Abstract
Systems and apparatuses are used to transmit data between external and internal portions of auditory prostheses or other medical devices. The external portion of the auditory prosthesis includes a magnet and an implanted coil that provides stimulation to the device recipient. A shaped shield material can be placed between the external coil and the sound processing hardware to improve efficiency and effectiveness between the external coil and implanted coil. Adverse effects on tuning frequencies can be reduced by disposing the shield material away from the magnet.
