Abstract
Description
Technical Field
[0001] This utility model relates to the field of acoustic diffusion plate technology, specifically an acoustic diffusion component based on a magnetic attraction structure. Background Technology
[0002] Concert halls are a very important type of performing arts architecture, and cities of all types have designed concert halls for citizens to enjoy and exchange ideas. Their biggest feature is that they require natural sound performances, which puts forward high requirements for the acoustic design of concert halls.
[0003] In concert halls, the sound source originates from the stage and travels through a reflector above it before reaching the audience area. This propagation pattern is highly effective in enhancing direct sound and improving musical clarity. Therefore, diffuser panels are installed on the walls to diffuse the sound from the stage, ensuring a full and even sound coverage of the entire audience area and providing clear sound for the audience. However, current diffuser panels are fixed to the walls with foam adhesive, making disassembly difficult and resulting in low reusability and high construction costs for concert halls. To address this, an acoustic diffusion component based on a magnetic structure is proposed. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide an acoustic diffusion component based on a magnetic attraction structure to solve the technical problems mentioned in the background.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an acoustic diffusion component based on a magnetic structure, comprising a diffusion plate body, multiple sets of the diffusion plate bodies being distributed in a rectangular array on a wall, and a positioning frame component connected to the wall being provided on the rear surface of the diffusion plate body;
[0006] The diffuser plate body includes a positioning plate connected to a positioning frame assembly. The front surface of the positioning plate is provided with a diffuser for diffusing sound waves. The positioning frame assembly includes a main frame that is fixed to the wall with expansion bolts. A stepped groove is fixed on the front surface of the main frame. The stepped groove and the main frame form a stepped groove for placing the positioning plate. A rectangular groove is reserved at the position where the positioning plate contacts the stepped groove. An embedded magnet is embedded in the outer wall of the rectangular groove to attract the connecting metal frame.
[0007] As a preferred technical solution, the positioning plate has sealing grooves on two adjacent sets of outer walls, and sealing strips are fixed on the two adjacent sets of outer walls. The sealing grooves and sealing strips are symmetrically arranged along the diagonal of the positioning plate.
[0008] As a preferred technical solution, the diffuser is provided with multiple sets of active handles in the transverse direction. Each set of active handles is rotatably connected to the main frame, and one end of the active handle extends to the outside of the main frame and is provided with an inner hexagonal groove.
[0009] As a preferred technical solution, an elastic sleeve is fixed to the side of the positioning plate near the main frame, and the elastic sleeve is sleeved on the outer wall of the active handle.
[0010] As a preferred technical solution, the outer wall of the active handle is fitted with a movable sleeve that can slide into the elastic kit, and the number of the movable sleeves corresponds to the positioning plate.
[0011] As a preferred technical solution, the outer wall of the movable sleeve is fixed with two sets of constraint ears, and a constraint rod is sleeved inside the constraint ears. Both ends of the constraint rod are fixedly installed on the main frame.
[0012] As a preferred technical solution, the outer diameter of the movable sleeve is smaller than the inner diameter of the elastic sleeve.
[0013] In summary, the present invention has the following main advantages:
[0014] This invention utilizes embedded magnets to first connect the diffuser plate body to the outer wall of the main frame, until it forms a wall on the concert hall wall. At this point, rotating the active handle can lock the diffuser plate body, allowing for convenient and efficient installation. Conversely, the diffuser plate body can be flexibly removed and reused later, thus saving on the construction cost of the concert hall. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0023] The embodiments of this utility model will be described below based on its overall structure.
[0024] An acoustic diffusion component based on a magnetic structure, such as Figures 1 to 5 As shown, it includes a diffuser plate body 100, and multiple diffuser plate bodies 100 are distributed in a rectangular array on the wall. The rear surface of the diffuser plate body 100 is provided with a positioning frame assembly 200 connected to the wall.
[0025] The diffuser plate body 100 includes a positioning plate 110 connected to the positioning frame assembly 200. The front surface of the positioning plate 110 is provided with a diffuser part 120 for diffuser sound waves. The positioning frame assembly 200 includes a main frame 220 fixed to the wall by expansion bolts. The front surface of the main frame 220 is fixed with a stepped groove 230. The stepped groove 230 and the main frame 220 form a stepped groove 230 for placing the positioning plate 110. A rectangular groove 130 is reserved at the position where the positioning plate 110 contacts the stepped groove 230. An embedded magnet 140 is embedded in the outer wall of the rectangular groove 130 and is attracted to the connecting metal frame 210. The number of embedded magnets 140 is multiple and they are distributed along the perimeter of the rectangular groove 130.
