Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an onomatopoeic toy that stops producing the imitation sounds of ornamental animals in response to auditory stimulation. Here, the term "animals for viewing" refers to animals such as birds, insects, frogs, etc. that are placed nearby and whose cries are appreciated.

[Background technology] With the advancement of electronics technology in recent years,
TTL (transistor transistor logic)
2. Description of the Related Art Devices are known that use circuits, IC (integrated) circuits, and the like to generate sounds imitating the sounds of ornamental animals.
Such onomatopoeia generators are often used for assembly and craft work by young people to introduce them to electronics technology. The purpose of this onomatopoeic sound generating device is to generate an onomatopoeic sound of an insect, for example, for electric circuit learning.For example, as an onomatopoeic effect of a chirping sound of a sparrow, it oscillates at the fundamental frequency of the insect sound of 4KHz, and oscillates a strength signal. The sound is simply made to resemble the sound of a Suzumushi by using an intermittent timer to emit a sound at regular intervals.

There are also onomatopoeia generators that produce bird calls, but these also only intermittently repeat a sound with a frequency similar to a bird call.

[Purpose of the invention] The present invention is capable of responding to auditory stimuli and giving the impression that an ornamental animal is startled by a loud noise and stops crying, giving the impression that there is a real ornamental animal. The aim is to provide toys that can.

[Structure] In order to achieve the above object, the present invention is structured as follows. That is, an onomatopoeic signal generation circuit that generates a signal for driving a sounding body to generate a sound imitation of at least one kind of ornamental animal, the sounding body, an auditory sensor, and a predetermined signal output from the sensor. The onomatopoeic sound generating toy is characterized by having a timer circuit that turns off the output of the onomatopoeic signal generating circuit.

[Examples] Preferred embodiments of the present invention will be described below based on the drawings.

FIG. 1 is an overview diagram of an embodiment of an onomatopoeic toy that generates an imitation sound of an ornamental animal according to the present invention, and FIG. 2 is a block diagram of an onomatopoeic sound generation circuit and an auditory sensor circuit of this embodiment. It is.

In Figure 1, when switch 1 is turned on, the onomatopoeia generating circuit and auditory sensor circuit are powered on.
A pseudo sound is generated by the piezoelectric speaker 3. When the power is on, the pseudo insect sound continues to play intermittently. The onomatopoeic sound generation circuit 8 shown in Fig. 2 oscillates the fundamental frequency of the sound of a Japanese nestling, for example, 4KHz, modulates it with a strength signal, etc., creates a sound wave pattern of the sound of a natural sound, and an intermittent timer circuit. 7 intermittently generates a signal at regular intervals, and the power amplifier circuit 11
The piezoelectric speaker is made to sound by the piezoelectric speaker. In this state, if there is a loud sound, the microphone 4 detects the sound, the sensor circuit 9 converts the sound into an electrical signal, and the timer circuit 10 is activated. Stop time. This gives the impression that there is a real hornworm that stops chirping when it is startled by loud noises.

Furthermore, in FIG. 1, an insect cage 5 is used and artificial or real flowers and leaves 6 are placed inside the insect cage to enliven the atmosphere.

In this embodiment, there is only one type of insect onomatopoeia generating circuit, but as shown in FIG.
At least two or more types of insect imitation sound generating circuits 8-a and 8-b may be used, or the imitation sounds of multiple types of insects may be generated simultaneously.

Although the present embodiment has been described above with respect to an insect onomatopoeia toy, it goes without saying that similar effects can be obtained with other animals that make sounds, such as frog onomatopoeia toys.

[Effect] As described above, according to the present invention, the production of the pseudo-sound of the ornamental animal is stopped for a predetermined period of time when a loud sound is generated, so it is as if the ornamental animal were startled by a loud noise and stopped crying. It can give an impression, not only as a sound effect to create the environment of the place, but also as if the ornamental animal was actually there.
