Referring to fig. 1-3, an embodiment of the present application provides a wall decoration layer 100 for sound insulation, which includes a housing 10, a first concave surface 11 and a second concave surface 12, wherein the second concave surface 12 is located in the first concave surface 11 along a projection perpendicular to the housing 10; the sound absorbing layer 20 comprises a base plate 21 and a sound insulating plate 22 arranged on the base plate 21, the base plate 21 is provided with a first surface and a second surface which are oppositely arranged, the first surface is attached to the first concave surface 11, and the second surface is attached to the sound insulating plate 22; the fixing layer 30 is provided with an opening, the sound insulation plate 22 is embedded in the opening, and the fixing layer 30 is attached to the second surface of the substrate 21.

Specifically, the housing 10 in this feature is an outer structure of the wall decoration layer, and the thickness of the decoration layer is increased by the design including the first concave surface 11 and the second concave surface 12. Since the second concave surface 12 is located in the first concave surface 11, the housing 10 forms a cavity, providing more sound insulation space for sound insulation. The increased thickness and the sound insulation space help to improve the sound insulation effect of the decorative layer. Further, the sound absorbing layer 20 is a key component of the decorative layer, and an effective sound insulation effect is achieved by the structure including the base plate 21 and the sound insulation plate 22. The first surface is attached to the first concave surface 11, and the second surface is attached to the sound insulation plate 22, so that the sound absorption layer 20 is firmly fixed in the housing 10. The combination of the base plate 21 and the soundproof plate 22 enables the decorative layer to absorb and eliminate the sound conducted by the wall surface, improving the soundproof effect.

Still further, the fixing layer 30 functions to fix the sound absorbing layer 20 in the decorative layer. By providing the opening, the sound insulation plate 22 can be fitted into the opening of the fixing layer 30, thereby fixing the sound absorption layer 20 in the decorative layer. The fixing layer 30 is attached to the second surface of the substrate 21, and ensures the sound absorbing layer 20 to be firmly fixed, so that the decorative layer is integrated, and the loosening of the internal material of the decorative layer and the generation of noise are effectively prevented.

In summary, the wall decoration layer convenient for sound insulation is suitable for various indoor places needing sound insulation effect, such as rooms, meeting rooms, recording studio, hotels and the like. The wall decoration device can effectively isolate the interference of external noise while decorating the wall surface, and provides a quiet and comfortable environment. Is especially suitable for places with high requirements on privacy and quiet environment, such as research rooms, libraries and the like. In addition, because of its thinner thickness, it is also suitable for those places where space is limited. In general, the wall decoration layer convenient for sound insulation provides decoration and simultaneously creates better living and working environment for people.

In one embodiment, the housing 10 is a synthetic resin.

In particular, synthetic resins generally have a higher density and hardness, which makes the wall decoration layer more rigid and durable on the surface, capable of resisting a certain degree of external force and impact, improving the durability and service life of the decoration layer. And the high density characteristic of the synthetic resin helps to reduce the propagation of sound, so that the decorative layer has a sound-insulating function to some extent. Further, the synthetic resin generally has excellent corrosion resistance, and can resist corrosion of environmental conditions such as humidity, acid and alkali, etc., so that the wall decoration layer can still keep stable and beautiful under humid or severe environments.

In a specific embodiment, the sound insulation surface is provided with a plurality of grooves for absorbing sound waves.

Specifically, by providing a plurality of grooves, the surface area of the sound-deadening surface is increased as compared with a flat surface. By the aid of the method, the decorative layer can be fully contacted with sound waves, the sound absorption area is increased, and accordingly the sound wave absorption capacity of the decorative layer is improved. The shape and structural design of the grooves can lead to multiple reflection and refraction of sound waves in the grooves, and the propagation path of the sound waves in the decorative layer is increased. The multiple reflections and refractions cause the energy of the sound wave to be gradually converted into heat energy, so that the absorption and dissipation of the sound wave are realized, the reflection and conduction of the sound wave are reduced, and the sound insulation effect is improved.

Further, the design of the grooves can effectively destroy the continuous propagation path of sound waves, prevent the reflection and conduction of the sound waves and reduce the propagation of noise in the decorative layer. This effectively prevents noise from being spread, thereby providing a better sound insulation effect and creating a quieter indoor environment.

In a specific embodiment, the sound insulation surface is a sound insulation sponge.

Specifically, the open cell structure of the sound-insulating sponge imparts excellent sound-absorbing properties. When sound waves enter the sponge, multiple reflection and refraction can occur between tiny bubbles, so that the sound wave energy is converted into heat energy, the absorption and dissipation of the sound waves are realized, the reflection and conduction of the sound waves are reduced, and the sound insulation effect is improved.

Further, the sound insulation sponge is usually made of a light foam material, so that the overload of the wall decoration layer is not increased, the building structure is not obviously influenced, and the sound insulation sponge is suitable for various walls. The sound insulation sponge also has good plasticity and workability, and can be sheared, cut, molded and the like to be processed into the required size and shape according to the requirements, so that different types of decorative layers can be manufactured conveniently.

In a specific embodiment, the fixing surface and the sound absorbing surface are integrally formed.

Specifically, as the fixing surface and the sound absorbing surface are integrally formed, no seam or joint exists between the fixing surface and the sound absorbing surface, the sound insulating layer forms an integral structure inside the decorative layer, and the stability and the durability of the decorative layer are improved. And the integrated into one piece's design has guaranteed the closely laminating between sound absorbing surface and the fixed surface, has avoided because the space that seam or junction led to, has ensured the effective sound absorbing performance of puigging. The sound wave is difficult to penetrate through the tightly attached structure, so that a better sound insulation effect is achieved. The fixing surface and the sound absorbing surface are integrally formed, so that the manufacturing process can be simplified, the production links are reduced, and the production efficiency is improved. Meanwhile, the waste of materials is reduced, and the cost is saved.

