Description

Technical Field

[0001] This invention belongs to the field of microphone auxiliary equipment, specifically relating to a support structure for a sound acquisition device. Background Technology

[0002] The description in this section provides only background information relevant to the disclosure of this application and does not constitute prior art.

[0003] A microphone (also known as a transducer or microphone, formally called a "transmitter") is a transducer that converts sound into electrical signals. It works by placing an audio pickup device at the end of the microphone body and connecting it to the microphone. Furthermore, this audio pickup device includes a pickup unit and an amplification circuit. The microphone body itself houses an audio processing unit. See the appendix for a detailed design. Figure 2 , 3 As shown, it can receive sound signals, convert them into audio signals, and then output them after processing by an audio processing unit.

[0004] Microphones are generally categorized into performance microphones, recording microphones, and conference microphones. In these scenarios, microphones are typically equipped with stands for support. These stands include a first support rod 20 with a clamp and a first counterweight base 21 mounted at the bottom of the first support rod 20. (See appendix.) Figure 1 As shown, its purpose is to facilitate the use of the microphone by the user. The user can choose to hold the microphone or place it on the stand. When the microphone stand is used, the microphone is positioned and fixed in the desired position, so that performers, musicians or other users in different application scenarios can use both hands freely and keep the microphone in a consistent and known position.

[0005] In some situations, users may need to adjust the microphone's position. In such cases, the microphone mounting bracket may feature an adjustable clamp, which typically secures the microphone by engaging a nut. When adjusting the microphone, the nut must be manually adjusted, resulting in inconvenience. Existing technologies offer several solutions to this problem, such as the holder for a cylindrical body and microphone bracket disclosed in JP5715912B2. This patent provides a solution that allows for easy installation and removal of the microphone with a single touch and provides reliable retention. However, while convenient microphone removal is important, it doesn't fully address user comfort. Therefore, there is still room for improvement and refinement in this area.

[0006] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application. Summary of the Invention

[0007] The purpose of this invention is to provide a support structure for a sound acquisition device, which can improve the ease of assembling and disassembling the microphone, avoid noise during microphone handling and use, and ensure that the microphone's range of motion can be freely adjusted, thereby improving user comfort.

[0008] The technical solution adopted by the present invention to achieve the above objectives is: a support structure for a sound acquisition device, comprising:

[0009] The limiting component has a detachable microphone mounted on it.

[0010] The second support rod is connected to the limiting component.

[0011] The limiting component includes a limiting base, which abuts against the outer wall of the microphone. A first limiting ring plate arranged in an arc shape is provided on the outer side of the limiting base, and a first limiting connecting pin is provided on the side of the limiting base. The first limiting ring plate is connected to the first limiting ring plate body and the first limiting connecting pin by a metal wire to form a gap distance with the limiting base.

[0012] The limiting base includes two opposing arc-shaped limiting arc plates, which are connected by a second limiting connecting pin, and a swingable tension adjustment plate is connected to the second limiting connecting pin at the end of the limiting arc plate.

[0013] The support structure for sound acquisition devices using the present invention has significant advantages. The invention employs a limiting base that abuts against the microphone to ensure effective contact, facilitating stable placement of the microphone on the support structure. Furthermore, the invention utilizes a swingable tension adjustment plate to further limit contact with the microphone, and this tension adjustment plate can swing relative to the limiting arc plate. This allows users to directly place the microphone onto the limiting base, with the tension adjustment plate automatically adjusting the microphone tension according to its diameter. Removing the microphone is as simple as lifting it; the lifting force is greater than the limiting force of the tension adjustment plate. This improves the ease of microphone assembly and disassembly, and ensures the support structure is suitable for microphones of different sizes. More importantly, the limiting component of the present invention allows for direct picking up and placing of the microphone on the support structure, effectively reducing and avoiding the possibility of collisions between the microphone and the support structure or the limiting component. This effectively avoids noise and collision noise generated during microphone picking or orientation, especially in performance and recording scenarios.

