//远程地址：

this.voice_back = wx.createInnerAudioContext();

var back_url = "http://ossall.5iape.com/upload/allmusic/beijing/yxjjs.mp3";

 this.voice_back.src = back_url; // src 可以设置 http(s) 的路径，本地文件路径或者代码包文件路径

this.voice_back.loop = true;//循环播放，详细查看微信的API

this.voice_back.play();

//本地地址：

this.voice_fail.src = cc.url.raw('resources/sounds/fail.mp3',);

this.dq_view_js.voice_back.pause();

this.voice_ok.play();               

this.voice_ok.onEnded(()=>{

    this.dq_view_js.voice_back.play();
