panel by forming a sound-absorbing cavity, and can also achieve excellent sound absorption effect for low-frequency sound waves.

[0005] To solve the above-mentioned technical problems, this utility model provides a sound-absorbing panel wall-mounting module assembly, comprising: The panel body serves as the base plate for mounting sound-absorbing components; A sound-absorbing component is connected to the panel body. The sound-absorbing component includes several support parts, and a sound-absorbing cavity is formed between the surface of the several support parts and the panel body. The distance between the thickness of the several support parts and the panel body forms the height of the sound-absorbing cavity. An adhesive structure is provided on both sides of the plate body along its length, the adhesive structure including a limiting groove, and several of the supporting parts are fitted into the limiting groove; The support portion is made of polyester limiting material.

[0006] In one embodiment of the present invention, the adhesive structure further includes an adhesive plate, which is disposed on both sides of the plate body along its length, and the adhesive plate has a mating groove that mates with the side of the support portion.

[0007] In one embodiment of this utility model, the limiting groove is a "V" shaped groove.

[0008] In one embodiment of the present invention, the sound-absorbing component includes a plurality of slots disposed on the plate body, the slots being fitted into the support portion.

[0009] In one embodiment of the present invention, a plurality of the slots are arranged in an array along the width direction of the plate body, and limiting plates are provided on both sides extending in the width direction of the plate body.

[0010] In one embodiment of this utility model, the cross-section of the slot is rectangular.

[0011] In one embodiment of this utility model, the width of the sound-absorbing cavity is greater than the distance between the two limiting grooves.

[0012] In one embodiment of this utility model, the module group further includes a fixing plate, on which several fixing grooves are formed, and the area and shape of the fixing plate are the same as those of the plate body.

[0013] In one embodiment of this utility model, a self-tapping screw is provided in the fixing groove, and the nut of the self-tapping screw is made of iron.

[0014] In one embodiment of this utility model, a strong magnet is provided on the plate body facing the direction of the self-tapping screw.

[0015] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects: The fluorescent signal detection device described in this utility model is used to enhance the sound absorption effect of a single sound-absorbing panel, preventing the single sound-absorbing panel from failing to effectively alleviate low-frequency noise during use. This makes the sound absorption effect of the sound-absorbing panel significantly decrease when low-frequency sound waves are generated in the environment, enabling the sound-absorbing panel to absorb low-frequency noise and improving the sound absorption effect of the single sound-absorbing panel on the wall for low-frequency noise. The design incorporates sound-absorbing components, which, through the cooperation of several support parts, form a sound-absorbing cavity. This cavity enhances the resonance time of noise within the sound-absorbing panel, creating a highly efficient resonant chamber. When high-frequency noise is emitted from the outside, the cavity resonates, reducing the amplitude of the sound and thus decreasing the propagation distance of low-frequency noise. Consequently, it reduces the impact of low-frequency noise on the indoor environment. The support parts are made of polyester fiber, which has low conductivity and excellent sound insulation properties, further enhancing the sound insulation capability of a single sound-absorbing panel against low-frequency sound waves.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0019] The purpose of this invention is to solve the problems of existing sound-absorbing panels having a simple structure, limited sound absorption effect, and inability to absorb low-frequency noise. Traditional single-piece polyester fiber sound-absorbing panels are tightly attached to the wall and lack an effective cavity structure, resulting in a narrow sound absorption band, especially poor absorption of low-frequency noise. At the same time, their installation often relies on adhesives or complex keel systems, which not only damages the wall but also makes it difficult for users to install and replace them conveniently. This invention aims to provide a solution for low-frequency sound wave processing through a modular sound-absorbing panel wall module design.

