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。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 requirements of sound source telemetry system (sound wave transducer), the transducer is designed by using the magnetostrictive effect of the novel rare earth giant magnetostrictive material to transform the electro-magneto machine, so as to generate the sound wave through vibration and make use of the correlation The device radiates the sound waves out. Briefly introduced the working principle of the acoustic transducer, the main structure and the optimization design of each main part and the problems that should be noticed in the design.
