Working Principle of a Condenser Microphone - The varying sound pressure changes the spacing between a thin metallic membrane and a stationary plate, producing electrical signals which “copy” the sound pressure. Salient Features: Works with a wide range of sound frequencies. Although expensive, it is considered as the best microphone for recording applications. Working Principle of a Dynamic Microphone - The varying sound pressure moves the cone diaphragm and the coil attached to it within a magnetic field, producing an electromotive force that generates electrical signals which “copy” the sound pressure. Salient Features: The inverse of a dynamic loudspeaker and relatively cheap and rugged.
