单片机蜂鸣器编程技巧

单片机蜂鸣器编程技巧1.音乐节奏控制：在编写程序时，可以使用定时器来控制蜂鸣器的音符持续时间。

通过调整定时器的参数值，可以实现不同音长的音符，从而控制节奏感。

2.音符频率控制：不同音符具有不同的频率，可以根据乐谱中各个音符的频率，将其对应的频率值存储在一个数组中。

通过控制蜂鸣器输出的频率，可以实现不同音高的音符。

3.延时函数：在单片机编程中，经常需要使用延时函数来控制时间间隔。

在输出音乐时，可以通过延时函数控制每个音符的持续时间。

通过调整延时函数的参数值，可以实现不同音符间的时间间隔，从而实现更好听的音乐效果。

4.音乐合奏：在编写程序时，可以将不同乐器的音符同时输出到不同的蜂鸣器上，从而实现多个乐器的合奏效果。

通过合理地组合不同乐器的频率和节奏，可以编写出更丰富的音乐作品。

5.音乐循环播放：通过编写循环结构，可以实现音乐循环播放的效果。

通过精确地确定循环次数，可以实现指定音乐节拍的循环播放效果。

6.音乐速度调节：通过调整延时函数的参数值，可以控制音乐的播放速度。

加快延时时间可以使音乐播放加速，减慢延时时间可以使音乐放慢。

7.音乐音量控制：通过控制蜂鸣器输出的PWM信号的占空比，可以实现音乐的音量控制。

调整PWM信号占空比的大小，可以改变音量的大小。

8.音乐渐变效果：在编写程序时，可以使用渐变效果来实现音乐的过渡效果。

通过逐渐增加或减小频率和音量，可以实现音乐渐变的效果，使音乐更加流畅自然。

9.使用音乐库：在单片机编程中，有一些常用的音乐库可以使用。

通过引用这些音乐库，可以简化音乐的编写过程，提高编程效率。

10.节奏变化：在编写程序时，可以尝试在音乐的不同位置加入一些节奏变化，使音乐更加有层次感。

例如，在特定位置加入加速、变慢、停顿等效果。

总结：以上是一些常用的单片机蜂鸣器编程技巧。

通过合理运用这些技巧，可以编写出更多样化、更复杂的音乐效果。

当然，这只是冰山一角，还有很多其他的编程技巧可以尝试，通过对单片机蜂鸣器的深入研究和实践，我们可以更好地掌握这些技巧，创作出独特的音乐作品。

用单片机驱动蜂鸣器的演奏说明

用单片机驱动蜂鸣器演奏的方法说明音的产生是由于物体的振动，通过单片机供电来控制蜂鸣器振动来发声。

单片机IO 口通过高低电平快速切换形成频率可以驱动蜂鸣器发音。

这样蜂鸣器就会以不同的音调“鸣响”。

这里主要理解“音调”和“节拍”两个概念。

音调表示一个音的频率是多少。

即就是音的高低。

在钢琴上，中央C 所在音阶的A ，（C D E F G A B ）A 的频率作为基准频率，440Hz 。

同时，需要知道如果f2 = f1*2，则称f2是f1的高八度，即f2和f1的音名相同，高度高了一个音阶。

按照钢琴12平均律，将一个音阶的音均分成12份，那么每一个对应的音都可以计算出确定的频率了。

注意！八度音指频率加倍，将八度音分为12等份，是分为12个等比级数。

f2=f1*2，且f1*12q =f2，可以计算，这个等比数列的比值是q=122=1212=1.05946.为了实现不同音的频率，需要单片机通过定时器不停的产生中断，实现管脚电平反转，来产生相应频率。

这时定时器装载初始值如何计算呢？以标准A 为例，A （f=440Hz)，T=1/f=1/440=0.00227273s=2272.73us ，即单片机管脚要输出周期为2272.73us 或者f=440Hz 的方波。

