Electrostatic loudspeakers work by the attraction and repulsion of a thin conductive film in an electric field rather than the magnetic attraction and repulsion you’ll find in a moving-coil ...

An electrostatic loudspeaker uses a thin plastic diaphragm residing between two perforated metal sheets (the grids or stator plates). The audio signal is applied to the grids out of phase.

Normally electrostatic sparks are very small. If the object has a lot of charge, then these sparks can be hundreds of metres long. Sparks can occur between charged objects and people. Sometimes ...
