MICRO ACTUATOR APPARATUS USING DISSIMILAR ELASTIC MATERIALS WHICH IS SUPPLYING TWO RESONANCE FREQUENCIES WITH TWO ELASTIC MATERIALS

摘要

PURPOSE: A micro actuator apparatus using dissimilar elastic materials is provided to supply two resonance frequencies from different values of an elastic coefficient and weights of two elastic materials, thereby maximizing magnetic force with a magnetism pass forming structure. ;CONSTITUTION: A micro actuator apparatus using dissimilar elastic materials is comprised of a magnetic force generation part(110), a solenoid part(120), a supporting unit(130), a first and second elastic material(131,132). The magnetic force generation part is a permanent magnet and attached to one side of the first elastic material. The first and second elastic material is established as a beam type or plate spring type. The solenoid part generates vibrations from magnetic repulsion using a magnetic field transformed from an applied voltage.;COPYRIGHT KIPO 2011
