description The utility model discloses a parametric array sound emergency evacuation system. Wherein the first communication module is used for receiving emergency information, the micro-processing unit is usedfor receiving the emergency information sent by the first communication module and providing an emergency plan according to the emergency information, the control center is used for receiving the emergency plan sent by the micro-processing unit, and the voice module is preset with voice information. Wherein the parametric array module is used for converting voice information into ultrasonic modulation signals and transmitting the ultrasonic modulation signals to air to restore sound production, and the control center, the first communication module, the micro-processing unit, the voice moduleand the parametric array module are connected in sequence. When an emergency event occurs, through the high-directivity sound of the parametric array technology, due to the fact that smoke can hurt eyes and cannot affect heari
