摘要
从理论上计算凹球面型换能器的声压的分布原理,利用Matlab和Mathamatic软件对不同孔径下焦点附近声压的分布变化进行了模拟计算,给出了不同情况下声压强度和焦斑的范围.这对于聚焦换能器在医学上的应用具有一定的参考意义.
This paper studies distribution in sound field of the concave spherical transducers under different conditions. Theoretically, it first calculates the sound pressures distribution. Distribution of different apertures near the focus of sound pressure is simulated by using Matlab and Mathamatic software.The sound pressure level and the focal range are provided in different situations.This has certain reference significance for the application of transducer in medical science.
