Abstract

PURPOSE:To prevent erroneous actuation by actuating a voice generating device with signals from a comparator means for outputting a signal according to changes in illuminances of a vicinity illuminance detection sensor and an environment illuminance measurement sensor, and from a comparator means for outputting a signal according to the change in the measurement sensor. CONSTITUTION:When a user's hand interrupts the sensing light of a vicinity illuminance detection sensor 3, the resistance of the sensor 3 increases, the voltage at the point A decreases and is applied to the negative pole of a comparator means A 14. When the illuminance around an environment illuminance measurement sensor 4 is sufficient, the voltage at the point A applied to the positive pole of the comparator means 14 becomes higher than the voltage at the point B, and the signal from the comparator means 14 is inputted to a control element 5. A voltage of the point C generated in a resistance 12 is applied to the negative pole of a comparator means B 13 having the function of detecting illuminance below a certain level and a signal is inputted from the comparator means 13 to the element 5. Further, a voice synthesis LSI 6 causes the signal from the element 5 to draw out synthesized voice data from a ROM 7, synthesize a voice, and generate the voice from a speaker 10. Or, when a switch 2 is operated, the voice is produced from the speaker 10 irrespective of the sensors 3, 4.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a speech synthesis device that generates onomatopoeic sounds that camouflage, for example, the sound of using a toilet.

2. Description of the Related Art Conventionally, devices using this type of speech synthesis have been disclosed in Japanese Utility Model Application Publication No. 57-198999 and Japanese Utility Model Application Publication No. 60-18173.
As proposed in the publication, an onomatopoeic sound generating device that generates an onomatopoeic sound that camouflages the sound of using the toilet while using the toilet, and a switch that drives this device are installed in the toilet, especially when women are using the toilet while using the toilet. In order to avoid having people hear the sound of urination, there is a device that generates the above-mentioned onomatopoeic sound by manually operating this switch when urinating. is manipulated, giving the user a sense of uncleanness.

In order to eliminate this sense of uncleanness, we developed a device that generates onomatopoeic sounds without manually operating a switch.
As proposed in No. 00, there is also an onomatopoeic sound generating device that generates an onomatopoeic sound that camouflages the sound of using a toilet while using a toilet via a foot-operated switch.

Furthermore, Utility Model Application Publication No. 60-14349 was developed as an onomatopoeic sound generating device that camouflages the sound of using a toilet while defecating using a manual method or other means than a foot-operated switch.
As shown in one embodiment of Publication No. 7, there is an onomatopoeic sound generating device that uses a proximity switch to generate an onomatopoeic sound that camouflages the sound of using a toilet while using the toilet, and other embodiments and implementations of Publication No. 143497/1982. As proposed in Japanese Patent Publication No. 62-31180, photoelectric devices as non-contact sensors that are electrically connected to each other when there is no shield are installed at corresponding parts of the side walls of the toilet room, and photoelectric devices are installed as non-contact sensors that are electrically connected to each other when there is no shielding object. There is a device that emits a sound that imitates the sound of a water washer through a sound generator when the conduction between the devices is blocked, and camouflages the sound of urination during urination with the sound of the water washer. Other possible non-contact sensors include infrared pyroelectric sensors, sensors that utilize reflected ultrasonic waves, and sensors that detect changes in capacitance.

Problems to be Solved by the Invention However, all such non-contact sensors are expensive;
It was not practical for use in low-cost products such as onomatopoeia generators.

On the other hand, there is a relatively low-cost sensor that uses a CdS element that can detect changes in illuminance to detect changes in illuminance when a person places their hand over a switch (using the photoelectric device described above). However, devices using such photoelectric sensors tend to malfunction due to ambient light, and may also be affected by changes in illuminance around the sensor installation site or by turning lights on and off.
However, there are many unstable factors such as the drive switch of the onomatopoeic sound generating device operating, and when the illuminance around the sensor installation site is below a certain level, the sound generating device continues to emit sound. There was a problem that I couldn't answer.

Means for Solving the Problems The present invention has been made to eliminate the above-mentioned problems, and includes a proximity illuminance detection sensor that detects illuminance that changes due to the approach of a human body or an object, and a proximity illuminance detection sensor that detects illuminance in the environment of the installation site. An environmental illuminance measuring sensor that measures, a comparing means A that outputs a signal according to changes in illuminance of both of these sensors, and a comparing means B that outputs a signal according to changes in the environmental illuminance measuring sensor.

A sounding device that operates when there are output signals from both comparing means A and B, and a drive switch that can be operated by operating this sounding device independently of the signal output from both comparing means A and B are provided in the main body of the device. The proximity illuminance detection sensor and the environmental illuminance measurement sensor are arranged at different positions on the main body of the device, and the comparison means B detects illuminance below a certain level in the environment of the installation site via the environmental illuminance measurement sensor. It is designed to have a function.

Operation By doing this, the sounding device can be used as both comparison means A,
Since it operates only when there is an output signal from B, when the illuminance around the environmental illuminance measurement sensor installation site is below a certain level, when the comparing means B does not output a signal that drives the operation of the sound generating device, only the comparing means A is activated. Even if there is an output signal from the output signal, the audio generator will not be driven.

Example An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2 showing the configuration of the embodiment, 1 is the main body of the device, for example, inside a toilet (not shown) that is within easy reach of the user when the user takes a toilet posture. is attached to. Reference numeral 2 denotes a moving switch, which is provided in the main body 1 of the device and drives the sound generation device (hereinafter referred to as a speaker) 10, which will be described later.

