There is a step-wise change in thickness at a location between the first location and the second location. Having greater thickness at the periphery of the dome-shaped member may improve stiffness of the diaphragm and may allow for an increased break-up frequency. Having thinner material elsewhere in the dome-shaped member may allow the mass of the diaphragm to be kept low and may result in better acoustic sensitivity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Diaphragms for loudspeaker drive units","description":"A diaphragm for a loudspeaker drive unit or for a microphone includes a rigid dome-shaped member having a thickness that varies from a first thicker thickness at a first location at the periphery of t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9609437","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.
