There is described a magnetic resonance device incorporating at least one first component part, which when the magnetic resonance device is operating oscillates, attached by at least one local load-bearing joint to at least one second oscillation-sensitive component part of the magnetic resonance device, where the joint has at least one actuatable facility for generating counter-oscillations which damp an oscillation of the first component part, where the second component part is a cladding element, in particular a vacuum cladding, which is affixed to the magnet via the joint, whereby a gap between the cladding element and the magnet is evacuatable, and the gap is provided with a pressure-isolating acoustically soft seal, in particular in the form of bellows.
