[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] Example 1

[0043] refer to Figures 1-11 A sound-absorbing and diffuser panel, comprising:

[0044] Base 3;

[0045] Multiple sets of sound-absorbing and diffusion panel bodies 1 are stacked and fixed on the base 3 in sequence.

[0046] Multiple lifting seats 4 are spaced apart on the same side of the lower end of the base 3 to adjust the height of the sound-absorbing diffuser plate;

[0047] Multiple movable wheels 6 are spaced apart on the other side of the lower end of the base 3 to adjust the position of the sound-absorbing diffuser plate.

[0048] This invention achieves a diffusion effect through a sound-absorbing and diffusion plate, sound-absorbing and diffusion components, rock wool, and a porous back plate, while also achieving a certain level of sound absorption performance. The two components can be used together, reducing installation and manufacturing costs.

[0049] In this embodiment, the base 3 includes two side-by-side base plates, and the lifting seat 4 is spaced apart on one of the base plates to facilitate height and position adjustment. The moving wheels 6 are spaced apart on the other base plate to facilitate dragging and arrangement.

[0050] Preferably, the caster wheel 6 is a swivel wheel.

[0051] Preferably, there are two sound-absorbing and diffusion plate bodies 1, and each of the two sound-absorbing and diffusion plate bodies 1 is stacked and fixed on the base 3 in sequence.

[0052] In this embodiment, the sound-absorbing diffuser plate body 1 includes:

[0053] Fixed frame 2, which has multiple fixed grids;

[0054] Multiple sound-absorbing and diffusing components are arranged on one side of the fixed frame 2 and are arranged one-to-one with multiple fixed grids. The sound-absorbing and diffusing components are fixed in the fixed grids.

[0055] The porous back plate 5 is connected to the other side of the fixed frame 2 away from the sound-absorbing and diffusing component.

[0056] Preferably, the fixed frame 2 has 4 fixed compartments.

[0057] Preferably, the multiple holes on the porous back plate 5 are arranged in a matrix.

[0058] This invention improves the stability of the overall structure by using a fixed frame.

[0059] In this embodiment, the sound-absorbing and diffusing component is circular or hexagonal in shape.

[0060] In this embodiment, the center of the sound-absorbing and diffusing component is set as a through hole, and the outer periphery of the through hole is provided with an irregular patterned surface.

[0061] In this embodiment, the fixing frame 2 is a square aluminum frame.

[0062] In practice, combining the fixed frame 2 with plastic material can improve the stability of the overall structure and further enhance the damping effect.

[0063] In practice, the rigidity of aluminum helps maintain the structural shape and reduces the transmission of vibrations, while the high damping properties of plastic can effectively absorb these vibrations.

[0064] In this embodiment, it also includes:

[0065] The first cotton cloth is placed on one side of the sound-absorbing and diffusing component and is pasted at the through hole;

[0066] Multiple pieces of primary rock wool are provided, each corresponding to a fixed grid, and are embedded within the fixed grid.

[0067] The second rock wool is set in accordance with the inner diameter of the fixing frame 2 and is located on the side of the first rock wool away from the first cotton cloth.

[0068] The second cotton cloth is placed between the second rock wool and the porous back plate 5 and fixed on the porous back plate 5.

[0069] The sound-absorbing and diffuser panel, which uses a plastic-aluminum-rock wool (hybrid design) structure, can precisely control the diffusion of sound waves, avoid excessive sound wave focusing or reflection, and improve the transparency and detail of the sound.

[0070] Rock wool has excellent sound absorption properties, especially in the mid-to-high frequency range, which helps to reduce standing waves and echoes, so that the sound waves do not sound muddy or blurry in the listening space, making the sound field more open and clear.

[0071] The damping properties of the plastic materials and aluminum metal structure effectively reduce excessive absorption of sound wave energy, maintaining the natural warmth of the sound and providing excellent detail reproduction.

[0072] The plasticity of plastic materials allows diffuser panels to be designed into more complex geometries, which not only helps with sound wave diffusion but also diversifies the visual effect of the space. For example, wave-shaped, honeycomb-shaped, or other geometric patterns can be designed, making the room not only acoustically excellent but also artistic.

[0073] This hybrid design can precisely adjust the frequency response of each frequency band, reduce excessive low-frequency resonance, and ensure the clarity of mid and high frequencies. Especially for HiFi / music listening spaces, this helps to more evenly reproduce every detail in the music.

[0074] The use of a hybrid design allows the diffuser to be presented in a variety of designs, with options for a wide range of colors, surface finishes (such as smooth / matte), and customizable shapes and textures. Compared to traditional wood styles, this design brings a more modern and technologically advanced visual effect.

[0075] Compared to wood, the hybrid design offers better durability and is less susceptible to moisture or warping, allowing the sound-absorbing diffuser to maintain stable performance in listening (HiFi or AV) spaces without requiring frequent maintenance.

[0076] The hybrid design is lightweight, making installation convenient and stable. Its structural flexibility allows it to adapt to different room sizes and acoustic requirements, enabling adjustments and customization to specific rooms.

[0077] The use of plastic materials and aluminum metal structures allows for diverse design options for the diffuser panels, including a variety of colors, surface finishes (such as smooth and matte), and customizable shapes and textures. Compared to the natural style of traditional wood, this material offers a more modern and technologically advanced visual effect, making it particularly suitable for modern HiFi interior design or home theater spaces.

