bridge them. The connection portion 316 is susceptible to the vibration of the woofer unit 40
because it is connected to the support column 32 or located near the woofer unit 40. For this
reason, as shown in FIG. 8, the rib 318 is provided so as to bridge the connection portion 316 so
that the structure of the woofer unit 40 is not easily affected by the vibration.
[0034]
Further, as shown in FIG. 7, the upper portion 313 of the stand rear cover 31 is configured to
have a hole 319 at a position where it is screwed to the support 32 by a screw 311 or the like.
The stand rear cover 31 and the column 32 are connected by the screw 311 or the like.
[0035]
In the present embodiment, as shown in FIG. 4, the stand rear cover 31 is screwed to the support
32 at five places by means of screws 311 or the like.
However, the position where the stand rear cover 31 is screwed to the column 32 and the
number of the screws 311 and the like are not particularly limited, and the stand rear cover 31 is
screwed to the column 32 with any position and any number of screws 311 and the like. It is
possible.
[0036]
Further, in FIG. 7, a rib 318 is provided so as to bridge the two connection portions 316 provided
above the back surface 314, and the rib 318 is provided so as to bridge the two connection
portions 316 provided below the back surface 314. I decided to set it up. However, it is also
possible to provide the rib 318 so as to bridge the connection portion 316 provided above the
back surface 314 and the connection portion 316 provided below the back surface 314. Even
with such a configuration, the rigidity of the stand rear cover 31 can be enhanced, and vibration
due to the sound output from the woofer unit 40 can be resisted.
[0037]
The stand rear cover 31 of this embodiment has a hole 312 in the upper portion 313 of the
03-05-2019
10
stand rear cover 31 as shown in FIG. 4, and the sound output from the woofer unit 40 provided
outside the column 32 is a hole 312. I am trying to escape from the outside. Specifically, the
sound output from the woofer unit 40 temporarily proceeds toward the back surface 314 of the
stand rear cover 31, and the traveling direction (directivity) of the sound changes on the back
surface 314 of the stand rear cover 31. It is outputted to the outside from the hole 312 provided
in the upper part 313. Thereby, the stand rear cover 31 can change the directivity of the sound
output from the woofer unit 40, and can output the changed sound to the outside.
[0038]
In the stand 30 of the present embodiment, the rotation mechanism 321 is provided inside the
column 32, and the column 32 provided on the stand base 34 by the rotation mechanism 321, as
shown in FIGS. 6 (a) and 6 (b). The rotation angle of can be changed arbitrarily. For this reason,
in the stand 30 of the present embodiment, the position environment of the woofer unit 40
provided outside the post 32 is different according to the rotation angle of the post 32. As a
result, when there is no stand rear cover 31, as shown in FIGS. 9A and 9B, the directivity of the
sound output from the woofer unit 40 also fluctuates according to the rotation angle of the
support 32, As a result, the acoustic environment of the sound output from the woofer unit 40
changes according to the rotation angle of the support column 32. FIG. 9A shows a state in which
the support 32 is rotated to the left by the rotation mechanism 321, and FIG. 9B shows a state in
which the support 32 is rotated to the right by the rotation mechanism 321.
[0039]
Therefore, as shown in FIG. 3 and FIG. 4, the stand 30 of the present embodiment screws the
stand rear cover 31 to the post 32 so as to cover the entire woofer unit 40 and stands the sound
output from the woofer unit 40 It is made to escape from the hole 312 provided in the upper
portion 313 of the rear cover 31 to the outside. Thereby, even if the position environment of the
woofer unit 40 differs according to the rotation angle of the support 32, the sound output from
the woofer unit 40 is always escaped from the upper side to the outside, and the directivity of the
sound output from the woofer unit 40 is It makes it possible to reduce sexual fluctuations. As a
result, the stand 30 of the present embodiment can reduce the variation in the acoustic
environment of the sound output from the woofer unit 40 provided outside the support column
32. Further, as shown in FIGS. 3 and 4, the die cast 36 or the woofer unit is fixed by screwing the
stand rear cover 31 to the post 32 so as to cover all the die cast 36 or the woofer unit 40
attached to the post 32. As well as protecting the 40 and the like, it is possible to prevent the die
cast 36 and the woofer unit 40 and the like from being exposed to the outside. As a result, the
03-05-2019
11
product protection of the stand 30 can be achieved, and the stand 30 excellent in design can be
configured.
[0040]
FIG. 10 is a side view of the display device 10 in a state where the stand rear cover 31 of the
display device 10 shown in FIG. 3 is removed. FIG. 11 is a rear view of the display device 10
shown in FIG.
[0041]
Although the woofer unit 40 and the die cast 36 are joined by the attachment portion 362
provided on the die cast 36 and the screwing portion 38 provided in a projecting manner on the
woofer unit 40, the woofer unit 40 is provided in a projecting manner A damper rubber 37 is set
on the screwing portion 38. The damper rubber 37 will be described later.
[0042]
The woofer unit 40 is attached to the die cast 36 by four attachment parts 362 with respect to
the screw part 38, as shown in FIG. In the present embodiment, the reason for attaching the
woofer unit 40 to the four places shown in FIG. 11 is that the strength and balance are excellent
in consideration of the power of the woofer unit 40. However, the place where the woofer unit
40 is attached to the die cast 36 is not limited to the four places shown in FIG. 11, but it may be
configured to attach at any number of places.
[0043]
In FIG. 11, two screwing portions 38 are respectively provided on the upper and lower sides of
the woofer unit 40, and the woofer unit 40 is attached to the die cast 36 by four attaching

[0045]
The die cast 36 is made of sheet metal such as aluminum or iron.
[0046]
Although the woofer unit 40 can be attached to the support 32 without the die cast 36, the
woofer unit 40 requires a predetermined strength for the support 32 because of its weight.
If the column 32 does not have a predetermined strength, the entire display device 10 vibrates
due to the vibration based on the woofer unit 40.
For this reason, in the present embodiment, a die cast 36 is attached to the column 32, and the
die cast 36 produces strength in the column 32, thereby reducing the transmission of the
vibration based on the woofer unit 40 to the display unit 20. When the die cast 36 is made of a
material such as plastic, the required strength for the column 32 can not be generated, and as a
result, the die cast 36 and the column 32 vibrate together, and the woofer unit 40 Vibration
based on will be amplified further. For this reason, the die cast 36 is preferably made of a
material such as aluminum or iron, not a material such as plastic.
[0047]
Further, the die cast 36 is provided with a hole 361, and the post 32 and the stand rear cover 31

rear cover 31 is provided directly on the die cast 36, or provided on the outer peripheral portion
of the column 32 on which the die cast 36 is not provided. You can also However, when the
stand rear cover 31 is provided directly on the die cast 36, the vibration of the die cast 36 is
directly transmitted to the stand rear cover 31, and the stand rear cover 31 vibrates. Further,
when the stand rear cover 31 is provided on the outer peripheral portion of the column 32
where the die cast 36 is not provided, it is possible to prevent the vibration of the die cast 36
from being directly transmitted to the stand rear cover 31. The connection strength of the central
