Title: Slotted cylinder acoustic transducer

Abstract: A slotted cylinder acoustic transducer assembly is provided that has a cylindrical housing shell and an electromechanical driver disposed within the shell. The driver is formed with a plurality of single crystal piezoelectric elements joined to the inner surface of the housing shell and arranged to form an electromechanical stack. Each piezoelectric element has a pair of sidewalls, wherein each sidewall provides an electrode having a predetermined polarity. Each single piezoelectric element has a tapering width between the sidewalls. The transducer assembly includes a plurality of electrically conductive members. Each conductive member is disposed between each pair of adjacent piezoelectric elements such that each electrically conductive member electrically contacts the electrodes of adjacent piezoelectric elements.
