Mobile phone listening positioning technology

The invention discloses a mobile phone listening positioning technology. The invention aims to realize positioning and distance measurement of the direction of a sound source by using a mobile phone.According to the technology, a positioning microphone array is installed at a special position on the mobile phone, the microphone array comprises at least two microphones, and the two microphones areparallel to the long axis of the mobile phone and are installed at the positions as close as possible to the two ends of the mobile phone. When a sound source is positioned, a sound signal needing tobe positioned is selected through signal mode recognition; keeping the surface of the mobile phone horizontal, rotating the mobile phone in the horizontal plane, and calculating the direction vertical half-plane of the sound source according to the time difference of sound signals to be positioned reaching different microphones; then rotating the mobile phone in a direction perpendicular to the sound source in a semi-plane
