Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a speaker net installed in a speaker cabinet.

Conventional technology In the past, speaker nets attached to speakers were often made of a square wooden frame covered with cloth, and were attached to protect the vibrating surface of the speaker and for design purposes. It had no function. In recent years, with the arrival of the AV era, video projectors such as so-called video projectors, which are devices that enlarge images onto a large screen and enjoy images with great impact, have become popular. There are two types of video projector systems for projecting images onto a screen: a transmissive screen system and a reflective screen system, and the present invention relates to the latter system. Conventionally, the image projected by a video projector is reflected and projected onto a screen placed in the front, but for audio, a speaker equipped with a speaker net is often placed behind or to the side of the screen, which is completely separate from the NuClean. The speaker net attached to the conventional speaker mentioned above will be explained below with reference to the drawings.

FIG. 8 is a perspective view of a conventional speaker net.

In FIG. 8, 2 is a speaker net frame, 3 is a speaker cabinet, 4 is a mounting holder for attaching the speaker net frame 2 to the speaker cabinet 3, 5 is a speaker unit, and 6 is a speaker net. The operation of the speaker net attached to the speaker configured as above will be explained below. The sound waves emitted from the speaker unit 5 are radiated forward through the speaker net 6. At this time, the speaker net 6 is designed to have a high aperture ratio as much as possible so as not to affect the acoustic characteristics, and the speaker unit However, in the above configuration, a screen for projecting the image from the projector is required separately from the speaker, which requires a large space.
When trying to arrange speakers and a screen in a limited space, there are problems such as the screen becoming smaller.

In view of the above problems, the present invention provides a speaker net that can save space and easily increase the screen area.

Means for Solving the Problems To achieve this object, the speaker net of the present invention has the following features:
It has a configuration in which a screen for projecting an image from an image projector is stretched over a speaker net frame at a constant distance from the speaker unit on the front side of a housing having a speaker unit.

Effects of the present invention The above-described configuration makes it possible to project an image from a projector onto the speaker system itself, which eliminates the need to prepare a separate screen and speaker system as in the past, and saves space. This is something that can be achieved. Furthermore, by stacking a plurality of speaker cabinets and joining the speaker nets together, a large screen can be easily realized as it can be specified to any size.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a spica net in a first embodiment of the present invention. In FIG. 1, 1 is a screen, and 2, 3, and 4.5 are a speaker net frame, a speaker cabinet, a mounting holder, and a speaker unit, respectively. The speaker net configured as above will be explained. First, sound is emitted from the speaker unit 6 and reaches the listener, and at the same time, an image from the image projector is projected onto the screen 1.

As described above, according to this embodiment, since the speaker net attached to the speaker also serves as a screen, a large screen image and sound output can be obtained without installing the screen and speakers separately. Space-saving yet powerful images.

Voice is something that can be realized. In the first embodiment, the screen used was a polyvinyl chloride sheet whose surface was processed and A4 coated as a reflective surface.
Any structure, material, or processing may be used as long as the screen is bright and the viewing angle is wide, and there are no limitations on the material of the screen. It goes without saying that the size of the screen can also be changed freely, just like the size of the speakers.

In addition, in the first embodiment, 7 ・＼ shown in FIG.
-7, the speaker net also serves as a screen, its size is equal to or larger than the surface facing the screen of the speaker cabinet 3, and the screen surface is made flat, as shown in Figure 3. By stacking a plurality of speaker cabinets 3, a large screen integrated with speakers can be easily realized. Although four speaker cabinets 3 are stacked in this embodiment, it is also possible to freely stack and use as many speaker cabinets as needed.

FIG. 4 is a perspective view of essential parts of a speaker net showing a second embodiment of the present invention. In Figure 4, 1 is a screen;
2 is a speaker net frame whose size is equal to or larger than that of the cabinet, and 7 is a tape made of the same material as the screen 1 or having the same light reflection characteristics. When a plurality of speaker nets on which the screen 1 is stretched are joined together to form a large-area screen, even if there is a slight gap between the speaker nets, it will be seen as a seam. By pasting the seams with tape made of the same material as the screen material or with tape having the same light-reflecting properties, it is possible to make the screen larger so that the seams are invisible.

Note that in the second embodiment, a tape made of the same material as the screen or having the same light-reflecting properties as the screen was used as the tape attached to the seam of the screen, but this tape does not reflect light on the surface and is transparent. You may do so. An example of this tape is a film made of acrylic resin, which has excellent optical properties and is used in plastic lenses, etc.
Surface treatment (Mg F 2 ,
S102.

Examples include those in which A12o3 or the like is formed on the surface by a multilayer coating for antireflection, which is commonly used in ordinary lenses, such as vacuum evaporation or ion blating.

FIG. 6 is a perspective view of essential parts of a speaker net showing a third embodiment of the present invention. In Fig. 5, 1 is a screen cut with a taper 14 at the side end, 2 is a speaker net frame, and 7 is a screen cut with a side end tapered opposite to screen 1. This tape connects the speaker net. As described above, according to the third embodiment, the cross-sectional shape of the tape connecting the speaker net has a taper 8 in the thickness direction, and the end of the screen 1 of the speaker net has a taper 8 opposite to the tape 7. By having a taper 8 and joining the screen and tape at the tapered portion, the screen 1. It is possible to join them together to form a large screen with no visible seams. Here, it is desirable to use a material for the tape 7 that connects the screen 1 with a material that has the same or approximately the same light reflection characteristics as the screen 1.

FIG. 6 is a perspective view of a main part of a speaker net showing a fourth embodiment of the present invention. In Figure 6, 1 is screen 2
