【附图说明】
图 1是本发明实施例的微型音响的倒置示意图；
图 2是本发明实施例的盖板示意图；
图 3是本发明实施例的盖板与下壳的组合示意图。
其中： 1、 上壳； 2、 中壳； 3、 下壳； 4、 穿线孔； 5、 盖板； 51、 热熔孔； 52、 避让位。 【具体实施方式】
一种微型音响， 包括壳体和设置在所述壳体上的两个穿线孔和固定在壳体内 部防止灰尘从穿线孔进入到壳体内的盖板， 所述盖板上设置有下凹的穿线避让 位。 本发明由于在壳体上设置了用来连接挂绳的穿线孔， 通过穿线孔将挂绳与 微型音响连接在一起， 方便通过挂绳将微型音响与其他物体连接在一起； 又在 微型音响内设置防止灰尘从穿线孔进入到壳体内的盖板， 这样即使设置了穿线 孔， 灰尘也不会从穿线孔进入到壳体内。
下面结合附图和较佳的实施例对本发明作进一步说明。
如图 1至 3所示， 微型音响包括壳体、 固定在壳体内的喇叭、 电路板和为微 型音响提供电源的电池； 壳体包括上壳 1、 中壳 2与下壳 3 , 喇叭用螺丝固定在 中壳上， 中壳上设置有环所述喇叭的第一环状凸起， 上壳内壁设置有套在所述 第一环状凸起上的封闭圏， 封闭圏将喇八密封在微型音响内形成封闭的前音腔， 而下壳与中壳之间形成后音腔， 前音腔与后音腔配合， 有效的改善喇叭的重低 音的共振效果从而提高微型音响的音质。
微型音响的中间宽两端窄， 穿线孔 4两个设置在下壳 3上。 在正常使用情况 下， 下壳 3与放置部接触， 由于微型音响的中间宽两端窄， 将穿线孔 4设置在 下壳 3上， 中壳 2挡住下壳 3 , 可以防止上部的灰尘落到下壳 3上。 微型音响还 包括覆盖穿线孔 4的盖板 5 ,在盖板 5与穿线孔 4相对面上设置下凹的穿线避让 孔（图中未示出）， 盖板 5两端均设置有一个热熔孔 51 , 下壳 3设置有横跨所述 穿线孔 4两个热熔柱， 盖板 5下壳之 3的热熔固定。
