Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a music box, and particularly to one that allows a musical instrument to be played simultaneously with the reed performance.

[Conventional technology]

A music box has a large number of pins protruding from the rotating peripheral surface of a drum, and a reed that is placed opposite to the pins and is played by the pins to produce a tone.

[The problem that the invention is trying to solve]

However, since a music box can only emit as many tones as the number of reeds, the performance is relatively simple and easy to get boring.

In order to solve this problem, this invention aims to make it possible to perform music boxes with more variety by adding musical instruments in addition to reed performances.

[Means for solving problems]

This idea involves attaching a musical instrument and an actuator that drives the instrument to a music box that has a drum with many pins protruding from its rotating surface and a reed that produces sound when one end is played by the pins. A music box in which movable contacts having elasticity are disposed at positions facing each other and one end contacts these pins, a fixed contact is disposed within the movable range of the movable contact, and these movable contacts and the fixed contact constitute an operating switch of the actuator. is proposed to solve the above problems.

[Effect]

When the drum starts rotating, the pin starts playing by playing the reed. On the other hand, this pin also contacts the movable contact and moves it, and the movable contact contacts the fixed contact to operate the actuator, thereby playing the musical instrument.

In other words, in this music box, musical instruments are played in parallel with the reed performance, resulting in a richly flavored performance.

〔Example〕

FIG. 1 is a systematic perspective view showing the main parts of an embodiment of this invention.

In the figure, 1 is a drum, 2 is a pin, and 3 is a reed. The drum 1 is connected to a drive source (for example, a constant torque spring motor), also not shown, in a music box machine frame (not shown) through its shaft 7. and erect it. Further, the pins 2 are arranged and protruded from the rotating circumferential surface of the drum 1 in accordance with the music to be played.

Further, 6 is a percussion instrument imitating a cymbal, and the actuator 5 is actuated to make this percussion instrument 6 sound. Of course, the present invention is not limited to such percussion instruments, and it is also possible to use other types of musical instruments, such as wind instruments such as a ratuppa, or stringed instruments such as a guitar.

The reeds, indicated as a whole by 3, are also constructed and fixed in the music box machine frame via a stand 8 so that their tips are hooked onto these pins 2.

In this embodiment, a part of the lead 3 also serves as a movable contact, and this part becomes the music signal piece 4. That is, this music signal piece 4 is fixedly installed on the stand 8 together with other leads 3, and is arranged so that its tip is hooked on the pin 2.

Although three music signal pieces 4 are selected in the illustrated embodiment, the number is not limited, of course.

Furthermore, movable contacts 9 are arranged directly below each tip of the music signal piece 4 at positions facing each other. The base end of the music signal piece 4 fixed to the stand 8 and the fixed contact 9 are respectively connected to an actuator 5 which is a solenoid.
These music signal pieces 4 and fixed contacts 9 constitute an operating switch of the actuator 5.

That is, as shown in FIG. 2, when the drum 1 rotates as shown by the arrow, the pin 2 flicks the tip of the music signal piece 4, which vibrates as shown by the imaginary line in FIG. It is now connected to the When the music signal piece 4 and the fixed contact 9 are connected in this way, the operating switch of the actuator 5 is closed, and the musical instrument 6 is played by operating this switch.

Note that the power source for operating the actuator 5 is
It is located within the casing of the actuator 5 and is not shown.

As described above, with the music box of this embodiment, it is possible to play the musical instrument 6 in synchronization with the performance by the reed 3, and it is possible to enjoy the taste of the combination of both performances.

In this embodiment, the reed 3 has a structure that also serves as the music signal piece 4, that is, the movable contact, but both may be provided separately. may be provided.

〔effect〕

According to this invention, since the movable contacts are played with pins to cause the musical instrument to perform music, it is possible to perform musical instruments other than the music box in parallel with the playing of the music box, making it possible to create an interesting music box. can do.
