Abstract
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
The present invention is a kind of projector, relates to a kind of DIY simple mobile phone projector specifically.
Background technology
Nowadays along with the intellectuality of mobile phone is with universal, the film utilizing mobile phone-downloaded colorful in case outside the leisure time view and admire and become a kind of universal phenomenon.Just think when camping outside, three or five people gather together viewing film time faced by the screen that just a palm is large, must seem rather inconvenience, thus associates the simple machine utilizing a pinhole imaging system principle design similar projection instrument, solve such worry.
Block between screen and thing with a foraminate plate of band, will the inverted image of formation on screen, we such phenomenon pinhole imaging system.Plate in the middle of movable, as size also can change thereupon.This phenomenon reflects the character that light is linearly propagated.Picture and the size of thing: when object distance (distance of thing and aperture) equals image distance (distance as with thing), as with thing etc. greatly.When object distance is less than image distance, as being greater than thing.When object distance is greater than image distance, as being less than thing.Around this principle, mobile phone can be placed on aperture by us, and the constantly position at adjustment mobile phone place and angle, the content imaging so on mobile phone screen naturally also can be amplified thereupon or reduce, thus reaches the effect of projector.
The online DIY projector existed mainly utilizes some electronic equipments at present, as ballast resistor liquid crystal display etc., although drop shadow effect is fine, but manufacturing process is rather loaded down with trivial details, can not be that most people is used, and consider to be inconvenient to carry from volume mass, so the requirement of most people can not be met.Front projector: a kind of front projector, comprises image forming apparatus, this image forming apparatus generates an image according to the display of input.Projecting lens projects this image, to obtain projects images in view field.At least one light source generates at least one beam ring border light beam, and they are projected via described same projecting lens, thus obtains the ambient-light images being positioned at described projects images both sides at least in part.In addition, also someone utilizes simple aperture box directly to project, but effect is not satisfactory.Mainly because light is assembled not, cause picture unintelligible.
The to sum up consideration of three, I, from simple and easy angle of laying equal stress on effect, selects with the simplest principle, i.e. pinhole imaging system principle, makes simple projector, to meet most of Man's Demands.Its advantage is simple and easy convenient but effect pretty good, and manufacturing process facilitates easy to learn.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, provide the problem of the too small viewing inconvenience caused of a kind of mobile phone screen.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
The present invention includes: convex lens 1, level crossing 2, mobile phone lay down location 3, pull and focalize 4.The present invention is realized by following steps:
Step (1): utilize the aperture in convex lens replacement pinhole imaging system, thus realize gathering of light;
Step (2): inside and outside two boxes, outer box ensures that light does not leak, and inner box can holding mobile telephone, and can change position focusing;
Step (3) a: level crossing is placed at inner box place, ensures that imaging is not reverse;
Step (4): interior box support, adjustment angle.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is without the need to the electronic equipment by any load, as long as do it yourself to make, just can realize the amplification to mobile phone screen, operation is more freely easy.Can be applicable to long camping trip, the occasions such as mobile phone viewing, promote interpersonal distance.
Accompanying drawing explanation
Fig. 1 is the model operating diagram of DIY simple mobile phone projector.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
The present invention includes: convex lens 1, level crossing 2, mobile phone lay down location 3, pull and focalize 4.By a kind of Mobile phone projector based on pinhole imaging system principle, improve the convenience of viewing in this way, strengthen and experience especially.Mobile phone is placed in inner box, adjustment inner box position, draws high support adjustment angle, make the picture of flat mirror reflects, after convex lens, form the reality that front is amplified, thus reach the effect of projector.
The undeclared part related in the present invention is same as the prior art or adopt prior art to be realized.
Claims (3)
1. a DIY simple mobile phone projector, comprising: convex lens (1), level crossing (2), mobile phone lay down location (3), pull focalize (4), it is characterized in that: described easy to learn without the need to making with operating process described in any electronic equipment.
2. according to claim 1 without the need to electronic equipment, it is characterized in that: utilize simple and easy material carton, level crossing, convex lens etc.
3. making according to claim 1 and simple to operate easy to learn, is characterized in that: as long as utilize the adjustment of focal length and the reflected refraction of level crossing convex lens, just can realize the amplification of mobile telephone image.
