A subwoofer with resonance suppression base

Abstract

This utility model relates to the field of subwoofer technology and discloses a subwoofer with a resonance suppression base, including a speaker body. A placement plate is attached to the bottom of the speaker body, and a U-shaped frame is attached to the top of the placement plate. A rubber pad is fixedly fitted to the inner wall of the U-shaped frame, and the inner wall of the rubber pad is in close contact with the side of the speaker body. Through the cooperation of a sliding rod and a sliding cylinder, when the speaker body drives the placement plate to vibrate, the placement plate drives the outer edge of the sliding rod to slide within the inner wall of the inner cylinder, and the outer edge of the sliding cylinder to slide within the inner wall of the outer cylinder. The inner wall of the sliding cylinder slides within the outer edge of the inner cylinder, thereby driving the magnet ring to slide within the inner wall of the coil. The coil then generates electromagnetic damping on the magnet ring, thus assisting in vibration reduction of the speaker body. Furthermore, the use of aluminum to make the sliding cylinder, outer cylinder, sliding rod, and inner cylinder confines the alternating magnetic field generated by the magnet ring and coil within the cylinder, reducing outward radiation and ensuring stable operation of the speaker body.

Description

Technical Field

[0001] This utility model relates to the field of subwoofer technology, specifically a subwoofer with a resonance suppression base. Background Technology

[0002] Subwoofers are typically speakers designed to enhance low-frequency sound effects. Their main function is to improve low-frequency sound performance, creating a stronger sense of atmosphere and a more impactful effect. To help subwoofers operate stably, a subwoofer with a resonance suppression base is required.

[0003] In traditional devices, the subwoofer is usually placed on top of the base. However, during operation, the subwoofer cabinet and base are prone to vibration, which can lead to resonance and affect the stable transmission of the subwoofer's sound. In addition, traditional devices cannot guarantee that the cabinet can be mounted on top of the base with screws, thus affecting the efficiency of the cabinet's assembly and disassembly. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a subwoofer with a resonance suppression base to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a subwoofer with a resonance suppression base, comprising a speaker body, a placement plate attached to the bottom of the speaker body, a U-shaped frame attached to the top of the placement plate, a rubber pad fixedly fitted to the inner wall of the U-shaped frame, and the inner wall of the rubber pad tightly fitting against the side of the speaker body, a sliding groove provided at the top of the U-shaped frame, a cylinder fixedly fitted to the bottom of the placement plate, a sliding cylinder fixedly fitted to the bottom of the placement plate, an outer cylinder slidably sleeved on the outer edge of the sliding cylinder, a fixing seat fixedly fitted to the bottom of the outer cylinder, a coil fixedly sleeved on the inner wall of the outer cylinder, and a magnet ring fixedly fitted to the bottom of the sliding cylinder, with the outer edge of the magnet ring slidably sleeved against the inner wall of the coil.

[0006] As a preferred technical solution of this utility model, the top of the placement plate is provided with a second sliding groove, the top of the cylinder is provided with an arc-shaped groove, the inner wall of the arc-shaped groove is rotatably connected to a limiting plate, and the shape and size of the outer edge of the limiting plate are adapted to the shape and size of the inner wall of the second sliding groove and the shape and size of the inner wall of the first sliding groove.

[0007] As a preferred embodiment of this utility model, a round rod is fixedly mounted on the top of the limiting plate, an adjusting plate is fixedly mounted on the top of the round rod, an auxiliary cylinder is fixedly mounted on the U-shaped frame, an auxiliary rod is slidably sleeved on the inner wall of the auxiliary cylinder, and the outer edge of the auxiliary rod is slidably sleeved on the inner wall of the adjusting plate.

[0008] As a preferred embodiment of this utility model, an adjusting block is fixedly mounted on the outer edge of the auxiliary rod, and the side of the adjusting block is slidably connected to the outer edge of the auxiliary cylinder.

[0009] As a preferred embodiment of this utility model, a sliding rod is fixedly mounted on the bottom of the placement plate, and the outer edge of the sliding rod is fixedly sleeved with the inner wall of the sliding cylinder. An inner cylinder is slidably sleeved on the inner wall of the sliding cylinder, and the bottom of the inner cylinder is fixedly mounted with the bottom of the inner wall of the outer cylinder. The inner wall of the inner cylinder is slidably sleeved with the outer edge of the sliding rod.

[0010] As a preferred technical solution of this utility model, the sliding cylinder, outer cylinder, sliding rod, and inner cylinder are all made of aluminum. There are four sliding cylinders, which are evenly distributed at the bottom of the placement plate. The connection structure of the outer edges of the four sliding cylinders is completely identical.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This subwoofer with resonance suppression base uses a sliding rod and a sliding cylinder in combination. When the speaker body drives the placement plate to vibrate, the placement plate drives the outer edge of the sliding rod to slide in the inner wall of the inner cylinder, and drives the outer edge of the sliding cylinder to slide in the inner wall of the outer cylinder. The inner wall of the sliding cylinder slides in the outer edge of the inner cylinder, and then the sliding cylinder drives the magnet ring to slide in the inner wall of the coil. The coil then generates electromagnetic damping on the magnet ring, thereby assisting the speaker body in reducing vibration. Furthermore, the use of aluminum to make the sliding cylinder, outer cylinder, sliding rod, and inner cylinder confines the alternating magnetic field generated by the magnet ring and coil inside the cylinder, reducing outward radiation and ensuring stable operation of the speaker body.

