Figure imgf000003_0001
液晶显示装置以耗电低、 使用寿命长、 分辨率高等优点， 逐渐进入千家 万户， 液晶电视也逐渐成为主流电视。液晶电视的发声主要是通过内置喇叭， 液晶电视主要由面框、 液晶显示屏、 中框和后壳等组成， 液晶电视通常喇叭 是采用 "下出"或 "后出"的固定方式。 "下出"是指喇叭的振膜朝下， 声音 由显示装置的下部传出， "后出 "是指喇叭的振膜朝后， 声音由显示装置的后 部传出。 图 1和图 2为现有液晶电视后壳的结构示意图。 参见图 1和图 2， 通常液晶电视的后壳 1上设有与喇叭位置对应的出音孔 2。
传统的液晶电视的内置喇叭分为箱体喇叭和非箱体喇叭， 如图 3所示， 非箱体喇叭通常是将喇叭 10直接固定于液晶电视的中框上，非箱体喇叭的振 膜 11向前或向后运动时声波是反相的，导致声波互相抵消，存在着 "声短路" 的现象， 音质较差， 尤其是在低频部分； 如图 3和图 4 iff示， 而箱体喇叭是 通过在喇叭的外部设置箱体 20, 可以将喇叭的振膜 11 前后完全隔离开， 以 防止 "声断路"， 改善低频效应， 音质较好， 但是箱体喇叭需要单独制造喇叭 的箱体 20, 并将喇叭固定与箱体组成箱体喇叭， 再固定于液晶电视内， 其成 本较高。
本发明实施例的目的是提供一种显示装置后壳及显示装置， 该显示装置 后壳可以安装喇叭， 能够达到提升喇叭音质的同^, 降低成本的目的。
本发明所提供的技术方案如下：

进一步的， 所述箱体结构的开口处设有能够与所述开口配合， 以打开或 者封闭所述开口的封盖部件。
进一步的， 所述箱体结构有两个， 对称地分布在壳体的底部的两端。 迸一步的， 所述出音部包括所述箱体结构的开口， 且设置于所述开口处 的所述封盖部件上设有出音孔； 和 /或，
所述出音部包括设置于所述箱体结构上的出音孔。
进一步的， 所述出音部包括设置于所述箱体结构的侧壁上的出音孔。 迸一步的， 所述封盖部件包括结构与所述开口结构适配的盖板， 所述盖 板采用可拆卸的方式连接于所述开口内。
迸一步的， 所述箱体结构上设有用于固定喇叭的固定部。
进一步的， 所述封盖部件上设置有用于与所述箱体结构通过螺丝连接的 第一螺丝孔及用于与喇叭通过螺丝连接的第二螺丝孔；
所述固定部包括用于与所述第一螺丝孔配合的螺丝柱， 所述螺丝柱设置 于所述箱体结构的内部， 且位置与所述第一螺丝孔的位置相对应。
进一步的， 所述箱体结构设置于所述壳体的底部， 且所述箱体结构的开 口方向朝向 述壳体的底端。
进一步的， 所述壳体包括： 用于与显示装置的面壳相对设置的前侧面； 及， 与所述前侧面相对的后侧面； 所述箱体结构设置于所述后侧面上。

为了解决现有技术中液晶电视采用箱体喇叭成本较高， 而采用非箱体喇 叭音质较差的问题， 本发明提供了一种显示装置后壳， 其能够用来安装喇叭， 使得显示装置的喇叭音质得到提升的同时， 又不会造成成本增加。
以下结合^图对本发明的原理和特征进行描述， 所举实例只用于解释本 发明， 并非用于限定本发明的范围。
如图 6至图 8所示， 本发明所提供的显示装置后壳包括壳体 100， iff述 壳体 100上设置有 ^于容纳喇叭 300的容置腔室 200， 且所述容置腔室 200 上设有用于供喇叭 300声音传出的出音部。
采用上述方案， 显示装置的喇叭 300可以置于显示装置后壳的容置腔室 200内， 装配喇叭 300时， 使得箱体结构的出音部位于喇叭 300的振膜前方， 且使得容置腔室 200能够在各方向围设于喇叭 300的振膜的四周， 以将喇叭 300的振膜前后隔离开， 喇叭 300的振膜前方声音由出音部传出， 从而该喇 叭 300与该显示装置的容置腔室 200组成类似于箱体喇叭的结构，以防止 "声 短路"， 从而实现提升喇叭音质的目的； 并且， 该容置腔室 200是直接形成于 壳体 100上， 只需在生产壳体 100时， 对生产模具进行改进设计， 即可一体 成型得到本发明的显示装置后壳， 而无需另外单独生产和装配喇叭 300的音 箱， 由此可见， 本发明的显示装置后壳在提升喇叭 300音质的同^, 不会增 加成本； 此外， 采用本发明的显示装置后壳， 喇叭 300可以方便地装入显示 装置后壳的容置腔室 200内， 操作简便。
