摘　　要：针对现有红外耳机的稳定性差、性能较低、易受干扰等弊端,设计了一款红外无线耳机装置.该装置是以红外光为载波传递音频信号的光电传输系统,由发射部分和接收部分组成.微控制器采用STC89C52单片机,配合AD9851、LM386和DAC0832控制音频信号的调制和解调.实验结果表明,该红外耳机系统稳定,控制灵活,辐射范围较大,信号较强,音量可调.一个红外发射可以有多个红外接收.Aiming at defects of the existing infrared earphones,such as poor stability,low performance,vulnerable to interference and so on,a new wireless infrared earphones system was designed. The system was optical transmission system which transferred audio signal in the infrared light as the carrier. It was composed of transmitting part and receiving part. The microcontroller was STC89C52 with the modulation and demodulation of AD9851,LM386 and DAC0832 to control the audio signal. The experimental results showed that the infrared earphones system had the advantages of the better stability,flexible control,large radiation range,strong signal and adjustable volume. An infrared emission could have multiple infrared receivers.
