In addition, due to frequent switching, or other man-made factors, the failure rate of a high wall switch, both increasing the amount of maintenance, waste of funds, but also easily lead to accidents. Therefore, the circuit design and development of a novel, safe energy-saving, simple structure, easy to install voice-activated energy-saving automatic switch corridor lights appeared to be quite necessary.To make public places and those who are living in the public corridor lights during the day without light at night from Wen Sheng-liang, treat people left, tens of seconds automatically shut down, which is convenient, but also energy saving. The following introduces the principle of voice-activated switch. Keywords: Circuit bord Voice-activated switch Contro1 Power摘 要 II ABSTRACT 3 第1章 声控灯工作原理 5 第2章 声控灯的制作 6 2.1 设计方法 6 2.1.1 直流供电电路 6 2.1.2 控制电路控制电路 6 2.1.3延时电路 7 2.2 元器件的介绍 7 2.2.1 光敏电阻 7 2.2.2 驻极体话筒 7 2.2.3 NPN三极管 9 2.2.4 可
