本文提出一种采用PVDF聚合物薄膜作为压电材料的双套筒式水听器结构,并通过静态分析方法给出了水听器的低频电声灵敏度公式。理论优化值及一例该结构式水听器的实测结果均表明,这种结构具有乐观的应用前景。
In this paper, a dual-sleeve hydrophone structure using PVDF polymer film as piezoelectric material is proposed. The sensitivity of low-frequency electro-acoustic sensitivity of hydrophone is given by static analysis method. Theoretical optimization and an example of the structure of hydrophone measured results show that this structure has an optimistic outlook.
