Description

DETAILED DESCRIPTION OF THE INVENTION The present invention vibrates a diaphragm using an oscillator with an electronic circuit, a magnetism generating coil, and a magnet, and uses the resulting vibration as power to scatter colored elastic beads, Furthermore, it relates to a display device that uses the kinetic energy of the scattered elastic globules to move an arbitrary display object, and its purpose is to create a display device that uses a small amount of power and is rich in dynamic effects. Our goal is to provide the following.

Conventionally, in display devices that have a moving display object, small motors, pendulums using magnetic repulsion, wind pressure, rising air currents, water pressure, etc. have been used as means for moving the display object, but all of these methods consume less energy. The energy loss is large and it is uneconomical, and furthermore, due to the configuration of the device, there are restrictions on the shape, dimensions, etc., so it is difficult to make it smaller and lighter.

The inventors of the present invention have conducted various studies to improve the drawbacks of the above-mentioned conventional products, and have particularly researched novel means for moving display objects.
By using the magnetic vibration force of an oscillator generated by an electronic circuit as power to make a small elastic ball fly up, and by using the kinetic energy of the small elastic ball, that is, the collision force of the small elastic ball, a display object can be moved with a small amount of power. Based on this finding, the present invention has been completed.

That is, the present invention electrically connects an oscillator or AC power supply using an electronic circuit to a magnetism generating coil, and connects either the magnetism generating coil or the magnet to one side of a diaphragm having an elastic body on the opposite side. Alternatively, a diaphragm made of an elastic body itself has a built-in magnetic vibration means, and a vibration power generating section is formed on the upper surface by exposing the surface of the elastic body at the bottom of a funnel-shaped saucer. On a stand that also serves as a case, a transparent hollow body having an arbitrary number of appropriately colored elastic spheres and a movable display object inside and an opening at the bottom is placed between the opening and the above. The magnetic vibration is characterized in that the display object is moved by using the kinetic energy of elastic small spheres that are provided so as to be connected to the peripheral edge of a funnel-shaped saucer and that fly up due to vibrations of the elastic body. This is a display device used for power.

Next, the present invention will be explained in detail based on the drawings.

FIG. 1 is a perspective view of an embodiment of a display device using magnetic vibration as power according to the present invention, and FIG. 2 is an explanatory cross-sectional view thereof. 1 is an oscillator based on an electronic circuit, which is installed on the top surface of the bottom cover 18 of the case/stand which has vibration prevention packing 19 on the bottom surface, and one of its terminals is connected to the dry battery holder 1.
It is connected to a dry battery 16 fixed to 7 and a power switch 2. On the other hand, the other terminal is connected to the case-cum-base 12
It is connected by a connecting wire 4 to a magnetism generating coil 3 installed on a vibration prevention/sound insulating plate 13 fixed to the upper part of the magnetic field.

This connected magnetism generating coil 3 has a magnet 5 on its lower surface which is provided close to its upper surface.
A vibration power generating section 10 is constituted by a diaphragm 7 having an elastic body 6 on its upper surface, a supporting coil core 8 supporting the diaphragm 7, a core support base 9, and the like. (See FIG. 3) The elastic body 6 located at the uppermost end of the vibration power generating section 10 is arranged so as to be located within the lower opening of the funnel-shaped saucer 11 provided at the upper end of the case/stand 12, and to form a power source for scattering small balls.

Next, a transparent hollow body 15 having an opening at the bottom is placed on the case/stand 12 having the funnel-shaped saucer 11 at its upper end so that the opening and the upper edge of the funnel-shaped saucer 11 are connected. It is placed or fixedly provided, and an arbitrary number of appropriately colored elastic balls 14 and a desired movable display object 23 are inserted or arranged inside the display. Thus, a display device using magnetic vibration as a power source according to the present invention is formed.

As the oscillator using the electronic circuit in the present invention, for example, as shown in FIG. 4, a method of feeding back the magnetic electromotive force to cause oscillation can be used. In this case, there is an advantage of low power consumption, for example, the input voltage is 1.5 volts. Current consumption is 8mA in case of
It is possible to operate at a certain level. In the figure, _L1 is a coil that generates an attractive force, and _L2 is a coil that generates a magnetic electromotive force, and both are wound around the same iron core. E is a battery, 2' is a switch, R ₁ is a resistor, D ₁ and D ₂ are check diodes, TR ₁ is a switching transistor, 5' is a magnet such as ferrite, 7' is a diaphragm (leaf spring), 6 ′ is an elastic body. A light material such as rubber, styrofoam, or cork is suitable for forming this elastic body, but a heavy material such as rubber is not suitable because it makes it difficult for the diaphragm 7' to vibrate sufficiently.

In addition to the above oscillator, a multivibrator oscillator as shown in FIG. 5 may be used. In this case, the magnet 5'' is fixed, and the coil 21 and spring 20 generate vibrations.This method is similar in principle to the voice coil of a speaker, but the coil and case are integrated and supported by a spring. The difference is that the elastic body is fixed and the elastic body is fixed.

