DESCRIPTION JP2002078053
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
acoustic system in a bathroom such as a system bus, and more particularly to a bathroom
acoustic system capable of obtaining high-quality sound from bass to treble.
[0002]
2. Description of the Related Art Conventionally, as an acoustic system of a bathroom such as a
system bus, there is disclosed, for example, in Japanese Utility Model Laid-Open Publication No.
6-58057 or Japanese Patent Laid-Open Publication No. 3-15423. The sound system of the
former (Japanese Utility Model Laid-Open No. 6-58057) has a speaker for a bathroom installed
on a ceiling or wall of a bathroom, and this speaker for a bathroom is configured to reproduce all
sounds from bass to treble. is there.
[0003]
The latter acoustic system (Japanese Patent Application Laid-Open No. 3-15423) forms an
acoustic unit by a voice coil, a magnet and a yoke fixed to a dish-like frame, and around the
frame of the acoustic unit is a bathtub wall surface. It is made to closely_contact | adhere to and
fix, and it is comprised so that a bathtub itself may be vibrated as a sounding body by an acoustic
unit, and a sound may be reproduced.

[0004]
However, in the former sound system, one relatively small speaker is simply attached to the
horizontal ceiling or vertical wall of the bathroom, and this speaker is used to make bass to treble
Because the sound is reproduced in the entire frequency band up to the point, the reproduction
of the bass in the bathroom is insufficient. For example, when appreciating music, it is difficult to
obtain a good acoustic distribution (acoustic characteristics) in the bathroom There was a
problem.
[0005]
In this point, the latter acoustic system is a system in which an acoustic unit is attached to the
wall of a bathtub and sound of a frequency band that can be viewed by human beings is
reproduced by this acoustic unit with a relatively large bathtub wall as a diaphragm. Although
the bass is relatively well reproduced, the acoustic unit is directly attached to the bathtub wall, so
the vibration of the bathtub wall tends to transmit mechanical vibration directly to the bather.
There was a problem that it may be accompanied by discomfort.
[0006]
The present invention has been made in view of the above circumstances, and the object of the
invention according to claim 1 is that the small-sized speaker and the large-sized speaker for
reproducing the low-pitched sound are placed in the bathroom at an optimum position. It is an
object of the present invention to provide a bathroom sound system capable of obtaining a good
sound distribution without noise and facilitating installation of a large speaker.
In addition to the object of the invention according to claim 1, the object of the invention
according to claim 2 is that the large speaker can be easily installed on the outer surface of the
wall panel corresponding to the optimum closed space in the bathroom, and the sound
distribution is better. The object of the invention according to claim 3 is, in addition to the object
of the invention according to claim 1 or 2, a bathroom in which bass is effectively reproduced to
obtain a better acoustic distribution. It is about providing an acoustic system.
[0007]
SUMMARY OF THE INVENTION In order to achieve the above object, the invention according to
claim 1 of the present invention is a small speaker installed on the ceiling panel or wall panel of a
bathroom, and a small speaker in the bathroom. A large-sized speaker for reproducing lowpitched sound installed on a bathroom outer wall corresponding to a closed space to be formed is

provided, and the closed space is in communication with the washing place through an opening.
[0008]
By this configuration, the sound such as music can be reproduced as the space in the bathroom
as the effective space (sound space) by the small speaker installed on the ceiling panel or the wall
panel of the bathroom.
On the other hand, the bass is reproduced as an effective space by a large speaker installed on
the outer wall of the bathroom corresponding to the closed space formed in the bathroom.
As a result, a large speaker whose directivity is not influenced by the place of occurrence can be
installed on the bathroom outer wall in a closed space, a small speaker can be installed at a
desired position of each panel, and there is no unpleasant feeling due to mechanical vibration or
the like in the bathroom. An acoustic distribution can be obtained, and a large speaker can be
easily installed on the bathroom outer wall of a closed space, which is a place that is not visible
from inside the bathroom and does not impair the design of the bathroom.
[0009]
The invention according to claim 2 is characterized in that the closed space is formed inside the
counter or the bathtub apron, and the opening is provided in the counter apron or the bathtub
apron.
With such a configuration, the large speaker can be installed on the outer wall of the bathroom
corresponding to the closed space which is inevitably formed in the bathroom, and the
installation can be further facilitated, and the large speaker is reproduced. Low-pitched sound is
transmitted to the washroom from the openings provided in each apron that separates each
closed space and the washroom, and a better acoustic distribution is obtained in the bathroom.

