<h2 id="概要">概要</h2>

<p>&lt;bgsound&gt;是 IE 浏览器中设置网页背景音乐的元素。</p>

<div class="note">
<p><strong>不要使用它！</strong>想要在网页中嵌入音频，应当使用{{HTMLElement("audio")}}.</p>
</div>

<h2 id="属性">属性</h2>

<dl>
 <dt>{{htmlattrdef("balance")}}</dt>
 <dd>该属性取值在-10,000 到 +10,000，它决定扬声器之间的音量如何分配。</dd>
 <dt>{{htmlattrdef("loop")}}</dt>
 <dd>该属性表明音频被播放的次数，是一个数值或者关键字 infinite。</dd>
 <dt>{{htmlattrdef("src")}}</dt>
 <dd>该属性定义了音频文件的 URL，必须是以下格式之一：.wav，.au，.mid</dd>
 <dt>{{htmlattrdef("volume")}}</dt>
 <dd>该属性值域为-10,000 到 0，它决定背景音乐的音量大小。</dd>
</dl>

<h2 id="示例">示例</h2>

<pre class="brush:html">&lt;bgsound src="sound1.mid"&gt;

&lt;bgsound src="sound2.au" loop="infinite"&gt;
</pre>

<h2 id="备注">备注</h2>

<p>类似的功能在一些版本的 Netscape 中使用&lt;embed&gt;标签来调用音频播放器。</p>

<p>你可以使用自闭合标签<code>&lt;bgsound /&gt;。然后由于它并非标准的一部分，XHTML 会认为它无效。</code></p>

<p>[1] Up to Firefox 22, even if not supporting this element, Gecko was associating it an {{domxref("HTMLSpanElement")}}. This was fixed then and now the associated element is an {{domxref("HTMLUnknownElement")}} as required by the specification.</p>
