Description

Technical Field

[0001] The invention belongs to the field of microphone auxiliary equipment, and in particular relates to a supporting structure for a sound collecting device. Background Art

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

[0003] Microphone (also known as micro-phone or microphone, the official Chinese name is microphone), translated from English Microphone, is a transducer that converts sound into electrical signals. It is achieved by setting an audio collection device at the end of the microphone body and connecting it to the microphone. Furthermore, the audio collection device has a pickup unit and an amplification circuit, and an audio processing unit is arranged inside the microphone body. For specific solutions, please refer to the attached Figure 2 , 3 As shown, it is possible to convert the received sound signal into an audio signal and then output it to the audio processing unit for processing and output.

[0004] Microphones are generally used for performances, recordings, and conferences. In these usage scenarios, microphones are usually equipped with a bracket for supporting the microphone. The bracket includes a first support rod 20 with a clamp and a first counterweight chassis 21 at the bottom of the first support rod 20. Figure 1 As shown, its purpose is to facilitate the user to use the microphone. The user can choose to hold the microphone in hand or place it on a stand. When the microphone stand is used, the microphone is located and fixed in the desired position, so that performers, musicians or other users in different application scenarios can use both hands freely and the microphone is located in a consistent and known position.

[0005] In some cases, the user may need to adjust the position of the microphone. In this case, the bracket on which the microphone is mounted may have the feature of an adjustable chuck, which is often used to abut and fix the clamped microphone through a nut. When the microphone needs to be adjusted, the nut needs to be adjusted manually, so it is inconvenient to use. For this problem, the prior art provides many solutions, such as the fixture for a cylindrical body and a microphone bracket disclosed in JP5715912B2. The solution provided by this patent can easily install and remove the microphone with one touch, and can be reliably maintained, but it is not enough for the user's comfort compared to the convenient removal of the microphone. Therefore, there is still room for change and improvement in this field.

[0006] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application. Summary of the invention

[0007] The object of the present invention is to provide a support structure for a sound collection device, which can improve the convenience of disassembly and assembly of the microphone, avoid noise during the process of taking and placing the microphone and noise during use, and at the same time, the solution of the present invention can ensure free adjustment of the range of motion of the microphone and improve user comfort.

[0008] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: a support structure for a sound collection device, comprising: A limit assembly, on which a microphone is detachably mounted. A second support rod, the second support rod is connected to the limit assembly, The limiting assembly includes a limiting base, the limiting base abuts against the outer wall of the microphone, a first limiting ring plate arranged in an arc shape is arranged on the outer side of the limiting base, a first limiting connecting pin is arranged on the side of the limiting base, and 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 spacing distance with the limiting base; The limiting base comprises two arc-shaped limiting arc plates which are arranged opposite to each other. The two limiting arc plates are connected by a second limiting connecting pin, and a swingable tensioning adjustment plate is connected to the second limiting connecting pin at the end of the limiting arc plate.

[0009] The support structure for the sound collection device of the present invention has obvious advantages. The present invention adopts a limiting base to abut against the microphone to ensure effective contact with the microphone, which is conducive to the stable effect of placing the microphone on the support structure. On this basis, the present invention adopts a swingable tensioning adjustment plate to further limit the contact with the microphone, and the tensioning adjustment plate can swing relative to the limiting arc plate, so that the user can directly place the microphone on the limiting base and the tensioning adjustment plate automatically adjusts the tension of the microphone according to the diameter of the microphone. When removing the microphone, it can be directly lifted, and the lifting force is greater than the limiting force of the tensioning adjustment plate. In this way, the convenience of disassembly and assembly of the microphone is improved, and it is ensured that the present support structure is suitable for microphones of different specifications. More importantly, the limiting assembly of the present invention realizes the direct lifting and placement of the microphone on the support structure, effectively reducing and avoiding the possibility of collision between the microphone and the support structure or the limiting assembly, so that the noise and collision noise generated by the microphone lifting or turning process can be effectively avoided during the user's use, especially the noise in the use of performances and recording scenes.

[0010] In addition, for the vibration generated by the microphone placed on the support structure during use, its vibration energy can be consumed by the metal wire wrapped between a limit ring plate and a limit base, which can effectively avoid the vibration of the microphone when it is placed. The design of the metal wire also facilitates the user's hand to quickly locate the limit component and adjust the inclination angle of the inner microphone through the deformation of the metal wire to ensure free adjustment of the microphone's range of motion, thereby improving user comfort.

