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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ear-worn electronic device incorporating directional magnetic antenna","description":"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","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10511920","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
