Background

A Microphone (also called a Microphone or a Microphone, formal name of chinese is a Microphone) is a transducer for converting sound into an electrical signal, which is encoded by english Microphone. The microphone is characterized in that sound vibration is transmitted to a diaphragm of the microphone to push a magnet inside the microphone to form a variable current, and the variable current is transmitted to a following sound processing circuit for amplification processing. Sound is a wonderful thing. The different sounds we hear are all produced by the slight pressure difference of the air around us. The wonderful point is that the air is able to transmit these pressure differences so well and so realistically over considerable distances. It is connected by a metal membrane to a needle which scrapes the pattern on a piece of metal foil. When you speak into the membrane, the resulting air pressure differential moves the membrane and thus the needle, which movement is recorded on the foil. Subsequently, when you run the needle back on the foil, the vibrations generated by the scraping on the foil will move the membrane, reproducing the sound.