The invention according to claim 3 is characterized in that the opening and the large speaker are
in communication via a duct. By configuring in this manner, since the low-pitched sound
reproduced by the large-sized speaker is transmitted from the opening through the duct into the
washroom (bathroom), an effective low-pitched sound reproduction can be obtained in the
bathroom. Good acoustic distribution is obtained.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present
invention will be described in detail with reference to the drawings. 1 to 3 show an embodiment
in which a bathroom sound system according to the present invention is applied to a system bus,
and FIG. 1 is a schematic perspective view of the inside, FIG. 2 is a schematic plan view of the
inside, FIG. Is a cross-sectional view of the installation portion of the large speaker.
[0012]
In FIG. 1 and FIG. 2, the system bus 1 is formed in a box shape by a waterproof pan 2, four wall
panels 3a to 3d as bathroom outer walls, and a dome-shaped ceiling panel 4, for example. . On
the waterproof pan 2, the bathtub 5 is disposed on the side of the wall panel 3a, and a washing
place 6 is provided on the side of the wall panel 3c. It is arranged.
[0013]
Small-sized speakers 8a and 8b having predetermined diaphragms (not shown) are provided on
the upper left and right sides of the wall panel 3b on the side of the ceiling panel 4. The small
speakers 8a and 8b are made waterproof by using, for example, resin-made cone paper as a
diaphragm, and reproduce sound from low to high. The small speakers 8a and 8b have, for
example, an impedance of 8? and a reproduction frequency band of 100 to 15000 Hz.
[0014]
Further, the installation positions of the small speakers 8a and 8b are not limited to the upper
portion of the wall panel 3b, for example, they may be installed on the upper portions of the
opposing wall panels 3a and 3c as shown by the two-dot chain line a in FIG. It can also be
installed on the left and right sides on the wall panel 3b side of the ceiling panel 4 as indicated
02-05-2019
4
by the dot-and-dash line b, or on the left and right side wall portions 4a and 4b of the domeshaped ceiling panel 4 as indicated by the two-dot chain line c.
[0015]
A large speaker 9 is installed at a portion of the wall panel 3d facing the side wall (wall surface)
5a of the bathtub 5.
That is, as shown in FIG. 2, a closed space 11 is formed between the side wall 5 a of the bathtub
5 and each of the wall panels 3 a and 3 d and the bathtub apron 10. The speaker 9 is attached to
the wall panel 3d. As the large-sized speaker 9, for example, a super woofer or the like having an
impedance of 8? and a reproduction frequency band of 25 to 125 Hz is used, and like the small
speakers 8a and 8b, it is preferable to have a waterproof structure.
[0016]
For example, as shown in FIG. 3, the large-sized speaker 9 has its front frame 9a in contact with
the inner surface of the opening 12 formed in the wall panel 3d via the packing 22 and the
opening of the wall panel 3d. The reinforcing plate 13 is brought into contact with the outside of
the housing 12 as required, and the mounting screw 14 is screwed into a screw hole of the
reinforcing plate 13 from a mounting hole provided in the front frame 9a to attach to the wall
panel 3d. The mounting structure of the large-sized speaker 9 is an example, and it is possible to
directly fix the large-sized speaker 9 to the wall panel 3d with a wood screw, an adhesive or the
like without using the reinforcing plate 13, for example. In addition, the resonance (resonance)
phenomenon in the closed space 11 is actively utilized to facilitate bass sound in a specific
frequency range, or, for example, when the large-sized speaker 9 is relatively small, by the twodot chain line in FIG. As shown, the closed space 11 can be partitioned by the partition plate 15
so as to have a predetermined volume to make it easy to emit low-pitched sound.
[0017]
An opening 16 is provided in the bathtub apron 10 which divides the closed space 11 in which
the large speaker 9 is installed and the washing place 6. The opening 16 is formed by, for
example, an elongated hole with a width w in the vertical direction near the wall panel 3d of the
02-05-2019
5
bathtub apron 10 and protrudes in the closed space 11 by a predetermined size h (including h =
0). Due to the opening 16, the low-pitched sound reproduced by the large-sized speaker 9 as
described later is well transmitted to the washing place 6.
[0018]
As shown in FIG. 1, the large speaker 9 and the small speakers 8a and 8b are respectively
connected to the output terminals of an amplifier 17 disposed on the outer surface of the wall
panel 3c of the system bus 1, for example. The amplifier 17 is connected to an audio device such
as a CD player, a cassette deck, various tuners, etc. (not shown), and an operation panel 18
attached to the wall panel 3a, for example. By operating inside, the audio equipment is controlled
by wire or wirelessly.
[0019]
According to the system bus 1, for example, by operating a power switch or an operation button
(not shown) provided on the operation panel 18, music such as a CD player or cassette deck can
be displayed on the small speakers 8a and 8b and the large speakers 9. , And can be viewed
within the system bus 1. At this time, the sound of music is reproduced in stereo by the left and
right small speakers 8a and 8b disposed above the bather.
