In the former sound reproducing device, a sound unit is formed by a voice coil, a magnet, and a yoke fixed to a dish-shaped frame, and the periphery of the frame of the sound unit is fixed in close contact with a bathtub wall surface, and the bathtub itself is fixed by the sound unit. The sound is reproduced by vibrating the sounding body.

In the latter sound reproducing apparatus, a speaker actuator is disposed on the ceiling of the bathroom or on the back of the wall of the bathroom, and the sound is reproduced by vibrating the structural material of the ceiling or the wall.

[0004]

However, in the former sound reproducing device, the sound unit is simply attached to the bathtub wall surface, and the sound in the frequency band that can be viewed by humans with this sound unit is used as one of the diaphragms. Because it is a system that reproduces on the large bathtub wall surface, although the low frequency is reproduced relatively well, the medium and high frequency sound is canceled out by the low frequency, for example, and it is difficult to reproduce clearly and the sound quality is poor, and However, since the acoustic unit is directly attached to the bathtub wall surface, mechanical vibration may be transmitted to the bather due to the vibration of the bathtub wall surface, and the bather tends to be uncomfortable.

In the latter sound reproducing apparatus, a speaker actuator is provided on the ceiling of the bathroom or on the wall of the bathroom, and these are vibrated as diaphragms.
As with the former sound reproducing device, it is difficult to clearly reproduce the sound in each frequency band (especially middle and high frequencies), and there is a problem that the sound quality is inferior.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object of the present invention is to reproduce sound in each frequency band favorably by reproducing low and medium high sounds separately. An object of the present invention is to provide a sound reproducing apparatus for a bathroom, which can obtain excellent sound quality and can prevent the influence of mechanical vibration on a bather and can comfortably take a bath. The object of the invention according to claim 2 is, in addition to the object of the invention according to claim 1, in which a space formed between a bathtub wall surface and a wall panel is effectively used as an acoustic space, thereby further improving bass sound quality. It is an object of the present invention to provide a bathroom sound reproducing device which can be obtained.

[0007]

In order to achieve the above object, according to the present invention, there is provided a waterproof speaker having a diaphragm attached to a ceiling panel or a wall panel of a bathroom, and a bathtub apron for a bathroom. , An actuator attached to a bathroom member other than the bathtub, such as a wall panel near the bathtub, a counter, and a ceiling panel, for reproducing mid-high sounds with a waterproof speaker, and reproducing bass sounds by vibrating the bathroom members with the actuator. It is characterized by the following.

[0008] With this configuration, the bass sound amplified by the amplifier is supplied to the actuator and is caused by vibration of a bathroom member other than the bathtub such as a bathtub apron or a wall panel near the bathtub having a relatively large area. The high and low sounds are reproduced by a waterproof speaker having a predetermined diaphragm. As a result, since the bass and the mid-high range are reproduced on separate diaphragms, a clear mid-high range is reproduced and a heavy bass is reproduced, so that a sound with excellent sound quality can be obtained in the bathroom. it can. Further, since the actuator is attached to a bathroom member other than the bathtub, direct mechanical vibration of the bathtub by the actuator is eliminated, and transmission of the vibration to the bather is prevented, and discomfort during bathing is prevented.

Further, the invention according to claim 2 is characterized in that the actuator is mounted on a wall panel surface corresponding to a wall surface other than the apron mounting side of the bathtub. With such a configuration, a space formed between the wall panel and the outside of the wall surface of the bathtub functions as an acoustic space, and bass reproduction with better sound quality can be obtained.

An apron 9 having a relatively large area and provided at a position very close to a bather who is taking a bath can play back low sounds and middle and high sounds with the speakers 8a and 8b using the apron 9 as a diaphragm. Since it is used as a diaphragm exclusively for bass, it is possible to reproduce heavy bass that cannot be reproduced by the waterproof speakers 8a and 8b on the ceiling when reproducing music.

Further, since the bass is reproduced by vibrating the apron 9 near the bather, even if the generated sound level is low, it is possible to reproduce bass which is sufficiently audible, and the distance is short and the sound is small. Since the pressure level is low, the reverberation of the sound is suppressed and the localization does not become unstable. Also,
Since the apron 9 having a relatively large area is used as a diaphragm for reproducing low-pitched sound, a sound spreading feeling can be obtained, and a sense of being wrapped in music can be obtained in a sense of hearing. It is possible to obtain excellent sound quality when playing music in the room.

Further, since the actuator 10 is attached to the apron 9, the mechanical vibration of the bathtub 5 is not directly generated by the actuator 10, and the generation of discomfort due to the transmission of the vibration to the bather can be suppressed. As a result, comfortable bathing can be performed.
