The diaphragm made of both crystallized and non-crystallized polyether-ether-ketone base films can have both an effectively improved acoustic performance and a lowered resonance frequency f0, thus, the acoustic effect of the loudspeaker can be improved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vibration system of a loudspeaker","description":"The present invention discloses a vibration system of a loudspeaker, comprising a diaphragm and a voice coil attached to one side of the diaphragm, wherein the diaphragm comprises at least two layers ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9838792","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.
