Abstract
A timepiece movement including, fixed on a same plate, a gear train subjected to a torque in a timepiece movement, and an energy storage to deliver a torque to the gear train for actuating a mechanical mechanism synchronizing rotational speed of the gear train with a resonator having a given natural resonant frequency included in the timepiece movement. The resonator is an annular resonator including a ring disposed around an axis. The ring is arranged to be periodically deformed under an action induced by motion of a drive member, included in this mechanism, and the drive member is driven in a pivoting motion, directly or indirectly, by the gear train.

31. A timepiece movement comprising:
-
fixed on a same plate, a gear train subjected to a torque in a timepiece movement, and an energy storage means to deliver a torque to the gear train for actuating a mechanical mechanism for synchronizing the gear train with a resonator having a given natural resonant frequency included in the timepiece movement, the resonator is an annular resonator including a ring disposed around an axis, the ring is arranged to be periodically deformed by an action induced by motion of a drive member, included in the mechanism, and the drive member is driven in a pivoting motion, directly or indirectly, by the gear train, wherein interaction between the drive member and the annular resonator is achieved by magnetic interaction means including magnets and/or magnetic poles, wherein the ring includes a plurality of a first number of magnets or magnetic poles, wherein the drive member includes a plurality of a second number of magnets or magnetic poles, the first number being different from the second number, so that the ring and the drive member together form a speed reducing or increasing mechanism. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55)
