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.

Abstract: Disclosed examples generally include methods and apparatuses related to microphone units, such as may be found in implantable medical devices (e.g., cochlear implants). Microphone units generally include a microphone element connected to a chamber having a concave floor with the chamber covered by a membrane. Microphone units can be configured to produce an output based on pressure waves (e.g., sound waves) that reach the membrane. In an example, a microphone unit has a pressurized gas within the chamber below the membrane such that, while in a static state, the membrane deflects away from the chamber floor.

Abstract: A bone conduction device includes split high-frequency and low-frequency actuators. The frequency response of the low-frequency actuator can be restricted to the lower range of hearing frequencies to improve performance. The high-frequency actuator can be implanted under tissue close to the cochlea to improve transmission efficiency, since high-frequency vibrations suffer greater attenuation.

Abstract: A coil, such as, by way of example, an inductance communication coil, that includes a conductor including a first portion extending in a first level and a second portion extending in a second level, wherein the conductor includes a third portion located on a different level than that of the second portion, wherein an electrical path of the conductor is such that the second portion is located between the first portion and the third portion.
