  • Vibration reduction device having acoustic meta structure
    Patent number: 11524637
    Abstract: A vibration reduction device having an acoustic meta structure mounted to a vehicle body and configured to block a structure-borne noise transmitted through the vehicle body may include a plurality of unit structures arranged at a predetermined interval therebetween, wherein each of the unit structures includes frame mounted to the vehicle body and configured to separate a predetermined space into a predetermined number of separate sections formed by walls of the frame; and a vibrator formed at a corner portion of each of the separate sections and each of which has a natural frequency to block a vibration transmitted from the vehicle body through the frame.
    Type: Grant
    Filed: October 25, 2019
    Date of Patent: December 13, 2022
    Assignees: Hyundai Motor Company, Kia Motors Gorporation, Katholieke Universiteit Leuven of KU Leuven Research & Development
    Inventors: Kyoung Jin Chang, Claus Claeys, Wim Desmet, Bert Pluymers, Elke Deckers, Lucas Van Belle, Noé Geraldo Rocha De Melo Filho

  • Vibro-acoustic attenuation or reduced energy transmission
    Patent number: 9275622
    Abstract: Vibro-acoustic attenuation or reduced energy transmission. The present invention relates to devices that display frequency zones of strong vibro-acoustic attenuation or reduced energy transmission. This can be used in particular, although not necessarily solely, in applications that require lightweight materials with good mechanical properties and good vibro-acoustic response or in applications that require materials with high sound reflection, absorption or sound isolation in a certain frequency band.
