Abstract
A piezo actuator module capable of haptic feedback in a wide frequency range comprises an actuator layer including a piezo actuator having one surface coupled to an object to be excited and vibrating by an electric signal and an inertial mass layer having a certain mass and coupled to the other surface of the actuator layer. The inertial mass layer supports the other surface of the actuator layer when the piezo actuator vibrates.