[0014] In addition, the vibration energy generated by the microphone placed on this support structure during use can be dissipated by the metal wire wrapped between a limiting ring plate and a limiting base. This effectively avoids vibration when the microphone is placed. The design of the metal wire also makes it easier for the user to quickly position the limiting component and adjust the tilt angle of the inner microphone by the deformation of the metal wire, ensuring the free adjustment of the microphone's range of motion and improving user comfort.

[0015] According to one embodiment of the present invention, the side of the tension adjustment plate can abut against the adjacent surface of the limiting arc plate. When the microphone is placed on the limiting arc plate of the limiting base, the microphone presses down and abuts against the surface of the limiting arc plate. At the same time, the downward pressure causes the lower part of the tension adjustment plate to swing downward, thereby realizing that the microphone is placed on the limiting arc plate in one go. When the lower part of the tension adjustment plate swings downward, its upper part swings along with it, thereby realizing the limiting abutment against the part of the limiting arc plate that does not contact the microphone. The design that the side of the tension adjustment plate can abut against the adjacent surface of the limiting arc plate can eliminate or avoid the influence of the arbitrary rotation of the tension adjustment plate on the placement and removal of the microphone.

[0016] According to one embodiment of the present invention, a limiting support rod is also connected between the two limiting arc plates, and the first limiting connecting pins are respectively arranged on the outer side of the limiting arc plates. Since the second limiting connecting pin is provided between the two limiting arc plates, a gap can be formed between the two limiting arc plates. However, in the unsupported area, the spacing between the limiting arc plates may change, which is not conducive to maintaining the contact between the entire limiting base shape and the microphone. By designing the limiting support rod, the spacing between the two limiting arc plates can be ensured to be controllable.

[0017] According to one embodiment of the present invention, the tension adjusting plate includes an arc-shaped first tension plate and a second tension plate hinged to the first tension plate.

[0018] The first tension plate has a second limiting connecting ring on one side. The second tension plate is adjacent to the first tension plate and has a first limiting connecting ring that corresponds to and cooperates with the second limiting connecting ring. The first limiting connecting ring and the second limiting connecting ring are connected by a limiting plug. The limiting plug has a through hole in the middle through which the second limiting connecting pin can pass.

[0019] As the microphone presses down to abut against the surface of the limiting arc plate, the downward pressure causes the first tensioning plate at the bottom of the tension adjustment plate to swing downward, thus allowing the microphone to be placed onto the limiting arc plate in one go. When the first tensioning plate at the bottom of the tension adjustment plate swings downward, the second tensioning plate at the top swings along with it, thereby limiting and abutting the part of the limiting arc plate that does not contact the microphone. This improves the ease of microphone assembly and disassembly, ensures that this support structure is suitable for microphones of different specifications, and effectively reduces and avoids the possibility of collision between the microphone and the support structure or the limiting components.

[0020] According to one embodiment of the present invention, the first tensioning plate and the second tensioning plate are provided with corresponding limiting holes on their opposite surfaces. A first rubber post is inserted into the limiting hole. A through groove is provided on the first rubber post through which a second limiting connecting pin can pass and can be displaced. A limiting tensioning spring is also provided in the limiting hole, and the limiting tensioning spring abuts against the end of the first rubber post. The first and second tension plates, as described above, ensure that the limiting arc plate does not come into contact with the microphone portion for limiting and abutment. The first and second tension plates are connected by a tension spring and a first rubber post, allowing them to bend and recover their elastic deformation. This improves the ease of microphone assembly and disassembly. It should also be noted that during microphone use, the microphone surface may come into contact with residual sweat from hands. The tension spring and first rubber post expand the contact area with the microphone and provide a tension clamping effect. Furthermore, the tension clamping presses downwards from the top of the microphone, maintaining continuous contact between the microphone and the limiting arc plate, thus solving the problem of the microphone slipping or shifting during placement due to a wet surface.

