Abstract
Official abstract text for this publication.
In a piezoelectric oscillation device in which a support substrate is oscillated using a bimorph-type piezoelectric oscillation element, the click sensation when the support substrate is operated is improved, and shock resistance of a control panel is improved. 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 ( 30 A, 30 B) connected to terminal electrodes ( 36 A, 36 B) via wiring lines ( 38 A, 38 B). The wiring lines ( 38 A, 38 B) 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A piezoelectric oscillation device, comprising: a support substrate; and a piezoelectric oscillation element that causes the support substrate to vibrate, wherein the piezoelectric oscillation element is a bimorph piezoelectric oscillation element, wherein one main surface of the piezoelectric oscillation element is entirely bonded to the support substrate through an elastic body having a tensile elasticity of 20 to 100 MPa as measured in accordance…
