Abstract

The invention provides a sound detection and positioning system, and the system comprises a sound sensor array and a sound wave conduit array, wherein the sound sensor array comprises N sound sensor units, and N is not less than two. The sound wave conduit array comprises M sound wave conduits, wherein M is not less than two. Two ends of each sound wave conduit are opened and connected and are shaped like a circular pipe, wherein one end of each sound wave conduit is connected with the corresponding sound sensor unit, and the other end of each sound wave conduit is disposed in the air. A sound signal transmitting in the air enters into the sound wave conduits of the sound wave conduit array, and then is received by the sound sensor units of the sound sensor array. The system is small in size, is light in weight, and is portable. The sound sensor array is compact in structure, and difference on the sound sensor units from an external environment is small. The measurement accuracy of the system is high.