[0021] According to one embodiment of the present invention, the second support rod is connected to the limiting assembly via an adjusting assembly. The adjusting assembly includes a third base sleeve, to which the second base sleeve is detachably connected. A limiting assembly hole is provided on one side of the third base sleeve, and a threaded hole communicating with the limiting assembly hole is provided on the other side. The third base sleeve is connected to the second base sleeve via a second fastener and the threaded hole. The second base sleeve has a cylindrical sleeve structure with threads on its outer side. A first base sleeve is threadedly connected to the outer side of the second base sleeve. Both ends of the first base sleeve are through-type. A spherical adjusting ball is provided inside the first base sleeve. The adjusting ball is connected to a rod extending to the outside of the first base sleeve, and the rod is connected to a first limiting ring plate. The bottom of the first limiting ring plate has a connecting plate that connects to the rod, and the end of the rod has a slot for connecting to the connecting plate and a fastener. The end diameter of the spherical adjusting ball in the first base sleeve is reduced, and the end diameter is smaller than the diameter of the adjusting ball. The adjustment assembly can be disassembled and installed by means of a second base sleeve, a third base sleeve and a limiting assembly hole, so that the parts are easy to replace. By setting a spherical adjustment ball inside the first base sleeve, it can drive the existing limiting ring plate to swing and rotate, thereby realizing the free adjustment range of the microphone in the placement state, which is convenient for users.

[0022] According to one embodiment of the present invention, the end of the second base sleeve is located inside the first base sleeve and the end is provided with a limiting plate. A rubber base is provided between the limiting plate and the upper adjusting ball. The surface of the limiting plate is provided with a protrusion. A third fastener is connected to one side of the first base sleeve. The end of the third fastener is located inside the first base sleeve and corresponds to the horizontal height of the protrusion. At least two steel balls are placed between the end of the third fastener and the protrusion.

[0023] This invention uses a limiting plate to control the range of motion of the steel ball for easy adjustment. A third fastener is used to compress the steel ball, thus controlling its position under pressure. The continuous rotation of the third fastener compresses the upper rubber base, which in turn deforms and compresses the upper adjusting ball. The ball's swing and rotation are restricted by the bottom rubber base, and friction exists between the ball and the base during rotation. This prevents the ball from swinging arbitrarily or changing position due to the microphone's weight. Furthermore, if the upward displacement of the bottom steel ball is too large, the adjusting ball can be locked, preventing it from swinging or rotating. This controls the tightness of the adjusting ball's rotation, facilitating user adjustment of the microphone's range of motion. Additionally, compared to vibrations caused by the microphone's free assembly and disassembly on the limiting component, vibrations transmitted to the rubber base are blocked, preventing downward transmission to the lower second support rod.

[0024] According to one embodiment of the present invention, a first fastener is threadedly connected to the side of the first base sleeve, with a horizontal height higher than the height of the raised top surface on the rubber base. The end of the first fastener is located inside the first base sleeve and abuts against the rubber base. By designing the first fastener to abut against one side of the rubber base, it is ensured that the rubber base always maintains contact with the adjusting ball, thereby maintaining the rotation tightness of the adjusting ball and avoiding arbitrary swinging and rotation of the adjusting ball due to the lack of friction restriction from the rubber base.

[0025] According to one embodiment of the present invention, a second counterweight base is connected to the bottom of the second support rod. The second counterweight base is provided with hinge mounting slots around its perimeter. A hinge plate is provided in the hinge mounting slots and a limiting support rod is hinged thereto. The arrangement of the second counterweight base and the limiting support rod is used to ensure that the second support rod is placed stably on the ground and can adapt to ground with different flatness through the limiting support rod.

[0026] According to one embodiment of the present invention, a first base plate is provided at the bottom of the second counterweight chassis, and a hinged connecting seat is arranged around the bottom of the second support rod. The limiting support rod can be connected to the hinged connecting seat. By designing the connection scheme between the hinged connecting seat and the limiting support rod, direct support for the second support rod is achieved, providing multiple support schemes for the second support rod and ensuring the stability of the second support rod during use.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows: The support structure for the sound acquisition device of the present invention has obvious advantages. The present invention uses a limiting base to abut against the microphone to ensure effective contact with the microphone, which is beneficial to the stability of the microphone placed on the support structure. On this basis, the present invention uses a swingable tension adjustment plate to further limit the contact with the microphone, and the tension adjustment plate can swing relative to the limiting arc plate. In this way, the user can directly place the microphone on the limiting base and the tension adjustment plate will automatically adjust the tension of the microphone according to the microphone diameter. When removing the microphone, it can be lifted directly. The lifting force is greater than the limiting force of the tension adjustment plate. This improves the convenience of microphone assembly and disassembly and ensures that the support structure is suitable for microphones of different specifications.

