声光控元件性能模拟演示器的设计与制作

通过用声、光敏传感器等常用电子元器件设计制作声、光控电路模拟演示器,利用LED发光管的有序流动效果模拟演示声光控元件的导通性能,这对声光控原理的讲述起到画龙点睛的效果,由于该演示电路的创新之处是将声光控及闪光电路集为一体,简单明了,说服力强,便于学生实际动手操作,加深学生对传感器知识的理解,激发学生学习的探索欲望,使老师的教学可取得很好的教学效果.

Design and production of sound and light control components properties analog demonstrating device

By using sound or light sensors and other commonly used electronic components,we design and produce a simulation demonstrator of sound and light control circuit,and use the orderly flow effects of LED light tubes to demonstrate the conduction properties of sound or light control components.It is very helpful to teach the principle of sound and light control as this demonstrating method is very innovatively integrated the sound or light control with the flashing circuit together,making the demonstration is simple,persuasive,and easy for facilitate students practical hands-on.It will enhance the students’ understanding to knowledge of sensors,encourage them to explore more,and improve the teaching effect of teachers.
