The present invention relates to a speaker system. More particularly, the present invention
relates to a speaker system for a large television which is space-saving, easy to connect, and
excellent in sound quality.
[0002]
In recent years, large flat-screen TVs such as plasma TVs and liquid crystal TVs have been
rapidly spreading. As a result, it is considered that the potential demand for a home audio visual
(AV) system (so-called home theater system) using such a large flat screen television is also

rapidly increasing.
[0003]
However, in practice, such home theater systems are not as popular as potential demand. The
reason is (1) there is no installation place of the speaker system for home theater when
considering the housing situation in Japan, (2) connection of each device for the system is
complicated, and wiring after connection is (3) The tall speakers (longitudinal speakers) sold as a
set with large TVs are prone to falling, so there are likely to be many people who dislike the
installation.
[0004]
On the other hand, with a speaker built into a large television, the sound quality is insufficient
compared to that of a large screen image, so movies and sports can not be enjoyed sufficiently.
[0005]
In order to solve the above problems, a television storage rack incorporating a speaker has been
proposed (see Patent Documents 1 and 2).
However, since it is necessary to assemble and complete each unit which accommodated an
amplifier and a speaker, the rack of patent document 1 does not eliminate the complexity of the
connection of each unit (each apparatus) at all. Furthermore, this rack has not been devised at all
for improving the sound quality. Moreover, although the rack of patent document 2 attaches a
speaker to the support member of a rack, and uses the support member as an acoustic pipe, it is
inadequate about the surround effect for home theaters. Furthermore, in this rack, since the
speaker is attached to the support member, the speaker is exposed to the outside, and the
appearance is not excellent. Utility model registration No. 3040883 JP 2004-48168 A
[0006]
As described above, there is a strong demand for a large television speaker system that is easy to

According to the present invention, by arranging the left channel speaker, the right channel
speaker, and the center channel speaker such that the axes of the respective speaker units are
positioned on a straight line in the horizontal direction, an extremely excellent sense of sound
movement is obtained. Can be realized.
Furthermore, since the horizontal base incorporating these speakers not only functions as an
enclosure for these speakers but also serves as a large TV mounting base, the installation space
for TVs and speakers is significantly larger than that of a conventional home theater system. It
can be made smaller.
Furthermore, since the wiring on the speaker side is completed within the horizontal base, the
user need only connect the speaker lead wire to the speaker terminal of the television.
Therefore, the complexity of the connection is also eliminated.
In addition, since most of the wiring on the speaker side is accommodated in the horizontal base
portion, the wiring after connection is not unsightly.

embodiment of the present invention.
FIG. 2 is a front view of the speaker system of FIG.
FIG. 3 is a cross-sectional view of the speaker system of FIG. 1 as viewed from above.
FIG. 4 is a cross-sectional view from above of the speaker system according to a further preferred
embodiment.
The speaker system 100 includes a horizontal base 10 and legs 20 for holding the horizontal
base 10 horizontally. The horizontal base 10 has a left channel speaker 11L, a right channel
speaker 11R, and a center channel speaker 11C. Preferably, the left channel speaker 11L, the
right channel speaker 11R and the center channel speaker 11C each have at least one tweeter
and at least one woofer. In the illustrated example, the left channel speaker 11L and the right
channel speaker 11R each include one tweeter and one woofer. The center channel speaker
comprises a tweeter and two woofers. The type, configuration, and number of units provided in
each speaker can be appropriately selected according to the purpose. If necessary, at least one
duct is provided in at least one of the left channel speaker 11L, the right channel speaker 11R,
and the center channel speaker 11C. By providing the duct, the sound quality of the low range
can be further improved. In the illustrated example, one duct is provided for each of the left
channel speaker 11L, the right channel speaker 11R, and the center channel speaker 11C. The
shape, number, arrangement position, etc. of the ducts can be appropriately selected according to
the purpose.
[0017]
The left channel speaker 11L, the right channel speaker 11R and the center channel speaker 11C
of the horizontal base 10 have their respective speaker unit axes (that is, the centers of the
diaphragms of the tweeter and the woofer) horizontally aligned (one point in FIG. 1) It is
arranged to be located on the dashed line H). By adopting such a configuration, it is possible to
realize a very good feeling of movement of sound. As a result, an excellent surround system can
be realized with a simple configuration.

