VIBRATION POWER GENERATOR

摘要

The purpose of the present invention is to increase electromotive force to be generated by relative motions between permanent magnets and coils. Provided is a vibration power generator equipped with: a plurality of permanent magnets (1, 2) that are integrated in a state of like poles thereof opposed to each other, and integrated so as to be separated from each other with a prescribed inter-magnet gap; and a plurality of coils (3, 4) that are arranged on the outer circumference of the plurality of permanent magnets, and arranged so as to be separated from each of the plurality of permanent magnets with a gap. The vibration power generator generates power by relative motions between the plurality of permanent magnets and the plurality of coils. In the relationship between the lengths of the coils and the permanent magnets that are opposed to each other, the length of the coils is longer than the length of the permanent magnets, and not longer than the sum of the length of the permanent magnets and the length of the inter-magnet gap.
