[0002] Audio devices are a collective term for various equipment or components used to process, transmit, and control audio signals. Audio devices generally include input devices, processing devices, transmission devices, storage devices, and output devices. Output devices generally consist of audio amplifiers and speakers. Audio amplifiers are used to amplify the power of audio signals to drive speakers to produce sufficiently loud sound. Audio amplifiers are divided into power amplifiers and preamplifiers. Power amplifiers are mainly responsible for providing sufficient power output, while preamplifiers are used for preliminary amplification and processing of audio signals, such as adjusting volume and tone. Speakers are used to convert electrical signals into sound signals and are the final output devices for audio playback. There are many types of speakers, including bookshelf speakers, floorstanding speakers, ceiling speakers, and headphones.

[0003] However, some audio devices generate strong vibrations when working, which can cause distortion in the system using the audio device and affect the user experience. Utility Model Content

[0004] The purpose of this application is to provide a vibration isolator and an audio device, which aims to solve the technical problem that vibrations generated by audio devices during operation can cause distortion in systems using audio devices, thus affecting the user experience.

[0005] To achieve the above objectives, according to one aspect of this application, a vibration isolator is provided. The vibration isolator is installed between an audio device and a base, used to decouple vibrations transmitted from the audio device to the base and separate vibrations transmitted from the external environment to the base from the audio device. The vibration isolator includes: a base module, an audio support module, an elastic damping module, and a load-bearing support module. The audio support module is installed on the base module, which is placed on the base, and serves to support the audio device. The elastic damping module is installed on the base module and located between the base module and the audio support module. The load-bearing support module is installed on the base module. The audio support module is movably coupled to the base module via a load-bearing support module, allowing the audio support module to move laterally relative to the base module. The audio support module has a pre-compression structure, which includes a pre-compression protrusion and a clearance recess. The audio support module abuts against the elastic damping module through the pre-compression protrusion, causing the elastic damping module to undergo elastic deformation to pre-compress it. The clearance recess is used to accommodate the deformed elastic damping module. When the audio support module moves laterally relative to the base module, the pre-compressed elastic damping module can continue to undergo elastic deformation to dampen the audio support module.

[0006] Optionally, the base module includes a base body, the upper end of which is provided with a receiving recess, the audio support module is at least partially inserted into the receiving recess, and the elastic damping module is located in the receiving recess; when the audio support module moves laterally relative to the base module, the contact area between the pre-compression structure and the pre-compression elastic damping module increases as the deformation of the elastic damping module increases.

[0007] Optionally, the elastic damping module includes an annular elastic damping member, the outer wall of which abuts against the inner wall of the receiving recess, and the audio support module is inserted inside the annular elastic damping member; the outer wall of the audio support module has a pre-compression structure, which maintains pre-compression contact with the inner wall of the annular elastic damping member after the audio support module is installed. When the audio support module moves laterally relative to the base module, the annular elastic damping member can undergo elastic deformation under the compression of the pre-compression structure to dampen the audio support module.

[0008] Optionally, the inner wall of the annular elastic damper gradually slopes outward from the first end to the second end of the annular elastic damper; the outer wall of the preload structure gradually slopes outward from the first end to the second end of the audio support module and abuts against the inner wall of the annular elastic damper; wherein, the first end of the audio support module is the end of the audio support module closest to the base body, and the first end of the annular elastic damper is the end of the annular elastic damper closest to the base body.

[0009] Optionally, the outer wall of the audio support module has a pre-compression structure, which includes multiple pre-compression protrusions arranged at intervals along the circumference of the audio support module.

[0010] Optionally, the pre-compression protrusion extends along the axial direction of the audio support module, and an outwardly convex pre-compression surface is formed on the outer side wall of the pre-compression protrusion. The outwardly convex pre-compression surface abuts against the elastic damping module to pre-compress the elastic damping module; and / or, the pre-compression structure also includes multiple clearance recesses, which are respectively disposed between two adjacent pre-compression protrusions to accommodate the deformed elastic damping module.

