摘要
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。
A dual sleeve type PVDF film hydrophone was developed by the authors. Using static analysis method, a low freguency electro-acoustic sensitivity formula was derived. Experimental hydrophone of this type with its measuring data shows bright prospect of its application.
