[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.
[0020] like Figures 1-8 The microporous waterproof condenser microphone shown includes a mounting ring 1, on which multiple mounting mechanisms 2 are fixedly connected, a headlight 3 is sleeved inside the mounting ring 1, a protective cover 4 is fixedly connected to one side of the mounting ring 1, and the bottom opening of the protective cover 4 is symmetrically structured and rotatably connected with two baffles 5, a movable ring 6 is provided inside the protective cover 4, a rotating ring 7 is rotatably connected to the movable ring 6, and a condenser microphone 8 is rotatably connected to the rotating ring 7.
[0021] like Figure 3 As shown, an adjustment ring 101 is rotatably connected to the mounting ring 1, an annular rack A102 is fixedly connected to the adjustment ring 101, and a shift lever 103 is fixedly connected to the adjustment ring 101. The shift lever 103 is used to rotate the adjustment ring 101, so that the adjustment ring 101 drives the connected annular rack A102, and the annular rack A102 drives the driving wheel 203 to rotate.
[0022] like Figure 4 As shown, the mounting mechanism 2 includes a fixed seat 201, which is fixedly connected to the mounting ring 1. A threaded sleeve 202 is rotatably provided on the fixed seat 201, and a driving wheel 203 is fixedly connected to the outer wall of the threaded sleeve 202. The driving wheel 203 is meshed with the annular rack A102 for transmission.
[0023] A guide rod 204 is provided through the fixing base 201 in a sliding manner. A mounting rod 205 is fixedly connected to the bottom end of the guide rod 204. The mounting rod 205 abuts the outer wall of the headlamp 3. A threaded rod 206 is fixedly connected to the mounting rod 205 and is threadedly connected to the threaded sleeve 202. The driving wheel 203 drives the threaded sleeve 202 to rotate, which in turn drives the threaded rod 206 to move, driving the mounting rod 205 to abut against the headlamp 3 for fixation.
[0024] like Figure 5 As shown, a worm gear 501 is fixedly connected to one end of the baffle 5. A worm 502 is meshingly provided on one side of the worm gear 501. The bottom end of the worm gear 502 is rotatably connected to the inner wall of the protective cover 4. The top end of the worm gear 502 is fixedly connected to a universal joint 503. The other end of the universal joint 503 extends through the inner wall of the protective cover 4 to the outside and is fixedly connected to an adjusting wheel 504. The adjusting wheel 504 drives the connected universal joint 503 to rotate, which in turn drives the connected worm gear 502 to rotate. The worm gear 502 drives the baffle 5 connected to the worm gear 501 to rotate and open.
[0025] By providing the protective cover 4 and the baffle 5, when the condenser microphone 8 is not in use, it can be retracted into the protective cover 4 and the baffle 5 can be driven to close, thereby protecting the condenser microphone 8 and ensuring that the condenser microphone 8 will not be exposed to moisture and adverse environments, thereby improving the service life of the condenser microphone 8.
[0026] like Figure 6 As shown, one end of the movable ring 6 is fixedly connected to an electric push rod 601, and the other end of the electric push rod 601 is fixedly connected to the inner wall of the protective cover 4. One side of the movable ring 6 is symmetrically fixedly connected to two transmission racks 602, which are meshed with the adjustment wheel 504 for transmission. When the electric push rod 601 drives the movable ring 6 to move downward, the transmission rack 602 on the movable ring 6 drives the adjustment wheel 504 to rotate.
[0027] A motor 603 is fixedly mounted on the movable ring 6. A transmission wheel 604 is fixedly mounted on the output end of the motor 603. A concave-convex annular groove 605 is fixedly mounted on the inner wall of the movable ring 6. The motor 603 drives the transmission wheel 604 to rotate, which in turn drives the rotating ring 7 connected to the annular rack B701. This in turn drives the condenser microphone 8 mounted on the swinging ring 801 to rotate.
[0028] like Figure 7As shown, an annular rack B701 is fixedly connected to the rotating ring 7, which meshes with the transmission wheel 604 for transmission. A slider 702 is fixedly connected to one side of the rotating ring 7. A movable rod 703 is slidably mounted on the outer wall of the slider 702. A sliding head 704 is fixedly connected to the bottom end of the movable rod 703. The outer wall of the sliding head 704 slidably engages with the inner wall of the concave-convex annular groove 605. An adjustment rack 705 is fixedly connected to the movable rod 703. When the rotating ring 7 rotates, the sliding head 704 slides within the concave-convex annular groove 605, thereby driving the movable rod 703 connected to the sliding head 704 to move up and down. This causes the adjustment rack 705 on the movable rod 703 to drive the swing ring 801 connected to the gear 802 to swing back and forth, causing the condenser microphone 8 to swing back and forth.
