The method for manufacturing the loudspeaker diaphragm comprises following steps: a. coating the silk fabric with a thermosetting adhesive under a high temperature, and drying the silk fabric; b. hot pressing and combining the silk fabric and thermoplastic polyurethane to form a membrane; c. pressing the membrane to form the dome portion and/or the suspension ring portion. The dome portion, or both the dome portion and the suspension ring portion of the loudspeaker diaphragm comprise silk fabric coated with a thermosetting adhesive and thermoplastic polyurethane. Thus formed loudspeaker diaphragm has good rigidity and damping characteristic, thus improving acoustic performance of the diaphragm."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Loudspeaker diaphragm and manufacturing method thereof","description":"A loudspeaker diaphragm, comprising a dome portion located at central position and a suspension ring portion located at edge position; the dome portion and/or the suspension ring portion comprise silk","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9838817","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.
