Abstract: An electric generator device includes a swinging part, a storage part, a vibration energy generating part, and an electric generator part. The swinging part swings in position due to external swing. The storage part stores a swing power of the swinging part. The vibration energy generating part generates, by the power stored at the storage part, vibration energy having its amplitude and frequency adjusted. The electric generator part converts the vibration energy generated at the vibration energy generating part to electric power. The vibration energy generating part comprises a pendulum to be in contact with a rotary part which is rotated by the power stored at the storage part, thereby to adjust the rotational speed of the rotary part.

Abstract: To provide an electric generator device excellent in power generation efficiency, and a timepiece movement and timepiece provided with the electric generator device. The electric generator device 5 comprises a swinging part 61A which swings in position due to external swing, a storage part 20A to store swing power of the swinging part 61A, a vibration energy generating part 40A to generate, by the power stored at the storage part 20A, vibration energy with its amplitude and frequency adjusted, and an electric generator part 70 to convert the vibration energy generated at the vibration energy generating part 40A to electric power. The electric generator device 5 is provided on a timepiece; the swinging part 61A is a rotary weight 61; the storage part 20A is a barrel wheel 20; and the vibration energy generating part 40A is an escapement governor 40. The electric generator part 70 is provided with a first electrode 71, a second electrode and an electret film.
