La lecture audio simple basée sur html5 est assez bonne et peut être utilisée comme référence. Le code est ci-dessous

$(function() {
	getSong();
})

//获取歌曲链接并插入dom中
function getSong() { 
	var audio = document.getElementById("audio");
	audio.src = "http://frontman.qiniudn.com/songnotime.mp3";
	audio.loop = true; //歌曲循环
	playCotrol(); //播放控制函数

}

//点击播放/暂停
function clicks() {
	var audio = document.getElementById("audio");
	$("#control").click(function() {
		if ($("#control").hasClass("play")) {
			$("#control").addClass("pause").removeClass("play");
			audio.play();//开始播放
			dragMove();//并且滚动条开始滑动
			$("#control").html("暂停播放");
		} else {
			$("#control").addClass("play").removeClass("pause");

			audio.pause();
		}
	})

//播放时间
function timeChange(time, timePlace) {//默认获取的时间是时间戳改成我们常见的时间格式
	var timePlace = document.getElementById(timePlace);
	//分钟
	var minute = time / 60;
	var minutes = parseInt(minute);
	if (minutes < 10) {

	//秒
	var second = time % 60;

	timePlace.innerHTML = allTime;
}

//播放事件监听
function playCotrol() {

		function() {
			$("#control").addClass("play").removeClass("color_gray");

			var allTime = audio.duration;

//进度条
这里我用的是事件实现进度拖动 如果不太熟悉touch的可以看下我之前写的一个小demo http://www.cnblogs.com/leinov/p/3701951.html
 var startX, x, aboveX = 0; //触摸时的坐标 //滑动的距离  //设一个全局变量记录上一次内部块滑动的位置 

//1拖动监听touch事件
function addListenTouch() {
	document.getElementById("drag").addEventListener("touchstart", touchStart, false);
	document.getElementById("drag").addEventListener("touchmove", touchMove, false);
	document.getElementById("drag").addEventListener("touchend", touchEnd, false);
	var drag = document.getElementById("drag");
	var speed = document.getElementById("speed");
}

//touchstart,touchmove,touchend事件函数
 function touchStart(e) {  
 	e.preventDefault();
 	var touch = e.touches[0];
 	startX = touch.pageX; 
 }
 function touchMove(e) { //滑动          
 	e.preventDefault();
 	var touch = e.touches[0];
 	x = touch.pageX - startX; //滑动的距离
 	//drag.style.webkitTransform = &#39;translate(&#39; + 0+ &#39;px, &#39; + y + &#39;px)&#39;;  //也可以用css3的方式     
 	drag.style.left = aboveX + x + "px"; //  
 	speed.style.left = -((window.innerWidth) - (aboveX + x)) + "px";
 }
 function touchEnd(e) { //手指离开屏幕
 	e.preventDefault();
 	aboveX = parseInt(drag.style.left);
 	var touch = e.touches[0];
 	var dragPaddingLeft = drag.style.left;
 	var change = dragPaddingLeft.replace("px", "");
 	numDragpaddingLeft = parseInt(change);
 	var currentTime = (numDragpaddingLeft / (window.innerWidth - 30)) * audio.duration;//30是拖动圆圈的长度，减掉是为了让歌曲结束的时候不会跑到window以外
 	audio.currentTime = currentTime;
 }
//3拖动的滑动条前进
function dragMove() {
	setInterval(function() {
		drag.style.left = (audio.currentTime / audio.duration) * (window.innerWidth - 30) + "px";
		speed.style.left = -((window.innerWidth) - (audio.currentTime / audio.duration) * (window.innerWidth - 30)) + "px";
	}, 500);
}
