1. A mechanical modulator, comprising:

  • first and second masses;

    a first spring connecting the first and second masses; and

    a second spring connecting the second mass and a fixed supporting end, wherein an motion input is applied to any one of the first and second masses while a resultant motion output is generated from the other one of the masses, and at least one of the springs has a nonlinear behavior characteristic that its stiffness varies according to a magnitude of the motion input.
