Abstract:
A vibration device that includes a diaphragm having a perimeter; a film which expands and contracts in a planar direction by application of a voltage, and an electrode on each main surface thereof; and a wire extended from the electrode outside of the perimeter of the diaphragm. The diaphragm has a first region in a node of vibration and a second region in a position other than the node of vibration. The wire has a section extended from the second region toward the first region, or is extended from the first region outside of the perimeter of the diaphragm.
