Magnetic conductive plates are attached to external surfaces of the permanent magnets. The housing includes a through-hole with a shape matched with the magnetic conductive plates, a wall of the housing has support steps located in the through-hole, and the magnetic conductive plates are placed in the through-hole and are fixed on the support steps."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Speaker","description":"A speaker includes a vibration system including a vibrating diaphragm and a flat voice coil for driving the vibrating diaphragm; a magnetic circuit system including two separated permanent magnets wit","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9774955","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.