[0020]
Also, of the music sounds, the low-pitched sound is supplied to the large-sized speaker 9 and
reproduced, and this reproduced sound is directly transmitted to the washing place 6 from the
opening 16 provided in the bathtub apron 10 with the vibration sound in the closed space 11 It
is propagated. Sound waves transmitted directly from the opening 16 of the bathtub apron 10
reproduce a good bass with a sense of reality in the system bus 1, and for example, a bather in
the washroom 6 may hear the bass while feeling it with his body As well as being able to hear the
bass from the washroom 6 on the waterproof pan 2 located below the bather's head, for example,
even if the bather is in the bathtub 5, he can hear the bass with a sense of weight and presence it
can
[0021]
02-05-2019

As described above, in the system bus 1 of the above embodiment, the small speakers 8a and 8b
are provided at the upper part of the wall panel 3b, and the large speaker 9 for bass
reproduction is inevitably formed in the system bus 1. Because it is installed on the wall panel 3d
corresponding to the closed space 11 inside the bathtub apron 10 which is to be Sound (for
example, middle and high-pitched sound) can be reproduced, and the large-sized speaker 9 can
reproduce low-pitched sound.
[0022]
In particular, since the large speaker 9 is installed on the wall panel 3d which is the bathroom
outer wall corresponding to the closed space 11, the closed space 11 which was a conventional
simple space can be effectively used as an acoustic space, and Since 9 is installed below the
bather's head, when playing music, the small speakers 8a and 8b of the wall panel 3b reproduces
a heavy sound and a sense of presence that can not be reproduced. Ru.
[0023]
Further, even when the bather is in the washing place 6 or the bathtub 5, the large-sized speaker
9 installed on the outer surface side of the wall panel 3d corresponding to the closed space 11
inside the bathtub apron 10 closer to the bather Since it is possible to reproduce, even if the
generated sound level is small, it is possible to reproduce a low sound enough for hearing and
compared to the case where the large speaker 9 is provided at the top of the wall panel 3b 9)
Because the distance between the bather and the person can be set low and the sound pressure
level can be set low, the echo of the sound is suppressed and the localization does not become
unstable.
[0024]
Further, the large-sized speaker 9 capable of satisfactorily reproducing low-pitched sound such
as super woofer is used for low-pitched sound reproduction, and an opening 16 which can
propagate the sound in the closed space 11 directly to the bathtub 6 apron 10 side. Therefore,
the bass is efficiently propagated into the washing place 6 (system bus 1).
From these things, it is possible for the bather to have a sense of being aurally enveloped in the
music and to obtain a desirable acoustic distribution in the reproduction of the music in the
system bus 1.

[0025]
In addition, since the large speaker 9 is installed on the outer surface side of the wall panel 3d
corresponding to the closed space 11 inside the bathtub apron 10, the large speaker 9 is
previously installed at a predetermined position of the wall panel 3d, for example. Can be
assembled and installed by assembling the wall panel 3d, and the large-sized speaker 9 itself can
be easily installed on the system bus 1.
In addition, since the large speaker 9 itself is not visually recognized only from the opening 16
provided in the bathtub apron 10 from the inside of the system bus 1, the design of the system
bus 1 is not impaired by the installation of the large speaker 9.
[0026]
Furthermore, since the large speaker 9 having the diaphragm is installed on the wall panel 3d of
the system bus 1, the side wall 5a of the bathtub 5 is not directly vibrated mechanically, and the
conventional mechanical vibration is achieved. It is possible to reduce the direct propagation to
the bathers and to perform a comfortable bathing.
Further, since the small speakers 8a and 8b and the large speaker 9 have a waterproof structure
and the opening 16 is provided closer to the wall panel 3d, entry of water used in the washing
place 6 into the opening 16 is possible. For example, the water resistance of both speakers 8a,
8b, 9 can be improved so that a predetermined function can be exhibited with certainty, and
long-term stable use of the small speakers 8a, 8b or the large speaker 9 becomes possible.
[0027]
FIG. 4 shows a modification of the example of installation of the large-sized speaker 9, which is
characterized in that the opening 16 of the bathtub apron 10 and the large-sized speaker 9 are
connected by a duct 19. As shown in FIG. That is, one end 19 a of the tubular duct 19 bent in a
substantially L-shape is brought into contact with the back surface of the opening 16 of the
removable bathtub apron 10 via a vibration preventing member or the like (not shown) The
flange 19 c provided at the end 19 b is tightened together with the front frame 9 a of the large
speaker 9, the packing 22 and the reinforcing plate 13 with the mounting screw 14 on the wall
02-05-2019
8
panel 3 d. Thus, the duct 19 is disposed between the front surface of the large speaker 9 and the
opening 16.
