  1. Extremely thin strip of corrugated metal suspended between the poles of a magnet.
    The air pressure of the sound waves vibrates the ribbon and induces an electronic current
    The voltage mimics the frequency and intensity of the sound source.
    Used for recording and sometimes in the orchestra pit.
    ribbon microphone
  2. The heart contains a magnet surrounded by a wire coil.
    One end of the coil is attached to the microphone’s diaphragm.
    When sound waves strike the diagram it vibrates which vibrates the coil.
    An induced current is generated that mimics the frequency and intensity of the sound wave
    Uses: onstage use and recording
    dynamic microphone
  3. Diaphragm of thin conductive materials forms one half of a capacitor.
    When
    sound waves strike the diaphragm the pressure changes the space between
    the two plates. This causes a change in the capacitance of the
    condenser.
    The movement changes the voltage in the plates.
    The voltage change mimics the frequency and intensity generated by the source.Requires a power supply
    condensor microphone
