Abstract
A semi-wave transducer is provided that comprises a circular or elliptic transduction shell that has sidewalls captured between identical opposing upper and lower circular or elliptic conical segments (platens), each having a surface geometry of a radially symmetric wave shape that includes a center region and a rim wherein the distance between the center region of the upper and lower platens greater than the distance between the rims of the upper and lower platens. In some embodiments, the surface geometry of the platens may be a jinc function or a recurve function.
Claims3
A circular flextensional transducer comprising:
- first and second platens of semi-wave geometry, each platen having a positive semi-wave angle;
- and a transductive element secured between the rims of said first and second platens and that is coaxially aligned with said first and second platens, wherein each said first and second platens includes a hinge point, wherein said first and second platens each have a flat annular rim separated by top and bottom sidewalls, said hinge points abutting the top and bottom sidewalls.
