单片机蜂鸣器奏乐实验大全代码
蜂鸣器歌唱原理以及代码
3.3 蜂鸣器播放歌曲原理一般说来，单片机演奏音乐基本都是单音频率，它不包含相应幅度的谐波频率。
因此单片机奏乐只需弄清楚两个概念即可，也就是“音调”和“节拍”。
音调表示一个音符唱多高的频率，节拍表示一个音符唱多长的时间。
1）音调的确定音调就是我们常说的音高。
它是由频率来确定的！我们可以查出各个音符所对应的相应的频率，那么现在就需要我们来用51来发出相应频率的声音！我们常采用的方法就是通过单片机的定时器定时中断，将单片机上对应蜂鸣器的I/O口来回取反，或者说来回清零，置位，从而让蜂鸣器发出声音，为了让单片机发出不同频率的声音，我们只需将定时器予置不同的定时值就可实现。
2）节拍的确定一般说来，如果乐曲没有特殊说明，一拍的时长大约为400—500ms 。

单片机蜂鸣器音乐
单片机蜂鸣器音乐单片机在我们的生活中无处不在，它被广泛地应用在各种电子产品中，为我们的生活带来了便利。
今天，我要向大家介绍的是一种基于单片机的蜂鸣器音乐播放器。
一、硬件部分1、单片机：我们选用的是AT89C51单片机，它具有低功耗、高性能的特点，非常适合用于音乐播放器。
2、蜂鸣器：蜂鸣器是用来发出声音的，我们将其连接在单片机的输出口上。
3、存储芯片：为了能够播放存储在芯片中的音乐，我们需要将音乐以某种格式存储在芯片中。
常用的存储芯片有EEPROM和Flash芯片。
4、按键：为了能够选择播放不同的音乐，我们需要添加一个按键。
二、软件部分1、音乐编码：我们需要将音乐转换成二进制编码，这样才能被单片机读取并播放。
常用的音乐编码格式有MIDI、WAV等。
2、音乐播放：当按下按键时，单片机读取存储芯片中的音乐数据，并通过蜂鸣器播放。
3、音乐选择：通过按键可以选择不同的音乐进行播放。
4、音量控制：我们可以通过编程来控制蜂鸣器的音量大小。
三、调试与测试1、硬件调试：检查连接是否正确，确保没有短路或断路的情况。
2、软件调试：将程序下载到单片机中进行调试，确保能够正常播放音乐。
3、综合测试：将所有硬件和软件都连接起来进行测试，确保能够正常工作。
四、总结与展望通过本次实验，我们成功地制作了一个基于单片机的蜂鸣器音乐播放器。
它具有简单、实用的特点，可以用来播放存储在芯片中的音乐。
未来，我们可以进一步扩展其功能，例如添加更多的按键来选择不同的音乐、添加显示屏来显示歌曲名称等。
我们也可以将其应用到其他领域，例如智能家居、智能安防等。
单片机蜂鸣器唱歌程序在许多应用中，单片机蜂鸣器经常被用来发出声音或音乐。
下面是一个使用单片机蜂鸣器唱歌的程序示例。
我们需要确定单片机和蜂鸣器的连接方式。
通常，单片机具有一个内置的蜂鸣器输出引脚，可以将蜂鸣器连接到这个引脚上。
在以下的示例中，我们将假设单片机具有一个内置蜂鸣器输出引脚，并将其连接到P1.0端口上。
单片机控制蜂鸣器鸣奏音乐
单片机控制蜂鸣器鸣奏音乐——中北大学：马政贵首先介绍蜂鸣器的发声原理。
我们都知道，音调和音调的时长是音符的主要特征，通过产生不同的音调和音调的时长可以奏出不同的音符来。
然后一个个音符串联在一起就可以产生美妙的音乐来了。
音调主要由声音的频率决定，通过单片机给蜂鸣器不同的音频脉冲来产生不同的音调。
要产生音频脉冲，只要算出某一音频的周期（周期=1/频率），然后将此周期除以2即为半周期的时间。
利用单片机的定时器工作在计数模式MODE1下，设定TH0和TL0的值以产生这半个周期，每当计时到达时就将输出脉冲的I/O（即接蜂鸣器的那个管脚）反相，然后重复计时此半个周期再对I/O反相，就可以在I/O引脚上得到此频率的脉冲。
如果没有必要进行精确的计时，可以用for循环空语句来粗略计时即可（本文选用此法）。
当单片机使用11.0592Mhz的晶振时，for(i=0;i<115;i++);这个空循环延时约为1ms；当晶振选用12Mhz时，可使用for(i=0;i<125;i++);这个空循环来延时1ms。
在这个空循环外头再进行一次循环就可以实现延时若干ms。
如：知道如何产生不同的频率的音调和进行音调的延时的之后，我们便可以编写程序来让单片机控制蜂鸣器来鸣奏音乐了。
下面附上不同音调所对应的频率表：下文介绍了让单片机控制蜂鸣器进行鸣奏音乐的两种方法。
