蜂鸣器播放生日快乐歌曲
Arduino控制蜂鸣器播放音乐设计说明书
目录一、新媒体装置艺术1、作品原理介绍 (1)2、作品设计的意义 (1)3、作品的主要内容 (1)4、制作方法和流程 (1)5、成果 (9)6、价值和影响 (9)7、创新点 (10)二、结论8、技术方面 (10)9、艺术方面 (10)10、不足及展望 (11)11、谢辞 (11)设计说明书一、作品原理介绍：能感应到物体靠近并且低于50CM时，蜂鸣器发出音乐，并且小灯泡随着音乐节奏变化。
二、作品设计意义：将它应用到图书馆或者购物的地方，当人们靠近的时间能只能朗读出这一栏或者这一块区域有什么东西，能够更加让人们更快速的找到自己需要的东西，很大程度上节约的时间! 也可以应用到车上，当开车的人快要和前面或者后面的物体撞上的时候，会发出声音来提醒你，从而给生命和财产加上保护套。
三、作品主要内容：1、Arduino控制蜂鸣器播放音乐、小灯泡。
2、小灯泡跟随蜂鸣器的音乐节奏变化。
3、当物体离超声波低于50CM时发出指令，控制蜂鸣器、小灯泡。
四、制作方法和流程：adruino uno一块（其他Arduino板子也可，注意引脚就行），面保线若干条，蜂鸣器或小喇叭一个。
原理：首先讲下简单的乐理知识，知道音乐是怎么演奏出来的自然就可以通过代码来进行编排了。
1.演奏单音符的原理一首音乐由若干音符组成，每一个音符唯一对应一个频率。
如果我们知道了音符相对应的频率，再让 Arduino 按照这个频率输出到蜂鸣器或喇叭，蜂鸣器或喇叭就会发出相应频率下的声音。
Arduino官方网站给出了不同音符对应的不同频率的头文件，具体请见下文介绍。
2.音符演奏的持续时间每个音符都会播放一定的时间，这样才能构成一首优美的曲子，而不是每个音符都播放一样长的时间。
如何确定每个音符演奏的单位时间呢？我们知道，音符节奏分为1拍、1/2拍、1/4拍、1/8拍等等，我们规定一拍音符的时间为1；半拍为0.5；1/4拍为0.25；1/8拍为0.125……，所以我们可以为每个音符赋予这样的拍子播放出来，音乐就成了。

播放生日快乐歌曲
安徽冶金科技职业学院实训报告课题名称播放生日快乐歌系部班级学生姓名指导教师年月日一、播放生日快乐歌的原理：通过80C51乐曲播放电路中，P1.7接发声器SOND，P1.0接启动键<K0>，按一次K0就播放一遍生日快乐歌<fosc=12MHz>；控制输出方波形频率用定时/计数器比延时程序更加准确，根据C音调、半周期和fosc=12MHz条件下选T0定时器方式0计算出来的；播放乐曲，除了控制频率，还有控制时间的问题，用T0方式0控制音频频率，T1方式1控制音符节拍，编制生日快乐歌曲音符序号数组s[26]和生日快乐歌曲音符节拍长度数组L[26]，两数组序号具有对应关系。
例如：播放生日快乐歌第一个音符“5”，1/8拍，取4*50ms=200ms；遇休止符0；停止发音频，但仍当做一个音符，按其节拍长短控制定时时间。
当一个音符播放结束，T1停，转入下一个音符，中间间隔延时10ms。
设T1定时时间:50ms计算T1定时初值：T1（初值）=3CB0H因此：TH1=0x3c，TL1=0xb0三、生日快乐歌曲编程：#include <reg51.h> //包含访问sfr库函数reg51.hsbit K0=P1^0; //定义启动键K0为P1.0sbit SOND=P1^7; //定义发声器SOND为P1.7unsigned char i,j; //定义字符型循环变量i（音符序数）、j（50ms整倍数）unsigned char code th[22]={ //定义音符频率定时数组高8位（12MHz，定时方式0）0,196,202,208,211,216,220,224,226,229,232,233,236,238,240,241,242,244,244,246,2 67,248};unsigned char code tl[22]={ //定义音符频率定时数组低8位（12MHz，定时方式0）0,12,27,21,7,4,16,12,4,12,9,20,2,8,6,2,22,5,26,1,4,3};unsigned char s[26]={ //定义生日快乐歌曲音符序数数组12,12,13,12,15,14,12,12,13,12,16,15,12,12,19,17,15,14,13,0,18,18,17,15,16,15}; unsigned char L[26]={ //定义生日快乐歌曲音符节拍长度数组（50ms整倍数）4,4,8,8,8,16,4,4,8,8,8,16,4,4,8,8,8,8,16,8,4,4,8,8,8,16};void main(){ //主函数unsigned int t; //定义循环变量t（用于音符发声后间隙延时）TMOD=0x10; //T0定时器方式0，T1定时器方式1TH1=0x3c;TL1=0xb0; //置T1初值50msIP=0x02;IE=0x8a; //置T0为高优先级中断，T0、T1开中断while(1){ //无限循环while(K0==1); //等待按K0按下while(K0==0); //等待按K0释放for(i=0;i<26;i++){ //歌曲音符节拍循环if(s[i]==0) {SOND=0; //若歌曲音符序数为0，停止发声TR0=0;} //T0停止运行else {TH0=th[s[i]]; //否则，置T0初值高8位（音符方波半周期）TL0=tl[s[i]]; //置T0初值低8位（音符方波半周期）TR0=1;} //T0运行j=L[i];TR1=1; //置50ms计数器初值，T1运行while(TR1==1); //等待T1停止运行TR0=0;SOND=0; //T0停止运行，停止发声for(t=0;t<2000;t++);}}} //音符间隔延时为10msvoid t0() interrupt 1 { //T0中断函数SOND=~SOND; //输出取反（产音频方波）TH0=th[s[i]]; TL0=tl[s[i]];} //重置T0初值void t1() interrupt 3 { //T1中断函数TH1=0x3c;TL1=0xb0; //重置T1初值50msif((j--)==0) TR1=0;} //若50ms计数器减1为0，T1停止四、播放生日快乐歌的步骤和调试：A.创建keil项目：1)双击桌面keil软件2)打开keil的集成开发环境3)点击菜单栏项目project选新建new project4)选择保存路径，建立项目文件夹，给项目命名并保存。

