本发明的较佳实施方式
下面结合附图对本发明实施例作详细说明。 需要说明的是， 在不冲突的 情况下 , 本申请中的实施例及实施例中的特征可以相互任意组合。
本发明的实施例通过在投影装置中设置投影单元， 将手机等终端设备播 放时的屏幕内容进行投影放大， 方便多人同时观看终端设备播放的内容； 同 时， 考虑镜头焦距， 以及方便不同终端设备播放的问题， 将固定终端设备的 固位装置设置为位置可移动， 大小可调节的装置； 考虑终端设备电量有限， 增加线槽连接电源线对终端设备进行供电。
上述终端设备可以为手机， 平板电脑， MP4播放器等屏幕能够自发光的 设备； 本发明实施例中以终端设备为手机作为说明， 但是， 本发明内容并不 限于手机， 同样适用于其他的终端设备， 其他终端播放器使用本申请的投影 装置进行投影播放， 应当同样视为本申请的保护范围。
请参考图 1和图 2, 其中， 图 1为本发明一实施例中提供的投影装置立 体结构的示意图； 图 2为本发明一实施例中提供的投影装置俯视结构的示意 图。
本发明实施例提供的投影装置包括可闭合的壳体， 在所述壳体内部形成 腔室， 在所述壳体的端部设置有投影单元 2, 所述投影单元 2连接所述壳体 内部形成的腔室和所述壳体外表面； 在所述壳体内部形成的腔室内设置有固 位装置 3 ; 所述的壳体为不透光材料形成封闭腔室， 例如塑料、 木板、 纸板 等， 其中固位装置 3设置成固定终端设备， 投影单元 2设置成将上述终端设 备屏幕显示的内容进行投影放大， 供多人同时观看； 其中， 在播放时， 投影 单元 2正对着上述终端设备的屏幕。 手机屏幕显示的内容， 经过投影单元的 放大， 能够将手机播放内容实时投影放大， 不同的人通过观看投影即可分享 小屏幕手机播放的内容。 当然， 所述壳体上并非都要设定固位装置 3 , 只要 能够将手机屏幕正对所述的投影单元 2, 不设置所述的固位装置， 直接将手 机放在壳体形成的腔室中也是可以的。
所述投影单元 2包括一凸透镜， 利用凸透镜光学原理为基础， 将手机屏 幕置于凸透镜的 1倍焦距到 2倍焦距之间的位置， 通过手机屏幕自身发光的 亮度， 将屏幕内容通过凸透镜放大形成放大的实像， 达到投影手机播放内容 的目的。
为了使手机屏幕播放的内容能够清楚投影出来， 手机屏幕与投影单元 2 之间的距离有必要根据实际情况进行调整， 在本实施例中， 可以设置所述固 位装置 3为可移动的固位装置， 在播放过程中， 如果投影模糊， 可以将上述 固位装置的位置在靠近所述投影单元 2或者远离所述投影单元 2的方向上进 行调整， 以保证固定在所述固位装置 3上的手机屏幕与所述投影单元之间的 距离能够满足所述镜头的聚焦需求。 所述固位装置 3还可以设置为大小可调 的固位装置； 这样， 在使用不同尺寸大小的手机进行投影播放时， 根据不同 手机的屏幕尺寸大小， 能够调整所述固位装置 3的大小， 以确保不同的手机， 不同的屏幕尺寸同样可以正对着所述投影单元 2。 本发明提供的投影装置的壳体可以包括上盖体 11以及下盖体 12; 其中， 上盖体和下盖体均由不透光的材料构成， 可以是塑料、 木板、 纸板或者其他 不透光材料； 所述下盖体 12设置成承载投影器件， 所述上盖体 11 , 与所述 下盖体活动连接， 其设置成在投影播放时遮挡外部光线， 提高投影的清晰度。 上下盖体可以开合， 其连接方式可以为合页式连接， 也可以为导轨式滑动连 接， 以及可以上盖体与下盖体完全分离。
