Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a device for generating a sound of flowing water (hereinafter referred to as “water flow sound”), and more particularly, to a sound of urinating in a toilet (hereinafter referred to as “stool sound”). The present invention relates to a device for generating a water flow sound for drowning.

[0002]

[Prior art]

 It is often embarrassing to be heard by others about the stool sound generated when using stools in toilets, especially for women. For this reason, when entering a private room (for women and men's stools), flushing water for flushing the toilet bowl may be generated to make the sound of the water flow and to eliminate the stool sound.

[0003]

[Problems to be solved by the invention]

 However, the rinsing water used to generate the rinsing sound is not used to fulfill the original purpose of rinsing the toilet, but is merely used to generate a sound, and waste water resources. There was a problem of using it. In order to reduce such waste, some toilets are equipped with a device that generates the sound of running water.However, doing so for all toilets is enormous and requires a lot of noise. There is also a problem that it is wasteful to do so for all toilets because there is a large difference between individuals whether or not they care.

Accordingly, an object of the present invention is to provide a device that allows a person who is worried about stool noise to freely generate a water flow sound when necessary without wasting water resources.

[0005]

[Means for Solving the Problems]

 The device of the present invention (hereinafter referred to as “the device”) includes a storage unit that stores a sound signal of flowing water, a switch that generates an electric start signal when operated, and the start signal. And a reproducing unit that reproduces the sound signal stored in the storage unit when receiving the sound. In this device, the storage unit stores a signal of a sound of flowing water (water flow sound). The switch generates an electrical start signal when operated (eg, pressed). Upon receiving the start signal generated by the switch, the reproduction unit reproduces the water flow sound signal stored in the storage unit. In this way, if the portable device, that is, the portable device is carried, the reproduction unit reproduces the water flow sound stored in the storage unit by operating the switch. Water noise can be freely generated when needed without wasting resources. Therefore, if the person who is worried about the stool sounds carries this device, the switch can be operated at the time of stool and the water flow sound can be generated without wasting water resources. It can be used comfortably without worrying.

[0006] The water flow noise generated by the present device can be any sound as long as it is not unnatural, and can be any sound that is not unnatural. It is preferable to give a natural feeling to both the user of the device and the person who hears the sound generated by the device around the device.

[0007] The storage unit of the present device may be any type of device that stores the signal of the water flow sound and that the reproduction unit can reproduce the signal. For example, an IC that has been frequently used in the related art can be used. A memory, a tape recorder, a floppy disk, a compact disk (CD), a mini disk (MD) or the like may be used. At this time, the device may generate one type of water flow noise, but may also use two or more types of water flow noises. can do. Furthermore, the water flow sound generated by this device may be freely changed by the user of this device. In this case, a rewritable device is used for the storage unit, and a new water flow sound is input to them. An input unit including a microphone or the like may be provided.

[0008] The switch of the device may be any switch that generates an electrical start signal when actuated, for example, a push button switch, a rotary switch, a knife switch, a slide switch, a micro switch. Switches and the like.

[0009] The reproduction unit of the present apparatus is not particularly limited as long as it receives the start signal generated by the switch and reproduces the water flow sound signal stored in the storage unit. Normally, upon receiving the start signal, the playback unit amplifies the water flow sound signal stored in the storage unit and supplies the amplified water flow sound signal to a speaker that is a part of the reproduction unit, thereby reproducing the water flow sound signal. . It goes without saying that the volume of the water flow sound to be reproduced can be adjusted.

[0010] The timing of stopping the generation of the water flow sound of the present apparatus may be determined in various ways. For example, even when it is detected that the switch is operated again, the generation of the water flow sound is also started. May be performed when a predetermined time has elapsed since the start of the process, or when a series of water sounds stored in the storage unit are reproduced a predetermined number of times.

[0011] Since it is assumed that moisture adheres or infiltrates into the water, the present device may have a waterproof function so as not to break down even in such a case. Here, the “waterproof function” refers to a function in which the water does not enter the storage unit or the regenerating unit even if water adheres to the outer surface of the device. Preferably, the water-proof function is such that the water does not enter the storage unit or the regenerating unit even if the apparatus is sneaked for several minutes in water having a depth of about several tens cm.

The present apparatus is often portable, that is, usually carried. Therefore, in order to prevent the apparatus from dropping or being lost and to make it easier to carry, a suspending member may be attached. The term “suspension member” as used herein broadly includes those capable of holding the apparatus in a suspended state by gripping it, and includes, for example, suspension strings, suspension rings, suspension chains, and the like.

[0013]

[Embodiment of the invention]

 Embodiments of the present invention will be described in detail with reference to the drawings, but the present invention is not limited thereto.

FIG. 1 is a perspective view showing an external configuration of the apparatus of the first embodiment. With reference to FIG. 1, the external configuration of the present apparatus 11 will be described. The present apparatus 11 includes an apparatus main body 21 and a suspension chain 31 which is a suspension member attached to the apparatus main body 21. Here, the device body 21 is a box having a substantially rectangular parallelepiped shape, and is formed of a resin material. However, the present invention is not particularly limited thereto. It may be a prism, a sphere, an oval, a tetrahedron, or the like, and the material may be a timber, paper, a metal material such as stainless steel, or an inorganic material such as marble or concrete. The size of the apparatus main body 21 is approximately 5 cm × 8 cm × 1.5 cm, and the weight is about 100 g, so that it can be freely carried and does not interfere with carrying. Of course, these dimensions (size) and weight are not limited to these, and may be larger or smaller, and may be heavier or lighter as long as they are portable.

