An alternative formula for determining the volume-referenced, projector-transducer figure of merit, FOM(v), is developed allowing an evaluation based on well known parameters that may be readily calculated or measured. This formula is also reduced to the special case of piezoelectric or magnetostrictive materials, allowing a FOM(v) comparison of transducer materials in addition to an evaluation of specific transducer designs. Sample results are given for transducer materials alone and a PZT-8 driven modal projector transducer operated in the monopole mode.
开发了一种用于确定体积参考、投影仪换能器性能系数 FOM(v)的替代公式，允许基于可轻松计算或测量的已知参数进行评估。该公式还简化为压电或磁致伸缩材料的特殊情况，允许除了评估特定换能器设计之外，还可以对换能器材料进行 FOM(v)比较。仅给出了换能器材料的示例结果和在单极模式下运行的 PZT-8 驱动模态投影仪换能器。
