双锥面声透镜换能器的研究

Study on the Transducer with Bi-cone Lens

通过数值计算和实际测量 ,研究了双锥面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 ,且透镜的形状参数对声场分布有明显影响。

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.
