摘　　要：介绍一款基于mega16单片机的声多普勒效应实验仪,给出了实验仪各部分的软硬件设计方案及实验测试结果。采用模块化设计方法,利用按键控制超声波换能器的运动方向与速度,可以展示多种情况下的声多普勒效应。测试表明该实验仪具有很强的独立性,适用于实验教学。An audio Doppler Effect experimental apparatus based on megal6 microcontroller is introduced in this article The software and hardware design of various parts of experimental apparatus are given as well as the experimental test results. With modular design, the movement direction and the speed of the ultrasonic transducer are controlled by the use of buttons. A variety of cases of the audio Doppler Effect could be displayed. The test indicates that the instru- ment has a strong independent character, especially for experimental teaching.
