摘　　要：本文比较几种激光竖琴电路设计方案和优缺点,介绍了一种激光竖琴的电路设计。本文重点介绍了音乐芯片YM-6100的键盘矩阵的两种实现方式:单片机中断模式实现和硬件译码直接实现,还介绍了单片机控制音乐芯片进行自动音乐播放的原理和对应的编码译码方法。This paper compares the design methods, advantages and weaknesses of several kinds of laser harps, and introduces the circuit design of a kind of laser harp. This includes the laser harp circuit block diagram, the chip selection of peripheral circuits. The emphasis is the introduction of two kinds of realization modes of music chip YM- 6100 keyboard matrix： MCU interruption mode and hardware decoding mode. This Paper also introduces the theories of auto-playing music for MCU to control music chip YM-6100, and the corresponding coding and decoding methods.
