Description

Technical Field

[0001] This utility model relates to the field of microphone mounting bracket technology, and in particular to a rotatable microphone mounting bracket with noise reduction function. Background Technology

[0002] In the field of audio acquisition and transmission, microphone mounts are key auxiliary devices that ensure stable microphone operation and improve audio quality. They are widely used in scenarios such as live-streaming e-commerce, professional recording, conference presentations, and online teaching. Their core function is not only to provide stable support and flexible angle adjustment for the microphone, but also to work with the microphone to achieve clear sound pickup and avoid the impact of external interference on audio quality. As users' demands for audio purity continue to increase, especially in non-professional acoustic environments such as homes, offices, and outdoors, the noise reduction performance and stability of microphone mounts have become important factors affecting audio acquisition results.

[0003] Currently, the mainstream rotatable microphone holders in the industry mainly achieve angle adjustment and microphone fixation through metal or plastic rods and clamping structures, but they have obvious shortcomings in applicability and cannot meet diverse usage needs.

[0004] First, existing clamping structures mostly use snap-on or spring-loaded designs, requiring manual prying of the clamping arms for adjustment. This is not only laborious but also makes it difficult to precisely control the clamping force. Too loose a force can cause the microphone to shift or slip during use, while too tight a force may crush the microphone shell, affecting its lifespan. Furthermore, they are incompatible with microphones of different diameters, resulting in poor versatility. Second, the contact between the clamping structure and the microphone is often rigid, making the bracket susceptible to minor external vibrations. These vibrations are directly transmitted to the microphone body through the clamping area, transforming into additional low-frequency noise (such as "humming" and "buzzing" sounds). This noise, combined with the target sound, further degrades audio quality. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rotatable microphone mounting bracket with noise reduction function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rotatable microphone mounting bracket with noise reduction function, comprising a mounting frame and a microphone body, wherein an adjustment groove is provided at the bottom inner part of the mounting frame, a screw is rotatably mounted in the middle of the adjustment groove, and the other end of the screw extends through to the outside of the mounting frame and is fixedly mounted with a knob;

[0007] The screw has a threaded connection to a screw hole block. Both ends of the screw hole block have grooves. A drive plate is hinged to the inner side of each groove. A bending plate is hinged to the other end of each drive plate. A clamping plate is provided at the other end of each bending plate. The microphone body is located between the two clamping plates. An arc-shaped groove is provided on the inner side of each clamping plate, and a buffer pad is fixedly installed on the inner side of the arc-shaped groove. The inner side of the buffer pad fits against the middle of the microphone body. Multiple round holes are opened through the interior of the buffer pad. A fixing plate is fixedly installed on the upper end of the mounting bracket. A microphone cover is fixedly installed on the other end of the fixing plate.

[0008] Preferably, the microphone cover is horn-shaped and fitted onto the sound-receiving part of the microphone body, and the microphone cover is made of ABS engineering plastic.

[0009] Preferably, both clamping plates have rectangular grooves on the side near the bending plate, and the side of the bending plate away from the driving plate is hinged to the inside of the rectangular groove.

[0010] Preferably, a pin is fixedly installed at the bending position in the middle of the bending plate, and the upper and lower ends of the pin are respectively rotatably installed on the upper and lower surfaces inside the adjusting groove.

[0011] Preferably, the included angle at the connection between the drive plate and the bending plate is 160°. When the screw hole block moves closer to the clamping plate, it causes the two drive plates to move closer to the screw, and drives the bending plate to move the clamping plate to unfold to both sides.

[0012] Preferably, the mounting bracket has a connecting seat at the bottom, a lifting rod is fixedly installed at the bottom of the connecting seat, and a connecting groove is provided at the upper end of the connecting seat.

[0013] Preferably, through holes are provided on both sides of the upper end of the connecting groove, and a sleeve is rotatably provided on the inner side of the through hole. The sleeve has a threaded groove inside, and a fixing screw is provided on the outer side of the connecting seat.

