[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 typically consist of audio amplifiers and speakers. Audio amplifiers amplify the power of audio signals to drive the 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, and ceiling speakers. In existing technologies, vibration isolation between the audio device and its external environment is generally achieved by placing a vibration isolator between the audio device and the external environment.

[0010] Optionally, the base portion also includes a base plate module, which is placed on the base body, and at least one of the arrangement support module and the swing arm support module is detachably mounted on the base plate module.
[0011] Optionally, the base plate module includes a base plate body and a support foot assembly.

At the same time, since the swing arm support group is detachably installed on the arrangement support module, and the arrangement support module has various sizes and specifications, the vibration isolation device provided in this application can increase or decrease the maximum arrangement spacing of the swing arm support modules in the first direction and / or the second direction by replacing the arrangement support modules of different sizes and specifications, thereby forming vibration isolation devices of different sizes and specifications to adapt to audio devices of different sizes. Since vibration isolation devices of different sizes and specifications can share the same swing arm support module, the production cost of vibration isolation devices of different sizes and specifications can be effectively reduced.

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.
[0032] As described in the background section, an audio device is a general term for various devices 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 the 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, and ceiling speakers. In existing technologies, vibration isolation between the audio device and its external environment is generally achieved by placing vibration isolators between the audio device and the external environment. However, to provide vibration isolation for audio devices of different sizes, it is often necessary to produce vibration isolation devices of various sizes and specifications, resulting in high production costs.
[0033] See Figures 1 to 8As shown, to solve the above problems, according to one aspect of this application, an embodiment of this application provides a vibration isolation device. The vibration isolation device 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 isolation device includes: a base portion 10 and an audio support portion 20, wherein the audio support portion 20 is installed on the base portion 10 and is adapted to the size of the base portion 10 to support the audio device, and the base portion 10 is placed on the base; the base portion 10 includes a layout support module 11 and a swing arm support assembly 12, the layout support module 11 has multiple size specifications, and the swing arm support assembly 12 is selectively installed on one size of the layout support module 11 and is detachable from the corresponding layout support module 11. The connection is as follows: the swing arm support assembly 12 includes multiple swing arm support modules 121, each swing arm support module 121 is provided with a first positioning structure, and the arrangement support module 11 is provided with multiple second positioning structures arranged at intervals along a first direction and / or a second direction. The swing arm support module 121 is positioned on the arrangement support module 11 through the cooperation of the first positioning structure and the second positioning structure. The audio support part 20 is installed on multiple swing arm support modules 121 and can be translated relative to the base part 10 in a direction perpendicular to the swing axis of the swing arm support module 121. The first direction is a horizontal direction parallel to the swing axis, the second direction is a horizontal direction perpendicular to the first direction, and the maximum arrangement spacing of the second positioning structures in the first direction and / or the second direction is the size specification of the arrangement support module. The vibration isolation device provided in this embodiment installs multiple swing arm support modules 121 spaced apart on the arrangement support module 11, and simultaneously installs the audio support part 20 on the multiple swing arm support modules 121. This allows the vibration energy transmitted from the audio device to the audio support part 20 to be converted into translational motion of the audio support part 20 perpendicular to the swing axis of the swing arm support module 121. Thus, the vibration isolation device can dissipate the vibration energy transmitted from the audio device to the audio support part 20 through the movement of the swing arm support modules 121, thereby achieving vibration reduction of the audio support part 20 and decoupling the vibration transmitted from the audio device to the substrate. Meanwhile, since the swing arm support assembly 12 is detachably installed on the arrangement support module 11, and the arrangement support module 11 has various sizes, the vibration isolation device provided in this embodiment can increase or decrease the maximum arrangement spacing of the swing arm support module 121 in the first direction and / or the second direction by replacing the arrangement support module 11 of different sizes, thereby forming vibration isolation devices of different sizes to adapt to audio devices of different sizes. Since vibration isolation devices of different sizes can share the swing arm support module 121, the production cost of vibration isolation devices of different sizes can be effectively reduced.The size matching between the audio support 20 and the base 10 refers to the projection of the audio support 20 onto the base 10, which can cover the installation area of the swing arm support module 121 that participates in the support, so that the audio support 20 can be stably supported and the vibration energy can be fully dissipated through the swing arm support module 121.
