加入一下代码即可：

function audioAutoPlay(id) {
                var audio = document.getElementById(id);
                audio.play();
                document.addEventListener("WeixinJSBridgeReady", function () {
                    audio.play();
                }, false);
                document.addEventListener('YixinJSBridgeReady', function () {
                    audio.play();
                }, false);
            }
            audioAutoPlay('Jaudio');
            if (/i(Phone|P(o|a)d)/.test(navigator.userAgent)) {
                $(document).one('touchstart',
                    function (e) {
                        $('#Jaudio').get(0).touchstart = true;
                        $('#Jaudio').get(0).play();
                        return false;
                    });
            }