When using this oscillator in the present invention, the larger the vibration amplitude, the more effective it is, so by supporting it with a spring, a larger vibration amplitude can be obtained. For example, if you use a speaker, you cannot make a sphere fly up at all, and even if you apply high-output electrical energy to a speaker, it will only fly up a few millimeters. In the figure, 5'' is a magnet, and 6'' is an elastic body, which is preferably made of a light material as described above. 22 is a plastic cap with a coil glued inside it, 21 is a coil, 7″ is a flexible soft wire, R ₂ to R ₅ are resistors, C ₁
~ _C2 is a capacitor, _TR2 ~ _RT3 are oscillation transistors, _TR4 is a power transistor, and _D3 is a check diode.

In addition to the above-mentioned oscillators, examples of oscillators that can be used in the present invention include a bridge oscillator, a blocking oscillator, etc. Similar effects can also be obtained by using other commercial AC power sources.

In addition to using these oscillators, it is also possible to change the movement of the displayed object by changing the sound given from an external source, such as a record, radio, tape recorder, or directly given sound, into a voltage change. It is possible.

Next, the vibrating pieces 7, 7', 7'' each provided with the elastic bodies 6, 6', 6'', etc., have at least an appropriate size and shape depending on the form and structure of the vibration power generating section 10. It is made of an elastic material (such as a leaf spring) and has an elastic body of an appropriate shape, such as cork, styrofoam, or foamed polyethylene, on one side or end of the elastic material, and a magnet on the other side. be. The vibrating piece may also be made of an elastic body with a magnet attached to one end.

Further, the funnel-shaped saucer 11 is for collecting the elastic particles 14 that fly up and falling and sending them smoothly to the surface of the elastic body 6 at the bottom of the center. The opening angle and opening area of the funnel may be selected depending on the weight, etc., and the opening angle is normally preferably 60° to 120°.

Furthermore, as a result of experiments using various materials for the elastic small balls 4, it was found that those having a density (g/cm ³ ) of 0.01 to 0.04 jump best. Since a certain degree of repulsion is required, for example, foamed polystyrene balls are most suitable for these conditions, and foamed polyethylene balls can also be used.

When using these elastic balls, they are colored appropriately and, for example, 18 styrofoam (density = 0.027 g/cm ² ) spheres are used as small balls with a diameter of 3.5 mmφ to 4 mmφ. Using the one in Figure 4, the input voltage is 1.5 volts, the consumption current is 8 mA,
When operated with a power consumption of 0.012 watts, the Styrofoam pellets can be launched up to a height of 250 mm. Furthermore, by increasing the voltage to 6 volts and increasing the power consumption to 0.25 watts, it is possible to soar to a maximum height of 450 mm. The frequency of the oscillator used at this time was 3000 Hz, but this applicable frequency range is wide and can be used from as low as 50 Hz if conditions are selected. Then the frequency is 1000
The best efficiency results are shown at ~3000 Hz.

As the transparent hollow body 15 in the present invention, for example, a transparent glass bulb with an opening at the bottom or a transparent plastic case is suitable. Applicable. In addition, the latter half of these transparent hollow bodies can be made to have a mirror surface in order to enhance the display effect. In this case, the flying elastic balls 14 and the display object 23 can be seen reflected on the mirror surface, adding even more variation. It is suitable for

Furthermore, the movable display object 23 provided in the transparent hollow body 15 can have various shapes. For example, in the case of something like a rubber balloon as shown in Figure 1, it floats in the air due to the collision of small elastic balls, and in the case of something like a UFO-shaped disk model as shown in Figure 6. The disk body is made of a light material such as sponge rubber, and the disk body is provided with at least a plurality of blades 25, preferably a large number of blades 25, inclined in the same direction around the disk body, so that the disk body can rotate freely. In this case, when the elastic small balls 14 collide with the blades 25, the blades 25 receive stress in one horizontal direction, allowing the disk to rotate.

Furthermore, as shown in FIG. 7, a plurality, preferably a large number of metal tube wind chimes each emitting a different tone may be hung from above as the display object 23''; in this case, The flying elastic ball collides with the metal tube, causing the metal tube to sway and producing sound.Therefore, the elastic ball hits the wall of the transparent hollow body 15 at an appropriate position or above the transparent hollow body 15. Through hole 25
It is sufficient to guide the internal sound to the outside by providing a.

Since the present invention has the above configuration, it is possible to scatter small balls and use the kinetic energy of the small balls to move display objects of various shapes and make sounds. It has a variety of novel display effects, and uses an electronic circuit oscillator, dry batteries, etc. as the power source, making it easy to miniaturize the device and making it convenient to carry, making it extremely economical and practical. It has great utility as a display device.
