摘要 该文介绍了一种应用于 20 Hz ∼ 20 kHz 频段、最大工作深度 5000 m 的超高静水压水听器。水听器敏
感元件采用厚壁压电陶瓷圆管，高强度复合泡沫去耦，通过对敏感元件及水听器结构进行合理设计，保证水听
器具有高的耐压强度。测试了水听器在常压及不同压力下的接收灵敏度。测试结果表明，水听器常压下接收
灵敏度响应平坦，在常压到 50 MPa 压力范围内，水听器低频接收灵敏度最大变化小于 2 dB，表明该型水听器
具有良好的压力稳定性，可在深海资源勘测、深海通讯等方面获得广泛应用。

Abstract This paper introduces a high hydrostatic pressure hydrophone which is used in the 20 Hz–20 kHz
band and the maximum depth is 5000 meters. The sensor uses thick wall piezoelectric circular tube and high
strength composite foam to decouple. Through reasonable design of the structure, the hydrophone has high
pressure resistance. The sensitivity of the hydrophone under normal and different pressures is tested. The
test results show that the sensitivity of the receiver at atmospheric pressure is flat. In the 0.1 MPa–50 MPa
pressure range, the maximum change of the sensitivity of hydrophone at low frequency is less than 2 dB, which
indicates that the hydrophone has good pressure stability. It can be widely applied in deep resource survey
and deep sea communication.
