Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a sound generating device capable of detecting light, heat, sound, etc. and generating sounds, music, etc. with preset contents.

[Conventional technology]

As a conventional sound generating device, for example, there is an electronic music box, and by opening the lid of a small box equipped with an electronic circuit or turning on a switch provided on the outer surface,
There is a device in which the electronic circuit operates and a melody or the like is generated from a speaker connected to the circuit.

By using electronic circuits in this manner, it is possible to achieve miniaturization and a longer life, and it is also possible to eliminate the need for manual winding.

[Problem that the invention seeks to solve]

However, with conventional sound generators, it is necessary to turn on the switch manually to operate the electronic circuit.
It is unsuitable for applications that impress people, and it is desired to develop a device that can operate automatically in response to some change in the external environment.

[Means for solving problems]

The present invention has been made in view of the above, and includes sensor means for detecting intentionally applied light, heat, sound, etc., in order to enable an electronic circuit for generating sound to be started without manual operation. Accordingly, there is provided a sound generating device which generates a preset melody-1 sound and the like.

〔Example〕

Hereinafter, the sound generating device according to the present invention will be explained in detail.

FIG. 1 shows a sound generating device according to an embodiment of the present invention, which includes a sensor section 1 that makes the resistance between the output terminals low when the level of light, heat, sound, etc. is exceeded, and the output terminal of the sensor section 1. an integrated circuit 2 that outputs an audio signal according to a preset melody-1 voice, etc. when the resistance changes between the two, and a battery 3 that provides power to the voice generator;
A resistor 4 that is connected in series with the output terminal of the sensor section 1 and applies the voltage generated between the terminals to the D terminal of the integrated circuit 2, a transistor 5 that amplifies the power of the output signal of the integrated circuit 2, and a collector voltage of the transistor 5. It is comprised of a speaker 6 connected between the ponds 3 and emitting a predetermined melody or voice.

The sensor section 1 uses a phototransistor 11 to connect between the output terminals when operating by detecting light, and uses a thermistor instead of the phototransistor 11 when operating by detecting heat. Furthermore, when operating by detecting sounds such as applause, for example, a sensor section l having the configuration shown in FIG. 2 is used.

That is, the sensor section 1 for sound detection includes a microphone 12, an amplifier 13 that amplifies the output signal of the microphone 12 to a predetermined level, and a "1" level when the output signal of the amplifier 13 exceeds the level. A Schmitt circuit 14 that outputs an output signal, a transistor 15 that becomes conductive when the output of the circuit 14 is at the "1" level, and a resistor 16 connected between the emitter of the transistor 15 and the resistor 4. be done.

In the configuration shown in FIG. 2, the audio signal captured by the microphone 12 is amplified by the amplifier 13, and is then amplified by the Schmitt circuit 14.
is applied to The Schmitt circuit 14 sets the output level to "0" for signals higher than the level of applause, whistles, etc.
When the output of the Schmitt circuit 14 is inverted to the "L" level, the transistor 15 becomes conductive and generates a voltage across the resistor 4. The voltage generated across this resistor 4 is set to a value that allows the integrated circuit 2 to operate.

Now, returning to FIG. 1, a case will be described in which the phototransistor 11 is used as a sensor for the operation of the sound generation circuit.

The integrated circuit 2 shown in FIG. 1 supplies a power supply with a positive potential to the A terminal, a power supply with a negative potential to the B terminal, and uses the power supply 3 as a reference voltage to the D terminal, and when a voltage higher than the reference voltage is applied, A melody output is induced at the C terminal, and when a voltage lower than the reference voltage is applied, no melody output is induced at the C terminal. When a melody output appears at the C terminal, a base bias voltage is supplied to the transistor 5, and the melody stored in the integrated circuit 2 is played from the speaker 6.

In order to apply a voltage higher than the reference voltage to the terminal of the integrated circuit 2, when light is applied to the phototransistor 11 in the sensor section l, the internal resistance decreases and the voltage dividing point (hot end side of the resistor 4) is ) may be configured so that the voltage increases. When the amount of light applied to the phototransistor 11 becomes less than a certain value, the internal resistance of the phototransistor 11 increases, the voltage across the resistor 40 becomes less than the reference voltage, and the integrated circuit 2 stops operating.

