ABSTRACT:
A transducer composed of a plurality of transducer segments arranged along a line with electrodes positioned between the segments and a pair of end electrodes positioned at opposite ends of the line of transducer segments. The two end electrodes are electrically coupled. Alternate ones of the remaining electrodes are coupled to the terminal pair of a signal generator which electrically activates the transducer segments to convert the electrical signals to vibrational energy for the radiation of sonic energy from the transducer. This arrangement reduces the electrical potential between the electrodes and a metallic case which encloses the transducer.
