下面结合附图和较佳的实施例对本发明作进一步说明。
本发明公开一种便携式微型音箱，作为本发明实施例一，如图 1至图 3所示， 包括一端设有用于悬挂的挂孔的壳体和固定在所述壳体内的喇叭 4及电路板 3 , 所述壳体内设有用于限位所述电路板 3 的限位件。 本发明由于壳体内表面上设 有用于限位电路板 3的限位件， 通过限位件可以把电路板 3限位固定在壳体内， 防止电路板 3晃动， 从而使电路板 3牢固的固定在壳体内。
本实施例中， 所述限位件为设置在所述壳体内表面上的凸块 12, 所述凸块 12两个一组， 一组中的两个凸块 12相邻设置形成一开口 11 , 所述电路板 3放 置在所述开口 11处， 电路板 3放置在一组凸块 12之间的开口 11内， 从而两个 凸块 12对电路板 3进行限位固定，这样电路板 3就被牢固的限位固定在凸块 12 之间。
如图 2和图 3所示， 所述壳体包括前壳 1和后壳 2, 所述凸块 12为四组， 所 述前壳 1设置对称的两组， 所述后壳 2设置对称的两组与所述前壳 1上的两组 对应； 这是设置凸块的一种具体方式， 这样设置凸块 12, 对电路板四处固定， 这样设置使电路板固更加牢固。
本实施例中， 所述开口 11的宽度等于所述电路板 3边沿放置在所述开口 11 处的厚度， 开口 11的宽度等于电路板 3边沿厚度， 从而电路板 3放置在开口 11 处时需要用力插入才能放置到开口 11处， 当电路板 3放置在开口 11处时， 开 口 11两侧的凸块 12对电路板 3都有作用力， 从而使电路板 3固定更加牢固。
本实施例中， 所述凸块 12的大小从其顶部向下逐渐增大， 这样设置凸块 12 方便电路板 3插入到开口 11处。 所述凸块 12上设有加强筋， 加强筋位于凸块 外表面上且与壳体一体设置， 设置加强筋增加凸块 12的强度。
如图 1所示， 所述电路板 3上设有用于指示便携式微型音箱工作状态的指示 灯 31 , 前壳上设有用于避让指示灯 31的避让孔； 设置指示灯 31便于观看便携 式微型音箱的工作状态， 从而方便使用。 电路板 3通过导线连接一用于控制便 携式微型音箱的控制开关 5 , 通过开关 5方便控制便携式微型音箱， 进而方便使 用。
本实施例中， 所述便携式微型音箱还包括一可充电电池， 便携式微型音箱内 置电池， 可随时随地使用； 电池电量用完可进行充电， 不必经常更换电池； 从 而方便使用。
作为本发明实施例二， 与实施例一的区别在于， 所述限位件为 L型结构， 所 述壳体包括前壳和后壳， 所述前壳和后壳分别设有两个限位件， 这是限位件的 又一结构， 这样设置限位件同样能够把电路板牢固的限位固定在壳体内。
作为本发明实施例三， 与实施例的区别在于， 所述限位件中部设有一用于放 置所述电路板的开槽， 所述壳体包括前壳和后壳， 所述前壳和后壳分别设有两 个限位件， 这是限位件又一结构， 这样设置限位件同样能够把电路板牢固的限 位固定在壳体内。
当然， 电路板 3也可以通过其它结构限位、 固定在壳体内。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明， 不能 认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通技 术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干筒单推演或替换， 都应当视为属于本发明的保护范围。
