Positioning of Actuators within Tactile Functions

Various actuators are used for tactile functions. "Notification" uses eccentricity motors, linear resonance actuators, and other electromagnetic actuators, while "force feedback" utilizes piezoelectric actuators in addition to such electromagnetic actuators. The subsequent "tactile sensation" requires piezoelectric actuators with a broad drive frequency band and a quick response speed.
