摘　　要：根据声波遥测系统对声源(声波换能器)的要求,利用新型稀土超磁致伸缩材料的磁致伸缩效应设计换能器实现电-磁-机的转化,从而通过振动产生声波并利用相关装置将声波辐射出去。文章简单介绍了声波换能器的工作原理,主要结构及各个主要部件的优化设计及设计中应注意的问题。According to the requirement of the acoustic telemetry system for source of sound,using a new kind of rare earth giant magnetostrictive material designs a transducer,and using magnetostrictive effect realizes electrical and magnetic-machine transformation,sound waves produce through the vibration and then the sound waves radiate through relative device.This paper briefly introduces the working principle,the main structure and major part optimized design of the acoustic transducer,and the paper emphasizes design problems should be paid attention to.
