Description

Technical Field

[0001] This invention relates to the field of sound-absorbing diffusers, and in particular to an MLS diffuser. Background Technology

[0002] In the fields of audio engineering and interior acoustic design, MLS (Maximum Length Sequence Diffuser) diffusers are widely used to improve sound distribution, enhance sound quality, and control reverberation. MLS diffusers are designed to effectively diffuse sound waves through specific geometry and material properties, thereby reducing parallel reflections and improving the audio experience.

[0003] However, existing MLS diffusers have some limitations and potential drawbacks in practical applications: because the diffusion effect of MLS diffusers usually performs best within their design frequency range, their diffusion effect will be significantly weakened for sound waves outside the frequency range, even approaching specular reflection; this frequency dependence means that in some environments, MLS diffusers cannot provide a uniform sound wave diffusion effect, thus affecting sound quality and listening experience. Summary of the Invention

[0004] The purpose of this invention is to provide an MLS diffuser that can provide uniform sound diffusion and improve the auditory experience.

[0005] To achieve the above objectives, the present invention provides an MLS diffuser, comprising: a mounting plate, a plurality of MLS diffuser bodies, and a plurality of connecting rods extending along a first direction;

[0006] The mounting plate has a mounting surface located in the first direction. The MLS diffuser body includes a substrate and a plurality of MLS diffuser units. The plurality of MLS diffuser units are disposed on the peripheral wall of the substrate along the first direction. Each substrate is connected to each of the connecting rods in a one-to-one correspondence and is slidably connected to the mounting surface through the connecting rods. The plurality of MLS diffuser bodies are arranged in an array on the mounting surface and can move closer to or further away from the mounting surface along the first direction through the connecting rods.

[0007] Furthermore, the substrate has a first surface and a second surface disposed opposite to each other along the first direction, and the outer surface of each MLS diffuser unit in a portion of the MLS diffuser body is flush with the first surface along the first direction near the first surface, and the outer surface of each MLS diffuser unit in a portion of the MLS diffuser body is flush with the second surface along the first direction near the second surface.

[0008] Furthermore, the mounting plate has a plurality of mounting holes extending along the first direction, and the connecting rod includes a positioning component and a first rod body. The first rod body is slidably inserted through the mounting holes, and the positioning component is connected to the mounting plate and is limited in cooperation with the first rod body.

[0009] Furthermore, the mounting plate has an adjustment surface disposed relative to the mounting surface along a first direction, and the positioning component includes a positioning sleeve and a positioning knob. The positioning sleeve is sleeved on the first rod and fixedly connected to the adjustment surface, and the positioning knob is rotatably disposed on the positioning sleeve and used for limiting cooperation with the first rod.

[0010] Furthermore, the connecting rod also includes a second rod body, which is sleeved on the end of the first rod body near the adjusting surface and is fixedly connected to the adjusting surface.

[0011] Furthermore, the projection of the substrate in the first direction is a square or a rectangle.

[0012] Furthermore, the substrate includes two first edge surfaces disposed opposite each other along a second direction and two second edge surfaces disposed opposite each other along a third direction. The first edge surfaces and the second edge surfaces are staggered and connected end to end to define the peripheral wall of the substrate in the first direction. At least three MLS diffuser units are sequentially spaced along the third direction on the first edge surfaces, and at least five MLS diffuser units are sequentially spaced along the second direction on the second edge surfaces. Wherein, any two of the first direction, the second direction and the third direction are perpendicular to each other.

[0013] Furthermore, the plurality of MLS diffuser bodies are arranged in at least 5 rows along a third direction and in at least 4 columns along a second direction on the mounting surface. The distance between each column of MLS diffuser bodies and the mounting surface is equal, and the distance between adjacent columns of MLS diffuser bodies and the mounting surface increases sequentially along the second direction.

[0014] Furthermore, each MLS diffuser unit that is flush with the first surface is defined as a first MLS diffuser body, and each MLS diffuser unit that is flush with the second surface is defined as a second MLS diffuser body. In each row of MLS diffuser bodies, the first MLS diffuser bodies and the second MLS diffuser bodies are arranged alternately at intervals.

