Description

Technical Field

[0001] This utility model relates to the field of silicon microphone technology, and in particular to a high-sensitivity silicon microphone. Background Technology

[0002] High-sensitivity silicon microphones primarily involve microelectromechanical systems (MEMS) and integrated circuit (IC) manufacturing technologies. MEMS microphones, also known as silicon microphones or silicon microphones, are manufactured using silicon etching and fabrication techniques originally developed for integrated circuits. Since the 1990s, MEMS technology has created various sensors and other electromechanical devices, including microphones. These microphones operate by using application-specific integrated circuits (ASICs) to amplify, convert analog-to-digital signals, and filter weak electrical signals. The frequency response curve, as described in the datasheet, illustrates the characteristic of a microphone's sensitivity changing with frequency. This is called the microphone's frequency response characteristic, also known as its frequency response curve. When a microphone receives sound of different frequencies, the amplitude of the output signal will increase or decrease with the change in frequency. Unless otherwise specified, microphones with a flat frequency response should be selected whenever possible.

[0003] High-sensitivity silicon microphones are mostly used for voice-over work, recording environmental and natural sounds, long-distance "shotgun" recording, and recording acoustic guitars and other instruments. Due to their high sensitivity, silicon microphones are relatively delicate and easily damaged. Most existing high-sensitivity silicon microphones are fixedly installed inside the recording microphone, making them inconvenient to repair or replace. Therefore, we propose a high-sensitivity silicon microphone to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a high-sensitivity silicon microphone to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-sensitivity silicon microphone includes: a microphone base and a microphone body, the microphone base and the microphone body being electrically connected; a fixed ring is fixedly installed on the outer side of the microphone base; a mounting ring is movably abutted against the top of the fixed ring; a microphone frame is fixedly connected to the top of the mounting ring; multiple insertion blocks are integrally formed at the bottom of the mounting ring; a limiting ring is fixedly installed inside the fixed ring; multiple fixing springs are fixedly installed inside the limiting ring; a limiting wedge is fixedly installed on one side of each fixing spring; the bottom of the limiting wedge movably abuts against the top of the insertion block; a fixed rod is fixedly installed at the bottom of the limiting wedge; a toggle ring is rotatably installed inside the fixed ring; the fixed rod is slidably connected to the toggle ring; a toggle plate is integrally formed on the toggle ring; the toggle plate is slidably connected to the fixed ring; and an adjustment component is provided on the outer side of the fixed ring.

[0007] Preferably, the adjustment component includes: a rotating bracket and a rotating block, the rotating block being rotatably mounted on one side of the rotating bracket, a small helical rod being fixedly mounted on one side of the rotating block, a pressing block being threaded onto the small helical rod, and two rotating blocks integrally formed on the fixed ring, both rotating blocks being rotatably connected to the rotating bracket, and the pressing block being movably abutting against one of the rotating blocks.

[0008] Preferably, the limiting ring has multiple limiting square grooves, the fixing spring is fixedly installed in the limiting square grooves, the limiting inclined block is slidably installed in the limiting square grooves, the bottom end of the limiting square grooves has a sliding hole that matches the fixing round rod, and the actuating ring has multiple sliding square grooves that match the limiting rings.

[0009] Preferably, a circular protrusion is fixedly installed at the bottom of the rotating bracket, a rotating disk is fixedly installed at the bottom of the circular protrusion, a connecting cylinder is rotatably installed on the outer side of the rotating disk, and a rotating groove matching the rotating disk is opened on the connecting cylinder.

[0010] Preferably, a rotating block is rotatably mounted on one side of the connecting cylinder, and a large spiral rod is fixedly mounted on one side of the rotating block. A movable arc plate is threaded onto the large spiral rod, and the movable arc plate movably abuts against one side of the rotating disk.

[0011] Preferably, the limiting ring has an insertion square groove that matches the insertion stop block, the fixing ring has a toggle sliding groove that matches the toggle square plate, and the connecting cylinder has a moving groove that matches the moving arc plate.

[0012] In this invention, a high-sensitivity silicon microphone is described. By pushing a toggle plate, the toggle plate moves its toggle ring. When the toggle ring moves, it moves the fixed rod that is slidably connected to it. The fixed rod moves the limiting wedge block, which compresses the fixed spring and retracts into the limiting groove on the limiting ring, thereby releasing the restriction on the plug-in block. Then, the microphone frame is lifted, and the mounting ring fixedly installed on the microphone frame moves, allowing the plug-in block to exit from the plug-in groove, facilitating the maintenance and replacement of the microphone body.

[0013] In this invention, a high-sensitivity silicon microphone is described. By rotating a rotating block, the rotating block drives a small spiral rod to rotate, thereby controlling the movement of a pressing block. This pressing block presses against or separates from a fixed ring, thereby adjusting the angle of the fixed ring. Finally, by rotating the rotating block, it drives a large spiral rod to rotate, thereby controlling the movement of a moving arc plate, which presses against a rotating disk, thus adjusting the rotation angle between the circular protrusion and the rotating bracket.

[0014] This utility model has a reasonable structural design. By moving the square plate, the moving ring causes the fixed round rod to move the limiting inclined block, which makes disassembly more convenient and quick, and facilitates the maintenance and replacement of the silicon microphone fixed in the microphone.

[0023] In this embodiment, the adjustment component includes: a rotating bracket 5 and a rotating block 6. The rotating block 6 is rotatably mounted on one side of the rotating bracket 5. A small spiral rod 21 is fixedly mounted on one side of the rotating block 6. A pressing block 15 is threaded onto the small spiral rod 21. Two rotating blocks are integrally formed on the fixed ring 2. Both rotating blocks are rotatably connected to the rotating bracket 5. The pressing block 15 moves and abuts against one of the rotating blocks to better receive sound.

[0024] In this embodiment, the limiting ring 11 has multiple limiting square grooves, the fixing spring 17 is fixedly installed in the limiting square groove, the limiting inclined block 18 is slidably installed in the limiting square groove, the bottom end of the limiting square groove has a sliding hole that matches the fixing round rod 19, the moving ring 12 has multiple sliding square grooves that match the limiting ring 11, making it easier to slide, the bottom end of the rotating bracket 5 is fixedly installed with a circular protrusion 20, the bottom end of the circular protrusion 20 is fixedly installed with a rotating disk 9, the outside of the rotating disk 9 is rotatably installed with a connecting cylinder 7, the connecting cylinder 7 has a rotating groove that matches the rotating disk 9, making it easier to rotate.
