Description

Technical Field

[0001] The present invention relates to the technical field of speaker boxes, and more particularly to a speaker box with an embedded tuning insulation layer and an assembling method thereof. Background Art

[0002] A speaker, also known as a loudspeaker system, is a device that can convert electrical signals into sound signals and amplify and transmit them. It is usually composed of key parts such as a speaker unit, a cabinet, and tuning components. In this invention, the speaker we specifically mention is a speaker with an innovatively designed embedded tuning barrier. The purpose of designing this tuning barrier is to optimize the sound transmission effect. Through sophisticated structural design, it can effectively reduce noise interference, thereby significantly improving the user's sound quality experience. In addition, through careful assembly methods, the speaker of the present invention achieves precise control of the internal sound, ensuring the clarity and layering of the sound. Such a design meets the user's pursuit of high-quality sound effects and provides them with a richer and more delicate auditory enjoyment.

[0003] Patent document CN117750256A discloses a speaker enclosure, relating to the technical field of sound-speaker equipment. The speaker enclosure includes a first enclosure, a first speaker assembly, and a first baffle assembly. The first enclosure includes a first sidewall, a second sidewall, a top wall, and a bottom wall. The first speaker assembly is located within the first enclosure and mounted to the first sidewall. The first baffle assembly is connected to the first sidewall and extends toward the second sidewall. By configuring the first baffle assembly within the first enclosure, the present invention divides the space within the enclosure into multiple small areas, effectively reducing resonance within a large space and thereby mitigating the overall resonance effect.

[0004] Traditional tuning partitions form a multi-cavity structure through physical separation to guide the propagation direction of sound waves in different frequency bands. High-frequency sound waves are easily reflected by the partition surface due to their shorter wavelength to form directional radiation, while low-frequency sound waves penetrate the partition material and resonate in the cavity, enhancing the low-frequency response. This structure can reduce the phase distortion caused by sound wave diffraction and improve the accuracy of sound positioning. When the strength of the tuning partition needs to be adjusted, the staff is usually required to open the speaker casing, readjust the inclination angle of the tuning partition or replace the partition material with different materials. The operation is cumbersome and inefficient. Summary of the Invention

The inclined tuning baffle 3 includes a hinged plate 31, and the left and right sides of the front side of the hinged plate 31 are fixedly connected to a connecting rod 32. The outer sides of the two connecting rods 32 are fixedly connected to an L-shaped connecting rod 33. The rear side of the hinged plate 31 is rotatably connected to the inclined tuning plate body 34, and the rear sides of the inner sides of the two L-shaped connecting rods 33 are fixedly connected to a tilt angle control component 36. The rear sides of the left and right sides of the inclined tuning plate body 34 are fixedly connected to the inclined tuning plate cylindrical slider 35. The tilt angle control component 36 includes an angle control component connecting plate 361, and the left and right sides of the front side of the angle control component connecting plate 361 are fixedly connected to The concave connecting plate 362 has side connecting blocks 363 fixedly connected to the left and right sides of the front sides of the two concave connecting plates 362. The inner sides of the left and right sets of side connecting blocks 363 are fixedly connected to columnar lifting rod connecting blocks 364. The inner walls of the two columnar lifting rod connecting blocks 364 are slidably connected to columnar lifting rods 365. The outer walls of the two columnar lifting rods 365 are sleeved with springs 366 on one side of the bottom of the columnar lifting rod connecting blocks 364. The bottoms of the two columnar lifting rods 365 are fixedly connected to both sides of the top of the bottom tuning partition body 215. The tops of the inner sides of the left and right sets of side connecting blocks 363 are rotatably connected to the oblique sound insulation board connecting block rotating blocks 3611. The rear sides of the two oblique sound insulation board connecting block rotating blocks 3611 are fixedly connected to the oblique sound insulation board connecting block 3612.The outer walls of the two oblique sound insulation board connecting blocks 3612 are rotatably connected to the inner sides of the tops of the two concave connecting plates 362. The tops of the two oblique sound insulation board connecting blocks 3612 are rotatably connected to the left and right sides of the bottom of the oblique tuning plate body 34. The front sides of the two oblique sound insulation board connecting blocks 3612 are fixedly connected to the rotating blocks 369. One side of each rotating block 369 has an elliptical groove 3610. The left and right sides of the tops of the two columnar lifting rods 365 are rotatably connected to push-pull rotating rods 367. The tops of the inner sides of the left and right sets of push-pull rotating rods 367 are fixedly connected to the columnar cross bars 368. The outer walls of the two columnar cross bars 368 are slidably connected to the inner walls of the rotating blocks 369 provided with the two elliptical grooves 3610.