[0011] According to one embodiment of the present invention, the side surface of the tensioning 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 is pressed downward to abut against the surface of the limiting arc plate. At the same time, the downward pressure drives the lower part of the tensioning adjustment plate to swing downward, thereby realizing that the microphone is placed on the limiting arc plate at one time, and when the lower part of the tensioning adjustment plate swings downward, its upper part swings along with the swing, thereby realizing limiting abutment with the part of the limiting arc plate that does not contact the microphone. The design of enabling the side surface of the tensioning adjustment plate to abut against the adjacent surface of the limiting arc plate can eliminate or avoid the arbitrary rotation of the tensioning adjustment plate affecting the placement and taking of the microphone.

[0012] According to one embodiment of the present invention, a limiting support link is further connected between the two limiting arc plates, and the first limiting connection pins are respectively arranged on the outer side of the limiting arc plates. Since the second limiting connection pin is arranged between the two limiting arc plates, the spacing between the two limiting arc plates can be realized, but the spacing between the limiting arc plates may vary in the area where the second limiting connection pin is not arranged, which is not conducive to maintaining the contact between the entire limiting base body and the microphone. The limiting support link is designed to ensure that the spacing between the two limiting arc plates is controllable.

[0013] According to one embodiment of the present invention, the tension adjustment plate includes an arc-shaped first tension plate and a second tension plate hinged to the first tension plate. A second limiting connecting ring is provided on one side of the first tensioning plate, and a first limiting connecting ring corresponding to the second limiting connecting ring is provided on the second tensioning plate adjacent to the first tensioning plate. The first limiting connecting ring and the second limiting connecting ring are connected by a limiting plug block, and a through hole is provided in the middle of the limiting plug block through which the second limiting connecting pin can pass.

[0014] The microphone is pressed downward and abuts against the surface of the limiting arc plate. At the same time, the downward pressure drives the first tensioning plate at the bottom of the tensioning adjustment plate to swing downward, so that the microphone is placed on the limiting arc plate at one time, and when the first tensioning plate at the bottom of the tensioning adjustment plate swings downward, the second tensioning plate at the top of the tensioning adjustment plate swings along with the swing to achieve limiting abutment against the part of the limiting arc plate that does not contact the microphone. In this way, the convenience of disassembly and assembly of the microphone is improved, and it is ensured that the support structure is suitable for microphones of different specifications, and the possibility of collision between the microphone and the support structure or the limiting component is effectively reduced and avoided.

[0015] According to one embodiment of the present invention, the opposing surfaces of the first tensioning plate and the second tensioning plate are both provided with corresponding limit hole bodies, a first rubber column is inserted in the limit hole body, a through groove is opened on the first rubber column, through which the second limit connecting pin can pass and be displaced, a limit tensioning spring is also provided in the limit hole body, and the limit tensioning spring abuts against the end of the first rubber column. The first tensioning plate and the second tensioning plate arranged as mentioned above can ensure that the limiting arc plate does not contact the microphone part and are in limiting contact, wherein the first tensioning plate and the second tensioning plate are arranged by means of a tensioning spring and a first rubber column to achieve that the first tensioning plate and the second tensioning plate can bend relative to each other and restore elastic deformation, thereby achieving improved convenience in disassembly and assembly of the microphone. It should also be noted that during the use of the microphone, the surface of the microphone may be in contact with sweat remaining on the hand during use. At this time, the tensioning spring and the first rubber column expand the contact surface with the microphone and provide a tensioning and clamping effect, and the tensioning and clamping is to press downward from the upper part of the microphone to keep the microphone in continuous contact with the limiting arc plate, thereby solving the problem of the microphone slipping or shifting during placement due to the slippery surface.

