1. An apparatus for amplifying a vibratory movement, said apparatus comprising a micromechanical device, said device comprising:

  • an interface for fixedly joining the device to a vibrating member;

    a mass mounted so as to be mobile in at least one degree of freedom relative to the interface;

    a spring capable of exerting a return force between the mobile mass and the interface;

    an orientation-detecting member for detecting the orientation of the shift of the interface according to said degree of freedom; and

    a coupling member for coupling the mobile mass to the interface, wherein said coupling member is configured to couple the mobile mass to the interface when an orientation of shift of the interface is opposite that of the mobile mass and wherein said coupling member is configured to uncouple the mobile mass from the interface before a change in orientation of the interface and when the orientation of shift of the interface is identical to that of the mobile mass.
