<p>Vibrational apparatus capable of providing a vibrational output, said apparatuscomprising or including an assembly having a shuttle capable of shuttling betweencomplementary structures, at least one of which complementary structures providesthe vibrational output, the arrangement being characterised in that there isa drive to rotate the shuttle and there are magnetic interactions between therotating shuttle and the complementary structures such that interactions witheach complementary structure, and the phasing of the complementary structuresrelative to the shuttle, alternating magnetic results in the shuttling movementof the shuttle.</p> |
