Definition of Electret. Meaning of Electret. Synonyms of Electret

- An electret (formed as a portmanteau of electr- from "electricity" and -et from "magnet") is a dielectric material that has a quasi-permanent electrical...
- electret microphone is a microphone whose diaphragm forms a capacitor (historically-termed a condenser) that incorporates an electret. The electret's...
- to electrostatic drivers, electret drivers are permanently charged eliminating the need for an external amplifier. Electret drivers are commonly used...