[0016] According to one embodiment of the present invention, the second support rod is connected to the limit assembly through an adjustment component, and the adjustment component includes a third base sleeve, one side of the third base sleeve is detachably connected to the second base sleeve, one side of the third base sleeve is provided with a limit assembly hole, and the other side is provided with a threaded hole connected to the limit assembly hole, the third base sleeve is connected to the second base sleeve through a second fastener and a threaded hole, the second base sleeve is a column sleeve-shaped structure and its outer side is provided with a thread, the outer side of the second base sleeve is connected to the first base sleeve through a thread, the first base sleeve is through-set at both ends, a spherical adjustment ball is provided in the first base sleeve, the adjustment ball is connected to a rod body extending to the outside of the first base sleeve, and the rod body is connected to the first limit ring plate. The bottom of the first limit ring plate is provided with a plug-in connecting plate connected to the rod body, and the end of the rod body is provided with a slot hole and a fastener for plugging in the plug-in connecting plate. The end diameter of the spherical adjustment ball provided in the first base sleeve is reduced, and the end diameter is smaller than the diameter of the adjustment ball. By providing a second base sleeve, a third base sleeve and a limit assembly hole, the adjustment component can be disassembled and assembled, so that the accessories are easy to replace. By providing a spherical adjustment ball inside the first base sleeve, it can drive the existing limit ring plate to swing and rotate, thereby realizing the free adjustment range of the microphone in the placed state, which is convenient for users to use.

[0017] According to one embodiment of the present invention, the end of the second base sleeve is arranged inside the first base sleeve and a limiting clamping plate is provided at the end, a rubber base is provided between the limiting clamping plate and the upper adjusting ball, a protrusion is provided on the surface of the limiting clamping plate, a third fastener is connected to one side of the first base sleeve, the end of the third fastener is arranged inside the first base sleeve and corresponds to the horizontal height of the protrusion, and at least two steel balls are placed between the end of the third fastener and the protrusion.

[0018] The present invention controls the movable range of the steel ball by designing a limit clamp plate to facilitate adjustment, and at the same time, a third fastener is provided to realize the squeezing movement of the steel ball, so as to control the position of the steel ball after being compressed, and the continuous rotation and change of the third fastener causes the steel ball to squeeze the upper rubber base, and the rubber base is deformed to squeeze the upper adjusting sphere, and the swinging and rotation of the adjusting sphere is limited by the bottom rubber base, and there is friction between the adjusting sphere and the rubber base during the rotation process, which will not cause the adjusting sphere to swing at will or cause the position of the adjusting sphere to change due to the gravity of the microphone. In this way, when the upward displacement deformation of the bottom steel ball is too large, the adjusting sphere can be directly locked to prevent it from swinging and rotating, so as to control the rotation tightness of the adjusting sphere, and facilitate the user to adjust the free movable range of the microphone. At the same time, compared with the vibration generated by the free disassembly and assembly of the microphone on the limit assembly, the vibration transmitted to the rubber base can be blocked, so as to prevent the vibration from being transmitted downward to the second support rod below.

[0019] According to one embodiment of the present invention, a first fastener is threadedly connected to the side of the first base sleeve, and the horizontal height position is higher than the height of the top surface of the protrusion on the rubber base. The end of the first fastener is arranged inside the first base sleeve and abuts against the rubber base. The first fastener is designed to abut against one side of the rubber base, thereby ensuring that the rubber base always maintains contact with the adjusting ball, which is used to maintain the rotational tightness of the adjusting ball and avoid the adjusting ball from swinging and rotating randomly due to the lack of friction restriction of the rubber base.

[0020] According to one embodiment of the present invention, a second counterweight chassis is connected to the bottom of the second support rod, and a hinged mounting slot is opened around the second counterweight chassis. A hinged plate is arranged in the hinged mounting slot and is hinged to a limiting support rod. The second counterweight chassis and the limiting support rod are arranged to achieve the purpose of placing the second support rod stably on the ground, and the limiting support rod can be used to adapt to the ground with different flatnesses.

[0021] According to one embodiment of the present invention, a first bottom plate is provided at the bottom of the second counterweight chassis, and an articulated connection seat is arranged around the bottom of the second support rod. The limiting support rod can be connected to the articulated connection seat. By designing a connection scheme between the articulated connection seat and the limiting support rod, direct support for the second support rod is achieved, and a variety of support schemes for the second support rod are provided to ensure a stable effect during the use of the second support rod.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: the support structure for the sound collection device of the present invention has obvious advantages. The present invention adopts 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 adopts a swingable tensioning adjustment plate to further limit the contact with the microphone, and the tensioning adjustment plate can swing relative to the limiting arc plate, so that the user can directly place the microphone on the limiting base and the tensioning adjustment plate automatically adjusts the tension of the microphone according to the diameter of the microphone. When removing the microphone, it can be directly lifted up, and the lifting force is greater than the limiting force of the tensioning adjustment plate. In this way, the convenience of disassembly and assembly of the microphone is improved, and it is ensured that the present support structure is suitable for microphones of different specifications.

