本文通过研制适用于水声、超声的刚硬背衬ＰＶＤＰ微型环高频水听器，给出了 它的灵敏度、指向性以及频率响应等经验设计公式。对研制品的测量表明：计算与 实测是一致的。并得到在１００—５００ＫＨｚ频率范围内接收响应均匀的ＰＶＤＦ微型环高 频水听器。
In this paper, through the development of rigid backing PVDP mini-ring high frequency hydrophone suitable for underwater acoustic and ultrasonic, the empirical design formulas of its sensitivity, directivity and frequency response are given. Measurement of the product showed that: the calculation and measurement are consistent. And received in the frequency range of 100-500KHz receive uniform response PVDF micro ring high frequency hydrophone.
