Abstract (en)

[origin: FR2765647A1] The invention concerns a device reducing vibrations along an axis, in an extended frequency field, and with an optimum efficacy/mass ratio. In its simplest embodiment, it consists of a spring disk (60), two electromagnets (75), and a mass (76), contained in a housing (66), and comprises a vibration measuring sensor (91) and a controller (92).