[0011] Optionally, the vibration isolator further includes a first anti-slip pad, which is mounted on the base module and at least partially protrudes from the side of the base module away from the audio support module, the base module being placed on the base via the first anti-slip pad; and / or, the vibration isolator further includes a second anti-slip pad, which is mounted on the audio support module and at least partially protrudes from the side of the audio support module away from the base module, the audio support module supporting the audio device via the second anti-slip pad.

[0012] Optionally, the load-bearing support module includes a rolling component, which is installed in the receiving recess and located between the first end of the audio support module and the bottom wall of the receiving recess. When the audio support module contacts the rolling component, the audio support module is tumbled to the base module through the rolling component.

[0013] Optionally, a first limiting structure is provided in the recess, and a second limiting structure is provided on the audio support module. When the audio support module moves away from the base module, the base module can restrict the movement of the support module away from the base module by cooperating with the first limiting structure and the second limiting structure.

[0014] According to another aspect of this application, an audio device is provided, the audio device including an audio unit, a substrate and a vibration isolator, the vibration isolator being installed between the audio unit and the substrate, and the vibration isolator being the aforementioned vibration isolator.

[0015] The beneficial effects of the vibration isolator provided in this application are as follows: Compared with the prior art, the vibration isolator provided in this application, by installing the elastic damping module on the base module and movably connecting the audio support module to the base module through the elastic damping module, allows the audio support module to be movably installed on the base module. Simultaneously, by setting the elastic damping module between the base module and the audio support module, the damping between the base module and the audio support module is increased, enabling the vibration isolator to dissipate sound through the elastic damping module during the lateral movement of the audio support module relative to the base module. The vibration energy transmitted from the frequency device to the audio support module is used to reduce the vibration of the audio support module and decouple the vibration transmitted from the audio device to the substrate. Furthermore, the audio support module pre-compresses the elastic damping module through the pre-compression protrusion of the pre-compression structure, causing the elastic damping module to undergo initial deformation. The yielding recess of the pre-compression structure accommodates the deformed elastic damping module, eliminating the assembly gap between the pre-compression protrusion and the elastic damping module, while reserving sufficient deformation space for the deformation of the elastic damping module. This improves the response sensitivity of the elastic damping module to small vibrations and ensures that the elastic damping module has a good vibration reduction effect.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] As described in the background section, audio devices are a collective term for various equipment or components used to process, transmit, and control audio signals. Audio devices generally include input devices, processing devices, transmission devices, storage devices, and output devices. Output devices typically consist of audio amplifiers and speakers. Audio amplifiers amplify the power of audio signals to drive speakers to produce sufficiently loud sound. Audio amplifiers are divided into power amplifiers and preamplifiers. Power amplifiers are primarily responsible for providing sufficient power output, while preamplifiers are used for preliminary amplification and processing of audio signals, such as adjusting volume and tone. Speakers convert electrical signals into sound signals and are the final output device for audio playback. There are many types of speakers, including bookshelf speakers, floorstanding speakers, ceiling speakers, and headphones. However, some audio devices generate strong vibrations during operation. These vibrations can cause distortion in the system using the audio device, affecting the user experience.

