Description

Technical Field

[0001] This invention relates to the field of condenser microphone technology, and more particularly to a micro-perforated waterproof condenser microphone. Background Technology

[0002] A condenser microphone, also known as a condenser microphone or electret microphone, is a device that converts sound signals into electrical signals by changing the capacitance. Due to their superior performance, condenser microphones are widely used in various settings, including recording studios, professional performances, conference hosting, live streaming, and game voice communication. Whether for high-quality professional recording or everyday live streaming and game voice communication, condenser microphones provide a clear, detailed, and accurate audio experience.

[0003] The prior art publication CN105451143B discloses a windproof micro-perforated waterproof electret condenser microphone. This technology can be applied to the sound pickup parts of waterproof and windproof electronic products as well as portable outdoor sports equipment. Its advantages include being breathable but not waterproof, employing a waterproof airtight cavity structure, so sound does not need to pass through a traditional waterproof membrane, resulting in good performance in waterproof conditions, and good microphone sensitivity and full-frequency sound pickup. Moreover, in normal environments, the waterproof airtight cavity is unobstructed, and due to the absence of a waterproof membrane, the sound pickup effect is more ideal, while also providing windproof performance, making its application more versatile and convenient.

[0004] Condenser microphones are sensitive to humid environments. In existing technology, when used outdoors, such as mounted on a hiking headlamp, condenser microphones lack protection and are easily affected by water droplets and other external environmental factors when exposed to humid air. Without effective protective design and proper storage when not in use, the sensitive components of the microphone may be damaged due to exposure.

[0005] In summary, existing technologies lack protection for condenser microphones. Summary of the Invention

[0008] Preferably, an adjusting ring is rotatably connected to the mounting ring, an annular rack A is fixedly connected to the adjusting ring, and a lever is fixedly connected to the adjusting ring.

[0009] Preferably, the mounting mechanism includes a fixed base, which is fixedly connected to the mounting ring. A threaded sleeve is rotatably connected through the fixed base, and a drive wheel is fixedly connected to the outer wall of the threaded sleeve. The drive wheel is engaged with a ring rack A for transmission.

[0010] Preferably, a guide rod is slidably fitted through the fixed base, and an installation rod is fixedly connected to the bottom end of the guide rod. The installation rod abuts against the outer wall of the headlamp, and a threaded rod is fixedly connected to the installation rod. The threaded rod is threadedly connected to a threaded sleeve.

[0011] Preferably, a worm gear is fixedly connected to one end of the baffle, a worm is engaged with one side of the worm gear, the bottom end of the worm is rotatably connected to the inner wall of the protective cover, a universal joint is fixedly connected to the top end of the worm, and the other end of the universal joint extends through the inner wall of the protective cover to the outside and is fixedly connected to an adjusting wheel.

[0012] Preferably, one end of the moving ring is fixedly connected to an electric push rod, the other end of the electric push rod is fixedly connected to the inner wall of the protective cover, and two transmission racks are fixedly connected to one side of the moving ring in a symmetrical structure, the transmission racks meshing with the adjusting wheel for transmission.

[0013] Preferably, a motor is fixedly connected to the moving ring, a transmission wheel is fixedly connected to the output end of the motor, and a concave-convex ring groove is fixedly connected to the inner wall of the moving ring.

[0014] Preferably, an annular rack B is fixedly connected to the rotating ring, and the annular rack B is meshed with the transmission wheel for transmission. A slider is fixedly connected to one side of the rotating ring, and a movable rod is slidably fitted on the outer wall of the slider. A sliding head is fixedly connected to the bottom end of the movable rod, and the outer wall of the sliding head is slidably fitted with the inner wall of the concave-convex ring groove. An adjusting rack is fixedly connected to the movable rod.

[0015] Preferably, a swing ring is fixedly connected to the condenser microphone, the swing ring is rotatably connected to the rotating ring, a gear is fixedly connected to one end of the swing ring, the gear meshes with the adjusting rack, a conical cover is fixedly connected to the bottom of the condenser microphone, and a plurality of sound-receiving micro-holes are opened on the lower end surface of the condenser microphone, the diameter of the sound-receiving micro-holes is 0.001mm-0.014mm, and the distance between any two adjacent sound-receiving micro-holes is 0.01mm-0.1mm.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting up a protective cover and baffle, when the condenser microphone is not in use, it can be retracted into the protective cover and the baffle can be closed at the same time, thus protecting the condenser microphone and ensuring that it is not exposed to humid and adverse environments, thereby improving the service life of the condenser microphone; at the same time, by opening several micro-holes on the sound-receiving surface of the condenser microphone, the liquid can be fixed in several micro-holes by utilizing the surface tension of the liquid, preventing external liquid from entering the condenser microphone, effectively playing a waterproof role, making the sound reception effect more ideal, avoiding distortion, and avoiding the drop of the high frequency curve;