以下说明本发明所提供的显示装置的优选实施方式。
本实施例中， 优选的， 如图 6至图 8所示， 所述容置腔室 200是由与所 述壳体！00—体成型的箱体结构 20!构成， 所述箱体结构 201上设有开口， 该开口可以用来在安装喇叭 300时， 供喇叭 300装入箱体结构 201 内。 当然 可以理解的是， 所述容置腔室可由与所述壳体连接的箱体结构形成， 所述容 置腔室 200也可以是采用其他结构， 在此不再一一列举。
为了避免外界灰尘等由箱体结构 201 的开口迸入箱体结构 201 内破坏喇 叭 300， 本实施例中， 在箱体结构 201 的开口处设有能够与所述开口配合， 以 ίί开或者封闭所述开口的封盖部件 400。 本实施例所提供的显示装置后壳 能够在装配喇叭 300时， 利用封盖部件 400打开箱体结构 201 的开口， 将喇 叭 300从所述开口处装入箱体结构 201 内， 而在装配完成后， 利用封盖部件 400封装住箱体结构 201的开口， 以避免外界因素破坏喇叭 300。
本实施例中， 优选的， 如图 7 8所示， 该封盖部件 400包括结构与所述 开口的结构适配的盖板， 所述盖板采用可拆卸的方式连接于所述开口处。 上 述方案， 盖板与箱体结构 201 是采用可拆卸地方式进行连接的， 在装配喇叭 300时， 将盖板从箱体结构 201 的开口处拆卸下来， 将喇叭 300从所述开口 处装入箱体结构 201 内， 而在装配完成后， 将盖板安装在箱体结构 201的开 口， 以避免外界因素破坏喇叭 300。
需要说明的是， 在本实施例中封盖部件 400与箱体结构 201的开口是采 用可拆卸方式连接， 但是在实际应用中， 封盖部件 400与开口的连接方式并 不局限于此， 还可以采用其他方式进行连接， 只需保证封盖部件 400能够根 据需要打开或封闭开口即可， 比如： 封盖部件 400的一侧通过铰链与开口的 一侧边缘活动连接， 封盖部件 400类似开口一个 "门 "， 在装配喇叭 300或需 要对喇叭 300进行维修、 更换时， 封盖部件 400打开， 以打开开口即可， 而 装配完毕时， 关闭封盖部件 400， 即可关闭开口； 或者， 封盖部件 400通过 移动地连接的方式连接于开口处， 当需要密封开口时， 推动封盖部件 400移 动至开口处， 而需要打开开口时， 推动封盖部件 400移出开口即可； 在此不 再一一列举封盖部件 400与开口的连接方式。 此外， 还需说明的是， 本实施例中该封盖部件 400优选的是盖板结构， 在实际应用中， 该封盖部件 400也可以采用其他结构， 在此不再一一列举。
在本实施例中， 优选的， 该箱体结构 201上的出音部通过在开口处的封 盖部件 400的出音孔 202实现。 采用上述方案， 如图 7-8所示， 喇叭 300在 安装时， 应将喇叭 300的振膜面向封盖部件 400设置， 由此， 喇叭 300的声 音可以由封盖部件 400上的出音孔 202传出。
当然可以理解的是， 在实际应用中， 箱体结构 201上的开口处也可以不 设置封盖部件 400， 喇叭 300在安装时， 应将喇叭 300的振膜朝向开口设置， 从而整个开口作为箱体结构 20! 的出音部使用； 此外， 也可以是在该箱体结 构 201上的侧壁上设置出音孔 202作为出音部， 在此并不对出音部的具体位 置和形式进行限定。
此外， 本实施例中， 箱体结构 201上还设置有能够将喇叭 300固定在箱 体结构 201 内部的固定部。 优选的， 本实施例中， 喇叭 300通过以下方式固 定在箱体结构 201的内部：
如图 6至图 8所示， 所述封盖部件 400上设置有用于与所述箱体结构通 过螺丝连接的第一螺丝孔 401及用于与喇叭 300遥过螺丝连接的第二螺丝孔 (图中未标出 所述固定部包括用于与所述第一螺丝孔 401 配合的螺丝柱 205 , 所述螺丝柱 205设置于所述箱体结构 201的内部， 且位置与所述第一螺 丝孔 401的位置相对应。
采用上述方案， 喇叭 300上设置有安装孔， 在第二螺丝孔和喇叭 300的 安装孔内穿装螺丝， 可以将喇叭 300固定在封盖部件 400上， 再在第一螺丝 孔 401和螺丝柱内穿装螺丝， 可以将封盖部件 400固定在箱体结构 201的开 口处， 从而将喇叭 300固定在箱体结构 201内。
