Based on the problems of traditional broadcast system such as complexity wiring and low efficiency, this paper presents a design scheme of intelligent addressable broadcast system which takes the advantages of Zigbee and frequency modulation (FM) technologies. This system adopts a cluster topology structure with a master and numerous of broadcast nodes. The network management and system control is realized by Zigbee. The audio signal is transmitted via FM broadcast. Besides, we realized the upper computer software design based on Visual C. The practical test shows that audio quality and system efficiency are both greatly enhanced, and the broadcast system is low-cost, low-power and low-complexity.
