1. A vibration generator comprising:

  • a coil;

    a plunger including;

    a first shaft received in the coil such as to be movable in a first direction and at least partly made of a magnetic material so as to be magnetically attractable to the coil and thereby movable to one side in the first direction, anda second shaft extending in a second direction orthogonal to the first direction, being disposed on the other side in the first direction relative to the coil with a gap therebetween, and being at least partly made of a magnetic material so as to be magnetically attractable to the coil and thereby movable to the one side in the first direction; and

    a frame fixed to the first shaft at a position on the one side in the first direction relative to the coil, fixed to the second shaft at a position on the other side in the first direction relative to the coil, and elastically deformable at least partly as a result of movement of the first and second shafts.