[0028] As described above, the present invention provides a support structure for a sound acquisition device that improves the ease of assembling and disassembling the microphone, avoids noise during microphone handling and use, and ensures that the microphone's range of motion can be freely adjusted, thereby enhancing user comfort.

[0051] The technical solution of the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings: Example

[0052] A support structure for a sound acquisition device, as shown in the attached figure. Figure 4 As shown, the support structure has a second support rod 60, the diameter of which is preferably φ2.5cm-φ20cm. The second support rod 60 can be a telescopic rod that can be extended or retracted. The telescopic rod is suitable for children and adults. The total telescopic length of the telescopic rod is between 0.5m and 2.5m. Of course, under appropriate conditions, the total telescopic length can be extended or reduced.

[0053] A limiting component 30 is installed at the end of the second strut 60 of this support structure. In this embodiment, the limiting component 30 is used to place the microphone 10.

[0054] Further description is needed: as attached Figure 8 and attached Figure 9As shown, the limiting component 30 includes a limiting base 33, which abuts against the outer wall of the microphone 10. A first limiting ring plate 31 arranged in an arc shape is provided on the outer side of the limiting base 33. A first limiting connecting pin 34 is provided on the side of the limiting base 33. The first limiting ring plate 31 is connected to the body of the first limiting ring plate 31 and the first limiting connecting pin 34 by a metal wire 35 to form an interval distance with the limiting base 33.

[0055] The limiting base 33 includes two opposing arc-shaped limiting arc plates 331, which are connected by a second limiting connecting pin 333, and a swingable tension adjustment plate 36 is connected to the second limiting connecting pin 333 at the end of the limiting arc plate 331.

[0056] In the use of microphone 10, especially in performance and recording scenarios, the existing technology generally adopts a simple support frame to place microphone 10. Some support frames have adjustable height to take into account the height of the user. Microphone 10 is generally placed by clamping with a clip-like structure or by using nuts to hold microphone 10 together.

[0057] Compared to other methods, the support structure for the sound acquisition device of this invention has significant advantages. This invention uses a limiting base 33 to abut against the microphone 10, ensuring effective contact and facilitating the stability of the microphone placed on the support structure. Furthermore, this invention employs a swingable tension adjustment plate 36 to further limit contact with the microphone 10. This tension adjustment plate 36 can swing relative to the limiting arc plate 331, allowing the user to directly place the microphone 10 onto the limiting base 33 and have the tension adjustment plate 36 automatically adjust the tension of the microphone 10 according to its diameter. When removing the microphone 10, it can be lifted directly. The lifting force is greater than the limiting force of the tension adjustment plate 36. This improves the ease of assembling and disassembling the microphone and ensures that the support structure is suitable for microphones of different specifications. More importantly, the limiting component of this invention enables the microphone 10 to be picked up and placed directly on the support structure, effectively reducing and avoiding the possibility of collision between the microphone 10 and the support structure or the limiting component 30. This effectively avoids noise and collision noise generated during the picking up or directional movement of the microphone 10, especially noise in performance and recording scenarios.

[0058] In addition, the vibration energy generated by the microphone 10 placed on this support structure during use can be dissipated by the metal wire 35 wrapped between a limiting ring plate 31 and a limiting base 33. This can effectively prevent vibration when the microphone is placed. Furthermore, the design of the metal wire 35 also facilitates the user's hand to quickly position the limiting component 30 and adjust the tilt angle of the inner microphone 10 by the deformation of the metal wire 35, ensuring the free adjustment of the microphone's range of motion and improving user comfort.

[0059] It should be noted that an audio acquisition device is provided at the end of the microphone body and connected to the microphone. This audio acquisition device has a pickup unit and an amplification circuit, which are existing technologies and will not be described in detail in this invention.