[0023] As described above, the method of the present invention is a method that can improve the convenience of disassembly and assembly of the microphone, avoid noise in the process of taking and placing the microphone and noise in the use process. At the same time, the solution of the present invention can ensure free adjustment of the range of movement of the microphone and improve the support structure of the sound collection device for user comfort.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described in detail below in conjunction with specific implementations and drawings: Example

[0027] A support structure for a sound collection device, as shown in the attached Figure 4 As shown, the support structure has a second support rod 60, and the diameter of the second support rod 60 is preferably φ2.5cm-φ20cm. The second support rod 60 can be a telescopic rod that can be extended and retracted. The telescopic rod is highly suitable for children and adults. The total telescopic length of the telescopic rod is between 0.5m-2.5m. Of course, under appropriate conditions, the total telescopic length can be adaptively extended or shortened.

[0028] A limiting assembly 30 is installed at the end of the second support rod 60 of the supporting structure. In this embodiment, the limiting assembly 30 is used to place the microphone 10.

[0029] What needs further description is: Figure 8 and attached Fig. 9 As shown, the limiting assembly 30 includes a limiting base 33, the limiting base 33 abuts against the outer wall of the microphone 10, a first limiting ring plate 31 arranged in an arc shape is arranged on the outer side of the limiting base 33, a first limiting connecting pin 34 is arranged on the side of the limiting base 33, and the first limiting ring plate 31 is connected to the first limiting ring plate 31 body and the first limiting connecting pin 34 by a metal wire 35 to form a spacing distance with the limiting base 33; The limiting base 33 includes two arc-shaped limiting arc plates 331 arranged opposite to each other. The two limiting arc plates 331 are connected by a second limiting connecting pin 333 , and a swingable tensioning adjustment plate 36 is connected to the second limiting connecting pin 333 at the end of the limiting arc plate 331 .

[0030] In the use of the microphone 10, especially in performance and recording scenes, the prior art generally uses a simple support frame to place the microphone 10. Some support frames have an adjustable height function, which takes into account the height of the user. The microphone 10 is generally placed by clamping it with a clip-like structure or using a nut to abut the microphone 10.

[0031] In comparison, the support structure for the sound collection device of the present invention has obvious advantages. The present invention adopts a limiting base 33 to abut against the microphone 10 to ensure effective contact with the microphone 10, which is beneficial to the stability of the microphone placed on the support structure. On this basis, the present invention adopts a swingable tensioning adjustment plate 36 to further limit the contact with the microphone 10, and the tensioning adjustment plate 36 can swing relative to the limiting arc plate 331, so that the user can directly place the microphone 10 on the limiting base 33 and the tensioning adjustment plate 36 automatically adjusts the tension of the microphone 10 according to the diameter of the microphone 10, and moves When removing the microphone 10, it only needs to be lifted up directly, and the lifting force is greater than the limiting force of the tensioning adjustment plate 36. This improves the convenience of disassembly and assembly of the microphone, and ensures that the support structure is suitable for microphones of different specifications. More importantly, the limiting assembly of the present invention enables the microphone 10 to be directly lifted up and placed on the support structure, effectively reducing and avoiding the possibility of collision between the microphone 10 and the support structure or the limiting assembly 30. In this way, the noise and collision noise generated during the lifting or adjustment process of the microphone 10 can be effectively avoided during the user's use, especially the noise generated during use in performances and recording scenes.

[0032] In addition, for the vibration generated by the microphone 10 placed on the support structure during use, its vibration energy can be consumed by the metal wire 35 wrapped between a limit ring plate 31 and a limit base 33, which can effectively avoid the vibration of the microphone when it is placed. The design of the metal wire 35 also facilitates the user's hand to quickly locate the limit assembly 30 and adjust the inclination angle of the inner microphone 10 through the deformation of the metal wire 35 to ensure free adjustment of the microphone's range of motion, thereby improving user comfort.

