electrostatic transducer

[i′lek·trə‚stad·ik tranz′dü·sər]
(engineering acoustics)
A transducer consisting of a fixed electrode and a movable electrode, charged electrostatically in opposite polarity; motion of the movable electrode changes the capacitance between the electrodes and thereby makes the applied voltage change in proportion to the amplitude of the electrode's motion. Also known as condenser transducer.
