Abstract
Sound fields generated by transducers with bi cone lens are studied through numerical calculations and experiments.The results indicate:a narrow sound beam over a longer axial range can be obtained by bi cone lens,and sound field characteristics are greatly affected by shape parameters of the curved surface.