[0033] It should be noted that an audio collection device is disposed at the main end of the microphone and connected to the microphone. The audio collection device has a sound pickup unit and an amplifying circuit, which belongs to the prior art and will not be described in detail in the present invention.

[0034] As attached Fig. 9 As shown, the side surface of the tensioning 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 is pressed downward to abut against the surface of the limiting arc plate 331. At the same time, the downward pressure drives the lower part of the tensioning adjustment plate 36 to swing downward, thereby realizing that the microphone 10 is placed on the limiting arc plate 331 at one time, and when the lower part of the tensioning adjustment plate 36 swings downward, its upper part swings along with the swing to achieve limiting abutment on the part of the limiting arc plate 331 that does not contact the microphone 10. The design of allowing the side surface of the tensioning adjustment plate 36 to abut against the adjacent surface of the limiting arc plate 331 can eliminate or avoid the arbitrary rotation of the tensioning adjustment plate 36 affecting the placement and taking of the microphone 10.

[0035] As attached Fig.10 As shown, in this embodiment: a limiting support link 332 is also connected between the two limiting arc plates 331, and the first limiting connection pins 34 are respectively arranged on the outer side of the limiting arc plates 331. Since the second limiting connection pin 333 is provided between the two limiting arc plates 331, the spacing distance between the two limiting arc plates 331 can be achieved, but the spacing between the limiting arc plates 331 may vary in the area where the second limiting connection pin 333 is not provided, which is not conducive to maintaining the contact between the entire limiting base 33 and the microphone 10. The limiting support link 332 is designed to ensure that the spacing between the two limiting arc plates 331 is controllable.

[0036] The tensioning adjustment plate 36 includes an arc-shaped first tensioning plate 361 and a second tensioning plate 365 hinged to the first tensioning plate 361. A second limiting connecting ring 367 is provided on one side of the first tensioning plate 361, and a first limiting connecting ring 364 corresponding to the second limiting connecting ring 367 is provided on the second tensioning plate 365 adjacent to the first tensioning plate 361. The first limiting connecting ring 364 and the second limiting connecting ring 367 are connected by a limiting plug block 362, and a through hole is provided in the middle of the limiting plug block 362, through which the second limiting connecting pin 333 can pass.

[0037] The microphone 10 is pressed downward and abuts against the surface of the limiting arc plate 331. At the same time, the downward pressure drives the first tensioning plate 361 at the bottom of the tensioning adjustment plate 36 to swing downward, so that the microphone 10 is placed on the limiting arc plate 331 at one time, and when the first tensioning plate 361 at the bottom of the tensioning adjustment plate 36 swings downward, the second tensioning plate 365 at the top thereof swings along with it to limit and abut against the part of the limiting arc plate 331 that does not contact the microphone 10. In this way, the convenience of disassembly and assembly of the microphone 10 is improved, and it is ensured that the support structure is suitable for microphones of different specifications, and the possibility of collision between the microphone 10 and the support structure or the limiting assembly 30 is effectively reduced and avoided.

[0038] As attached Fig.10 and attached Fig.11 As shown, the opposing surfaces of the first tensioning plate 361 and the second tensioning plate 365 are provided with corresponding position limit holes 368, in which the first rubber column 366 is inserted, and the first rubber column 366 is provided with a through groove through which the second limit connecting pin 333 can pass and move, and the limit tensioning spring 363 is also provided in the limit hole 368, and the limit tensioning spring 363 abuts against the end of the first rubber column 366. The first tensioning plate 361 and the second tensioning plate 365 provided as above can ensure that the limiting arc plate 331 does not contact the part of the microphone 10 for limiting contact, wherein the first tensioning plate 361 and the second tensioning plate 365 are provided with a tensioning spring 363 and a first rubber column 366 to achieve that the first tensioning plate 361 and the second tensioning plate 365 can bend relative to each other and restore elastic deformation, thereby achieving improved convenience in disassembly and assembly of the microphone 10. It should also be noted that during the use of the microphone 10, the surface of the microphone 10 may be in contact with sweat from the hands during use. At this time, the tensioning spring 363 and the first rubber column 366 are provided to expand the contact surface with the microphone 10 and provide a tensioning and clamping effect, and the tensioning and clamping is to press downward from the upper part 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 the slippery surface.