[0015] Furthermore, the spacing between two adjacent MLS diffuser bodies is 15mm to 25mm.

[0016] Compared with the prior art, the beneficial effects of the MLS diffuser of this invention are as follows:

[0017] The MLS diffuser of this invention can flexibly adjust the height and number of the MLS diffuser body as needed, which can effectively disperse sound waves and break the parallel reflection of sound waves. When used in places with high requirements for clarity and dry sound environment, it can provide a richer sound quality and auditory experience and present a more natural diffusion mode.

[0029] In the description of this invention, it should be understood that the terms "connected," "linked," and "fixed," etc., used in this invention should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or a welded connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly defined. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] In this invention, the terms "first," "second," etc., are used to describe various types of information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0031] Reference Figure 1 An MLS diffuser according to an embodiment of the present invention includes: a mounting plate 1, a plurality of MLS diffuser bodies 2, and a plurality of connecting rods 3 extending along a first direction x; the mounting plate 1 has a mounting surface 11 located in the first direction x, the MLS diffuser body 2 includes a substrate 21 and a plurality of MLS diffuser units 22, the plurality of MLS diffuser units 22 are disposed around the peripheral wall of the substrate 21 along the first direction x, each substrate 21 is connected to each of the connecting rods 3 in a one-to-one correspondence, and is slidably connected to the mounting surface 11 through the connecting rods 3, the plurality of MLS diffuser bodies 2 are arranged in an array on the mounting surface 11, and can move closer to or away from the mounting surface 11 along the first direction x through the connecting rods 3.

[0032] The MLS diffuser body 2 is slidably connected to the mounting plate 1 via the connecting rod 3. During use, the distance between the MLS diffuser body 2 and the mounting surface 11 can be adjusted according to specific needs, i.e., the height of the MLS diffuser body 2 on the mounting surface 11. The space of the MLS diffuser body 2 on the mounting plate 1 can also be reasonably arranged by adding or removing MLS diffusers, so that the MLS diffuser can more effectively diffuse the sound from the stage, allowing performers to better perform at their best and creating an ideal auditory environment for users.

[0033] refer to Figure 4 and Figure 5 In some improvements of this application, the substrate 21 has a first surface 211 and a second surface 212 disposed opposite to each other along the first direction x. Some of the MLS diffuser units 22 in the MLS diffuser body 2 are flush with the outer surface of the first surface 211 along the first direction x, and some of the MLS diffuser units 22 are flush with the outer surface of the second surface 212 along the first direction x. All MLS diffuser units 22 are of the same size and height. Designing the MLS diffuser body 2 in these two forms allows for fine adjustment of the height of the MLS diffuser units 22 that actually function on the MLS diffuser body 2, further dispersing sound waves, better breaking parallel reflections of sound waves, and presenting a more natural diffusion pattern.

[0034] refer to Figure 2 and Figure 3 In some improvements of this application, the mounting plate 1 has multiple mounting holes 10 extending along the first direction x. The connecting rod 3 includes a positioning component 31 and a first rod body 32. The first rod body 32 slides through the mounting holes 10 along the first direction x. The positioning component 31 is connected to the mounting plate 1 and engages with the first rod body 32 for limiting. By sliding the first rod body 32, the height of the MLS diffuser body 2 relative to the mounting surface 11 can be directly controlled. The first rod body 32 is fixed by the positioning component 31. This design greatly facilitates the initial installation, adjustment, and subsequent debugging and adjustment of the MLS diffuser, and can reduce construction costs and subsequent maintenance expenses.

[0035] refer to Figure 6In some improvements of this application, the mounting plate 1 has an adjustment surface 12 disposed relative to the mounting surface 11 along a first direction x. The positioning component 31 includes a positioning sleeve 311 and a positioning knob 312. The positioning sleeve 311 is sleeved on the first rod 32 and fixedly connected to the adjustment surface 12. The positioning knob 312 is rotatably disposed on the positioning sleeve 311 and is used for limiting engagement with the first rod 32. Specifically, the positioning sleeve 311 may have a tapered clamping part, and the positioning knob 312 may be sleeved on the clamping part, fixing the position of the first rod 32 by tightening the clamping part with threads; or the positioning knob 312 may be radially inserted into the peripheral wall of the positioning sleeve 311 along the first rod 32, controlling the distance to the peripheral wall of the first rod 32 with threads, and limiting its position by abutting against the peripheral wall of the first rod 32. After adjusting the MLS diffuser body 2 to a suitable height using the first rod 32, the positioning knob 312 is tightened for limiting.