[0060] As attached Figure 9 As shown, the side of the tension adjustment plate 36 can abut against the adjacent surface of the limiting arc plate 331. When the microphone 10 is placed on the limiting arc plate 331 of the limiting base 33, the microphone 10 presses down and abuts against the surface of the limiting arc plate 331. At the same time, the downward pressure causes the lower part of the tension adjustment plate 36 to swing downward, thereby realizing that the microphone 10 is placed on the limiting arc plate 331 in one go. When the lower part of the tension adjustment plate 36 swings downward, its upper part swings along with it, thereby achieving limiting abutment against the part of the limiting arc plate 331 that does not contact the microphone 10. The design that the side of the tension adjustment plate 36 can abut against the adjacent surface of the limiting arc plate 331 can eliminate or avoid the random rotation of the tension adjustment plate 36 affecting the placement and removal of the microphone 10.

[0061] As attached Figure 10 As shown, in this embodiment, a limiting support rod 332 is also connected between the two limiting arc plates 331, and the first limiting connecting pin 34 is respectively arranged on the outer side of the limiting arc plate 331. Since the second limiting connecting pin 333 is provided between the two limiting arc plates 331, a gap can be formed between the two limiting arc plates 331. However, in the unsupported area, the spacing between the limiting arc plates 331 may change, which is not conducive to maintaining the contact between the entire limiting base 33 and the microphone 10. By designing the limiting support rod 332, the spacing between the two limiting arc plates 331 can be controlled.

[0062] The tension adjusting plate 36 includes an arc-shaped first tension plate 361 and a second tension plate 365 hinged to the first tension plate 361.

[0063] The first tension plate 361 has a second limiting connecting ring 367 on one side. The second tension plate 365 is adjacent to the first tension plate 361 and has a first limiting connecting ring 364 that corresponds to and cooperates with the second limiting connecting ring 367. The first limiting connecting ring 364 and the second limiting connecting ring 367 are connected by a limiting insert 362. The limiting insert 362 has a through hole in the middle through which the second limiting connecting pin 333 can pass.

[0064] When the microphone 10 is pressed down to abut against the surface of the limiting arc plate 331, the downward pressure causes the first tension plate 361 at the bottom of the tension adjustment plate 36 to swing downward, thereby enabling the microphone 10 to be placed on the limiting arc plate 331 in one go. When the first tension plate 361 at the bottom of the tension adjustment plate 36 swings downward, the second tension plate 365 at the top swings along with it, thereby limiting and abutting the part of the limiting arc plate 331 that does not contact the microphone 10. This improves the ease of installation and removal of the microphone 10, ensures that the support structure is suitable for microphones of different specifications, and effectively reduces and avoids the possibility of collision between the microphone 10 and the support structure or the limiting component 30.

[0065] As attached Figure 10 and attached Figure 11 As shown, the first tensioning plate 361 and the second tensioning plate 365 are respectively provided with corresponding limiting holes 368 on their opposite surfaces. A first rubber post 366 is inserted into the limiting hole 368. A through groove is provided on the first rubber post 366 so that a second limiting connecting pin 333 can pass through and can be displaced. A limiting tension spring 363 is also provided in the limiting hole 368, and the limiting tension spring 363 abuts against the end of the first rubber post 366. The first tension plate 361 and the second tension plate 365, as described above, ensure that the limiting arc plate 331 does not come into contact with the microphone 10 for limiting and abutting. The first tension plate 361 and the second tension plate 365 are connected by a tension spring 363 and a first rubber post 366, which allows the first tension plate 361 and the second tension plate 365 to bend and recover their elastic deformation. This improves the ease of assembling and disassembling the microphone 10. It should also be noted that during the use of the microphone 10, the surface of the microphone 10 may come into contact with residual sweat from the hands. In this case, the tension spring 363 and the first rubber post 366 expand the contact area with the microphone 10 and provide a tension clamping effect. The tension clamping is applied downward from the top of the microphone 10 to keep the microphone 10 in continuous contact with the limiting arc plate 331, thereby solving the problem that the microphone 10 may slip or shift during placement due to a wet surface. Example