[0039] This embodiment further provides the following solution based on embodiment 1: Fig.12As shown, the second support rod 60 is connected to the limit assembly 30 through the adjustment assembly 40, and the adjustment assembly 40 includes a third base sleeve 46, and the third base sleeve 46 is detachably connected to the second base sleeve 45 on one side, and a limit assembly hole 47 is provided on one side of the third base sleeve 46, and a threaded hole connected to the limit assembly hole 47 is provided on the other side, and the third base sleeve 46 is connected to the second base sleeve 45 through a second fastener 48 and the threaded hole, and the second base sleeve 45 is a column sleeve structure and has a thread on the outside, and the second base sleeve 45 is connected to the first base sleeve 42 through the thread on the outside, and the first base sleeve 42 is through-set at both ends, and a spherical adjustment ball 41 is provided in the first base sleeve 42, and the adjustment ball 41 is connected to a rod body extending to the outside of the first base sleeve 42, and the rod body is connected to the first limit ring plate 31. The bottom of the first limit ring plate 31 is provided with a plug-in connecting plate 32 connected to the rod body, and the end of the rod body is provided with a plug-in slot and a fastener for plugging with the plug-in connecting plate 32. The first base sleeve 42 is provided with a spherical adjusting ball 41 whose end diameter is reduced, and the end diameter is smaller than the diameter of the adjusting ball 41. The adjusting assembly 40 can be disassembled and assembled by arranging the second base sleeve 45, the third base sleeve 46 and the limit assembly hole 47, so that the accessories are easy to replace. By arranging the spherical adjusting ball 41 inside the first base sleeve 42, it can drive the existing limit ring plate 31 to swing and rotate, thereby realizing the free adjustment range of the microphone 10 in the placed state, which is convenient for users to use.

[0040] As attached Fig.12 As shown, the end of the second base sleeve 45 is arranged inside the first base sleeve 42 and a limit clamping plate 44 is arranged at the end, a rubber base 411 is arranged between the limit clamping plate 44 and the upper adjusting ball 41, a protrusion is arranged on the surface of the limit clamping plate 44, a third fastener 410 is connected to one side of the first base sleeve 42, the end of the third fastener 410 is arranged inside the first base sleeve 42 and corresponds to the horizontal height of the protrusion, and 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 plane, the rubber base 411 has an annular structure, and one side of the annular structure is sealed, and the sealing surface is arranged adjacent to the limit clamping plate 44.

[0041] The present invention controls the movable range of the steel ball 49 by designing a limit clamp 44 to facilitate adjustment, and at the same time, a third fastener 410 is provided to realize the squeezing movement of the steel ball 49, thereby controlling the position of the steel ball 49 after being compressed. The third fastener 410 continuously rotates and changes to make the steel ball 49 squeeze the upper rubber base 411, and the rubber base 411 deforms to squeeze the upper adjustment ball 41. The swinging rotation of the adjustment ball 41 is limited by the rubber base 411 at the bottom, and there is friction between the adjustment ball 41 and the rubber base 411 during the rotation process. This will not cause the adjusting sphere 41 to swing randomly or cause the position of the adjusting sphere 41 to change due to the gravity of the microphone 10. In this way, when the upward displacement deformation of the bottom steel ball 49 is too large, the adjusting sphere 41 can be directly locked, so that it cannot swing and rotate. In this way, the rotation tightness of the adjusting sphere 41 is controlled, which is convenient for the user to adjust the free range of movement of the microphone 10. At the same time, compared with the vibration generated by the free disassembly and assembly of the microphone 10 on the limit assembly 30, the vibration transmitted to the rubber base 411 can be blocked, thereby preventing the vibration from being transmitted downward to the second support rod 60 below.

[0042] The first base sleeve 42 is threadedly connected to a first fastener 43 at a horizontal height higher than the top surface of the protrusion on the rubber base 411. The end of the first fastener 43 is arranged 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, thereby ensuring that the rubber base 411 always maintains contact with the adjusting ball 41, and is used to maintain the rotational tightness of the adjusting ball 41, thereby avoiding the adjusting ball 41 from swinging and rotating randomly due to the lack of friction restriction of the rubber base 411.

