摘要
通过数值计算和实际测量 ,研究了球面 -锥面声透镜聚焦换能器产生的声场 ,证实其能产生较细长的聚焦声束 。
Sound fields generated by transducers with sphere cone acoustic lens are studied through numerical calculations and experiments.The results indicate:a narrow sound beam over a longer axial range can be obtained by sphere cone acoustic lens,and sound field characteristics are greatly affected by shape parameters of the curved surface
