| 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. |
| Keywords: | focusing lens acoustic field |