[0020] refer to Figure 1 , 3 As shown, specifically, it includes a panel body 1, which serves as a base plate for mounting a sound-absorbing component 2; the sound-absorbing component 2, which is connected to the panel body 1, includes several support parts 21, and a sound-absorbing cavity 22 is formed between the several support parts 21 and the surface of the panel body 1, the distance between the thickness of the several support parts 21 and the panel body 1 forms the height of the sound-absorbing cavity 22; and an adhesive structure 3, which is disposed on both sides of the panel body 1 along its length, the adhesive structure 3 including a limiting groove 31, into which several support parts 21 are fitted; wherein, the support parts 21 are made of polyester fiber material.

[0021] refer to Figure 1 , 3 As shown, this modular assembly mainly comprises three functional parts: the panel body 1, the sound-absorbing components 2, and the adhesive structure 33. The panel body 1 serves as the structural foundation and mounting base of the entire modular assembly. It is typically a rectangular panel structure, and its material can be medium-density fiberboard, plastic, or metal, which possesses a certain rigidity and strength to ensure the stability of its overall shape after installation and prevent deformation from affecting its sound absorption performance. The sound-absorbing components 2 are the core of the sound absorption function and are fixedly connected to the panel body 1. The sound-absorbing components 2 include several support parts 21. These support parts 21 are preferably made of polyester fiber sound-absorbing cotton, polyurethane foam, or other porous sound-absorbing materials, which can effectively absorb audio. They are arranged in an array along the length of the sound-absorbing panel and bonded to the surface of the panel body 1, collectively enclosing several independent sound-absorbing cavities 22. The thickness of the support portion 21 directly determines the height of the sound-absorbing cavity 22, which affects the sound absorption effect. This height is primarily used to adjust the resonant sound absorption frequency of the system, thereby specifically absorbing noise in specific frequency bands, especially low frequencies. The adhesive structure 3 is located on both sides of the panel body 1 along its length. Its main function is to achieve a quick, secure, and detachable connection between the module assembly and the wall surface. The adhesive structure 3 includes a limiting groove 31, which is used to engage with the edge of the support portion 21 of adjacent module assemblies, thereby achieving rapid positioning and seamless splicing between modules, ensuring the overall aesthetics and acoustic continuity of the wall surface.

[0022] refer to Figure 2 , 3 As shown, the adhesive structure 3 also includes an adhesive plate 32, which is disposed on both sides of the board body 1 along its length. The adhesive plate 32 has a mating groove 33 that mates with the side of the support part 21. The limiting groove 31 is a "V" shaped groove. The sound absorption component 2 includes several slots 11 disposed on the board body 1. The slots 11 and the support part 21 are fitted together. The several slots 11 are arranged in an array along the width direction of the board body 1. Limiting plates 12 are disposed on both sides of the board body 1 extending in the width direction. The cross-section of the slots 11 is rectangular.

[0023] refer to Figure 2 , 3 As shown, in a preferred embodiment of this utility model, the sound-absorbing component 2 is implemented as follows: several slots 11 are pre-cut on the surface of the panel body 1 by means of carving, molding, or bonding. These slots 11 are preferably arranged in a uniform array along the width direction of the panel body 1. The support part 21 is a strip block that matches the shape of these slots 11 and is installed in the slots 11 by embedding or bonding. When the support part 21 is installed in place, its top surface is higher than the surface of the panel body 1, thereby naturally forming a sound-absorbing cavity 22 between the top surface of the support part 21 and the wall surface to be installed. The strip structure of the support part 21 divides the entire large cavity into multiple parallel narrow and long cavities, which helps to suppress the lateral propagation of sound waves in the cavity, reduce the generation of standing waves, and improve the mid-to-low frequency sound absorption coefficient.

[0024] refer to Figure 2 , 3 As shown, the cross-sectional shape of the slot 11 can be rectangular, trapezoidal, or dovetail-shaped, etc. In a specific embodiment, a rectangular cross-section slot 11 is used, which is easy to process and provides a stable fit with the rectangular strip-shaped support 21.

[0025] refer to Figure 2 , 3 As shown, to ensure the stability of the module assembly during installation, integrally formed or post-installed limiting plates 12 are provided on both sides of the panel body 1 extending along the width direction. When the module assembly is pushed towards the wall, these limiting plates 12 first contact the wall, playing a role in initial positioning and preventing the module assembly from being over-pressed in, which would cause the sound-absorbing cavity 22 to be compressed, thus ensuring the stability of the cavity height.

