DETAILED DESCRIPTION OF THE INVENTION

[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 bath, and more particularly to a bathroom acoustic system capable of obtaining high sound quality from low to high.

[0002]

2. Description of the Related Art Conventionally, an acoustic system for a bathroom such as a system bath is disclosed in Japanese Utility Model Application Laid-Open No. 6-58057 or Japanese Patent Application Laid-Open No. 3-15423. The former (Japanese Utility Model Laid-Open No. 6-58057) sound system
A bathroom speaker is installed on a ceiling or a wall of a bathroom, and the bathroom speaker reproduces all sounds from low to high.

In the latter acoustic system (JP-A-3-15423), an acoustic unit is formed by a voice coil, a magnet, and a yoke fixed to a dish-shaped frame, and the periphery of the acoustic unit frame is surrounded by a bathtub wall. The sound unit reproduces sound by vibrating the bathtub itself as a sounding body with the sound unit.

[0004]

However, in the former acoustic system, one relatively small loudspeaker is simply mounted on a horizontal ceiling or a vertical wall of a bathroom. Due to the structure that reproduces sound in the frequency band, bass reproduction in the bathroom is insufficient. For example, when listening to music, it is difficult to obtain a good acoustic distribution (acoustic characteristics) in the bathroom. there were.

[0005] In this respect, the latter acoustic system mounts an acoustic unit on a bathtub wall surface and reproduces sound in a frequency band that can be viewed by a human with this acoustic unit on one relatively large bathtub wall surface as a diaphragm. Because
The bass is reproduced relatively well, but the acoustic unit is directly attached to the bathtub wall, so the vibration of the bathtub wall makes it easy for mechanical vibrations to be directly transmitted to the bather, making the bather uncomfortable. There was a problem that it might be accompanied.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object of the present invention is to provide an uncomfortable feeling in a bathroom by installing a small speaker and a large speaker for reproducing low-pitched sound at optimal positions. It is an object of the present invention to provide a bathroom sound system which can obtain a good sound distribution without noise and can easily install a large speaker. In addition, the object of the invention described in claim 2 is, in addition to the object of the invention described in claim 1, in that a large speaker can be easily installed on an outer surface of a wall panel corresponding to an optimum closed space in a bathroom, and a better sound distribution can be obtained. A third aspect of the present invention is to provide a bathroom sound system which can obtain a sound distribution which can effectively reproduce bass sound and obtain a better sound distribution in addition to the objects of the first or second invention. It is to provide an acoustic system.

[0007]

In order to achieve the above object, according to the first aspect of the present invention, there is provided a small speaker installed on a ceiling panel or a wall panel of a bathroom and a small speaker formed in the bathroom. A large speaker for bass reproduction installed on the outer wall of the bathroom corresponding to the closed space, wherein the closed space is communicated with a washing place via an opening.

[0008] With such a configuration, sound such as music is reproduced by a small speaker installed above the ceiling panel or wall panel of the bathroom, using the space in the bathroom as an effective space (acoustic space). On the other hand, the bass is reproduced by a large speaker installed on the outer wall of the bathroom corresponding to the closed space formed in the bathroom, using the closed space as an effective space. This makes it possible to install a large speaker whose directivity does not depend on the place of occurrence on the outer wall of the bathroom in a closed space, and to install a small speaker at a desired position on each panel, so that there is no discomfort due to mechanical vibration or the like in the bathroom. The acoustic distribution can be obtained, and the large speaker can be easily installed on the outer wall of the bathroom in a closed space, which is a place that is not visually recognized from the bathroom and does not impair the design of the bathroom.

The invention according to claim 2 is characterized in that the closed space is formed inside the counter or inside the bathtub apron, and the opening is provided in the counter apron or bathtub apron. With this configuration, the large speaker can be 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 large speaker can be reproduced by the large speaker. Bass sound is transmitted to the washing place from the openings provided in each apron that separates each closed space and the washing place, and a better sound distribution is obtained in the bathroom.

Further, the invention according to claim 3 is characterized in that the opening and the large speaker are communicated via a duct.

A large speaker 9 is provided on 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. A speaker 9 is mounted on the wall panel 3d. As the large loudspeaker 9, for example, a super woofer having an impedance of 8Ω and a reproduction frequency band of 25 to 125 Hz is used, and preferably has a waterproof structure like the small loudspeakers 8a and 8b.