[0018] 2. By setting up a moving ring, a rotating ring, and a swinging ring, the condenser microphone can be rotated and oscillated back and forth while being retracted after use. This effectively cleans the surface of the condenser microphone, removes moisture and water vapor, reduces water accumulation, maintains waterproof performance, and helps extend the life of the microphone. It also makes the microphone sound clearer, reduces the risk of internal components being corroded by moisture, and improves the stability and reliability of the equipment.

[0019] 3. By setting up an installation mechanism, after the mounting ring is put on the headlamp, multiple mounting rods are used to fix the condenser microphone on the headlamp for use. This avoids the situation where existing condenser microphones are not suitable for headlamp installation due to the clamping and fixing method, effectively improving the stability of the microphone and preventing it from falling off.

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-8 The micro-hole waterproof condenser microphone shown includes a mounting ring 1, on which multiple mounting mechanisms 2 are fixedly connected. A headlamp 3 is fitted inside the mounting ring 1. A protective cover 4 is fixedly connected to one side of the mounting ring 1. Two baffles 5 are rotatably connected at the bottom opening of the protective cover 4 in a symmetrical structure. A movable ring 6 is set inside the protective cover 4. A rotating ring 7 is rotatably connected to the movable ring 6. A condenser microphone 8 is rotatably connected to the rotating ring 7.

[0031] like Figure 3 As shown, an adjusting ring 101 is rotatably connected to the mounting ring 1, and an annular rack A102 is fixedly connected to the adjusting ring 101. A lever 103 is also fixedly connected to the adjusting ring 101. By lever 103, the adjusting ring 101 is rotated, causing the adjusting ring 101 to drive the connected annular rack A102, which in turn drives the drive wheel 203 to rotate.

[0032] like Figure 4As shown, the mounting mechanism 2 includes a fixed base 201, which is fixedly connected to the mounting ring 1. A threaded sleeve 202 is rotatably connected through the fixed base 201. A drive wheel 203 is fixedly connected to the outer wall of the threaded sleeve 202. The drive wheel 203 is meshed with the annular rack A102 for transmission.

[0033] A guide rod 204 is slidably mounted on the fixed base 201. A mounting rod 205 is fixedly connected to the bottom end of the guide rod 204. The mounting rod 205 abuts against the outer wall of the headlamp 3. A threaded rod 206 is fixedly connected to the mounting rod 205, and the threaded rod 206 is threadedly connected to a threaded sleeve 202. This causes the drive wheel 203 to rotate the threaded sleeve 202, which in turn causes the threaded sleeve 202 to move the threaded rod 206, thus causing the mounting rod 205 to abut against the headlamp 3 for fixation.

[0034] like Figure 5 As shown, a worm gear 501 is fixedly connected to one end of the baffle 5. A worm 502 is meshed and driven on one side of the worm gear 501. The bottom end of the worm 502 is rotatably connected to the inner wall of the protective cover 4. A universal joint 503 is fixedly connected to the top end of the worm 502. 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 502 to rotate, causing the worm 502 to drive the baffle 5 connected to the worm gear 501 to rotate and open.

[0035] By setting up a protective cover 4 and a 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 closed at the same time, thereby protecting the condenser microphone 8 and ensuring that the condenser microphone 8 is not exposed to humid and adverse environments, thus improving the service life of the condenser microphone 8.

[0036] like Figure 6 As shown, an electric actuator 601 is fixedly connected to one end of the moving ring 6, and the other end of the electric actuator 601 is fixedly connected to the inner wall of the protective cover 4. Two transmission racks 602 are fixedly connected to one side of the moving ring 6 in a symmetrical structure, and the transmission racks 602 mesh with the adjusting wheel 504 for transmission. When the electric actuator 601 drives the moving ring 6 to move downward, the transmission racks 602 on the moving ring 6 will drive the adjusting wheel 504 to rotate.

[0037] A motor 603 is fixedly connected to the moving ring 6, and a transmission wheel 604 is fixedly connected to the output end of the motor 603. A concave-convex annular groove 605 is fixedly connected to the inner wall of the moving 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 to rotate. At this time, the rotating ring 7 drives the condenser microphone 8 on the swing ring 801 to rotate.

