Description

Technical Field

[0001] This utility model relates to the field of building sound-absorbing materials technology, and more specifically to a 3D sound-absorbing decorative brick. Background Technology

[0002] In architectural acoustics and noise control engineering, sound absorption is a key means of reducing reverberation and lowering noise levels. Currently, various sound-absorbing materials and structures exist on the market. For example, Chinese patent CN214006334U discloses a composite sound-absorbing panel and decorative structure. This composite sound-absorbing panel consists of a perforated plate and a sound absorber made of particulate sound-absorbing material. The perforated plate has a receiving groove in which the sound absorber is placed. While this structure has some effect in noise reduction and has advantages such as high strength, small thickness, low material consumption, and protection of the sound absorber from damage, it still has significant shortcomings. It requires an additional shell, resulting in a complex overall structure. This not only increases the complexity of the production process but also raises production costs and reduces production efficiency, making it difficult to meet the market demand for efficient and low-cost sound-absorbing materials. Therefore, it is necessary to further improve and optimize existing sound-absorbing material structures. Summary of the Invention

[0003] The purpose of this utility model is to provide a stable, reliable, easy-to-manufacture, and high-quality 3D sound-absorbing decorative brick with microparticles to overcome the shortcomings of existing technologies.

[0004] The present invention achieves the above-mentioned objective by adopting the following technical solution: a microparticle 3D sound-absorbing decorative brick, characterized in that it includes a microparticle sound-absorbing body, the microparticle sound-absorbing body is provided with multiple layers of annular borders, the inner diameter of the multiple layers of annular borders decreases from top to bottom, forming a stepped inner wall structure.

[0005] As a further explanation of the above scheme, a sound-absorbing cavity is set in the middle of the particulate sound-absorbing body. As the core area of ​​sound absorption, the sound-absorbing cavity provides spatial conditions for the absorption and attenuation of sound waves. After the sound waves enter the sound-absorbing cavity, they come into full contact with the inner wall of the cavity and the particulate sound-absorbing material inside, and the sound waves are effectively absorbed through friction, vibration and other effects.

[0006] Furthermore, the particulate sound-absorbing body is provided with a front opening and a rear opening corresponding to the sound-absorbing cavity, so that sound waves can smoothly enter the sound-absorbing cavity and ensure the continuity of the sound absorption process.

[0007] Furthermore, the first step of the stepped inner wall structure has a width of 8-9mm and a height of 14-16mm. This size setting facilitates splicing with other decorative bricks, ensuring the flatness and tightness of the spliced ​​parts, while also meeting the requirements of structural strength and sound absorption performance. The steps below the second layer have a width of 13-15mm and a height of 14-16mm. The reasonable size difference allows the stepped inner wall structure to better reflect and absorb sound waves while ensuring overall strength.

[0008] Furthermore, the stepped inner wall structure has three or more steps. By increasing the number of steps, the number of times sound waves are reflected and absorbed inside the decorative brick can be increased, and the propagation path of sound waves inside the decorative brick can be extended, thereby improving the sound absorption efficiency and meeting the sound absorption performance requirements of different places.

[0009] Furthermore, the particulate sound-absorbing body is an integrated structure. It is made by mixing particulate sound-absorbing materials evenly according to a certain ratio, injecting them into a mold, and then demolding the particulate sound-absorbing decorative brick after the material cools and solidifies. This integrated manufacturing method simplifies the production process, reduces assembly steps, lowers production costs, and at the same time ensures the integrity and stability of the decorative brick structure.

[0010] Furthermore, the particulate sound-absorbing body is installed by pasting or nailing, and multiple particulate sound-absorbing bodies are assembled into a whole.

[0011] The beneficial effects that this utility model can achieve by adopting the above-mentioned technical solution are:

[0012] 1. This utility model adopts an integrated microparticle sound-absorbing body, which simplifies the production process, reduces production links and material costs, improves production efficiency, and has obvious cost advantages; the unique stepped inner wall structure and sound-absorbing cavity design provide good space and conditions for sound wave absorption and attenuation, enabling sound waves to be reflected and absorbed multiple times inside the decorative brick, greatly improving sound absorption efficiency, effectively reducing noise level, and meeting the sound absorption and noise reduction needs of various building spaces.

[0013] 2. Easy installation and strong applicability: The particle sound-absorbing body can be installed by pasting or nailing, which is flexible and suitable for different building walls and ceilings; multiple decorative bricks can be easily assembled into a whole, and can be flexibly combined according to the actual decoration area and shape to meet diverse decoration needs.

[0014] 3. Excellent splicing effect: The reasonable step size design allows the decorative bricks to be spliced ​​tightly, ensuring the flatness and tightness of the spliced ​​bricks. This not only enhances the aesthetics of the overall decorative effect, but also reduces sound wave leakage caused by splicing gaps, further improving the sound absorption performance.

Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in this description of the utility model, "at least" means one or more, unless otherwise explicitly specified.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components.

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings, making the technical solution and beneficial effects of this utility model clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] like Figures 1-2 As shown, this utility model is a microparticle 3D sound-absorbing decorative brick, including a microparticle sound-absorbing body 1. The microparticle sound-absorbing body 1 is provided with multiple layers of annular frames 1-1, the inner diameter of which decreases sequentially from top to bottom, forming a stepped inner wall structure. A sound-absorbing cavity 1-2 is provided in the middle of the microparticle sound-absorbing body. The sound-absorbing cavity serves as the core area for sound absorption in the entire decorative brick, creating spatial conditions for sound wave absorption and attenuation. When sound waves enter the sound-absorbing cavity, they can fully contact the inner wall of the cavity and the microparticle sound-absorbing material inside. Through physical actions such as friction and vibration, efficient absorption of sound waves is achieved, thereby achieving a good sound absorption and noise reduction effect. To ensure that sound waves can smoothly enter the sound-absorbing cavity and achieve continuity of the sound absorption process, the microparticle sound-absorbing body 1 is provided with a front opening 1-3 and a rear opening 1-4 corresponding to the sound-absorbing cavity 1-2. Sound waves can enter from the front opening. After being absorbed and attenuated by the sound-absorbing cavity, some of the unabsorbed sound waves can be transmitted from the rear opening and continue to be absorbed by other sound-absorbing materials or structures, or dissipate in the space.

[0024] In terms of size design, the particle sound-absorbing body measures 200mm long * 200mm wide * 75mm high. The first step of the stepped inner wall structure has a width of 8.5mm and a height of 15mm. This size design facilitates splicing with other decorative bricks, ensuring the flatness and tightness of the spliced ​​decorative surface for an aesthetically pleasing overall effect. Furthermore, it meets the requirements for structural strength and sound absorption performance, ensuring the stability and reliability of the decorative bricks during actual use. The steps below the second layer have a width of 14mm and a height of 15mm. This reasonable dimensional difference allows the stepped inner wall structure to reflect and absorb sound waves multiple times while maintaining overall strength, further enhancing the sound absorption effect. The stepped inner wall structure has four steps. By increasing the number of steps, the number of times sound waves are reflected and absorbed within the decorative brick increases, extending the sound wave propagation path within the decorative brick, thereby improving sound absorption efficiency and meeting the sound absorption performance requirements of different locations.

[0025] The particulate sound-absorbing body adopts an integrated structural design. Its manufacturing process involves uniformly mixing particulate sound-absorbing materials according to a specific ratio, injecting the mixture into a custom mold, and then demolding it after the material cools and solidifies to obtain the particulate sound-absorbing decorative brick. This integrated manufacturing method simplifies the production process, reduces assembly steps, lowers production costs, and also ensures the integrity and stability of the decorative brick structure. In terms of installation, the particulate sound-absorbing body can be installed by gluing or nailing. In practical applications, the appropriate installation method can be selected according to the specific installation environment and needs. Multiple particulate sound-absorbing bodies can be assembled into a whole to achieve a large-area sound-absorbing decorative effect. The particulate sound-absorbing material consists of a binder and sound-absorbing particles. The sound-absorbing particles are a mixture of aeolian sand, manufactured sand, slag, and natural sand particles. The binder accounts for 15%-45% of the mass of the sound-absorbing particles. These materials are readily available and inexpensive, and since they are common in this technical field, they will not be described in detail here.

[0026] During installation, if using an adhesive method: Clean the surface of the building wall where decorative tiles will be installed, ensuring it is flat, clean, and dry. Mark the installation positions of the decorative tiles on the wall or ceiling according to the decoration design requirements. Apply a dedicated construction adhesive evenly to the back of the decorative tile, then adhere the tile to the wall or ceiling according to the marked positions. Gently tap the tile with a rubber mallet to ensure a tight fit and secure adhesion. During the adhesion process, pay attention to adjusting the position and angle of the decorative tiles to ensure even and flat seams.

[0027] If using a nailing installation method: First, clean the installation surface and mark the installation positions. Place the decorative brick in the marked positions and use appropriate nails or screws to fix the decorative brick to the wall or ceiling through the pre-drilled nail holes (if not pre-drilled, these holes can be drilled before installation). During nailing, ensure that the nails or screws are driven in vertically and with moderate force to avoid damaging the decorative brick due to excessive force or resulting in an insecure fixation due to insufficient force. Install multiple decorative bricks sequentially according to the design plan to complete the overall sound-absorbing decoration project.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