[0034] It should be noted that when the multiple second positioning structures in this embodiment are arranged at intervals only along the first direction, the audio support portion 20 installed on the swing arm support module 121 has both rotational degrees of freedom around the swing axis and translational degrees of freedom perpendicular to the swing axis; when the second positioning structures are arranged at intervals along the second direction or simultaneously along the first and second directions, the motion degrees of freedom of the audio support portion 20 are constrained to retain only the translational degrees of freedom perpendicular to the swing axis, and its rotational degrees of freedom are effectively suppressed due to the spatial constraint of the swing arm support module 121.
[0035] It is understandable that by setting a first positioning structure on the swing arm support module 121 and setting multiple second positioning structures at intervals on the arrangement support module 11, each swing arm support module 121 can be quickly positioned and assembled on the arrangement support module 11 through the cooperation of the first positioning structure and the second positioning structure, thereby effectively reducing the production cost of the vibration isolation device.
[0036] In some embodiments, the first positioning structure in this embodiment includes a first positioning groove, and the second positioning structure in this embodiment includes a first positioning protrusion. The first positioning groove and the first positioning protrusion are adapted to each other, and the swing arm support module 121 can be quickly positioned on the arrangement support module 11 through the sliding engagement of the first positioning groove and the first positioning protrusion. Through the sliding engagement structure of the first positioning groove and the first positioning protrusion, the swing arm support module 121 can be quickly and accurately positioned on the arrangement support module 11, which improves the assembly efficiency of the swing arm support module 121 while ensuring that the vibration isolation device has good assembly accuracy and structural stability.
[0037] In some embodiments, the arrangement support module 11 in this embodiment is made of aluminum alloy. Of course, in other embodiments, the arrangement support module 11 in this embodiment can also be made of other metal materials.
[0038] See Figure 2 , Figure 7 and Figure 8As shown, in a specific embodiment, the swing arm support module 121 includes a swing arm mounting assembly 1211, a support assembly 1212, and a swing arm assembly 1213. The swing arm mounting assembly 1211 is provided with a first positioning structure. The support assembly 1212 is mounted on the audio support part 20. The two ends of the swing arm assembly 1213 are pivotally connected to the swing arm mounting assembly 1211 and the support assembly 1212, respectively. The pivot axis between the support assembly 1212 and the swing arm assembly 1213 is located below the pivot axis between the swing arm mounting assembly 1211 and the swing arm assembly 1213, and is parallel to the pivot axis between the swing arm mounting assembly 1211 and the swing arm assembly 1213. The pivot axis between the support assembly 1212 and the swing arm assembly 1213 and the pivot axis between the swing arm mounting assembly 1211 and the swing arm assembly 1213 form the swing axis of the swing arm support module 121. By setting the pivot axis between the support assembly 1212 and the swing arm assembly 1213 to be below the pivot axis between the swing arm mounting assembly 1211 and the swing arm assembly 1213, and parallel to the pivot axis between the swing arm mounting assembly 1211 and the swing arm assembly 1213, the vibration energy obtained by the audio support 20 can be efficiently converted into the swing motion of the swing arm assembly 1213, ensuring that the vibration energy can be directionally converted in a direction perpendicular to the swing axis, thereby achieving effective vibration reduction of the audio support 20. In addition, setting the pivot axis between the support assembly 1212 and the swing arm assembly 1213 to be below the pivot axis between the swing arm mounting assembly 1211 and the swing arm assembly 1213 also enables the swing arm assembly 1213 to have a certain gravity self-resetting capability, so that the swing arm assembly 1213 can automatically return to its original position by gravity after the vibration stops, thereby effectively improving the working stability of the vibration isolation device.
[0039] In some embodiments, the swing arm mounting assembly 1211 and the support assembly 1212 in this embodiment are made of aluminum alloy. Of course, in other embodiments, the swing arm mounting assembly 1211 and the support assembly 1212 in this embodiment may also be made of other metal materials.
