EAR-WORN ELECTRONIC DEVICE INCORPORATING DIRECTIONAL MAGNETIC ANTENNA
First Claim
1. An ear-worn electronic device configured to be worn by a wearer, comprising:
- a housing comprising a first end and an opposing second end, a first side and an opposing second side, and the first and second sides extending between the first and second ends, the first side configured to contact the wearer'"'"'s head;
a battery disposed within the housing proximate the first end;
an acoustic receiver or an acoustic receiver connector disposed within the housing proximate the second end;
electronics including a near-field magnetic induction (NFMI) radio disposed in the housing; and
a directional magnetic antenna situated in or on the housing and coupled to the NFMI radio, the antenna comprising a core having a complex shape and a coil wound around a portion of the core, the core comprising a closed end oriented toward a source of magnetic noise and an open end oriented away from the source of magnetic noise.

Abstract
An ear-worn electronic device includes a housing comprising a first end and an opposing second end, a first side and an opposing second side, and the first and second sides extending between the first and second ends. The first side is configured to contact the wearer'"'"'s head. A battery is disposed within the housing proximate the first end. An acoustic receiver or an acoustic receiver connector is disposed within the housing proximate the second end. Electronics including a near-field magnetic induction (NFMI) radio are disposed in the housing. A directional magnetic antenna is situated in or on the housing and coupled to the NFMI radio. The antenna comprises a core having a complex shape and a coil wound around a portion of the core. The core comprises a closed end oriented toward a source of magnetic noise and an open end oriented away from the source of magnetic noise.