FIG. 3 shows an example in which the sound generating device having the configuration shown in FIG. 1 is applied to mouth-socks for celebrations such as birthdays, weddings, and Christmas.

The candle 30 has a main body 3 made of paraffin in a cylindrical shape.
1 and an interlining 32 disposed at the center of the main body 31. Furthermore, a space is formed at the bottom of the candle 30 to accommodate a bottom surface 33 that accommodates each component of the structure shown in FIG. An optical fiber 34 is provided close to the interlining 32, and the lower end thereof is connected to the phototransistor 1.
It is arranged so as to face the light receiving surface of No. 1.

In the above configuration, when the tip of the interlining 32 is ignited, the light is transmitted to the phototransistor 11 via the optical fiber 34.
The light is received by the The internal resistance of the phototransistor 11 is reduced by light detection, increasing the current flowing through the resistor 4,
A voltage exceeding the reference voltage is generated across the resistor 4. As a result, the integrated circuit 2 operates as described above, and a melody is output.

In addition to melodies, the content to be output can be anything such as human voices synthesized by voice, animal sounds, teaching materials such as religious texts, sermons, and foreign language practice texts. These are individually stored in the integrated circuit 2, and by replacing them, it is possible to enjoy the desired audio content.

In addition, although we have shown an example of a candle as an applicable product, it can be set inside a book and activated by detecting the outside light when the door is opened, or it can be set in the bedroom and activated by detecting the outside light when the door is opened. It is also conceivable that the system could be operated to herald the coming of a new era.

Furthermore, for religious applications, a light-receiving element may be disposed in front of the Buddha statue, and a sutra message may be generated upon irradiation with a spotlight.

In addition, it is possible to install it in a car and guide the light from the backlight to a light receiving element through an optical fiber, and generate a sound such as "Don't back up. Please move out."

Next, a case where a heat-sensitive element such as a thermistor is used in the sensor section 1 will be described. An example of an applicable product in this case is an ashtray.

A sound generating device can be constructed by storing components other than the sensor section 1 in the bottom of the ashtray and arranging the heat-sensitive element at a position where a cigarette is rubbed out.

In the above configuration, when a lit cigarette is pressed against the ashtray or a lit cigarette is left unattended, the heat is transmitted to the heat-sensitive element, reducing the internal resistance of the heat-sensitive element. As a result, the voltage across the terminals of the resistor 4 exceeds the reference voltage, causing the integrated circuit 2 to operate and outputting the memorized melody or other sound. This not only warns people if they forget to put out their cigarettes, but also encourages people to extinguish their cigarettes, as some people put out their cigarettes to play the melody.

Next, a case will be described in which a sound detection circuit as shown in FIG. 2 is used in the sensor section l. Examples of applicable products in this case include "omikuji" vending machines placed at shrines and the like. A microphone 12 is disposed in front of it, and other parts are disposed inside the "fortune" vending machine or the like.

In the above configuration, when you clap in front of the "Omikuji" vending machine, the clapping sound is detected by the microphone 12, and if the sound is above the level, the transistor 15 becomes conductive, and the resistor 4 has a voltage higher than the reference voltage. Generate voltage. As a result, the integrated circuit 2 is activated and outputs the stored music such as gagaku. In this case, the activation of the integrated circuit 2 may be based on the insertion of a coin;
The "fortune" dispensing mechanism may be operated in conjunction with the activation of the "fortune".

In addition, products that use a sound detection circuit in the sensor unit 1 include those that detect the crying of an infant and generate a melody, and those that install the sensor unit 1 away from a TV or stereo to make a sound. When the pressure energy exceeds the value
Please reduce the sound. ” etc. can be considered.

〔Effect of the invention〕

As explained above, according to the present invention, a sound such as a melody word is generated when light, sound, heat, etc. are applied, so the sound generation is ideal for application to gifts and idea products. You can get the equipment.