[0014] Preferably, the fixing screw is connected to the internal thread of the sleeve through a through hole, and a hexagonal groove is provided on the outer side of the fixing screw. A connecting plate is fixedly installed at the bottom of the mounting bracket, and the bottom of the connecting plate is fixedly installed in the middle of the sleeve.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. This utility model achieves stable adaptation and precise fixation of microphones of different diameters through a knob-type adjustable clamping structure. The knob drives the screw to rotate synchronously, and the rotation of the screw drives the screw hole block to move along the screw axis. When the screw hole block moves, the drive plates hinged in the grooves at both ends of the screw hole block move accordingly. The drive plates drive the bending plate to rotate around the pin as the fulcrum, thereby enabling the clamping plate connected to the other end of the bending plate to open and close. This not only avoids the microphone from shifting and slipping due to excessive force, but also prevents the microphone shell from being squeezed due to excessive force. At the same time, it can adapt to microphones of different diameters, greatly improving the versatility and ease of use of the bracket, and providing basic support for the stable operation of the microphone.

[0017] 2. This utility model installs a buffer pad on the inner side of the two clamping plates. The inner side of the buffer pad is tightly fitted to the middle of the microphone body. The buffer pad first absorbs vibration energy by means of the damping characteristics of its own rubber material. At the same time, the multiple round holes inside form an independent deformation space. When the vibration wave acts on the buffer pad, the round holes will undergo elastic deformation, further dispersing and weakening the vibration energy, preventing the vibration from being directly transmitted to the microphone body through the clamping plates. This effectively reduces the interference of vibration on the microphone's sound receiving element, ensuring the purity of audio acquisition. In addition, the opening design on the buffer pad enhances the deformation capability of the buffer pad, avoiding the degradation of shock absorption performance after long-term use of solid rubber pads, and extending the service life of the buffer pad.

[0018] 3. This utility model uses a microphone cover to fix the microphone to the upper end of the mounting bracket, and the microphone cover is fitted onto the sound-receiving part of the microphone body. The microphone cover has a funnel-shaped structure with a large opening facing the sound source and a small opening connecting to the microphone head. When the microphone collects sound, the target sound enters through the large opening of the microphone cover, is guided by the inner wall of the cover, and is concentrated and directed to the microphone head, thereby improving the collection intensity of the target sound. At the same time, the side wall of the microphone cover will block ambient noise from the side and rear from entering the sound-receiving area, weakening the interference of ambient noise and greatly improving the signal-to-noise ratio of the output audio.

[0033] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0034] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0035] Example: Reference Figures 1-5 A rotatable microphone mounting bracket with noise reduction function includes a mounting frame 1 and a microphone body 2. An adjustment groove 4 is provided on the inner bottom of the mounting frame 1. A screw 5 is rotatably installed in the middle of the adjustment groove 4. The other end of the screw 5 extends through to the outside of the mounting frame 1 and is fixedly installed with a knob 501.

[0036] The screw 5 has a threaded connection to a screw hole block 6. Both ends of the screw hole block 6 have grooves 601. The inner sides of the two grooves 601 are hinged to drive plates 605. The other ends of the two drive plates 605 are hinged to bend plates 602. The other ends of the two bend plates 602 are provided with clamping plates 603. The microphone body 2 is located between the two clamping plates 603. The inner sides of the two clamping plates 603 have arc-shaped grooves, and the inner sides of the arc-shaped grooves are fixedly installed with buffer pads 7. The inner side of the buffer pads 7 fits against the middle of the microphone body 2. The interior of the buffer pads 7 has multiple through holes 701. The upper end of the mounting bracket 1 is fixedly installed with a fixing plate 8. The other end of the fixing plate 8 is fixedly installed with a microphone cover 801.

[0037] Specifically: In actual use, the flat structure of the upper and lower surfaces of the adjustment groove 4 ensures that the bending plate 602 maintains a stable trajectory when rotated by the pin 606. One end of the screw 5 is fixed to the knob 501, and the middle part is threaded into the screw hole block 6. The other end is rotatably installed on the protruding fixing point inside the adjustment groove 4, which can convert the rotational force of the knob 501 into the linear motion of the screw hole block 6. One end of the drive plate 605 is hinged to the screw hole block 6, and the other end is hinged to the bending plate 602, which can convert the linear motion of the screw hole block 6 into the rotational motion of the bending plate 602 around the pin 606, thereby indirectly adjusting the clamping force. The buffer pad 7 is designed to absorb the vibration energy transmitted from the outside to the clamping plate 603 by utilizing the damping characteristics of the rubber material. The multiple through holes 701 inside the buffer pad 7 can further expand the deformation space of the buffer pad 7 and enhance the dispersion and weakening effect of vibration waves.

