DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a loudspeaker
system for creating a sound field with one ideal sound 411 characteristic. Conventionally, when
reproducing an audio signal with high fidelity, as shown in FIG. 2, for example, as shown in FIG.
2, for example, using the speaker system 3 in which the speaker unit 2 is mounted on the #
surface of the enclosure as shown in FIG. It arranges in room 4 with an appropriate interval. しか
しながらこの、qo。 When playing an audio signal with a configuration like button X, the
sound reproduced from the speaker system 3 receives the shadow of the room 4, that is, the
sound exchange characteristic of the sound field, it is extremely important to obtain an ideal
characteristic. It was in need. In addition, due to the size and structure of the room, the sound
characteristics of the room have a problem that it requires a lot of effort in terms of cost and
time to improve it in order to significantly change. In addition, there is also a disadvantage that it
is necessary to use a headphone or to reduce the size of 9r-M, because the reproduction of the
audio signal with the loud sound cover may cause a great deal of trouble to the surroundings.
The present invention has been made under the above circumstances, and it is an object of the
present invention to provide a speaker system capable of reproducing an audio signal at a
desired volume with an ideal sound 41 characteristic. An embodiment of the present invention
will be described in detail with reference to a plan view shown in FIG. 3 and a side sectional view
shown in FIG. In the figure, 11 is a cuboid capsule whose wall is made of a soundproof material.
The capsule size is sized to allow the listener 12 to hear the signal entering and reproduced.

Reference numeral 13 denotes a partition plate provided to define the inside of the capsule 11
into two sections. Then, a through hole is formed at a predetermined position of the partition
plate 13, and the speaker unit 14 is referred to here, and a sound wave is emitted to one section
defined by the partition plate 13, that is, the sound field 15. ing. A door 16 for the listener 12 to
enter and leave the section of the sound field 15 @ is provided. In the sound field 15 of the
Gussel 11, the inner wall is treated with the acoustic treatment material 17 to provide the
acoustic installation so as to obtain the best acoustical properties. The other section 18 is also
filled with a sound absorbing material 19 or the like according to the installation conditions.
Further, each speaker unit 14 is extracted to the connection terminal 20 of the outer wall of the
capsule 11 so as to connect the raw output of the audio number given from the anng position not
shown here. In such a configuration, the listener first opens the door 16 to enter the sound field
15, and supplies an audio signal from an amplifier or the like to the speaker unit 14 via the
connection terminal 20 or 1 terminal.
Then, the sound wave reproduced by the speaker unit 14 is emitted to the sound field 15, and
the listener 12 can listen to the sound. Therefore, the size of the capsule 11 is smaller than that
of a general residential house, and the area of the inner wall is also the best sound quality due to
the fact that it has a J-score and a shell-like tightness. Characteristics can be easily obtained. Also,
by using a soundproof material on the wall side with a good degree of sealing, a good sound
insulation property can be obtained, and there is no concern that the surroundings will be
disturbed even if it is reproduced with daiji rice in the sound field 15. In addition, this invention
is not limited to the said Example, For example, force! A caster or the like may be provided on the
lower surface of the serno 1 so that it can be moved easily. It may be possible to directly perform
the operation of the Anzo strip which reproduces and amplifies the No. s-W's sound. As described
in detail above, according to the present invention, the inside of the capsule is defined by a tIJ
plate, and the speaker unit is attached to this partition plate and disposed in a section of one
force. Sound waves are emitted to the picture to form a sound field here. Therefore, it is possible
to provide a speaker system capable of easily obtaining an ideal sound 41s sound field and
reproducing an audio signal at a desired volume. lkム
