摘要
较全面地分析了常见的音控电路及音控IC模块,这些电路都具有不需专用的发射装置,电路较简单可靠,但抗干扰能力较差。而多路音控电路及IC模块一般只能进行顺序控制;且控制路数较少的缺陷。采用最常见而廉价的电子元件,采用理论分析计算与设计安装调试相结合的办法,设计制作出一种新型的,具有一定抗干扰能力的,能任意控制多路输出的音控电路,而且得到满意效果。
This paper analyzes a familiar sound control circuit and sound control IC module extensively. The circuit normally dosn＇t need special transmitting devices, it is simple and liable, but the anti-interference＇s ability often is poor. At the same time,the multiplex sound control circuit and IC module only carry on an order control generally,and there is a defect,that is, control paths are less. This paper designs and makes a new type of sound control device which with a multi - path output,anti-interferencers ability and can be freely controlled through using cheap electronic components, theories analysis, calculation, designing, installing and debugging, agreeable result is obtained.