[0038] When the sound insulation layer of the inner wall of the speaker needs to be adjusted and weakened, the user starts the electric push rod 24 through the remote control. The front end of the electric push rod 24 pushes the push-pull block 26 to slide forward along the inner wall of the slide groove 23. As the push-pull block 26 moves, it drives the push-pull plate 27 to slide along the slide rail 28. At the same time, the push-pull plate slider 29 on the push-pull plate 27 also slides on the outer wall of the slide rail 28 to ensure the stable movement of the push-pull plate 27. The movement of the push-pull plate 27 drives the block 210 on its top to move together. Since the top of the block 210 is convex, it will move with the pulley 214. The bottom of the speaker body 1 is contacted, thereby pushing the pulley 214 to slide upward along the surface of the stop block 210. The sliding of the pulley 214 will drive the pulley connecting block 213 and the lifting plate slider 211 connected thereto to rise together, and then push the bottom tuning baffle body 215 to rise through the lifting plate connecting vertical plate 212. The bottom tuning baffle body 215 rises away from the bottom of the inner wall of the speaker body 1 until it reaches a predetermined adjustment height. In this process, the distance between the bottom tuning baffle body 215 and the inner wall of the speaker body 1 increases, so that the sound wave transmission path inside the speaker is changed, thereby achieving the purpose of adjusting the sound effect of the speaker.

[0039] At the same time, when the bottom tuning baffle body 215 moves upward, it drives the two columnar lifting rods 365 to move toward the top. The movement of the columnar lifting rods 365 compresses the springs 366, generating elastic force to provide power for the reset of the columnar lifting rods 365. As the columnar lifting rods 365 move upward, the push-pull rotating rod 367 at the top thereof will also rotate accordingly. Since the top of the inner side of the push-pull rotating rod 367 is fixedly connected to the columnar cross bar 368, the outer wall of the columnar cross bar 368 is slidably connected to the opening on the inner wall of the rotating block 369. The columnar crossbar 368 slides along the shape of the elliptical groove 3610, thereby driving the rotating block 369 and the oblique sound insulation board connecting block 3612 connected thereto to rotate. The rotation of the oblique sound insulation board connecting block 3612 drives the oblique sound insulation board body 34 to adjust its tilt angle, thereby changing the angle between the oblique sound insulation board body 34 and the inner wall of the speaker body 1, thereby further changing the sound wave reflection path inside the speaker and enhancing the sound adjustment effect of the speaker.

[0040] During the upward movement of the columnar lifting rod 365, the inner wall of the columnar lifting rod connecting block 364 slides to connect the columnar lifting rod 365. Therefore, the movement of the columnar lifting rod 365 is smooth and controllable, ensuring the accuracy of the inclination angle adjustment of the oblique tuning plate body 34. At the same time, the elastic force of the spring 366 also enables the columnar lifting rod 365 to quickly and accurately return to the initial position when it needs to be reset, ensuring the stability and reliability of the sound effect adjustment of the speaker.

[0041] In addition, when the bottom tuning baffle body 215 rises to a predetermined height, the user can close the electric push rod 24 through the remote control. At this time, the bottom tuning baffle body 215 and its connected parts will remain stable under the elastic force of the spring 366 and will not be displaced by external vibrations or sound waves, thereby ensuring the durability and stability of the sound adjustment effect of the speaker.

[0042] When it is adjusted to be strengthened, at this time, the electric push rod 24 is started in reverse, and the electric push rod 24 is started in reverse to drive the push-pull block 26 to slide backward along the inner wall of the slide groove 23, so that the bottom tuning baffle body 215 drops and approaches the bottom of the inner wall of the speaker body 1 until it reaches the predetermined enhanced adjustment height. In this process, the distance between the bottom tuning baffle body 215 and the inner wall of the speaker body 1 is reduced, so that the sound wave transmission path inside the speaker is changed again, thereby achieving the purpose of further adjusting the sound effect of the speaker. In addition, the inclined tuning plate body 34 is lowered and then rotated upward according to the lowering of the bottom tuning baffle body 215, so that the tilt angle becomes larger. When the requirement for enhancing the sound insulation effect is too high, the bottom tuning baffle body 215 moves further downward and the inclined tuning plate body 34 flips upward.

