Abstract
A bone conduction device configured to couple to an abutment of an anchor system anchored to a recipient's skull. The bone conduction device includes a vibrating electromagnetic actuator configured to vibrate in response to sound signals received by the bone conduction device, and a coupling apparatus configured to attach the bone conduction device to the abutment so as to impart to the recipient's skull vibrations generated by the vibrating electromagnetic actuator. The vibrating electromagnetic actuator includes a bobbin assembly and a counterweight assembly. Two axial air gaps are located between the bobbin assembly and the counterweight assembly and two radial air gaps are located between the bobbin assembly and the counterweight assembly. No substantial amount of the dynamic magnetic flux passes through the radial air gaps.
