A shaker for transmitting vibrations to an application has a frame; magnet unit that provides a magnetic field in a gap; coil assembly including a voice coil mounted to a former. The former is attached to the frame at a former attachment surface and configured to position the coil in the gap, when the shaker is at rest. The magnet unit moves relative to the coil along an axis when the shaker is activated by supplying current to the coil. The magnet unit is suspended from the frame by a suspension arrangement including proximal and distal suspensions which interconnect the frame and magnet unit. The proximal suspension is closer to the former attachment surface than the distal suspension when the shaker is at rest. One of the proximal and distal suspensions has a stiffness K1, and the other K2, wherein K2>K1, and the ratio K1/K2 is 0.4 or less.
