摘要： A piezoelectric loudspeaker includes a diaphragm and a piezoelectric element bonded on a principal surface of the diaphragm. An electrode layer is provided on the surface of the piezoelectric element. The piezoelectric element has a structure formed by alternately laminating at least three piezoelectric layers and electrode layers in order to achieve a sufficient driving force. A conductive path composed of a strip-shaped metal foil and having an adhesive layer on the reverse face thereof is provided on the surface of the electrode layer. The adhesive layer may be conductive or nonconductive. Conductive paste having a low rigidity and a low volume resistivity is applied so as to be disposed over the surfaces of the conductive path and the electrode layer. Thus, a conductive layer having a Young's modulus of 100 MPa or less and a volume resistivity of 6×10−3 Ωcm or less is provided.

摘要： A piezoelectric vibrator having excellent shock resistance and high reliability is offered. The centers of first and second piezoelectric vibrating plates are supported by pillars on a main surface of an enclosure and nearly or substantially parallel to the main surface of the enclosure. Spacers having a Young's modulus of less than 2 GPa are mounted on both end sides of the second piezoelectric vibrating plate to prevent contact between the vibrating plates, thus preventing damage. Other spacers are mounted on the main surface of the enclosure in positions corresponding to the first-mentioned spacers to prevent contact with the main surface of the enclosure, thus preventing damage to the second piezoelectric vibrating plate.

Provided is a piezoelectric oscillation device in which wiring is not easily broken. On the rear side of a touch panel (16), one main surface of a bimorph-type piezoelectric oscillation element (20) is entirely bonded via an elastic body (18) having a tensile elasticity of 20-100 MPa as measured according to JIS K7161. The piezoelectric oscillation element (20) has surface electrode layers (30A, 30B) connected to terminal electrodes (36A, 36B) via wiring lines (38A, 38B). The wiring lines (38A, 38B) are formed on top of a wiring protection layer (32) made of an elastic body provided on the rear side of the touch panel (16), and because the wiring lines can move following the displacement and are therefore resistant to breakage. When the piezoelectric oscillation element (20) is displaced toward the touch panel (16), it can transmit a greater amount of displacement to the touch panel (16) than when it is displaced to the opposite side.
