A waterproof power switch 11, a signal selection switch 12, a volume adjustment switch 13, a display unit 14, a charging terminal 15 and a charging terminal 16 are provided on the upper lid 2a, respectively. In addition, the signal conversion unit 4 is provided in the lower container 2b. It is fitted by a waterproof structure fitting portion formed at each end of the upper lid 2a and the lower container 2b, and is integrally connected by fixing the four corners with screws 30, 30,. 2 is configured as a waterproof sealed housing as a whole. Further, the waterproof container 2 incorporates the signal generation unit 3, the power supply unit 5, the control unit 6, the audio signal input terminal 21, and the recording switch 17 shown in FIG. Further, the container 2 has a structure in which the specific gravity is smaller than 1 as a whole and has buoyancy with respect to water by having a space inside, and the weight on the lower surface side of the waterproof container 2 is larger than the weight on the upper surface side Thus, the waterproof container 2 is configured to have a structure that floats stably in water with the lower surface of the waterproof container 2 facing down.

  Each of the pair of charging terminals 15 and 16 includes a waterproof cover with a resin lid.

  In FIG. 2, the block circuit diagram of the bathing apparatus 1 to which this invention is applied is shown.

  The bathing apparatus 1 includes a signal generation unit 3, a signal conversion unit 4, a power supply unit 5, a control unit 6, a power switch 11, a signal selection switch 12, a volume adjustment switch 13, a display unit 14, a charging terminal 15, a charging terminal 16, and a recording. A switch 17 is provided. The control unit 6 is connected to the signal selection switch 12, the volume adjustment switch 13, and the recording switch 22 and inputs an operation signal. In addition, the control unit 6 is connected to the display unit 14 and controls display on the display unit 14. Further, the control unit 6 is connected to the signal generation unit 3 and controls the operation of the signal generation unit 3.

  As an example, the signal generation unit 3 includes an A / D (analog / digital) converter, a D / A (digital / analog) converter, and a nonvolatile memory (all not shown). Under the control of the control unit 6, an electrical analog signal (sound wave signal) in the sound frequency band input from the audio signal input terminal is converted into a digital signal, stored in a nonvolatile memory, and the digital signal is reproduced as an analog signal. Then, a sound wave signal is generated and output to the signal conversion unit 4. In this case, the signal generation unit 3 is configured to record and reproduce a plurality of sound wave signals (three types of signals as an example).

  It should be noted that the signal generator 3 is provided with a sound wave signal that exerts a fatigue recovery effect at the time of factory shipment of the bathing apparatus 1, for example, a harmony signal described in Patent Document 1, a combination that has an effect on fatigue recovery, and a mental stability effect. Among the sound wave signals to be played, for example, Mozart music, and the sound wave signals having a beauty effect, for example, the harmony signal described in Patent Document 1, three types of sound wave signals having a beauty effect are recorded in advance.

  The signal converter 4 is a waterproof underwater speaker as an example, and converts an electrical signal into mechanical vibration. That is, an electric sound wave signal output from the signal generation unit 3 is converted into a mechanical vibration to generate a sound wave vibration.

  The power supply unit 5 includes a rechargeable battery 31, a diode 32, and a constant voltage circuit 33. The rechargeable battery 31 is configured by a chargeable / dischargeable battery such as a nickel cadmium rechargeable battery, a nickel metal hydride rechargeable battery, or a lithium ion rechargeable battery, and is charged between a positive electrode terminal (+ terminal) and a negative electrode terminal (−terminal). In addition to being charged by supplying electric power, the electric power for operating the entire bathing apparatus 1 is output. The rechargeable battery 31 has a positive terminal (+ terminal) connected to the positive charging terminal 15 via a backflow preventing diode 32 and is connected to the input side of the constant voltage circuit 33 via the power switch 11. It is connected. The rechargeable battery 31 has a negative electrode terminal (− terminal) connected to the negative electrode charging terminal 16 and a reference potential wiring (ground) of the bathing apparatus 1.

  The constant voltage circuit 33 stabilizes the DC voltage output from the rechargeable battery 31 to a predetermined voltage and outputs it to the signal generator 3, the controller 6, and the display unit 14.

  This bathing apparatus 1 is used as follows.

  First, charging of the rechargeable battery 31 of the bathing apparatus 1 will be described. The charger 101 shown in FIG. 3 is configured to be able to charge the rechargeable battery 31 and includes a charging completion lamp 105 that is turned on when charging is completed.

