本文利用外信号对声光双稳系统混沌进行了扩展研究，在此基础上提出了基于声光双稳系统混沌通信的方案，并进行了此混沌保密通信的数值模拟．
In this paper we have Researched the extended acousto-optical bistable chaos system with input signal, and find that the system is still in chaos regime while select properly intensity of the signal. Then base on this extended acousto-optical bistable chaos system, we give a method for communication with the expended acousto-optical bistable chaos system.
