The invention relates to an SOS system for ship wreck and belongs to the field of ultrasonic wave transmission. The SOS system comprises a button switch mounted in a cabin, a signal drive circuit mounted in the cabin, transmitting transducers distributed on the inner wall of the cabin, receiving transducers distributed on the outer wall of the cabin, a signal processing circuit, a marine satellite telephone equipment and coupling agents attached to the inner wall and the outer wall of the cabin, wherein the signal processing circuit and the marine satellite telephone equipment are mounted outside the cabin. The SOS system can overcome the defect that communication quality is reduced due to a skin effect of electromagnetic waves in metal surfaces during traditional wireless communication and can acquire and transmit SOS signals in a metal shielding body under the condition that the completeness of the cabin is not damaged, and accordingly, high-speed and errorless transmission of the SOS signals is realized. The SOS system is simple in structure and low in cost, can transmit the SOS signals in time when a ship wrecks, can also aid in quick positioning of trapped people and facilitates rescuing.
