〔一〕实验目的
1．了解计算机发声原理。

2．熟悉定时器和键盘扫描电路的工作原理及编程方法。

〔二〕设计任务及要求
利用实验平台上的开关k0-k7和蜂鸣器设计电子音调发生器，要求：
1．利用实验平台上开关k0-k7进展音调选择，即拨动不同的开关产生不同的音调，依次拨动K0~K7，蜂鸣器发出1234567i八个音调。

2．编写2支歌曲，并可进展选择播放。

〔三〕工作原理及设计思路
音节由不同频率的方波产生，音节与频率的关系如表1所示。

要产生音频方波，只要算出*一音频的周期〔1/频率〕，然后将此周期除以2，即为半周期的时间。

利用计时器计时此半周期时间，每当计时到后就将输出方波的I/0反相，然后重复计时此半周期时间再对I/O反相，就可在I/O脚得到此频率的方波。

在ZKS-03实验仪上，产生方波的I/O脚选用P1.7，通过跳线选择器JP1将单片机的P1.7与蜂鸣器的驱动电路相连。

这样P1.7输出不同频率的方波，蜂鸣器便会发出不同的声音。

另外，音乐的节拍是由延时实现的，如果1拍为0.4秒，1/4拍是0.1秒。

只要设定延时时间，就可求得节拍的时间。

延时作为根本延时时间，节拍值只能是它的整数倍，
每个音节相应的定时器初值*可按下法计算：
〔1/2〕*(1/f)=(12/fose)*(216-*)
即*=216-(fose/24f)
其中f:音调频率，当晶振fose=11.0592MHz时，音节“1〞相应的定时器初值为*,则可得*=63777D=F921H 其它的可同样求得。

表1
〔四〕实现功能设计
实现两个主要功能：电子琴与音乐播放；一个辅助功能：在液晶上显示相关信息。

1、电子琴：4*4的矩阵16个按键，按键0实现两个功能的切换，其余按键分别发出音调低音5、6、7，中音1、
2、
3、
4、
5、
6、7，高音1、2、3、4、5。

发音的同时在液晶显示屏上显示出对应的音调。

2、音乐播放：按键0实现两个功能的切换，按键1实现播放类型选择〔单曲循环播放、所有循环播放〕，其余按键分别对应一首歌。

目前已经有9首歌。

播放的同时，在液晶上显示出歌名。

〔五〕软件设计
根据要实现的功能，流程图如下：
*include <AT89*52.H>
*include <intrins.h>
*define BEEP P3_3