[0040] See Figure 3 and Figures 4 to 8As shown, in a specific embodiment, the swing arm assembly 1213 includes a swing arm body 12131, a first needle roller bearing 12132, and a second needle roller bearing 12133. A first mounting hole and a second mounting hole are respectively provided at both ends of the swing arm body 12131. The first needle roller bearing 12132 is mounted in the first mounting hole, and the outer ring of the first needle roller bearing 12132 mates with the inner wall of the first mounting hole. The second needle roller bearing 12133 is mounted in the second mounting hole, and the second needle roller bearing 12132... The outer ring of 33 mates with the inner sidewall of the second mounting hole; the swing arm mounting assembly 1211 is provided with a first pivot shaft 121121, which passes through the first mounting hole, and the outer sidewall of the first pivot shaft 121121 mates with the inner ring of the first needle roller bearing 12132; the support assembly 1212 is provided with a second pivot shaft 12121, which passes through the second mounting hole, and the outer sidewall of the second pivot shaft 12121 mates with the inner ring of the second needle roller bearing 12133. By setting a first needle roller bearing 12132 between the first mounting hole and the first pivot shaft 121121, and setting a second needle roller bearing 12133 between the second mounting hole and the second pivot shaft 12121, the swing arm module can convert the sliding friction between the first pivot shaft 121121 and the first mounting hole into rolling friction within the first needle roller bearing 12132 through the first needle roller bearing 12132, and convert the sliding friction between the second pivot shaft 12121 and the second mounting hole into rolling friction within the second needle roller bearing 12133 through the second needle roller bearing 12133. This reduces the swing resistance of the swing arm assembly 1213 and improves the vibration response sensitivity of the swing arm assembly 1213.
[0041] In some embodiments, the swing arm body 12131 in this embodiment is made of stainless steel. Of course, in other embodiments, the swing arm body 12131 in this embodiment can also be made of other metal materials.
[0042] In some embodiments, the swing arm assembly 1213 further includes a first retaining ring and a second retaining ring. The first retaining ring is installed in the first mounting hole to limit the axial movement of the outer ring of the first needle roller bearing 12132. The second retaining ring is installed in the second mounting hole to limit the axial movement of the outer ring of the second needle roller bearing 12133. By respectively providing the first retaining ring and the second retaining ring in the first and second mounting holes, the axial displacement of the outer rings of the first needle roller bearing 12132 and the second needle roller bearing 12133 can be effectively limited, ensuring that the first needle roller bearing 12132 and the second needle roller bearing 12133 have stable working positions under vibration conditions, thus enabling the swing arm assembly 1213 to have good motion accuracy and service life.
[0043] In some embodiments, the swing arm assembly 1213 of this embodiment further includes a first connecting screw, a second connecting screw, a first washer, and a second washer. In this embodiment, the end of the first pivot shaft 121121 is provided with a first connecting threaded hole extending axially therefrom, and the end of the second pivot shaft 12121 is provided with a second connecting threaded hole extending axially therefrom. In this embodiment, the first connecting screw is screwed into the first connecting threaded hole, and the first washer is clamped between the first pivot shaft 121121 and the first connecting screw to limit the axial movement of the inner ring of the first needle roller bearing 12132. The second connecting screw is screwed into the second connecting threaded hole, and the second washer is clamped between the second pivot shaft 12121 and the second connecting screw to limit the axial movement of the inner ring of the second needle roller bearing 12133. The combination of the first connecting screw and the first washer enables precise axial positioning of the inner ring of the first needle roller bearing 12132, effectively preventing axial movement of the first needle roller bearing 12132 under vibration conditions. Similarly, the combination of the second connecting screw and the second washer enables precise axial positioning of the inner ring of the second needle roller bearing 12133, effectively preventing axial movement of the second needle roller bearing 12133 under vibration conditions. This ensures that both the first and second needle roller bearings 12132 and 12133 have stable working positions under vibration conditions, allowing the swing arm assembly 1213 to have good motion accuracy and service life.
[0044] In some embodiments, the swing arm mounting assembly 1211 includes a support body 12111 and a swing arm mounting seat 12112. The support body 12111 is provided with a first insertion groove, and the swing arm mounting seat 12112 is provided with a first insertion protrusion. The swing arm mounting seat 12112 is quickly positioned on the support body 12111 through the cooperation of the first insertion protrusion and the first insertion groove. A first positioning structure is provided on the support body 12111, and a first pivot shaft 121121 is provided on the swing arm mounting seat 12112. Through the quick-fit structure of the first insertion groove and the first insertion protrusion, the swing arm mounting seat 12112 can be quickly and accurately positioned on the support body 12111. Furthermore, the separate arrangement of the support body 12111 and the swing arm mounting seat 12112 also allows the swing arm mounting seat 12112 to be maintained and replaced independently, reducing the maintenance cost of the vibration isolation device.
