You may make it connect with the cord of both ends plug. In the case of the circle merry-go-round type shown in FIG. 2 (A), the input plug 1 has a structure in which the cord 17 can be pulled out from the stand mounting portion 16 by using the dedicated stand 14, or FIG. 2 (B). In the case of the hanging merry-go-round type shown in, the cord 17 is provided so as to be taken out directly from the curved ball portion 6.

The amplifier circuit 2 is for amplifying the audio signal output from the headphone terminal or the like of the external audio output device 9 to the extent that the sounding body 3 can be driven, and is incorporated as necessary. For example,
The amplifier circuit 2 is not required when a speaker system with a built-in booster is used or when a sounding body 3 that can be driven by an audio signal output from a headphone terminal is used.

As the sounding body 3, a small speaker, a piezoelectric speaker, or the like that can be housed in the music ball portion 6 is usually adopted. The rotary drive motor 4 and the amplifier circuit 2 are provided with a power source 12 built in the curved portion 6.
For example, it is driven by a battery, and the power switch 13 opens and closes the circuit.

A motor is usually used as the rotary drive source 4. The rotation of the motor is transmitted to the shaft 8 for suspending the hanging decoration 5 through the reduction mechanism 7. The tip of the shaft 8 has a hook shape so that the hanging ornament 5 can be easily attached and detached.

According to the merry-go-round toy thus configured, it operates by operating as follows.

First, an external audio output device 9 such as a headphone stereo is prepared, and the input plug 1 of the curved portion 6 is connected to the headphone terminal of the external audio output device 9. Then, a cassette tape in which desired music, sounds, etc. are recorded is set in the headphone stereo and played. On the other hand, turn on the power switch of the merry-go-round toy and rotate the merry-go-round. The reproduction signal of the cassette tape is output from the headphone terminal as a voice by driving the speaker 3 via the amplifier circuit 2 of the curved portion 6 and driving the speaker 3. At the same time, the hanging decoration 5 is gently rotated by the drive of the motor 4 of the curved portion 6, attracting the attention of the baby,
Treat your baby and make you sleepy. At this time, it is more effective to hear the sound heard in the mother's womb, the lullaby sung by the mother, and the words to speak.

FIG. 3 shows another embodiment. In this embodiment, an electronic sound generating circuit 10 is provided in the music ball portion 6, and a sound signal to be sent to the amplifier circuit 2 by a changeover switch 11 is sent to an external sound output device 9.
From the electronic sound generating circuit 10 can be selected. The electronic sound generating circuit 10 is known as an electronic music box or the like, and a detailed description thereof will be omitted.

In the case of the embodiment configured as described above, when the headphone stereo or the cassette tape recorder with radio cannot be used, if the changeover switch 11 is set to the electronic sound generating circuit 10 side, the melody stored in advance plays as an electronic music box. It will be.

It should be noted that the above-described embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention. For example,
A mechanical music box may be used as a built-in sound source instead of the electronic sound generating circuit 10 shown in FIG. In this case, the music box may be driven by a motor or a mainspring to directly output the sound, or the vibration of each valve of the music box may be converted into an electric signal by a pickup and the amplification circuit 2 and the speaker 3 described above may be used. You may make it output via.

(Effect of the Invention) As is clear from the above description, the merry-go-round toy of the present invention is provided with a connectable input terminal member and a sounding body for inputting a sound signal from an external sound output device to the music ball portion. Therefore, when the hanging decoration is rotated, the sound input from the external sound output device can be played. Therefore, there is no limitation on the length of the song, and any number of songs can be played. Moreover, not only the music box sound, but also the piano, violin,
It is possible to freely select the type of music or sound without being restricted by the tone color, performance form, music genre, etc. of musical instrument performance such as guitar, singing voice, etc. In particular, the voice of the mother or father can be used to play lullaby or swear words, or the sound of the mother's womb can be heard, so that the baby's sleep and mood are improved.

Further, since the present invention uses a commercially available headphone stereo or a cassette recorder with a radio as an audio signal generation source, it is possible to freely select a sound source or use a tape recorder or the like already in the home. The parts can be made light and inexpensive. Moreover, even if a tape recorder or the like fails,
It is enough to connect to a different sound source or exchange only the sound source,
There is no need to replace the merry-go-round itself. When a built-in electronic sound generation circuit that can be selectively connected by switching is used, an audio signal is input from the electronic sound generation circuit even when an external audio output device such as a headphone stereo is used for other purposes. It can be used as a music box carousel toy.
