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 the sound reproducing apparatus according to the present invention is applied to a unit bathroom. FIG. 1 is a schematic perspective view of the inside, and FIG. FIG. 3 and FIG. 3 are longitudinal sectional views thereof.
[0014]
In FIG. 1, a unit bathroom 1 (referred to as a bathroom 1) has a box shape formed by a waterproof pan 2, four wall panels 3a to 3d (the wall panel 3d is not shown), and a dome-shaped ceiling panel 4, for example. Is formed. On the waterproof pan 2, a bathtub 5 is arranged on the wall panel 3a side, a washing place 6 is provided on the wall panel 3c side, and a counter 7 for placing a basin is provided on the wall panel 3b side of the washing place 6. Are located.
[0015]
Small speakers 8a and 8b having a predetermined diaphragm (not shown) are installed on the left and right sides on the ceiling panel 4 side of the wall panel 3b. The small speakers 8a and 8b have a waterproof structure by using, for example, a cone paper made of resin as a diaphragm, and reproduces sounds from medium to high. The small speakers 8a and 8b have, for example, an impedance of 8Ω and a reproduction frequency band of 100 to 25000 Hz, preferably 100 to 20,000 Hz.
[0016]
The installation positions of the small speakers 8a and 8b are not limited to the wall panel 3b, but may be installed on opposing wall panels 3a and 3c as shown by a two-dot chain line a in FIG. In this manner, the dome-shaped ceiling panel 4 can be installed on the left and right side walls 4a and 4b of the dome-shaped ceiling panel 4 as shown by a two-dot chain line c.
[0017]
A super woofer 9 is provided in the counter 7. As shown in FIGS. 2 and 3, the super woofer 9 is attached to a speaker box 10 having a predetermined volume and having a baffle plate 10a. It is fixed on the top with screws or adhesive. Thereby, the super woofer 9 is installed via the speaker box 10 in a substantially closed space 12 formed by the front wall 7a and the upper wall 7b of the counter 7 and the wall panels 3b and 3c. The super woofer 9 has, for example, an impedance of 8Ω and a reproduction frequency band of 25 to 125 Hz.
[0018]
An opening 13 is provided in the front wall 7 a of the counter 7 in correspondence with the speaker box 10. The opening 13 is formed as an elongated hole in the vertical direction near the front panel 7a, for example, near the wall panel 3c, so that the bass reproduced by the super woofer 9 propagates well into the washing place 6 as described later. Is done. In addition, the super woofer 9 is also made to have a waterproof structure by using, for example, resin cone paper, similarly to the small speakers 8a and 8b. As the waterproof structure, for example, the speaker box 10 itself has a waterproof structure. Alternatively, another appropriate waterproof structure such as covering the opening 13 with a one-way air-permeable waterproof sheet to make the super woofer 9 indirectly a waterproof structure can be adopted.
[0019]
The small speakers 8a and 8b and the super woofer 9 are connected to output terminals of an amplifier 14 arranged outside the bathroom 1 as shown in FIG. Audio equipment such as a CD player, a cassette deck, and various tuners (not shown) is connected to the amplifier 14, and an operation panel 15 attached to, for example, the wall panel 3 a is connected to the amplifier 14. By operating the inside, the audio equipment is controlled by wire or wirelessly.
[0020]
According to the bathroom 1, music of a CD player, a cassette deck, or the like is reproduced by the small speakers 8a and 8b and the super woofer 9 by operating, for example, a power switch and operation buttons (not shown) provided on the operation panel 15. Can be viewed in the bathroom 1. At this time, the middle and high pitch region of the music is clearly reproduced in stereo by the small left and right speakers 8a and 8b arranged above the bather.
[0021]
The bass region of the music is supplied to the super woofer 9 and reproduced, and the reproduced sound is such that the vibration sound in the space 12 is directly transmitted to the washing place 6 from the opening 13 provided in the front wall 7a. The sound wave directly transmitted from the opening 13 of the counter 7 reproduces a realistic low tone in the bathroom 1, for example, a bather in the washing room 6 hears the low tone while feeling it directly with the body. be able to.