[0045] In some embodiments, the support body 12111 and the swing arm mounting base 12112 in this embodiment are detachably connected by threaded fasteners. This detachable connection ensures a stable and reliable connection between the support body 12111 and the swing arm mounting base 12112, and also facilitates independent disassembly and maintenance of the swing arm mounting base 12112, effectively reducing the maintenance cost of the vibration isolation device. Of course, in other embodiments, the support body 12111 and the swing arm mounting base 12112 in this embodiment can also be connected by other detachable methods such as magnetic connection or snap-fit connection.
[0046] See Figure 4 and Figure 5 As shown, in a specific embodiment, the layout support module 11 includes a first layout support component 111 and two second layout support components 112. The two second layout support components 112 are detachably installed on opposite sides of the first layout support component 111 in a first direction. The second layout support components 112 extend along a second direction, and each of the opposite ends of the second layout support components 112 in the second direction is provided with at least one second positioning structure. It should be noted that the first layout support component 111 in this embodiment has various sizes; replacing the first layout support component 111 with different sizes can adjust the spacing between the two second layout support components 112 in the first direction. Similarly, the second layout support components 112 have various sizes; replacing the second layout support component 112 with different sizes can adjust the spacing between the opposite ends of the corresponding second layout support components 112 in the second direction. It is understood that in this embodiment, the size of the first arrangement support assembly 111 is the spacing between the two opposite sides of the first arrangement support assembly 111 in the first direction, and the size of the second arrangement support assembly 112 is the spacing between the two opposite ends of the second arrangement support assembly 112 in the second direction. Since the two second arrangement support assemblies 112 are detachably installed on the opposite sides of the first arrangement support assembly 111, and the sizes of the first arrangement support assembly 111 and the second arrangement support assembly 112 are adjustable, the arrangement support module 11 provided in this embodiment can increase or decrease the spacing between the second positioning structures at the ends of the second arrangement support assembly 112 by replacing the first arrangement support assembly 111 and the second arrangement support assembly 112 with different sizes, thereby obtaining arrangement support modules 11 with different sizes. Arrangement support modules 11 with different sizes can cooperate with the adjustment of the swing arm support module 121 to form vibration isolation devices with different sizes to adapt to audio devices of different sizes. The spacing between the second positioning structures refers to the spacing between the second positioning structures located at different ends.
[0047] In some embodiments, the first arrangement support assembly 111 in this embodiment includes an X-shaped bracket. The X-shaped bracket in this embodiment has a first connecting end, a second connecting end, a third connecting end, and a fourth connecting end on opposite sides in a first direction, wherein the first connecting end and the second connecting end are disposed on the same side, and the third connecting end and the fourth connecting end are disposed on the same side. A second insertion protrusion is provided on the first connecting end, the second connecting end, the third connecting end, and the fourth connecting end. The second arrangement support assembly 112 in this embodiment includes an arrangement positioning plate. A plurality of second insertion slots are provided on the side of the arrangement positioning plate near the X-shaped bracket. The plurality of second insertion slots are spaced apart along the extension direction of the arrangement positioning plate, and the positions of at least two second insertion slots correspond to the positions of the first connecting end and the second connecting end, or the positions of at least two second insertion slots correspond to the positions of the third connecting end and the fourth connecting end, respectively. The arrangement positioning plate is quickly positioned on the side of the X-shaped bracket through the cooperation of the second insertion slots and the second insertion protrusions, wherein the arrangement positioning plate extends along a second direction. By engaging the second insertion protrusion with the second insertion slot, the positioning plate can be quickly positioned and securely connected to the side of the X-shaped bracket, ensuring precise adjustment of the distribution density of the swing arm support module 121, while significantly improving the assembly efficiency and structural integrity of the vibration isolation device. Of course, in other embodiments, the first arrangement support component 111 in this embodiment can also be a Y-shaped bracket, an H-shaped bracket, or other bracket structures.
