Beschreibung
Zusammenfassung:	A piezoelectric transducer for use in an ink jet print head is disclosed. The ink jet print head defines an ink pressure chamber that further defines a chamber aperture having an overlaying flexible diaphragm. The piezoelectric transducer has a top side, an under side secured to the flexible diaphragm and an outer perimeter sized and positioned to overlap the chamber aperture wherein the overlap improves process capability and reduces voltage sensitivity.