[0036] See Figures 1 to 7As shown, to solve the above problems, according to one aspect of this application, an embodiment of this application provides a vibration isolator. The vibration isolator is installed between an audio device and a base, used to decouple vibrations transmitted from the audio device to the base and separate vibrations transmitted from the external environment to the base from the audio device. The vibration isolator includes: a base module 10, an audio support module 20, an elastic damping module, and a load-bearing support module 40. The audio support module 20 is installed on the base module 10, which is placed on the base, and supports the audio device. The elastic damping module is installed on the base module 10 and located between the base module 10 and the audio support module 20. The load-bearing support module 40 is installed on the base. Module 10, the audio support module 20 is movably coupled to the base module 10 through the load-bearing support module 40, so that the audio support module 20 can move laterally relative to the base module 10; the audio support module 20 has a pre-compression structure 211, the pre-compression structure 211 includes a pre-compression protrusion 2111 and a clearance recess 2112, the audio support module 20 abuts against the elastic damping module through the pre-compression protrusion 2111, and causes the elastic damping module to undergo elastic deformation, so as to pre-compress the elastic damping module. The clearance recess 2112 is used to accommodate the deformed elastic damping module. When the audio support module 20 moves laterally relative to the base module 10, the pre-compressed elastic damping module can continue to undergo elastic deformation, so as to dampen the audio support module 20. The vibration isolator provided in this embodiment mounts an elastic damping module to the base module 10 and movably connects the audio support module 20 to the base module 10 via the elastic damping module. This allows the audio support module 20 to be movably mounted on the base module 10. Simultaneously, by setting the elastic damping module between the base module 10 and the audio support module 20, the damping between them is increased. This allows the vibration isolator to dissipate audio signals transmitted to the audio support module 20 via the elastic damping module during lateral movement of the audio support module 20 relative to the base module 10. The vibration energy on the 0 is reduced, thereby reducing the vibration of the audio support module 20 and decoupling the vibration transmitted from the audio device to the substrate. Furthermore, the audio support module 20 pre-compresses the elastic damping module through the pre-compression protrusion 2111 of the pre-compression structure 211, causing the elastic damping module to undergo initial deformation. The deformed elastic damping module is accommodated by the relief recess 2112 of the pre-compression structure 211. This eliminates the assembly gap between the pre-compression protrusion 2111 and the elastic damping module, while reserving sufficient deformation space for the deformation of the elastic damping module. This improves the response sensitivity of the elastic damping module to small vibrations and ensures that the elastic damping module has a good damping effect.

[0037] In some embodiments, when the audio support module 20 in this embodiment is not subjected to external force, the deformation of the elastic damping module caused by the pre-pressure of the pre-pressure protrusion 2111 is 0.4mm.

[0038] See Figure 2 As shown, in a specific embodiment, the base module 10 includes a base body 11, with a receiving recess 111 at its upper end. The audio support module 20 is at least partially inserted into the receiving recess 111, and the elastic damping module is located within the receiving recess 111. When the audio support module 20 moves laterally relative to the base module 10, the contact area between the pre-compression structure 211 and the pre-compression elastic damping module increases with the deformation of the elastic damping module. By placing the elastic damping module within the receiving recess 111, the vibration isolator can dissipate the vibration energy transmitted from the audio device to the audio support module 20 through the elastic deformation of the elastic damping module, thereby achieving vibration damping of the audio support module 20. It should be noted that in this embodiment, the contact area between the pre-compression structure 211 and the pre-compression elastic damping module increases as the deformation of the elastic damping module increases. This means that during the lateral movement of the audio support module 20 relative to the base module 10, the portion of the pre-compression elastic damping module that continues to deform enters the relief recess and fits against it, thereby causing the contact area between the pre-compression structure 211 and the pre-compression elastic damping module to increase as the deformation of the elastic damping module increases.

[0039] In some embodiments, the base body 11 provided in this embodiment is made of aluminum alloy.

[0040] In some other embodiments, the base body 11 in this embodiment is made of quenched martensitic stainless steel 420.

