Electrostatic principles

Electrostatic principles are a form of [transduction] that [condenser mics] use to convert [acoustic energy] to [electrical energy].

  1. Power supply provides static charge between plates
  2. Movable front plate vibrates in response to sound waves
  3. As plates move closer together, capacitance increases, and voltage decreases (and vice-versa)
