Therefore, there were problems such as shortening the sound recording time and lowering the sound quality. In addition, reduction of similar sounds of different volumes was not considered only by dividing and reproducing one sound repeatedly. Therefore, the present invention is intended to solve such a problem, in which the volume of one audio data is varied and processed by performing multi-step volume adjustment with a PWM signal, and as if different sounds are created. Therefore, the voice recording data stored in the memory of the voice synthesis IC can be reduced.

At the time of reproduction, the control unit sends a volume adjustment signal to the voice synthesis unit to fade out the volume, thereby artificially generating voice data at which the running water sound ends. As a result, the recorded sound of the flowing water sound is processed to create the end sound of the flowing water sound, so that the recording capacity of the audio data can be reduced.

In order to solve the above problems, a second aspect of the present invention is the toilet seat device according to the first aspect, wherein the control unit causes the voice synthesizer to input an address for starting voice data reproduction and a control signal for starting voice reproduction.

According to a sixth aspect of the present invention, in order to solve the above-mentioned problems, in the toilet seat device according to the fifth aspect, while the flow sound data is being reproduced by the voice synthesizing unit, acceptance of the toilet flush switch is suspended and the flow of the flush water is held. It is characterized in that the reproduction of the voice data which ends is started at the voice synthesizer. As a result, the acceptance of the toilet flush switch is considered as the end of the user's toilet, and if the current running sound is flowing, it is switched to the ending sound of the running water, so that the unnecessary running water sound is stopped immediately or the running water sound reproduction time Power saving and usability are improved by shortening.

According to a seventh aspect of the present invention, in order to solve the above-mentioned problems, in the toilet seat device according to the fifth aspect, when the reproduction of the voice data for ending the running water is completed at the voice synthesizing unit, the suspended toilet cleaning switch is effective. It is characterized by restarting the toilet cleaning operation. As a result, since the flushing sound ends and the toilet flushing operation is performed, even if the toilet flushing switch is pressed several times, the toilet flushing operation is surely performed once, so that water saving is improved.

3 and 3. Detailed voice generation operation will be described later.

First, the seating sensor 12 and the detachable sensor 1
The configuration of No. 3 will be described. FIG. 2 shows a human body detecting means provided with a seating sensor 12 for detecting the presence or absence of a user, that is, a human body sitting on the toilet seat 29. As shown in FIG. 2, the seating sensor 12 emits infrared rays in front of the sanitary washing device main body 14, and detects whether or not the user is seated based on the reception of the reflected light. The seating sensor 12 outputs an "OFF" signal to the control circuit 1 when the human body is not detected, and outputs an "ON" signal to the control circuit 1 when the human body is detected.

The attachment / detachment sensor 13 is installed in the lower part of the sanitary washing device main body 14 and comprises a hall IC and a magnet 17 provided in the toilet bowl. The sanitary washing device main body portion 14 is attached to the toilet bowl 22. When it is present, the magnetic field around the Hall IC is changed by the magnet 17 so that the output of the attachment / detachment sensor 13 is changed to detect whether or not the sanitary washing device body 14 and the toilet 22 are attached / detached. When the sanitary washing device body 14 is not attached to the toilet 22, the attachment / detachment sensor 13 outputs an "OFF" signal, and when the sanitary washing device body 14 is attached to the toilet 22, a control signal is an "ON" signal. Output to 1.

Next, the voice synthesis IC 4 will be described. As shown in FIG. 4, the voice synthesizing IC 4 has a voice start input terminal 18 for receiving a voice synthesizing operation start command signal sent from the control circuit 1, and address designation of voice data sent from the control circuit. , An address input terminal 19 for taking in the command signal, an audio output terminal 20 for converting the digitized audio data stored in the memory into an analog audio signal and outputting the analog audio signal to the amplifier circuit, and an input analog voltage value. The volume setting input terminal 21 capable of changing the signal related to the volume of the audio signal output to the amplifier circuit by
It has and.

In the prior art, in order to reproduce the toilet cleaning sound, as shown in FIG. 3 (A), the sound data of the rising sound is stored in the address "01" and the sound of the intermediate sound is stored in the address "11". The data, the voice data of the falling sound was stored in the address "10". The rising sound is a sound in which the sound of the flush valve operating at the start of the toilet cleaning operation and the sound of the toilet cleaning water starting to flow vigorously are overlapped. The intermediate sound is a sound in which the toilet flush water is constantly flowing. The falling sound is the sound until the toilet flush water gradually loses its momentum and finally stops.
In the conventional technique, a toilet flushing sound is artificially generated by sequentially generating three sound data of a rising sound, an intermediate sound, and a falling sound from the speaker 7.

