For many hydrophone applications in underwater acoustic fields, there is a great demand for vector sensors with the higher sensitivity and easily using. A high sensitivity and strong anti-jamming co-vibrating vector sensor has been described in this paper. The vector sensor with acoustic pressure channel and vector channel can be fixed in any carrier. The length of sample is 166 mm and diameter is 50 mm. The experimental results show that the cylindrical co-vibrating vector sensor has good cosine directivity and the sensitivity of vector channel is −181dB at 1kHz (re 0 dB=1V /µ Pa), and the average acoustic pressure sensitivity is −190dB (re 0 dB=1 V /µ Pa) over the frequency range of 20 Hz to 1600 Hz.
