摘　　要：现阶段家用音响系统采用有线方式布线复杂、不易改动,而采用蓝牙技术无线传输音频数据系统成本过高。基于以上问题,设计了以TI公司的MSP430F1611为主控芯片,控制USB接口芯片CH375读取U盘内mp3音频文件,并将其数据流通过ZigBee网络传送给分节点,最后经音频解码芯片VS1003解码输出的低成本、低功耗无线音响系统,将嵌入式USB主机和ZigBee技术创新性地应用于家用音响系统的无线数据传输。Currently,the wired mode in household audio system is complex and difficult to change,whereas it costs too much to use Bluetooth to transmit aundio data.Based on these issues,we design a low-cost,low-power wireless audio system which uses TI＇s MSP430F1611 as the master chip to control the USB interface chip CH375 to read mp3 audio files inside a U disk,and transmits the data streams through ZigBee network to the sub-node,then decode and output the signal by audio decoder chip VS1003.It innovatively uses embedded USB-HOST and ZigBee technology in domestic sound system and achieves the wireless transmission of audio data.
