Description

Technical Field

[0001] This invention relates to the field of acoustic processing technology, and more specifically, to a method for absorbing and reflecting speech propagation. Background Technology

[0002] Traditional sound propagation treatment in spaces such as recording studios, conference rooms, and concert halls is static. Acoustic design is achieved by installing fixed sound-absorbing panels, diffusers, or reflectors on the walls and ceilings. Once the decoration is completed, the acoustic characteristics of the space (such as reverberation time) are basically fixed, thus having the following drawbacks: a. Single-purpose space: A conference room optimized for speech intelligibility (strong sound absorption) cannot be used for music performances or product launches that require warm reverberation and a sense of space. To achieve multiple functions, it is usually necessary to build multiple rooms with different acoustic characteristics, which is extremely costly.

[0003] b. High trial and error costs: Acoustic design is very complex. If the initial design is not satisfactory, the later modification will involve a large-scale disassembly and assembly project, which is time-consuming, labor-intensive and expensive.

[0004] c. Lack of flexibility: The sound field cannot be adjusted in real time according to the content of the specific event (such as an event that includes a speech and a band performance). Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a method for absorbing and reflecting speech that can be transformed from "static" to "dynamic," enabling one-click switching of acoustic scenes and seamlessly switching between sound absorption and reflection modes within the same physical space according to actual needs.

The specific steps are as follows: S1. When recording pure "dry sound" in the recording studio, start the drive component. The drive component drives all the conversion components in the conversion slots to run. The conversion components switch to sound absorption mode to absorb all frequencies of sound near the panel, especially the low frequencies that are difficult to process. This ensures that pure human voices can be recorded on the recording equipment. S2. When recording and mixing are required, the driver component is activated. The driver component drives all the conversion components in the conversion slots to run. The conversion components switch to reflection mode. The reflection mode of the conversion components "shapes" the sound characteristics of the room, making it warm, full, and full of life.

[0020] 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.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0023] Please see Figure 1-6 The present invention provides the following technical solutions: Specifically, this refers to a speech propagation method capable of both absorption and reflection, comprising a panel 1, on which multiple conversion slots 2 arranged in a rectangular array are formed, and conversion components 3 capable of switching between sound absorption and reflection modes are disposed within the conversion slots 2, and a drive component 4 controlling the operation of the conversion components 3 is disposed on the outside of the panel 1. The speech propagation method of this solution applies the above structure, and the specific steps are as follows: S1. When a clean "dry sound" needs to be recorded in the recording studio, the drive component 4 is activated. The drive component 4 drives the conversion components 3 in all conversion slots 2 to operate. The conversion components 3 switch to sound absorption mode to absorb all frequencies of sound near the panel 1, especially the low frequencies that are difficult to process. This ensures that the recording equipment can record pure human voices.

[0024] S2. When recording and mixing are required, start the driver component 4. The driver component 4 drives all the conversion components 3 in the conversion slot 2 to run. The conversion components 3 switch to reflection mode. The reflection mode of the conversion components 3 is used to "shape" the sound characteristics of the room, making it warm, full and full of life.

[0025] The above method transforms sound processing from "static" to "dynamic," enabling one-click switching of acoustic scenes. Within the same physical space, it allows seamless switching between sound absorption and reflection modes according to actual needs, achieving "multi-purpose use of one room" and greatly enhancing the functionality and economic value of the space.

[0026] Specifically, the conversion component 3 includes a conversion plate 31, which is disposed within the conversion groove 2. The upper and lower surfaces of the conversion plate 31 are in contact with the inner wall of the conversion groove 2 and rotate within the conversion groove 2. Sound-absorbing panels 32 and reflective panels 33 are respectively disposed on the front and rear sides of the conversion plate 31. The sound-absorbing panels 32 are made of glass wool or other sound-absorbing materials, and their surfaces have multiple sharp grooves (see attached image). Figure 1 The reflector 33 is made of wood or other reflective material. When in use, the sound-absorbing panel 32 and the reflector 33 can be switched by controlling the conversion plate 31 to rotate 180 degrees.

[0027] Sealing baffles 36 for blocking gaps are provided between the left and right sides of the conversion plate 31 and the inner walls of the left and right sides of the conversion groove 2. Reset grooves 46 are provided on the inner walls of the left and right sides of the conversion groove 2. The side of the sealing baffle 36 closest to the conversion plate 31 contacts the surface of the conversion plate 31, while the other side extends into the reset groove 46 and slides within the reset groove 46.

