| description | The invention provides a vector sensor and sound field detection equipment, and relates to the technical field of sound field detection.The vector sensor comprises a base body, a first detection device and a second detection device; the base body is provided with a flow channel, the first detection device and the second detection device are arranged at intervals in the extending direction of the flow channel, and the first detection device and the second detection device are connected to the base body; and the sectional area of the flow channel is gradually reduced along the extending direction of the flow channel. The vector sensor and the sound field detection equipment provided by the invention can realize convergence enhancement of a sound field along a flow channel, have one-dimensional directivity, and improve the sensitivity of receiving sound waves in a specific direction.
本发明提供了一种矢量传感器及声场检测设备，涉及声场检测技术领域，本发明提供的矢量传感器，包括：基体、第一检测器件和第二检测器件；基体设有流道，第一检测器件和第二检测器件沿流道的延伸方向间隔设置，且第一检测器件和第二检测器件分别连接于基体；沿流道的延伸方向，流道 |
