Definitions

  • the present invention relates to a coupled resonator for a control system, that is to say an assembly formed of two oscillators whose coupling makes it possible to stabilize a frequency and thus to make it more independent of external stresses.
  • the invention will be more particularly illustrated by the regulating system of a clockwork mechanical movement for which isochronism is a quality factor.
  • the present invention therefore aims to overcome the disadvantages of the aforementioned prior art by providing a coupled resonator of simpler and more reliable design.
  • the invention relates to a coupled resonator comprising a first low frequency resonator for example of the order of a few hertz and a second resonator at higher frequency, for example of the order of one kilohertz.
  • the invention is characterized in that the first resonator and the second resonator comprise permanent mechanical coupling means, said coupling making it possible to stabilize the frequency in the event of external disturbances, for example in the event of shocks.
  • the two resonators can be manufactured separately from identical or different materials, and then mechanically assembled by any means known to those skilled in the art, such as bonding, riveting, welding or interlocking.
  • Both resonators can also be made in one piece in a single material.
  • the materials used must have a certain elastic constant and may, for example, be chosen from metals or alloys, or amorphous, monocrystalline or polycrystalline materials, such as glass, quartz and silicon or its derivatives.
  • the invention will be more particularly illustrated by a coupled resonator formed by a hairspring and a tuning fork, such a resonator being able to be integrated in the regulating system of a timepiece, in particular a wristwatch capable of receiving shocks.
  • the invention will be more particularly illustrated by the coupled resonator shown in Figure 1 to maintain the isochronism of a mechanical watch movement.
  • the hairspring 1 basically comprises a first resonator consisting of a hairspring 1 typically having a frequency of the order of a few hertz and a second resonator consisting of a tuning fork 2 typically having a frequency of the order of one kilohertz.
  • the curve inside 3 of the hairspring 1 is fixed in a conventional manner on a ferrule 5 for securing to a balance shaft and the tuning fork 2 also includes two arms 4, 6 connected by a foot 8.
  • foot 8 of the tuning fork 2 is fixed in known manner to a fixed part of the watch movement, such as the rooster.
  • the hairspring 1 and the tuning fork 2 are mechanically connected permanently.
  • the arm 6 of the tuning fork 2 is extended by the curve on the outside 7 of the hairspring 1.
  • the two resonators are made in one piece, by known techniques that depend on the materials used. These materials are obviously materials having a certain elastic constant "k”. such as metals and alloys, or amorphous materials, monocrystalline or polycrystalline, such as glass, quartz, silicon or its derivatives.
  • This basic embodiment will further illustrate an example of how such coupling has a favorable effect on the stabilization of the frequency.
  • the first resonator namely the hairspring 1
  • the second resonator namely the tuning fork 2
  • the arm 6 of the tuning fork 2 comprises a notch 10 in which the end of the curve outside the spiral 7 is engaged, possibly completing the mechanical connection by gluing.
  • the foot 8 of the tuning fork 2 further comprises a constriction 12 for fixing to a fixed part of the watch movement, and which can influence the coupling constant "k c " between the two resonators.
  • FIG. 3 represents other variants allowing a great freedom to adjust the coupling constant "k c " between the first and second resonators.
  • the foot 8 may comprise material recesses which will make it possible to modify the coupling constant "k c ".
  • These recesses 14 may for example be made by laser ablation. They could also be done on any other part of the tuning fork 2, in particular on the free arm 4 to modify the mass "m” and therefore the natural frequency of the tuning fork, Conversely, according to an embodiment not shown, it would be possible to add mass to a any place of the second resonator.
  • FIG. 3 also shows another variant, which can be combined with the preceding variant, to modify the natural frequency of the first resonator.
  • the free arm 4 comprises in fact a counterweight 16, movable on said arm 4 and can be immobilized at a determined location, for example by means of a clamping screw 18.
  • the tuning fork 2 when the tuning fork 2 is made of quartz along crystallographic axes for obtaining a piezoelectric effect, electrodes may be provided on the arms 4, 6 to generate electrical energy. In the case of a wristwatch this energy may for example be used to illuminate the dial.
  • the value of the coupling constant "kc" depends on the shape of the foot that joins the two resonators.
  • This coupling frequency k c was varied between the values 1.10 -8 and 1.10 4 and represented in FIG. 4 with a logarithmic scale the natural frequencies of the coupled system.
  • the highest frequency f 2 is practically unaffected by the variation of the coupling coefficient k c , while an increase of the lowest frequency f 1 is observed for the weakest couplings that is, those that are most relevant to this application.
  • the graph of FIG. 5 corresponds, as a function of a variation of the coupling coefficient k c within the limits indicated above, to a perturbation study on the first resonator, for example due to a shock, ie to a comparing the effect of the perturbation on a frequency variation of the first resonator when it is alone and when it is coupled with the second resonator, which is assumed to be stable.