  First, the power switch 11 of the bathing apparatus 1 is turned off, and the lids of the waterproof covers of the charging terminals 15 and 16 are opened. Next, as shown in FIG. 3, the connection cable 10 audio signal input terminal 03 of the charger 101 is connected to the charging terminals 15 and 16, respectively, and the power cable 104 of the charger 101 is connected to a commercial AC power source. Thereby, charging power is supplied between the positive terminal and the negative terminal of the rechargeable battery 31 from the charger 101 via the charging terminals 15 and 16 and the diode 32, and charging of the rechargeable battery 31 is started. After a predetermined time has elapsed, the rechargeable battery 31 is fully charged and the charge completion lamp 105 is lit. Since charging of the rechargeable battery 31 is completed as described above, the charger 101 is removed from the bathing apparatus 1. Further, the lid of the waterproof cover of the charging terminals 15 and 16 is closed.

  As described above, the charger 101 connected to the commercial AC power source is connected to the charging terminal 15, without performing the complicated work of removing the screws 30, 30... And opening the waterproof container 2 for battery replacement and charging. The battery can be charged by a simple operation by simply connecting to the battery 16, and can be used repeatedly even when the remaining battery level is low.

  Next, the use in the bathtub 8 of the bathing apparatus 1 is demonstrated.

  As shown in FIG. 4, the bath 1 is floated on the bath water 10 in the bathtub 8 with the signal conversion unit 4 facing downward. Next, the power switch 11 is turned on. Thereby, the operation power stabilized by the constant voltage circuit 33 is supplied to each part. Next, the control unit 6 causes the signal generation unit 3 to reproduce a sound wave signal having a fatigue recovery effect as an initial value when the power is turned on, and causes the display unit 14 to display a display indicating fatigue recovery. Next, the signal generation unit 3 outputs a sound wave signal having a fatigue recovery effect to the signal conversion unit 4. Subsequently, the signal converter 4 vibrates the bath water 10 in contact with the signal converter 4 by converting the sound wave signal into sound wave vibration. Thereby, the sonic vibration propagates through the bath water 10 and reaches the bather 9, and the bather 9 is vibrated by the sonic vibration, and the flow of blood flow is promoted to provide a fatigue recovery effect. It is possible to adjust the sound wave vibration level by controlling the control unit 6 to change the output level of the signal generation unit 3 by operating the volume adjustment switch 13.

  Further, by operating the signal selection switch 12, it is possible to select and output a sound wave vibration that exhibits a fatigue recovery effect, a mental stability effect, and a cosmetic effect. In this case, the control unit 6 causes the signal generation unit 3 to output a sound wave signal previously associated with the selection of the signal selection switch 12 and causes the display unit 14 to display a display corresponding to the selection of the signal selection switch 12. When the mental stability effect is selected, a sound wave vibration having frequency fluctuation and intensity fluctuation is output, and the mental stability effect is produced. In addition, when a beauty effect is selected, high-frequency sound wave vibrations are output to easily remove dirt on the skin and achieve a beauty effect.

  Thus, the bathing apparatus 1 does not require the wiring of the cable, and can be used simply by bringing it into the bathtub 8 without performing troublesome installation work.

  Moreover, since the waterproof container 2 floats in water, the bathing apparatus 1 can be used in arbitrary positions on the water surface. For this reason, it can operate near a bathing person and can raise the effect of sound wave vibration, and can also move to the place which does not become an obstacle at the time of going in and out of bathtub 8. Moreover, the sound wave vibration can be switched and used in accordance with the effect and preference desired by the bather.

  Next, recording of the sound wave signal of the bathing apparatus 1 will be described.

  When recording the sound wave signal, the screws 30, 30... At the four corners of the waterproof container 2 are removed, and the waterproof container 2 is divided into an upper lid 2a and a lower container 2b. For example, a sound external input terminal of a CD (Compact Disc) player or a DVD (Digital Versatile Disc) player is connected to the sound signal input terminal 21 provided inside the waterproof container 2. Next, the power switch 11 is turned on. Next, the signal selection switch is operated to select which of the three types of sound wave signals is newly recorded. Subsequently, when the recording switch 17 is operated, recording of a signal input from the audio signal input terminal 21 is started. Next, recording is stopped again when the recording switch 17 is operated. Thus, the sound wave signal can be easily changed at home.
