DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an onomatopoeic device which is provided in a toilet room and generates onomatopoeic sounds such as running water noise.

[0002]

2. Description of the Related Art In recent years, toilet rooms equipped with onomatopoeic devices for generating onomatopoeic sounds such as running water noise have been increasing. At the time of cleaning the interior of the toilet room, washing with water using a hose is sufficiently assumed. For this reason, in the onomatopoeic device provided in the toilet room, waterproof measures are indispensable in order to prevent the device from being damaged by flooding. However, in order to ensure a constant volume, it is necessary to provide an opening in front of the speaker, and water could easily enter through the opening.

In order to solve this problem, it is conceivable to use a waterproof type which is coated on a speaker of the onomatopoeic sound generator, thereby taking measures against waterproofing in some cases.

[0004]

However, the waterproof type of the coated speaker is extremely low in use frequency as compared with the general uncoated speaker, and depending on whether the speaker is the waterproof type or not. The price of the speaker may be twice or more different and the cost is high.

[0005] The present invention is to solve the above problems,
It is an object of the present invention to provide an inexpensive onomatopoeic sound generator that is sufficiently waterproof.

[0006]

In order to achieve the above object, the present invention provides a case in which an operation switch portion and a speaker opening are formed, a back plate which can be mounted on a wall and has a groove for fixing the case, An imitation sound control board held inside the case and the back plate, and a speaker that generates an imitation sound are provided, and a vinyl sheet and a rubber packing are provided at a front portion of the speaker to prevent inundation. It is something. Thus, sufficient waterproofing measures can be taken with inexpensive components.

Further, according to the present invention, a slit is provided in a part of the rib for guiding the speaker, so that water that has entered through the speaker opening of the case is allowed to escape. As a result, unnecessary moisture can be quickly discharged from the onomatopoeic generator, and the possibility of failure can be reduced.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

As shown in the figure, the onomatopoeic device holds an internal circuit and the like in a case 1 and a back plate 2. In the case 1, a battery box 3, a dummy sound control board 4 for controlling dummy sounds such as running water noise, a speaker 5, and a dummy sound control board 4
And a mounting bracket 7 for fixing the speaker 5, a vinyl sheet 8 at the front of the speaker, and a rubber packing 9 between the vinyl sheet 8 and the case 1.

In operation, the battery box 3 and the dummy sound control board 4 can supply power to the dummy sound control board 4 by contacting the leads of metal pieces provided on each other. The dummy sound control board 4 and the speaker 5 are connected by a lead wire. When a hand is held over the infrared sensor window 12, a signal from the dummy sound control board 4 causes the speaker 5 to emit flowing water sound and at the same time operates by turning on the LED 11. Indicates the state. The flowing sound naturally fades out after flowing for a certain period of time, but can be stopped by pressing the sound stop button 13 when the sound is to be forcibly stopped.

An opening is provided in the speaker mounting portion of the case 1 to secure the volume of the flowing water sound emitted from the speaker 5. Even if water enters through the opening, water enters the speaker 5 by the vinyl sheet 8 provided at the front part of the speaker 5 and the rubber packing 9 provided between the vinyl sheet 8 and the case 1. prevent. The rubber packing 9 also plays a role in preventing the case 1 from damaging the vinyl sheet 8. The water accumulated on the front surface of the vinyl sheet 8 flows down from the slit 10 of the speaker guide rib provided to allow the water to escape. In this configuration, since the vinyl sheet 8 has a thickness of about 30 μm, there is almost no effect on running sound.

As described above, according to the onomatopoeic sound generating apparatus of the embodiment of the present invention, the vinyl sheet 8 is provided at the front of the speaker 5.
A rubber packing 9 is provided between the case 1 and the vinyl sheet 8.
Since the slits 10 for allowing water to escape are provided in the speaker guide ribs, it is not necessary to use a waterproof type coated on the speaker 5.

[0013]

As is apparent from the above description, according to the present invention, a vinyl sheet is provided at the front of the speaker, and a rubber packing is provided between the case 1 and the vinyl sheet to allow water to escape to the speaker guide ribs. Since the slit is provided, it is not necessary to use a waterproof type coated on the speaker, and an inexpensive onomatopoeia generator can be provided.