[0026] The positioning plate 110 has two adjacent sets of outer walls with sealing grooves 160 and two adjacent sets of outer walls with sealing strips 170. The sealing grooves 160 and sealing strips 170 are symmetrically arranged along the diagonal of the positioning plate 110.
[0027] Multiple sets of active handles 240 are provided laterally inside the diffuser 120. Each set of active handles 240 is rotatably connected to the main frame 220. One end of the active handle 240 extends to the outside of the main frame 220 and is provided with an inner hexagonal groove.
[0028] An elastic sleeve 150 is fixed to the side of the positioning plate 110 near the main frame 220, and the elastic sleeve 150 is sleeved on the outer wall of the active handle 240.
[0029] The outer wall of the active handle 240 is fitted with a movable sleeve 250 that can slide into the elastic kit 150, and the number of movable sleeves 250 corresponds to the positioning plate 110.
[0030] The outer wall of the active handle 240 is provided with an external thread at the position where it contacts the movable sleeve 250, and the movable sleeve 250 is provided with an internal thread that matches it.
[0031] As per the instruction manual Figure 1 As shown, the diffuser 120 is positioned away from the wall and facing outwards. The raised quadrilateral pyramid causes the sound rays propagating in the concert hall to be refracted, reflected, and scattered, changing the path of the sound and achieving the effect of incident sound diffusion. This makes the sound field more uniform and full, allowing the audience to clearly appreciate the music.
[0032] During installation, first fix the main frame 220 to the wall of the concert hall. Then, place the diffuser plate body 100 into each set of stepped grooves 230 one by one. The elastic sleeve 150 will fit onto the outer wall of the active handle 240. As the diffuser plate body 100 is fully inserted into the stepped groove 230, the embedded magnet 140 and the connecting metal frame 210 generate an adsorption force, so that the positioning plate 110 is stably fitted into the stepped groove 230, as shown in the instruction manual. Figure 1 As shown, the upper and lower and left and right adjacent positioning plates 110 are in a fitted state, while the sealing strip 170 enters the sealing groove 160 to eliminate the gap between the two adjacent sets of positioning plates 110, preventing the sound rays from passing through here, which can play a better role in the diffusion of sound rays in the concert hall, while preventing the positioning plates 110 from sliding and affecting the aesthetics and diffusion of sound rays.
[0033] Finally, the rotatable active handle 240 rotates within the main frame 220, while the movable sleeve 250, which is sleeved on the outer wall, slides along the axial direction of the active handle 240 and eventually enters the elastic kit 150, further increasing the stability between the fixed position plate 110 and the stepped groove 230. Similarly, the active handle 240 is rotated in the opposite direction later to slide the movable sleeve 250 out of the elastic kit 150, allowing each diffuser plate body 100 to be disassembled and reused.
[0034] Please refer to this carefully. Figure 2 , Figure 4 and Figure 5 Two sets of constraint ears 260 are fixed on the outer wall of the movable sleeve 250. A constraint rod 270 is fitted inside the constraint ear 260. Both ends of the constraint rod 270 are fixedly installed on the main frame 220.
[0035] The outer diameter of the movable sleeve 250 is smaller than the inner diameter of the elastic sleeve 150.
[0036] When the active handle 240 rotates, the constraint rod 270 restricts the movable sleeve 250 via the constraint ear 260, causing it to slide horizontally along its axis under the rotation of the active handle 240, so that the elastic sleeve 150 is sleeved on the outer wall of the active handle 240, thus conveniently fixing the diffuser plate body 100 to the main frame 220.
[0037] During installation, first fix the main frame 220 to the wall of the concert hall. Then, place the diffuser plate body 100 into each set of stepped grooves 230 one by one. The elastic sleeve 150 will fit onto the outer wall of the active handle 240. As the diffuser plate body 100 is fully inserted into the stepped groove 230, the embedded magnet 140 and the connecting metal frame 210 generate an adsorption force, so that the positioning plate 110 is stably fitted into the stepped groove 230, as shown in the instruction manual. Figure 1 As shown, the adjacent positioning plates 110 on the top, bottom, left, and right are in a fitted state, while the sealing strip 170 enters the sealing groove 160 to eliminate the gap between the two adjacent sets of positioning plates 110, preventing the sound rays from passing through here. This can play a better role in the diffusion of sound rays in the concert hall, while also preventing the positioning plates 110 from sliding and affecting the aesthetics and diffusion of sound rays. The parts not shown in this device are the same as or can be implemented using existing technology.
