            if(isWeiXinClient()){
                wx.ready(function() {
                     currut_audio.play();
                 });

            clearInterval(str1);
        }
    },100);
    currut_audio.addEventListener("error", function (e) {
        alert('亲，网络有延迟，请稍后重试！');

调用audio.play()不起作用，但是ios微信浏览器可以自动播放，安卓的不可以！！！
