MODULE FOR PROVIDING HAPTIC FEEDBACK, DEVICE FOR PROVIDING HAPTIC EMOTIONAL FEEDBACK USING SAME, PORTABLE TERMINAL HAVING SAME, DEVICE FOR INDICATING DIRECTION HAVING SAME, AND METHOD FOR PROVIDING HAPTIC EMOTIONAL FEEDBACK HAVING SAME

摘要

The present invention relates to a module for providing haptic feedback, a device for providing haptic feedback by means of the module for providing haptic feedback, a portable terminal having the device for providing haptic feedback, and a method for providing haptic feedback by means of the module for providing haptic feedback. More specifically, the module for providing haptic feedback comprises: a housing; a vibration plate provided in the interior of the housing; an actuating unit, provided in between the housing and the vibration plate, for moving the vibration plate back and forth; and a plurality of vibration units, provided in between the vibration plate and the housing, each having a different resonant frequency. Thus, by changing the oscillation frequency of the actuating unit, a vibration unit having a resonant frequency coincident to the oscillation frequency is induced to vibrate at the resonance frequency thereof.
