Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a music box with a switch that is switched by a driven member that pushes up the switch by a vibration valve that is played by a switch pin on a drum.

[Prior art]

Previously, as in Japanese Utility Model Application Publication No. 55-35570, a music box was proposed in which a vibrating valve and a protruding pin on a drum were used to double as a switch, and the switch was turned on for a short time before the vibrating valve and the pin came into contact and the sound was produced. However, in this switch mechanism, the vibration valves are insulated one by one, and each vibration valve functions as an independent switch, so it has the advantage of being able to synchronize the lighting for each sound. However, each independent and special vibration valve is fixed, which has the drawback of lacking practicality, especially mass production.

If you use a vibration plate that is made up of multiple vibration valves integrated with an emphasis on practicality, most of the vibration valves will be in contact with the pin during most of the rotation of the drum, so there will be no light emitted in the switch circuit. Even if a light emitting device such as a diode or a light bulb is connected, it has the same drawbacks as the conventional example above, that it lights up momentarily before the sound is produced, but does not light up long enough to know that it has been lit, and does not blink in time with the song. .

[Purpose of invention]

In view of the above-mentioned drawbacks, the present invention enables a music box that uses a normal integrated vibration valve to turn on and off in accordance with the music, and also enables the generation of sound at the same time as when blinking light-emitting objects such as light-emitting diodes and light bulbs. The purpose is to propose a music box with a switch that can turn on the light emitter.

[Structure of the idea]

This invention is a music box in which a protruding pin on the drum plays a vibrating valve to make a sound, and a part of the protruding pin on the drum is used as a switch pin and is fixed on the vibrating valve that is played by the switch pin. Press the switch by applying the driven member that allows the contact piece and the movable contact piece to move toward and away from each other.
It is equipped with a switch that is turned on, turned off when the driven member is pushed up by the vibration valve, and returned to its original state when lowered.

〔Example〕

Hereinafter, the present invention will be explained with reference to an illustrated embodiment. In the music box with a switch, as shown in Figs. 1 and 2, the entire barrel 11 in the barrel 11 fixed on the frame 10 of the music box 1 is wound up by the main shaft 2, and the drum 3 is driven by the wind speed governor by this main drive source. 12 and rotates.

A diaphragm 4 is further mounted on the frame 10 with screws 1.
3 and 14, and one valve 4a, 4a at each end of the diaphragm 4 is positioned against flanges 15, 16 fixed on both sides of the drum 3.

Generally, in a music box, the protruding pins on the arrangement drum 3 and the vibration valves on the diaphragm 4 are arranged separately for a melody section and an accompaniment section.

In Fig. 1, the three rows of protruding pins 3a, 3b, and 3c of the drum 3 in the accompaniment section on the left are for switches, and the other many protruding pins 3d are for the melody section. .

Similarly, in Figure 1, from the second to the left side of the diaphragm 4,
The three vibrating valves 4b to 4d are for turning on and off switches, and the other numerous vibrating valves 4e on the vibrating plate 4
is composed for melody. Vibration valve 4b~
A driven member 5 made of a leaf spring is fixed to the upper side of 4d with screws 13.

As shown in FIG. 2, the driven member 5 has a bent portion 5a whose tip is bent downward, and has three vibrating valves 4b to 4d.
It is superimposed on top of. Furthermore, the driven member 5 is formed with an upwardly rising portion and a bent portion 5b, and the bent portion 5b is made to freely approach and separate from the printed pattern 6a of the circuit board 6 fixed on the barrel barrel 11. is configured.

A plurality of printed patterns 6b are formed on the circuit board 6.
~6f is formed. print pattern 6c
6f is concentric with the full axis 2 and is formed of an arcuate sliding contact portion and a terminal portion. A rotary contact piece 8 is fixed to the entire shaft 2, and the rotary contact piece 8 is in sliding contact with the printed patterns 6c to 6f to constitute a changeover switch.

A battery 9 is connected to the printed patterns 6a and 6b. Print patterns 6b and 6c to 6f
A plurality of light-emitting bodies 17, 18, 19, and 20, such as light-emitting diodes and light bulbs, are connected between the terminal portions of the terminals.

The driven member 5 and printed patterns 6a, 6
The electric circuit of the elements b, 6c to 6f, the light emitters 17 to 20, and the battery 9 is as follows.

