Haptic feedback actuator, haptic feedback device and electronic device

摘要

There is provided a haptic feedback actuator, a haptic feedback device and an electronic device. The haptic feedback actuator includes a support plate disposed in a lower portion of a haptic device; one or more actuators disposed on the support plate, each having one end towards a central portion of the support plate and the other end towards a corner of the support plate, and generating vibrations so as to give different types of haptic feedback according to a change in contact pressure applied to the haptic device; and one or more dividing portions, each penetrating the support plate in a thickness direction thereof and dividing the support plate into vibration areas corresponding to the respective actuators.
