| 摘 要： | 基于CD4011的声光控延时小夜灯系统，核心部分是由三极管、光敏电阻器、电容等分立元件和CD4011集成芯片构成的，可分为整流、声控电路、光控电路三个部分。整流电路主要由整流桥来实现交流到直流之间的转换，并在直流电过零点处实现小夜灯的自动关断；声控电路和光控电路则主要由驻极体和光敏电阻来构成。

| Abstract: | The system of acoustooptic night light based on CD 4011 is consisted by dynatron,photoresistor and CD4011 inte-grated chips,which can be divided into rectification,sound control circuit and light control circuit .The tectification circuit u-ses the rectifier bridge to realize the transition from alternating to direct current and the night light will be turned off auto -matically when the direct current gets zero.The sound and light controlled circuits are made of electret and photoresistor. |