In this embodiment, as shown in FIG. 3B, in the memory section 2 of the voice synthesis IC 4, two voice data, that is, the rising sound at the address "01" and the intermediate sound at the address "11" are stored. I memorized it, not the three audio data,
The sound generation operation is performed with the two sound data to realize the toilet cleaning sound. The operation of voice generation will be described based on FIGS. 3, 4, and 5. In this embodiment, the addresses "01" and "11" in the memory unit 2 of the voice synthesis IC 4 are 2.
Voice data for 5 seconds is stored. When the attachment / detachment sensor 13 outputs an “ON” signal to the control circuit 1, that is, when the sanitary washing device main body 14 is attached to the toilet 22, when the artificial sound generating operation switch 8 is pressed, the artificial sound generating operation starts. Is inputted to the control circuit 1, a command signal for starting the voice synthesis operation is sent from the control circuit 1 to the voice start input terminal 18 of the voice synthesis IC 4, and further stored in the memory section 2 of the voice synthesis IC 4 to the address input terminal 19. Address "01" of voice data
Is sent. Then, analog voice data of the rising sound is output from the voice output terminal 20 of the voice synthesizing IC 4 to the amplifying circuit 5, the voice data is amplified by the amplifying circuit 5, and the rising sound is generated from the speaker 7. As shown in FIG. 5, after the rising sound is generated for 2.5 seconds, the intermediate sound is continuously generated. At that time, the address "11" of the voice data is input from the control circuit 1 to the address input terminal 19 of the voice synthesis IC 4. The specified signal is sent. The signal designating "11" is sent eight times in succession, and the intermediate tone is generated for a total of 20 seconds. After the generation of the intermediate sound, the falling sound continues for 2.5 seconds. Here, the falling sound is realized by using the intermediate sound data “11”. The sound volume setting input terminal 21 is used to realize the falling sound with the sound data "11" of the intermediate sound. For that purpose, first, the sound volume setting input terminal 21 of the speech synthesis IC 4 will be described below.

While the artificial sound is being generated, the PWM output terminal 23 of the control circuit 1 outputs a certain ON-duty pulse signal as shown in FIG. The PWM output terminal 23 can output various ON-duty pulse signals by control. The output pulse signal is smoothed by the resistor 24 and the capacitor 25 and converted into a constant analog voltage value. The converted voltage is input to the volume setting input terminal 21 of the voice synthesizing IC 4, and the voice synthesizing IC 4 outputs an analog voice signal corresponding to the voltage value input to the volume setting input terminal 21 from the voice output terminal 20 to the amplifier circuit 5. Is output, and the volume of the onomatopoeia generated from the speaker 7 is determined. When the analog voltage value input to the volume setting input terminal 21 changes, the volume of the onomatopoeia generated from the speaker 7 also changes.

The diode 26 is the volume setting input terminal 2
This is for protecting the voice synthesizing IC 4 so that a voltage exceeding 1 is not applied to the reference voltage value.

While the voice synthesis IC 4 is outputting the intermediate tone analog voice data to the amplifier circuit 5, the falling tone is formed by changing the analog voltage value input to the volume setting input terminal 21. The details will be described below. While the voice synthesis IC 4 is outputting the intermediate voice analog voice data to the amplifier circuit 5, the ON duty time output from the PWM output terminal 23 of the control circuit 1 is shown in FIG.
A (ON duty: 75%) → B (ON duty: 50%) → C (ON duty: 25%) → D
Decrease in the order of (ON duty: 0%). Then, the analog voltage value input to the volume setting input terminal 21 of the voice synthesis IC 4 also decreases in the order of A ′ → B ′ → C ′ → D ′. When the analog voltage value input to the volume setting input terminal 21 decreases and the volume of the intermediate sound emitted from the speaker 7 gradually decreases, and the ON duty becomes “D”. That is, the sound generation stops when the pulse signal is no longer output, and when the sound generated from the speaker is heard in the order of A → B → C → D, the toilet flush water gradually increases as shown in FIG. You can hear the sound until the water finally stops, that is, the falling sound. In this way, the falling sound can be realized by using the intermediate sound data “11”.

