Abstract (en)
[origin: CN104849994A] The invention relates to a frequency regulation method of a timepiece regulator via action on the rigidity of an elastic return means, and particularly a method of regulating the frequency of a resonator mechanism (1) around its natural frequency (omega 0). The mechanism includes an elastic return means (40) with a balance spring (4) or a torsion wire (46), wherein a regulator device (2) acts on this resonator mechanism (1) with a periodic motion to control a periodic variation in the real part and/or the imaginary part of the rigidity of this elastic return means (40), with a regulation frequency (omega R) which is comprised between 0.9 times and 1.1 times the value of an integer multiple between 2 and 10 of this natural frequency. This method being applied to a timepiece movement (10) comprising a resonator mechanism (1) of this type and including a regulator device (2) arranged to control a periodic variation in the rigidity of this elastic return means (40).
