| 摘要 | The invention relates to a timepiece resonator (6) comprising a train (7), swingably arranged about an axis (A), and a driver (8), subjected to a torque within a timepiece movement (10). Said resonator is a magnetic or electrostatic annular resonator (6), the train (7) of which is periodically excited by the movement of the driver (8). Said driver (8) is arranged such as to exert contactless force on the train (7). Said train (7) comprises a first amount of first pole shoes (76) magnetized or electrically charged according to a first step, and the driver (8) comprises a second amount of second pole shoes (86) that are magnetized or electrically charged according to a second step, different from the first step, and arranged such as to engage, via attraction or repulsion, with the first pole shoes (76) such that the train (7) and the driver (8) constitute together a speed reduction or multiplication mechanism. | ||||||
