摘　　要：介绍一种适用于物理实验教学的新型弦振动装置，描述了其基本结构及工作原理，并给出时基信号控制电路部分的PSpice仿真波形。该装置外型类似吉他，除具有传统弦振动装置的功能外，还可以调节振动频率，有效地实现了振动与发声的结合。The paper introduces a kind of new physics experimental teaching equipment on string vibration, mainly describes its basic structure and work principle, then gives the simulation wave form of the time- control electric circuit based on PSpice software. The equipment looks like a guitar, in addition to having a traditional function, also can regulate vibration frequency and effectively carry out combination of vibration and sound.