通过单片机定时中断来实现反转的话，考虑单片机定时器装载数值为多少才能形成2272us 的定时中断呢？假设系统时钟8MHz ，则x/8MHz=2272.73us ，x = 18181.1818... x 取整数18181，即定时器应装载18181，才能产生440Hz 的频率。

单片机课程设计报告利用蜂鸣器播放音乐

课程设计：嵌入式系统应用题目名称：利用蜂鸣器实现音乐播放功能姓名：学号：班级：完成时间：1设计的任务设计内容：动手焊接一个51单片机设计目标：利用单片机上的蜂鸣器实现音乐播放功能2设计的过程基本结构在本次的试验中采用了STC89C52RC单片机,STC89C52RC单片机是宏晶科技推出的新一代高速/低功耗/超强抗干扰的单片机,指令代码完全兼容传统8051单片机,12时钟/机器周期,工作电压：～5V单片机/～3V单片机,工作频率范围：0～40MHz,相当于普通8051的0～80MHz,实际工作频率可达48MHz,用户应用程序空间为8K字节;STC89C52RC引脚图STC89C52RC单片机的工作模式：（1）典型功耗<μA,可由外部中断唤醒,中断返回后,继续执行原程序（2）空闲模式：典型功耗2mA（3）正常工作模式：典型功耗4Ma～7mA4唤醒,适用于水表、气表等电池供电系统及便携设备2.蜂鸣器及其工作原理：蜂鸣器按其结构分主要分为压电式蜂鸣器和电磁式蜂鸣器两种类型;电磁式蜂鸣器由振荡器、电磁线圈、磁铁、振动膜片及外壳等组成;接通电源后,振荡器产生的音频信号电流通过电磁线圈,使电磁线圈产生磁场,振动膜片在电磁线圈和磁铁的相互作用下,周期性地振动发声;本实验采用的是电磁式蜂鸣器;蜂鸣器按其是否带有信号源又分为有源和无源两种类型;有源蜂鸣器只需要在其供电端加上额定直流电压,其内部的震荡器就可以产生固定频率的信号,驱动蜂鸣器发出声音;无源蜂鸣器可以理解成与喇叭一样,需要在其供电端上加上高低不断变化的电信号才可以驱动发出声音;本实验采用的是有源蜂鸣器;蜂鸣器与单片机连接电路图软件设计过程1.蜂鸣器发声原理本实验由于采用有源蜂鸣器,只需将引脚端口P3^4清零,蜂鸣器即可发声；P3^4置位,蜂鸣器停止发声;采用置1置0的方法只能使蜂鸣器发声或停止发声,想要使蜂鸣器发出声音,必须对蜂鸣器发出声音的音频和节拍进行控制;音乐基础音调：不同音高的乐音是用C、D、E、F、G、A、B来表示,这7个字母就是音乐的音名,它们一般依次唱成DO、RE、MI、FA、SO、LA、SI,即唱成简谱的1、2、3、4、5、6、7,相当于汉字“多来米发梭拉西”的读音,这是唱曲时乐音的发音,所以叫“音调”,即Tone;把C、D、E、F、G、A、B这一组音的距离分成12个等份,每一个等份叫一个“半音”;两个音之间的距离有两个“半音”,就叫“全音”;在钢琴等键盘乐器上,C–D、D–E、F–G、G–A、A–B两音之间隔着一个黑键,他们之间的距离就是全音；E–F、B–C两音之间没有黑键相隔,它们之间的距离就是半音;通常唱成1、2、3、4、5、6、7的音叫自然音,那些在它们的左上角加上﹟号或者b号的叫变化音;﹟叫升记号,表示把音在原来的基础上升高半音,b叫降记音,表示在原来的基础上降低半音;例如高音DO的频率1046Hz刚好是中音DO的频率523Hz的一倍,中音DO的频率523Hz刚好是低音DO频率266Hz的一倍；同样的,高音RE 的频率1175Hz刚好是中音RE的频率587Hz的一倍,中音RE的频率587Hz 刚好是低音RE频率294Hz的一倍;节拍：节拍是让音乐具有旋律固定的律动,而且可以调节各个音的快满度;“节拍”,即Beat,简单说就是打拍子,就像我们听音乐不自主的随之拍手或跺脚;若1拍实,则1/4拍为;至于1拍多少s,并没有严格规定,就像人的心跳一样,大部分人的心跳是每分钟72下,有些人快一点,有些人慢一点,只要听的悦耳就好;音持续时间的长短即时值,一般用拍数表示;休止符表示暂停发音;1）控制发声频率要产生音频脉冲,只要算出某一音频的周期1/频率,然后将此周期除以2,即为半周期的时间;利用定时器计时这半个周期时间,每当计时到后就将输出脉冲的I/O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 