Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a music box with a striking sound to which a rhythm of striking sounds such as a ticking sound and a tapping sound are added.

[Prior Art] Conventionally, a music box in which a rhythm of hitting sounds such as a ticking sound and a ticking sound is added to the melody played by a music box has a protrusion on the frame as proposed by the present applicant in Utility Model Application No. 67658/1983. A vibrating valve that is formed protrudingly and struck by a drum pin can generate a striking sound, or a plate spring with a base plate whose tip is bent upward as shown in the conventional example in Figure 7 of the same specification. is fixed with rivets and stacked on the diaphragm, and a cam end plate is fixed to the end of the drum, and the unevenness of the cam end plate plays a leaf spring. It was making a banging sound.

In the former case, the position and height of the vibrating valve and the protrusion vary, so there is a drawback that the sound quality and volume of the hitting sound vary, a frame with protrusions is required, and the sound quality of the hitting sound cannot be changed. There are no drawbacks. In addition, in the latter case, it is necessary to press-fit the cam end plate into the drum, making it difficult to synchronize the timing of the music box's sound and the rhythm of the hammering sound.
It is necessary to use a music box with a cam end plate, and the standard type cannot be used, which has the disadvantage of requiring a large number of parts.

[Purpose of the invention] In view of the above-mentioned drawbacks, the present invention allows the use of a standard type music box, reduces the number of parts, reduces costs, and allows the timing of the music box's playing sound and hitting sound to be matched by using a pin on the drum. To propose a music box with striking sounds that does not require any work and can eliminate variations in sound quality and volume of striking sounds.

[Structure of the invention] The present invention is a music box that plays a melody by playing a comb-like vibrating valve with a pin provided on a drum that is rotated by a driving source. The leaf spring is provided with at least one contact portion with the tip of the vibrating valve.

[Example] The present invention will be described below with reference to an illustrated example. The music box with percussion sound is frame 1 in Figures 1 to 3.
The Zenmai 10 in the barrel 2 fixed above is wound by a winding key (not shown) screwed onto the Zenmai shaft 3, and the drum 4 is rotated by this Zenmai drive source with the speed controlled by the wind speed governor 5. be done.

A comb-like diaphragm 6 is fixed on the frame 1 with screws 7, 7, and a leaf spring 8 for hitting sound is stacked on the diaphragm 6 and fixed with one screw 7.

The drum 4 is provided with a large number of pins 9, and the two pins 9a and 9b on the left side in FIG. 2 are for hitting sounds.
Many other pins 9c are composed of melody pins.

Similarly, the diaphragm 6 is connected to the left side 2 as shown in FIG.
The vibrating valves 6a and 6b are for hitting sound, and the other vibrating valves 6
c is configured for melody.

The leaf spring 8 for the above-mentioned hammering sound is attached to the screw 7 as shown in Fig. 3.
A fixing notch 8a that is fixed in place, a positioning bend 8b that corresponds to the side of the diaphragm 6, and a vibration valve 6a.
It is formed by an abutting portion 8c that corresponds to the tip of 6b.

When the drum 4 is rotated by the full drive source, the pin 9c hits the vibration valve 6c of the diaphragm 6, and a music box melody or the like is played. Drum 4 at the same time
The contact portion 8c side of the plate spring 8 is lifted together with the vibration valve 6a by the pin 9a as shown in FIG.
When the vibration valve 6a passes through the vibration valve 6a, the vibration valve 6a and the contact portion 8
c rapidly lowers, and the contact part 8c is connected to the other vibration valve 6b.
A clicking sound is generated.

At this time, the next pin 9 is attached to the vibration valve 6b as shown in FIG.
When b is hit, a hard clicking sound is generated.

Further, when the pin 9b is away from the vibration valve 6b as shown in FIG. 6, a soft clicking sound is generated.

Next, when the pin 9b lifts up the vibration valve 6b and the contact part 8c and passes through it, the vibration valve 6b and the contact part 8c rapidly lower, and the contact part 8c hits the other vibration valve 6a, producing a clicking sound. Similarly to the above, when the pin 9a is in contact with the vibration valve 6a, a hard clicking sound is generated, and when the pin 9a is away from the vibrating valve 6a, a soft clicking sound is generated.

When the music box with percussion is configured as described above, the standard type of music box can be used and it is streamlined, and since the only component is the leaf spring 8, the number of parts can be reduced and costs can be reduced, and the leaf spring 8 is a diaphragm. The assembly work is extremely easy since it is only necessary to stack it on top of the screw 6 and fix it with the screw 7. When the leaf spring 8 has a positioning bending portion 8b that corresponds to the side of the diaphragm 6, positioning and fixing becomes easier.

Furthermore, it is possible to easily obtain hard and soft sound qualities in the hitting sound, and there is little variation in sound quality and volume, making it possible to make them homogenized.

In addition, since the drum 4 only needs to be provided with the melody sounding pin 9c and the striking sound pins 9a and 9b, the melody and the striking rhythm match, and it is possible to reliably prevent timing deviations due to assembly errors, etc., and to adjust the timing. No adjustment is required at all, making assembly work extremely simple and greatly streamlined.

In the above explanation, the number of pins 9a, 9b and vibration valves 6a, 6b for hammering sound are two each, but the number of pins 9a, 9b and vibration valves 6a, 6b other than two may be used depending on the arrangement. One piece is enough. Also pins 9a, 9
b and the vibration valves 6a, 6b may be provided at other positions than the left end.

In the above description, the drum 4 is rotationally driven by a full-length drive source, but it may also be driven by an electric motor.

[Effects of the invention] As mentioned above, this invention is streamlined as it can use the standard type of music box, and since it is only necessary to provide the melody sounding pin and the striking sound pin on the drum, the melody and the striking rhythm match, reducing assembly errors. It reliably prevents the timing from shifting due to other factors, and there is no need to adjust the timing at all, making the assembly work extremely simple and greatly streamlined.The design allows the number and position of the pins for striking sounds to be determined according to the arrangement. When the contact part faces multiple vibrating sound valves, it is easy to obtain hard and soft sound quality, and there is less variation in sound quality and volume, making it possible to make it homogeneous. Therefore, it is possible to provide a music box with hammering sounds that has excellent practical effects such as having a small number of parts and being able to reduce costs.
