Description of an electrostatic transducer
The electrostatic transduction is usually done with a variable capacitor.
In its most simple form, this capacitor is made up of two plane electrodes. One of these electrodes is mobile and can move towards or away from the fixed electrode.
Exemple : Example
 | This photo represents two electrostatic microphone capsules. Here, the membrane acts as the mobile electrode of the transducer (visible on the left capsule). The perforated rear electrode is visible on the right capsule due to the removal of the membrane. This electrode is the transducers immobile electrode |
