摘要：A transducer assembly in which a transducer unit of a piezoelectric materialwhich is rigidly held between a rear member and a front member, both of which are madeto vibrate upon energizing the piezoelectric material. Inductive elements comprisingcopper conductors wound about iron cores and utilized in the tuning of the transducerassembly are rigidly connected to one or both of the members and may also beconnected to the transducer unit itself to serve as a portion of the inertial mass whichimparts a mechanical vibrational characteristic to the transducer assembly. In oneembodiment of the invention, the rear member is provided with a void wherein there isnested an inductor having an inertia similar to that of the material removed from the rearmember in forming the void.
