Abstract: An external portion of an auditory prosthesis includes an external magnet that interacts with an implantable magnet to hold the external portion against the skin. Magnetic force generated by the stray field of these magnets can disturb the operation of a vibrating element of the auditory prosthesis. The technologies described herein utilize additional magnets disposed within portions of the auditory prosthesis to redirect the magnetic flux, which allows the vibrating element to be disposed more closely to the magnets, reducing the overall height profile of the prosthesis.
