A hybrid movable coil plate for a flat panel speaker is characterized by including a spirally wound copper wire coil attached on one surface thereof and a PCB coil pattern-printed on the other surface thereof, wherein the copper wire coil and the PCB coil are formed in track shapes, a pair of lead wire connection ends are formed, and copper foils are formed in one or more via holes for electrical connection between the copper wire coil and the PCB coil, and in the vicinity of at least one among the one or more via holes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hybrid movable coil plate and flat plate-type speaker using same","description":"The present invention relates to a hybrid movable coil plate and a flat panel speaker, and more particularly, to a hybrid movable coil plate and a flat panel speaker which have improved acoustic press","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11528560","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.