[0066] This embodiment further provides the following solution based on embodiment 1: as shown in the appendix. Figure 12As shown, the second support rod 60 is connected to the limiting component 30 via the adjusting component 40. The adjusting component 40 includes a third base sleeve 46, on one side of which a second base sleeve 45 is detachably connected. A limiting assembly hole 47 is provided on one side of the third base sleeve 46, and a threaded hole communicating with the limiting assembly hole 47 is provided on the other side. The third base sleeve 46 is connected to the second base sleeve 45 via a second fastener 48 and the threaded hole. The second base sleeve 45 has a cylindrical structure and is threaded on its outer side. A first base sleeve 42 is threadedly connected to the outer side of the second base sleeve 45. The first base sleeve 42 has through-holes at both ends and contains a spherical adjusting ball 41. The adjusting ball 41 is connected to a rod extending outside the first base sleeve 42, and the rod is connected to a first limiting ring plate 31. The bottom of the first limiting ring plate 31 has a connecting plate 32 that connects to the rod, and the end of the rod has a slot for connecting to the connecting plate 32 and a fastener. The first base sleeve 42 has a spherical adjusting ball 41 with a reduced end diameter, the end diameter being smaller than the diameter of the adjusting ball 41. The adjusting assembly 40 can be disassembled and reassembled by using a second base sleeve 45, a third base sleeve 46, and a limiting mounting hole 47, making the parts easy to replace. The spherical adjusting ball 41 inside the first base sleeve 42 allows it to drive the existing limiting ring plate 31 to swing and rotate, thereby enabling the microphone 10 to freely adjust its range of motion in its placed state, facilitating user operation.

[0067] As attached Figure 12 As shown, the second base sleeve 45 is located inside the first base sleeve 42 and has a limiting plate 44 at its end. A rubber base 411 is provided between the limiting plate 44 and the upper adjusting ball 41. The surface of the limiting plate 44 has a protrusion. A third fastener 410 is connected to one side of the first base sleeve 42. The end of the third fastener 410 is located inside the first base sleeve 42 and corresponds to the horizontal height of the protrusion. At least two steel balls are placed between the end of the third fastener 410 and the protrusion. Preferably, the bottom of the adjusting ball 41 has a flat surface, and the rubber base 411 has an annular structure with one side of the annular structure sealed. The sealed surface is adjacent to the limiting plate 44.

[0068] This invention uses a limiting plate 44 to control the movable range of the steel ball 49 for easy adjustment, and a third fastener 410 to compress the steel ball 49, thereby controlling its position after being compressed. The continuous rotation of the third fastener 410 causes the steel ball 49 to compress the upper rubber base 411, which in turn deforms and compresses the upper adjusting ball 41. The swing and rotation of the adjusting ball 41 are restricted by the bottom rubber base 411, and friction exists between the adjusting ball 41 and the rubber base 411 during rotation. This prevents the adjusting ball 41 from swinging arbitrarily or changing its position due to the gravity of the microphone 10. In this way, if the deformation of the bottom steel ball 49 is too large when it moves upward, the adjusting ball 41 can be locked directly, preventing it from swinging or rotating. This controls the tightness of the rotation of the adjusting ball 41, making it easier for the user to adjust the free range of motion of the microphone 10. At the same time, compared with the vibration caused by the free disassembly and assembly of the microphone 10 on the limiting component 30, the vibration transmitted to the rubber base 411 can be blocked, preventing the vibration from being transmitted downward to the second support rod 60 below.

[0069] The first base sleeve 42 is threadedly connected to a first fastener 43 with a horizontal height higher than the raised top surface of the rubber base 411. The end of the first fastener 43 is located inside the first base sleeve 42 and abuts against the rubber base 411. The first fastener 43 is designed to abut against one side of the rubber base 411, thus ensuring that the rubber base 411 always maintains contact with the adjusting ball 41, thereby maintaining the rotation tightness of the adjusting ball 41 and preventing the adjusting ball 41 from swinging and rotating arbitrarily due to the lack of friction restriction from the rubber base 411.

[0070] As attached Figure 13 As shown, the bottom of the second support rod 60 is connected to the second counterweight base 70. The second counterweight base 70 has hinge mounting slots 75 around its perimeter. The hinge mounting slots 75 are equipped with hinge plates and hinged to limit support rods 72. The arrangement of the second counterweight base 70 and the limit support rods 72 is used to ensure that the second support rod 60 is placed stably on the ground, and the limit support rods 72 can adapt to ground with different flatness.

