安卓音乐播放器开发含源代码

基于an droid平台的音乐播放器开发实验报告学生姓名：_______ 温从林 _________________学号: ___________________________________班级：计自1201 _____________第一章引言1.1项目背景当今社会的生活节奏越来越快，人们对手机的要求也越来越高，由于手机市场发展迅速，使得手机操作系统也出现了不同各类，现在的市场上主要有三个手机操作系统，Win dowsmobile，symbia n，以及谷歌的An droid操作系统，其中占有开放源代码优势的An droid系统有最大的发展前景。

那么能否在手机上拥有自己编写的个性音乐播放器呢？能的，谷歌An droid系统就能做到。

本文的音乐播放器就是基于谷歌An droid手机平台的播放器。

An droid :是谷歌于2007年公布的开放式源代码手机系统，它的开放性就优于其它封闭式的手机系统，因此，任何人都可能根据自己的喜好将手机系统中的所有功能重新编写。

这使得越来越多的人关注这个操作系统。

本次作品音乐播放器就是基于An droid平台的。

1.2编写目的现今社会生活紧张，而欣赏音乐是其中最好的舒缓压力的方式之一，本项目的目的是开发一个可以播放主流音乐文件格式的播放器，本设计实现的主要功能是播放Mp3 Wav多种格式的音乐文件，并且能够控制播放，暂停，停止，播放列等基本播放控制功能，界面简明，操作简单。

本项目是一款基于An droid手机平台的音乐播放器，使An droid手机拥有个性的多媒体播放器，使手机显得更生动灵活化，与人们更为接近，让手机主人随时随地处于音乐视频的旋律之中。

使人们的生活更加多样化。

也使设计者更加熟练An droid的技术和其它在市场上的特点。

1.3开发环境Eclipse、An droid SDK 320第二章系统需求分析2.1功能需求（用例图分析）根据项目的目标，我们可获得项目系统的基本需求，以下从不同角度来描述系统的需求，并且使用用例图来描述，系统的功能需求，我们分成四部分来概括，即播放器的基本控制需要，播放列表管理需求，播放器友好性需求和播放器扩展卡需求。

