What is Electrostatic loudspeaker?
[[File:ESL_voorbeeld.png|thumb|Electrostatic speaker]] An '''electrostatic loudspeaker''' is a design of [[loudspeaker|speaker]]. The sound is generated by [[Force (physics)|force]] placed on a [[membrane]] suspended in an [[electrostatic field]]. The electrostatic loudspeaker is almost like [[magnetostatic loudspeaker]] but it does not use high [[Electric current|current]]s, it uses high [[voltage]]s. The membrane (a thin film) is controlled by voltage, and it moves between metal plates which are full of small holes. The sound quality from modern models of electrostatic loudspeaker is good. {{tech-stub}} [[Category:Audio technology]]
