Abstract

PURPOSE:To obtain an effect generating sound from a picture and to reduce a space occupied by a screen and a speaker system by forming a screen plate unitedly with a speaker box. CONSTITUTION:The titled device is constituted of the screen plate 1 obtained by adhering air permeable and sound passing white cloth or cloth to which aluminium is evaporated in vacuum to a frame body corresponding to the size of a projected picture of a slide projector or the like by applying tensile force to prevent the cloth from being loosened and the speaker box 2 having a picture frame-like frame arranged on the back of the screen plate 1 so as to store the screen plate 1 in its inside and incorporating a speaker in a box having the same external size as that of the frame and thin depth and these parts 1, 2 are united with each other so that sound is generated from a picture at the sound generation synchronized with picture projection. It is also available to constitute a screen plate by separating the frame from the speaker box part 2 as an independent frame and adhering cloth to the back of the frame with tensile force.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a screen device for projecting images such as a video projector, 18 mm projector, slide projector, etc.

Conventional configurations and their problems Video projectors - The screens of 18 mm projectors, slide projectors, etc. are often made of non-porous paper or resin plates whose surfaces are treated with aluminum foil, etc. In addition to the screen, a speaker system is placed around it to produce sound in conjunction with the images. In this case, there is little sense of sound coming from the image itself projected on the screen. There is also a cloth screen, but it is a hanging curtain type, and in this case it is possible to place a speaker system behind the screen, but the sound pressure emitted from the speakers will cause the screen surface to shake. In addition, in any of these conventional configurations, the screen and speaker system are separate, requiring a large installation space, and the interior of the room is not cohesive.

OBJECTS OF THE INVENTION The present invention solves the problems of the prior art and provides a screen device that provides the effect of emitting sound directly from the image projected on the screen, and that is also beautifully arranged as a compact interior.

Structure of the Invention The present invention is a video projector (18 mm projector, slide projector, etc.) in which the frame of the projection screen hole is made of breathable, sound-permeable white cloth, or a cloth whose surface is vacuum-deposited with aluminum so that the cloth does not sag. A screen board for projecting an image pasted under such tension, and a picture frame-like frame arranged behind the screen board so as to house the screen board, and having the same outer diameter as the picture frame-like frame. It consists of a speaker box part with a speaker built into a box with a shallow depth dimension, and is characterized by being integrated so that when an image is captured and sound is generated at the same time, the sound is emitted from the screen. screen device
Also, the frame-like frame can be used as a speaker box part.
, 1. It is also possible to form a frame-like frame with no half-cuts, and by applying tension to the rear part of the frame, it is possible to attach the cloth to form a screen board. Furthermore, the speaker box section can also be used as a screen device that can reproduce stereo sound by dividing the inside of the box into left and right halves and installing speakers in each half. Furthermore, the screen board and speaker box are integrated and thin, making it possible to install them on indoor walls.

DESCRIPTION OF THE EMBODIMENTS FIG. 1 is a diagram showing the appearance of the present invention. Reference numeral 1 shows a screen plate in which white or aluminum vacuum-adhesive cloth is attached under tension to the frame of the projection screen hole. 2 indicates a speaker box portion having a frame-like frame. Figure 2 shows the screen board and speaker box part separated.
It shows a state in which the fabric 1b is attached under tension to the 1λ frame. Reference numeral 2a indicates a frame-like frame, and reference numeral 2b indicates a speaker attached to the speaker box section of 2.

Figure 3 shows an embodiment of the pond according to the present invention, and 3 shows a screen board with a cloth attached directly to the rear of the picture frame.
) 4 indicates the speaker box section placed behind it. FIG. 4 is a sectional view of a room showing an example of the use of the present invention, in which the screen of a video projector 5 suspended from the ceiling is reflected on a screen device attached to a wall 6.

Effects of the Invention The screen device of the present invention compactly integrates the screen plate and the speaker box to obtain the effect of emitting sound from the image, and at the same time has a frame-like frame. Therefore, even if it is attached to the wall of a room, it can become part of the interior of the room without detracting from its aesthetic appearance.

Furthermore, the space occupied by the screen and speaker stem can be greatly reduced compared to the conventional example.
