小程序需要添加音效和背景音乐，网络加载会有一定延迟，音效文件也不大，直接打包进小程序
修改config/index.jx
{
...
copy: {
patterns: [
{ from: 'src/audio/', to: 'dist/audios/', ignore: ['*.js'] }, //把src下audio目录复制到编译后的dist/audios目录
],
options: {
}
}
点击按钮时播放音效
const click = () => {
const innerAudioContext = Taro.createInnerAudioContext()
innerAudioContext.autoplay = false
innerAudioContext.loop = false
innerAudioContext.src = `audios/test.mp3`
innerAudioContext.play()
}
