针对现有语音侦听设备中存在的布设困难、价格昂贵和功耗高等问题，提出了基于 CC2530的语音侦听节点设计方案。该方案采用 CMX649芯片作为语音感知模块来完成语音信号的检测、采样和编码。采用 CC2530作为核心处理器模块来完成节点的控制、数据的处理及无线传输。TPS780330220产生稳定的3.3 V 电压，可维持节点的正常运行。测试结果表明，该节点能稳定地实现语音信号的实时采集与无线传输，具有体积小、使用方便、成本低、功耗低和侦听距离远的特点。

Aiming at the issues such as painful operation,valuableness and high power consumption of the equipment of voice intercep-tion,the voice listener node design based on CC2530 is proposed.It makes CMX649 chip as the voice apperceived module to complete voice signal's collection,sampling and coding.It makes CC2530 as the core microprocessor moudle to control the node,treat and trans-mit the data wirelessly.Producing steady 3.3 V voltage by TPS780330220.The testing result shows that this voice interception can col-lect the voice signal in real time and transmit wirelessly steadily.It has the characteristics of small size,flexible operation,low cost and low power consumption,and the farness disstance of interception.
