The vibration velocity information of water quality point cannot be obtained by the traditional sound pressure hydrophone to receive the signal in underwater acoustic communication system. In this paper, a vector hydrophone with a diameter of 38 mm and a height of 46 mm with the same vibration mode is developed, which can synchronously and co-located obtain the information of sound pressure and vibration velocity of water quality points, thus solving the problem of incomplete acquisition of 8~13 kHz signals by underwater acoustic communication system. The vector hydrophone adopts a specially designed integrated three-dimensional acceleration sensor with common inertial mass block, and the sensitivity of three axial directions in space reaches more than 328.0 pC/g. The PZT-5 piezoelectric ceramic ring is used as the sound pressure channel of vector hydrophone, the vector hydrophone prototype with x, y, z channel and p channel is developed and tested in the tank. The test results show that the sound pressure sensitivity level of x, y, z channel at 10 kHz is above -172 dB (0 dB reference value of 1 V/μPa), and it has good cosine directivity. The sensitivity level of sound pressure channel can reach -198 dB, which can be used for acquisition of 8~13 kHz signals in underwater acoustic communication.
