Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a loudspeaker anti-shake structure and an audio system. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals. The performance of a loudspeaker greatly affects sound quality. While it is the weakest component in an audio system, it is also one of the most crucial for sound effects. There are many types of loudspeakers with vastly different prices. Audio energy, through electromagnetic, piezoelectric, or electrostatic effects, causes the cone or diaphragm to vibrate and resonate with the surrounding air, producing sound. The voice coil is the driving unit of a cone-shaped loudspeaker. It is made of very thin copper wire wound in two layers around a paper tube, typically dozens of turns, and is placed in the magnetic gap formed by the magnetic core and magnetic plate. The voice coil is fixed to the cone. When an audio current signal is passed through the voice coil, its vibration drives the cone to vibrate. The materials used for the cone-shaped diaphragm of a cone-shaped loudspeaker are of many types, generally falling into two categories: natural fibers and synthetic fibers. Natural fibers are often made of cotton, wood, wool, silk, etc., while man-made fibers are made of rayon, nylon, glass fiber, etc. Since the cone is the sound radiating device of the loudspeaker, it largely determines the sound performance of the loudspeaker.

[0003] According to patent application number 202421264771.7 published on the China Patent Network, the patent title is: "A Speaker Anti-vibration Structure and Audio System," which includes a speaker and an anti-vibration device. The speaker has a sound output end and a tail end. The anti-vibration device includes a rotating component with a rotating shaft, one end of which is connected to the tail end of the speaker. In this invention, the speaker anti-vibration structure is located at the tail end of the speaker. The high-speed rotation of the anti-vibration device counteracts the circumferential and irregular vibrations generated during speaker operation, thereby reducing phase jitter caused by other vibration interferences in the speaker, reducing noise and distortion, and ensuring that the sound waves radiated by the speaker are consistent with the applied audio signal in both the time and frequency domains, and are in phase. This results in clearer and more accurate sound quality, further enhancing the overall sound system's sense of layering, positioning, and spatiality.

[0004] However, the existing speaker connection method is relatively simple, mainly relying on threaded components for fixing. Its rear end is directly suspended inside the shell. When the speaker vibrates, the suspended end of the speaker shakes more, affecting the sound output effect. Utility Model Content

[0005] The purpose of this invention is to solve the problem of poor speaker installation stability in the prior art, and to propose a speaker anti-shake structure and sound system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A speaker anti-shake structure includes a speaker module. A mounting ring is fixedly connected to the front of the speaker module, and a connecting block is fixedly connected to the back of the speaker module. A bracket is movably connected to the inner side of the connecting block via a pin. The side of the bracket away from the connecting block can contact an external support and support the speaker module. A positioning structure is provided on the back of the speaker module, which can control the swing angle of the bracket. This structure provides active anti-shake functionality through the bracket and positioning structure, effectively reducing speaker displacement in vibrating or moving environments, thereby improving sound quality stability and clarity. The swingable design of the bracket allows it to adapt to uneven surfaces, while the positioning structure precisely controls the angle to prevent loosening or resonance. Advantages include easy installation, high mechanical reliability, suitability for car or portable audio systems, extended device lifespan, and reduced maintenance requirements.

[0007] As a preferred technical solution of this application, the positioning structure includes a rotating wheel disposed on the back of the speaker module. A screw is fixedly connected to the front end of the rotating wheel, and a pressing plate is movably connected to the front end of the screw via a bearing. A force-bearing plate located outside the pressing plate is fixedly connected to the side of the bracket near the connecting block. The force-bearing plate is slidably connected to the pressing plate. This positioning structure moves the pressing plate by driving the screw through the rotating wheel, pushing the force-bearing plate to finely adjust the bracket angle, achieving high-precision control. Functionally, it provides stable force transmission, ensuring that the bracket is firmly locked in the set position and reducing vibration transmission. The effect is to optimize the support point, avoid angle drift, and improve anti-shake performance. Advantages include simple operation, high mechanical efficiency, suitability for frequent adjustment scenarios, such as stage sound systems, and enhanced user-friendliness and durability.

[0008] As a preferred technical solution of this application, a support plate is fixedly connected to the surface of the extrusion plate. The side of the support plate away from the extrusion plate contacts the back of the speaker module. The support plate adds additional support points to enhance the stability of the extrusion plate, prevent it from tilting or shifting during screw operation, and distribute the force to ensure uniform operation of the positioning structure and reduce mechanical stress. The effect is to improve the overall structural rigidity, avoid component wear, and the advantages include simplified assembly process, improved reliability, and extended service life. Especially in high-vibration environments, it can effectively maintain the anti-vibration effect.

[0009] As a preferred technical solution of this application, a spring plate is fixedly connected to the inner side of the bracket. The side of the spring plate away from the bracket contacts the surface of the speaker module. The spring plate is elastic and absorbs vibration and impact energy through elastic contact, reducing the force transmitted to the bracket and thus providing buffer protection. It acts as a secondary anti-shake layer to supplement the stability of the main bracket. The effect is to improve the clarity of sound quality and prevent the speaker assembly from being damaged under dynamic load. The advantages include low-cost integration, enhanced overall anti-shake performance, and it is especially suitable for high-volume or impact environments, improving equipment toughness and user experience.

[0010] As a preferred technical solution of this application, the outer surface of the speaker module is fixedly connected with a number of reinforcing ribs. The side of the reinforcing ribs away from the speaker module is fixedly connected to the back of the mounting ring. The reinforcing ribs strengthen the connection between the speaker module and the mounting ring, increase the overall structural strength, prevent deformation or bending, distribute mechanical load, reduce the risk of resonance, and improve the fixation of the mounting ring, ensuring that the speaker remains stable during vibration. The advantages include simple manufacturing, low cost, suitability for heavy-duty applications, significant extension of equipment life and optimization of sound quality output.