[0028] When in use, when the conversion plate 31 is rotated to a horizontal position, the two sealing baffles 36 slide towards the side closer to the conversion plate 31. When the sealing baffles 36 slide to contact the surface of the conversion plate 31, the sealing baffles 36 can seal the gap between the conversion plate 31 and the conversion groove 2, minimizing leakage problems during use and ensuring the sound processing effect of the conversion assembly 3.

[0029] Mounting plates 35 are provided on the surfaces of the reflector 33 and the sound-absorbing plate 32 facing the conversion plate 31. A movable push plate 34 is detachably mounted on the side of the mounting plate 35 near the conversion plate 31. The conversion plate 31 is hollow inside, and the movable push plate 34 slides through the conversion plate 31 on the side near the conversion plate 31.

[0030] When the conversion plate 31 rotates, the movable push plate 34 is controlled to move into the conversion plate 31, while the sound-absorbing plate 32 and the reflector plate 33 move towards the side closer to the conversion plate 31. This avoids the problem of mechanical jamming when the conversion plate 31 rotates and the sound-absorbing plate 32 and the reflector plate 33 come into contact with the inner wall of the conversion groove 2, thus ensuring the stability of the conversion assembly 3 during operation.

[0031] A mounting sleeve 341 is provided inside the conversion plate 31 between two movable push plates 34. A contact push rod 342 is slidably mounted on the mounting sleeve 341. A shrinkage groove 347 communicating with the interior of the conversion plate 31 is opened on the surface of the conversion plate 31 near the sealing baffle 36. One end of the contact push rod 342 slides out of the outer surface of the conversion plate 31 through the shrinkage groove 347 and contacts the sealing baffle 36. A sleeve plate 343 is mounted on the outer surface of the end of the contact push rod 342 inside the conversion plate 31. A tension spring 344 is provided between the sleeve plate 343 and the mounting sleeve 341 and is movably mounted on the outer surface of the contact push rod 342. A push plate 345 is provided at the end of the contact push rod 342 away from the sealing baffle 36. A rotating plate 346 is hinged between the push plate 345 and the movable push plate 34.

[0032] When the contact push rod 342 contacts the sealing baffle 36, the sealing baffle 36 exerts a pushing force on the contact push rod 342, causing the contact push rod 342 to move inward toward the conversion plate 31. Simultaneously, the tension spring 344 is stressed and stretched, and the push plate 345 moves synchronously with the contact push rod 342, causing the rotating plate 346 to exert a pushing force on the movable push plate 34. Therefore, the sound-absorbing plate 32 and the reflector plate 33 can be controlled to move away from the conversion plate 31. When the sealing baffle 36 contacts the side of the conversion plate 31, one end of the contact push rod 342 retracts into the retraction groove 347. At this time, the rotating plate 346 pushes the movable push plate 34 the longest distance. The sound-absorbing plate 32 and the reflector plate 33 are flush with the outer surface of the panel 1. This allows the sound-absorbing plate 32 or the reflector plate 33 to make better contact with the sound, ensuring the sound processing effect of the device. When the sealing baffle 36 retracts into the reset slide groove 46 and the conversion plate 31 rotates, the sealing baffle 36 no longer squeezes the contact push rod 342. Therefore, the contact push rod 342 is displaced out of the conversion plate 31 under the pull of the tension spring 344. At the same time, the rotating plate 346 exerts a pulling force on the movable push plate 34, causing the sound-absorbing plate 32 and the reflector plate 33 to move closer to the conversion plate 31. This prevents mechanical jamming during rotation.

[0033] In this invention, the contact push rod 342 is set as an isosceles triangle at one end of the conversion plate 31. When the sealing baffle 36 moves closer to the conversion plate 31, the inclined surface of the contact push rod 342 contacts a corner of the sealing baffle 36, which can also push the contact push rod 342 to move inward into the conversion plate 31. This will not cause the contact push rod 342 to mechanically jam when it contacts a corner of the sealing baffle 36.

[0034] Mounting plate 35 has a mounting tenon 37 on the side near the movable push plate 34. The mounting tenon 37 is an isosceles trapezoid. The movable push plate 34 has a mounting groove 38 on the surface facing the mounting plate 35 that matches the mounting tenon 37. The mounting groove 38 extends out of the surface of one side of the movable push plate 34.

