【发明内容】
本发明所要解决的技术问题是提供一种可方便拆卸、 音质较好的微型音箱。 本发明的目的是通过以下技术方案来实现的：
一种微型音箱， 包括音频线、 音频插头、 音箱壳体、 喇叭、 电路板、 共鸣 腔， 共鸣腔是中空的， 所述共鸣腔是伸缩共鸣腔， 所述音箱壳体包括音箱上壳 和音箱下壳， 所述伸缩共鸣腔的一端与音箱上壳连接， 另一端与音箱下壳连接。
优选的， 所述伸缩共鸣腔的一端设有开口。 由于要通音， 伸缩共鸣腔要留 开口与音源连接。
优选的， 所述音箱上壳的一个面设有孔， 所述喇叭位于伸缩共鸣腔内。 喇 八位于伸缩共鸣腔内， 节省空间。
优选的， 所述伸缩共鸣腔的另一端也设有开口。 当共鸣腔压缩时， 另一端 也设有开口可以将喇叭的一个面穿过该开口， 使得共鸣腔压缩量大， 有利于音 箱的微型化。
优选的， 所述伸缩共鸣腔的呈圓柱体。 此为伸缩共鸣腔的一种形状。
优选的， 所述伸缩共鸣腔由多层先凸出后凹陷的软质弹性材料组成， 每层 材料的 EJ陷部分连接在一起， 当伸缩共鸣腔呈伸展状态时， 各层的 陷部分展 开， 当所述伸缩共鸣腔呈压缩状态时， 各层的凹陷部分也相应的压缩在一起。 此为伸缩共鸣腔处于两种状态的方式。
优选的， 当伸缩共鸣腔处于压缩状态时， 音箱上壳和音箱下壳可通过卡位 结构连接在一起。 伸缩共鸣腔处于压缩状态时， 音箱上壳和音箱下壳卡接在一 起能减少微型音箱占用的空间， 达到便携的目的。
优选的， 所述伸缩共鸣腔的切面是圓形。 此为伸缩共鸣腔的一种形状。 优选的， 所述伸缩共鸣腔的切面是正方形。 此为伸缩共鸣腔的另一种形状。 优选的， 所述伸缩共鸣腔的切面是长方形。 此为伸缩共鸣腔的另一种形状。 本发明由于音箱壳体包括音箱上壳和音箱下壳， 所以使得音箱更容易拆卸， 同时音箱的共鸣腔是可伸缩的， 在占用同样的空间下， 提升了微型音箱的音质。
【附图说明】
图 1是本发明微型音箱的示意图；
图 2是本发明伸缩共鸣腔的示意图。
其中： 1、 音箱上壳； 2、 音箱下壳； 3、 伸缩共鸣腔； 4、 陷部分； 5、 卡 位结构。
【具体实施方式】
下面结合附图和较佳的实施例对本发明作进一步说明。
本发明的一种微型音箱， 包括音频线、 音频插头、 音箱壳体、 喇叭， 电路 板、 共鸣腔， 共鸣腔是中空的， 所述共鸣腔是伸缩共鸣腔， 所述音箱壳体包括 音箱上壳和音箱下壳， 所述伸缩共鸣腔的一端与音箱上壳连接， 另一端与音箱 下壳连接。
如图 1及图 2所示， 所述伸缩共鸣腔 3的一端设有开口。 所述喇八位于伸 缩共鸣腔 3内。 喇八位于伸缩共鸣腔 3内， 节省空间 （喇八图中未示出）。 由于 要通音， 伸缩共鸣腔要留开口与音源连接。 所述伸缩共鸣腔呈圓柱体。 此为伸 缩共鸣腔的一种形状。
如图 2所示， 所述伸缩共鸣腔 3由多层先凸出后凹陷的软质弹性材料组成， 每层材料的凹陷部分 4连接在一起。
当伸缩共鸣腔呈伸展状态时， 各层的凹陷部分 4展开， 当所述伸缩共鸣腔 呈压缩状态时， 各层的凹陷部分 4也相应的压缩在一起。 此为伸缩共鸣腔处于 两种状态的方式。
所述伸缩共鸣腔的另一端也设有开口。 当共鸣腔压缩时， 另一端也设有开 口可以将喇叭的一个面穿过该开口， 使得共鸣腔压缩量大， 有利于音箱的微型 化。
当伸缩共鸣腔处于压缩状态时， 如图 1所示， 音箱上壳 1和音箱下壳 2可 通过卡位结构 5 连接在一起。 伸缩共鸣腔处于压缩状态时， 音箱上壳和音箱下 壳卡接在一起能减少微型音箱占用的空间， 达到便携的目的。
