Abstract
A piezoelectric transducer module includes first and second transducer units, each of which includes a conductive substrate portion that extends in a first direction and that has first and second surfaces opposite to each other in a second direction transverse to the first direction. At least one of the first and second surfaces has a piezoelectrically active coating coated thereon. The first and second transducer units are spaced apart from each other in the second direction. A connecting unit extends in the second direction and has opposite ends connected to the substrate portions of the first and second transducer units, respectively. The substrate portions of the first and second transducer units and the connecting unit are formed from a unitary conductive plate that is folded at junctions of the connecting unit and the substrate portions of the first and second transducer units.
