Abstract
A flextensional transducer assembly having a single flextensional cell with a transducer housed with a platten. The transducer expands and contracts in a transverse direction to cause inverse movement in the platten in the axial direction. The platten may include either an elbow at the intersection of walls or corrugated pattern along the top and bottom walls. The platten is manufactured from one piece using Electrical Discharge Machining. A load is applied to the platten to then slot in the transducer into the platten before releasing the load to mechanically capture the transducer.