[0041] See Figure 2 , Figure 6 and Figure 7As shown, in a specific embodiment, the elastic damping module includes an annular elastic damping member 30. The outer wall of the annular elastic damping member 30 abuts against the inner wall of the receiving recess 111. The audio support module 20 is inserted into the annular elastic damping member 30. The outer wall of the audio support module 20 has a pre-compression structure 211. After the audio support module 20 is installed, the pre-compression structure 211 maintains pre-compression abutment against the inner wall of the annular elastic damping member 30. When the audio support module 20 moves laterally relative to the base module 10, the annular elastic damping member 30 can undergo elastic deformation under the compression of the pre-compression structure 211 to dampen the audio support module 20. By setting the elastic damping module provided in this embodiment as a ring component, and making the outer side wall of the ring elastic damping member 30 abut against the inner side wall of the receiving recess 111, the audio support module 20 is inserted inside the ring elastic damping member 30, and the inner side wall of the ring elastic damping member 30 abuts against the pre-compression structure 211, the vibration isolator provided in this embodiment can dissipate the vibration energy transmitted from the audio device to the audio support module 20 through the elastic deformation of the ring elastic damping member 30 during the lateral movement of the audio support module 20 relative to the base module 10 by the vibration energy of the audio component, thereby decoupling the lateral vibration transmitted from the audio device to the base, and thus achieving vibration reduction of the audio support module 20. At the same time, since the pre-compression structure 211 maintains pre-compression abutment with the inner side wall of the ring elastic damping member 30 through the pre-compression protrusion 2111 after the audio support module 20 is installed, the ring elastic damping member 30 can achieve an immediate response to vibration through the circumferentially distributed pre-compression.

[0042] It should be noted that in this embodiment, the pre-compression structure 211 causes the annular elastic damper 30 to undergo shear deformation by continuously compressing the inner wall of the annular elastic damper 30, thereby absorbing horizontal vibration energy.

[0043] In some embodiments, the material of the annular elastic damping member 30 in this embodiment is fumed silica gel.

[0044] In some embodiments, the silicone in this embodiment has a Shore hardness of 10.

[0045] In some embodiments, the upper end of the base body 11 provided in this embodiment has a first sidewall, the first sidewall is arranged to form a first recess, the annular elastic damping member 30 provided in this embodiment is installed in the first recess, the bottom wall of the annular elastic damping member 30 is engaged with the bottom wall of the first recess, and the inner sidewall of the first recess is engaged with the outer sidewall of the annular elastic damping member 30.

[0046] In some embodiments, the outer wall of the preload structure 211 provided in this embodiment is adapted to the inner wall of the annular elastic damper 30.

[0047] In some embodiments, the first sidewall provided in this embodiment is annular.

[0048] In some embodiments, a second recess is provided on the bottom wall of the first recess provided in this embodiment, and the second recess and the first recess together form a receiving recess 111.

[0049] In some embodiments, the lateral direction provided in this embodiment is a direction perpendicular to the height direction of the base body 11. Of course, in other embodiments, the lateral direction provided in this embodiment can also be other directions.

[0050] See Figure 2 , Figures 4 to 7 As shown, in a specific embodiment, the inner wall of the annular elastic damper 30 gradually slopes radially outward from the first end to the second end of the annular elastic damper 30; the outer wall of the pre-compression structure 211 gradually slopes radially outward from the first end to the second end of the audio support module 20 and abuts against the inner wall of the annular elastic damper 30; wherein, the first end of the audio support module 20 is the end of the audio support module 20 closest to the base body 11, and the first end of the annular elastic damper 30 is the end of the annular elastic damper 30 closest to the base body 11. By setting the inner wall of the annular elastic damper 30 in this embodiment to gradually tilt outward from the first end to the second end of the annular elastic damper 30, and setting the outer wall of the preload structure 211 to gradually tilt outward from the first end to the second end of the audio support module 20, the contact area between the annular elastic damper 30 and the audio support module 20 can be increased, so that the vibration energy transmitted to the audio support module 20 can be fully consumed.

[0051] See Figures 4 to 7As shown, in a specific embodiment, the outer wall of the audio support module 20 has a pre-compression structure 211. The pre-compression structure 211 includes multiple pre-compression protrusions 2111, which are arranged at intervals along the circumference of the audio support module 20. By arranging the multiple pre-compression protrusions 2111 at intervals along the circumference of the audio support module 20, a discrete contact area can be formed between the pre-compression structure 211 and the elastic damping module. This allows the pre-compression structure 211 to apply a uniformly distributed radial pre-compression force to the elastic damping module, ensuring sufficient frictional damping while avoiding stress concentration on continuous contact surfaces. Furthermore, each pre-compression protrusion 2111 acts independently on the elastic damping module, enabling the elastic damping module to form a periodically compressed deformation zone, preventing over-compression of the elastic damping module. The characteristic of circumferential discontinuous contact allows vibration energy to be fully dissipated, significantly improving vibration isolation efficiency.