小程序音乐流程

小程序音乐流程小程序音乐流程随着智能手机的普及，人们越来越喜欢在手机上进行各种娱乐活动，其中之一就是听音乐。

小程序音乐流程就是为用户提供了一个方便快捷的音乐播放平台。

首先，用户需要下载安装一个支持小程序的软件，比如微信或者支付宝。

在软件中搜索并打开音乐小程序，进入音乐小程序的首页。

在首页中，用户可以看到推荐的热门歌单、新歌榜、排行榜等内容。

用户可以根据自己的喜好选择一个歌单，点击进入歌单页面。

在歌单页面中，用户可以看到该歌单包含的所有歌曲。

用户可以通过滑动屏幕来浏览歌曲列表，点击某个歌曲可以开始播放。

在播放界面中，用户可以看到歌曲的封面、歌名、歌手等信息。

用户可以通过点击播放按钮来开始播放歌曲，点击暂停按钮来暂停播放。

用户还可以通过滑动进度条来控制歌曲的播放进度。

除了播放音乐，小程序还提供了其他功能。

比如，用户可以选择单曲循环、列表循环或者随机播放歌曲。

用户还可以点击收藏按钮来收藏自己喜欢的歌曲，方便以后再次听到。

用户还可以点击分享按钮将自己喜欢的歌曲分享给朋友，让他们也可以听到这首歌曲。

在小程序中，用户还可以通过搜索来找到自己喜欢的歌曲。

在首页或者歌单页面中，用户可以点击搜索框进入搜索页面。

在搜索页面中，用户可以输入歌曲名、歌手名或者专辑名来搜索相关的歌曲。

搜索结果会显示在页面中，用户可以选择点击某个歌曲来进行播放。

除了搜索功能，小程序还提供了个人中心功能。

用户可以点击个人中心按钮进入个人中心页面，在该页面中可以看到自己的收藏歌曲、最近播放的歌曲等。

用户还可以点击设置按钮来进行个人设置，比如修改昵称、更换头像等。

总的来说，小程序音乐流程为用户提供了一个方便快捷的音乐播放平台。

用户可以通过小程序来搜索、播放自己喜欢的歌曲，并可以进行个人设置和收藏分享等操作。

小程序音乐流程的出现，方便了用户的音乐娱乐活动，提高了用户体验。

C#编的音乐播放器

C#音乐播放器设计一、音乐播放器的最终效果1. 整个播放器的主体最终效果如下：2. 经典模式如下：3. 音乐播放器设计已实现的基本功能：播放、暂停、播放列表、打开音乐文件、删除歌曲、添加歌曲、下一首、上一首、播放模式（顺序、循环、单曲循环、随机）、窗体最顶、经典模式、音量调节、歌曲播放进度控制、歌词同步、保存上次播放状态等等。

二、设计全部源代码1.主窗体(Form1)代码如下：using System;using System.Collections.Generic; using ponentModel; using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms; using

单片机音乐播放器程序设计(DOC)

实验报告 51 单片机设计音乐播放器随着科技的发展，音乐播放功能随处都会用到，如，在开发儿童智力的玩具中，等等。

目前单片机以其体积小、价格低、编程灵活等特点在这一领域独领风骚。

、系统功能要求： 1、具有自动循环播放所有乐曲功能。

2、具有单独选择某首乐曲循环播放功能。

3、具有顺序查找乐曲循环播放功能。

4、具有停止播放功能。

二、系统整体方案提示：利用AT89S52产生乐曲音符，再把乐普翻译成计算机音乐语言，由单片机进行信息处理，在经过信号放大，由喇叭放出乐曲声。

由于音符和节拍是由计算机产生的，所以发音音符和节拍准确。

单独选择某首乐曲循环播放：按下 K4~K7键即可实现。

系统整体方案框图如下：利用 AT89C51产生乐曲音符，再把乐普翻译成绩算计音乐语言，由单片机进行信息处理，在经过信号放大，由喇叭放出乐曲声。

由于音符和节拍是由计算机产生的，所以发音音符和节拍准确。

整体框图如图图一所示。

1、循环播放：按下 K1 键即可实现。

2、顺序查找乐曲循环播放：按下 K2键即可实现。

3、停止播放：按下K3键即可实现。

4、三、硬件系统原理图: 硬件系统原理图如下页图:1）单片机：选择 AT89S52,由于AT89S52是一个低电压，高性能 CMOS 位单片机，内含4k bytes 的可反复擦鞋的制度程序存储器（PERO ）和128bytes 的随机存取数据存储器（RAM ，器件采用ATME 公司的高密度、非易失性存储技术生产，兼容标准MC — 51指令系统，片内置通用8位中央处理器和Flash 存储单元，内置功能强大的微型计算机 AT89S52提供了高性价比的解决方案。

其内部有足够本系统对存储器的要求，不用外扩。

2）按键控制电路：如图由P1 口作为输入，构成矩阵式按键接口方式。

3）输出控制：此部分的放大电路简单容易实现。

主要采用了一个小功率PNP 型硅管9012,利用“分压偏置式工作点稳定直流通路”，达到了对静态工作点的稳定。

基于QT的音乐播放器编程(实现最基本的功能)

