Actuator including a ferromagnetic jacket and at least one magnet embedded in the jacket including a length, a first end, and a second end. Each of the first and second ends of the magnet include a surface which is at least partially covered by the jacket. A ferromagnetic core comprises a length, a first collar-like protrusion, and a second collar-like protrusion. An electrically conductive coil through which an electrical current may flow is mounted to the core. The coil comprises a length. The coil is arranged adjacent the magnet and separated from the magnet by a gap. The length of the magnet is greater than the length of the coil. At least one of the coil and the magnet is movably mounted. At least one of the coil and the magnet is statically mounted. One of the coil and the magnet is capable of vibrating while the other of the coil and the magnet remains static.