[0052] See Figures 4 to 7 As shown, in a specific embodiment, the pre-compression protrusion 2111 extends along the axial direction of the audio support module 20. An outwardly convex pre-compression surface 21111 is formed on the outer wall of the pre-compression protrusion 21111, which abuts against the elastic damping module to pre-compress it. By setting the pre-compression protrusion 2111 to abut against the elastic damping module via the outwardly convex pre-compression surface 21111, a smooth transition of contact stress during the pre-compression process can be ensured, avoiding fatigue damage to the elastic material of the elastic damping module caused by sudden changes in local stress. It should be noted that in this embodiment, both the audio bearing module and the elastic damping module extend longitudinally. The axial direction of both the audio bearing module and the elastic damping module is parallel to the longitudinal direction, and the radial direction is perpendicular to the longitudinal direction. In this embodiment, the longitudinal direction is perpendicular to the transverse direction; however, in other embodiments, the transverse direction provided in this embodiment can also be other directions.

[0053] In some embodiments, the convex preload surface 21111 in this embodiment is a convex arc-shaped surface. Setting the convex preload surface 21111 as a convex arc-shaped surface allows the preload applied to the elastic damping module by the preload protrusion 2111 to be gradually distributed along the contact interface, forming a smooth pressure gradient. The arc-shaped contour of the convex arc-shaped surface and the contact line of the elastic damping module naturally expand as the pressure increases, ensuring a smooth contact in the initial preload stage and maintaining stable damping characteristics through the increased contact area when the load increases. Simultaneously, the geometric characteristics of the curved surface effectively avoid edge stress concentration, making the elastic material deformation of the elastic damping module more uniform. Furthermore, the arc-shaped contact surface can generate multi-directional frictional forces, significantly improving the energy dissipation efficiency of the vibration isolator. Of course, in other embodiments, the convex preload surface 21111 in this embodiment can also be of other shapes.

[0054] See Figures 4 to 7 As shown, in a specific embodiment, the pre-compression structure 211 in this embodiment further includes a plurality of clearance recesses 2112, which are respectively disposed between two adjacent pre-compression protrusions 2111 to accommodate the elastic damping module after deformation. By providing a clearance recess 2112 between two adjacent pre-compression protrusions 2111, a controllable deformation buffer can be provided for the elastic vibration damping module. When the pre-compression protrusion 2111 applies radial pressure to the elastic vibration damping module, the clearance recess 2112 allows the compressed material to extend freely in the circumferential direction, avoiding stress concentration caused by excessive material compression. At the same time, it provides sufficient deformation space for the elastic vibration damping module. Meanwhile, the clearance recess 2112 can also enable the elastic vibration damping module to form a regular deformation gradient zone, enhancing the energy dissipation efficiency of the elastic vibration damping module. Under the premise of ensuring necessary pre-compression, it reduces the risk of creep of the elastic material of the elastic vibration damping module and extends the service life of the elastic vibration damping module. At the same time, the air channel formed by the clearance recess 2112 helps to suppress the air cushion effect during vibration and improve the response speed of the vibration isolator to transient impacts.

[0055] In some embodiments, the recessed portion 2112 provided in this embodiment has a concave recessed surface 21121. The concave recessed surface 21121 smoothly transitions with the two adjacent convex preloaded surfaces 21111. The multiple concave recessed surfaces 21121 and the multiple convex preloaded surfaces 21111 together form the outer wall of the preloaded structure 211. In this embodiment, the convex preloaded surfaces 21111 can provide the main preloaded contact point and generate the necessary damping force, while the concave recessed surface 21121 can establish a smooth stress transition zone between adjacent pressure zones, avoiding material fatigue caused by local stress concentration. While maintaining the overall preloaded stiffness, it significantly improves the efficiency of vibration energy dissipation.