[0035] In use, the conversion plate 31 is rotated 90 degrees, causing the mounting groove 38 to extend outward from the movable push plate 34 and rotate to the front. The sound-absorbing plate 32 or the reflector plate 33 can be removed from the conversion plate 31 by pulling it outward, so that damaged parts can be replaced. Alternatively, complex and non-uniform acoustic patterns can be created on the same wall according to usage requirements, achieving unprecedented fine control and greatly enriching the dimensions of acoustic adjustment.

[0036] The conversion plate 31 is provided with a locking assembly 39 for fixing the mounting tenon 37. The locking assembly 39 includes a fixing block 391, which is located in the conversion plate 31 and between two movable push plates 34. The fixing block 391 has two contraction cavities 392. The movable push plate 34 has a sliding rod 393 on its surface facing the fixing block 391. The other end of the sliding rod 393 slides through into the contraction cavity 392. When the movable push plate 34 moves, the sliding rod 393 slides synchronously in the contraction cavity 392.

[0037] A rotating shaft 394 is rotatably fitted inside the sliding rod 393. One end of the rotating shaft 394, near the contraction cavity 392, extends into the contraction cavity 392. A twisted rod 395 is provided on the inner wall of the contraction cavity 392 facing the rotating shaft 394. A twisted groove 396, spirally fitted onto the outer surface of the twisted rod 395, is formed on the surface of the rotating shaft 394 facing the twisted rod 395. A sliding cavity 397 is formed in the movable push plate 34 near the interior of the sliding rod 393. The other end of the rotating shaft 394 rotatably passes through the sliding cavity 397. A threaded rod 398 is provided at the end of the rotating shaft 394 located in the sliding cavity 397. The outer surface of the threaded rod 398... A locking rod 399 is threaded onto the sliding cavity 397. A limiting slide rod 3913 is provided between the inner walls of the two opposite sides of the sliding cavity 397. A limiting sleeve 3912 is provided on the surface of the locking rod 399 near the limiting slide rod 3913 and is slidably sleeved on the outer surface of the limiting slide rod 3913. A locking groove 3910 is provided on the surface of the mounting tenon 37 near the sliding cavity 397. The other end of the locking rod 399 slides through the mounting tenon 38 and extends into the locking groove 3910. Therefore, the locking rod 399 can restrict the mounting tenon 37, making it impossible for the mounting tenon 37 to slide, thus completing the fixation of the sound-absorbing plate 32 and the reflector plate 33.

[0038] In use, when the conversion plate 31 rotates, the movable push plate 34 moves into the conversion plate 31. At this time, the sliding rod 393 slides synchronously in the contraction cavity 392, and the rotating shaft 394 slides on the outer surface of the twist rod 395 through the twist groove 396. Thus, the rotating shaft 394 rotates under the drive of the twist rod 395, and the threaded rod 398 rotates synchronously with the rotating shaft 394. This causes the locking rod 399 to move towards the side closer to the fixed block 391 under the transmission of the thread teeth of the threaded rod 398, thereby displacing it out of the locking groove 3910. Thus, when the conversion plate 31 rotates ninety degrees, that is, when the conversion plate 31 rotates ninety degrees, the locking rod 399 moves towards the side closer to the fixed block 391, thereby displacing it out of the locking groove 3910. The sound-absorbing plate 32 and the reflector plate 33 can be removed from the conversion plate 31. When the conversion plate 31 is rotated to a horizontal position, the two movable push plates 34 move in opposite directions. At the same time, the sliding rod 393 moves away from the fixed block 391 in the shrinkage cavity 392. Therefore, the rotating shaft 394 reverses under the drive of the twist rod 395, thereby causing the locking rod 399 to move into the locking groove 3910 and into the locking groove 3910, thus completing the fixation of the sound-absorbing plate 32 and the reflector plate 33. This ensures the firmness of the sound-absorbing plate 32 and the reflector plate 33 after installation when the device is in use.

[0039] The surface of the mounting tenon 37 is provided with a reset groove 3911 that communicates with one side of the locking groove 3910. The reset groove 3911 communicates with the side of the locking groove 3910 that extends away from the mounting tenon 38 and onto the surface of the movable push plate 34. When the conversion plate 31 rotates and the mounting tenon 37 shifts, the end of the locking rod 399 located in the mounting tenon 38 contacts the inclined surface of the reset groove 3911. When the locking rod 399 moves to one side of the locking groove 3910, it presses against the inclined surface of the reset groove 3911, causing the mounting tenon 37 to slide into the mounting tenon 38 until the locking rod 399 slides into the locking groove 3910. This structure minimizes the problem of the mounting tenon 37 shifting under centrifugal force during the rotation of the conversion plate 31, which would prevent the locking rod 399 from aligning with the locking groove 3910, thus ensuring the locking effect on the sound-absorbing plate 32 and the reflector plate 33.

