Description

[Detailed description of the invention] This invention relates to toys that are activated by sound, and in particular, the switching action of starting and stopping a toy that makes noise, such as a monkey hitting a cymbal, can be controlled by a specific number of sounds that are received by a microphone. To provide a sound-activated toy that is configured to perform operations based on a signal generated using sound as an input, can move in response to a person's voice, applause, or the sound made by the toy itself, and allows fun play. The purpose is to

Hereinafter, embodiments of this invention will be described based on the drawings. FIG. 1 shows a block diagram of a toy operated by sound, and FIG. 2 shows a toy monkey that incorporates the device shown in FIG. 1 and plays cymbals. 1 is a microphone installed in the front of the monkey doll 2, and 3 is an amplifier connected to the microphone 1. 4 is a control amplifier connected to the output side of the amplifier 3; a one-shot multivibrator that outputs one pulse signal when two signals of a certain level are input from the amplifier 3 within a certain time; It consists of a flip-flop circuit that receives a pulse signal from a one-shot multi-valve generator and operates a switch circuit. Reference numeral 6 denotes a driving motor for driving the monkey doll 2 to hit the cymbal, and is connected to the switch circuit 5. Note that the flip-flop circuit is attached with a time constant circuit that is reset with a certain delay time when a reset signal is input thereto.

A cymbal-beating monkey doll incorporating such a device operates as follows.

When a person clap their hands or make a sound toward the monkey doll 2, and two sounds are applied to the microphone 1 within a certain period of time, two signals at a certain level are sent to the control amplifier via the amplifier 3. The signal is input to No. 4 one-shot multi-valve regulator within a certain period of time.
Then, 1 from the one-shot multi-valve regulator
A pulse signal is applied to the flip-flop circuit to set this circuit, and a signal is sent to the switch circuit 5 to turn on the switch. Then, the motor 6 is started, and the monkey doll 2 performs the action of hitting the cymbal.

When two cymbal sounds from the monkey doll 2 are input to the microphone 1 within a certain period of time, one pulse signal is applied from the one-shot multivalve generator of the control amplifier 4 to the flip-flop circuit in the same way as above. , the circuit is reset after a certain delay time. Therefore, switch circuit 5
After the monkey doll 2 hits the cymbal twice, it is turned off after a certain period of time, the motor 6 stops, and the movement of the monkey doll 2 stops.

In this way, it can be started in response to sounds made by a person at regular intervals, and can be stopped by a certain number of sounds made by the doll itself, making the doll move as if imitating a person. Can be done.

As described above, according to the sound-activated toy of this invention, it is configured to start in response to the sounds made by a person at regular intervals, and to stop after a delay time due to the sounds generated by the toy itself. Toys can make sounds by imitating sounds made at regular intervals such as people's voices and applause, and children can enjoy playing by watching the toys move in response to people's voices and applause.