[0038] like Figure 7 As shown, a ring rack B701 is fixedly connected to the rotating ring 7. The ring rack B701 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 fitted 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 is slidably fitted with the inner wall of the concave-convex ring groove 605. An adjusting rack 705 is fixedly connected to the movable rod 703. 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. This causes the adjusting 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.

[0039] like Figure 8 As shown, a swing ring 801 is fixedly connected to the condenser microphone 8. 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. The gear 802 meshes with the adjusting rack 705 for transmission. A conical cover 804 is fixedly connected to the bottom of the condenser microphone 8. Several 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.

[0040] The cone-shaped cover 804 effectively reduces interference from wind or airflow. Wind blowing across the condenser microphone 8 generates noise, especially during outdoor use. The cone-shaped cover 804 reduces the direct impact of wind on the condenser microphone 8, minimizing wind noise. The cone-shaped cover 804's structural design helps isolate unwanted ambient noise such as background noise, allowing the condenser microphone 8 to focus more on receiving sound from a specific direction, thus improving audio clarity. The cone-shaped cover 804 further enhances the waterproof performance of the condenser microphone 8, especially for microporous waterproof condenser microphones. Under the protection of the cone-shaped cover 804, sweat, rain, and other liquids can effectively prevent direct contact with the surface of the condenser microphone 8, reducing the potential impact of liquids on the performance and circuitry of the condenser microphone 8, helping to maintain its waterproof effect. The cone-shaped cover 804 not only protects the condenser microphone 8, ensuring its efficient operation, but also provides better audio performance and reliability in complex environments.

[0041] By opening several micro-holes 803 on the sound-receiving surface of the condenser microphone 8, the liquid can be fixed inside the micro-holes 803 by utilizing the surface tension of the liquid, preventing external liquid from entering the condenser microphone 8. This effectively provides waterproofing, resulting in a more ideal sound reception effect, avoiding distortion, and preventing the high-frequency curve from dropping.

[0042] Working principle: When the condenser microphone 8 needs to be used at night, it is installed on the headlamp 3. First, the mounting ring 1 is put on the headlamp 3. Then, the adjusting ring 101 is rotated by the lever 103, which drives the connected annular rack A102. The annular rack A102 drives the drive wheel 203 to rotate, which drives the threaded sleeve 202 to rotate. The threaded sleeve 202 drives the threaded rod 206 to move, which drives the mounting rod 205 to abut against the headlamp 3 for fixation.

[0043] Then, when the electric push rod 601 drives the moving ring 6 to move down, the transmission rack 602 on the moving ring 6 will drive the adjusting wheel 504 to rotate, which in turn drives the universal joint 503 to rotate, which in turn drives the worm gear 502 to rotate, which in turn drives the baffle 5 connected to the worm wheel 501 to rotate and open, so that the condenser microphone 8 can be moved out of the protective cover 4 for use.

[0044] After the condenser microphone 8 is used and returned to the protective cover 4, the motor 603 drives the transmission wheel 604 to rotate, which in turn drives the rotating ring 7 connected to the annular rack B701 to rotate. At this time, the rotating ring 7 causes the condenser microphone 8 on the swing ring 801 to rotate. Simultaneously, as the rotating ring 7 rotates, the sliding head 704 slides within the concave-convex groove 605, causing the movable rod 703 connected to the sliding head 704 to move up and down. This causes the adjusting rack 705 on the movable rod 703 to drive the swing ring 801 connected to the gear 802 to reciprocate, resulting in the condenser microphone 8 reciprocating. This rotation and swinging motion helps the condenser microphone... The microphone 803, which is a microphone hole, removes water and moisture from its surface, preventing water droplets from condensing or accumulating inside the microphone 8 and maintaining its waterproof function. The rotating and shaking motion effectively removes dust, fine particles, or other impurities from the surface, keeping the microphone 8 clean and preventing the microphone hole 803 from becoming blocked. This ensures sound clarity and stability. The shaking action also reduces the long-term accumulation of moisture on the internal components of the microphone 8, lowering the probability of circuit corrosion or short circuits caused by moisture, and enhancing the stability of the device. Furthermore, the rapid removal of moisture through shaking reduces the workload of subsequent cleaning and maintenance, facilitating the next use of the microphone 8 and improving the efficiency of the device.