In the present embodiment, the ON duty of the PWM output terminal 23 has four stages of A → B → C → D, but it may be increased from four stages in order to make the sound connection more natural. Further, instead of decreasing the volume level in proportion to the time as shown in FIG. 8, the ON duty of the PWM output terminal 23 is changed as shown in FIG. As shown in, the curve becomes smaller, and a sound that is more comfortable to the human ear can be realized.

In the prior art, three types of sound data of rising sound, sound data of intermediate sound, and sound data of falling sound were required in order to artificially generate the toilet cleaning sound. In the example, the falling sound can be realized by changing the volume of the intermediate sound.
It is not necessary to specially store the sound data of the falling sound in the memory unit 2 of 4, and the pseudo sound of the toilet cleaning sound can be formed and generated with a small memory.

In this embodiment, the rising noise is 2.5
Although the intermediate sound is generated for 20 seconds and the falling sound is generated for 2.5 seconds, the sound generation time may be changed depending on the usage situation in the field.

Further, in this embodiment, the setting of the volume is realized by utilizing the PWM output terminal 23. The volume setting mechanism will be described with reference to FIGS. 4, 6, 11, and 12. As described above, while the artificial sound is being generated, the PWM output terminal 23 of the control circuit 1 is turned on as shown in FIG.
The duty pulse signal is output. The output pulse signal is a resistor 24 and a capacitor 25 as shown in FIG.
Is smoothed and converted into a constant analog voltage value. The converted voltage is input to the volume setting input terminal 21 of the voice synthesizing IC 4, and the voice synthesizing IC 4 outputs an analog voice signal corresponding to the voltage value input to the volume setting input terminal 21 from the voice output terminal 20 to the amplifier circuit 5. Is output,
The volume of the onomatopoeia generated from the speaker 7 is determined. If the analog voltage value input to the volume setting input terminal 21 changes, the volume and volume of the onomatopoeia generated from the speaker 7 also change.

While the artificial sound is being generated, if the loud sound volume switch 9 provided on the operation unit 11 is pressed once, a command signal to increase the sound volume by one step is input to the control circuit 1, As shown in, the control circuit 1 turns on the pulse signal output from the PWM output terminal 23.
Increase the duty by one step. The control circuit 1 controls the ratio of ON duty that is increased in one step. Then, the analog voltage value smoothed by the resistor 24 and the capacitor 25 also increases, and as a result, the analog voltage value input to the volume setting input terminal 21 of the voice synthesis IC 4 increases, so that the volume of the pseudo sound generated from the speaker 7 is 1. It increases by the amount of steps. If the volume switch 9 is pushed further, the ON duty of the pulse signal output from the PWM output terminal 23 increases according to the number of times the switch is pushed, and the volume of the artificial sound generated from the speaker 7 increases. .

While the onomatopoeia is being generated, the operation unit 11
When the small volume switch 10 provided in is pressed once, a command signal for lowering the volume level by one step is input to the control circuit 1, and the control circuit 1 outputs from the PWM output terminal 23 as shown in FIG. The ON duty ratio of the pulse signal being output is reduced by one step. The control circuit 1 controls the ON duty ratio that is reduced in one step. Then, the analog voltage value smoothed by the resistor 24 and the capacitor 25 also becomes small,
As a result, the analog voltage value input to the volume setting input terminal 21 of the voice synthesis IC 4 is reduced, so that the volume of the onomatopoeia generated from the speaker 7 is reduced by one step. If you press the volume small switch 10 further, depending on the number of times it is pressed
The ON duty of the pulse signal output from the PWM output terminal 23 decreases, and the volume of the artificial sound generated from the speaker 7 decreases. The control circuit 1 can freely set how many steps are provided on the side of increasing the volume and on the side of decreasing the volume, and to what extent the ON duty is changed.

In this embodiment, the PWM output terminal 23 is turned on.
Volume setting input terminal 21 when the duty becomes large
The analog input voltage value to the volume setting input terminal 21 is reduced when the ON duty of the PWM output terminal 23 becomes small, but the inverter may be changed depending on the characteristics of the voice synthesis IC 4. The relationship between the ON duty and the analog voltage value may be reversed by inserting the PWM output terminal 23 and the resistor 24 between them.

