  • Publication number: 20230336932
    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.

  • Publication number: 20230031813
    Abstract: A magnetic connection can be formed between a magnet set of a first device and magnet set of a second device. The magnetic strength of the magnetic connection can be modified by changing an orientation of a magnet set of a first device from a first orientation to a second orientation. The magnet set or a case in which the magnet set is disposed can be asymmetric, such that alternating between the first and second orientations results in different magnetic connections.
