Condenser microphone and Dynamic microphone

1. Transform sound into electric signal- The best design in theory:The design of electret condenser microphones is based on the theorem that we use charging and discharging motionbetween electric capacity conductors. When the ultra-thin or gold-plating Mylar diaphragm response to the soundpressure level, it changes the static electricity between the conductors into electric signal directly. Then we can gaina proper output of impedance and sensitivity by the electric circuit coupling.
2. The characteristic of reappearing the original sound:To reappear the original sound is the highest performance for the acoustic specialist to achieve. If we check the basicdesign of the microphone, we can find a electret condenser microphone can transform the sound into electric signaldirectly, because it is not only manufactured with accurate mechanism technique, but also combine complicated electriccircuit. Therefore, with the excellent characteristic in advance, the electret condenser microphone must be your best choice.
3. Very wild frequency response:Diaphragm is a main component of a microphone to sense the sound and to transform it into the electric signal.The material and the mechanical design of the diaphragm decide the acoustics of a microphone. Due to the materialof the diaphragm is very thin and light, and can transform the sound into electric signal directly; the range of thefrequency response can reach to the ultra-low frequency (under 10 Hz), and the high frequency can also gets tosupersonic easily, which shows the characteristic of wild frequency response.
The diaphragm of the dynamic microphone loads a sound coil which is hundreds times heavier than itself. (Left picture)The diaphragm of the electret condenser microphone works without any load. (Right picture)