[0043] As attached Fig.13 As shown, the bottom of the second support rod 60 is connected to the second counterweight chassis 70, and the second counterweight chassis 70 is surrounded by hinged mounting slots 75. A hinge plate is arranged in the hinged mounting slot 75 and a limited support rod 72 is hingedly arranged. The second counterweight chassis 70 and the limited support rod 72 are arranged to achieve the purpose of placing the second support rod 60 stably on the ground, and the limited support rod 72 can be used to adapt to the ground with different flatness.

[0044] A first bottom plate 71 is provided at the bottom of the second counterweight chassis 70, and an articulated connection seat 73 is arranged around the bottom of the second support rod 60. The limiting support rod 72 can be connected to the articulated connection seat 73. By designing a connection scheme between the articulated connection seat 73 and the limiting support rod 72, direct support for the second support rod 60 is achieved, and a variety of support schemes for the second support rod 60 are provided to ensure the stability of the second support rod 60 during use. Example

[0045] See attached Figure 4 As shown, a shock absorbing assembly 50 is provided on the second support rod 60, and the shock absorbing assembly 50 includes a first base body 56 of a column sleeve-shaped structure, and the first base body 56 is surrounded by first openings 57, and the inner wall of the first base body 56 is surrounded by a limiting insert 58, and the limiting insert 58 is arranged parallel to the axis of the column sleeve of the first base body 56, and the bottom end of the limiting insert 58 is fixedly connected to the inner wall of the first base body 56, and the first base body 56 is arranged adjacent to the first opening 57.

[0046] A first connecting column 53 is inserted into the first base 56, and the first connecting column 53 is coaxially arranged with the axis of the column sleeve of the first base 56. Two second connecting columns 55 arranged parallel to each other are connected to the bottom surface of the first connecting column 53. The second connecting column 55 is arranged parallel to the axis of the first connecting column 53. A circular flexible ring 54 is sleeved on the second connecting column 55, and the second connecting column 55 is provided with a mounting groove for limiting the displacement of the flexible ring 54 on the second connecting column 55, and the flexible ring 54 can be sleeved with the limiting insert 58.

[0047] The first connecting ring 51 is threadedly connected to one end of the first base 56, and a second assembly hole 52 is opened in the middle of the first connecting ring 51. The first connecting column 53 can pass through the second assembly hole 52 to connect with the second support rod 60 or the limit assembly hole 47 on the upper part. The other end of the first base 56 has a reduced diameter and is provided with a second assembly hole 510 that can be connected to the second support rod 60. A shock-absorbing ring body 59 that can be plugged into the end of the second support rod 60 is also provided inside the first base 56 at the end of the second assembly hole 510. The shock-absorbing ring body 59 is preferably made of rubber.

[0048] As above Figure 4 As shown, the present invention provides a shock absorbing assembly 50, which is installed on a second support rod 60. The optional shock absorbing assembly 50 can be installed with the second support rod 60 at the upper and lower ends, respectively, so that it is easy to disassemble and assemble the second support rod 60 and provide different use heights.

[0049] The second connecting column 55 of the shock absorbing assembly 50 provided in the present invention is provided with a flexible ring 54, and a limiting insert 58 is arranged around the inside of the first base sleeve 56, so that the flexible ring 54 can be sleeved on the limiting insert 58. For the external vibration transmitted to the first base sleeve 56 or the first connecting column 53, the vibration energy can be consumed in the process of deformation of the flexible ring 54 relative to the limiting insert 58. In particular, in the process of performance or recording, when a person or an 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 in the process of deformation of the flexible ring 54 relative to the limiting insert 58, so as to solve the problem that the vibration of the second support rod 60 is transmitted to the upper microphone 10 and the vibration is converted into an electrical signal to form noise. At the same time, the first connecting column 53 of the shock absorbing assembly 50 is limited by the first connecting ring 51 to ensure its up and down displacement, so as to ensure the vertical stability of the components connected to the upper part of the first connecting column 53 in the collision state without shaking, that is, effectively ensure the vertical stability of the microphone 10 in the collision state of the second support rod 60. Example

[0050] See attached Fig.14 As shown, the second support rod 60 is connected to a wind shield 80 via a connecting plate. The wind shield 80 is vertically arranged on one side of the microphone 10. The wind shield 80 is designed to prevent wind noise from affecting the use effect of the microphone 10 during use.

[0051] The above embodiments are only used to illustrate the present invention, but not to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention, and the patent protection scope of the present invention shall be defined by the claims.
