Abstract
[Problems] To provide a multifunction vibration actuator which has flat rising and falling frequency characteristic at the time of generation of bodily sensation vibration and which is stable for an input signal. [Means for Solving Problems] Flat frequency characteristics can be obtained by using a two-fold rotational symmetry frame type suspension, and miniaturization of the whole multifunction vibration actuator can be made by the user of the frame type suspension. With regard to the frame type suspension, use of protruded configuration of corner parts ensures the effect of absorption of deflection of the suspension.
