Description

一种迷你音响
【技术领域】
本发明涉及音响领域， 更具体的说， 涉及一种迷你音响。 【背景技术】
迷你音响（mini-speaker ) 是一种微型音响， 4艮多人也称其为 "USB音响"， 以 USB接口连接电脑或 USB插孔， 小巧， 方便携带， 款式新颖。 迷你音箱只需 与笔记本电脑、 手机等设备连接， 无需电源供给， 就能播放音乐。
本人已设计一种迷你音响， 包括壳体， 设置在壳体内部的喇叭、 振动膜和 电路板； 所述的振动膜用振动膜固定框固定在喇八和电路板之间， 喇八和电路 板之间用导线连通， 振动膜固定框上设置有导线避让孔， 且导线避让孔的孔径 正好可以通过导线； 振动膜固定框包括外框和设置在外框内的振动膜避让孔， 振动膜用胶水固定在振动膜避让孔的侧壁上， 振动膜固定框与壳体之间过盈配 合， 振动膜固定框用胶水固定在壳体内部； 电路板的形状与所述壳体的形状相 适应， 电路板直接固定在壳体内部的振动膜固定框的一侧； 所述的喇八的形状 与所述电路板的形状相适应， 所述的喇叭直接放置在壳体内部的振动膜固定框 的另一侧。 此方案未公开。 但是喇叭直接放置在壳体的内部， 这样喇叭固定不 牢靠， 在携带时会来回晃动； 且喇叭位于振动膜的一侧， 这样喇叭晃动可能会 砸在振动膜上造成振动膜的损坏， 从而影响振动膜的使用效果。
【发明内容】
本发明所要解决的技术问题是提供一种将喇八有效固定的迷你音响。
本发明的目的是通过以下技术方案来实现的： 一种迷你音响， 喇叭、 一端 设置有第一开口的主体和封闭所述第一开口的盖板； 所述盖板包括一中间设置 有出音孔的面板和设置在所述面板一面且环所述面板的凸出的第一插入部， 所 述第一插入部与所述主体紧密配合， 所述出音孔的孔径小于所述喇叭的直径； 所述喇八用胶水固定在所述盖板的出音孔的边缘。
优选的， 所述盖板还包括设置在所述面板上与所述出音孔中心相同的且内 径等于所述喇叭直径的凸出的环状的第一限位凸起， 所述第一限位凸起与所述 第一插入部位于所述面板的同一面。 这样第一限位凸起与出音孔之间就形成了 一个外径等于喇叭的直径且内径小于喇叭直径的喇八放置平台， 这样用胶水将 喇叭固定在喇八放置平台上就可以将喇叭固定在盖板上了。
优选的， 所述壳体整体呈方块状， 所述主体的长度和宽度相同， 所述面板 的长度与宽度也相同且等于所述主体的长度， 所述第一插入部之间的外距等于 所述主体的内径。 这是迷你音响的外形， 将迷你音响的长度和宽度设置相同， 既能够充分的利用壳体的体积， 又能够有效的固定设置在壳体内部的部件。
优选的， 所述第一插入部中间位置处设置有长条状开口。 只要在盖板的每 个拐角处设置第一插入部就可以将盖板固定在主体的第一开口处， 且设置长条 状的开口， 可以减轻迷你音响的整体重量。
优选的， 所述第一插入部的根部的内侧设置有凸出的条状加强筋， 所述第 一限位凸起的高度与所述第一插入部之间的高度相同。 设置条状加强筋， 可以 增强第一插入部的强度， 防止在固定盖板时， 第一插入部受力过大， 发生损坏。
优选的， 所述面板的边缘设置有大于 90度小于 180度的倒角。 在面板的边 缘设置倒角可以防止在使用时， 面板刮伤使用者的手。
优选的， 所述的迷你音响还包括一覆盖所述出音孔的喇八网， 所述的喇八 网固定在所述盖板上。 设置喇叭网可以防止出音孔进入灰尘。
优选的， 所述喇叭网上设置有至少两个向外凸出的插骨， 所述盖板上设置 有与所述插骨插接的插孔。 采用插接的方式将喇叭网固定在盖板山。 优选的， 所述盖板上设置有下凹的用于放置所述喇八网的放置平台， 所述喇八网放置台 下凹的高度等于所述喇叭网的厚度。 设置喇叭网放置平台可以保证喇叭网固定 后面板的平整度。
优选的， 所述喇叭网采用铁质材质。 铁的硬度较大， 不易损坏； 而且价格 便宜， 易获得。
