ABSTRACT:
A pre-stressed, sandwich-type, ultrasonic transducer assembly includes front and rear mass members having stacked therebetween alternating piezoelectric members and electrode members, with each of the members having surfaces which are substantially flat except for minute surface irregularities. Thin, soft, aluminum foil washers are respectively disposed between the facing surfaces of adjacent members of the stack. At least one bolt joins the front and rear mass members to subject it to a compressive pre-load, under which load the washers deform to follow the surface irregularities of the adjacent member surfaces and thereby fill inter-element voids created by such irregularities.
