1. A haptic actuator, comprising:
- a vibration mechanism having a movable element,in response to a receipt of a first driving current, vibrates said movable element at a first vibration acceleration having a first amplitude along a plane of a surface of a device to which said haptic actuator is attached;
in response to a receipt of a second driving current larger than said first driving current, vibrates said movable element at a second vibration acceleration having a maximum amplitude higher than said first amplitude along said plane of said surface of said device; and
a striking mechanism, in response to a receipt of said maximum amplitude of said second vibration acceleration higher than said first amplitude of said first vibration acceleration, strikes said surface of said device.

Abstract
A haptic actuator for generating haptic feedbacks to provide perceptions of different characteristics is provided. The haptic actuator includes a vibration mechanism and a striking mechanism. The vibration mechanism, in response to a receipt of a predetermined electric power, applies a steady vibration to a vibrating body. The striking mechanism, in response to the receipt of an electric power larger than the predetermined electric power, strikes the vibrating body in order to provide a haptic feedback to the vibrating body. The haptic actuator is able to apply a vibration according to the vibration mechanism and a vibration according to the striking mechanism to the vibrating body.
