本文实例为大家分享了微信小程序实现播放音频的具体代码，供大家参考，具体内容如下
wxml：
<!-- 语音 -->
<view wx:if="{{content.mp3.length > 0 }}">
<view class='audio' bindtap='musicStart'>
<view class='audio_btn'>
<image src='/img/btn_play3.webp' class='image-full' wx:if="{{playStatus}}"></image>
<!-- 未播放-->
<image src='/img/btn_stop@2x.webp' class='image-full' wx:else catchtap='canel_handover'></image>
<!-- 播放中-->
</view>
<view class='audio_pro'>
<slider class="drag" step="10" value="{{curTimeVal}}" max="{{duration}}" backgroundColor="#efefef" activeColor="#90BED5" />
</view>
<text class='audio_text'>{{formatedPlayTime}}</text>
</view>
</view>
