Embodiment Construction
[0016] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0017] The present invention comprises: a convex lens 1, a plane mirror 2, a place for placing a mobile phone 3, and a pulling focus 4. Through a mobile phone projector based on the principle of pinhole imaging, this method improves the convenience of viewing movies and enhances the special experience. Put the mobile phone in the inner box, adjust the position of the inner box, and pull up the bracket to adjust the angle, so that the image reflected by the plane mirror will form a positive enlarged reality after passing through the convex lens, so as to achieve the effect of a projector.
[0018] The unexplained parts involved in the present invention are the same as the prior art or implemented by adopting the prior art.

The invention is applicable to a DIY simple mobile phone projector, which comprises a convex lens (1), a plane mirror (2), a mobile phone placement part (3) and a pulling focus length adjusting device (4). Through a pinhole imaging principle based mobile phone projector, the convenience of film watching is improved by using the method provided by the invention, and special experience is enhanced. According to the invention, a mobile phone is placed in an inner box, the position of the inner box is adjusted, a bracket is pulled up so as to adjust the angle, and an image reflected by the plane mirror (2) is enabled to form a positively amplified real image after passing through the convex lens (1), thereby achieving effects of a projector. The DIY simple mobile phone projector does not need to draw support from electronic equipment of any load, amplification for a screen of the mobile phone can be realized by only do-it-yourself fabrication, and the operation is freer, simpler and more convenient. The DIY simple mobile phone projector can be applied to occasions of outward camping, mobile phone film watching and the like, and shortens the distance between people.
Description
technical field [0001] The invention relates to a projector, in particular to a DIY simple mobile phone projector. Background technique [0002] Nowadays, with the intelligence and popularization of mobile phones, it has become a common phenomenon to use mobile phones to download colorful movies so as to watch them in leisure time outside. Just imagine that when three or five people gather together to watch a movie while camping outside, what they face is only a palm-sized screen, which is bound to be quite inconvenient. trouble. [0003] If a plate with a small hole is used to block the screen and the object, an inverted image of the object will be formed on the screen. We call this phenomenon small hole imaging. Move the middle plate back and forth, and the size of the image will change accordingly. This phenomenon reflects the property that light travels in a straight line. The size of the image and the object: When the object distance (the distance between the object...
