Design of a Sound Source Multidimensional Positioning System Based on TDOA

The sound source multidimensional positioning and tracking system designed here is composed of microphone array, two-dimensional cradle head, power step-down device, laser indicating device, LCD display and main control MAIX Dock. The microphone array is the data acquisition part, the two-dimensional cradle head and laser indicating device is the action execution part, LCD display is the data display part, and MAIX Dock is the control core. It can realize accurate sound source positioning, and mark the position of the sound source by laser. It has strong anti-interference ability, and can dynamically track the moving sound source, and describe the motion trajectory of the sound source through the display screen.