[0036] In some improvements of this application, the connecting rod 3 further includes a second rod body 33, which is sleeved on the end of the first rod body 32 near the adjusting surface 12 and fixedly connected to the adjusting surface 12. The second rod body 33 is used to accommodate the end of the first rod body 32 that is away from the MLS diffuser body 2, so that the protrusion height of the connecting rod 3 relative to the adjusting surface 12 remains consistent, thereby improving the aesthetics of the MLS diffuser.

[0037] In some improvements of this application, the projection of the substrate 21 in the first direction x is a square, a rectangle, or a circle.

[0038] In some improvements of this application, the substrate 21 includes two first edge surfaces 213 disposed opposite to each other along the second direction y and two second edge surfaces 214 disposed opposite to each other along the third direction z. The first edge surfaces 213 and the second edge surfaces 214 are staggered and connected end to end to define the peripheral wall of the substrate 21 in the first direction x. At least three MLS diffuser units 22 are sequentially spaced on the first edge surfaces 213 along the third direction z, and at least five MLS diffuser units 22 are sequentially spaced on the second edge surfaces 214 along the second direction y. Wherein, any two of the first direction x, the second direction y and the third direction z are perpendicular to each other.

[0039] In a specific embodiment of this application, the substrate 21 is rectangular, with its long side extending along the second direction y and its short side extending along the third direction z.

[0040] refer to Figure 7In some improvements of this application, multiple MLS diffuser bodies 2 are arranged in at least 5 rows along the third direction z on the mounting surface 11 and in at least 4 columns along the second direction y. The distance between each column of MLS diffuser bodies 2 and the mounting surface 11 is equal, and the distance between adjacent columns of MLS diffuser bodies 2 and the mounting surface 11 increases sequentially along the second direction y.

[0041] In some improvements of this application, the MLS diffuser body 2 that is flush with the first surface 211 is defined as the first MLS diffuser body 2, and the MLS diffuser unit 22 that is flush with the second surface 212 is defined as the second MLS diffuser body 2. The first MLS diffuser body 2 and the second MLS diffuser body 2 are staggered in each row of MLS diffuser bodies 2. The arrangement of the MLS diffuser bodies 2 can be flexibly adjusted according to the seven-tone scale, improving the three-dimensional diffusion of the seven-tone scale, effectively improving the acoustic environment, effectively adjusting the diffusion effect of the MLS diffuser unit 22 at different frequencies, making the sound diffusion uniform, and extending the reverberation time, ensuring the uniform distribution of sound in space.

[0042] The first MLS diffuser body 2 and the second MLS diffuser body 2 are arranged alternately on the mounting plate 1, forming an undulating shape. The MLS diffuser units 22 at different heights on the MLS diffuser bodies 2, as well as the spatial gaps formed between them, play a role in controlling reverberation time, reducing echoes and reflections, improving sound clarity and uniformity, and enhancing the spatial sense and immersive feeling of the music.

[0043] In some improvements of this application, the spacing between two adjacent MLS diffuser bodies 2 is 15mm to 25mm.

[0044] In summary, this embodiment of the invention provides an MLS diffuser that allows for adjustment of the height or number of MLS diffuser bodies 2 as needed, thereby creating a structure with varying heights. This flexibility allows the acoustic environment created by the MLS diffuser to be optimized according to specific requirements. The staggered MLS diffuser units 22 and the spatial gaps between them effectively control reverberation time, reduce echoes and reflections, thereby improving sound clarity and uniformity, and enhancing the overall acoustic effect. The arrangement of the MLS diffuser bodies 2 on the mounting plate 1 can be flexibly adjusted according to the musical scale, enhancing the three-dimensional diffusion of the 7-tone scale. This effectively improves the sound wave diffusion effect at different frequencies, ensuring uniform sound propagation.

[0045] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
