摘要
通过数值计算和实际测量,研究并证实了凸面-锥面声透镜聚焦换能器产生的声场,能产生较细长的聚焦声束,并且透镜的形状参数对聚焦声场分布有明显影响。
Sound fields generated by transducers with convex-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 convex-cone lens,and sound field characteristics are greatly affected by shape parameters of the curved surface.
