Claim:
1. An antivibratory suspension device for a mechanical assembly, the device comprising: a flapper performing pendulum motion, the flapper being provided with a mass support that extends from a distal end supporting at least one flapping mass to a proximal end, the proximal end being provided with a first hinge for hinging the mass support to a carrier structure for isolating; a second hinge for hinging a holder bar of the mechanical assembly to the mass support between the distal end and the proximal end; at least one dynamic force generator acting on an amplitude and phase of the pendulum motion of a flapper; a measurement system measuring a vibratory response of the carrier structure; and a computer in communication with the measurement system and the dynamic force generator, wherein the computer controls the dynamic force generator to adjust the amplitude and the phase of the flapper as a function of at least one measurement signal coming from the measurement system, wherein the at least one dynamic force generator includes at least one coil secured to the flapping mass and a magnetic mass, the magnetic mass being directly attached to the flapping mass by a resilient body.
