摘　　要：近年来,物联网应用中的信息采集和感知设备都在向小尺寸、低成本的方向快速发展。矢量传声器是一种先进的麦克风阵列,可以测量完整的声场矢量信息,能够大幅提高传声器对环境的感知能力和对数据的采集效率。由于矢量传声器是一种精密测量仪器,且价格昂贵,几乎没有应用于物联网信息感知的先例。基于此,笔者提出并设计一种低成本、小尺寸的矢量传声器原型,并搭建了信号采集测试平台,为实现独立矢量传声器的声源测向和定位奠定了基础。In recent years,information collection and sensing devices in IoT applications have been developing rapidly in the direction of small size and low cost.The vector microphone is an advanced microphone array that can measure complete sound field vector information,which can greatly improve the microphone's ability to perceive the environment and the efficiency of data collection.Since the vector microphone is a precise measuring instrument and expensive,there is almost no precedent for its application in Internet of Things information perception.Based on this,the author proposed and designed a low-cost,small-size vector microphone prototype,and built a signal acquisition test platform,which laid the foundation for the realization of independent vector microphone sound source direction finding and localization.
