Vibrational apparatus

Abstract

Vibrational apparatus capable of providing a vibrational output, said apparatus comprising or including an assembly having a shuttle capable of shuttling between complementary structures, at least one of which complementary structures provides the vibrational output, the arrangement being characterised in that there is a drive to rotate the shuttle and there are magnetic interactions between the rotating shuttle and the complementary structures such that interactions with each complementary structure, and the phasing of the complementary structures relative to the shuttle, alternating magnetic results in the shuttling movement of the shuttle.

         21 . Vibrational apparatus capable of providing a back and forth vibrational output, said apparatus comprising or including
 a shuttle having first and second ends,   a first complementary structure associating with the first end of said shuttle, and   a second complementary structure associating with the second end of said shuttle,   wherein there is a mechanical drive or mechanical drives to rotate the shuttle about an axis through said complementary structures,   and wherein magnets carried by the shuttle at each end and magnets carried by each complementary structure has the effect such that, under the effect of rotation caused interactions, the first end moves away from the second complementary structure and, in turn, the second end moves away from the first complementary structure,   and wherein the output of the vibration is from one or other, or both, of said complementary structures and not directly from the shuttle itself and is a back and forth output axially of, or parallel to, said axis.
