  • Piezoelectric diaphragm structure with outer edge electrode
    Publication number: 20050134153
    Abstract: A multi-electrode piezoelectric diaphragm structure includes a diaphragm, piezoelectric material located on the diaphragm, which is defined as having a first area, and a second area. The first area of the piezoelectric is poled in a first direction, and the second area of the piezoelectric is poled in a second direction. The poled first direction is in a Z-axis of the piezoelectric and the poled second direction is in a Radial axis of the piezoelectric. A first electrode is positioned in the first area, on the first surface, of the piezoelectric. A second electrode is positioned in the second area, on the first surface, of the piezoelectric. A third electrode is located on a second surface of the piezoelectric.