Next, the relationship between the seating sensor 12 and the artificial sound generating operation will be described. Here, when the seating sensor 12 emits infrared light, the seated sensor 12 emits infrared light, so that the current consumption temporarily increases and the power supply voltage largely fluctuates. If the power source of the amplifier circuit 5 is the same as the power source of the seating sensor 12, a noise signal is output from the amplifier circuit 5 to the speaker 7 at the moment when the power source voltage fluctuates,
As a result, an abnormal noise is generated in synchronization with the infrared emission timing of the seating sensor 12 from the speaker 7. In this embodiment, as a countermeasure, a diode 27 is inserted in the power supply line of the amplifier circuit 5 as shown in FIG. Even if the power supply voltage greatly fluctuates due to the seating sensor 12, the power supply voltage to the amplifier circuit 5 is rectified by the diode 27.
It is possible to minimize the generation of abnormal noise.

When the seating sensor 12 detects the separation of the human body while an intermediate sound is being generated, that is, the seating sensor 12 indicates "OF".
When the "F" signal is output to the control circuit 1, the control circuit 1 shifts to the control for generating the falling sound without waiting for the generation of the intermediate sound for 20 seconds as shown in FIG. After the falling sound is generated for 2.5 seconds, the voice generating operation is ended.

The seating sensor 12 while the rising sound is generated
When the person detects the separation of the human body, as shown in FIG. 14, the control circuit 1 controls the generation of the intermediate sound after the rising sound is generated, that is, after the rising sound is generated for 2.5 seconds. Instead, the control shifts to the control for generating the falling sound. After the falling sound is generated for 2.5 seconds, the voice generating operation is ended. Here, when the control is shifted to the falling sound, the intermediate sound may be sounded for several seconds and then the falling sound may be generated in order to connect the sounds more naturally.

The seating sensor 12 while the falling sound is generated
When the person detects the sitting of the human body, as shown in FIG. 15, the control circuit 1 directly performs the control to generate the falling sound. That is, the control of the control circuit 1 is not changed even when the seating sensor 12 detects the seating while the falling sound is generated. When a falling sound is generated, the seating sensor 12 "O
The control circuit 1 may be controlled not to accept the output of the “FF” signal.

As described above, when the user does not need to generate onomatopoeia by controlling the PWM output terminal 23 depending on the seating sensor 12 and the state of onomatopoeia generation, that is, when the user leaves the toilet seat with a need. Can stop the generation of onomatopoeia naturally. Further, as shown in FIG. 16, when the seating sensor 12 once detects the seating and then immediately detects the seating, the control of the control circuit 1 is changed from the control of the falling sound to the control of the intermediate sound. Good.
When shifting from the control that generates the falling sound to the control that generates the intermediate sound, the PWM output terminal 2 of the voice synthesis IC 4
The ON duty of 3 may be suddenly changed to the ON duty when the intermediate sound is generated. However, in order to make the connection of the sounds more natural, the ON duty is set to the ON duty opposite to the control when the falling sound is generated. May be gradually increased and finally changed to the ON duty when the intermediate sound is generated.

Next, the operation when the toilet bowl cleaning function is provided will be described below. The block diagram is shown in FIG. The operation unit 11 has a toilet flush switch 2 for operating the toilet flush function.
8 and the signal of the toilet flush switch 28 is input to the control circuit 1.

When the toilet flush switch 28 is pressed while an intermediate tone is being generated, that is, when a signal for starting the toilet flushing operation is input to the control circuit 1, the control circuit 1 outputs an intermediate tone of 20 as shown in FIG. The control shifts to control for generating a falling sound without waiting for generation for a second. And
After the falling sound is generated for 2.5 seconds, the sound generating operation is ended, and after the artificial sound is stopped, the toilet cleaning operation is started.

When the signal for starting the toilet bowl cleaning operation is input to the control circuit 1 while the rising sound is being generated, the control circuit, as shown in FIG. After the sound has been generated for a second, the control shifts to the control to generate the falling sound without controlling to generate the intermediate sound. Then, after the falling sound is generated for 2.5 seconds, the sound generating operation is ended, and after the artificial sound is stopped, the toilet cleaning operation is started.

When a signal for starting the toilet flushing operation is input to the control circuit 1 while the falling sound is being generated, FIG.
As shown in, the control circuit 1 controls to generate the falling sound as it is, and ends the sound generation operation,
After the imitation is stopped, the toilet cleaning operation is started. In this way, when the user does not need to generate the artificial sound by controlling the PWM output terminal 23 depending on the artificial sound generation state when the toilet wash switch 28 is pressed, that is, when the user leaves the toilet seat with a need. Occurrence of onomatopoeia can be stopped naturally.

The present invention has the following effects due to the above configuration.