脚上得到此频率的脉冲;利用STC89C52RC的内部定时器使其工作在计数器模式MODE1下,改变计数值TH0及TL0从而产生不同频率;此外结束符和休止符可以分别用代码00H和FFH来表示,若查表结果为0x00,则表示曲子终了；若查表结果为0xff,则产生相应的停顿效果;以标准音高A为例,A的频率是440Hz,周期T=1/440=2272us;在占空比为50%的情况下,导通时间=断开时间=半周期t=2272us/2=1136us,利用P3^4端口的位操作,经过不断地反相变换即可得到标准音高A的音频脉冲;端口导通时间与断开时的时间利用定时器实现;具体的方法是将单片机定时器的中断触发时间设为半周期t,这样每隔半周期端口反相,输出连续的对应音高的频率;设晶振的频率为f0,中断触发时间半周期为t,定时器工作在模式1时计数器的初值为THL,高8位为THL,低8位为TL;时钟周期即为1/f0,定时器每一次累加用去一个机器周期,一个机器周期包含12个时钟周期,即定时器每次加一所用时间是12/f0;定时器在模式1下计时采用16位数,最大计数为2^16-165535,再次加一65536溢出触发中断;根据以上分析可得如下关系：音频对应定时器初值的高8位TH=THL/2^8=65536-tf/12/256;音频对应定时器初值的低8位TL=THL%2^8=65536-tf/12%256;附：八度12音阶定时器初值表只含自然音低音音名频率Hz 晶振12MHz 晶振中音音名频率Hz 晶振12MHz 晶振高音音名频率Hz 晶振12MHz 晶振 Do 262 0xF885 0xF91B Do 523 0xFC43 0xFC8E Do 1046 0xFE21 0xFE47 Re 294 0xF95A 0xF9DF Re 587 0xFCAD 0xFCED Re 1175 0xFE56 0xFE76 Mi 330 0xFA13 0xFA8A Mi 659 0xFD0A 0xFD43 Mi 1318 0xFE85 0xFEA1 Fa 349 0xFA68 0xFAD8 Fa 698 0xFD34 0xFD6A Fa 1397 0xFE9A 0xFEC7 So 392 0xFB04 0xFB68 So 784 0xFD82 0xFDB3 So 1568 0xFEC1 0xFED9 La 440 0xFB90 0xFBE9 La 880 0xFDC8 0xFDF3 La 1760 0xFEE4 0xFEF9 Si4940xFC0C0xFC5BSi9880xFE060xFE2DSi19760xFF030xFF162控制发声节拍每个音符的节拍可通过延时一定的时间来实现,在具体实现时需要有一个基本的带参延时程序,用于主函数根据不同的音符调用不同的时延;若以十六分之一音符的时长为基本延时时间,则十六分音符只需调用一次延时程序,八分音符则需调用两次延时程序,以此类推;3）简谱及其编码用数字1至7表示;这7个数字就等于的;如果是C 大调,加上音名,就会是这样：八度如果是高一个八度,就会在数字上方加上一点;如果是低一个八度,就会数字下方加上一点;在中间的那一个就什么也不用加;如果要再高一个八度,就在上方垂直加上两点如：；要再低一个八度,就在下方垂直加上两点如：,如此类推;见下表所示：大调 ... ... 小调......音长通常只有数字的是;数字下加一条横线,就可令四分音符的长度减半,即成为；两条横线可令八分音符的长度减半,即成为,余此类推；简单来説,下音阶CDEFGAB唱名 do re mi fa so la si数字 1 2 3 4 5 6 