Title:
POWER GENERATION APPARATUS
Document Type and Number:
Japanese Patent JP2013039021
Kind Code:
A
Abstract:
To provide a power generation apparatus which is suitable for the thickness reduction.
A power generation apparatus 50 includes: magnets 33A, 33B; a lower yoke 31 and an upper yoke 32 which are connected with the magnets 33A, 33B; and a coil 41 around which a coil wire disposed so as to face the magnets 33A, 33B or at least parts of the lower yoke 31 and the upper yoke 32 in the vertical direction is wound. The magnets 33A, 33B, the lower yoke 31, and the upper yoke 32 are integrated to form a movable unit 23 and the movable unit 23 vibrates against the coil 41. Thus, the thicknesses of the magnets 33A, 33B and the coil 41 are reduced and the power generation apparatus 50 which is suitable for the thickness reduction is provided.
