Condenser Microphones

Condenser Microphones. Condenser microphones, also called electrostatic or capacitor microphones, convert sound into electricity using electro static principals. They have two plate elements, one moveable and one fixed.

  1. CondenserMicrophones

  2. Condenser microphones, also called electrostatic or capacitor microphones, convert sound into electricity using electrostatic principals. They have two plate elements, one moveable and one fixed. The moveable plate is given an electrical charge from a power source, creating electrostatic energy between the plates. Condenser Operation

  3. Cross-Section of a Typical Condenser Microphone • They have two plate elements, one moveable and one fixed. • The moveable plate is given an electrical charge from a power source, creating electrostatic energy between the plates.

  4. Sound waves vibrate the movable plate. As the distance between the two plates changes, the amount of stored electricity changes. Operation Continued

  5. Condenser mics are very sensitive, and can respond quickly and accurately to sound. Condenser mics are sensitive

  6. The signal out of the capacitor is small and must be pre-amplified or boosted. Since capacitors require a charge, condenser microphones require a power source from a battery or phantom power. Inside a Condenser Microphone These Microphones need power

  7. They are used in situations where they are not subjected to much sound pressure. Not too much sound pressure Sound pressure level history

  8. Because condenser mics can handle high frequencies well, they are used in musical applications – in the string section of an orchestra for example. Condenser mics
