1. A drive unit comprising:
a magnet, wherein said magnet comprise a top surface and a bottom surface;
wherein said bottom surface comprises a base for supporting said magnet;
a coil, wherein said coil is configured to hingeably couple to said magnet;
a hinge, wherein said hinge is operable for hingeably coupling said coil to said magnet;
wherein a hingeable movement of said coil with respect to said magnet provides a reciprocating mechanical drive to said magnet;
wherein the hingeable movement of said coil is facilitated by providing a current pulsed supply to the coil;
wherein said hinge is configured to be operable for facilitating a pivotal movement of said coil with respect to said magnet; and
a resilient band, wherein said resilient band is configured to be operable for facilitating a return of said coil to said magnet after said pivotal movement of said coil with respect to said magnet.