在所述壳体上还可以设置有线槽 4, 其中， 所述线槽 4可以供电源线、 耳机线或者其他的线缆通过； 方便与腔室内的手机连接， 现有的手机的电池 容量极其有限， 在使用手机进行播放时， 尤其进行视频播放时， 一般难以满 足长时间播放的需求， 因此， 有必要在使用手机进行播放时连接电源线， 使 用外部电源进行供电， 从而可以长时间的播放； 另外， 可以通过所述线槽 4 中的耳机线连接扬声器， 方便将播放的声音外接扬声器等操作。
另外， 也可以在所述壳体内部形成的腔室内设置扬声器 6; 所述扬声器 6 连接手机并将手机的声音信号通过扬声器进行播放； 虽然， 大多数手机自带 扬声器， 可以满足基本播放需求， 但是， 如果播放环境比较嘈杂， 或者观看 者距离手机比较远， 则难以听清楚手机播放的声音； 而且， 有些手机上的扬 声器声音比较小甚至部分手机没有扬声器输出， 这样， 手机声音小或者没有 设置扬声器的手机在进行投影播放时， 观看者无法听清楚声音； 在壳体内部 形成的腔室内设置扬声器 6来接收手机信号， 对外输出声音， 更能够满足各 种手机的播放。 还可以在壳体上设置调节扬声器音量大小的开关控制器 7 , 可以才艮据实际需求改变声音输出音量的大小。
可以在所述壳体上设置通孔 5 , 所述通孔 5在进行投影播放时， 能够方 便手机声音及时向外传播， 不会出现声波叠加造成传出的声音无法听清楚； 另外的， 设置所述通孔 5也方便手机在播放过程产生的热量通过所述通孔 5 向外散发。
请参考图 3 , 图 3为本发明一实施例中提供的投影装置播放方法的流程 图； 包括以下步骤：
S301 : 将终端设备固定于壳体内部形成的腔室内的固位装置上， 使终端 设备的屏幕正对投影单元； 其中， 所述终端设备可以为手机、 平板、 MP5播 放器或者其它终端设备播放器。
S303 : 调整终端设备的屏幕亮度， 打开要播放的内容； 其中， 屏幕的亮 度的调整为能够看清楚屏幕内容的前提下的最亮值为好； 如果手机屏幕亮度 太低， 通过投影单元投影播放后， 容易由于亮度不够而无法看清楚播放内容， 如果屏幕的亮度太亮， 则可能导致播放内容被背光覆盖， 无法区分播放的内 容。
S305: 进行投影播放。
在将终端设备固定于壳体内部形成的腔室内的固位装置的步骤之前， 所 述方法可以包括： 开启投影装置的上盖体； 在打开要播放的内容的步骤之后， 所述方法还可以包括： 关闭投影装置的上盖体。
将终端设备固定于壳体内部形成的腔室内的固位装置上， 使终端设备的 屏幕正对投影单元的步骤包括： 通过调整固位装置的大小和 /或位置， 使所述 终端设备的屏幕正对所述投影单元。 根据光学成像的原理， 调整屏幕相对于 镜头的位置， 使屏幕位于所述投影单元的最佳聚焦位置， 通过屏幕自身发光， 将屏幕内容通过投影单元形成放大的实像， 从而达到投影放大的目的。 打开需要播放的内容的步骤之后， 所述方法还可以包括： 终端设备的电 源线可以通过线槽连接终端设备对上述终端设备进行供电， 以及终端设备的 耳机线通过线槽外接外部的扬声器， 将声音信号输出。
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， 还可以做出若干简单推演或 替换， 都应当视为属于本发明的保护范围。
工业实用性 本发明实施例可以方便多人分享共同观看， 并可以方便播放的终端设备 连接电源线或者耳机线的需求， 保证了终端设备不会因为电池容量有限而无 法长时间播放， 同时可以有效扩大播放的音量， 解决部分终端播放器音量小 而听不清楚的问题。