[0056] In some embodiments, the concave yielding surface 21121 provided in this embodiment is a concave arc-shaped surface. The concave yielding surface 21121 smoothly transitions with the two adjacent convex preloading surfaces 21111. The multiple concave yielding surfaces 21121 and the multiple convex preloading surfaces 21111 together form the outer wall of the preloading structure 211. In this embodiment, the convex preloading surface 21111 can provide the main preloading contact point and generate the necessary damping force, while the concave yielding surface 21121 can establish a smooth stress transition zone between adjacent pressure zones, avoiding material fatigue caused by local stress concentration. While maintaining the overall preloading stiffness, it significantly improves the efficiency of vibration energy dissipation.

[0057] In some embodiments, the concave clearance surface 21121 provided in this embodiment is a concave arc-shaped surface. By setting the concave clearance surface 21121 as a concave arc-shaped surface, a smooth stress transition zone can be formed between adjacent pre-compression protrusions 2111. Its continuous curved profile allows the compression deformation of the elastic damping module to exhibit a progressive characteristic. The arc-shaped concave surface provides uniform extension space for the compressed material, effectively avoiding local stress concentration caused by sharp corner contact. Of course, in other embodiments, the concave clearance surface 21121 in this embodiment can also be of other shapes.

[0058] In some embodiments, the multiple concave arc surfaces and multiple convex arc surfaces provided in this embodiment together form a wave-shaped preloading surface, which forms the outer wall of the preloading structure 211. The wave-shaped preloading surface provided in this embodiment is composed of periodically alternating convex arc surfaces and concave arc surfaces, forming a dynamic contact interface with continuous curvature changes. The convex arc surfaces provide precise preloading contact points and establish stable initial damping forces, while the concave arc surfaces form a buffer release zone, providing controllable space for the deformation of the elastic material. Through its continuous curvature change characteristics, stress concentration can be effectively avoided.

[0059] In some embodiments, along the circumferential direction of the audio support module 20, the width of the convex pre-compression surface 21111 in this embodiment is smaller than the width of the concave clearance surface 21121. The circumferential direction of the audio support module 20 refers to the circumferential direction of the audio support module 20 perpendicular to the axial direction.

[0060] In some embodiments, the vibration isolator in this embodiment further includes a first anti-slip pad 50. The first anti-slip pad 50 is mounted on the base module 10 and at least partially protrudes from the side of the base module 10 away from the audio support module 20. The base module 10 is placed on the base body via the first anti-slip pad 50. By providing the first anti-slip pad 50 on the base module 10 and making the first anti-slip pad 50 at least partially protrude from the side of the base module 10 away from the audio support module 20, the base module 10 provided in this embodiment can be placed on the base body via the first anti-slip pad 50. By providing the first anti-slip pad 50, the friction between the vibration isolator provided in this embodiment and the base body can be effectively increased, thereby preventing the vibration isolator from sliding on the base body.

[0061] In some embodiments, the vibration isolator in this embodiment further includes a second anti-slip pad 60. The second anti-slip pad 60 is mounted on the audio support module 20 and at least partially protrudes from the side of the audio support module 20 away from the base module 10. The audio support module 20 supports the audio device via the second anti-slip pad 60. By providing the second anti-slip pad 60 on the audio support module 20 and making the second anti-slip device at least partially protrude from the side of the audio support module 20 away from the base module 10, the audio support module 20 provided in this embodiment can support the audio device via the second anti-slip pad 60. By providing the second anti-slip pad 60, the friction between the vibration isolator and the audio device provided in this embodiment can be effectively increased, thereby preventing the audio device from sliding on the vibration isolator.

[0062] In some embodiments, a first mounting groove is provided on the side of the base module 10 away from the audio support module 20 provided in this embodiment. The first anti-slip pad 50 provided in this embodiment is installed in the first mounting groove and at least partially protrudes from the first mounting groove.

