从分布式压电源声激发原理出发,分析了具有不同空间畴结构和激发方式的声激发问题;提出和证明了用上述晶体激发高频体声波的可能性,并导出用上述晶体做成高频、高转换效率的压电换能器的输入阻抗或导纳的解析表式,这种换能器工艺比较简单。
Based on the theory of distributed piezoelectric source acoustic excitation, the acoustic excitation problems with different spatial domain structures and excitation modes are analyzed. The possibility of using the above crystal to excite high frequency bulk acoustic waves is proposed and proved. , High conversion efficiency of the piezoelectric transducer input impedance or admittance analytic table, this transducer process is relatively simple.