当然可以理解的是， 在实际应用中， 喇叭 300还可以采 ^其他方式固定 在箱体结构 201内， 比如喇叭 300直接与箱体结构 201内的螺丝柱通过螺丝 连接等， 在此不再一一列举； 此外， 封盖部件 400也可以采 ^其他可拆卸方 式安装于箱体结构 201的开口处， 比如， 封盖部件 400采用卡合的方式可拆 卸地安装于箱体结构 201的开口处。
此外， 显示装置， 尤其是液晶电视通常喇叭 300是采用 "下出"或 "后 出"的固定方式。 "下出"是指喇叭 300的振膜朝下， 声音由显示装置的下部 传出， "后出"是指喇叭 300的振膜朝后， 声音由显示装置的后部传出。 需要 说明的是， 本说明书中所指的 "下"、 "后"、 "底部"和 "后部"等方位均与 显示装置在正常显示工作状态下人的视角所观察到的各方位一致。
本实施例所提供的显示装置中， 优选的， 如图 6所示， 显示装置后壳的 壳体 100结构设置于所述壳体 100的底部， 且所述箱体结构 201的开口方向 朝向所述壳体 100的底端。 采用上述方案， 该显示装置后壳组装成的显示装 置其喇叭 300可以采用 "下出" 的固定方式， 如图 7所示， 采用上述方案， 箱体结构 201设置于壳体 100的底端， 且箱体结构 201的开口朝下， 而喇叭 300的振膜朝下固定于箱体结构 201 内， 即可将喇叭 300采用 "下出" 的固 定方式固定于显示装置后壳上。
当然可以理解的是， 在实际应用中， 还可以是箱体结构 201 的开口方向 朝向壳体 100的后方， 开口处的封盖部件 400上不设置出音孔 202, 而是在 箱体结构 20! 的底部侧壁上开设出音孔 202， 并将喇叭 300的振膜朝下固定 于箱体结构 201 内， 也可以实现将喇叭 300采用 "下出" 的固定方式固定于 显不装置 壳上。
此外， 在实际应 ^中， 箱体结构 201 的开口也可以朝向该显示装置后壳 的后方， 相应地， 将喇叭 300的振膜朝后固定于箱体结构 201 内， 即可将喇 叭 300采用 "后出" 的固定方式固定于显示装置后壳上。 或者， 也可以是箱 体结构 201的开口朝向壳体 100的底端，而封盖部件 400上不设置出音孔 202， 仅在箱体结构 201 的后侧壁上开设出音孔 202， 并将喇叭 300的振膜朝后固 定于箱体结构 201 内， 也可以实现将喇叭 300采用 "后出" 的固定方式固定 于显示装置后壳上。
此外， 本实施例中优选的， 箱体结构 201 有两个， 分别分布在壳体 100 的底部的两端， 优选为对称地分布在壳体 100的底部的两端。 当然在实际应 ^中， 箱体结构 201的数量可以进行调整。
通常， 显示装置后壳的壳体 100包括： 与显示装置的面壳相对设置的， 位于靠近显示装置的显示屏一侧的前侧面； 以及， 与所述前侧面相对的， 位 于远离显示装置的显示屏一侧的后侧面。 由于显示装置后壳的前侧面与显示 装置的面壳扣合， 显示屏等设置于后壳与面壳之间， 为了避免显示装置后壳 上的箱体结构 201与显示屏千涉， 如图 6至图 8所示， 本实施例中， 优选的， 该箱体结构 201设置于所述壳体 100的后侧面上。
此外， 如图 6至图 8所示， 该箱体结构 20!的侧壁上还可以设置散热孔 203，并且在箱体结构 201的侧壁上还可以设置用于供用于喇叭与显示装置内 的部件进行电连接的过孔 204。
此外， 需要说明的是， 本发明所提供的显示装置后壳优选的可以为液晶 电视后壳， 当然也可以为液晶显示器后壳或其他液晶显示装置的后壳。
此外， 本发明还提供了一种显示装置， 其包括显示屏、 喇叭 300和后壳， 所述后壳采用如上所述的显示装置后壳； 所述喇叭 300置于所述显示装置后 壳的箱体结构 201内， 且所述喇叭 300的振膜面向所述箱体结构 20! 的出音 部设置。 所述显示装置可以是液晶电视、 液晶显示器等。
以上所述仅是本发明的优选实施方式， 应当指出， 对于本技术领域的普 通技术人员来说， 在不脱离本发明原理的前提下， 还可以做出若千改进和润 饰， 这些改进和润饰也应视本发明的保护范围。