3 and 4 are a proximity illuminance detection sensor and an environmental illuminance measurement sensor made of CdS, respectively, and are installed at different positions in the main body 1 of the device, and both sensors 3 and 4 increase in resistance value when the sensing light is interrupted. The proximity illuminance detection sensor 3 detects the illuminance that changes due to the approach of a human body or an object, and the environmental illuminance measurement sensor 4 measures the illuminance in the environment of the installation site. Reference numeral 14 denotes comparison means A consisting of a comparator, and the e-pole includes a resistor R of which constitutes a bridge circuit consisting of an environmental illuminance measurement sensor 4, a resistor R, a proximity illuminance detection sensor 3, and a resistor R2, which are connected in series.
The voltage generated across the resistor R2 is applied to the θ pole, and the voltage generated across the resistor R2 is applied to the θ pole.

It outputs a signal in response to changes in illuminance of both sensors 3 and 4. 13 is also a comparison means B consisting of a comparator,
The voltage generated in the resistor R described above is applied to the e-pole, and the voltage generated in the resistor 12 of the resistors 11 and 12 connected in series is applied to the e-pole. It outputs a signal in response to changes in the sensor 4. The outputs from the one-car comparison means A14.813 are both connected to a control element 5, which will be described later, and the outputs are used to generate sound from a speaker 10, which will be described later. 5 is a control element consisting of a microcomputer, which includes an onomatopoeic data ROM 7 and a voice synthesis LSI 6, which will be described later.
It controls the operation of the 7 is an onomatopoeia data ROM in which digitally processed onomatopoeia data is stored. 6 is a voice synthesis LSI, and the onomatopoeic data ROM 7 is
It has a function of reading the onomatopoeic data extracted from the above, reading it, assembling the synthesized onomatopoeia, performing D/A conversion, and outputting an analog signal. The drive switch 2 is also connected to the control element 5, and both the sensors 3.
When operated separately from the output from the control element 4, an operation signal is inputted to the control element 5 so as to cause an onomatopoeic sound to be produced from a speaker lO, which will be described later. 8 is a filter, and 9 is an amplification element (hereinafter referred to as an amplifier) consisting of an amplifier, and the filter 8 eliminates noise in the high frequency signal contained in the analog signal outputted via the voice synthesis LSI 6, and also, The amplifier 9 amplifies the high frequency signal from which noise has been removed via the filter 8. Reference numeral 10 denotes a speaker, which emits a signal (here, an onomatopoeic sound that camouflages the sound of using the toilet) amplified through a filter 8 and an amplifier 9.

Next, the operation of this embodiment will be described.

When producing the above-mentioned onomatopoeia using a device having such a configuration (description of the case where the drive switch 2 is used is omitted),
First, when the user takes a urinal posture, the user places his hand in front of the proximity illuminance detection sensor 3 to block the light detected by the proximity illuminance detection sensor 3.

The resistance of the proximity illuminance detection sensor 3 increases, and the voltage at point B becomes lower than before placing the hand in front of the proximity illuminance detection sensor 3, and is applied to the e pole of the comparison means A14. At this time, since there is sufficient illuminance around the installation site of the environmental illumination measurement sensor 4, the voltage A at point A applied to the e pole of the comparison means A14 is as follows: Voltage A>Voltage B... ...and comparison means A
The output signal from 14 is input to control element 5.

At this time, the Φ pole of the comparison means B13 has the same potential as the voltage at point A applied to the Φ pole of the comparison means A14, since the area around the installation site of the environmental illuminance measurement sensor 4 has sufficient illuminance as described above. Voltage A is applied to the e pole of comparison means B13,
The voltage C generated at the 0 point is applied to the resistor 12, and under this condition, voltage A>voltage C...
. The output signal from the comparison means B13 is similarly input to the control element 5.

The control element 5 to which the output signals from both the comparison means A14 and B13 are inputted in this way inputs a voice synthesis instruction signal to the voice synthesis LSI 6. The voice synthesis LSI 6, which receives this voice synthesis instruction signal, reads the onomatopoeic data extracted from the onomatopoeia data ROM 7, performs voice synthesis, and outputs an analog signal that has been D/A converted. At this time, the output analog signal is converted from a digital signal and therefore contains a lot of high frequency noise, so the noise is removed through a filter 8.

Further, the signal output is amplified by the amplifier 9, and the amplified signal (an onomatopoeic sound that camouflages the sound of using the toilet) is emitted from the speaker 10.

Now, when the illuminance in the environment at the location where the two-car sensor is installed falls below a certain level, the difference between the voltage A and the voltage B becomes small, and the output signal from the comparison means A14 continues to be input to the control element 5. However, the voltage A applied to the Φ pole of the comparison means B13 and the voltage C applied to the e pole of the comparison means B13 are such that voltage A<It pressure C... In contrast to the above, the output signal from the comparison means B13 is not input to the control element 5.

Therefore, even if the output signal from the comparison means A14 is input to the control element 5, the sound generating device is not driven.

Effects of the Invention According to the present invention, a proximity illuminance detection sensor, an environmental illuminance measurement sensor, a comparison means A that signals a signal according to a change in illuminance of both these sensors, and a signal output according to a change in the environmental illuminance measurement sensor. The apparatus main body is equipped with a sound generating device that operates when there is an output signal from the comparison means B that outputs Since the sensor has a function of detecting the illuminance below a certain level in the environment of the installation site, if the illuminance of the installation environment of one of the two sensors changes to below a certain level, the output of one of the comparison means will be transmitted to the control element. Even in the state where the input is made, the sound generating device will not be driven unless both the comparing means A and B satisfy the AND condition, and it is possible to provide a sound generating device that operates stably and prevents malfunctions due to changes in the environment.