[0012] 2. This subwoofer with resonance suppression base uses a limiting plate and an adjusting plate in conjunction. The adjusting block moves the outer edge of the auxiliary rod away from the inner wall of the adjusting plate. Then, the adjusting plate is rotated, which in turn moves the limiting plate through the round rod to rotate within the inner wall of the arc-shaped groove. Then, the adjusting plate is moved upward, which helps the outer edge of the limiting plate move along the inner wall of the second slide and the inner wall of the first slide, thus assisting in the quick disassembly of the U-shaped frame and the placement plate, and consequently, the quick disassembly of the speaker body.

Through the cooperation of the outer cylinder 18 and the slide cylinder 17, the slide cylinder 17 drives the magnet ring 20 to slide in the inner wall of the coil 19. The coil 19 then generates electromagnetic damping on the magnet ring 20, thereby assisting the slide cylinder 17 in driving the speaker body 1 through the placement plate 2 to perform auxiliary vibration reduction.

[0017] In a preferred embodiment, the top of the placement plate 2 is provided with a second sliding groove 6, and the top of the cylinder 7 is provided with an arc-shaped groove 8.

Through the cooperation of the second sliding groove 6 and the first sliding groove 5, the outer edge of the limiting plate 10 passes through the inner wall of the first sliding groove 5 and the inner wall of the second sliding groove 6 to the inner wall of the arc-shaped groove 8, thereby rotating the limiting plate 10 and assisting the limiting plate 10 to be limited to the inner wall of the arc-shaped groove 8.

[0018] In a preferred embodiment, a round rod 11 is fixedly mounted on the top of the limiting plate 10, an adjusting plate 12 is fixedly mounted on the top of the round rod 11, an auxiliary cylinder 13 is fixedly mounted on the U-shaped frame 3, an auxiliary rod 14 is slidably sleeved on the inner wall of the auxiliary cylinder 13, and the outer edge of the auxiliary rod 14 is slidably sleeved on the inner wall of the adjusting plate 12. Through the cooperation of the auxiliary rod 14 and the adjusting plate 12, the limiting plate 10 is rotated by the adjusting plate 12 through the round rod 11, and the outer edge of the auxiliary rod 14 is connected to the inner wall of the adjusting plate 12 for limiting, thereby further assisting the limiting plate 10 in limiting.

[0019] In a preferred embodiment, an adjusting block 15 is fixedly mounted on the outer edge of the auxiliary rod 14, and the side of the adjusting block 15 is slidably connected to the outer edge of the auxiliary cylinder 13. Through the cooperation of the adjusting block 15 and the auxiliary rod 14, the adjusting block 15 drives the auxiliary rod 14 to adjust its position, thereby driving the outer edge of the auxiliary rod 14 to be limited to the inner wall of the adjusting plate 12, thus ensuring that the limiting plate 10 is limited.

[0020] In a preferred embodiment, a slide rod 16 is fixedly mounted on the bottom of the placement plate 2, and the outer edge of the slide rod 16 is fixedly sleeved with the inner wall of the slide cylinder 17. An inner cylinder 21 is slidably sleeved on the inner wall of the slide cylinder 17, and the bottom of the inner cylinder 21 is fixedly mounted with the bottom of the inner wall of the outer cylinder 18. The inner wall of the inner cylinder 21 is slidably sleeved with the outer edge of the slide rod 16. Through the cooperation of the slide rod 16 and the inner cylinder 21, the outer edge of the slide rod 16 slides in the inner wall of the inner cylinder 21, and the inner wall of the slide cylinder 17 slides in the outer edge of the inner cylinder 21, and the outer edge of the slide cylinder 17 slides in the inner wall of the outer cylinder 18, thereby assisting in limiting the movement path of the placement plate 2.

[0021] In a preferred embodiment, the slide cylinder 17, the outer cylinder 18, the slide rod 16, and the inner cylinder 21 are all made of aluminum. There are four slide cylinders 17, and the four slide cylinders 17 are evenly distributed at the bottom of the placement plate 2. The connection structure of the outer edges of the four slide cylinders 17 is completely identical. By adding the four slide cylinders 17, the placement plate 2 can be moved stably and limited, thereby further ensuring the stability of the speaker body 1 and suppressing resonance.

[0022] Working principle: When the speaker body 1 is mounted on top of the placement plate 2, when the speaker body 1 causes the placement plate 2 to vibrate, the placement plate 2 causes the outer edge of the slide rod 16 to slide within the inner wall of the inner cylinder 21, and the outer edge of the slide cylinder 17 to slide within the inner wall of the outer cylinder 18. The inner wall of the slide cylinder 17 slides within the outer edge of the inner cylinder 21, thereby causing the magnet ring 20 to slide within the inner wall of the coil 19. The coil 19 then generates electromagnetic damping on the magnet ring 20, thus assisting the speaker body 1 in reducing vibration. The slide cylinder 17, outer cylinder 18, slide rod 16, and inner cylinder 21 are made of aluminum, which is used to house the magnet... The alternating magnetic field generated by the ring 20 and the coil 19 is confined inside the cylinder, reducing outward radiation and thus ensuring the stable operation of the speaker body 1. The adjustment block 15 drives the outer edge of the auxiliary rod 14 away from the inner wall of the adjustment plate 12. Then, the adjustment plate 12 is rotated, thereby using the adjustment plate 12 to drive the limiting plate 10 to rotate in the inner wall of the arc groove 8 through the round rod 11. Then, the adjustment plate 12 is moved upward, thereby assisting the outer edge of the limiting plate 10 to move the adjustment plate 12 along the inner wall of the second slide groove 6 and the inner wall of the first slide groove 5, thereby assisting the quick disassembly of the U-shaped frame 3 and the placement plate 2, and thus assisting the quick disassembly of the speaker body 1.
