Generates an electrical signal from the microphone moving magnetic field conductor. Is driven by a coil vibrating diaphragm microphone cable, so that the coil in a magnetic field induced current is generated. Features: recording microphone solid structure, stable performance, durable, low price; the frequency characteristics of a good, within the frequency range 50-15000Hz flat amplitude-frequency characteristic curve; good point; no DC voltage, easy to use, low noise. Generally divided into heart-shaped, super heart-shaped, eight-shaped, gun, omni-directional and so on. See Figure 02 microphone pointing schematic As these points to how it was, you can try to find a microphone. As shown, the arrow in front of the microphone are corrected, the dotted line is the approximate range can pickup and microphone stand outside this range, the pickup will be insensitive. If the conditional microphone, recommendations or find a more pointed the microphone to try, we can understand the significance of the point. The microphone is the sound vibrations transmitted by the microphone diaphragm, to promote the change of the current inside the magnets, so that the back of the varying current supplied to the voice processing circuit enlargement processing. The sound is wonderful stuff. We hear various sounds around us are made up of tiny air pressure generated. Wonderful place that they can air pressure so well, so true for quite a long distance transmission. It is connected by a metal diaphragm to the needle, which needle scratch pattern on a piece of metal foil. When you speak towards the diaphragm, the air pressure generated by movement of the diaphragm, so that the movement of the needle, the needle movement is recorded on the metal foil. Then, when you run the needle on the metal foil to the back, on a metal foil scratch vibrations cause movement of the diaphragm, the sound reproduction. This purely mechanical system running shows can produce vibrations in the air how much energy! Microphone stand, microphone, video provided by Wuhan Wuhan Jiuhua Jiuhua Video Engineering Limited.
