Description

Technical Field

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

[0002] Most traditional decorative paintings or ornaments on the market are made of paper, plastic, metal, glass, etc. While these traditional ornaments can beautify interior spaces through elements such as color, pattern, and shape, and to a certain extent satisfy people's needs for spatial visual effects, their functions are relatively simple and generally do not have the function of sound absorption and noise reduction. With the continuous improvement of the quality of life in modern society, people have put forward higher requirements for the sound environment quality of living, working, and various public activity places. In living spaces such as family living rooms and bedrooms, people hope to reduce external noise interference and create a quiet and comfortable resting atmosphere; in functional spaces such as conference rooms, recording studios, and classrooms, the requirements for sound clarity and purity are strict, and reverberation and echo need to be effectively controlled. For example, Chinese patent application number 202510340800.6 discloses an energy-saving decorative building panel, including a first energy-saving decorative panel, a second groove formed on one side of the second energy-saving decorative panel, a lamp tube and a support block fixed in the second groove, and a sleeve fixed on one side of the main body of the decorative painting, the sleeve being engaged and connected to the outside of the support block. This energy-saving decorative panel for buildings requires a sleeve to be clipped onto the outside of a support block during installation of the main decorative painting. The clips automatically engage with the mounting holes, locking the sleeve and securing the main decorative painting. The main painting can then function as a decoration, and the illuminated lights enhance its visual appeal. Before disassembling the main painting, two knobs are rotated, causing two lead screws to rotate and two first pistons to move to the right. Each rightward movement of the first pistons moves two second pistons downward. Once all four clips have moved down and disengaged from their mounting holes, the sleeve is unlocked, and the main decorative painting can then be removed. This patented design uses a complex structure of sleeves, clips, lead screws, and pistons to achieve the installation and disassembly of the main decorative painting. While it incorporates sound-absorbing cotton for some noise reduction, the overall complex structure increases production difficulty and cost, and makes operation cumbersome. Furthermore, this type of traditional decorative structure feels stiff, posing a safety hazard of scratches and bumps to children in environments with high child activity. Therefore, developing a decorative sound absorber that is simple in structure, easy to install, comfortable to the touch, and has good sound absorption effect has become the key to solving the functional defects of existing traditional decorative bodies. Summary of the Invention

[0003] The purpose of this utility model is to provide a decorative sound absorber that is easy to manufacture and process, comfortable to the touch, and has good sound absorption effect in order to overcome the shortcomings of the existing technology.

[0004] This utility model achieves the above-mentioned objectives using the following technical solution: a decorative sound absorber, characterized in that it comprises an inner sound-absorbing soft package and an outer sound-absorbing polyester body, the outer sound-absorbing polyester body having a cavity for accommodating the inner sound-absorbing soft package, the inner sound-absorbing soft package comprising sound-absorbing cotton and its outer covering fabric, which feels comfortable to the touch, unlike the hard feel of traditional decorative paintings, and in particular can prevent children from being scratched or bumped; it will not be at risk of breaking if dropped, nor will it damage any objects that come into contact with it, and its durability is higher than that of traditional decorative paintings.

[0005] As a further explanation of the above solution, an adhesive is provided on the back of the inner sound-absorbing soft package. The inner sound-absorbing soft package is embedded in the cavity of the outer sound-absorbing polyester body, and the back of the inner sound-absorbing soft package is glued and fixed to the bottom surface of the cavity of the outer sound-absorbing polyester body. During installation, the inner sound-absorbing soft package is embedded in the cavity of the outer sound-absorbing polyester body, and the back of the inner sound-absorbing soft package is glued and fixed to the bottom surface of the cavity of the outer sound-absorbing polyester body through the adhesive. This connection method is simple and reliable, and can ensure a stable bond between the inner sound-absorbing soft package and the outer sound-absorbing polyester body.

[0006] Furthermore, the shape of the inner sound-absorbing soft package is consistent with the cavity shape of the outer sound-absorbing polyester body, allowing the two to be integrated into one unit. Whether it is round, square, oval, or other special shapes, the matching of the two shapes can ensure that the decorative sound absorber looks neat and beautiful after installation, while also being conducive to the performance of sound absorption.

[0007] Furthermore, the sound-absorbing cotton is 40-60mm thick, and the fabric covers the front and sides of the sound-absorbing cotton. The thicker sound-absorbing cotton can effectively absorb sound of different frequencies and enhance the sound absorption effect of the decorative sound absorber.

[0008] Furthermore, the back of the external sound-absorbing polyester body adopts a metal clip embedded installation method. This installation method does not require precise positioning, the installation process is simple and quick, and the installation is firm and reliable after installation, which can meet the needs of different installation scenarios.

[0009] Furthermore, a fastener is provided on the back of the external sound-absorbing polyester body, and the fastener is movably provided with a buckle that engages with it.

[0010] Furthermore, the external sound-absorbing polyester body includes a base plate and a polyester fiber board arranged circumferentially along the base plate. The polyester fiber board itself is an excellent sound-absorbing and noise-reducing material. Applying it to the external sound-absorbing polyester body can work synergistically with the internal sound-absorbing soft package to further improve the overall sound absorption and noise reduction function of the decorative sound absorber.

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

The inner sound-absorbing soft pack is made of thick sound-absorbing cotton, with high-density fabric covering its front and perimeter, and adhesive glue on its back. The outer sound-absorbing polyester body wraps around the inner sound-absorbing soft pack, serving as a decorative element. Both the sound-absorbing cotton of the inner soft pack and the polyester fiberboard of the outer sound-absorbing polyester body have good sound absorption performance. The two work together to effectively absorb sounds of different frequencies, significantly improving the sound absorption and noise reduction effect of the decorative sound absorber and meeting people's needs for a good acoustic environment.

[0013] 2. The inner sound-absorbing soft padding uses a design of cloth-covered sound-absorbing cotton, making the decorative sound absorber feel soft and comfortable to the touch, unlike the stiff feel of traditional decorative paintings. At the same time, the soft material can prevent children from being scratched or bumped during contact. Even if the decorative sound absorber is accidentally dropped, it will not break or damage the objects it touches, greatly improving the safety and durability of the product.

[0014] 3. The metal clips on the back of the external sound-absorbing polyester body are embedded for easy and quick installation without the need for precise positioning. This reduces the difficulty and time cost of installation and makes it suitable for various architectural and decorative scenarios.

[0015] 4. The components of decorative sound absorbers have relatively simple structures, mature production processes, and readily available raw materials, which facilitates large-scale production and reduces production costs. Attached Figure Description