[0029] like Figure 8 As shown, a swing ring 801 is fixedly connected to the condenser microphone 8, and the swing ring 801 is rotatably connected to the rotating ring 7. A gear 802 is fixedly connected to one end of the swing ring 801, and the gear 802 is meshed with the adjustment rack 705 for transmission. A conical cover 804 is fixedly connected to the bottom end of the condenser microphone 8, and a plurality of sound receiving micro-holes 803 are opened on the lower end surface of the condenser microphone 8. The diameter of the sound receiving micro-holes 803 is 0.001mm-0.014mm, and the distance between any two adjacent sound receiving micro-holes 803 is 0.01mm-0.1mm.
[0030] The conical cover 804 can effectively reduce interference from wind or airflow. When wind blows through the condenser microphone 8, it will generate noise. Especially when used outdoors, the conical cover 804 can reduce the direct impact of wind on the condenser microphone 8 and reduce wind noise. The structural design of the conical cover 804 can help isolate unnecessary noise in the surrounding environment, such as background noise and noise, so that the condenser microphone 8 can focus more on receiving sound from a specific direction, thereby improving audio clarity. The design of the conical cover 804 can further enhance the waterproof performance of the condenser microphone 8, especially for the microporous waterproof condenser microphone 8. Under the protection of the conical cover 804, the conical cover 804 can effectively prevent sweat, rain and other liquids from directly contacting the surface of the condenser microphone 8, reducing the potential impact of liquids on the performance and circuit of the condenser microphone 8, and helping to maintain its waterproof effect. The conical cover 804 not only protects the condenser microphone 8 and ensures its efficient operation, but also provides better audio effects and reliability in complex environments.
[0031] By opening a number of sound receiving micro-holes 803 on the sound receiving surface of the condenser microphone 8, the surface tension of the liquid can be used to fix the liquid in the number of sound receiving micro-holes 803, preventing external liquid from entering the interior of the condenser microphone 8, which can effectively play a waterproof role, achieve a more ideal sound receiving effect, avoid distortion, and avoid a decrease in the high-frequency frequency curve.
[0032] Working Principle: When the condenser microphone 8 is to be used at night, it is mounted on the headlamp 3. First, the mounting ring 1 is placed on the headlamp 3. Then, the lever 103 is used to rotate the adjusting ring 101. This causes the adjusting ring 101 to drive the connected annular rack A102. This in turn causes the annular rack A102 to rotate the driving wheel 203. This in turn causes the driving wheel 203 to rotate the threaded sleeve 202. This causes the threaded sleeve 202 to move the threaded rod 206, which in turn drives the mounting rod 205 to rest against the headlamp 3 for fixation. Then, when the electric push rod 601 drives the movable ring 6 to move downward, the transmission rack 602 on the movable ring 6 drives the adjusting wheel 504 to rotate, so that the adjusting wheel 504 drives the connected universal joint 503 to rotate, and the universal joint 503 drives the connected worm 502 to rotate, so that the worm 502 drives the baffle 5 connected to the worm wheel 501 to rotate and open, so that the condenser microphone 8 can be removed from the protective cover 4 for use; After the condenser microphone 8 is used up, when it is put back into the protective cover 4, the motor 603 is used to drive the transmission wheel 604 to rotate, so that the transmission wheel 604 drives the rotating ring 7 connected to the annular rack B701 to rotate. At this time, the rotating ring 7 drives the condenser microphone 8 on the swinging ring 801 to rotate. At the same time, when the rotating ring 7 rotates, the sliding head 704 slides in the concave-convex ring groove 605, thereby driving the movable rod 703 connected to the sliding head 704 to move up and down, so that the adjustment rack 705 on the movable rod 703 drives the swinging ring 801 connected to the gear 802 to swing back and forth, so that the condenser microphone 8 swings back and forth. The self-rotation swing can help the condenser microphone 8 removes accumulated water and water vapor from the surface of the sound receiving microholes 803, preventing water droplets from condensing or accumulating for a long time inside the condenser microphone 8, thereby maintaining the waterproof function. The rotating shaking can effectively remove dust, fine particles or other impurities on the surface, keep the surface of the condenser microphone 8 clean, avoid the sound receiving microholes 803 from being blocked, and ensure the clarity and stability of the sound. The shaking drainage action can reduce the long-term accumulation of moisture on the internal components of the condenser microphone 8, reduce the probability of circuit corrosion or short circuit caused by moisture, and enhance the stability of the equipment. By shaking to quickly remove moisture, the workload of subsequent cleaning and maintenance can be reduced, which is convenient for the next use of the condenser microphone 8 and improves the efficiency of equipment use.