第一节实现基本功能说明：源代码我已经上传到CSDN网站，请大家到网站搜索“基于QT的音乐播放器源代码及详细教程”下载。

1.新建工程，基类选择Qwidget。

双击打开界面文件，在界面文件中创建label显示时间、若干个toolbutton按钮和一个listWidget列表显示歌曲列表。

点击“文件”->“新建”创建QT资源文件，在工程目录下建文件夹“images”，双击QT资源文件添加前缀“/”，再添加图标文件。

2.单击上一曲按钮，在属性栏设置标题tooltip和图标icon：界面如下：3.右键几个按钮，转入槽函数，列表和歌词的信号选择clicked（bool）。

4.工程文件中添加语句QT+=phonon对音乐播放器进行设计，主要用到模块中的MediaObject（管理媒体源）AudioOutput（连接物理设备）SeekSlider（实现进度条）QList（实现播放列表）大概地说，Phonon的工作机制是使用MediaObject来管理MediaSource即源文件，通过Path连接到AudioOutput，最后是由AudioOutput5.修改widget.h头文件在widget.h头文件添加语句：#include<phonon>在头文件声明变量：private:Phonon::MediaObject*audio;//QAction*stop;QAction*open;QAction*sound;QAction*exit;QAction*remove;头文件声明函数：public:void creatActions();//创建动作6.修改widget.cpp文件构造函数添加：this->setWindowTitle(tr("音乐播放器"));//设置标题/**初始化媒体**/audio=new Phonon::MediaObject();//媒体对象audio->setTickInterval(1);audioOutput=new Phonon::AudioOutput(Phonon::VideoCategory);//音频输出Phonon::createPath(audio,audioOutput);//连接媒体对象与音频输出musicInformationMediaObject=new Phonon::MediaObject(this);//音乐信息对象volumeSlider=new Phonon::VolumeSlider(audioOutput,this);//音量滑动条volumeSlider->move(190,100);volumeSlider->resize(50,20);volumeSlider->setStyleSheet("background-color:rgb(255,255,255,100)"); volumeSlider->setFixedWidth(100);//固定音量条大小seekSlider=new Phonon::SeekSlider(audio,this);//进度滑动条seekSlider->move(10,35);seekSlider->resize(170,20);seekSlider->setStyleSheet("background-color:rgb(255,255,255,100)");creatActions();函数定义：//播放/暂停void Widget::on_toolButton_playpause_clicked(){if(sourceList.isEmpty()){return;}audio->setQueue(sourceList);//if{}}//{audio->stop();}void Widget::on_toolButton_open_clicked(){QStringList files=QFileDialog::getOpenFileNames(this,tr("SelecFilestoplay"));//使用QFileDialog的getOpenFileNames方法获取若干个音乐文件，QString file;foreach(file,files)//使用Qt中的foreach遍历每个选中的文件，将其添加到播放列表中。

单片机蜂鸣器音乐代码

单片机蜂鸣器音乐代码在单片机的应用中，蜂鸣器是一个常用的音频输出设备。

它可以通过产生不同频率的声音来实现音乐播放、提醒和警报等功能。

本文将介绍如何使用单片机控制蜂鸣器播放音乐，并提供一个简单的音乐代码示例。

首先，让我们了解一下单片机蜂鸣器的工作原理。

蜂鸣器实际上是一个压电陶瓷元件，当电压作用于其上时，它会振动产生声音。

为了产生不同的音调，我们需要控制蜂鸣器的频率和占空比。

单片机通过IO口与蜂鸣器连接，并使用定时器来产生所需的频率。

具体的代码实现将依赖于使用的单片机型号和开发环境。

在这里，我们将以C语言为例，并基于51单片机进行说明。

以下是一个简单的单片机蜂鸣器音乐代码示例，演奏的是《欢乐颂》的前几个音符：```c#include <reg52.h>// 定义各个音符的频率#define C4 4778#define D4 4257#define E4 3792#define F4 3579#define G4 3189#define A4 2841#define B4 2531#define C5 2388// 延时函数void delay(unsigned int count){while(count--);}// 发声函数void beep(unsigned int frequency, unsigned int duration) {unsigned int i;unsigned long time;time = 11059200 / frequency; time >>= 1;for(i = 0; i < duration; i++) {P1 = 0x08;delay(time);P1 = 0x00;delay(time);}}// 主函数void main(){// 设置定时器TMOD = 0x01;TH0 = (65536 - 50000) / 256; TL0 = (65536 - 50000) % 256; TR0 = 1;// 播放音乐beep(C4, 100);beep(D4, 100);beep(E4, 100);beep(F4, 100);beep(G4, 100);beep(A4, 100);beep(B4, 100);beep(C5, 100);while(1);}```以上代码中，我们首先定义了各个音符的频率，这些频率是通过实验测量得到的，具体数值可能因蜂鸣器型号、电源电压等因素而略有差异。

