Claim 2:
3. A flextensional amplifier comprising:
a linear transducer;
an innermost flexible member having an innermost elongated shape with an innermost minor axis and an innermost major axis, said innermost minor axis being perpendicular to said innermost major axis, said innermost minor axis being shorter than said innermost major axis, said linear transducer being joined to said innermost flexible member where the innermost major axis contacts the innermost flexible member;
at least one outer flexible member sized to accommodate at least one smaller flexible member and positioned about the smaller flexible member, the innermost outer flexible member being positioned about said innermost flexible member, each said outer flexible member having an outer elongated shape with a sized outer minor axis and a sized outer major axis, said sized outer minor axis being smaller than said sized outer major axis, said outer flexible member being joined at the sized major axis to the smaller flexible member at the smaller flexible member minor axis whereby the outermost of said at least one outer flexible member provides amplified motion of said linear transducer at the sized outer minor axis thereof; and
a plurality of linear members connecting a smaller flexible member minor axis to said outer flexible member sized major axis wherein said innermost flexible member has a higher stiffness than said at least one outer flexible member, and said successive outer flexible members each have a lower stiffness than the smaller flexible member.
