However, although the conventional screen speaker device can be used as a screen, there has
been a problem that the components constituting the screen speaker device can not be freely
recombined, and therefore can not be used in a desired shape.
[0006]
For example, in the conventional screen speaker apparatus, it is difficult for the user to freely
arrange a plurality of wall materials (vibration materials) in the vertical or horizontal direction or
to change the thickness or the shape of the wall material freely.
Therefore, the conventional screen speaker device has only played a role as a screen having no
functionality only as a blindfold or a soundproof.
[0007]
In addition, when focusing on the function as a speaker, according to the vibration theory, if a
vibrating thing is hit against a certain thing, a sound always sounds, but for example, a vibrating
thing is a vibrator, and a touching thing is a vibrating material When, in the thin flat speaker
device disclosed in Japanese Patent Application Laid-Open No. 2004-64726, a vibrator is
attached to one vibrating member in the free-standing flat speaker device, the vibrator 1 is used
to output sound. It was not possible to say that only the vibration characteristic due to the sheet
could be obtained and voice in a wide frequency band was output.
[0008]
The present invention has been made in view of such a situation, in which a vibrating material is
disposed with many degrees of freedom so that sound in a wide frequency band can be output.

[0110]
FIG. 17 shows a view of a room 151 in which a wall is constituted by a plurality of screen
speaker devices 11 as viewed from the upper side.
[0111]
In the room 151, the walls surrounding the four sides are constituted by walls 161-1 to 161-12
having the same function and configuration as the screen speaker device 11 (FIG. 1), for example.
That is, since FIG. 17 is a view from the upper side, it is expressed that the walls 161-1 to 161-12
are connected in the horizontal direction, but in fact, it vibrates in the vertical direction as well.
The plates are connected, and the number of diaphragms and vibrators is arbitrary.
[0112]
In the example of FIG. 17, the room 151 has four surfaces: walls 161-1 to 161-3, walls 161-4 to
161-6, walls 161-7 to 161-9, and walls 161-10 to 161-12. It is composed of

23
Each of the walls 161-1 to 161-12 plays a role as a screen (wall) at the same time as the function
of the speaker as the screen speaker device 11 does.
That is, as in the case of the screen speaker device 11, each of the walls 161-1 to 161-12 causes
various sounds to be output by increasing the vibrating material in the vertical direction or
adjusting the thickness of the vibrating material. Can.
[0114]
Thus, in the room 151, the walls 161-1 to 161-12 having the same function and configuration as
the screen speaker device 11 are installed with more freedom, and the vibration material is
disposed to reduce the frequency It is possible to output voice in a wide frequency band up to
high frequencies.
[0115]
Although the room 151 is described as being surrounded by four faces in the example of FIG. 17,
the present invention is not limited to the four faces, and at least one face may be provided.
In addition, although one surface is described as being constituted by three walls (for example,
walls 161-1 to 161-3), in the present invention, not only three walls but at least one wall (one
wall) For example, the wall 161-1) may be provided.
[0116]
Further, instead of the vibrating member 31, for example, a wall member of a predetermined
shape, a thin television receiver using an LCD (Liquid Crystal Display), or the like may be fixed to
the screen speaker device 11.

FIG. 18 is a diagram showing a screen speaker apparatus 211 according to still another
embodiment of the present invention.
[0118]
In FIG. 18, the same parts as those in FIG. 1 are denoted by the same reference numerals, and the
description thereof will be omitted.
That is, the screen speaker device 211 is provided with a screen 221 instead of the diaphragm
31-2 provided in the screen speaker device 11 of FIG.
[0119]
The screen speaker device 211 fixes each of the diaphragm 31-1, the screen 221, and the
diaphragm 31-3 in the same manner as the screen speaker device 11.
[0120]
The screen 221 is formed of, for example, a translucent material such as a resin or a white cloth,
and displays an image projected from the projector 231.
Further, in the example of FIG. 18, the projector 231 is described as a rear projector that projects
from the back of the screen 221. However, the screen may be displayed as a front projector that
projects from the front of the screen 221.
[0121]
At this time, since sound can be output from each of the vibration member 31-1 and the
vibration member 31-3, it is possible to output sound according to the image displayed on the
screen 221.
[0122]
When the screen speaker device 211 is formed of a translucent material, for example, when an
image is not displayed on the screen 221 by using a device that becomes translucent (or
11-05-2019
25
transparent) when electricity is passed through. It is also possible to show the view opposite to
the user's position and the opposite side of the room through the translucent screen 221.
[0123]
Further, as described above, since the screen speaker device 211 can detachably fix the vibration
member 31 and the screen 221, for example, the screen 221 can be freely combined in each of
the vertical direction and the horizontal direction to make the An image can be displayed on the
screen of the screen, and the vibration members 31 can be freely combined in each of the
vertical direction and the horizontal direction to output sound in a wider frequency band.
[0124]
As described above, according to the present invention, it is possible to flexibly arrange the
vibrating member with many degrees of freedom, and output voice (voice with a wide dynamic
range) in a wide frequency band from low frequency to high frequency. In addition, the sound
transmission effect can be improved.
[0125]
Further, according to the present invention, since the screen speaker apparatus has a
configuration in which a plurality of vibrating materials having different sizes, materials, or
thicknesses, for example, are attached in the vertical direction, the vibrator is used for each
vibrating material. When it is attached, sound quality can be improved because it is possible to
combine sound of a good frequency band in the vibration characteristics of the vibrating member
than in the case of a single plate vibrating member, and the resonance point of the vibrating
member is suppressed By doing this, it is possible to output a voice without distortion.
[0126]
Further, according to the present invention, since the screen speaker devices can be connected in
the horizontal direction, by changing the material of the vibration material in those screen
speaker devices, sound in the frequency band which is excellent in each screen speaker device
can be obtained. The sound quality can be improved by combining.
[0127]
In the above-mentioned example, although a bolt and a nut were explained as an example as a
fastener which fixes each member such as the main frame 51 and the sub frame 52, the present
invention is not limited thereto and a method capable of fixing each member It may be any as
long as