The horizontal base 10 functions as an enclosure of the left channel speaker 11L, the right
channel speaker 11R, and the center channel speaker 11C. At the same time, the horizontal
support 10 has sufficient characteristics (for example, strength, width, and stability) to become a
large TV support. Since the volume space of the left channel speaker 11L, the right channel
speaker 11R and the center channel speaker 11C becomes large as a result of the horizontal base
10 having a sufficient size for mounting a large television, the sound quality of these speakers is
increased. (In particular, the low region) can be significantly improved.
[0019]
The horizontal mount 10 includes partitions 12 defining volume spaces of the left channel
speaker 11L, the right channel speaker 11R, and the center channel speaker 11C. The partition
wall 12 also functions as a reinforcing member for the horizontal mount 10, and is given
sufficient strength to be a mounting base for a large television. Preferably, as shown in FIG. 3, the
partition wall 12 is provided obliquely to the axial direction of the speaker. By adopting such a
configuration, the occurrence of standing waves can be reduced. The angle defined by the
partition wall 12 and the axial direction of the speaker (displacement in the oblique direction: the
angle α in FIG. 3) may be appropriately set according to the purpose, but is typically 5 to 45
degrees .
[0020]
Preferably, as shown in FIG. 4, a buffer space 15 is defined between the left channel speaker 11L
and the center channel speaker 11C, and between the center channel speaker 11C and the right
channel speaker 11R. There is. The buffer space 15 has, for example, two partitions 12 between
the left channel speaker 11L and the center channel speaker 11C and two partitions 12C
between the center channel speaker 11C and the right channel speaker 11R to provide a space
between them. Can be formed by By defining such a buffer space 15, it is possible to prevent an
adverse effect due to the interaction between the speakers, and to obtain a speaker system
having an even better sound quality. Any appropriate sound absorbing material may be disposed
in at least a part of the buffer space 15 as needed. More specifically, the sound absorbing
material may be filled in the entire buffer space 15, or the sound absorbing material may be
attached to the partition wall 12 on the buffer space 15 side. By arranging the sound absorbing
material, the interaction between the speakers can be better prevented.

Preferably, as shown in FIG. 3, the horizontal mount 10 further includes a wire housing 13. That
is, the lead wires on the side of the speakers (left channel speaker 11L, right channel speaker
11R and center channel speaker 11C) are all connected and accommodated in the horizontal
base 10. As a result, the unsightline that the wiring is exposed indoors is eliminated. The wire
housing portion 13 has, for example, a winding structure (more preferably, a reel structure) 14.
By adopting a take-up structure, the length of the end of the speaker lead wire exposed to the
outside of the speaker system can be adjusted, so the wiring exposed indoors (outside the
speaker system) should be minimized. Can. In addition, since wiring of the speaker (and each
device such as an amplifier if necessary) is completed in the wiring housing portion 13, the user
can connect the speaker terminal of the television to the television side end of the lead wire of
the speaker All you need to do is connect the parts. Therefore, a user-friendly speaker system for
a large television with the complexity of connection eliminated is obtained.
[0022]
The legs 20 have characteristics (e.g., strength and stability) which are sufficient to hold the
horizontal base 10 on which the large-sized television is placed horizontally. The structure of the
legs 20 is not particularly limited as long as the horizontal base 10 can be stably held
horizontally, but preferably, as shown in FIG. 1, the entire sides of the horizontal base 10 are
supported. Such a structure is excellent in retention stability. Furthermore, by making the interior
hollow, the legs 20 can also function as a volume space of the speaker system, or further
speakers and / or various devices can be incorporated (described later).
[0023]
Preferably, the legs 20 may be equipped with additional speakers. The type and configuration of
the speakers mounted on the legs 20 can be appropriately selected according to the purpose.
The speaker may be mounted on one of the legs 20 or both. When both are equipped, both may
be equipped with the same kind of speaker, and may be equipped with a different kind of
speaker. Typically, one of the legs 20 is equipped with a subwoofer. In that case, the other of the
legs 20 may be equipped with an amplifier. By adopting such a configuration, it is possible to
reproduce a more realistic sound field. In addition, the wiring of the equipment with which the
leg part 20 was equipped may also be accommodated in the wiring accommodating part 13 of

Although the preferred embodiments of the present invention have been described above, the
present invention is not limited to these embodiments. For example, a speaker may be installed
on the side and / or the back of the horizontal base 10. Also, for example, a damping material or
a sound absorbing material (for example, cork, foamed polyethylene) may be disposed between
the horizontal mount 10 and the leg 20. Also, for example, the leg portion 20 may be used as an
article storage unit without being equipped with any device. Although the partition wall is
provided obliquely in the above embodiment, the partition wall may be provided in parallel with
the axial direction of the speaker. Therefore, the buffer space may also be defined parallel to the
axial direction of the speaker.