7加横綫数目与五綫谱的符尾数目相对应;数字后方的横线延长音符,每加一条横线延长一个的长度;正如五綫谱的附点一样,数字后方加一点会将音符长度增加一半;休止符休止符用“0”来表示;比四分休止符长,就只需在每一个四分休止符再多加一个“0”,不需在后方加上横线;若整个小节均是休止状态的话,就在每个四分音符加一个“0”,就像是3拍4就写成“|000|”,而4拍4就写成“|0000|”;无音高音符就像敲击乐的乐器那样是没有音高的,这时,简谱就需要用“X”或“x”表达;例如拍手时,简谱上就需如此表达：小节线正如五綫谱一样,小节与小节之间以纵綫称分隔,乐曲终止以一粗一细的直綫表示但是一般不分粗细；重复乐段以纵綫后两点表示开始,纵綫前两点表示终止;拍号的表达方式为：“2/4”、“3/4”、“4/4”、“6/8”等等;拍号一般都是置于的后方;变调与调号表示有两种方法：可以直接写“C调”,“C小调”或“Key:C”,“Key:Cm”;亦可写清楚主音代表哪一个音,例如1=C,就是C大调大调以1为主音;6=C就是C小调小调以6为主音;2=D就是D多利安调以2为主音;五线谱有,简谱同样有升降号;在简谱中,若需表达升降号,就把符号加在数字1至7的前方,让该音升高或降低;若要把升降号加在调号跟CDEFGAB七个字母,就须加在它们的后方;在五綫谱中,C小调要把B-E-A三个音降低半音;所以表达它的和声小调时,就会把一个放在B前面;简谱就一定得写 5,因为5不能下降;延音线、圆滑线与其他音乐符号简谱Tie跟slur都是跟五线谱相同,一定得置在数字上方;表达staccato时需要特别小心,因为很容易会跟低八度的那一点混淆,因此在表达跳音时把那一点写得粗点及低点;简谱编码将简谱中的每个音符进行编码,每个音符用一个unsignedchar字符类型表示,简谱可用一个unsignedchar字符数组表示;字符的前四位表示音频,可以表示0-f共十六个音符;本实验中采用了中音区和高音区;中音do-si分别编码为1~7,高音do-si分别编码为8~E,停顿编为0;字符的后四位表示节拍,节拍以十六分音符为单位在本程序中为165ms,一拍即四分音符等于4个十六分音符,编为4,其它的播放时间以此类推;以0xff作为曲谱的结束标志;程序从数组中取出一个数,然后分离出高4位得到音调,将值赋给定时器0,得到音调；接着分离出该数的低4位,得到节拍;本实验中播放音乐使用简谱如下：将其编码成：ucharcodezbjbxf={0x64,0xA3,0xC1,0xA2,0x62,0x84,0x61,0x81,0x61,0xA4,0xA1,0x91,0xA1,0x81,0 x64,0xA3,0xC1,0xD2,0xD2,0xD2,0xA2,0xC4,0xA1,0xC1,0xA1,0xC1,0xD2,0xD2,0x D2,0xA2,0xC4,0xC2,0x62,0xC2,0x62,0xA2,0xA2,0x84,0x94,0x94,0x92,0x81,0x9 1,0xA2,0xC2,0xD4,0xE4,0xA4,0xE4,0xA2,0xE2,0xA2,0xE2,0xA2,0xA2,0x84,0x94 ,0x94,0x92,0x81,0x91,0xA2,0xC2,0xD8};程序流图及说明主程序流程图程序代码：include<> defineucharunsignedchardefineuintunsignedintsbitfm=P3^4;算机与单片机的连接不上问题计算机与单片机的连接需要在电脑端安装相应的USB转串的驱动,由于我组没有使用实验室windowsxp系统,而使用的是个人计算机windows7系统,所以需要针对win7的驱动;后来联网搜索下载相应的驱动之后解决了这一问题;2.如何使蜂鸣器发出声音而非Be-Be声为了解决这个问题,我们深入研究了蜂鸣器发声原理与乐谱相关的知识;通过学习相关知识发现,不同的音符对应不同的音高,音高取决于发声频率;所以可以通过构造不同频率的方波来使蜂鸣器发出不同频率的声音,具体实现时利用定时器计时,定时器每一次累加消耗一个机器周期,即12个时钟周期;本实验采用晶振频率为12MHz,即定时器每一次累加消耗1us,通过设置定时器初值设定蜂鸣器取法的时间间隔,从而产生相应的音频;每个音符不但有频率属性,还有节拍属性;对不同节拍的控制可以采用延迟一定的时间来得到; 5总结在本次课程设计中,我们进一步加深了对小型嵌入式系统的认识;实验初期单片机需要自己焊接,通过亲手焊接电路板,了解了如何将实验原理图转化为具体的硬件实物连接;通过使用TN单片机开发板和STC89C52RC系统,对单片机应用开发有了初步的熟悉;在实验的过程中,使用到了C51的编译环境KeilC和单片机通讯程序STC_ISP,两者是单片机开发所不可缺少的工具;在具体实施的过程中,通过一一解决遇到的问题,增强了动手实践能力;。

