    Abstract: A suspension system (22) configured to minimize transmission of acoustic and vibrational energy in a device, comprising: (i) a rigid support (24): (ii) an operative element (16) positioned within the rigid support and comprising a drive frequency when the device is in operation; and (iii) a resilient element (26) engaging the rigid support and configured to create a resilient force against vibrations generated by the operative element in one or more degrees of freedom: wherein the natural frequency of a suspension mode in one or more of the degrees of freedom are tuned into a narrow resonant frequency range by the suspension, and wherein the resonant frequency is greater than the drive frequency.

    Abstract: A vibration-damping device includes a housing having a cylindrical mounting hole therein and a vibration-damping member provided in the mounting hole. The vibration-damping member includes an outer cylinder fitted into the mounting hole, an inner cylinder provided in the outer cylinder, and a rubber elastic body inserted between the outer cylinder and the inner cylinder. The rubber elastic body is formed with a bore penetrating in an axial direction thereof and a stopper protruding from a radially-inner wall surface thereof for the bore. The housing is formed with a receiving part which faces the stopper, in a radial direction of the mounting hole, across a gap.