[0048] In some embodiments, the first, second, third, and fourth connecting ends of this embodiment are each provided with a plurality of second insertion protrusions. These protrusions on the same connecting end are spaced apart along the extension direction of the corresponding branches of the X-shaped bracket. The second insertion protrusion furthest from the center of the X-shaped bracket is the effective second insertion protrusion, which is used to mate with the second insertion slot. By cutting the connecting end of the X-shaped bracket, the second insertion protrusions at corresponding positions can form effective second insertion protrusions, thus obtaining an X-shaped bracket of the corresponding size. By providing spaced second insertion protrusions at each connecting end of the X-shaped bracket, and using the furthest second insertion protrusion as the effective connection point, the X-shaped bracket can be manufactured in different sizes by cutting and adjusting each connecting end. This significantly improves the versatility and ease of maintenance of the vibration isolation device while ensuring rapid assembly of the X-shaped bracket with the positioning plate.
[0049] In one specific embodiment, the second arrangement support assembly 1212 in this embodiment is provided with a plurality of second positioning structures at both ends of opposite sides in the second direction, and the plurality of second positioning structures are arranged at intervals along the second direction. By providing a plurality of second positioning structures arranged at intervals along the second direction at the ends of the second arrangement support assembly 1212, the swing arm support module 121 can adjust its relative position in the second direction by cooperating with the second positioning structures at different positions.
[0050] In some embodiments, the arrangement positioning plate in this embodiment has multiple first positioning protrusions at both ends. These protrusions at the same end are spaced apart along the extending direction of the arrangement positioning plate. The first positioning protrusion furthest from the center of the arrangement positioning plate is the effective first positioning protrusion, which engages with the first positioning groove. By cutting the end of the arrangement positioning plate, the first positioning protrusions at corresponding positions can form effective first positioning protrusions, thus obtaining an arrangement positioning plate of the corresponding size. By providing spaced first positioning protrusions at both ends of the arrangement positioning plate and using the furthest first positioning protrusion as an effective connection point, the arrangement positioning plate can be manufactured in different sizes by cutting and adjusting its ends. This ensures rapid assembly of the arrangement positioning plate with the swing arm support module 121 while significantly improving the versatility and ease of maintenance of the vibration isolation device.
[0051] See Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, in a specific embodiment, the base portion 10 further includes a base plate module 13, which is placed on the base. At least one of the arrangement support module 11 and the swing arm support module 121 is detachably mounted on the base plate module 13. By setting the base plate module 13 to support and install the arrangement support module 11 and the swing arm support module 121, the structural strength of the base portion 10 can be improved, ensuring that the base portion 10 can stably support the audio support portion 20. At the same time, the detachable connection between the arrangement support module 11 and / or the swing arm support module 121 and the base plate module 13 allows the vibration isolation device in this embodiment to quickly replace the arrangement support module 11 and / or the swing arm support module 121 according to different working conditions. Furthermore, the base plate module 13 can also attenuate the vibration energy transmitted from the base to the base portion 10 to a certain extent, improving the vibration isolation effect of the vibration isolation device.
[0052] See Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, in a specific embodiment, the base plate module 13 includes a base plate body 131 and a support foot assembly 132. The support foot assembly 132 is detachably installed on the base plate body 131, and the base plate body 131 is placed on the base via the support foot assembly 132. The base plate body 131 forms the bottom wall structure of the base. By detachably installing the support foot assembly 132 on the base plate body 131 and setting the base plate body 131 to be placed on the base via the support foot assembly 132, the base plate module 13 in this embodiment can adapt to the flatness or inclination of the base surface by adjusting the installation position of the support foot assembly 132 or replacing it with a support foot assembly 132 of different specifications. Furthermore, setting the support foot assembly 132 to be detachably installed on the base plate body 131 makes it convenient for users to replace worn parts of the support foot assembly 132 or select support foot assemblies 132 of different materials according to different vibration isolation requirements, thereby improving the vibration energy attenuation effect of the base plate module 13 to a certain extent.
[0053] In some embodiments, the support foot assembly 132 includes an elastic support pad and a third connecting screw. The base plate body 131 has multiple spaced-apart third connecting threaded holes. The elastic support pad has a connecting through hole. The third connecting screw passes through the connecting through hole and engages with one of the multiple third connecting threaded holes to detachably install the elastic support pad on the side of the base plate body 131 opposite to the audio support portion 20. The elastic support pad has a support surface that contacts the substrate, and the third connecting screw is located above the support surface. By cooperating with different third connecting threaded holes, the installation position of the elastic support pad on the base plate body 131 can be changed, ensuring that the support foot assembly 132 has good load-bearing stability. Furthermore, the elastic cushioning effect of the elastic support pad can isolate the vibration transmission of the substrate to a certain extent, further improving the vibration isolation effect of the vibration isolation device.
