What are the main components of a condenser microphone?
Condenser microphones use a pair of charged metal plates, one fixed (the backplate) and one movable (the diaphragm), forming a capacitor. When a sound wave hits the diaphragm, the distance between the two plates changes which produces a change in an electrical characteristic called capacitance.
How are condenser microphones constructed?
The electrostatic or condenser microphone is constructed with the diaphragm as one plate of a parallel-plate capacitor. The most popular form of this type of microphone is the electret condenser microphone, in which the plates are given a permanent electrical charge.
What is the structure of a microphone?
The microphone commonly consists of a magnetic (moving coil) transducer, contact plate and contact pin. The contact plate is placed directly on the vibrating part of a musical instrument or other surface, and the contact pin transfers vibrations to the coil.
What pattern is a condenser mic?
The most common microphone polar pattern, and the one used by every PreSonus condenser microphone is called “cardioid.” The word “cardioid” is derived from the Greek word for “heart.” A cardioid polar pattern means the microphone primarily picks up sound within an area that is roughly heart-shaped when shown on a two- ...
