发明名称 FREQUENCY REGULATION OF TIMEPIECE RESONATOR VIA ACTION ON ACTIVE LENGTH OF BALANCE SPRING
摘要 PROBLEM TO BE SOLVED: To manufacture a time base that is as accurate as possible.SOLUTION: The invention relates to a method for maintaining and regulating the frequency of a timepiece resonator mechanism (1) around its natural frequency (ω0). A regulator device (2) acts on the resonator mechanism (1) with a periodic motion. The periodic motion provides a periodic modulation of the resonant frequency of the resonator mechanism (1), by providing at least one modulation of the active length of a spring comprised in the resonator mechanism (1), with a regulation frequency (ωR) which is between 0.9 times and 1.1 times the value of an integer multiple of the natural frequency (ω0), where the integer is greater than or equal to 2 and less than or equal to 10.