[0026] refer to Figure 2 , 3As shown, the adhesive structure 3 in this embodiment further includes an adhesive plate 32. The adhesive plate 32 is fixed to both sides of the plate body 1 along its length by screws or strong adhesive. A limiting groove 31 is provided on the adhesive plate 32. This limiting groove 31 is designed as a "V" shaped groove. The "V" shaped groove design has a self-guiding function; when splicing two modules, even with minor installation errors, it can guide the edges of the support parts 21 of adjacent modules to smoothly slide into the bottom of the groove, achieving precise alignment. At the same time, the "V" shaped surface contact provides greater adhesive or snap-fit ​​force, enhancing the connection strength between module groups and effectively avoiding joint cracking caused by temperature and humidity changes or slight vibrations.

[0027] refer to Figure 3 , 4 As shown in Figure 5, the width of the sound-absorbing cavity 22 is greater than the distance between the two limiting grooves 31. The module group also includes a fixing plate 4, on which several fixing grooves 41 are opened. The area and shape of the fixing plate 4 are the same as the area and shape of the plate body 1.

[0028] refer to Figure 3 , 4 As shown in Figure 5, the width of the sound-absorbing cavity 22 is greater than the distance between the two limiting grooves 31, ensuring that the effective sound-absorbing area inside a single module is much larger than the seam area between modules. Even if seams exist, their impact on the overall acoustic performance is minimized, ensuring the uniformity and consistency of the sound absorption effect across the entire installation wall surface.

[0029] refer to Figure 3 , 4 As shown in Figure 5, the module assembly also includes a fixing plate 4. The fixing plate 4 is a thin plate with the same area and shape as the main body 1, and can be made of plastic or metal. Several fixing grooves 41 are formed on the fixing plate 4. The fixing grooves 41 provide sufficient support while avoiding conflict with the sound-absorbing cavity 22 behind the main body 1.

[0030] refer to Figure 3 , 4 As shown in Figure 5, a self-tapping screw 42 is provided in the fixing groove 41. The nut of the self-tapping screw 42 is made of iron. A strong magnetic component is provided on the plate body 1 facing the direction of the self-tapping screw 42.

[0031] refer to Figure 3 , 4As shown in Figure 5, a strong magnetic component is embedded on the side of the panel body 1 facing the wall, corresponding to the position of the head of the self-tapping screw 42 on the fixing plate 4. The strong magnetic component is preferably a neodymium iron boron permanent magnet due to its extremely high magnetic energy product. To facilitate the attraction of the strong magnetic component, the nuts of the self-tapping screw 42 are made of materials such as iron or stainless steel that can be attracted by magnets. During installation, the sound-absorbing panel wall-mounted module assembly is lifted, and the strong magnetic component on its back is roughly aligned with the nut position of the self-tapping screw 42 on the fixing plate 4, then brought close to the wall. The magnetic force will automatically guide the module assembly to accurately adhere in place.

[0032] When installing this module, first position it on the wall. Secure the fixing plate 4 to the predetermined position on the wall using self-tapping screws 42 through its fixing groove 41. Then, a single person can hold the sound-absorbing panel module and bring the strong magnet on its back close to the iron nut on the fixing plate 4. Under magnetic force, the module will be attracted and positioned. When installing multiple modules, use the "V"-shaped limiting grooves 31 on the adhesive structures 3 on both sides of the panel body 1 to slide the edge of the support part 21 of the module to be installed into the limiting groove 31 of the already installed module, achieving quick alignment and seamless splicing between modules. During use, this module group can continuously and effectively absorb broadband noise in the environment, especially significantly suppressing unpleasant low-frequency booming. If the wall layout needs to be changed, simply overcome the magnetic force to remove the module by hand; the operation is simple and causes zero damage to the wall.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