As shown in FIG. 3, for example, 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. 12 is attached to the wall panel 3d by abutting a reinforcing plate 13 on the outside as necessary, and screwing a mounting screw 14 into a screw hole of the reinforcing plate 13 from a mounting hole provided in the front frame 9a.
Note that the mounting structure of the large speaker 9 is an example,
For example, it is also possible to directly fix to the wall panel 3d with a wood screw or an adhesive without using the reinforcing plate 13. In addition, if the resonance (resonance) phenomenon in the closed space 11 is positively used to easily produce a low frequency sound in a specific frequency range, or when the large speaker 9 is relatively small, for example, the two-dot chain line in FIG. As shown in the figure, the closed space 11 can be partitioned by a partition plate 15 so as to have a predetermined capacity, so that bass can be easily generated.

Further, the bathtub apron 10 for partitioning the closed space 11 in which the large-sized speaker 9 is installed and the washing place 6 is provided.
Is provided with an opening 16. This opening 16
Is formed as a vertically long hole having a width w near, for example, the wall panel 3d of the bathtub apron 10 and a closed space 11
A predetermined dimension h (including h = 0) protrudes into the inside. Through this opening 16, low-frequency sounds reproduced by the large loudspeaker 9, as described later, are favorably transmitted into the washing place 6.

The large speaker 9 and the small speaker 8
As shown in FIG. 1, a and 8b are respectively connected to output terminals of an amplifier 17 arranged on the outer surface of the wall panel 3c of the system bus 1, for example. The amplifier 17 is connected to audio equipment such as a CD player, a cassette deck, and various tuners (not shown), and an operation panel 18 attached to, for example, the wall panel 3a.
By operating the device 8 in the system bus 1, the audio device is controlled by wire or wirelessly.

According to the system bus 1, for example, by operating a power switch and operation buttons (not shown) provided on the operation panel 18, music from a CD player or a cassette deck can be transmitted to the small speakers 8a and 8b and the large speakers 9a. And can be viewed in the system bus 1. At this time, the music sound is stereo-reproduced by the small left and right speakers 8a and 8b arranged above the bather.

The bass sound of the music sound is supplied to the large speaker 9 and reproduced, and the reproduced sound is reproduced in the closed space 11.
Vibration sound inside the opening 16 provided in the bathtub apron 10
From the washing place 6. The sound wave directly transmitted from the opening 16 of the bathtub apron 10 reproduces a realistic and good bass sound in the system bath 1. For example, a bather in the washroom 6 can hear this bass sound while feeling it with his body. At the same time, the bass can be heard from the washing place 6 on the waterproof pan 2 located below the bather's head. For example, even when the bather is in the bathtub 5, the bass can be heard with a sense of weight and presence. it can

As described above, the system bus 1 of the above embodiment is
In the above, small speakers 8a and 8b are installed above the wall panel 3b, and large speakers 9 for low-frequency sound reproduction are provided on the wall corresponding to the closed space 11 inside the bathtub apron 10 which is inevitably formed in the system bus 1. Since the speakers 8a, 8b, and 9 are installed at the optimum positions in the system bus 1 because they are installed on the panel 3d, predetermined sounds (for example, middle and high sounds) can be reproduced by the small speakers 8a and 8b. The bass can be reproduced by the large speaker 9.

In particular, since the large speaker 9 is installed on the wall panel 3d, which is the outer wall of the bathroom corresponding to the closed space 11, the closed space 11 which has been merely a conventional space can be effectively utilized as an acoustic space, and the large speaker 9 can be effectively used. Since 9 is located below the head of the bather, when playing music, the bass speakers 3a and 8b of the wall panel 3b reproduce heavy and realistic bass sounds that cannot be reproduced by the small speakers 8a and 8b. You.

Further, even when the bather is in the washing room 6 or the bathtub 5, bass sound is produced by the large speaker 9 installed on the outer surface side of the wall panel 3 d corresponding to the closed space 11 inside the bathtub apron 10 located closer to the bather. Since the sound can be reproduced, even if the generated sound level is low, it is possible to reproduce a bass sound that is sufficiently audible, and the large speaker 9 is mounted on the wall panel 3.
b. Compared with the case of being provided above, the distance between the bass reproduction unit (large speaker 9) and the bather can be set short and the sound pressure level can be set low, so that the echo of the sound is suppressed and the localization becomes unstable. Not even.

Further, a large loudspeaker 9 capable of reproducing low-frequency sounds of a super woofer or the like is preferably used for reproducing low-frequency sounds, and an opening 16 through which the sound in the closed space 11 can be directly transmitted to the washing place 6 through the bathtub apron 10. Is provided, bass sound is efficiently propagated into the washing place 6 (system bus 1). From these facts, it is possible for the bather to have a sense of being enveloped in the music in the sense of hearing, and it is possible to obtain a desirable acoustic distribution in the reproduction of music in the system bus 1.

