Haptic feedback device and electronic device

Abstract

Disclosed are a haptic feedback device and an electronic device. The haptic feedback device includes: a haptic device to which contact pressure is applied; an actuator provided in the haptic device and excited according to a change in the contact pressure of the haptic device to generate vibrations; and a controller controlling the actuator to vibrate at a pre-set resonance frequency in a pre-set first operation mode and vibrate at a driving frequency different from the resonance frequency in a second operation mode set to be different from the first operation mode.
