Abstract

The haptic actuator needs to downsize in the mobile devices continuatively. In this work, the hinge lever mechanism was used in order to prevent lowering the vibration performances of the downsized actuator. The vibration performances of actuator with and without hinge-lever mechanism were simulated by the finite element method analysis. It is concluded that the hinge-lever mechanism may be a proper measure to prevent lowering the vibration performances in the downsized piezoelectric actuator.