控制台C语言编写音乐播放器主要功能

控制台C语言编写音乐播放器主要功能音乐播放器是一种可以播放音乐文件的应用程序，具有多种功能来帮助用户管理和播放音乐。

下面是控制台C语言编写音乐播放器的主要功能：1.音乐：用户可以通过输入歌曲名或艺术家来他们想要播放的音乐。

功能也可以根据关键词进行过滤和排序。

2.音乐播放：一旦用户找到他们想要听的歌曲，他们可以选择播放它。

音乐播放器应该能够打开并解码音乐文件，然后通过音频设备播放音乐。

4.歌曲信息显示：在播放音乐的同时，音乐播放器应该显示歌曲的相关信息，如歌曲名、艺术家、专辑名、歌词等。

这些信息可以从音乐文件的元数据中获取。

5.音乐控制：音乐播放器应该具有基本的音乐控制功能，如播放、暂停、停止、上一首、下一首等。

用户可以通过命令来控制音乐的播放状态。

6.音量控制：用户可以通过增加或减少音量来调整音乐的音量。

音乐播放器应该能够调整音频设备的输出音量。

7.重复和随机播放：用户可以选择歌曲的播放模式，如顺序播放、循环播放、随机播放等。

音乐播放器应该能够根据用户的选择来调整播放模式。

9.用户界面：音乐播放器应该有一个简洁而直观的用户界面，允许用户轻松地浏览、和管理自己的音乐。

用户界面可以使用控制台界面或基于文本的界面。

10.错误处理：音乐播放器应该能够处理各种错误情况，如无效的输入、文件不存在、解码错误等。

它应该能够向用户显示有关错误的信息，并采取适当的措施来避免应用程序崩溃。

11.文件格式支持：音乐播放器应该支持多种常见的音乐文件格式，如MP3、WAV、FLAC等。

它应该能够根据文件格式选择合适的解码器。

12.常规设置：音乐播放器应该具有一些常规设置，如默认音量、默认播放模式、快捷键等。

用户可以根据自己的需求来调整这些设置。

以上是控制台C语言编写音乐播放器的主要功能。

根据以上功能，你可以开始设计和编写一个简单的音乐播放器应用程序。

当然，你可以根据个人需求和编程能力来扩展和优化这些功能。

用C++编写音乐播放器

编写 CMyplayerDlg::Onplay()的代码，播放选中的音乐， void CMyplayerDlg::Onplay() {
// TODO: Add your control notification handler code here this->m_multimedia.SetCommand("Play"); } 运行程序，便可对选中的音乐进行播放。编写 CMyplayerDlg::Onpause()的代码，暂停播放音乐 void CMyplayerDlg::Onpause() { // TODO: Add your control notification handler code here this->m_multimedia.SetCommand("Pause"); } 编写 CMyplayerDlg::Onclose()的代码，关闭音乐 void CMyplayerDlg::Onclose() { // TODO: Add your control notification handler code here this->m_multimedia.SetCommand("Close"); this->m_pause.EnableWindow(FALSE); this->m_play.EnableWindow(FALSE); this->m_next.EnableWindow(FALSE); this->m_circle.EnableWindow(FALSE); this->m_close.EnableWindow(FALSE); } 编写 CMyplayerDlg::Onnext()的代码，实现选择下一首音乐 void CMyplayerDlg::Onnext() { // TODO: Add your control notification handler code here this->m_multimedia.SetCommand("Next"); Onopen(); this->m_multimedia.SetCommand("Play"); } 编写 CMyplayerDlg::Oncircle() 的代码，实现循环播放音乐 void CMyplayerDlg::Oncircle() { // TODO: Add your control notification handler code here int i; for(i=0;i<50;i++) { this->m_multimedia.SetCommand("Prev"); this->m_multimedia.SetCommand("Play");} } 最后，程序运行结果的界面如下：

微信小程序播放背景音乐的实例代码

微信⼩程序播放背景⾳乐的实例代码⽬录1.实现效果2.实现原理3.实现代码1.实现效果2.实现原理1、wx.getBackgroundAudioManager ：获取全局唯⼀的背景⾳频管理器。

