[0035] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0036] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0037] Unless otherwise specified or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0038] It should be noted that when a component is considered "fixed" to another component, it can be directly fixed to the other component or there can be an intervening component; when a component is considered "connected" to another component, it can be directly connected to the other component or there can be an intervening component; when a component is considered "mounted" on another component, it can be directly mounted on the other component or there can be an intervening component; when a component is considered "placed" on another component, it can be directly placed on the other component or there can be an intervening component.

[0039] This utility model proposes a sound absorption and diffusion conversion device 100, such as Figures 1 to 7As shown, the device includes a supporting body 1 and a rotating body 2. The supporting body 1 has a first sound-absorbing surface 11 and a first diffusion surface 21, which are disposed on the same side of the supporting body 1. The rotating body 2 has a second sound-absorbing surface 12 and a second diffusion surface 22, which are disposed on the front and back surfaces of the rotating body 2, respectively. The rotating body 2 is rotatably disposed on the supporting body 1, and the rotation point of the rotating body 2 on the supporting body 1 is disposed between the first sound-absorbing surface 11 and the first diffusion surface 21. The rotating body 2 has a first moving position and a second moving position. In the first moving position, the first sound-absorbing surface 11 and the second sound-absorbing surface 12 are located on the same side of the supporting body 1, forming a sound-absorbing display surface 101. In the second moving position, the first diffusion surface 21 and the second diffusion surface 22 are located on the same side of the supporting body 1, forming a diffusion display surface 102.

[0040] Specifically, the first sound-absorbing surface 11 and the first diffusion surface 21 are disposed on the same side of the supporting body 1, and the second sound-absorbing surface 12 and the second diffusion surface 22 are disposed on the front and back surfaces of the rotating body 2, respectively. Furthermore, the rotating body 2 is rotatably disposed on the supporting body 1, and the rotation point of the rotating body 2 on the supporting body 1 is located between the first sound-absorbing surface 11 and the first diffusion surface 21. Therefore, the rotating body 2 can rotate and move on the supporting body 1. When the rotating body 2 moves to the first moving position, the first sound-absorbing surface 11 and the second sound-absorbing surface 12 are located on the same side of the supporting body 1, forming a sound-absorbing display surface 101. This sound-absorbing display surface 101 is used for sound absorption. Placing the sound-absorbing diffusion conversion device 100 in the multi-functional hall can prevent the sound from the multi-functional hall from propagating outdoors. When the rotating body 2 moves to the second moving position, the first diffusion surface 21 and the second diffusion surface 22 are located on the same side of the supporting body 1, forming a diffusion display surface 102. The diffusion display surface 102 is used for sound propagation in the multi-functional hall. The diffusion treatment can also avoid the generation of sound quality defects such as sound focusing and echo.

[0041] Furthermore, when using the sound absorption and diffusion conversion device 100, simply adjusting the position of the rotating body 2 allows the sound absorption and diffusion conversion device 100 to switch between sound absorption and diffusion. Its operation is simple and convenient. Moreover, the sound absorption and diffusion of the sound absorption and diffusion conversion device 100 are integrated into one unit, eliminating the need to assemble the sound absorption surface and the diffusion surface separately. This solves the problem that the assembly of existing separately designed sound absorption walls and diffusion walls is relatively labor-intensive.

[0042] Preferably, the areas of the first sound-absorbing surface 11, the second sound-absorbing surface 12, the first diffusion surface 21, and the second diffusion surface 22 are all equal; in the first moving position, the first diffusion surface 21 and the second diffusion surface 22 are in contact, and both the first diffusion surface 21 and the second diffusion surface 22 are hidden between the rotating body 2 and the supporting body 1; in the second moving position, the first sound-absorbing surface 11 and the second sound-absorbing surface 12 are in contact, and both the first sound-absorbing surface 11 and the second sound-absorbing surface 12 are hidden between the rotating body 2 and the supporting body 1.

[0043] Specifically, since the areas of the first sound-absorbing surface 11, the second sound-absorbing surface 12, the first diffusion surface 21, and the second diffusion surface 22 are all equal, when the rotating body 2 is in the first moving position, the first sound-absorbing surface 11 and the second sound-absorbing surface 12 form a sound-absorbing display surface 101, while the first diffusion surface 21 and the second diffusion surface 22 are in contact, and both the first diffusion surface 21 and the second diffusion surface 22 are hidden between the rotating body 2 and the supporting body 1. By hiding the first diffusion surface 21 and the second diffusion surface 22, the sound absorption and diffusion conversion device 100 has a sound absorption effect, while avoiding the diffusion surface from affecting its sound absorption effect. When the rotating body 2 is in the second moving position, the first diffusion surface 21 and the second diffusion surface 22 form a diffusion display surface 102, while the first sound-absorbing surface 11 and the second sound-absorbing surface 12 are in contact, and both the first sound-absorbing surface 11 and the second sound-absorbing surface 12 are hidden between the rotating body 2 and the supporting body 1. By hiding the first sound-absorbing surface 11 and the second sound-absorbing surface 12, the sound absorption diffusion conversion device 100 has a diffusion effect, while avoiding the sound-absorbing surface from affecting its diffusion effect.

[0044] Preferably, in the first moving position, the first sound-absorbing surface 11 and the second sound-absorbing surface 12 of the rotating body 2 are located on the same plane; in the second moving position, there is a height difference between the first diffusion surface 21 and the second diffusion surface 22. Specifically, since there is a height difference between the first diffusion surface 21 and the second diffusion surface 22 in the second moving position, when the rotating body 2 is in the first moving position, both the first sound-absorbing surface 11 and the second sound-absorbing surface 12 are located on the same horizontal plane.

