Title:
GENERATOR DEVICE, TIMEPIECE MOVEMENT, AND TIMEPIECE
Document Type and Number:
WIPO Patent Application WO/2015/029697
Kind Code:
A1
Abstract:
Provided are a generator device of exceptional generation efficiency, and a timepiece movement and timepiece provided with the power generation device. The generator device (5) has: a swinging part (61A) which swings in position due to external swing; an accumulating part (20A) which accumulates the swing power of the swinging part (61A); a vibrational energy generating part (40A) which, from the power accumulated by the accumulating part (20A), generates vibrational energy of regulated amplitude and frequency; and a generator part (70) for converting the vibrational energy generated by the vibrational energy generating part (40A) to electric power. The generator device (5) is provided to a timepiece, the swinging part (61A) constituting the rotor (61), the accumulating part (20A) constituting the barrel wheel (20), and the vibrational energy generating part (40A) constituting the escapement governor (40). The generator part (70) is provided with a first electrode (71), a second electrode, and an electret film.