蜂鸣器唱歌程序
蜂鸣器唱歌----生日快乐下面是我单片机入门的时候写的一个蜂鸣器唱歌的程序，用的是stc89c52的单片机和12MHZ的晶振。
它大致是这样工作的。
我们知道歌曲都是由最基本的音调和节拍组成的。
音调就是该音符的频率，节拍就是该音符持续的时间。
也就是说发出一个最基本的音我们需要两个参数，一个是频率，一个是节拍。
那么在单片机中如何产生这两个参数呢？首先我们需要知道该音符的频率，然后用单片机的I/O口不断地变高变低来产生这个频率。
比如 1 这个音在低音，中音，高音三种情况下会有3种频率，至于到底是哪种音，在歌曲的乐谱中会给出详细的标识。
现在我们假设1 这个音为低音，在d调（什么是d调？看文章尾附录）下频率为293hz,一个周期为T=1/293 s。
那么I/O口被置1和置0的时间各占一半也就是T/2。
然后算出相应的定时器初值，那么单片机就可以发出这个音了。
接下来就是一个音符要唱多久，那就要看这个音符占据多少个节拍了，同样在歌曲的乐谱中会给出详细的标示。
那么一拍是多长呢，下面有说明。
慢节奏一般600ms一拍，快节奏一般400ms一拍。
如果你要知道更准确的节拍时长，只有拿着乐谱去听歌了，记下唱一拍的时间就行了。
我用的是定时器0控制节拍长度，在每个音符开始时开启它，它是10ms 中断一次，并且让里面的计数值增加1。
如果我要唱一拍的话(假设为600ms),那么我只需要判断计数值是否达到60，如果达到那么就停止计时然后跳到下一拍。
以上就是蜂鸣器唱歌的基本原理了，希望能对你有所帮助。

蜡烛播放生日歌的原理
蜡烛播放生日歌的最核心部件是一枚微型芯片,它储存了生日歌的音频文件。
当蜡烛被点燃时,芯片会检测到烛火的高温,然后开始播放存储的生日歌音频。
那么,它是如何检测到烛火温度的呢?蜡烛芯中嵌入了一个微型热敏电阻,它的电阻值会随着温度的升高而增大。
芯片内置了一个简单的电路,通过电阻的大小变化来检测温度。
当烛火温度超过一定值时,电阻值变化明显,芯片就“知道”蜡烛被点燃了。
这与我们小时候使用的体温计原理类似,都是通过物质电阻随温度变化来检测温度。
那么芯片是如何播放储存的音频文件呢?芯片中集成了一个简单的音频解码芯片,以及一个微型的扬声器。
音频解码芯片将数字音频信号转换为模拟音频信号输出到扬声器。
扬声器则将电信号转换为机械振动,产生声音波传播到空气中。
我们就可以听到蜡烛“唱”生日歌了。
整个蜡烛的设计可谓机电结合,将热敏电阻、芯片、扬声器巧妙融合,应用控制论、信号处理等原理,实现了一个多学科交叉的系统。
虽然每个原件都很小巧,但整体协同工作时,就能实现我们想要的“会唱歌”功能。
蜡烛播放生日歌看似神奇,但其内在运作全靠科学原理。
正是电子学、热学、控制论等知识的巧妙应用,造就了这个朴实而富含创意的产品。
它让我们领略科学造福生活的魅力,为我们的生日增添一份小小的仪式感。
我用了大约2500字详细剖析了蜡烛播放生日歌的科学原理。
简单的创意往往最难得,希望这些知识可以启发你生活中的小创新。
如果你还有任何疑问,非常欢迎

