plurality of speakers, at least one of which is incorporated inside the pedestal. The pedestal is
formed with a duct of a specific form, and the speaker incorporated inside the pedestal described
above is directed to the duct. The duct in which the speaker is directed as such is called a front
duct. FIG. 1 is a schematic view of a gantry of the present invention. FIG. 1 (A) is a front view, and
its X-X 'cross-sectional view is FIG. 1 (B). In the drawings, those with arrows in the leader lines
for reference numerals indicate spaces, and leaders without arrows indicate that some members
are present.
[0010]
The gantry 1 has a pedestal configured to allow an article to be placed thereon. The pedestal may
be supported by casters 31 as in the embodiment of FIG. The pedestal is generally in the form of
a rectangular parallelepiped, but is not particularly limited. At the top of the pedestal, there is
usually a top plate 27, and an article such as a television is placed on the top plate. Four speakers
are incorporated in the gantry 1 shown in FIG. Among them, three speakers 21, 22, 23 are
incorporated in the front of the pedestal so as to be directed to the outside of the gantry 1. The
other speaker 26 is disposed inside the pedestal without being exposed to the outside of the
gantry 1. The speaker 26 is directed to the duct 100 located vertically below. In the present
specification, “to direct the speaker” refers to arranging the speaker so as to direct the sound
and sound output from the speaker to a specific direction.
[0011]
The pedestal is provided with a plurality of vertical support plates. If the support plate is
structured to support the weight of an article such as a television mounted on a mount, it need
not extend in the entire vertical direction of the pedestal. For example, in the embodiment of FIG.
1, support plates 11, 12, 13, 14 are provided, which are present only in the lower region 10 of
the pedestal. The support plates 13 and 14 double as side surfaces of the gantry 1. A region
sandwiched between the support plate 11 and the support plate 12 constitutes a duct 100
opened toward the front of the gantry. Here, the duct refers to a space portion communicating
from the inside of the pedestal to the outside of the pedestal. The above area also serves as the
front duct 100 of the speaker 26. In other words, the speaker 26 is provided at about a half
position in the depth direction from the front surface of the gantry 1, and the sound pressure
emitted from the speaker 26 resonates in the inside of the duct 100 and is enhanced to emit
from the front opening. Be

[0012]
The speakers installed inside the pedestal preferably point outside the exterior of the cradle. In
the embodiment of FIG. 1, the speakers 26 do not face the outside of the gantry 1 but face the
front duct 100. By doing this, resonance in the inner space of the front duct 100 is likely to
occur, and sound enhancement becomes more effective. Preferably, as shown in FIG. 1B, a rear
bass reflex duct 103 is provided on the rear surface side of the gantry 1.
[0013]
The internal space (duct 100) in which the speaker 26 is directed is partitioned by the support
plates 11 and 12 separating the internal space of the pedestal. The support plates 11 and 12
simultaneously support the vertical support of the pedestal. With such a configuration, the
structural strength of the gantry 1 can be improved, and at the same time, the sound from the
speakers 26 incorporated in the gantry 1 can be enhanced.
[0014]
The speakers do not have to be arranged in all the spaces defined by the plurality of support
plates. For example, in the mode of FIG. 1, the space between the support plate 13 and the
support plate 11 is the storage portion 101, and the speaker is not incorporated. The storage
unit may be further partitioned by the shelf board 15 or the like.
[0015]
The speaker installed inside the pedestal is preferably a subwoofer. The subwoofer is a speaker
mainly responsible for the low frequency range where the main speaker can not reproduce
enough. The subwoofer is preferably responsible for the reproduction of sounds between 20 Hz
and 200 Hz, in particular between 20 Hz and 150 Hz. With regard to the bass, by resonating in
the above-mentioned internal space, it is expected to emit a more powerful bass.

Preferably, the gantry 1 is divided into an upper area 20 and a lower area 10. The upper area is
an area mainly for incorporating the speaker, which is one side (usually the front side). ) Is
composed of a panel incorporating multiple speakers. Preferably, the loudspeakers integrated in
the panel face the exterior of the cradle 1. In the embodiment of FIG. 1 (A), the front of the upper
area 20 is composed of a panel 24 incorporating three speakers 21, 22, 23.
[0017]
The lower area 10 is an area mainly used as a storage space. In the lower region 10, the abovedescribed support plate is provided in the vertical direction. The duct formed by the inner space
partitioned by the support plate is also preferably in the lower region. In the aspect of FIG. 1, the
opening of the front duct 100 is provided in front of the lower region, and the opening of the
storage portion 101 is also provided.
[0018]
Preferably, the speaker integrated inside the pedestal is integrated inside the upper region of the
pedestal. Also preferably, the speaker incorporated in the inside of the pedestal is directed
vertically downward. In the embodiment of FIG. 1, the speaker 26 incorporated in the inner space
is in the upper region 20 and is directed downward. As a result, sound and sound can be
resonated by effectively utilizing the volume of the lower region 10 in a wide space, and a
powerful sound output can be created.
[0019]
According to another embodiment of the invention, the opening of the bass reflex duct may be in
front of the pedestal. FIG. 2 is a schematic cross-sectional view of a gantry according to another
embodiment of the present invention. The left side of the drawing is the front direction of the
gantry. In this embodiment, there is a bass reflex duct 103 continuing from the back side of the
speaker 26 (preferably a subwoofer) incorporated inside the upper area 20 of the base, through
the lower area 10 to the opening of the front of the base. Also in this embodiment, the speaker
26 inside the pedestal is directed to the duct 100 constituted by the space portion partitioned by
the support plate (not shown).
