Description

电脑
技术领域
本发明是涉及一种电脑。
背景技术
随着电子产业的快速发展，电脑也越来越普及化。目前，电脑主要包括一主机以及显示器，然而，上述电脑中的显示器需要占据较大的空间，不利于电脑向短、小、轻、薄的方向发展，因此，需加以改进。
发明内容
有鉴于此，有必要提供一种结构简单的电脑。
一种电脑，包括一主机，该主机包括一外壳以及设于该外壳内的一电路板，该主机还包括设于其外壳内的一投影***，该投影***与该电路板电性连接，该外壳上设有一投影孔，该投影***与该投影孔对准，该投影***用来将电路板传来的信号由投影孔投射出去。该主机还包括设于其外壳内的一虚拟键盘***，该虚拟键盘***与该电路板电性连接，该外壳上设有一投射孔，该虚拟键盘***与该投射孔对准，并通过该投射孔在该主机外形成一虚拟键盘。该虚拟键盘***包括两个激光二极管，其中一个激光二极管发出激光并通过投射孔在主机外形成一虚拟键盘，另一个激光二极管发出激光并在投影的虚拟键盘下方投影出一个隐形的感应平面，用于感测使用者触碰键盘的手指的位置。
上述电脑中，其主机内设有与电路板电性连接的投影***，并于该主机的外壳上设置与该投影***对准的投影孔，从而使该电脑不需要额外的显示器即可实现显示信号的目的，结构简单，并可减小该电脑所占据的空间，便于携带与操作。
下面参照附图，结合具体实施例对本发明作进一步的描述。
附图说明
图1为本发明一较佳实施例中电脑的立体图。
图2为图1所示电脑另一视角的立体图。
图3为图1所示电脑拿开盖体后的立体示意图。
图4为图1所示电脑的工作示意图。
具体实施方式
图1及图2所示为本发明一较佳实施例中电脑的立体图，在本实施例中，该电脑为一桌上型电脑，其包括一主机10。
请同时参照图3，该主机10包括一外壳11、一电路板12、一投影***13、一摄像***14以及一虚拟键盘***15。该电路板12、投影***13、摄像***14以及虚拟键盘***15设于该外壳11内，该投影***13、摄像***14以及虚拟键盘***15分别与该电路板12电性连接。
请再参照图1，该外壳11包括一壳体111以及与该壳体111结合的一盖体112，该壳体111的一侧上设有一摄像孔113、若干USB接口116、一投射孔115、一电源开关117以及一电源线插孔118。请再参照图1，该壳体111的另一侧上设有一投影孔114，该投影孔114与该投射孔115分别位于该壳体111相对的两侧面上。
请继续参照图3，该摄像***14与该壳体111上的摄像孔113对准，从而使该摄像***14可通过摄像孔113摄取外界的视频信号，该摄像***14的结构以及工作原理与现有摄像***的结构以及工作原理相同，并可充当普通摄像头使用，用于抓取人物头像。
该虚拟键盘***15与该壳体111上的投射孔115对准，该虚拟键盘***15内设有两个激光二极管(图未示)以及一影像感测器(图未示)，在本实施例中，该影像感测器采用Omnivision公司具有公用中分辨率格式(CommonIntermediate Format，CIF)解析度的CMOS影像感测器。
该投影***13集成于该壳体111内，并与该壳体111上的投影孔114对准，该投影***13用以将电路板12传来的信号由投影孔114投射出去，该投影***13的结构以及工作原理与现有投影仪的结构以及工作原理相同。
请同时参照图4，当该电脑工作时，该虚拟键盘***15内的一个激光二极管发出激光并通过投射孔115，根据绕射光或全像光学原理进行投影，以在主机10外形成一虚拟键盘16(如图4所示)，从而为使用者提供一个与普通键盘一样的操作环境；另一个激光二极管发出激光并在投影的虚拟键盘16下方投影出一个隐形的感应平面(图未示)，当使用者操作该虚拟键盘16，并且其手指经过较低的隐形的感应平面时，激光就会被反射回该虚拟键盘***15，并被该虚拟键盘***15内的影像感测器感测，并将感测到的信号传送至电路板12，该感测到的信号经过电路板12处理分析，从而确定虚拟键盘上的哪些键被占据，哪些键仍然可见，由此推断出使用者的手指的具***置，以确定实际的输入动作，再转换成输入信号传送至投影***13，该投影***13最后将该电路板12处理后的输入信号转换成图像信号并由投影孔114投射出去，该投射出来的图像信号投射到一墙壁(图未示)或其他投射屏幕上，从而可形成一显示屏17，达到显示信号的目的。
上述电脑中，其主机10内设有与电路板12电性连接的投影***13以及虚拟键盘***15，并于该主机10的外壳11上设置与该投影***13以及虚拟键盘***15分别对准的投影孔114以及投射孔115，从而使该电脑不需要额外的键盘以及显示器即可实现输入信号以及显示信号的目的，结构简单，并可减小该电脑所占据的空间，有利于电脑向短、小、轻、薄的方向发展，便于携带与操作。
在实际应用中，也可用现有的普通键盘取代上述虚拟键盘***15来实现输入，此时由于电脑的主机10内集成了投影***13，因此仍可省去现有电脑中使用的显示器，从而达到减小电脑所占据的空间的功效。
