Description

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

[Prior art]

Conventionally, a music box that adds the rhythm of hitting sounds such as ticking and ticking sounds to the melody played by a music box is made to vibrate by fixing a base plate 17 whose tip is bent upward and a leaf spring 18 with a rivet 19 as shown in Fig. 7. The cam end plate 20 is fixed to the end of the drum 6, and the unevenness of the cam end plate 20 allows the spring plate 1 to be fixed on top of the plate 8.
8, and when the spring plate is flipped, it hits the bent end of the main plate 17 and generates a hitting sound. In another structure, the shaft of the drum 6 is made to protrude from the frame 3, the cam end plate is fixed, and the spring plate is exposed.

In the above structure, due to the assembly error between the drum and the cam end plate, a timing difference occurs between the melody and the hitting sound when the drum pin plays the vibration valve, and the disadvantage is that it is difficult to suppress the variation in timing difference, and there are many parts. .

[Purpose of invention]

In view of the above-mentioned drawbacks, the present invention provides a music box with percussion sounds that uses a vibrating valve that is played by a drum pin to generate percussion sounds such as ticks and taps with a simple structure.

[Structure of the idea]

The present invention provides a music box in which a pin provided on a drum rotated by a driving source plays a vibrating valve to play a melody, etc., in which at least one vibrating valve is placed below.
A sounding body having a sounding collision part facing the vibration range of the vibration valve is provided.

〔Example〕

The present invention will be explained below with reference to illustrated embodiments. The music box with percussion sound is lower case 1 in Figures 1 to 3.
The frame 3 of the music box 2 is fixed with screws 10, and the Zenmai inside the barrel 4 fixed on the frame 3 is wound up by the Zenmai shaft 5, and the drum 6 is driven by the wind governor 7 by this Zenmai drive source. It is rotated at controlled speed.
When the full-length shaft 5 is wound up, it is done by pulling out a string 12 wound around a pulley 11 screwed onto the lower end of the full-length shaft.

A diaphragm 8 is further fixed on the frame 3, and valves 8a, 8a at each end of the diaphragm 8 are positioned against flanges 13, 14 fixed on both sides of the drum 6.

As for the pins of the drum 6 in FIG. 1, the three pins 6a in the A range on the left are for hitting sounds, and the other pins 6b in the B range are for melody pins.

Similarly, in FIG. 1, the three vibrating valves 8b on the left side of the diaphragm 8, that is, the second to fourth vibrating valves 8b, are for percussion, and the case 1 below the vibrating valves 8b has a sounding body 1a. The sounding collision portion at the tip of the sounding body 1a is exposed to the vibration range of the vibration valve 8b. The vibration valve 8c in the B range of the diaphragm 8 is configured for melody.

The relationship between the pin 6a for playing the vibrating valve 8b and the pin 6b for playing the vibrating valve 8c is such that the vibrating valve 8b is played in accordance with or in sync with the melody.

When the drum 6 is rotated by the full drive source, B
Vibration valve 8c in range B of diaphragm 8 with range pin 6b
is played, and the melody of music box 2 is played. At the same time, when the vibration valve 8b in the A range of the diaphragm 8 is flipped by the pin 6a in the A range of the drum 6, the vibration valve 8b
Since the sound-producing collision part of the sounding body 1a is provided in the vibration region of , the vibration valve 8b lifted by the pin 6a as shown by the solid line in FIG.
A is hit and a hitting sound is generated.

When a music box with a striking sound is constructed as described above, the striking pin 6a of the drum 6 is formed integrally with the melody pin 6b, so the melody and rhythm match, and the timing will not deviate due to assembly errors etc. is reliably prevented, and the number of parts is reduced to 1a.
Since the sounding body 1a only needs to be formed integrally with the case 1, there is no need to adjust the timing at all, making assembly extremely simple and greatly streamlined.

In the above description, the number of pins 6a and the number of vibration valves 8b for tapping sounds are three each, but the number of pins 6a and number of vibration valves 8b other than three may be used, or may be one, depending on the arrangement. Further, the pin 6a and the vibration valve 8b may be provided at other positions than the left end.

FIG. 5 shows a modification in which a sounding body 3a is integrally provided on the frame 3 of the music box 2, but the sounding body 3a may be separately fixed to the frame 3 with screws or caulking.

By using a different material such as glass as the material of the sounding body, it is possible to create a tone different from that of synthetic resin or metal.

The position of the sounding body that contacts the vibration valve may be lowered so that the vibration valve contacts the sounding body and then vibrates.

Products may be developed by combining the above-mentioned different tones, the timing of the vibration when the vibration valve hits the sounding body, the vibration contact sound, and the strength of the sound.

FIG. 6 shows an application example in which a hook portion 15 is fixed to the diaphragm 8 and a string 16 is plucked by the hook portion.

In the timing explanation, the drum 6 is rotationally driven by a full-length drive source, but it may be driven by an electric motor.

[Effect of idea]

As mentioned above, this invention uses a vibrating valve to generate striking sounds, which simplifies the structure and greatly streamlines it, making it extremely easy to synchronize the melody and rhythm, eliminating the need for adjustment at all, and making it easier to arrange. In addition, the number and position of the hammering pins are determined, increasing the degree of freedom in design, and providing a music box with hammering sounds that has excellent practical effects, such as widening the range of product development.