[0038] During adjustment, the operator rotates knob 501, causing screw 5 to rotate synchronously within adjustment groove 4. Screw hole block 6 moves along the axis of screw 5 under the action of the screw thread. When screw hole block 6 moves, drive plates 605 in grooves 601 at both ends rotate accordingly, thereby causing bending plate 602 to rotate around pin 606. During the rotation of bending plate 602, clamping plate 603 moves closer to or away from microphone body 2, thus clamping and fixing or releasing the microphone. After clamping and fixing, buffer pad 7 on the inner side of clamping plate 603 fits tightly against microphone body 2, which can absorb external vibrations in real time. The microphone cover 801 is stably fitted onto the microphone's sound receiving part through fixing plate 8, simultaneously playing the role of gathering target sound and blocking environmental noise, ultimately achieving stable clamping and efficient noise reduction of the microphone.

[0039] The microphone cover 801 is horn-shaped and is fitted onto the microphone body 2. The microphone cover 801 is made of ABS engineering plastic. Rectangular grooves 604 are provided on the side of the two clamping plates 603 near the bending plate 602. The side of the bending plate 602 away from the driving plate 605 is hinged to the inside of the rectangular groove 604. A stabilizing rod is rotatably provided on the side of the rectangular groove 604 away from the bending plate 602. The stabilizing rod and the side of the bending plate 602 near the clamping plate 603 are kept parallel. The side of the stabilizing rod away from the clamping plate 603 is rotatably installed on the inside of the adjustment groove 4. A pin 606 is fixedly installed at the bending position in the middle of the bending plate 602. The upper and lower ends of the pin 606 are rotatably installed on the upper and lower surfaces inside the adjustment groove 4, respectively.

[0040] Specifically: The stabilizing rod rotatably installed inside the rectangular groove 604 is parallel to the side of the bending plate 602 near the clamping plate 603, and the end of the stabilizing rod away from the clamping plate 603 is rotatably installed inside the adjusting groove 4, forming a parallelogram support structure. This structure can limit the movement trajectory of the clamping plate 603 when the bending plate 602 drives the clamping plate 603 to open and close, prevent the clamping plate 603 from shifting laterally or tilting, and ensure that the clamping plate 603 always moves smoothly in the preset direction, thereby ensuring the accurate clamping position of the microphone body 2.

[0041] In actual operation, when the drive plate 605 drives the bending plate 602 to rotate around the pin 606, the bending plate 602 drives the clamping plate 603 to move through the rectangular groove 604. At this time, the stabilizing rod rotates synchronously, always maintaining a parallel support state, ensuring that the clamping plate 603 stably clamps the microphone body 2. At the same time, the microphone cover 801, with the help of the horn-shaped structure and the characteristics of ABS material, simultaneously completes the target sound gathering and environmental noise blocking. The various structures cooperate with each other to achieve stable fixation of the microphone and ensure noise reduction effect during the sound recording process.

[0042] The angle between the drive plate 605 and the bending plate 602 is 160°. During the movement of the screw block 6, the drive plates 605 at both ends are pulled towards the screw 5. At this time, the 160° angle between the drive plate 605 and the bending plate 602 allows the driving force to be smoothly transmitted to the bending plate 602, causing the bending plate 602 to rotate around the pin 606 and drive the clamping plate 603 to unfold to both sides. After the microphone is placed between the two clamping plates 603, the knob 501 is turned in the opposite direction to move the screw block 6 away from the clamping plate 603. The drive plate 605 then spreads to both sides, pulling the bending plate 602 to rotate in the opposite direction, thereby driving the clamping plate 603 to move towards the middle and clamp the microphone. The screw block 6 moves towards the clamping plate 603. When they approach each other, the two drive plates 605 move closer to the screw 5, driving the bending plate 602 to expand the clamping plate 603 to both sides. Since the screw hole block 6 and the screw 5 are threadedly engaged, when the screw 5 rotates under the action of the knob 501, the screw hole block 6 will move along the axis of the screw 5 towards the clamping plate 603. During this process, the parts at both ends of the screw hole block 6 that are hinged to the drive plates 605 move synchronously, thereby generating a pulling force on the drive plates 605 in the direction of the screw 5, causing the two drive plates 605 to gradually move closer to the screw 5. Through the hinge relationship between the drive plates 605 and the bending plate 602, the linear pulling force is converted into the rotational power of the bending plate 602, providing direct drive for the expansion of the clamping plate 603.