[0078] In practice, complex geometric shapes are designed using CAD / CAM assistance and the application of DSS principles. Plastic is used as the main material to create a board that can both absorb and diffuse sound (sound-absorbing and diffused board), which also has greater aesthetic value.

[0079] In practice, rock wool, as an internal sound-absorbing material, can further enhance sound absorption and damping effects with its fiber structure, especially for mid-frequency (500-1kHz) and high-frequency (16k-20kHz) sound waves.

[0080] In this embodiment, the sound-absorbing and diffuser plate body 1 is made of plastic or composite material.

[0081] In this embodiment, the sound-absorbing and diffusing plate body 1 is provided with 2 sets.

[0082] In practice, plastics and composite materials typically have high damping coefficients, and their internal physical structure possesses natural energy loss characteristics, effectively absorbing and attenuating vibrations. This gives plastics an advantage in attenuating sound waves and reducing unnecessary vibrations when diffusing sound waves. The higher the damping coefficient, the better the material absorbs sound wave energy, and the less sound is reflected.

[0083] In practice, the diffusion effect of plastic materials can be adjusted by changing the formula (such as PC+ABS, or adding glass fiber) and the degree of diffusion. The high rigidity of aluminum helps maintain shape stability and provides stable acoustic performance. The internal rock wool provides excellent sound absorption and can effectively reduce mid-to-high frequency noise while maintaining low-frequency diffusion effect.

[0084] In practical implementation, the DSS theory, Dynamic Surface System, is invented. It combines non-parallel surfaces (irregular surfaces), non-parallel lines, irregular surface patterns, and irregular depths. Through CAD / CAM, complex geometric shapes and artistic patterns are precisely calculated. Moreover, by applying the DSS principle, there are almost no shape limitations, and very complex three-dimensional structures can be designed. Furthermore, the area can be maximized within the same range to achieve a better diffusion effect than wooden diffusion boards.

[0085] Example 2

[0086] This embodiment provides a method for assembling a sound-absorbing diffuser panel, which is the same method provided in Embodiment 1. The assembly method includes the following steps:

[0087] Step 1: Reinforce the first cotton fabric with a plastic edging ring using glue and install it onto the plastic diffusion component.

[0088] Step 2: Repeat Step 1, and so on, to make 4 sets of plastic diffusion parts / cotton cloth combinations.

[0089] Step 3: The aluminum material is extruded into a strip using an extrusion injection molding method, which includes its proper cross-sectional shape.

[0090] Step 4: Next, cut the aluminum strips to the required length, reinforce them with internal brackets and screws, and install them into a square aluminum frame.

[0091] Step 5: After forming the aluminum frame, drill holes. The holes should be positioned relative to the plastic pillars on the plastic diffuser plate, and their diameter should be the screw size.

[0092] Step 6.1: Add a set of adjustable quick-release buckles to each of the two outer sides of the aluminum frame and fix them with rivets. Their function is to quickly install another set of sound-absorbing and diffuser panels.

[0093] Step 6.2: Secure the four sets of plastic diffusion components / cotton cloth assemblies from Step 2 above to the aluminum frame using screws and spacers.

[0094] Step 7: Cut the rock wool into 5 pieces: Arrange them in two layers, place the 4 pieces of the first rock wool on the first layer, and then cover them with the second rock wool.

[0095] Step 8: Next, secure a second piece of cotton fabric, the same size as the large rock wool, to the porous backing plate using nails. The second cotton fabric is to prevent rock wool fibers from leaking out through the perforations in the porous backing plate.

[0096] Step 9: Place the perforated back panel on the back of the aluminum frame and secure it with rivets to complete the installation of the first set of sound-absorbing and diffusing panels.

[0097] The following shows the connection and positional relationship of the second set of sound-absorbing and diffuser panels:

[0098] Step 10: Follow steps 1 to 9 to complete the installation of the second set of sound-absorbing and diffusing panels;

[0099] Step 11: Prepare two dark wood bases;

[0100] Step 11.1: Fix the logo (own brand) to one of the wooden bases with glue.

[0101] Step 11.2: Secure the two wheels to the back of the wooden base with screws.

[0102] Step 11.3: Install the two internal and external thread nuts on another wooden base, and then fit the two lifting seats and the universal seat into the internal and external thread nuts respectively.

[0103] Step 12: Secure the two wooden base plates to the bottom of the second set of sound-absorbing and diffuser aluminum frames using round-headed hex screws.

[0104] Step 13: Place the first set on top of the second set of sound-absorbing and diffuser panels, and secure them firmly with the adjustable quick-locking mechanism to complete the overall installation of the sound-absorbing and diffuser panels.

[0105] In practical implementation, this sound-absorbing and diffuser panel not only achieves a diffusion effect but also reaches a certain level of sound absorption performance. These two functions can be combined for simultaneous use, reducing installation and manufacturing costs. Its quality and performance are both stable.

[0106] This structure (sound-absorbing diffuser) has better performance than traditional wooden diffusers in terms of damping coefficient, especially in terms of vibration attenuation and control in the mid-to-high frequency range, with higher damping, stable structural support and adjustable acoustic performance.

[0107] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model are included within the protection scope of this utility model.