伊能静《生日快乐》歌词
多么简单的一句话Happy Birthday
多么平凡的一句话Happy Birthday
从童年到成长人们说过了多少次
在这一瞬间我只想要对你说
拿著送你的礼物Happy Birthday
可以共舞的音乐盒Happy Birthday
从无知到长大不知舞伴换过多少次
在这一瞬间我只希望会是你
送你的音乐盒是去年就买好的
流出的音乐是你我都很熟悉的歌
Happy Birthday to You Happy Birthday to You
我总是站在角落悄悄望著你幻想将礼物送给你你会是什么心情和表情是否欢喜
多么简单的一句话Happy Birthday
多么平凡的一句话Happy Birthday
从童年到成长人们说过了多少次
在这一瞬间我只想要对你说
拿著送你的礼物Happy Birthday
可以共舞的音乐盒Happy Birthday
从无知到长大不知舞伴换过多少次
在这一瞬间我只希望会是你
我总是站在角落悄悄望著你幻想将礼物送给你你会是什么心情和表情是否欢喜
我从不想去真正独自拥有你也知道你从来不在意只想看看你微笑的表情默默是我对你的心情。

常用电子玩具电路实例精选
第一章声光类玩具电路２第一节摇声光圣诞树一、功能概述圣诞树是在庆祝圣诞节时用的一种装饰品，一般用杉、松、柏等塔形常绿树制成，树上挂有花彩、缎带、玩具和贺卡等节庆物品，也有饰以彩灯的，以增加节日气氛。
圣诞节时，许多场所都摆放有各式各样的圣诞树，它不仅为人们营造了浓郁的节日气氛，而且还为人们带来了一份祝福！声光圣诞树能够发出悦耳的《圣诞歌》乐曲，同时伴有红、绿、黄等颜色的彩灯闪亮。
一棵声光圣诞树能为圣诞之夜增添欢快的节日气氛，并为节日的居室增添艳丽的光彩。
二、电路工作原理声光圣诞树的电路包括声响电路和闪光电路两大部分：集成电路陨悦员、压电蜂鸣器月和电阻砸员等构成声响电路；陨悦圆、晶体管灾栽员～灾栽猿，以及发光二极管蕴耘阅员～蕴耘阅员缘等构成闪光电路。
闪光电路又是由功能相同、结构相同的三个相互独立电路部分组成，分别闪烁红、黄、绿三种颜色的光。
电源部分（猿灾）采用两节缘号电池供电。
其电路原理如图员鄄员所示。
电路工作过程如下。
当接通电源开关杂员后，陨悦员供电并且被触发开始工作，输出其事先存储好的音频信号（《圣诞歌》乐曲），驱动压电蜂鸣器月演奏《圣诞歌》乐曲。
与此同时，陨悦圆粤、陨悦圆月、砸圆、砸猿和悦员构成的多谐振荡器开始工作产生猿～源匀扎的脉冲方波，经电阻砸源和三极管灾栽员进行电流放大，控制发光二极管蕴耘阅员～蕴耘阅缘工作。
当脉冲方波处于高电平时，经灾栽员反向在其集电极出现低电平，此时发光二极管蕴耘阅员～蕴耘阅缘处于导通状态而发光；当脉冲方波处于低电平时，经灾栽员反向在其集电极出现高电平，此时发光二极管蕴耘阅员～蕴耘阅缘处于截止状态而不发光。
脉冲方波控制的发光二极管蕴耘阅员～蕴耘阅缘表现为时亮时灭的闪烁效果，其中砸缘为限流电阻。
另外，陨悦圆悦、陨悦圆阅、砸远、砸苑和悦圆构成的多谐振荡器及相应的二极管发光电路，陨悦圆耘、陨悦圆云、砸员园、砸员员和悦猿构成的多谐振荡器及相应的二第一章摇声光类玩具电路３第一节摇声光圣诞树４极管发光电路，二者的工作原理与上述的闪光电路完全相同。