[0043] The mounting bracket 1 has a connecting seat 101 at its bottom, and a lifting rod 102 is fixedly installed at the bottom of the connecting seat 101. A connecting groove 3 is opened at the upper end of the connecting seat 101. Through holes are opened on both sides of the upper end of the connecting groove 3, and a sleeve 301 is rotatably installed inside the through hole. A threaded groove is opened inside the sleeve 301. A fixing screw 303 is provided on the outer side of the connecting seat 101. The fixing screw 303 is connected to the internal thread of the sleeve 301 through the through hole. A hexagonal groove is opened on the outer side of the fixing screw 303. A connecting plate 302 is fixedly installed at the bottom of the mounting bracket 1. The bottom of the connecting plate 302 is fixedly installed in the middle of the sleeve 301.

[0044] Specifically: In actual use, when the height of the bracket needs to be adjusted, the entire bracket is adjusted to the appropriate height and fixed by the telescopic structure of the lifting rod 102; when the microphone pickup angle needs to be adjusted, first loosen the fixing screw 303 so that the sleeve 301 can rotate freely in the through hole of the connecting groove 3, then push the mounting bracket 1 to drive the connecting plate 302 and the sleeve 301 to rotate synchronously until the microphone turns to the appropriate pickup direction, and finally tighten the fixing screw 303 with a hexagonal tool so that the fixing screw 303 locks with the sleeve 301 through the thread, restricting the rotation of the sleeve 301, thereby fixing the angle of the mounting bracket 1; the various structures cooperate with each other to achieve flexible adjustment of the bracket height and microphone angle, and ensure the stability of the structure after adjustment, providing support for stable microphone pickup.

[0045] The working principle of this utility model is as follows: In specific use, firstly, the connecting plate 302 at the bottom of the mounting bracket 1 is embedded into the connecting groove 3 of the connecting seat 101, so that the connecting plate 302 is fixedly connected to the sleeve 301 inside the connecting groove 3. After adjusting the angle of the microphone body 2, the fixing screw 303 on the outside of the connecting seat 101 is rotated by a hexagonal tool, so that the fixing screw 303 is tightened along the thread groove inside the sleeve 301, thereby achieving stable fixation between the mounting bracket 1 and the connecting seat 101. Then, according to the usage scenario requirements, the extension length of the lifting rod 102 at the bottom of the connecting seat 101 is adjusted to adjust the entire bracket to the appropriate sound receiving height.

[0046] Next, the operator rotates the knob 501 on the outside of the mounting bracket 1. The knob 501 drives the screw 5 in the adjusting groove 4 to rotate synchronously. Since the screw 5 and the screw hole block 6 are threadedly connected, the rotation of the screw 5 will drive the screw hole block 6 to move away from the knob 501 along the axis of the screw 5. When the screw hole block 6 moves, the drive plates 605 hinged in the grooves 601 at both ends of the screw hole block 6 will move accordingly. Since the other end of the drive plate 605 is hinged to the bending plate 602, the drive plate 605 will drive the bending plate 602 to move with the pin 606 as the support. The point is rotated outward, causing the clamping plate 603 connected to the other end of the bending plate 602 to unfold synchronously; at this time, the microphone body 2 is placed between the two clamping plates 603 through the upper sound-receiving cover 801, and the knob 501 is rotated in the opposite direction, causing the screw hole block 6 to move towards the side closer to the knob 501. The driving plate 605 pulls the bending plate 602 to rotate inward, causing the clamping plate 603 to gradually clamp the microphone until the buffer pad 7 on the inner side of the clamping plate 603 is tightly attached to the middle of the microphone body 2, thus completing the stable fixation of the microphone.

[0047] During use, the horn-shaped microphone cover 801 fixed at the upper end of the mounting bracket 1, because it is fitted onto the microphone's sound-receiving part, can concentrate the target sound and guide it to the microphone's sound-receiving head. At the same time, it blocks ambient noise from the side and rear through the side wall. Combined with the sound insulation performance of the ABS engineering plastic material, it reduces the interference of ambient noise on the microphone's sound reception and ensures the purity of the audio acquisition.
