基于单片机的无弦奏乐电子琴设计

Design of No Strings Played Electronic Organ Based on MCU

电子琴是现代电子科技与音乐结合的产物,是一种新型的键盘乐器。它在现代音乐中扮演着重要的角色,单片机具有强大的控制功能和灵活的编程实现特性,它已经溶入了现代人们的生活中。本设计创造性地通过红外对管进行音符判断,取代了传统的按键,控制单片机自身的定时器输出频率从而带动扬声器发出不同的音调。主要阐述了该电子琴的硬件和软件部分的设计思想,并进行了实物测试,具有较高的使用价值。

The electronic organ is a modern electronic music technology and the product is a new type of keyboard instruments. It plays an important role in modern music. SCM has powerful control functions and flexible programming characteristics, it has converged with the modern people＇s life. This design creatively through the infrared tube to determine the note, instead of the traditional button, control the microcontroller＇s own timer output frequency to drive the speaker to send a different tone. This paper mainly describes the design of hardware and software of the electronic organ, and a physical test, it has higher use value.