[0054] In some embodiments, the elastic support pad in this embodiment is made of silicone. Of course, in other embodiments, the elastic support pad in this embodiment can also be made of other elastic materials such as polyurethane elastomer or nitrile rubber.
[0055] In some embodiments, the support body 12111 in this embodiment is detachably mounted to the base plate body 131 via threaded fasteners. The detachable connection between the support body 12111 and the base plate body 131 via threaded fasteners ensures a stable and reliable connection between them. Furthermore, it facilitates independent disassembly and maintenance of the support body 12111, effectively reducing the maintenance cost of the vibration isolation device. Of course, in other embodiments, the support body 12111 and the base plate body 131 in this embodiment can also be connected via other detachable methods such as magnetic connection or snap-fit connection.
[0056] See Figure 1 and Figures 3 to 8 As shown, in one specific embodiment, the base portion 10 further includes a sidewall module 14. The sidewall module 14 is detachably installed on the base plate module 13 and located between two adjacent swing arm support modules 121. Both sides of the sidewall module 14 are respectively positioned and engaged with the two adjacent swing arm support modules 121 to form a base sidewall structure between the two adjacent swing arm support modules 121. By setting the sidewall module 14 between the two adjacent swing arm support modules 121, and simultaneously positioning and engaging both sides of the sidewall module 14 with the two adjacent swing arm support modules 121, the base portion 10 can form a base sidewall structure between the two adjacent swing arm support modules 121 through the sidewall module 14, enhancing the overall rigidity of the base portion 10. Furthermore, by making the sidewall module 14 detachably installed on the base plate module 13, the base portion 10 can flexibly adjust the installation position of the sidewall module 14 or replace it with a sidewall module 14 with different damping characteristics according to actual vibration isolation requirements. While ensuring the structural stability of the base portion 10, this effectively reduces the maintenance and upgrading difficulty of the vibration isolation device. It should be noted that the side wall module 14 in this embodiment has various size specifications. When the interval between two adjacent swing arm support modules 121 changes due to the change of the size specifications of the arrangement support modules 11, by selecting the side wall module 14 of the corresponding size specifications, the base side wall structure can be quickly rebuilt between the two adjacent swing arm support modules 121 after the interval distance changes. This effectively reduces the update cost of the vibration isolation device and improves the production compatibility of the vibration isolation device. The distance between the two sides of the side wall module 14 is the size specification of the side wall module 14.
[0057] In some embodiments, the sidewall module 14 and the base plate body 131 in this embodiment are made of aluminum alloy. Of course, in other embodiments, the sidewall module 14 and the base plate body 131 in this embodiment may also be made of other metal materials.
[0058] In some embodiments, the base portion 10 of this embodiment includes a plurality of sidewall modules 14, which are correspondingly disposed between each pair of adjacent swing arm support modules 121. The plurality of sidewall modules 14 and the plurality of swing arm support modules 121 together form a closed base sidewall structure. By forming a closed base sidewall structure together with the plurality of sidewall modules 14 and the plurality of swing arm support modules 121, the overall rigidity of the base portion 10 can be further enhanced.
[0059] In some embodiments, the sidewall module 14 and the base plate module 13 are detachably connected via threaded fasteners. This detachable connection ensures a stable and reliable connection between the sidewall module 14 and the base plate module 13, and also facilitates independent disassembly and maintenance of the sidewall module 14, effectively reducing the maintenance cost of the vibration isolation device. Of course, in other embodiments, the sidewall module 14 and the base plate module 13 can also be connected via magnetic connections, snap-fit connections, or other detachable methods.
[0060] See Figure 2 , Figure 7 and Figure 8 As shown, in a specific embodiment, the audio support unit 20 includes an upper cover module 21. The upper cover module 21 includes an upper cover body 211 and an audio support plate 212. The upper cover body 211 is mounted on multiple swing arm support modules 121, and the audio support plate 212 is mounted on the upper cover body 211. The upper cover body 211 supports the audio device through the audio support plate 212. By mounting the upper cover body 211 on multiple swing arm support modules 121 and setting the audio support plate 212 to be mounted on the upper cover body 211, the upper cover body 211 can support the audio device through the audio support plate 212. Furthermore, the separate arrangement of the upper cover body 211 and the audio support plate 212 allows the upper cover module 21 to adapt to different types of audio devices by replacing the audio support plate 212 individually, reducing the replacement cost of the vibration isolation device.