第一种方法是基础的方法，就是顺序地让蜂鸣器挨个地演奏每个音符。
方法一：（此歌曲是《莫斯哥郊外的晚上》的乐曲）#include <reg52.h>sbit fmq=P3^6;void delay(unsigned int a){unsigned char b;while(a--){for(b=0;b<115;b++) ;}}void yanzou(unsigned char i,unsigned int pai){unsigned char y;unsigned int j;for(j=0;j<pai;j++){fmq=0;for(y=0;y<i;y++) ;fmq=1;for(y=0;y<i;y++) ;}}void main(){while(1){yanzou(65,220); //1/2拍中音6yanzou(55,262); //1/2拍高音1yanzou(44,330); //1/2拍高音3yanzou(55,262); //1/2拍高音1yanzou(49,587); //1拍高音2yanzou(55,262); //1/2拍高音1yanzou(58,247); //1/2拍中音7yanzou(44,660); //1拍高音3yanzou(49,587); //1拍高音2yanzou(65,880); //2拍中音6yanzou(55,262); //1/2拍高音1yanzou(44,330); //1/2拍高音3yanzou(37,392); //1/2拍高音5yanzou(37,392); //1/2拍高音5yanzou(65,440); //1拍中音6yanzou(37,392); //1/2拍高音5yanzou(41,349); //1/2拍高音4yanzou(44,2640); //4拍高音3yanzou(41,698); //1拍高音4yanzou(37,784); //1拍高音5yanzou(29,492); //1/2拍高音7yanzou(33,440); //1/2拍高音6yanzou(44,660); //1拍高音3delay(250);yanzou(58,494); //1拍中音7yanzou(65,220); //1/2拍中音6yanzou(44,330); //1/2拍高音3yanzou(49,293); //1/2拍高音2yanzou(41,698); //1拍高音4yanzou(41,698); //1拍高音4yanzou(37,392); //1/2拍高音5yanzou(41,349); //1/2拍高音4yanzou(44,660); //1拍高音3yanzou(49,293); //1/2拍高音2yanzou(55,262); //1/2拍高音1yanzou(44,660); //1拍高音3yanzou(49,587); //1拍高音2yanzou(65,880); //2拍中音6yanzou(65,880); //2拍中音6yanzou(41,698); //1拍高音4yanzou(37,784); //1拍高音5yanzou(29,492); //1/2拍高音7yanzou(33,440); //1/2拍高音6yanzou(44,660); //1拍高音3delay(250);yanzou(58,494); //1拍中音7yanzou(65,220); //1/2拍中音6yanzou(44,330); //1/2拍高音3yanzou(49,293); //1/2拍高音2yanzou(41,698); //1拍高音4yanzou(41,698); //1拍高音4yanzou(37,392); //1/2拍高音5yanzou(41,349); //1/2拍高音4yanzou(44,660); //1拍高音3yanzou(49,293); //1/2拍高音2yanzou(55,262); //1/2拍高音1yanzou(44,660); //1拍高音3yanzou(49,587); //1拍高音2yanzou(65,880); //2拍中音6yanzou(65,880); //2拍中音6delay(5000);}}观察方法一的主函数可以发现，每个语句的形式和实现的功能都是一样的，于是可以想到用数组来进行代码的简化。
