Abstract

PURPOSE:To integrate a video and a sound by arranging a speaker provided with a diaphragm on which the same reflecting layer as the screen is formed on a certain part of the screen surface. CONSTITUTION:The speaker provided with the diaphragm 7 having a light reflecting layer 9 formed on the surface of it can be formed is arranged in the notched part of the screen and also, arranged on the same plane as the screen. The speaker having the light reflecting layer 9 formed on the surface of the diaphragm is arranged on the same plane on the screen as the reflecting layer 9 of the screen, so that the video can be integrally projected by the screen and the reflecting layer on the surface of the diaphragm without setting the speaker outside the screen, thus, the saving of the space can be accomplished and also, the sound and the video can be integrated as compared with a conventional AV system.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen for displaying enlarged images using a video projector or the like.

0002

2. Description of the Related Art In recent years, television screens have become larger, and it has become possible to enjoy movies on a large screen and with powerful sound even at home. In addition, video projectors that allow you to easily enjoy larger screens are becoming popular in general households. Conventionally, AV systems project images from a video projector onto a screen placed in the front, and speakers are placed next to or below the screen. is common. An example of the above-mentioned screen will be described below with reference to the drawings.

FIG. 2 shows a schematic diagram of a conventional screen. In FIG. 2, 1 is a screen, 2 is a frame that holds the screen 1, 3 is a speaker system installed on both sides of the screen 1, 4 is a video projector, and 5 is an image light. With the above system, images are projected on the screen 1 and transmitted to the viewer, and sound is transmitted to the viewer from the speaker system 3 installed on the side of the screen.

[Problems to be Solved by the Invention] However, in the above-mentioned configuration, since the speakers are installed in a separate location from the screen, a large space is required, and in locations with spatial restrictions, the area of the screen must be reduced. I can't do it. Another drawback was that the sound source was located outside the screen, making it impossible to achieve a true sense of unity between image and sound.

[0005] In view of the above-mentioned problems, the present invention aims to save space in an AV system by disposing a speaker having the same reflective layer as the screen on a part of the screen surface, and also to improve image and audio performance. This makes it possible to integrate the following.

[0006]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the screen of the present invention is provided with a circular or square cutout in a part of the screen surface so that the screen surface and the diaphragm surface are substantially flush with each other. The speaker is provided so that the diaphragm is planar, and a reflective layer similar to the reflective layer of the screen is provided on the surface of the diaphragm.

[0007]

[Function] With the above configuration, there is no need to install the screen and speakers in separate locations unlike in conventional AV systems using screens, and the speakers, which are the sound source, can be installed on the same surface as the screen surface. In addition to saving space, it also makes it possible to integrate the sound source and video.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic cross-sectional view of a screen in an embodiment of the present invention. (Fig. 1), 6 is a screen base material, 7 is a diaphragm disposed in a notch of the screen on the same plane as the screen surface, 8 is a drive unit for driving the diaphragm 7, and 9 is a screen base. This is a light reflecting layer (a layer coated with glass microspheres that strongly reflect light in the direction of incidence) provided on the surface of the material 6.

In the screen constructed as described above, the diaphragm 7 having the light reflecting layer 9 formed on its surface is provided on the same plane as the reflecting layer 9 of the screen, so that the speaker can be installed outside the screen. Moreover, since the image is projected as one by the reflective layer on the surface of the screen and the diaphragm, it is possible to save space and integrate audio and images compared to conventional AV systems. The reflective layer 9 is not limited to glass microspheres as used in this embodiment, but any commonly used screen material may be used, such as an Al vapor deposited layer or a white polymer sheet. Further, the size and shape of the diaphragm 7 can be freely changed depending on the acoustic characteristics to be reproduced, and it is also possible to provide a plurality of diaphragms 7.

[0011]

As described above, according to the present invention, by cutting out a part of the screen and arranging therein a diaphragm having the same reflective layer as the screen, a large speaker can be installed separately from the screen. Since it is possible to provide video and audio without installing a AV system, you can enjoy powerful video and audio without taking up much space even on a large screen, and it takes up significantly less space than conventional AV systems. It is possible. Furthermore, by changing the notch in the screen, the position of the sound source can be changed freely.

Claims (1)

[Claims] 1. A plurality of circular or rectangular notches are provided in a part of the screen surface, and a speaker is disposed in the notch so that the screen surface and the diaphragm surface are substantially flush with each other, and the A screen characterized in that the diaphragm of the speaker is flat, and a reflective layer having the same structure as the reflective layer of the screen is provided on the surface of the diaphragm.
