In an example, each pole piece assembly defines an airgap over a polarity transition region on a respective side of the magnet structure. First and second voice coils can be provided in respective ones of the airgaps, wherein each of the voice coils is coupled to a respective diaphragm assembly, and at least one acoustic tuning port can be configured to provide a damped acoustic communication path between first and opposite second sides of each diaphragm assembly."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Loudspeaker magnet and earphone assembly","description":"A dual-diaphragm loudspeaker driver assembly can include a multiple pole magnet structure, and first and second pole piece assemblies can be provided on opposite first and second sides of the multiple","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10469951","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.
