Abstract:
A flap or diaphragm structure, comprising:a laminate film including: a first drive layer of a material having at least one of the properties selected from the group consisting of electrically conductive, magnetic and magnetically susceptible; a first layer of a dielectric material on a first side of the first drive layer; a second layer of a material on a second side of the first drive layer opposite the first side; a third layer; and a second drive layer formed on a surface of the third layer, the second drive layer being attached to a surface of the second layer opposite the first drive layer; and at least one electrode that actuates the laminate film, the at least one electrode positioned relative to at least one of the first layer and the third layer with a gap, wherein at least one of the first layer, the second layer, the third layer and one of the drive layers is anchored such that the flap structure is moved by electrostatic or magnetic force generated by the at least one electrode and acting on at least one of the drive layers.