⼩程序切⼊后台，如果⾳频处于播放状态，可以继续播放。

但是后台状态不能通过调⽤API操纵⾳频的播放状态。

从微信客户端6.7.2版本开始，若需要在⼩程序切后台后继续播放⾳频，需要在 app.json 中配置 requiredBackgroundModes 属性。

开发版和体验版上可以直接⽣效，正式版还需通过审核。

2、onUnload和onHide事件中暂停⾳乐的播放。

3、onShow中调⽤播放事件4、在播放结束的事件中，再次播放，以达到循环播放的效果。

3.实现代码<image src="{{checked?'../img/stop.png':'../img/play.png'}}" class="music {{!checked && 'circle'}}" catchtap="checkMusic"></image> <view catchtap="toNext" class="btn"> 去下⼀个页⾯</view>page {background-color: aliceblue;}.music {width: 86rpx;height: 86rpx;position: absolute;top: 108rpx;right: 10rpx;z-index: 99;}.circle {animation: cirlce 4s linear infinite;}@keyframes cirlce {0% {transform: rotate(0deg);}100% {transform: rotate(359deg);}}.btn {margin: 550rpx auto 0;width: 625rpx;height: 80rpx;background: linear-gradient(90deg, #dd8449 0%, #e28e74 52%, #dbb290 100%);border-radius: 6rpx;font-size: 30rpx;color: #fff;line-height: 80rpx;text-align: center;position: relative;overflow: hidden;}.btn:after {content: "";background: #999;position: absolute;width: 750rpx;height: 750rpx;left: calc(50% - 375rpx);top: calc(50% - 375rpx);opacity: 0;margin: auto;border-radius: 50%;transform: scale(1);transition: all 0.4s ease-in-out;}// pages/effects/audioCust/index.jsPage({data: {checked: false,},onShow: function () {this.player(wx.getBackgroundAudioManager())},checkMusic() {console.log(11)this.setData({checked: !this.data.checked})if (this.data.checked) {wx.getBackgroundAudioManager().pause();} else {this.player(wx.getBackgroundAudioManager())}},player(e) {e.title = '苏苏的⾳乐'e.src = "/song/media/outer/url?id=36587407.mp3"//⾳乐播放结束后继续播放此⾳乐，循环不停的播放e.onEnded(() => {this.player(wx.getBackgroundAudioManager())})},// 页⾯卸载时候暂停播放（不加页⾯将⼀直播放）onUnload: function () {wx.getBackgroundAudioManager().stop();},// ⼩程序隐藏时候暂停播放（不加页⾯将⼀直播放）onHide() {wx.getBackgroundAudioManager().stop();},toNext() {wx.navigateTo({url: '/pages/jsCase/draw/index',})}})到此这篇关于微信⼩程序播放背景⾳乐的⽂章就介绍到这了,更多相关⼩程序播放背景⾳乐内容请搜索以前的⽂章或继续浏览下⾯的相关⽂章希望⼤家以后多多⽀持！。

一个音乐播放程序的编写
基础知识: 乐音的音调是由频率决定音符是构成一首曲子的基本元素我们的目的是产生——一组固定的频率来表示音符
频率和音符的ቤተ መጻሕፍቲ ባይዱ应关系
2 3 4 5 6 音符 1 频率 131 147 165 175 196 220 2 3 4 5 6 音符 1 频率 294 330 349 392 440 492 7 262 7 523
2 3 4 5 6 7 音符 1 频率 587 659 697 783 879 983 1046
节拍的产生
就是延时一般是每秒 96拍在一个节拍里让单片机保持输出一个固定频率
硬件电路
软件规划
4首曲子循环播放定时器1产生频率定时器2产生节拍主程序完成曲目的调用
主程序设计
main() { InitDevice(); PlaySong(Pass); while(1) { PlaySong(JingleBells); PlaySong(Pass); PlaySong(SOS); PlaySong(Pass); PlaySong(Yesterday); PlaySong(Pass); PlaySong(BeatIt); PlaySong(Pass); } }