[0063] In some embodiments, the first anti-slip pad 50 provided in this embodiment is fixedly connected to the base module 10 by adhesive bonding.

[0064] In some embodiments, the material of the first anti-slip pad 50 provided in this embodiment is an elastic material, such as rubber or other elastic materials.

[0065] In some embodiments, the audio support module 20 provided in this embodiment has a second mounting groove on the side away from the base module 10.

[0066] In some embodiments, the second anti-slip pad 60 provided in this embodiment is fixedly connected to the audio support module 20 by adhesive bonding.

[0067] In some embodiments, the material of the second anti-slip pad 60 provided in this embodiment is an elastic material, such as rubber or other elastic materials.

[0068] See Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, in a specific embodiment, the load-bearing support module 40 includes a rolling component 41. The rolling component 41 is installed within the receiving recess 111 and located between the first end of the audio support module 20 and the bottom wall of the receiving recess 111. When the audio support module 20 contacts the rolling component 41, the audio support module 20 is rolledly connected to the base module 10 through the rolling component 41. By setting the rolling component 41, a rolling contact interface can be formed between the audio support module 20 and the base module 10, transforming traditional sliding friction into rolling friction. This significantly reduces the motion resistance of the audio support module 20, enabling it to respond sensitively to minute vibrations. While providing reliable mechanical support, it retains the dynamic adjustment capability of the elastic damping module, allowing the vibration isolator to maintain a good damping effect under various load conditions.

[0069] See Figure 2 As shown, in a specific embodiment, a first limiting structure 4231 is provided within the receiving recess 111, and a second limiting structure 221 is provided on the audio support module 20. When the audio support module 20 moves away from the base module 10, the base module 10 can restrict the movement of the support module away from the base module 10 by cooperating with the first limiting structure 4231 and the second limiting structure 221. By providing the first limiting structure 4231 within the receiving recess 111 and the second limiting structure 221 on the audio support module 20, the base module 10 provided in this embodiment can limit the movement of the audio support module 20 away from the base module 10 by cooperating with the first limiting structure 4231 and the second limiting structure 221.

Furthermore, the radial direction of the support cover plate 21 is perpendicular to the height direction of the base module 10.

[0074] In some embodiments, the diameter of the end of the support cover plate 21 away from the limiting member provided in this embodiment is greater than the maximum diameter of the pre-compression structure 211.

[0075] In some embodiments, the support cover plate 21 provided in this embodiment is connected to the limiting member by threaded fasteners.

[0077] In some embodiments, the first connecting bolt, the first through hole and the first threaded hole provided in this embodiment are all multiple. The multiple first through holes provided in this embodiment are arranged at intervals along the circumference of the support cover plate 21.

A limiting bolt 423 is provided on the side of the limiting shaft assembly 42 away from the base body 11. The limiting bolt 423 is screwed into the end of the limiting shaft assembly 42 through the inner hole of the annular limiting member 22.

[0080] In some embodiments, the limiting bolt 423 and the limiting flange provided in this embodiment have a movable gap in the lateral direction, so that the audio support module 20 can move relative to the base module 10 in the lateral direction.

[0081] In some embodiments, the rolling assembly 41 provided in this embodiment includes a silicon carbide ceramic bead 411 and a retainer 412. The retainer 412 provided in this embodiment is installed in the receiving recess 111 and is located between the first end of the audio support module 20 and the bottom wall of the receiving recess 111. The retainer 412 extends laterally and is provided with a mounting hole extending longitudinally. The silicon carbide ceramic bead 411 is rotatably installed in the mounting hole. The upper end of the silicon carbide ceramic bead 411 protrudes at least partially from the side of the retainer 412 near the audio support module 20 and abuts against the first end of the audio support module 20. The lower end of the silicon carbide ceramic bead 411 abuts against the bottom wall of the receiving recess 111.

[0085] In some embodiments, the silicon carbide ceramic bead 411 provided in this embodiment is a spherical component.