[0011] An audio system employing this speaker vibration damping structure includes an audio enclosure that wraps around the surface of a speaker module. A mounting ring is fitted into the front side of the inner wall of the audio enclosure. The audio enclosure is fitted onto the surface of a screw and threadedly connected to it. A bracket, located away from the connecting block, contacts the inner wall of the audio enclosure. This integrated vibration damping structure provides comprehensive vibration control through enclosure wrapping and internal contact points. The fitting of the mounting ring and the bracket's contact with the inner wall achieve internal stability, reducing the impact of external impacts, improving overall sound quality consistency, and preventing enclosure resonance. Advantages include ease of assembly, low maintenance costs, suitability for home or professional audio systems, enhanced durability and performance, especially in mobile or high-volume scenarios.

[0012] As a preferred technical solution of this application, the rotating wheel is located on the back of the speaker enclosure, the speaker enclosure is provided with a groove, and the rotating wheel is located inside the groove.

[0013] Compared with the prior art, this utility model provides a speaker anti-shake structure and a sound system, which has the following beneficial effects: 1. The speaker anti-vibration structure and audio system achieve multi-angle support through a swingable bracket, flexibly adapting to different external housings. The positioning structure actively controls the bracket's unfolding angle to avoid support failure due to vibration.

[0014] 2. The speaker anti-shake structure and sound system generate linear displacement through the rotary wheel drive screw. The bearing connection ensures that the extrusion plate moves horizontally without deviation, avoiding jamming. The sliding contact between the force plate and the extrusion plate converts the thrust into the support torque, resulting in high mechanical transmission efficiency.

[0015] 3. The speaker anti-shake structure and sound system form an auxiliary fulcrum by having a support plate closely attached to the back of the speaker module, which counteracts the bending moment of the screw thrust on the module body and avoids structural deformation caused by single-point stress.

[0016] 4. The speaker anti-shake structure and sound system form a bidirectional constraint by setting a spring plate to elastically press the surface of the module, so that the bracket has an elastic reset effect.

[0017] 5. The speaker anti-vibration structure and sound system, through the addition of reinforcing ribs, can improve the connection strength between the speaker module and the mounting ring, thus preventing vibration transmission.

[0018] 6. The speaker's anti-vibration structure and sound system, through a fitting and plugging design, ensure that there is no relative displacement between the mounting ring and the cabinet, while the threaded connection enables stable control of the extrusion plate.

[0022] Reference Figures 1-5A speaker anti-shake structure includes a speaker module 1. A mounting ring 2 is fixedly connected to the front of the speaker module 1, and a connecting block 3 is fixedly connected to the back of the speaker module 1. A bracket 4 is movably connected to the inner side of the connecting block 3 via a pin. The side of the bracket 4 away from the connecting block 3 can contact an external support and support the speaker module 1. A positioning structure 5 is provided on the back of the speaker module 1. The positioning structure 5 can control the swing angle of the bracket 4, achieving multi-angle support through the swingable bracket 4, flexibly adapting to different external housings. The positioning structure 5 actively controls the unfolding angle of the bracket 4 to avoid support failure due to vibration. The positioning structure 5 includes a rotating wheel 6 located on the back of the speaker module 1. A screw 7 is fixedly connected to the front end of the rotating wheel 6, and a pressing plate 8 is movably connected to the front end of the screw 7 via a bearing. A force-bearing plate 9 located outside the pressing plate 8 is fixedly connected to the side of the bracket 4 near the connecting block 3. The force plate 9 is slidably connected to the extrusion plate 8. A support plate 10 is fixedly connected to the surface of the extrusion plate 8. The side of the support plate 10 away from the extrusion plate 8 contacts the back of the speaker module 1. A spring plate 11 is fixedly connected to the inner side of the bracket 4. The side of the spring plate 11 away from the bracket 4 contacts the surface of the speaker module 1. The spring plate 11 is elastic. Several reinforcing ribs 12 are fixedly connected to the outer surface of the speaker module 1. The side of the reinforcing ribs 12 away from the speaker module 1 is fixedly connected to the back of the mounting ring 2. The speaker enclosure 13 is wrapped around the surface of the speaker module 1. The front of the mounting ring 2 is fitted into the front side of the inner wall of the speaker enclosure 13.

The speaker enclosure 13 is provided with a groove. The rotating wheel 6 is located inside the groove.

[0023] Specifically, the speaker anti-shake structure and the speaker during operation / use are as follows: The front of the speaker module 1 is embedded into the front side of the inner wall of the speaker enclosure 13 through the mounting ring 2, while the back is connected to the swingable bracket 4 through the connecting block 3 and the pin. When adjustment is required, the rotating wheel 6 located on the back of the speaker enclosure 13 is rotated, which drives the screw 7 fixedly connected to it to rotate. Since the screw 7 is threadedly connected to the speaker enclosure 13, its axial movement during rotation pushes the front pressing plate 8. The force plate 9 attached to the outside of the pressing plate 8 is pushed during the sliding process, forcing the bracket 4 to swing around the pin to adjust its unfolding angle. During this process, the support plate 10 on the back of the pressing plate 8 is pressed against the back of the speaker module 1 to maintain stability, while the elastic plate 11 on the inner side of the bracket 4 continuously abuts against the module surface to provide cushioning. Finally, the unfolded end of the bracket 4 contacts the inner wall of the speaker enclosure 13 to form stable support. Through this linkage structure, the positioning mechanism accurately controls the angle of the bracket 4 to ensure that the speaker achieves anti-shake under the combined action of the enclosure fixation and external support.
