DESCRIPTION JPH05168080
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
listening room for enjoying music reproduced from speakers and a loudspeaker system used in
the listening room.
[0002]
2. Description of the Related Art In a conventional listening room, a plurality of speaker systems
are placed or mounted on the wall of the listening room in order to enjoy music such as surround
sound. Hereinafter, a conventional speaker system and a listening room are shown using
drawings.
[0003]
FIG. 3 shows a plan view of the listening room. In FIG. 3, 8 is an outer wall of the listening room,
9 is an inner wall of the listening room, 10 is an air layer provided between the outer wall 8 and
the inner wall 9 of the listening room, and 12 is a speaker system for reproducing sound waves.
is there.

The bookshelf speaker system 12 is attached to four places on the inner wall 9 of the listening
room, and is arranged to enjoy music such as surround sound.
[0005]
The outer wall 8 and the inner wall 9 are fixed by a frame (not shown), and an air layer 10 is
provided between the outer wall 8 and the inner wall 9 to enhance the sound insulation
performance.
[0006]
However, in the listening room configured as described above, the installation of the speaker
system requires a large amount of space, which restricts the installation of the AV apparatus or
furniture, or the AV apparatus There is a problem that the desired sound field can not be
obtained because the furniture or the like reflects the sound wave more than necessary.
[0007]
SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention
provides a listening room which is space-saving and capable of obtaining a desired sound field
without being affected by AV equipment and the like.
[0008]
[Means for Solving the Problems] In order to achieve this object, the listening room of the
present invention uses a speaker system in which an acoustic tube is disposed on the front of the
speaker unit, and a speaker cabinet is fitted to the listening room. It is composed of different
shapes and materials.
[0009]
With the above-described configuration, the listening room of the present invention can achieve
a desired sound field in a space-saving manner without the influence of AV equipment and the
like, and can realize a high-performance sound insulation performance.
[0010]
An embodiment of the present invention will be described below with reference to the drawings.

(FIG. 1) is a structural cross-sectional view and a perspective view of a speaker system according
to an embodiment of the present invention, (FIG. 1 (a)) is a cross-sectional view, (FIG. 1 (b)) is a
longitudinal cross-sectional view, 1 (c) is a perspective view.
Also, FIG. 2 shows a plan view of the listening room.
[0011]
In FIG. 1, 1 is a speaker unit, 2 is a speaker cabinet for confining sound waves radiated from the
back of the speaker unit 1, 3 is an acoustic tube for guiding sound waves disposed on the front of
the speaker unit 1, 4 is a speaker A sound conducting portion for guiding a sound wave radiated
from the front of the unit 1 to the opening of the acoustic tube 3, 5 is a partition plate disposed
in the acoustic tube 3, 6 is disposed between the partition plate 5 and the acoustic tube 3 7 is a
hole for fastening screws.
[0012]
In FIG. 2, 8 is an outer wall of the listening room, 9 is an inner wall of the listening room, 10 is an
air layer provided between the outer wall 8 and the inner wall 9 of the listening room, 11 is a
sound wave shown in FIG. It is a speaker system for reproducing.
[0013]
Sound waves radiated from the front surface of the speaker unit 1 have flat sound pressure
frequency characteristics obtained by the effects of the partition plate 5 and the sound absorbing
material 6 disposed inside the acoustic tube 3 (for example, JP-A-1-276997) (Japanese Patent
Application Laid-Open No. 1-279698).
[0014]
The speaker cabinet 2 of the speaker system 11 is made of the same material and shape as the
outer wall 8 of the listening room.
Furthermore, the opening of the acoustic tube 3 of the speaker system 11 is arranged to be
exposed at the corner of the listening room as shown in FIG.

In the present embodiment, the particle board (12 mm in thickness) is used as the outer wall 8
and the speaker cabinet 2. However, the material is not limited to the particle board and may be
composed of any material.
The outer wall 8 and the inner wall 9 are fixed by a frame (not shown), and an air layer 10 is
provided between the outer wall 8 and the inner wall 9 to enhance the sound insulation
performance.
Further, the speaker system 11 is configured to be attached to the frame through the fastening
holes 7 (not shown).
[0015]
The listening room configured as described above uses a speaker system in which an acoustic
tube is disposed on the front of the speaker unit, and the speaker cabinet is configured with a
shape and material adapted to the listening room. Therefore, the desired sound field can be
obtained with less space and without the influence of the AV equipment etc., and the sound
insulation performance with high performance can be realized.