[0086] In some embodiments, the limiting shaft assembly 42 in this embodiment includes a limiting shaft body 421 and an elastic buffer sleeve 422. The limiting shaft body 421 is fixedly installed in the receiving recess 111, and the elastic buffer sleeve 422 is sleeved on the limiting shaft body 421. The retainer 412 is provided with a bearing mounting hole, and the retainer 412 is sleeved on the elastic buffer sleeve 422 through the bearing mounting hole. The outer side wall of the elastic buffer sleeve 422 cooperates with the inner side wall of the bearing mounting hole, and the inner side wall of the elastic buffer sleeve 422 cooperates with the outer side wall of the limiting shaft body 421. Through the elastic deformation of the elastic buffer sleeve 422, the retainer 412 is movably installed in the receiving recess 111. The movable installation of the retainer 412 in the receiving recess 111 facilitates the rolling of the silicon carbide ceramic bead 411, thereby further reducing the movement resistance of the audio support module 20 and enabling the audio support module 20 to respond sensitively to small vibrations.

[0087] It should be noted that, in this embodiment, the end of the limiting shaft body 421 away from the base body is provided with a limiting threaded hole, and the limiting bolt 423 is screwed into the limiting threaded hole.

[0088] In some embodiments, a positioning recess is provided on the bottom wall of the receiving recess 111 in this embodiment, and a positioning protrusion is provided at one end of the limiting shaft body 421 near the base body. The positioning protrusion is adapted to the positioning recess, and the limiting shaft body 421 can be quickly positioned in the receiving recess 111 through the cooperation of the positioning protrusion and the positioning recess.

[0089] In some embodiments, the limiting shaft body 421 and the base body are fixedly connected by threaded fasteners.

[0090] In some embodiments, the audio support module 20 provided in this embodiment can move laterally relative to the base module 10 through the silicon carbide ceramic bead 411 assembly. During the process of the audio support module 20 moving laterally relative to the base module 10 through the vibration energy of the audio device, the movement of the audio support module 20 can consume the vibration energy transmitted from the audio device to the audio support module 20 through the elastic deformation of the annular elastic damping member 30, thereby decoupling the lateral vibration transmitted from the audio device to the substrate.

[0091] According to another aspect of this application, an audio device is provided, the audio device including an audio unit, a substrate and a vibration isolator, the vibration isolator being installed between the audio unit and the substrate, and the vibration isolator being the aforementioned vibration isolator.

[0092] In some embodiments, the audio device provided in this embodiment includes multiple vibration isolators, and the audio device provided in this embodiment is supported by multiple vibration isolators simultaneously.

[0093] In some embodiments, the substrate provided in this embodiment is a support device capable of supporting an audio device. Of course, in other embodiments, the substrate provided in this embodiment may also be formed from the ground.

[0094] In summary, implementing the vibration isolator and audio equipment provided in this embodiment has at least the following beneficial technical effects: The vibration isolator provided in this embodiment, by installing the elastic damping module on the base module 10 and movably connecting the audio support module 20 to the base module 10 through the elastic damping module, allows the audio support module 20 to be movably installed on the base module 10. Simultaneously, by providing the elastic damping module between the base module 10 and the audio support module 20, the damping between them is increased, enabling the vibration isolator to absorb the vibration during the lateral movement of the audio support module 20 relative to the base module 10 through elastic damping. The module consumes the vibration energy transmitted from the audio device to the audio support module 20, thereby reducing the vibration of the audio support module 20 and decoupling the vibration transmitted from the audio device to the substrate. Furthermore, the audio support module 20 pre-compresses the elastic damping module through the pre-compression protrusion 2111 of the pre-compression structure 211, causing the elastic damping module to undergo initial deformation. The yielding recess 2112 of the pre-compression structure 211 accommodates the deformed elastic damping module, eliminating the assembly gap between the pre-compression protrusion 2111 and the elastic damping module, while reserving sufficient deformation space for the deformation of the elastic damping module, improving the response sensitivity of the elastic damping module to small vibrations, and ensuring that the elastic damping module has a good damping effect.

[0095] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