[0043] In addition, the present invention also relates to a speaker with an embedded tuning insulation layer and an assembly method thereof, comprising the following steps:

[0044] Step 1: Place the speaker body 1 horizontally on the assembly platform and install the electric push rod 24 at the end of the slide 23, ensuring that the push rod axis is parallel to the extension direction of the slide;

[0045] Step 2: Insert the push-pull block 26 into the slide 23, fix its bottom with bolts and connect it to the telescopic end of the electric push rod 24. At the same time, set up two slide rails 28 in parallel above the slide 23, so that the push-pull plate slider 29 at the bottom of the push-pull plate 27 forms a sliding pair with the slide rails 28, and dynamically connect the front end of the push-pull plate 27 to the push-pull block 26 through a hinge mechanism;

[0046] Step 3: Vertically install four sets of lifting plates connecting the vertical plates 212 inside the speaker body 1, and connect the bottom ends of the lifting plates to the bottom tuning baffle body 215 via a rotating shaft;

[0047] Step 4: A symmetrically distributed columnar lifting cavity is opened on the side wall of the speaker body 1, and the columnar lifting rod 365 is installed vertically after being sleeved with a compression spring 366. At the same time, a push-pull rotating rod 367 is installed on the inner wall of the columnar lifting rod 365, and the inner top thereof is fixedly connected to the columnar cross bar 368. The columnar cross bar 368 is slidably connected to the elliptical slide groove 3610 opened on the inner wall of the rotating block 369. The rotating block 369 is fixedly connected to the inclined sound insulation board connecting block 3612, thereby forming a linkage mechanism for adjusting the inclination angle of the inclined tuning plate body 34.

[0048] The working principle of the present invention is: when it is necessary to adjust the sound insulation layer of the inner wall of the speaker and weaken it, the user starts the electric push rod 24 through the remote control. The front end of the electric push rod 24 will push the push-pull block 26 to slide forward along the inner wall of the slide groove 23. As the push-pull block 26 moves, it drives the push-pull plate 27 to slide along the slide rail rod 28. At the same time, the push-pull plate slider 29 on the push-pull plate 27 will also slide on the outer wall of the slide rail rod 28 to ensure the stable movement of the push-pull plate 27. The movement of the push-pull plate 27 will drive the block 210 on its top to move together. Since the top of the block 210 is convex, it will contact the bottom of the pulley 214, thereby pushing the pulley 214 along the surface of the block 210. When the bottom tuning baffle body 215 is lifted up, the distance between the bottom tuning baffle body 215 and the inner wall of the speaker body 1 increases. At the same time, when the bottom tuning baffle body 215 moves upward, the two columnar lifting rods 365 are driven to move toward the top. The movement of the columnar lifting rod 365 compresses the spring 366, generates elastic force, and provides power for the reset of the columnar lifting rod 365. As the speaker 365 moves upward, the push-pull rotating rod 367 at its top will also rotate accordingly. Since the top of the inner side of the push-pull rotating rod 367 is fixedly connected to the columnar cross bar 368, the outer wall of the columnar cross bar 368 is slidably connected to the elliptical slide 3610 provided on the inner wall of the rotating block 369. Therefore, the columnar cross bar 368 will slide along the shape of the elliptical slide 3610, thereby driving the rotating block 369 and the oblique sound insulation board connecting block 3612 connected thereto to rotate. The rotation of the oblique sound insulation board connecting block 3612 will drive the oblique tuning plate body 34 to adjust the tilt angle, so that the angle between the oblique tuning plate body 34 and the inner wall of the speaker body 1 changes. When the adjustment is strengthened, at this time, the electric push rod 24 is started in the reverse direction. The electric push rod 24 starts in the reverse direction and drives the push-pull block 26 to slide backward along the inner wall of the slide groove 23, so that the bottom tuning baffle body 215 drops and approaches the bottom of the inner wall of the speaker body 1 until it reaches the predetermined enhanced adjustment height. In this process, the distance between the bottom tuning baffle body 215 and the inner wall of the speaker body 1 is reduced, so that the sound wave transmission path inside the speaker is changed again, thereby achieving the purpose of further adjusting the sound effect of the speaker. In addition, the inclined tuning plate body 34 is lowered and then rotated upward according to the descent of the bottom tuning baffle body 215, so that the tilt angle becomes larger. When the requirement for enhancing the sound insulation effect is too high, the bottom tuning baffle body 215 moves further downward and the inclined tuning plate body 34 flips further upward.
