A simple self-tuned mass damper is hereby proposed for a broadened frequency band and which can be adapted to large and expensive structures as well as small and inexpensive structures alike. The novel self-tuned mass damper includes an auxiliary mass and a non-linear suspension, which is configured to connect the auxiliary mass to a vibrating structure. The mass of the auxiliary mass and the stiffness of the non-linear suspension are selected such that the natural frequency is at least 6 Hz and that the amplitude of the relative displacement of the auxiliary mass in respect to the vibrating structure is at most 12 mm.Patent family as of 22.10.2021CN105612366 A 20160525 CN201480031708 20140602      CN105612366 B 20180406 CN201480031708 20140602      DE202014011406 U1 20200423 DE201420011406U 20140602      EP3004682 A1 20160413 EP20140734196 20140602      FI125726 B 20160129 FI20130005610 20130603      FI20135610 A 20141204 FI20130005610 20130603      JP2016521833 T2 20160725 JP20160517646T 20140602      JP6669648 B2 20200318 JP20160517646T 20140602      KR101777319 B1 20170911 KR20157035741 20140602      KR20160009062 A 20160125 KR20157035741 20140602      US10655699 BB 20200519 US20140895504 20140602      US2016123422 AA 20160505 US20140895504 20140602      WO14195575 A1 20141211 WO2014FI50442 20140602Link to current patent family on right </p
