Description

Multimedia projector for large wall screen of household cinema appliance

The present invention relates to a kind of field of home theater wall projection arrangement technology, especially home theater changes that people need not see TV but the apparatus system of seeing a kind of large wall screen multimedia overhead projector of electric projection.

Home theater is as the term suggests be that cinema is moved back to a high-tech video display subject in the family.The binomial function of cinema's maximum is " shadow " (wide screen) and " sound " (sound system); So-called " seeing a film " is based on " seeing " (seeing image), and it is auxilliary listening " sound ".In like manner, home theater also is based on " seeing image ".It is condition that home theater worthy of the name must meet above two big functions, and it is indispensable to coordinate mutually." image " in the home theater is the primary; " sound equipment " is secondary.But existing home theater is qualified, only met secondary " sound equipment " this condition (the combination audio effect of five covers, seven covers can be identical with cinema), and this condition of the most primary primary " image " is not met so far.Why not does the producer that problem just goes out at home theater move into cinematographic projector in the cinema and wide screen in the home theater to come? at present, player in the home theater and screen unite two into one and serve as with television set (screen), because the area of television screen has only 1/80 of the wide area of cinema's silver, so " image " effect of home theater is very poor, though large-screen television projector comes out, but because volume is big, deal is heavy, cost an arm and a leg, the big more image of television set is unintelligible more, therefore can not become the focus of consumption.Crux and basic outlet that the present invention attracts to consume sound and universal home theater are the wide of the home wall wide screen image and the visual field and shake! The guide consumption person breaks the traditional habit of " having seen TV " with television set since half a century, changes in home theater and " sees electric projection "! " electric projection " is that home theater is broken through the new subject that television set is changed, key is the variation of the purposes generation matter of the structure of home theater and television set, the structure of home theater is reassembled into the device of a complete projection and sound system, reaches the dual new purpose of shaking effect of home theater and cinema phonotape and videotape.Science of the present invention is that television set no longer is that the appreciator is used for the direct tool of " see TV, " vision imaging, but as the medium (leading role becomes the supporting role) that are used for sending multimedia image signal and light emitting source in the home theater projection player, the film copy (film) that is equivalent in the cinematographic projector equally uses, and the appreciator sees will be on the wall on the large-screen " electric projection "! Place oneself in the midst of the boundary of shaking of cinema's image sound equipment double effects seemingly! Its home theater looks and purpose worthy of the name also.

The purpose of this invention is to provide a kind of multimedia projector for large wall screen of household cinema appliance, design a kind of multimedia projector system that national conditions are popularized China's large wall screen of household cinema appliance that meets.

For reaching this purpose, the object of the present invention is achieved like this:

On the basis of home theater structure member (former three-major-items: television set, video disc player and combination sound box), increase a projection player again, a wall lastblock large-screen and a micro-television set (former television set can utilize), be combined into the household audio and video system of a complete projection and sound equipment, reach and the dual effect of shaking of cinema's phonotape and videotape.

Be converted into the micro-television set cost by original medium-sized television set and can save 50%, be used for acquiring home theater projection player and large wall screen, cost can maintain an equal level basically, helps popularizing.

The shape of the parts that home theater increases newly, structure, technical characterictic:

(1) structure, the manufacture craft of the projection player of home theater, it is so huge, expensive that cost can not resemble professional video arcades, can not resemble again need copy and tumbler the cinema film projector.And the purpose of the player of home theater needs only the image projection of micro-television set fluorescent screen to the large-screen of wall, amplifies (erect image), affords a wide field of vision, and clear picture promptly reaches.Put into practice verifiedly, people are consistent to generally acknowledge that the image on the film wide screen is the most clear, and vision is the most comfortable.The present invention adopts environmental protection digitizing function type micro-television set (the more little image of television set is clear more) screen image technical characterictic the most clearly, is applied on the home theater projection arrangement.Therefore the image effect of projection gained reaches the effect of shaking of 100% cinema's wide screen image.The shape of family's projection player was configured to for five most of compositions the spitting image of cinematographic projector: (A) gantry base, can be made into portable style, and be placed on desk or the audio-video framework; Style is fixed, is fixed on the wall with the large wall screen opposite or unsettled below ceiling.The base top is contained in convex lens, rotatable portable focal length of convex lens regulating sleeve, iodine-tungsten lamp light emitting source, shading guard shield and 5 main members of environmental protection digitizing function type micro-television set.The base below is audio-video combo box, the interior video disc player etc. of putting.(B) convex lens and rotatable portable focal length of convex lens regulating sleeve.The diameter of convex lens will be decided by the size of room and television screen size and produce different specifications.(C) by stand upside down (D) the iodine-tungsten lamp light emitting source (economizing galvanoluminescence formula bulb) of environmental protection digitizing function type micro-television set (or the existing television set of family) of (fuselage) of fixed placement on the position of original cinematographic projector dress film copy.Be contained on the appropriate location between television screen and the convex lens, (F) light shield protects.The making basic principle of home theater projection player is identical with cinematographic projector, all is to use the imaging of lens refracted ray the real image principle of the amplification that becomes to stand upside down when f＜u＜2f.Different essential distinctions is that cinematographic projector uses is film copy (function singleness), the micro-television set in the home theater projection player then comes to substitute " film copy " (multi-functional)

(2) large wall screen, adopt the three technology scheme, select wherein one for the consumer: (A) in bedroom or parlor, select the long wall of one side, be used as the large wall screen (being equivalent to a wide screen in the cinema) that projection is used, be named as " paint for wall large-screen ".Manufacture method: smearing whitewash (adopting black-bottom paint and special crystallofluorescence powder bilayer technology) on the monoblock wall.Its technical characterictic: make the color of large-screen more bright-coloured, become clear, can reproduce high quality image with stereovision, when crystal light powder is subjected to the external light irradiation, only reflect the light identical with the crystallofluorescence powder, absorb the light with its different colours, improved the purity of picture color thus greatly.(B) (specification is: 3200 * 1400mm or the like) to hang a large wall screen identical with cinema wide screen material on wall.(C) hyperplane glass screen, area size: 3200 * 1400 * 8mm).A best monoblock is fixed on the wall (also can be cut into two).Manufacturing materials adopts 100% hyperplane glass, special crystallofluorescence powder, not reflective material, the peculiar top layer of screen diffuse surface.Its technical characterictic is: the visual field area of hyperplane glass screen is 25 times of general television set fluorescent screen area (large-screen television projector fluorescent screen areas 10 times); Be equivalent to 1/3 or 2/5 of cinema's wide screen area.In the bedroom, load onto the hyperplane glass screen, the luxurious style that seems, as long as remote controller one by, the All Around The World picture has a panoramic view.Under indoor normal light, also can enjoy life-like bright image, stay the scene seemingly, large-screen can not resemble the piece large mirror, and with near object, even the audience is reflected on the picture, and order is viewed and admired to enjoy and is greatly affected.
