Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications without inventive contribution to the present embodiment as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.

Example 1:

as shown in fig. 1 to 4, the present invention provides a modular sound-absorbing wall panel, which can be quickly laid according to the size of a wall surface, and due to the modular design, the laid area can be flexible and changeable, and can adapt to different shapes and sizes, and avoid obstacles on the wall surface. The modular sound absorption wall panel comprises a bottom plate 100 fixed on a wall body and a decorative piece 200 used for absorbing sound, wherein the decorative piece 200 is detachably connected with the bottom plate 100.

The decoration 200 is in a cover shape and has a decoration surface, and the middle of the decoration surface is recessed to form a first sound absorption cavity 300. The base plates 100 are triangular, rectangular or regular hexagonal, when a plurality of base plates 100 are spliced and tiled on a wall, the decorative surfaces between the decorative parts 200 on adjacent base plates 100 form a second sound-absorbing chamber 400 surrounding the first sound-absorbing chamber 300, and the second sound-absorbing chamber 400 is shown in detail in fig. 5 and 6.

In this embodiment, the bottom plate 100 is provided with a through hole 120 for connecting to a wall through a connecting member, which includes an expansion screw and a threaded fastener. When the base plate 100 is generally laid on a wall surface, an adhesive is applied between the base plate 100 and the wall surface, and the base plate 100 and the wall surface can be more firmly connected after the adhesive is solidified by fastening the base plate and the wall surface through the connecting piece.

Since the bottom plate 100 is to be tiled on a wall surface, the shape of the bottom plate 100 can be triangular, rectangular or regular hexagon, and these shapes can be seamless when tiled, and the present embodiment is described by taking the square bottom plate 100 as an example.

The decorative surface of the decorative member 200 is a curved surface. As shown in fig. 4, the decoration member 200 has an M-shaped section passing through the lower recess. Wherein, the farthest position of the decorative surface from the wall body is H1. The region of the decorative surface, which is at a distance of 0.9H1, H1 from the wall, surrounds the concave of the decorative surface. The farthest position of the decorative surface from the wall body is H1, the distance from the middle lower recess of the decorative surface to the wall body is H2, and H2 is less than or equal to (H1/2).

In all the cross sections of the decoration 200 passing through the lower recess, the position of the decoration surface farthest from the wall is taken as the origin of coordinates, the lower recess is taken as the terminal point, and if the line segment from the origin of the decoration surface to the terminal point is in accordance with the function F (x), and F (x) is the first derivative of the function F (x), F (x) is equal to or greater than x. Therefore, after the sound is reflected for multiple times on the decorative surface, the sound can be better absorbed, and the probability of being reflected back is reduced.

In this embodiment, the bottom plate 100 is provided with a hem 110 at a periphery thereof, and when the decoration 200 is connected to the bottom plate 100, the decoration 200 covers the bottom plate 100 and the hem 110 at a periphery thereof, and the hem 110 abuts against an inner wall of the decoration 200. The decorative piece 200 and the bottom plate 100 are detachably connected through the matching of the clamping groove 510 and the elastic buckle 520. Specifically, the locking groove 510 is disposed on the decoration 200, and the elastic buckle 520 is disposed on the base plate 100 (or the elastic buckle 520 is disposed on the decoration 200, and the locking groove 510 is disposed on the base plate 100).

Example 2:

as shown in fig. 7, the decoration 200 of the present embodiment is different from the decoration 200 of embodiment 1 in that: the decoration 200 in embodiment 2 has a double-layer structure, and the outer layer and the inner layer are hollow and fixed together through a connecting column. And a better sound insulation effect is realized through a double-layer structure. More specifically, the card slot 510 is provided at an outer layer of the decoration 200.

The rest of the structure is the same as that of embodiment 1, and detailed description is omitted.

Example 3:

as shown in fig. 8, the decoration 200 of the present embodiment is different from the decoration 200 of embodiment 2 in that: in the decoration member 200 of embodiment 2, the inner layer is provided with the circular hole at the lower recess in addition to the double-layer structure, so that the cavity between the outer layer and the inner layer, and the cavity between the inner layer and the bottom plate 100 are communicated. When the outer layer receives sound, vibration is generated, and because the inner cavity and the outer cavity are the same, the internal air pressure can be balanced, and a better sound insulation effect is realized.
