Abstract

PURPOSE:To make a weeping doll which changes its weeping sound gradually into a laughing sound when a person talks to it to actuate audio sensing, or when one embraces and fondles for application of vibration, by setting an audio output controller so that the weeping sound emitted through a speaker changes into laughing sound gradually when an audio sensor or a vibration sensor senses the voice/vibration. CONSTITUTION:A voice synthesizing electronic circuit built in a doll comprises a weeping sound synthetic generator 1 which emits waves of baby weeping sound using an audio synthesis integrated circuit, a laughing sound synthetic generating circuit 2, and a sound output controller 6 which controls the audio outputs from these weeping generator 1 and laughing generating circuit 2 in conformity to the information given by an audio sensor 3 and a vibration sensor 4 and actuates a speaker 5 to emit a weeping or laughing sound. If accesses cause a large frequency of vibration sensings and the cumulated count on a counter (d) has become plus, the weeping sound is stopped, and the laughing waveform of the laughing generating circuit is amplified, and the speaker 5 is actuated to emit laughing, when the volume is varied at three stages in accordance with the value of counting. Thereby the weeping becomes louder gradually when the doll is left untouched, and if fondled, on the contrary, the weeping becomes lower gradually to then be turned into laughing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a toy doll incorporating a voice synthesis electronic circuit and capable of making cries and laughs.

[Prior Art] So-called talking dolls in which a voice synthesis electronic circuit is built into the doll body have been known for some time. Conventional talking dolls tend to be unattractive because they often randomly utter several types of words that are pre-stored on a record or a voice synthesizer.

[Purpose of the Invention] Therefore, the present invention has been developed to develop a pimple that makes a crying sound by leaving it alone, and also makes the crying gradually change into a laughing sound by talking to it and sensing the sound, or by holding it and giving it vibrations. The idea is to provide dolls.

[Means for Achieving the Object] In order to achieve the above object, the Nakimushi doll of the present invention is equipped with a crying synthesis generator, a laughing synthesis generator, a voice output controller, a speaker, a voice detection sensor, and a vibration detection sensor. A voice synthesis electronic circuit is provided inside the doll body, and the voice output controller is set so that the crying voice emitted by the speaker gradually changes to a laughing voice as the voice detection sensor or vibration detection sensor detects the voice or vibration. It is something.

[Example] Next, an example of the rattle doll of the present invention will be described with reference to the drawings.

As shown in Figure 1, the voice synthesis electronic circuit built into this doll includes a cry synthesis generator 1 that generates the waveform of a baby's cry using a voice synthesis integrated circuit, and a voice synthesis generator 1 that generates the waveform of a baby's laughing voice. a laughter synthesis generation circuit 2 generated by an integrated circuit;
The voice output controller 6 controls the voice outputs of the cry synthesis generator 1 and the laughter synthesis generation circuit 2 according to information from the voice detection sensor 3 and the vibration detection sensor 4, and causes the speaker 5 to emit a cry or laughter. The audio sensor 3 uses a microphone that can detect the surrounding sound pressure level. In addition, the vibration detection sensor 4 is equipped with a conductive ball that can freely swing in a hemispherical chamber with an electrical contact inside, and the electrical contact opens and closes according to the amount of swing, thereby suppressing the vibration. We are using something that can be detected.

A plastic box 7 incorporating this voice synthesis electronic circuit is embedded in the back of the doll body 8 as shown in FIG. Reference numeral 9 indicates a battery for its operation, and 10 indicates a switch.

A flow chart of the operation of the voice output controller 6 is shown in FIG. First, when the switch 10 is turned on, the timer in step a causes 5 seconds to elapse after the switch is turned on. Then, in step b, the audio output controller 6 causes the speaker 5 to output the crying waveform from the crying synthesis generator 1 at a medium volume.

Then, in step C, the presence or absence of input from the voice sensing sensor 3 and the vibration sensing sensor 4 is detected, and the voice input (8
If there is no voice input (more than 5 db) or vibration detected, minus one is added to the counter d, and if there is voice input (more than 85 clb) or vibration detected, plus one is added to the counter d. Therefore, the counter d has a voice detection sensor 3. The counted value is added or subtracted depending on whether the vibration sensor 4 detects sound or vibration or not. Note that the detection interval (access time) is set to about 3 seconds, which is the same as the crying generation cycle. Then, the counter d changes the crying volume to three levels (high, medium, and low) according to the counted value, and when the number of times of sound or vibration is increased due to access and the cumulative counted value of the counter d becomes positive, the crying is stopped. The laughter waveform of the laughter synthesis generating circuit 2 is amplified and the laughter is emitted from the speaker 5, the volume of which is changed into three levels of large, medium and small according to the counted value. In this way, if the doll is left alone, its cries will gradually become louder, and if it is cradled, its cries will gradually become quieter and turn into laughter, and if it continues, the laughter will gradually become louder. The timer in step e detects the time when the count value of the naori counter d is negative (that is, the time when the baby cries), and the power is automatically turned off after about 30 seconds. In other words, if you continue crying for about 30 seconds, it will automatically stop.

In the Nakibug doll configured in this way, switch 10
If you put it in and leave it alone, it will continue to cry, and if you talk to it, pat it on the back, or shake it, the voice detection sensor 3. When sound or vibration is detected by the vibration sensor 4, the count value of the counter d increases and the cry gradually becomes smaller and turns into laughter, reacting as if it were a living human baby. Even if she is laughing, if she is left unattended again, the value on the counter d will decrease and she will start crying again.

[Effects of the Invention] As described above, the Nakibug doll of the present invention changes its crying into laughter by sensing sound or vibration, so it has a novel feature that reacts as if it were alive. It is something.
