</audio>

<audio id="myAudio" src="audio.mp3" type="audio/mpeg"></audio>
<button onclick="playAudio()">播放</button>
<button onclick="pauseAudio()">暂停</button>
<button onclick="setVolume(0.5)">调整音量</button>

<script>

  function playAudio() {
    audio.play();
  }

  function pauseAudio() {
    audio.pause();
  }

  function setVolume(volume) {