In a specific embodiment, after the second surface of the fixing surface is attached to the first concave surface 11, an isolation layer is formed around the second concave surface 12, and the isolation layer is used for isolating sound waves.

Specifically, the isolation layer formed after the second surface of the sound-insulating layer is attached to the first concave surface 11 can effectively isolate the propagation of the acoustic wave. The sound wave in the sound insulation layer is blocked in the isolation layer, and reflection and conduction of the sound wave are reduced, so that the sound insulation effect of the decorative layer is enhanced. The presence of the barrier layer helps to prevent acoustic waves from forming resonances inside the decorative layer. Resonance means that sound waves resonate with the structural frequency of the decorative layer under certain conditions, resulting in amplification and distortion of the sound. The isolation layer is used as a buffer layer, can block resonance phenomenon and improve the acoustic performance of the decorative layer.

Further, the barrier layer surrounds the second concave surface 12, forming a complete sound-insulating layer structure. The design increases the stability of the inside of the decorative layer, avoids loosening or deformation of the sound insulation layer due to the influence of external force, and maintains the long-term stability and the sound insulation effect of the decorative layer. The structure of the sound insulation layer is designed, so that a complete isolation layer can be formed around the second concave surface 12 after the second surface of the fixing surface is attached to the first concave surface 11.

The second surface of the fixing surface is attached to the first concave surface 11 of the shell 10, so that the isolation layer is ensured to form a stable structure, and the propagation of sound waves is effectively isolated.

In summary, the design of forming the isolation layer is enclosed with the second concave surface 12 after the second surface of the fixing surface is attached to the first concave surface 11, so that the sound insulation effect and stability of the wall decoration layer are enhanced, better acoustic performance and use experience are provided, and a quieter and comfortable indoor environment is created.

In one embodiment, the fixing layer 30 is an aluminum alloy.

In particular, aluminum alloy is a lightweight material having a low density relative to conventional materials such as steel and the like, and thus the weight of the decorative layer is relatively light. Meanwhile, the aluminum alloy has excellent strength and corrosion resistance, so that the decorative layer has better deformation resistance and corrosion resistance. The aluminum alloy has good plasticity and workability, and can be conveniently subjected to the processing procedures of shearing, bending, welding and the like, so that the fixing layer 30 with various shapes and sizes can be conveniently manufactured, and different decoration requirements can be met. Further, the surface of the aluminum alloy can be subjected to surface treatment by oxidation, spraying and the like, so that the aluminum alloy has good appearance and durability. The aluminum alloy is used as the fixing layer 30 for the decorative layer to have more beautiful appearance and maintain good decorative effect for a long period of time.

In a specific embodiment, four elastic blocks 40 are disposed between the fixing layer 30 and the housing 10, and the four elastic blocks 40 are respectively disposed at four corners of the fixing layer 30 for damping vibration.

Specifically, the presence of the elastic block 40 can absorb and disperse external energy caused by vibration or vibration, thereby reducing conduction and reflection of sound. This helps to damp the propagation of sound waves inside the decorative layer, providing a better sound insulation effect. Further, the arrangement of the elastic block 40 inside the decoration layer can reduce the direct contact between the decoration layer and the housing 10, and avoid the occurrence of resonance phenomenon. Resonance refers to a phenomenon in which the decorative layer resonates with the case 10 under certain conditions, resulting in amplification and distortion of sound waves. The elastic block 40 serves as a buffer layer, and can effectively prevent resonance.

Still further, the elastic block 40 forms a kind of buffer layer between the decorative layer and the housing 10, increasing the stability inside the decorative layer. They can absorb external impact and vibration, so that the sound insulation layer of the decorative layer is kept in a stable state and is not easy to be influenced by external force. The design of being equipped with four elastic blocks 40 between fixed layer 30 and the casing 10 has increased the function of damping vibrations for the wall decorative layer of being convenient for give sound insulation, has provided better sound insulation effect and decorative layer's stability.

In one embodiment, the elastic block 40 is welded and fixed to the fixing layer 30.

Specifically, welding is a strong attachment means that can firmly secure the elastomeric block 40 to the securing layer 30. Such a connection can prevent the elastic block 40 from falling off or loosening due to external forces such as vibration, impact, etc., and maintain the long-term stability and sound insulation effect of the decorative layer.

Further, the elastic block 40 is tightly combined with the fixing layer 30 by welding to form a unitary structure. This fixing method can improve the damping effect of the elastic block 40, absorb and disperse the energy of external vibration and vibration, reduce the conduction and reflection of sound waves, and further enhance the sound insulation effect.

In a specific embodiment, the housing 10, the sound absorbing layer 20 and the fixing layer 30 are glued.

Specifically, the bonding connection mode can tightly bond the shell 10, the sound absorbing layer 20 and the fixing layer 30 together to form an integral structure, so that each component part of the wall decoration layer is tightly fixed, looseness and falling off are not easy to generate, and a stable decoration effect is provided. The glued joint may also form a bond without significant gaps between the housing 10, the sound absorbing layer 20 and the fixing layer 30, reducing the conduction and reflection of sound waves inside the decorative layer, further enhancing the sound insulation effect. The mode of gluing connection can also effectively reduce the air gap between different materials to reduce the permeability of sound wave, improve wall decorative layer's sound insulation performance. The shell 10, the sound absorbing layer 20 and the fixing layer 30 are in glued connection, so that the wall decoration layer convenient for sound insulation is added with the characteristics of firmness, no obvious gap and high sound insulation performance.

While the application has been described with respect to the above embodiments, it should be noted that modifications can be made by those skilled in the art without departing from the inventive concept, and these are all within the scope of the application.
