摘　　要：通过改进部分电路完善了特雷门琴的现代设计,其输出声音的音调和音量可通过演奏者的双手无接触控制.通过模块化设计和SPICE模拟后成功制作了低成本的特雷门琴装置,实现了电子乐器的功能.设计制作过程中多处应用了LC振荡电路,加深了学生对模拟电路原理的理解,并提高了学生动手解决实际问题的能力.The modern design of the Theremin was perfected by modifying the circuits partly.The tone and volume of the voice output could be controlled untouched by the palyers＇ hands.The lowercost Theremin was made by modular design and SPICE simulation.And the function of the electronic musical instrument was implemented.The LC oscillators were applied in the design,which could deepen the understanding of the principle of analog circuitry and foster the students＇ ability to operate practically.

关 键 词：特雷门琴 LC振荡电路 SPICE模拟 电子乐器
