摘　　要：红外线接收音频信号系统,是通过接收以红外线作为载波的光源,再把收到信号解调回原音频的过程。发射光源选取红外光优点则在于不容易被其他电器干扰,保密性能好。本文探讨如何设计和运用红外线音频信号接收遥控系统去实现声音通信,并利用红外线遥控的方式实现音量的加减控制和系统电源的管理。IR receiver audio signal system receipts light source with infrared as carrier,and then demodulates received signal back to the original audio.Infrared as light source has the advantage that it is not easy to be interfered by other electrical,and security.This article discusses how to design and use infrared audio signal inception remote control system to achieve voice communications,and use infrared remote control means to achieve the addition and subtraction control of the volume and system power management.