[0045] Preferably, both the first sound-absorbing surface 11 and the second sound-absorbing surface 12 are made of sound-absorbing cotton; the first diffusion surface 21 and the second diffusion surface 22 have multiple spaced grooves 23. Specifically, the sound-absorbing cotton is a man-made inorganic fiber. It is made from natural minerals such as quartz sand, limestone, and dolomite as the main raw materials, combined with some chemical raw materials such as soda ash and borax to form glass. In the molten state, it is blown into flocculent fine fibers by external force. The fibers are three-dimensionally intertwined and entangled with each other, presenting many small gaps. It replaces sponges and is used in sound-absorbing soft padding in entertainment venues such as KTVs, cinemas, dance halls, and multi-functional halls. The first diffusion surface 21 and the second diffusion surface 22 have multiple spaced grooves 23. After the sound enters the groove 23, the structure of the groove 23 changes the reflective surface of the wall, causing the sound wave to undergo diffuse reflection during propagation. This design can disperse the sound wave to different directions, avoiding echo interference caused by a single reflection direction, thereby improving the sound diffusion effect.

[0046] Preferably, both the first diffusion surface 21 and the second diffusion surface 22 are concave-convex in shape. When the rotating body 2 is in the first moving position, the concave surface 202 of the first diffusion surface 21 engages with the convex surface 201 of the second diffusion surface 22, and the convex surface 201 of the first diffusion surface 21 engages with the concave surface 202 of the second diffusion surface 22. Specifically, when the rotating body 2 is in the first moving position, the concave-convex surfaces of the first diffusion surface 21 and the second diffusion surface 22 are in contact, which improves the fit between the first diffusion surface 21 and the second diffusion surface 22. Furthermore, the engagement of the concave-convex surfaces of the first diffusion surface 21 and the second diffusion surface 22 also improves the stability of the first diffusion surface 21 and the second diffusion surface 22 after they are in contact, thereby improving the stability of the sound-absorbing display surface 101.

[0047] Preferably, the sound absorption and diffusion conversion device 100 further includes at least two hinge structures 3. The upper end of the rotating body 2 is rotatably connected to the upper end of the supporting body 1 through one of the hinge structures 3, and the lower end of the rotating body 2 is rotatably connected to the lower end of the supporting body 1 through the other hinge structure 3. Specifically, the upper and lower ends of the rotating body 2 are rotatably connected to the upper and lower ends of the supporting body 1 through the hinge structures 3, thereby improving the stability of the rotating body 2 rotating on the supporting body 1. In this embodiment, the hinge structures 3 can be purchased commercially.

[0048] Preferably, the sound absorption and diffusion conversion device 100 further includes a support frame 4, with the support body 1 suspended on the support frame 4. The support frame 4 is located at the front end of the support body 1 and within the shadow area of ​​the support body 1. Specifically, when the support body 1 is suspended on the support frame 4 and the support frame 4 is within the shadow area of ​​the support body 1, and the support body 1 is placed indoors near a wall, the support body 1 can completely cover the support frame 4, thus concealing the support frame 4 and improving the aesthetic appearance of the sound absorption and diffusion conversion device 100.

[0049] Preferably, the support frame 4 includes a support plate 41, a first support block 45, and a second support block 46. The first support block 45 is mounted on the support plate 41, and both the first support block 45 and the second support block 46 have a first slot 451. The support body 1 has a first suspension plate 13 and a second suspension plate 14, both of which have barbs 131 that engage with the first slot 451. Specifically, the support plate 41 supports the first support block 45 and the second support block 46, which are arranged vertically. The first suspension plate 13 of the support body 1 corresponds to the first support block 45, and the second suspension plate 14 corresponds to the second support block 46. By engaging the barbs 131 with the first slot 451, the first suspension plate 13 is suspended on the first support block 45, and the second suspension plate 14 is suspended on the second support block 46, thus enabling the support body 1 and the support frame 4 to be detachably assembled.

[0050] Preferably, the end of the first support block 45 is inclined, and a first groove 451 is formed between the side wall of the first support block 45 and the support plate 41; the end of the first suspension plate 13 is inclined, and a second groove 132 is formed between the side wall of the first suspension plate 13 and the support body 1; at least a portion of the first support block 45 is engaged in the second groove 132, and at least a portion of the first suspension plate 13 is engaged in the first groove 451. Specifically, as shown... Figure 6 and Figure 7 As shown, during installation, simply align the first suspension plate 13 with the first support block 45, and the second suspension plate 14 with the second support block 46, with the first suspension plate 13 abutting against the first support block 45 and the second suspension plate 14 abutting against the second support block 46. During disassembly, simply move the support body 1 upwards, causing the first suspension plate 13 and the second suspension plate 14 to disengage from the first slot 451, and the first support block 45 and the second support block 46 to disengage from the second slot 132, thus completing the disassembly.

[0051] Preferably, the support frame 4 further includes a folded edge 42, a first support beam 43, and a second support beam 44. The folded edge 42 is installed on the outer edge of the support plate 41. The first support beam 43 and the second support beam 44 are both installed on the support plate 41, and both the first support beam 43 and the second support beam 44 are located inside the folded edge 42, and the first support beam 43 and the second support beam 44 are arranged perpendicularly. Specifically, the two ends of the first support beam 43 and the second support beam 44 are fixed to the folded edge 42, and the folded edge 42 is fixed to the outer edge of the support plate 41. The first support beam 43 and the second support beam 44 are used to improve the stability of the support frame 4, so that the support body 1 is stably suspended on the support frame 4.
