A mobile sound source positioning system is designed，which uses the principle of triangular parallax combined with sound intensity comparison method，receives sound source sound waves through sound sensors，displays sound intensity signals on embedded LCD displays，and automatically tracks sound sources according to decibel values and deflection angles．Compared to other sound sources that require a specific pulsed sound source positioning device，this device sensor can be used with any sound source．In addition，the system uses embedded sound sensor hardware filtering and software average filtering to reduce external noise interference and improve the positioning accuracy of the system．The hardware structure of the system is stable and easy to

implement，which is convenient for university laboratories to make themselves．