[0040] The drive assembly 4 includes an electric push rod 41, which is located on the right side surface of the panel 1. A synchronization cavity 42 is provided on the right side of the panel 1. The synchronization cavity 42 is located on the right side of a set of vertically arranged conversion slots 2. The left end of the telescopic rod of the electric push rod 41 slides through into the synchronization cavity 42. A synchronization plate 43 that slides within the synchronization cavity 42 is provided at one end of the telescopic rod of the electric push rod 41 within the synchronization cavity 42. Multiple drive cavities 45 are provided in parallel vertically within the panel 1. The drive cavities 45 are located below a set of horizontally arranged conversion slots 2. A drive rod 44 is provided on the surface of the synchronization plate 43 facing the drive cavity 45. The other end of the drive rod 44 slides through into the drive cavity 45. A connecting shaft 47 is provided on the lower surface of the conversion plate 31, with its lower end rotatably penetrating into the drive cavity 45. The lower end of the connecting shaft 47 is rotatably connected to the bottom wall of the drive cavity 45. A gear 49 is sleeved on the outer surface of the connecting shaft 47 near the drive rod 44. A toothed plate 410 that meshes with the gear 49 is sleeved on the outer surface of the drive rod 44 near the gear 49.

[0041] In use, by activating the electric push rod 41, the telescopic rod of the electric push rod 41 can drive the synchronous plate 43 to move left and right within the synchronous cavity 42. The drive rod 44 synchronously drives the toothed plate 410 to move left and right. When the toothed plate 410 moves to the left, it can engage and drive the gear 49 to rotate 180 degrees clockwise. When the toothed plate 410 moves to the right, it can engage and drive the gear 49 to rotate 180 degrees counterclockwise.

[0042] Two spindle-shaped cams 48 are fitted on the outer surface of one end of the connecting shaft 47 located in the drive cavity 45. A connecting groove 415 communicating with the drive cavity 45 is opened at the bottom of the reset groove 46. A connecting plate 414 is provided on the lower surface of the sealing baffle 36. The lower side of the connecting plate 414 extends into the drive cavity 45 through the connecting groove 415. The connecting plate 414 slides in the connecting groove 415. Two connecting push rods 411 are provided on the lower side of the connecting plate 414. A connecting sleeve 413 for limiting the connecting push rods 411 is provided on the inner wall of the drive cavity 45. The connecting push rods 411 slide on the connecting sleeve 413. The other end of the connecting push rods 411 contacts the outer surface of the spindle-shaped cams 48 and slides. A reset plate 416 is fitted on the outer surface of the connecting push rod 411 near the spindle-shaped cams 48. A spring 412 is provided between the reset plate 416 and the connecting sleeve 413 and is movably fitted on the outer surface of the connecting push rod 411.

[0043] When the connecting push rod 411 is not in contact with the protruding end of the shuttle-shaped cam 48, the spring 412 will exert a pushing force on the reset plate 416, so that the initial position of the reset plate 416 is close to the side of the shuttle-shaped cam 48. Therefore, the connecting plate 414 is located on the side of the connecting groove 415 close to the conversion groove 2. At this time, the sealing baffle 36 is displaced into the conversion groove 2 and contacts the outer surface of the conversion plate 31. When the connecting shaft 47 rotates from zero degrees to ninety degrees, the protruding end of the shuttle-shaped cam 48 will squeeze the connecting push rod 411, making... The sealing baffle 36 moves into the reset slide groove 46, and at the same time the spring 412 is squeezed and compressed. When the connecting shaft 47 rotates from 90 degrees to 180 degrees, the protruding end of the shuttle cam 48 no longer squeezes the connecting push rod 411. Therefore, under the push of the spring 412, the sealing baffle 36 seals the gap between the conversion plate 31 and the conversion groove 2 again. With the above structure, the displacement of the sealing baffle 36 can be automatically controlled during the rotation of the conversion plate 31 without human control, which improves the practicality of the device.