Driven member 5 → Print pattern 6a → Battery 9 →
Print pattern 6b → each light emitting body 17, 18, 1
9, 20→each printed pattern 6c to 6f→rotating contact piece 8→all moving axes 2→frame 10→driven member 5, and when the bent part 5b is in contact with the printed pattern 6a, the rotating contact piece in FIG. The light emitters 17, 19 connected to the printed patterns 6c, 6e in contact with the strip 8 are illuminated.

The operation of the above-mentioned music box with a switch is as follows: When the full-length drive shaft 2 and the drum 3 are rotated, each vibration valve 4e in the melody section of the diaphragm 4 is played by a plurality of protruding pins 3d, and the music box 1 is activated. A melody, etc. is played. At the same time, switch pin 3 of drum 3
When the on/off vibration valves 4b to 4d of the diaphragm 4 are bent and pushed up by any one of a, 3b, and 3c as shown in the operation pattern diagram in FIG. 3, the driven member 5 is bent in the same way. When the bent portion 5b is separated from the printed pattern 6a, the music synchronization switch 7 is turned off and the light emitters 17 and 19 are turned off as shown in FIG. When the switch pin is removed from the vibrating valve that has pushed up the driven member 5, the vibrating valve is flipped and vibrates, and at the same time it hits the driven member 5, which descends, producing a tapping sound, which is damped by the driven member 5. .

When the driven member 5 is lowered and returned to its original state, the music synchronization switch 7 is turned on, and the rotary contact piece 8 rotated by the full-length axis 2 is connected to the printed pattern in sliding contact. The luminous body is lit,
The sound of the music box, the rhythmic beat, and the blinking of the light emitters are repeated.

The lighting time of the light emitters 17 to 20 is determined by the on/off time of the changeover switch whose rotary contact piece 8 is in sliding contact with the printed pattern to which each light emitter is connected and the music synchronization switch 7, especially the on time of the music synchronization switch 7. The on time is determined when the vibration valves 4b to 4d are not bent, and the vibration valves 4b to 4d are pushed up and flipped by the switch pins 3a to 3c, and from the moment when the driven member 5 descends to the next time. Switch pin 3
The lighting time is longer than in the conventional example until the vibration valves a to 3c and the vibration valves 4b to 4d engage and begin to bend upward. The ON time of each music synchronization switch using one vibration valve is, for example, 1 second, and by increasing the number of switch pins, the ON time can be adjusted to, for example, 1 to several seconds.

When the music box with a switch is configured as described above, the light emitters 17 to 20 can be made to blink in accordance with the music by using the integrated music box with a plurality of mass-produced vibration valves, thereby reducing costs. Furthermore, since the switch pins 3a, 3b, and 3c of the drum 3 are formed on the same drum 3 as the protruding pin 3d for the melody, the melody and the flashing of the light emitter and the tapping sound are completely synchronized, making it easy to align the position. There is no need to adjust timing or timing at all, making assembly extremely simple. Also, if you change the music box, you can easily synchronize the melody with the blinking and hitting sounds for other songs.

It is also possible to change the blinking color of the light emitters 17 to 20 by sequentially connecting light emitters of different colors, such as red, blue, . . . .

In the above description, the driven member 5 is made up of a plate conductor made of a leaf spring, and the music synchronization switch 7 is made up of the printed pattern 6a on the circuit board 6 and the bent part 5b. may be fixed, and the leaf switch may be turned on and off using the bent portion 5b of the driven member 5.

The switch pins 3a to 3c may be other suitable pins other than accompaniment pins.

The light emitting body described above may be used as another onomatopoeia or buzzer sound generating device, or may be a device with various electrical movements.

In the above explanation, when the drum 3 is unwound and the rotation of the drum 3 stops, the light emitters 17 to 20 may remain lit, but as a preventive measure, the present applicant proposed Utility Model Application No. 62-090801. By implementing the embodiment described in the specification, it is possible to reliably turn off the power when the engine is stopped.

Furthermore, when the music box with a switch of the present invention is commercialized, it may be placed in a gift box or the like, and a main switch may be provided in the electric circuit to turn it on and off.

Alternatively, the stopper of the speed governor and the main switch may be linked, as in the embodiment of Japanese Utility Model Application No. 60-11292 proposed by the present applicant.

In the above description, the drum 3 is rotationally driven by a full-length drive source, but it may also be driven by an electric motor.

[Effect of idea]

Since the present invention is constructed as described above, the ON time of the switch is extended, and a music box with an integrated vibrating valve for general mass production can be used. It is possible to provide a music box with a switch that has excellent practical effects such as easy assembly and reduced costs because the operations such as the above are easily synchronized and positioning and timing adjustments are completely unnecessary.
