Description

Technical Field

[0001] The invention relates to the field of building decoration, and in particular to a hollow decorative facing with a sound-absorbing function. Background Art

[0002] In some performance venues, such as theaters and concert halls, the sound is easy to reverberate in an open environment, which can seriously affect the clarity of the language and the sound quality. In order to ensure the clarity of the language and the sound quality, it is often necessary to do sound absorption treatment in the venue to control the reverberation time. Usually, sound absorption treatment is performed on the back wall, side wall and local area.

[0003] Most of the existing sound-absorbing materials are loose and porous materials, such as the common sound-absorbing cotton. However, in the existing technology, the sound-absorbing measures are generally constructed before the theaters, concert halls and other places are put into use, and generally cannot be adjusted after the construction is completed.

[0004] However, due to the differences in live performance forms, sound effects and other factors, the sound absorption effects that can be achieved are also different. The stronger the sound absorption effect is, the better. Sometimes it is necessary to retain a certain reverberation time to ensure the fullness of the sound quality, and sometimes it is necessary to reduce the reverberation as much as possible. However, the existing sound absorption measures cannot be adjusted once the construction is completed. Therefore, they cannot meet different needs when used on-site, especially for some performances with high requirements for sound quality. The experience will be greatly reduced.

[0027] The technical solution of the present invention is further described below in conjunction with specific embodiments:

[0028] A hollow decorative facing with a sound-absorbing function comprises a hollow facing layer 1, a sound-absorbing backing 2, and an adjustable sound-absorbing module. The sound-absorbing backing 2 is installed on the back of the hollow facing layer 1 and covers the back of the hollow facing layer 1. The sound-absorbing backing 2 is such as black glass fiber cloth. The adjustable sound-absorbing module comprises a plurality of parallel sound-absorbing panels 3. The plurality of sound-absorbing panels 3 are distributed up and down. A rotating shaft 4 is arranged along the length direction of the sound-absorbing panels 3. The rotating shafts 4 of the sound-absorbing panels 3 are transmission-connected with each other. During the rotation of the sound-absorbing panels 3 along the rotating shaft 4, the gaps between adjacent sound-absorbing panels 3 gradually increase or decrease.

[0029] Specifically, the hollow facing layer 1 includes a facing frame 11 and a hollow facing 12 installed in the facing frame 11, wherein the hollow facing 12 forms a facing that is concave or convex relative to the facing frame 11; one side of the facing frame is hingedly installed on the front side of the frame of the adjustable sound-absorbing module through a hinge 5, and the hollow facing layer 1 can be flipped open relative to the frame 6, so as to facilitate the inspection and maintenance of the adjustable sound-absorbing module.

[0030] Hollow finishes such as GRC finishes, GRC, also known as Glass Fiber Reinforced Concrete, have good plasticity and can be shaped through molds. They are light in weight and high in strength, making it easy to create hollow forms.

[0031] The adjustable sound absorbing module also includes a frame 6 installed outside the sound absorbing panel 3. The sound absorbing panel 3 is movably installed in the frame 6 through the rotating shaft 4. The rotating shafts 4 of the sound absorbing panel 3 are connected by a transmission belt 7, and can also be transmitted by gears, chains, etc. In this embodiment, the transmission belt 7 is preferably used for transmission. The transmission belt 7 is light in weight, has low transmission noise, and is easy to replace.

[0032] In order to facilitate the rotation of the sound absorbing panels 3 , a rotation shaft 4 of one of the sound absorbing panels 3 is connected to a driving device for driving the sound absorbing panel 3 to rotate along the rotation shaft 4 , and the driving device is manually driven or electrically driven.

[0033] In one embodiment, the driving device can be a rotating handle, and when rotation is required, the hollow finishing layer can be opened and the rotating handle can be rotated; in one embodiment, the driving device can also be a driving mechanism with a motor, which is connected to the rotating shaft through a motor connected to a speed change gear box, and the rotation of the motor is controlled by manual control, remote control, etc.

[0034] The sound absorbing board 3 includes a back plate 31 and a sound absorbing layer 32. The sound absorbing layer 2 is such as sound absorbing cotton. The back plate 31 is provided with an installation groove for installing the sound absorbing layer 32. The sound absorbing layer 32 is removably embedded in the installation groove and can be replaced as needed.

[0035] The hollow decorative facing with sound absorption function of the present invention is embedded in the building wall, so the hollow decorative facing with sound absorption function of the present invention can be processed in the factory stage and assembled and installed on site.

[0036] Since it is embedded in the building wall, a slot needs to be reserved or opened in the building wall. After installation, there may be a gap between the frame 6 and the edge of the slot, which may need to be filled. Therefore, as a preference, the edge of the frame 6 is also provided with a decorative folded edge 61. When the frame 6 is embedded in the building wall, the decorative folded edge 61 is set in contact with the building wall, and the edge of the slot is covered by the decorative folded edge 61 to ensure the aesthetics after installation.

[0037] When in use, if it is necessary to enhance the sound absorption effect, the sound absorbing panels 3 are rotated to reduce the gap between adjacent sound absorbing panels 3 so that the edges of the sound absorbing panels overlap each other. Figure 3 If you need to weaken the attraction effect to retain a certain reverberation, the sound-absorbing panels 3 are rotated to increase the gap between adjacent sound-absorbing panels 3, such as Figure 4 shown.

[0038] This embodiment is only a further explanation of the present invention, not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it will be protected by the patent law.
