MOBILE HAPTIC ACTUATOR

摘要

According to an embodiment of the present invention, provided is a mobile haptic actuator, comprising: a body having an inner space; a vibration panel provided in the inner space of the body and configured to vibrate due to repeated bending; a piezoelectric device configured to expand or contract depending on voltage application, and coupled to a terminal part of the vibration panel; and a pressing unit coupled to the body to apply pressure to the vibration panel. The present invention provides a mobile haptic actuator capable of maintaining driving power and resonant frequency performance and reducing the size thereof.