Further, since the large speakers 9 are installed on the outer surface side of the wall panel 3d corresponding to the closed space 11 inside the bathtub apron 10, the large speakers 9 are previously placed at predetermined positions on the wall panel 3d (construction site or factory). By mounting the wall panel 3d, the system bus 1 can be assembled and installed, and the large speaker 9 itself can be easily installed on the system bus 1. Further, since only the opening 16 provided in the bathtub apron 10 is visible from inside the system bus 1 and the large speaker 9 itself is not visible, the design of the system bus 1 is not impaired by the installation of the large speaker 9.

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 mechanically vibrated, and direct propagation of mechanical vibration to a bather as in the related art can be suppressed, so that comfortable bathing can be performed. In addition, since the small speakers 8a and 8b and the large speaker 9 have a waterproof structure and the opening 16 is provided near the wall panel 3d, the water used in the washing room 6 can enter the opening 16. For example, the water resistance of both speakers 8a, 8b, and 9 is improved, so that the predetermined functions can be reliably exhibited, and the small speakers 8a, 8b and the large speaker 9 can be used stably for a long period of time.

FIG. 4 shows a modification of the installation example of the large loudspeaker 9, which is characterized in that the opening 16 of the bathtub apron 10 and the large loudspeaker 9 are connected by a duct 19. That is, one end 19a of the cylindrical duct 19 bent in a substantially L shape is connected to the detachable bathtub apron 10.
Abutment is made on the back surface of the opening 16 through a vibration preventing member (not shown) or the like, and a flange 19 provided on the other end 19 b of the duct 19.
c, the front frame 9a of the large speaker 9, the packing 2
2. Together with the reinforcing plate 13, they are fastened together with the mounting screws 14 to the wall panel 3d. Thereby, the duct 19 is disposed between the front surface of the large speaker 9 and the opening 16.

Also in this example, since the bass is reproduced by the large speaker 9, the same operation and effect as in the above embodiment can be obtained.
Since the light is propagated from the washing machine 6 to the washing place 6, by setting the shape and length of the duct 19 appropriately, a predetermined acoustic characteristic can be obtained in the duct 19, and bass reproduction can be effectively performed. The effect that the reproduction | regeneration of a bass becomes more favorable is acquired. In addition, since the bass of the large speaker 9 propagates in the duct 19, the vibration of the side wall 5a of the bathtub 5 is further suppressed, and the effect of mechanical vibration to be more reliably prevented from being transmitted to the bather can be obtained. .

FIGS. 5 and 6 are sectional views similar to FIGS. 3 and 4, showing another example of installation of the large-sized speaker 9. FIG. In addition,
The same parts as those in the above embodiment are denoted by the same reference numerals and described.
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 placed on the wall panel 3 d corresponding to the closed space 11 formed inside the bathtub apron 10 but on the inside of the counter 7. The point is that it is installed on the wall panel 3b corresponding to the closed space 20 to be formed.

That is, in the system bus 1 in which the counter 7 is disposed, a closed space 20 is provided inside the counter 7.
Is formed, a large speaker 9 is attached to a wall panel 3b which is an outer wall of the system bus 1 corresponding to the closed space 20.
And an opening 21 is provided near the wall panel 3c of the counter apron 7a. Even with such a configuration, the large speaker 9 can be installed on the wall panel 3b using the closed space 20 inside the counter 7 necessarily formed in the system bus 1 as an acoustic space (resonance box). Can be obtained in the same manner as in the case where is installed in the closed space 11.

Also in this embodiment, as shown in FIG. 6, the front face of the large speaker 9 and the opening 21 can be connected by a bent (or straight) duct 19. In this case, the duct 19 has one end 19a and the other end 1a.
A flange 19c similar to 9b may be provided, and the flange 19c may be fixed to the inside of the opening 21 of the counter apron 7a, which is fixedly arranged, by a fixing means such as a screw or an adhesive.

In the above embodiment, the desired effect can be obtained by installing the large speaker 9 on the outer surface of the wall panel corresponding to one of the closed spaces 11 and 20 described above. , 20 can be installed on each of the outer surfaces of the wall panels. Further, the shape and number of the openings 16 and 21 in the above embodiment are not limited to one vertically long hole, but may be formed as a circular or horizontally long hole, or a plurality of these may be provided.