[0071] The second counterweight chassis 70 has a first base plate 71 at its bottom, and the second support rod 60 has a hinged connecting seat 73 arranged around its bottom. The limiting support rod 72 can be connected to the hinged connecting seat 73. By designing the connection scheme between the hinged connecting seat 73 and the limiting support rod 72, the second support rod 60 can be directly supported, providing a variety of support schemes for the second support rod 60 and ensuring the stability of the second support rod 60 during use. Example

[0072] See appendix Figure 4 As shown, the second support rod 60 is provided with a shock-absorbing component 50. The shock-absorbing component 50 includes a first base 56 with a column sleeve structure. The first base 56 is surrounded by a first opening 57. The inner wall of the first base 56 is surrounded by a limiting insert 58. The limiting insert 58 is arranged parallel to the axis of the column sleeve of the first base 56. The bottom end of the limiting insert 58 is fixed to the inner wall of the first base 56, and the first base 56 is arranged adjacent to the first opening 57.

[0073] A first connecting post 53 is inserted into the first base 56. The first connecting post 53 is coaxial with the axis of the first base 56. Two parallel second connecting posts 55 are connected to the bottom surface of the first connecting post 53. The second connecting posts 55 are parallel to the axis of the first connecting post 53. A circular flexible ring 54 is sleeved on the second connecting post 55. The second connecting post 55 is provided with a mounting groove for limiting the displacement of the flexible ring 54 on the second connecting post 55. The flexible ring 54 can be sleeved with the limiting insert 58.

[0074] One end of the first base 56 is threadedly connected to a first connecting ring 51. A second mounting hole 52 is provided in the middle of the first connecting ring 51. The first connecting post 53 can pass through the second mounting hole 52 and connect to the upper second support rod 60 or the limiting mounting hole 47. The other end of the first base 56 has a reduced diameter and is provided with a second mounting hole 510 that can connect to the second support rod 60. Inside the first base 56 at the end of the second mounting hole 510, there is also a shock-absorbing ring 59 that can be inserted into the end of the second support rod 60. The shock-absorbing ring 59 is preferably made of rubber.

[0075] As above Figure 4 As shown, the present invention provides a shock-absorbing component 50, which is mounted on a second support rod 60. Optionally, the shock-absorbing component 50 can be mounted on the upper and lower ends of the second support rod 60 respectively, which facilitates the installation and removal of the second support rod 60 and provides different operating heights.

[0076] The shock-absorbing component 50 provided in this invention has a flexible ring 54 mounted on the second connecting post 55, and a limiting insert 58 is arranged around the inside of the first base sleeve 56. This allows the flexible ring 54 to be fitted onto the limiting insert 58. When external vibrations are transmitted to the first base sleeve 56 or the first connecting post 53, the vibration energy can be consumed during the deformation of the flexible ring 54 relative to the limiting insert 58. Especially during performances or recordings, when a person or object collides with the second support rod 60, the second support rod 60 is prone to impact vibration. In this case, the vibration energy is consumed by the flexible ring 54 during the deformation of the flexible ring 54 relative to the limiting insert 58, solving the problem that the vibration of the second support rod 60 being impacted is transmitted to the upper microphone 10 and converted into an electrical signal, forming noise. At the same time, the first connecting post 53 of the shock-absorbing component 50 is limited by the first connecting ring 51 to ensure its vertical displacement. This ensures the vertical stability of the components connected to the upper part of the first connecting post 53 under impact conditions, without shaking, thus effectively ensuring the vertical stability of the microphone 10 under the impact condition of the second support rod 60. Example

[0077] See appendix Figure 14 As shown, the second support rod 60 is connected to a windproof cover 80 via a connecting plate. The windproof cover 80 is vertically mounted on one side of the microphone 10. The windproof cover 80 is designed to prevent wind noise from affecting the microphone 10's performance during use.

[0078] The above embodiments are for illustrative purposes only and are not intended to limit the invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, all equivalent technical solutions also fall within the scope of this invention, and the patent protection scope of this invention should be defined by the claims.
