  • the figures illustrate more particularly, and in a nonlimiting manner, the application of the invention to a resonator 100 with an inertial mobile 1 which is a balance.
  • Each magnet 11, 12 carries a magnetic moment, it is an extensive vector magnitude which is calculated as the integral of the magnetization over the entire volume of the magnet.
  • the magnetic moment as the needle of a compass, which undergoes a torque when it is immersed in an external magnetic field.
  • the magnetic moment should consist only of the component ⁇ z which is aligned with the Z axis.
  • the total magnetic moment ⁇ tot is the sum of the magnetic moments of all the magnets carried by the resonator; this total magnetic moment should be aligned with the axis of oscillation D1, Z axis in the figure, to ensure the insensitivity of the resonator to external fields.
  • the vector ⁇ tot is the sum of a vector ⁇ xy representing the component of the total resulting moment in the XOY plane perpendicular to the Z axis, and the component ⁇ z on this same Z axis: in summary, we seek to minimize, and if possible to cancel the component ⁇ xy . Because this component ⁇ xy of the total magnetic moment ⁇ tot will change direction when the balance 1 oscillates.
  • the first proposed improvement therefore consists in adding at least one compensating magnet 4 on the balance 1, as visible on the figure 4 .
  • This is an additional magnet, which does not interact with the escape wheel 2, and whose component ⁇ c perpendicular to the axis of oscillation D1 is adjusted to be of equal intensity but in the opposite direction to the component ⁇ xy (perpendicular to the axis of oscillation D1) of the other magnets carried by the balance 1, as visible on the figure 5 , to compensate for the effect of the magnetic moment ⁇ xy .
  • the figure 5 shows that the total magnetic moment is then reduced to ⁇ z and is then aligned along OZ which corresponds to the axis of oscillation D1 of the balance 1.
  • micro-magnets magnetic pixels
  • a spherical-shaped magnet magnetized along the axis of oscillation which is in a spherical housing, as visible on the figure 10 , so that it can be tilted to create the component ⁇ c which is necessary for the compensation.
  • any other mechanical means of adjusting the direction of the magnet can be used.
  • each of these solutions for creating an adjustable compensation magnet is, advantageously, on board the balance 1, close to its axis of oscillation D1, as shown in figure figure 11 which takes over the configuration of the figure 7 .
  • the figure 12 shows a balance wheel 1 with magnetic vanes 11 and 12 which are magnetized along the axis OZ, with a resulting magnetic moment ⁇ z1 & 2 which is positioned at the magnetic center of mass of the vanes 11 and 12 (by analogy with the total mass of a mobile that is positioned in its center of mass).
  • the figure 13 illustrates the displacement of this same magnetic moment resulting in an inhomogeneous magnetic field B z , illustrated here for example with a field intensity gradient along X, represented by progressive shading.
  • the magnetic interaction energy varies non-linearly with the position of the balance 1 in this field.
  • the resulting magnetic moment is located on the axis of oscillation D1 (point O).
  • the magnetic paddles 11 and 12 which interact with the escape wheel 2 cannot be moved at this point.
  • a second improvement proposal therefore consists in adding a balancing magnet 6, as visible on the figure 14 .
  • This balancing magnet 6 is located opposite the escape wheel 2, relative to the axis of oscillation D1, and far enough from this escape wheel 2 not to interact with it.
  • This balancing magnet 6 is magnetized in the direction of the axis of oscillation D1. It is positioned opposite the position of the magnetic center of mass of the other magnets 11 and 12 on board the balance 1, like the show it figure 14 . In this way, the trajectory that the magnetic moment of the balancing magnet 6 described in the external field B z produces, at the first order, a disturbing torque which is opposite to that which applies to the other magnets 11 and 12 on board on the balance 1. Another way of explaining the role of this magnet is to speak of magnetic balancing. The objective is to bring back what can be called a magnetic center of mass of the magnetic moment on the axis of oscillation. This magnetic center of mass is defined by the first-order moments (x B , y B , z B ) of the component of the total resulting magnetic moment which is in the direction of the axis of oscillation D1.
  • this magnetic balancing magnet can be added with several methods. It should be noted that the geometry and the location of this balancing magnet can be calculated at the time of the design of the paddle magnets 11, 12, and the like. So the balancing magnet 6 can be manufactured with the same technology which makes it possible to manufacture the pallets: traditional machining, laser, thin film deposition, or the like. Another solution may be to add it in a second step, for example by projecting magnetic material onto the balance rim, by additive manufacturing or jetting, or by any other suitable process, to balance it. Of course, this list is not exhaustive.
  • the invention makes it possible to obtain good insensitivity of a resonator incorporating magnetic functions to external magnetic fields, without appreciable increase in the volume of its components, and at a moderate cost.
  • the invention is applicable both to new equipment and to mechanisms already manufactured, which can be improved under reasonable economic conditions, in complete safety.
  • the invention is described here in the particular case of a resonator, which is the most sensitive component of a timepiece, any disturbance of a magnetic order being capable of having direct repercussions on the rate by a degradation of this one.
  • the watchmaker will also know how to apply it to other less sensitive mechanisms of a watch, such as magnetic striking mechanisms, or others.
  • the invention has been described in the preferred case of a magnetic interaction, its principle remains applicable to an electrostatic interaction, or even a mixed magnetic and electrostatic interaction.
