摘要： A multi-segmented flextensional transducer includes a plurality of electroplated electroactive members which deform in concert when energized by an electrical field. Each electroactive member has a convex surface at both ends. A connection member with opposing concave surfaces is disposed between adjacent electroactive members. The electroactive members are arranged such that the convex faces of each intermediate electroactive member engage a concave face of an adjacent connection member, thus forming a cooperative array or "train" of electroactive members and connection members. The opposite ends of the train of electroactive members and connection members is received by a frame which holds the end electroactive members in fixed relative position. The electroactive members are high deformation flextensional piezoelectric elements. When energized, each electroactive member individually deforms, and the entire array deforms in concert an amount significantly exceeding that of the individual electroactive members.
