Abstract
Provided is a thin film type actuator having multi-operation points, capable of various feels of touch or sounds. The film type actuator includes an upper plate and a lower plate, formed of a single plate. Between the upper plate and the lower plate, pairs of electrode parts capable of attracting one another via an electrostatic force. Since each of the pairs of electrode parts functions as an operation point and the upper plate and the lower plate are formed of the single plate, movements of the respective operation points in such a way that a new physical movement different from an original individual movement is generated to generate a haptic feel or a sound. It is possible to generate various haptic feels or sounds by modulating and combining amplitudes and frequencies of the respective operation points.
