Abstract: A vibrating device that includes a pair of vibrators, a vibrating body that includes a conductor, a touch panel sensor that includes touch sensors, and a printed circuit board on which a drive circuit is formed. The touch panel sensor is attached to one principal surface of the vibrating body. Moreover, both ends of the vibrating body on the other principal surface of the vibrating body are fixed to the pair of vibrators. The vibrating body is a conductor that is arranged between the touch sensors and the drive circuit. The conductor is connected to a reference potential of each touch sensor and the printed circuit board is positioned between the two vibrators.

Abstract: The vibration device includes a diaphragm, and a plurality of piezoelectric films that are arranged at predetermined intervals in a first direction of the diaphragm to face the diaphragm and extend parallel to a second direction orthogonal to the first direction. The diaphragm has at least one slit formed therein and dividing the diaphragm into respective regions. Each of the piezoelectric films are fixed to a respective region of the diaphragm while extending along the second direction in a tensioned state. The piezoelectric films expand and contract in a plane direction when a voltage is applied thereto.

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.
