PROBLEM TO BE SOLVED: To achieve amusement in an inexpensive and simple toy such as a small toy sold with a food product.SOLUTION: A function for generating a low frequency wave, such as an NFC mounted on a smartphone 4 is used, if wire length of a coil 2 is 28 cm or longer, by approaching the coil 2 to about 5 cm, to a generation source of the electromagnetic field of the NFC, weak electromotive force is generated between both terminals of the coil 2. At the time, a high luminance light emission diode 3 which is a load capable of operating by the weak electromotive force, is coupled to both terminals of the coil 2, and then is embedded in a monster toy 1. Then, the smartphone 4 is approached to the toy 1, eye parts in which the light emission diode 3 is embedded, emit light, so that the simple and inexpensive toy 1 which does not use a battery, can have amusement achieved by operation of power load, so that, commodity value of it can be improved.SELECTED DRAWING: Figure 1 |
