Haptic feedback device for portable terminal

The present invention, the input member is provided on the terminal; A vibration member installed to penetrate the input member to provide a rotation axis of the input member; And a piezo actuator connected to the vibration member, wherein the piezoelectric element is driven to vibrate the vibration member as the input member rotates or rotates about the rotation axis. do. The haptic device of the portable terminal configured as described above may implement a haptic feedback function in combination with a haptic feedback function provided on the touch screen even when an input member installed separately from the touch screen is provided, and the user watches the screen when operating the corresponding input member. Even if you do not want to know that the desired operation is made, there is an advantage that it is convenient to use. Handset, haptic, piezoelectric element, jog dial, wheel key