According to the present invention, there is provided a memory section for storing the AD-converted flowing water sound data, a voice synthesizing section for D / A converting the flowing water sound data, and a voice amplifying section for amplifying the output of the voice synthesizing section. An amplification circuit provided, a speaker that generates running water sound, a seating detection unit that detects seating of a human body and outputs a sitting signal, and an operation unit that operates generation / stop of the running water sound,
In a toilet seat device including a control section for receiving the seating signal and an operation signal to output a control signal for the voice synthesizing section, when the running water sound data of the memory section is reproduced by the voice synthesizing section, the control section is A volume adjustment signal is sent to the voice synthesizer to fade out the volume, and the voice data at which the running water sound ends is generated artificially. As a result, the recorded sound of the flowing water sound is processed to create the end sound of the flowing water sound, so that the recording capacity of the audio data can be reduced.

According to a second aspect, in the toilet seat device according to the first aspect, the control section has an address input for starting reproduction of voice data and a control signal for starting voice reproduction to the voice synthesis section, Since the adjustment signal is composed of the PWM signal, the volume of the sound being generated can be arbitrarily changed by controlling the PWM signal by the control unit. As a result, by controlling the PWM signal by the control unit, the control unit can arbitrarily change the volume of the sound being generated, and various sounds can be created.

According to a third aspect of the present invention, in the toilet seat device according to the first or second aspect, the volume adjustment signal divides the ON duty of the PWM signal into multiple stages, so that the volume of the sound changes depending on each ON duty ratio. Therefore, the volume of the generated sound can be arbitrarily changed. as a result,
Since the control unit controls the PWM signal to change the volume of the sound in multiple stages depending on the ON duty ratio, it is possible to make a finer volume change and to obtain a natural processed sound.

According to a fourth aspect of the present invention, in the toilet seat device according to the first aspect, when the output of the seating signal changes from ON to OFF, the reproduction of the voice data ending the running water is started in the voice synthesizer. Thus, when the user no longer needs the toilet flushing sound, that is, when the user finishes using the toilet and leaves the toilet seat, it is possible to quickly end the generation of the onomatopoeia and to fade out the volume. Then, the sound data at which the running water sound ends is generated artificially. As a result, when the seating signal is turned off, the sound of ending the running water sound is generated, which is regarded as the end of the user's urine, and the unnecessary running water sound can be stopped immediately. And the usability is improved.

According to a fifth aspect of the present invention, in the toilet seat device according to the first aspect, the toilet seat has a toilet flushing function for flowing cleaning water to perform toilet flushing, and the operating portion has a toilet flush switch for operating the toilet flushing function. While playing the running water sound data in the voice synthesizer, the toilet cleaning switch suspends the reception and suspends the toilet cleaning operation, so that the artificial sound is faded out while the artificial sound is generated. Until the generation of the onomatopoeia ends, it is prohibited to flush the toilet flush water in order to eliminate the sound that the user is using even though the onomatopoeia is being generated, to promote the water saving effect. be able to. In other words, the user's toilet sound can be sufficiently masked while the running water sound is being reproduced, so that water can be saved by suspending unnecessary toilet cleaning that was operated without knowing it.

According to a sixth aspect of the present invention, in the toilet seat device according to the fifth aspect, while the sound synthesizing section is reproducing the running water sound data, the acceptance of the toilet flush switch is suspended and the sound data ending the running water is reproduced. By starting with the voice synthesizing unit, the generation of the onomatopoeia can be promptly ended when the user wants to actually wash the toilet bowl. In other words, the acceptance of the toilet flush switch is regarded as the end of the user's toilet, and if the current running sound is currently flowing, it is switched to the ending sound of the running water, so that the unnecessary running water sound is stopped immediately or the running water sound playback time Power saving and usability are improved by shortening.

According to a seventh aspect of the present invention, in the toilet seat device according to the fifth aspect, when the reproduction of the voice data for ending the running water is finished in the voice synthesizing section, the held toilet flush switch is enabled and the toilet flush operation is restarted. By doing so, when the user no longer needs to generate the onomatopoeia, that is, when the volume of the onomatopoeia fades out and the generation of the onomatopoeia ends, the toilet flushing operation can be started. It is possible to suppress water consumption and promote a water saving effect. That is, since the toilet flushing operation is performed when the sound of running water is finished, even if the toilet flushing switch is pressed several times, the toilet flushing operation is surely performed once, so that water saving is improved.
