Abstract
An ear-wearable device includes a shell shaped for wearing in a user's ear. The shell comprises a tunnel wall shaped to define a tunnel that passes through the ear-wearable device. The ear-wearable device includes a receiver coil that is formed in or around the tunnel wall of the tunnel. The receiver coil is configured to inductively couple with a power coil via the tunnel and to inductively receive electromagnetic power from the power coil, and the receiver coil is configured to convert the electromagnetic power to an electrical current. The ear-wearable device includes one or more electrical components encased within the shell and configured to receive the electrical current from the receiver coil.