本发明由于喇叭用胶水固定在盖板上， 使得喇叭不会从盖板上掉落， 而且 盖板又采用插入固定的形式固定在迷你音响的主体上， 插入固定的固定效果较 好使得盖板不会滑落在主体内部， 从而使得喇叭在迷你音响内牢固固定， 在移 动或者使用时喇叭不会晃动也不会脱落。

【具体实施方式】
一种迷你音响， 喇叭、 一端设置有第一开口的主体和封闭所述第一开口的盖 板； 所述盖板包括一中间设置有出音孔的面板和设置在所述面板一面且环所述 面板的凸出的第一插入部， 所述第一插入部与所述主体紧密配合， 所述出音孔 的孔径小于所述喇八的直径； 所述喇八用胶水固定在所述盖板的出音孔的边缘。 本发明由于喇叭用胶水固定在盖板上， 使得喇叭不会从盖板上掉落， 而且盖板 又采用插入固定的形式固定在迷你音响的主体上， 插入固定的固定效果较好使 得盖板不会滑落在主体内部， 从而使得喇叭在迷你音响内牢固固定， 在移动或 者使用时喇叭不会晃动也不会脱落。
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 1-8所示， 迷你音响 1 包括喇叭 7和一端设置有第一开口 21的主体 2 和盖板 3。 盖板 3包括中间设置有出音孔 32的面板和设置在面板的边缘且环面 板的凸出的且与与面板相互垂直第一插入部 31 ,第一插入部 31与主体 2之间紧 密配合， 盖板 3插入固定在主体 2的第一开口 21处。 喇叭 7用胶水固定在第一 插入部 31内的盖板 3上， 在盖板 3上设置有孔径小于喇叭 7直径的出音孔 32, 这样喇叭 7就牢固的固定在盖板 3上， 不会出现喇叭 7在迷你音响 1 内晃动的 情况了。 喇叭 7与盖板 3的固定示意图参见图 7。
盖板 3上还设置有一与出音孔 32中心相同且内径等于喇叭 7直径的环状的 第一限位凸起 33 , 那么第一限位凸起 33与出音孔 32之间就形成了一个外径等 于喇八 7的直径且内径小于喇八 7直径的喇八放置平台 34, 这样用胶水将喇八 7固定在喇八放置平台 34上就可以将喇叭固定在盖板 3上了。 盖板 3的面板的 边缘设置有大于 90度小于 180度的倒角， 可以防止在使用时， 面板刮伤使用者 的手。
如图 5所示， 第一插入部 31中间位置处设置有长条状开口， 第一插入部 31 的根部的内侧设置有凸出的条状加强筋 35 ,且第一限位凸起 33的高度与第一插 入部 31之间的高度相同。 盖板 3采用塑胶注塑一体成型， 在盖板 3的面板的边 缘设置大于 90度小于 180度的倒角， 可以防止在使用时， 盖板 3刮伤使用者的 手。
为了方便描述， 在这里规定： 盖板 3设置有第一插入部 31的面为盖板的背 面， 与背面相对的面为正面。 迷你音响还包括一喇叭网 8。 喇叭网 8固定在盖板 3的正面， 喇叭网 8覆盖出音孔 32, 且喇叭网 8的形状与盖板 3的形状相适应。 主体 3呈方块状， 那么盖板 3与喇叭网 8均呈方块状， 在喇叭网 8的四个拐角 均设置有向外凸出的且与喇叭网 8相互垂直的插骨 81 , 盖板 3的面板上设置有 与插骨 81相对应的插孔。 为了保证喇叭网 8固定后面板的平整度， 在盖板 3的 正面设置有与喇叭网 8厚度相同的下凹的喇叭网放置台 36。 喇叭网 8与盖板 3 的组合示意图， 参见图 8。 铁的硬度较好且易获得， 在这里喇叭网 8采用铁质材 料注塑而成。
迷你音响 1还包括固定在主体 2内部的振动膜、 振动膜固定框和电路板。 振 动膜用胶水固定在振动膜固定框上， 振动膜固定框与主体 2之间紧密配合用胶 水固定在主体内部。 电路板上设置有连接外接 usb数据线的 usb接口， 对应的在 主体上设置有与 usb接口相对应的 usb插口。
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。
