  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a child play tool using vibration power generation according to the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 1A and 1B, the child play tool 100 by vibration power generation in the first embodiment is mainly composed of the following components. That is, it includes a sphere 1, a shake-type piezoelectric element 2 that is housed in the space 3 of the sphere 1 and includes a piezoelectric film 2 a and a diaphragm 2 b, and an LED 4 that is electrically connected to the piezoelectric element 2. In addition, in this Example 1, since the rectifier is not used, the piezoelectric element 2 and LED4 are connected by the comparatively simple electric circuit.

  The sphere 1 is made of a translucent plastic material and has a space 3 inside. Of course, the sphere 1 is not limited to this shape. Any material that moves can be used, and the material is not limited to the above. However, it is desirable that the sphere 1 has a function of receiving an external force by hitting the floor surface and the like and transmitting the external force to the inside in a state where there is little reduction loss.

  The piezoelectric element 2 is preferably made of a relatively thin rectangular body as shown in FIGS. 1A and 1B and has a function of swinging by an external force action. The piezoelectric element 2 is disposed in a state where a base end portion is fixed to a base base 5 on which a circuit is formed. A weight 6 for increasing the deflection of the piezoelectric element 2 is fixed to the top of the piezoelectric element 2. However, the weight 6 may not necessarily be provided depending on the shape of the piezoelectric element 2.

At least two LEDs 4 are arranged on the base 5, and the LEDs 4 and 4 are connected to the piezoelectric element 2 by an electric circuit. The outline of the circuit structure is shown in FIG. Yes. The LEDs 4 and 4 are disposed with opposite polarities. This is because the directions of vibration of the piezoelectric elements 2 are opposite to each other, and the LEDs 4 and 4 can be lit in any direction, and this action eliminates the need for a rectifier.
Although the detailed structure is omitted, the piezoelectric element 2 is provided with a stopper 7 for adjusting the degree of deflection. However, the stopper 7 may be omitted depending on the shape of the piezoelectric element 2.

  The child play tool 100 using the vibration power generation having the above structure is subjected to an external force by hitting the whole against a floor surface or the like, and the piezoelectric element 2 causes a swinging motion as indicated by a dotted line in FIG. As a result, current is generated, the LEDs 4 and 4 are turned on, and as a result, the sphere 1 is illuminated.

  The colors of the sphere 1 and the LED 4 of the child play tool 100 by vibration power generation may be various, and are not particularly limited. The LED 4 may have a multicolor function and may change color depending on the magnitude of current.

  In the first embodiment, the vibration power generation unit of the child play tool 100 by vibration power generation is formed from the piezoelectric element 2 that swings, but the child play tool 100A by vibration power generation of the second embodiment is the ball 8 (marble). Is made up of vertical movements and back-and-forth movements caused by external forces generated by collisions and the like. That is, the ball 8 is movably accommodated in the cylindrical body 9, and the piezoelectric element 2 including the diaphragm 10 and the piezoelectric film 2 a is disposed above and below the cylindrical body 9. The piezoelectric element 2 is connected to the LED 4 via a rectifier 11 or the like.

  With the above structure, in the children's play tool 100A using vibration power generation, the ball 8 applies an external force to the piezoelectric element 2 by the movement of the ball 8, and an electric current is generated by the piezoelectric element 2, thereby turning on the LED 4.

  In the first and second embodiments, the piezoelectric element 2 is operated using vibration or impact force, but this embodiment uses air vibration (sound wave) generated in the space 3 of the sphere 1. The piezoelectric element 2 is placed on the base table 5 via the ring 15 and connected to the LED 4. With the above structure, the piezoelectric element is actuated by the sound wave generated in the space 3 and the LED 4 is turned on.

Each of Examples 1, 2, and 3 uses the piezoelectric element 2 as a vibration power generation unit, but Example 3 includes an electromagnetic derivative used as the vibration power generation unit.
The child play tool 100 </ b> B by vibration power generation includes a permanent magnet 14 movably disposed in a space 13 inside the coil 12. The coil 12 is connected to the LED 4 via the rectifier 11.

  With the above structure, the permanent magnet 14 is moved by the action of an external force to generate a current in the coil 12, and as a result, the LED 4 is turned on.

  The present invention consists of the contents of the above description, but the present invention is not limited to the contents of the above description, and of course, those of the same technical category are applied.

  The present invention is mainly created as a children's play tool, but of course, it does not have to be a child and can be used by elderly people, non-healthy people, etc., and its range of use is extremely wide. In addition, it can be used for a long time without using a battery, and since it is formed at a low cost, its range of use is clearly expanded.