[0061] In some embodiments, the upper cover body 211 in this embodiment is made of aluminum alloy. Of course, in other embodiments, the upper cover body 211 in this embodiment may also be made of other metal materials.
[0062] In some embodiments, the audio support plate 212 in this embodiment is made of wood. Of course, in other embodiments, the audio support plate 212 in this embodiment may also be made of other metal or non-metal materials.
[0063] In some embodiments, a mounting boss is provided on the side of the upper cover body 211 near the base portion 10, and a second positioning groove is provided on the mounting boss. A second positioning protrusion is provided on the side of the support component 1212 near the upper cover body 211. The support component 1212 is quickly positioned on the mounting boss through the sliding engagement of the second positioning protrusion and the second positioning groove. Through the sliding engagement structure of the second positioning groove and the second positioning protrusion, the support component 1212 can be quickly and accurately positioned on the mounting boss, improving the assembly efficiency of the support component 1212 while ensuring that the vibration isolation device has good assembly accuracy and structural stability.
[0064] In some embodiments, the support component 1212 in this embodiment is detachably mounted to the upper cover body 211 via threaded fasteners. The detachable connection between the support component 1212 and the upper cover body 211 via threaded fasteners ensures a stable and reliable connection between them. Furthermore, it facilitates independent disassembly and maintenance of the support component 1212, effectively reducing the maintenance cost of the vibration isolation device. Of course, in other embodiments, the support component 1212 and the upper cover body 211 in this embodiment can also be connected via other detachable methods such as magnetic connection or snap-fit connection.
[0065] In some embodiments, the audio support portion 20 further includes an elastic buffer 22. In this embodiment, the elastic buffer 22 is sleeved on the outer wall of the mounting boss. When the audio support portion 20 translates relative to the base portion 10 along a direction perpendicular to the swing axis of the swing arm support module 121, the mounting boss can contact the base portion 10 through the elastic buffer 22 to avoid rigid collisions between the mounting boss and the base portion 10. By providing the elastic buffer 22 on the outer side of the mounting boss, the audio support portion 20 can absorb impact energy through the elastic buffer 22, avoiding rigid collisions between the mounting boss and the base portion 10, reducing vibration transmission noise, and extending the service life of the vibration isolation device.
[0066] In some embodiments, the elastic buffer 22 in this embodiment is made of silicone. Of course, in other embodiments, the elastic buffer 22 in this embodiment can also be made of other elastic materials such as polyurethane elastomer or nitrile rubber.
[0067] According to another aspect of this application, an audio device is provided, the audio device including an audio unit, a vibration isolation device and a base, wherein the vibration isolation device is installed between the audio unit and the base, and the vibration isolation device is the aforementioned vibration isolation device.
[0068] In summary, implementing the vibration isolation device and audio equipment provided in this embodiment has at least the following beneficial technical effects: The vibration isolation device provided in this embodiment, by installing multiple swing arm support modules 121 spaced apart on the arrangement support module 11, and simultaneously installing the audio support part 20 on the multiple swing arm support modules 121, allows the vibration energy transmitted from the audio device to the audio support part 20 to be converted into translational motion of the audio support part 20 perpendicular to the swing axis of the swing arm support module 121. Thus, the vibration isolation device can dissipate the vibration energy transmitted from the audio device to the audio support part 20 through the movement of the swing arm support module 121, thereby achieving vibration reduction of the audio support part 20. This decouples the vibration transmitted from the audio device to the substrate. Meanwhile, since the swing arm support assembly 12 is detachably installed on the arrangement support module 11, and the arrangement support module 11 has various sizes, the vibration isolation device provided in this embodiment can increase or decrease the maximum arrangement spacing of the swing arm support module 121 in the first direction and / or the second direction by replacing the arrangement support module 11 of different sizes, thereby forming vibration isolation devices of different sizes to adapt to audio devices of different sizes. Since vibration isolation devices of different sizes can share the swing arm support module 121, the production cost of vibration isolation devices of different sizes can be effectively reduced.
[0069] 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.
