As shown in FIG. 14, the mounting portions 33, 33 are provided with a substantially U-shaped projection 34 in the front view, which has a through hole 34a in the vertical direction, on the rear case front surface side 6a. A part of the screw is penetrated to the back surface of the rear case, and a screw 35 having a flat end portion 35a for retaining is screwed into the through hole 34a at a position corresponding to the through hole 34a from below the screw hole 36a. A nut member 36 supported in a closed state is interposed.
However, the case body 5 is attached to the lever attachments 33, 33 by attaching the notch 23 having a substantially U shape provided at the tip of the extension plate.
After the a and 23a are brought into contact with the screw 35 below the protrusion 34, the screw 35 is tightened, and the extension plate 23 has a notch peripheral edge portion 23b at the lower portion of the protrusion 34 and 34 by the screw 35. It is concluded.

As described above, the rear case 6 acts as a mounting base for the case body 5, and screw holes 37 for fixing the rear case with wood screws or the like are formed on the toilet wall surface in the vicinity of the four corners thereof. .

When the case body 5 is attached to the rear case 6 as described above, as shown in FIGS. 4 to 6, the lower portion 5a of the case body 5, the extension plate 23 and the lower opening 6a of the rear case 6 are attached.
Thus, an opening-shaped partition 10a is formed below, and the artificial sound generating device is configured to use the partition 10a as the battery box 10. As shown in FIG. 4, four 1.5V single batteries are used in series as shown in FIG. 4, and these four batteries 40 are housed in a cylindrical case 41 and then housed in a battery box 10. It In addition, in this battery box,
In order to energize the circuit part described later only when the battery is accommodated in the electrode direction shown in FIG. 4, for example, only when the positive electrode side protruding terminal 40a of the battery is located at the periphery of the positive electrode side terminal part. A groove or the like (not shown) is formed so as to come into contact with the terminal on the side.

The lid 42 of the opening 10a of the battery box 10 has dimensions approximately the same as the width and length of the case, and engages with the lower end 5b of the case body 5 at two positions on the left and right of the front end. Stop 42a,
Locking protrusions 42a are locked to long holes 43 formed at the lower end of the rear case 6 at two positions on the left and right of one rear side end.
b (see FIG. 6) are provided respectively.

Thus, according to the above configuration, since the battery box 10 opens downward, it is possible to easily replace the battery even in a narrow toilet booth, etc., and it is difficult to splash water for cleaning the toilet room, so water droplets etc. Is less likely to enter, and the structure can be excellent in waterproofing. Further, since the head 35b of the mounting screw 35 of the case body 5 faces the inside of the battery box 10, it is possible to improve the aesthetics and prevent the device from being stolen.

The circuit part mounting board 7 includes a control circuit 45, a memory.
46, a voice synthesizing LSI 47, an LED 48 constituting a remaining time display section, a volume adjusting volume 49 and a switch pressing rod 15 of the operation button 3 are brought into contact with each other to close a temporary circuit 50.
Figure) etc. Waveform coding (ADPCM) is adopted as the speech synthesis method in the device, and the memory 4
Reference numeral 6 stores 4-bit digitally encoded voice data, while the voice synthesis LSI 47 converts the voice data from the memory 46 into an analog voice signal. The control circuit 45 is a one-chip 4-bit microcomputer,
It controls the memory 46, the voice synthesis LSI 46 and the voice synthesis LSI 47, and also controls the drive of the LEDs 48.

The onomatopoeia generation time of the onomatopoeia generation apparatus according to this embodiment is approximately 25 seconds after the operation of the operation button 3, of which the first 2.5 seconds emits the first running water sound and the subsequent 20 seconds. It emits the sound of running water that is constantly flowing, and the power of the water gradually decreases for the last 2.5 seconds, producing the sound of running water until the water is stopped.

The LEDs 48 ... display the remaining time by gradually displaying the 25 seconds during which this onomatopoeia is generated.
After operating the operation button 3, 8 ... lights up from the LED 48a on the left side to the LED on the right side in sequence at 5 second intervals, so that the toilet user can always know the remaining time of the generated sound, which is convenient.

Further, this device operates the operation button 3 again when sound is generated, so that the water starts to flow steadily, that is, the first
It is configured to move to the state after 2.5 times from the start of the second operation (so that the first LED 48a is 2.
It lights up for 5 seconds only), and the remaining time of the generated sound can be extended at any time without any discomfort.

Further, the LED 48e at the right end of the LEDs 48 ... Is also used as a display section for notifying the life of the battery, and when the control circuit 45 detects a voltage drop more than a predetermined value of the battery, a blinking signal is given by the control circuit 45. Is emitted,
The LED 48e is configured to blink.

The above configuration is as shown in FIG. 15, for example, and the control circuit 45 operates the operation button 3
It is determined whether or not the operation is the first operation, a control signal is output to the voice synthesis LSI 47 based on the determination, the address of the memory 46 is designated, and the control circuit
The LED 48 is driven based on the clock signal of the timer in 45.

Further, the control circuit 45 is provided with a potential detecting means, constantly monitors the voltage of the battery 40 which is a power source, and when it detects that the potential falls below a certain value, it outputs a blinking signal to blink the LED 48e.

In the present embodiment, when addressing the memory 46 by the control circuit 45, the above-mentioned 20
In order to reduce the storage capacity of the memory 46, the same address is periodically designated once every 5 seconds for 4 seconds. Further, the LEDs 48 are mounted on the substrate 7 via a support base 52 so as to face the LED mounting holes 12 of the case body 5, and the mounting holes 12 are mounted via LED lenses 53. It is attached to improve the visibility and waterproof of the remaining time display.

The volume adjusting volume 49 is provided at the right end of the substrate 7 as viewed from the front so that a part thereof protrudes from the substrate 7, and the end thereof is the case body 5 as shown in FIGS. 16 to 18. Faces the opening 55 provided at the side of the. This opening
55 is provided with a rubber cap 56 for waterproofing, and the opening 55
It further prevents water from entering the case. The rubber cap 56 is attached to the opening 55 by engaging the locking hole 57 provided above the opening 55 with the locking projection 56a protruding from the rubber cap 56 and locking the same. A groove 58 provided so as to surround the opening 55 along the section.
The ridge-shaped projection 56b provided to correspond to the groove 58 is fitted to the rubber cap side. Therefore, according to such a configuration, the opening 55 for adjusting the volume is provided.
In combination with the fact that the water is provided on the side of the case where water easily flows, it is possible to prevent water from entering through the opening 55.

As shown in FIG. 2, FIG. 5, or FIG. 6, the partition plate 9 has a substantially rectangular shape so as to partition the space between the rear case 6 and the circuit part mounting board 7, and its peripheral portions 9a, 9b. , 9c, 9d are provided with a waterproof sealing material 60, the upper end edge 9a of which is the upper wall portion 5b of the case body portion 5, and the lower end edge 9b of which is the case body portion 5.
The extension plate upper surface portion 34b and a part thereof are in contact with the upper surface portion 34b of the protrusion of the mounting portion 34, and the left and right end edges 9b, 9c thereof are in contact with both left and right side walls of the case body portion 5.

In this configuration, the partition plate 9 completely prevents water droplets and the like that have entered from the rear case 6 side from further entering the circuit section, and the case body section 5 to which the circuit section mounting board 7 is attached is When it is attached to the rear case 6, it acts as a protector for protecting the circuit portion.
