%X 部分铁氧体材料凭借其磁致伸缩效应，能有效地将电磁能转化为机械能和声能。针对这一现象，本文从实验上定量研究了商用镍锌和锰锌在交流磁场信号下的磁致伸缩现象，采集了相应的磁声信号，并系统研究了交流磁场频率、铁氧体棒的长度、材料类型、线圈电压等实验变量对磁声共振现象的影响。研究结果表明铁氧体的声学磁力谐振效应与交流磁场频率、铁氧体棒的几何形状、材料类型等参数精密相关，会对材料在具体应用时产生明显的影响。<br />
Some ferrite materials can effectively convert electromagnetic energy into mechanical energy and acoustic energy by virtue of their excellent magnetostrictive effect. In view of this phenomenon, the magnetostriction of commercial nickel zinc and manganese zinc under AC magnetic field signal is quantitatively studied experimentally, and the corresponding magnetoacoustic signals are collected. The effects of AC magnetic field frequency, ferrite rod length, material type, coil voltage and other experimental variables on the magnetoacoustic resonance phenomenon are systematically studied. The results show that the acoustic magnetic resonance effect of ferrite is closely related to the frequency of AC magnetic field, the shape of ferrite rod and the type of material. It will have a significant impact on the material in the specific application.