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。

单片机课程设计报告利用蜂鸣器播放音乐样本

课程设计: 电子设计题目名称: 音乐流水灯姓名: 戴锦超学号: 08123447班级: 信科12-3班完成时间: 10月23日1设计的任务设计内容: 动手焊接一个51单片机设计目标: 利用单片机上的蜂鸣器以及二极管实现音乐播放以及根据音乐的节奏而规律性闪亮的二极管。

而且经过程序调节音乐节奏的快慢。

2 设计的过程2.1 基本结构1.STC89C52RC在本次的试验中采用了STC89C52RC单片机, STC89C52RC 单片机是宏晶科技推出的新一代高速/低功耗/超强抗干扰的单片机, 指令代码完全兼容传统8051单片机, 12时钟/机器周期, 工作电压: 5.5V～3.3V( 5V单片机) /3.8V～2.0V( 3V单片机) , 工作频率范围: 0～40MHz, 相当于普通8051的0～80MHz, 实际工作频率可达48MHz, 用户应用程序空间为8K字节。

( STC89C52RC引脚图)STC89C52RC单片机的工作模式:（1）典型功耗<0.1μA,可由外部中断唤醒, 中断返回后, 继续执行原程序（2）空闲模式: 典型功耗2mA（3）正常工作模式: 典型功耗4Ma～7mA( 4) 唤醒, 适用于水表、气表等电池供电系统及便携设备2.蜂鸣器及其工作原理:蜂鸣器按其结构分主要分为压电式蜂鸣器和电磁式蜂鸣器两种类型。

电磁式蜂鸣器由振荡器、电磁线圈、磁铁、振动膜片及外壳等组成。

接通电源后, 振荡器产生的音频信号电流经过电磁线圈, 使电磁线圈产生磁场, 振动膜片在电磁线圈和磁铁的相互作用下, 周期性地振动发声。

本实验采用的是电磁式蜂鸣器。

蜂鸣器按其是否带有信号源又分为有源和无源两种类型。

有源蜂鸣器只需要在其供电端加上额定直流电压, 其内部的震荡器就能够产生固定频率的信号, 驱动蜂鸣器发出声音。

无源蜂鸣器能够理解成与喇叭一样, 需要在其供电端上加上高低不断变化的电信号才能够驱动发出声音。

本实验采用的是有源蜂鸣器。