[0022]
Further, since the opening 13 of the counter 7 is provided near the wall panel 3c, the sound wave directly propagated from the opening 13 is reflected by the wall panel 3c and propagates to the entire area in the bathroom 1. 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. I can do it [0023]
As described above, in the sound reproducing apparatus of the bathroom 1 of the above embodiment, the super woofer 9 for bass reproduction is installed in the space 12 inside the counter 7, and the small speakers 8a, 8b for mid / treble reproduction are mounted on the wall. Since it is installed above the panel 3b, bass sounds can be reproduced by the super woofer 9 and middle and high sounds can be reproduced by the small speakers 8a and 8b. In particular, since the super woofer 9 is installed in the substantially closed space 12, the space 12 can be used as an acoustic space, and the super woofer 9 is a washing place 6 (waterproof pan 2) below the bather's head. Since it is installed on the upper side, when playing music, bass sounds with a sense of weight and presence that cannot be reproduced by the small speakers 8a and 8b of the wall panel 3b are reproduced.
[0024]
In addition, even when the bather is in the washing room 6 or the bathtub 5, the bass can be reproduced by the super woofer 9 installed in the counter 7 closer to the bather, so that even if the generated sound level is low, the listening level is sufficient. The bass can be reproduced at a low level, and the distance between the bass reproduction section (super woofer 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. Nor.
[0025]
Furthermore, since the super woofer 9 capable of reproducing bass sound satisfactorily for bass reproduction is used, and the front wall 7a of the counter 7 is provided with the opening 13 through which the sound in the space 12 can be directly transmitted to the washing place 6 side. , Bass is efficiently transmitted to the washing place 6 (in the bathroom 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 (acoustic characteristics) in the reproduction of music in the bathroom 1.
[0026]
Further, since the super woofer 9 is installed in the space 12 in the counter 7 via the speaker box 10, mechanical vibration of the bathtub apron 16 and the like of the bathtub 5 is eliminated, and the vibration due to transmission of the vibration to the bather is eliminated. Pleasant sensation can be suppressed, and comfortable bathing can be performed.
[0027]
Furthermore, since the small speakers 8a and 8b and the super woofer 9 have a waterproof treatment structure, their water resistance is improved, and even if steam or water droplets adhere, a predetermined function can be surely exhibited. In addition, since the opening 13 provided in the front wall 7a of the counter 7 is formed near the wall panel 3c, it is possible to minimize intrusion into the space 12 such as splashes when washing the body in the washing place 6. In addition, the attachment of water droplets and the like to the super woofer 9 installed in the space 12 is prevented. Thus, the small speakers 8a and 8b and the super woofer 9 can be stably used for a long time.
[0028]
In the above example, the super woofer 9 is attached to the baffle plate 10a of the speaker box 10, and the speaker box 10 is fixed on the waterproof pan 2 via the fixture 11, for example, as shown in FIGS. 4 and 5. As described above, the super woofer 9 can also be attached to the wall panel 3b via the plate-shaped fixture 31 (or directly) without using the speaker box 10 but using the super woofer attachment hole 30 of the wall panel 3b. According to this structure, the mounting structure of the super woofer 9 can be simplified and the installation can be facilitated, for example, the above-mentioned speaker box 10 or the like is not required, and the related members for mounting the speaker can be saved.
[0029]
Further, in the above example, the case where the opening 13 is a long hole simply formed in the front wall 7a of the counter 7 has been described, but for example, the opening 13 may be configured as shown in FIG. 6 or FIG. You can also. That is, as shown in FIG. 6, a cylinder 21 is fixed to the rear side of the opening 13 of the counter 7, and the opening of the baffle plate 10 a of the speaker box 10 to which the super woofer 9 is attached is fixed by the cylinder 21. Is communicated with the opening 13. At this time, the cylindrical body 21 may be formed separately from the baffle plate 10a and the counter 7, or may be integrally formed therewith.
[0030]
With this configuration, the bass can be guided to the opening 13 by the cylinder 21 and the interior of the cylinder 21 can be used as an acoustic space, so that a better bass can be obtained. Also in this case, as shown in FIG. 7, the super woofer 9 is directly attached to the super woofer mounting hole 30 of the wall panel 3b via the fixture 31, and the front surface of the super woofer 9 and the opening 13 of the counter 7 are connected. The communication can also be performed by the cylindrical body 21.
[0031]
As shown in FIG. 8, the opening 13 itself may be formed by a cylindrical body 17, and the tip 17 a may be protruded into the space 12 by a predetermined dimension. With such a configuration, for example, the state of the bass transmitted to the washing area 6 can be adjusted according to the size of the bathroom 1 and the like, depending on the position of the distal end portion 17a of the cylindrical body 17, and more effective bass is reproduced. In addition to this, intrusion of water or the like into the space 12 through the opening 13 is further suppressed. Also in this case, as shown in FIG. 9, the super woofer 9 can be directly mounted on the super woofer mounting hole 30 of the wall panel 3b via the fixture 31.