On one surface of the substantially rectangular parallelepiped formed by the apparatus main body 21, a push button switch 41 for starting generation of a water flow sound (in this case, a flush sound of a flush toilet) is attached. The push button switch 41 generates an electric start signal when pressed (operated). A speaker 61 is mounted on another surface of the substantially rectangular parallelepiped formed by the device main body 21. The speaker 61 generates a water flow sound as described later. In addition, on the back surface of the other surface of the substantially rectangular parallelepiped formed by the device main body 21, an exchange port for exchanging a battery serving as a power source of the device 11 is formed (not shown). On the other hand, the suspension chain 31 is a metal (stainless steel) chain, and is formed by three rings. One of the three rings, which is located on one end side of the suspension chain 31, is passed through a suspension portion 23 formed at a corner of the apparatus main body 21, and the one ring has the same size. It is connected to a ring which is larger than these two rings and is located on the other end side of the suspension chain 31 via the ring of the suspension. For this reason, the device 11 can be easily suspended and fixed by gripping the suspension chain 31 or hooking any of the three rings constituting the suspension chain 31. The device body 21 has a waterproof function. Even if the device body 21 is accidentally dropped into a basin inside the flush toilet and sneaks into water, the water does not enter the box body of the device body 21 for about 10 minutes. It has a structure.

FIG. 2 is a circuit block diagram of the device 11 shown in FIG. The circuit configuration of the device 11 will be described with reference to FIG. The device 11 includes an IC memory circuit 81 as a storage unit for storing a signal of a flushing sound of a flush toilet, a switch 55 for generating an electric start signal when operated, and an IC for receiving the start signal. A reproducing unit 69 for reproducing the signal of the washing sound stored in the memory circuit 81 (storage unit), and a counter circuit 84 for stopping the signal of the washing sound after a certain period of time. .

An IC memory circuit 81 serving as a storage unit stores a signal of a flush sound of a flush toilet that is a flush sound.

The switch 55 includes the push button switch 41 and the trigger generation circuit 53. When the push button switch 41 is pressed (operated), it is converted into an electric signal, and the electric signal is sent to the trigger generation circuit 53. The trigger generation circuit 53 generates an electric start signal (trigger) to the reproducing unit 69 by an electric signal (corresponding to the press of the push button switch 41) sent from the push button switch 41.

The reproducing section 69 includes a flip-flop circuit 63, a relay 65, a DA converter 66, an amplifier 67, and a speaker 61. When the flip-flop circuit 63 receives the input of the start signal (trigger) issued from the switch 55 (trigger generation circuit 53), the relay 65 is turned on (ON state), and in this operation state, the flip-flop circuit is further turned on. When the circuit 63 receives an input of a trigger from the trigger generation circuit 53, the relay 65 goes into a pause state (OFF state). When the relay 65 is in the operating state (ON state), the IC memory circuit 81 serving as a storage unit outputs the stored contents as a digital signal to the DA conversion circuit 66, and the relay 65 is in the rest state (OFF state). In this case, the IC memory circuit 81 does not output the stored contents. The digital signal is converted into an analog signal by a DA converter 66. The analog signal is amplified by the amplifier circuit 67 to an extent sufficient to drive the speaker 61, and then converted from the electrical signal to sound waves by the speaker 61. It should be noted that the magnitude of the washing sound reproduced may be changed by changing the amplification factor of the amplifier circuit 67.

When the counter circuit 84 receives the start signal (hereinafter referred to as “start trigger” in this paragraph) issued from the switch 55 (trigger generation circuit 53) to the flip-flop circuit 63, the counter circuit 84 starts counting and waits for a predetermined time. When the time elapses, a trigger (hereinafter, referred to as “end trigger” in this paragraph) is generated in the trigger generation circuit 53. When the end trigger is received by the flip-flop circuit 63, the relay 65 is put into a rest state (OFF state), and the output of the digital signal from the IC memory circuit 81 is stopped. As a result, a start trigger is issued and the reproduction of the water flow sound is started. After the predetermined time has elapsed, an end trigger is generated and the reproduction of the water flow sound is terminated.

If it is desired to stop the reproduction of the water flow sound before the predetermined time elapses, a trigger is generated in the trigger generation circuit 53 by pressing the push button switch 41, and the relay 65 is set in the pause state. (OFF state). Conversely, after the predetermined time has elapsed and the reproduction of the water flow sound has been completed, if it is desired to continue the reproduction of the water flow sound, the trigger is generated in the trigger generation circuit 53 by pressing the push button switch 41 again. What is necessary is just to make the relay 65 into an operation state (ON state).

Since the present apparatus 11 is configured as described above, if the push button switch 41 is pressed (operated) when the user uses the toilet in a toilet or the like, the push button switch 41 will be notified of the pressing by an electric signal. And sends it to the trigger generation circuit 53. The trigger generation circuit 53 generates a start signal to the reproduction section 69 (the flip-flop circuit 63). When the flip-flop circuit 63 receives the start signal (trigger) input from the switch 55 (trigger generation circuit 53), the relay 65 is turned on (ON state), and the IC memory circuit 81 stores the stored data. The thus-washed sound signal is output as a digital signal to the DA conversion circuit 66, and is converted into an analog signal by the DA conversion circuit 66. The converted analog signal is amplified by the amplifier circuit 67, and the speaker 61 emits a washing sound.

Therefore, if a person who does not want to hear his or her urine sound by others carries this device 11, he / she can press the push button switch 41 when he / she urinates in a toilet or the like. Without wasting water resources (without flowing real water), the sound of water flow can be freely generated, so that the noise of the stool can be eliminated. It can be used comfortably without doing.
