DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a music box device according to the present invention will be described below with reference to the drawings.

First Embodiment FIGS. 1 and 2 are explanatory views showing an embodiment in which the present invention is applied to a disc music box device.
Is a plan view, and FIG. 2 is a sectional view. 1 and 2
As shown in FIG. 1, the disc music box device 1 includes a rotating shaft 12 for holding and rotating the disc D, a driving unit 13 for rotating the rotating shaft 12 at a constant speed, and a symmetrical position on the housing 30 with respect to the rotating shaft 12. The holding plates 4 and 14 fixed to the holding plates 4, the scale plates 10 and 20 having comb teeth formed in a predetermined number of flat plates corresponding to the number of scales provided on the holding plates 4 and 14, respectively, and the holding plate 4 , 14 are rotatably held by support shafts 8, 18 respectively provided on the outer circumference thereof, and are provided with claws 6a, 16a on the outer periphery thereof.
And housings 31 and 30 provided at the bottom of the housing 30 to correspond to the two holding plates 4 and 14, respectively.
Vibrating plates 24, 28 provided at the bottom of housings 31, 30
And transmission members 22 and 26 for connecting the housings 31 and 30 and the diaphragms 24 and 28, respectively.

The disc D is made of, for example, an aluminum disk and has an engaging portion (not shown) for engaging with the claws 6a, 16a of the star wheels 6, 16. The engaging portion is composed of, for example, a plurality of protrusions formed intermittently in the circumferential direction for each track from the inner circumference to the outer circumference of the disk D. The protrusions project part of the disk D and protrude from the surface of the disk D. The protrusions engage with the claws 6a, 16a of the star wheels 6, 16 to rotate the star wheels 6, 16. .

The drive section 13 is composed of, for example, a motor, a gear train, and the like.
2 is rotated at a predetermined speed.

The scale plates 10 and 20 may have exactly the same scale, or may have a full scale and one chromatic scale, and may have a chromatic scale. Select the scale to be used.

The holding plates 4 and 14 are independently formed of, for example, cast members, and directly hold the scale plates 10 and 20, respectively. Therefore, the sounds emitted from the scale plates 10 and 20 are transmitted to the holding plates 4 and 14, respectively, and do not interfere with each other.

The star wheels 6, 16 can be formed, for example, from a metal material. In addition, a plurality of claws 6
a, 16a are formed, and the claws 6a, 16a are engaged with the engaging portions formed on the rotating disk D, whereby the star wheels 6, 16 themselves rotate, respectively, and the rotated star wheel 6 is rotated. , 16 claws 6a, 16
a plays the comb teeth of the scale plates 10 and 20. Thereby, a sound of a predetermined scale is generated.

The housings 31, 30 can be formed from, for example, a wooden plate. Alternatively, a relatively soft and low-rigidity material can be used to form the housings 31 and 30.

The transmission members 22, 26 can be formed of a relatively light material such as a wooden pillar.
The fixed positions of the transmission members 22 and 26 are provided below the holding plates 4 and 14 via the housings 31 and 30, respectively.
It plays a role of transmitting sounds from the scale plates 10 and 20 to the diaphragms 24 and 28, respectively.

The diaphragms 24 and 28 are respectively provided with a housing 31 and a housing 31.
The transmission members 22, 26 are provided at the bottom of the base 30 and are fixed by, for example, an adhesive. The diaphragms 24 and 28 play a role in increasing the sound transmitted through the transmission members 22 and 26. In other words, the sounds emitted from the scale plates 10 and 20 are not metallic and are not preferable timbres, but become excellent and preferable by being amplified by the diaphragms 24 and 28.

In the disk music box device 1 configured as described above, when the drive unit 13 rotates the rotating shaft 12 at a predetermined speed, the disk D rotates. When the disk D rotates, a plurality of protrusions formed intermittently in the circumferential direction for each track from the inner circumference to the outer circumference of the disk D engage with the claws 6a, 16a of the star wheels 6, 16, respectively. The wheels 6, 16 rotate. When the claws 6a and 16a of the rotating star wheels 6 and 16 hit the comb teeth of the scale plates 10 and 20, respectively, a predetermined melody is played.

At this time, for example, a melody of a predetermined music piece on the musical scale plate 10 and an accompaniment on the musical scale plate 20,
When the plurality of projections of the disk D are arranged so that the performance parts of the scale plates 10 and 20 are different, multiple performances are performed by the disk music box device 1. In the case of multiple performances by the disc music box device 1, for example, even when sounds are simultaneously emitted from the scale plate 10 and the scale plate 20, the sounds from the scale plate 10 and the scale plate 20 interfere with each other. Never. That is, the holding plates 4 and 14 and the housing 3
Since the diaphragms 1 and 30 and the diaphragms 24 and 28 are provided independently of each other, the tone from the disc music box device 1 is not distorted, and a desired tone can be obtained.

Further, according to the disk music box device 1 of the present embodiment, multiple performances can be performed on one disk D. That is, since each musical scale plate 10 and 20 is played by rotating one disk D, each part can be reliably synchronized, and excellent performance can be performed.

Further, the disc music box device 1 according to the present embodiment has independent holding plates 4 and 14, casings 31 and 30, and diaphragms 24 and 2 which do not interfere with each other's sounds.
Because of the structure having eight, the sound emitted from the disc music box device 1 can be made three-dimensional when performing multiple performances.

Second Embodiment FIG. 3 is an explanatory view showing another embodiment of a music box device according to the present invention. The music box device 41 shown in FIG.
The plurality of projections 55a formed on the rotating drum 55 play the two scale plates 51 and 53, and can play a predetermined melody. Scale board 51,
53 are held by separate holding plates 52 and 54, respectively.
6, 57. As in the case of the first embodiment, the housings 56 and 57 are provided with a transmission member and a diaphragm.

With the above configuration, the first
As in the case of the embodiment, when multiple performances are performed by the two scale plates 51 and 53, the tone from the music box device 41 is not distorted, and a desired tone can be obtained. Further, since each musical scale plate 51, 53 is played by rotating one rotary drum 55, the performance parts of the musical scale plates 51, 53 can be reliably synchronized, and excellent performance can be achieved. . Further, by performing multiple performances, the sound emitted from the disc music box device 41 can be made three-dimensional.

[0023]

As described above, according to the music box device of the present invention, in the case of multiple performances, for example, even when sounds are simultaneously emitted from each scale plate,
Since the sounds from the respective scale plates do not interfere with each other, and since the respective holders and the respective vibrator plates are provided independently of each other, the tone from the music box device is not distorted, and a desired sound is obtained. A tone will be obtained.

Further, according to the music box apparatus of the present invention, multiple performances can be performed by one rotating body, and each musical scale plate is played by rotating one rotating body. Synchronization of the performance parts of the board can be reliably performed, and excellent performance can be achieved.

Further, according to the music box device of the present invention, since the sounds emitted from the respective musical scales do not interfere with each other, the sound is emitted from the music box device when performing multiple performances. Sound can be three-dimensional.
