Description

The utility model relates to film and video display devices used during mass and entertainment events, seminars, symposia, exhibitions, as well as in the field of commercial, political, social advertising.

A mobile projection-sound complex can be used in four versions: a movie screen, a movie screen with a car, a projection tent, a projection tent with a car.

In the period of the formation and development of Soviet cinematography, film movement was used to perform film screenings in rural settlements. According to the generally accepted definition, cinematography is a portable mobile cinema projection unit for demonstrating mainly narrow-film (16 mm) films. A movie camera kit usually includes: a movie projector, a sound reproducing device, a movie screen, sometimes an autonomous energy source (see. Great Encyclopedic Dictionary). The specified film movement is accepted by us as the closest analogue of the claimed film movement. The disadvantage of the closest analogue is the use of obsolete equipment.

The closest analogue to cinematography with a car is a TV mobile (see http://www.tv-car.ru). The known technical solution has a number of significant drawbacks: the binding of a technical solution to a specific car, which increases the cost, and the dependence of the operation of the entire installation on the technical health of a particular car. Due to the design feature of the TV mobile, it is impossible to use large screens. The claimed technical solution allows you to use any vehicle (truck, car) for the transportation of equipment, there is no need to purchase it with equipment, you can rent it. In cinematography with a car, screens of different sizes can be used.

The third embodiment of the claimed technical solution - the projection tent can be compared with the foreign counterpart - Mobilemedia company "Reversa" (see http://www.reversa.ru). Both the analogue and the projection tent have similar essential features with the exception of the boxa tent structure. The closest analogue uses a trailer that is not disassembled, but transported as a trailer. This involves large storage areas for Mobilemedia. In addition, the screen used has a specific size, and it is smaller than in the claimed technical solution.

The claimed technical solution has a collapsible tent structure, which allows it to be transported compactly and stored in small areas. Screen size may vary depending on the dimensions of the tent structure.

The fourth version of the proposed technical solution - a projection tent with a car, according to our information, has no Russian and foreign analogues. The closest analogue is the Mobilemedia company Reversa (see http://www.reversa.ru).

The claimed technical solution has a collapsible tent structure, which allows it to be transported compactly and stored in small areas. Screen size may vary depending on the dimensions of the tent structure.

In the claimed technical solution, the car interior is used to operate the installation at low temperatures.

The technical result consists in obtaining high-quality video on a large screen with high-quality sound in rooms and / or in the open area through the use of multimedia and sound equipment.

A mobile projection-sound complex is proposed, which can be used in four versions: motion picture, motion picture with a car, projection tent, projection tent with a car.

The film transfer includes a screen, a projector, a signal source, a current source, and switching tools. Unlike the closest analogue, it includes an audio and video signal source, sound amplifier kit, mixer, microphone, projection table, uninterruptible power supply.

Moving a car includes a vehicle.

The projection tent includes a rear projection screen, a projection table, an audio and video signal source, a sound reinforcement kit, a mixing console, an uninterruptible power supply, a current source, and switching equipment. Unlike the closest analogue, all equipment is located inside an independently standing collapsible tent structure, one of the walls of which is a screen, and the vehicle is a car or truck.

The projection tent with a car includes a vehicle.