[0028]
Also in this example, since the bass is reproduced by the large-sized speaker 9, the same function
and effect as the above embodiment can be obtained. In addition, the bass travels through the
duct 19 and enters the washroom 6 through the opening 16. Since the sound is propagated, by
setting the shape and length of the duct 19 appropriately, predetermined acoustic characteristics
can be obtained in the duct 19 so that bass reproduction becomes effective, and bass
reproduction in the system bus 1 is better. The effect and effect can be obtained. In addition,
since the low-pitched sound of the large-sized speaker 9 propagates in the duct 19, the vibration
of the side wall 5a of the bathtub 5 is further suppressed, so that the mechanical vibration is
more reliably prevented from being transmitted to the bather. .
[0029]
FIGS. 5 and 6 are cross-sectional views similar to FIGS. 3 and 4 showing another example of
installation of the large-sized speaker 9. The same parts as those in the above embodiment will
be described with the same reference numerals. The feature of this embodiment is that, as shown
by the two-dot chain line in FIGS. 1 and 2, the large speaker 9 is not provided in the wall panel 3
d corresponding to the closed space 11 formed inside the bathtub apron 10 but inside the
counter 7. It is in the point installed in the wall panel 3b corresponding to the closed space 20
formed.
[0030]
That is, in the system bus 1 in which the counter 7 is arranged, since the closed space 20 is
formed inside the counter 7, the wall panel 3b which is the outer wall of the system bus 1
corresponding to the closed space 20 is large. A speaker 9 is attached, and an opening 21 is
provided closer to the wall panel 3c of the counter apron 7a. Even with this configuration, the
large-sized speaker 9 can be installed on the wall panel 3 b with the closed space 20 inside the
counter 7 necessarily formed in the system bus 1 as the acoustic space (resonance box). The
same function and effect as in the case of installing the above in the closed space 11 can be
obtained.
02-05-2019
9
[0031]
Also in this embodiment, as shown in FIG. 6, the front face of the large-sized speaker 9 and the
opening 21 can be connected by a bent (or straight) duct 19. In this case, the duct 19 is provided
at its one end 19a with a flange 19c similar to the other end 19b, and this flange 19c may be
fixed, for example, to the inside of the opening 21 of the counter apron 7a. It may be fixed by
means of fixing means.
[0032]
In the above embodiment, the large speaker 9 can be installed on the outer surface of the wall
panel corresponding to one of the above-mentioned closed spaces 11 and 20 to obtain a desired
effect. , 20 can be installed on each of the outer surface of the wall panel. Further, the shape and
the number of the openings 16 and 21 in the above embodiment are not limited to one
longitudinally elongated hole, but may be formed by a circle or a laterally elongated elongated
hole, or a plurality of these may be provided. You can also use the gap between Furthermore, the
positions of the openings 16 and 21 can be changed as appropriate without departing from the
scope of the invention according to the present invention, such as providing the positions of the
openings 16 and 21 closer to the bathtub 5 and the counter 7.
[0033]
As described above in detail, according to the first aspect of the present invention, the small
speaker is installed on the ceiling panel or wall panel of the bathroom and the large speaker for
reproducing the low frequency sound is placed in the bathroom. Since it is installed in the
bathroom outer wall corresponding to the closed space which communicates with the washing
place through the opening, both speakers can be installed at the desired optimum position of the
bathroom, and discomfort due to mechanical vibration etc. in the bathroom As a result, it is
possible to facilitate the installation, for example, the large-sized speaker can be installed on the
bathroom outer wall of a closed space which is not visually recognized from inside the bathroom
and does not impair the design of the bathroom.
[0034]
According to the invention of claim 2, in addition to the effect of the invention of claim 1, a
closed space is formed inside the counter or inside the bathtub apron, and an opening is

provided in the counter apron or the bathtub apron. Therefore, the large-sized speaker can be
easily installed on the outer wall of the bathroom corresponding to the closed space inevitably
formed in the bathroom, and the installation can be further facilitated, and the low-pitched sound
reproduced by this large-sized speaker The sound is transmitted to the washroom from the
openings provided in the respective aprons that separate the closed space and the washroom,
and a better acoustic distribution can be obtained in the bathroom.
[0035]
According to the third aspect of the invention, in addition to the effects of the first or second
aspect of the invention, since the opening and the large-sized speaker are in communication with
each other through the duct, Sound is transmitted from the opening through the duct into the
washroom (bathroom), so that effective bass reproduction can be obtained in the bathroom and a
better acoustic distribution can be obtained.
