The invention provides a vector sound water sensor. The vector sound water sensor comprises a substrate, a vector chip and a water sound receiving piece, wherein the vector chip is arranged on the substrate, the water sound receiving piece is connected with the vector chip, the vector chip comprises a silicon substrate, a water sound measurement piece, chip pins, TGV glass and metal via holes, thewater sound measurement piece is arranged on the silicon substrate along at least two different directions, the metal via holes are formed in the TGV glass, the TGV glass is sandwiched between the substrate and the silicon substrate, the chip pins are respectively connected with the water sound measurement piece and the metal via holes, the water sound receiving piece is used for receiving a vector water sound signal, the water sound measurement piece is used for converting the vector water sound signal to a vector electrical signal, and the TGV glass is used for sealing the chip pins and sending out the electrical signals by the metal via holes. By the vector sound water sensor, a sound field vector signal can be measured, the positioning accuracy is improved, an external water environment medium can be in direct contact, a sound transmission cover is not needed to be arranged, the energy loss brought by the sound transmission cover is prevented, the sensitivity is improved, the sizeis small, the volume of a sonar system can be reduced, and the implementation difficulty of sonar system engineering is reduced.
