A skin layer is formed on at least one of a front side and a rear side of the acoustic resistance material, and the skin layer has a higher density than that inside the acoustic resistance material, whereby acoustic resistance can be readily controlled."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Capacitor microphone unit and capacitor microphone","description":"The present invention relates to a capacitor microphone unit including a diaphragm, a fixed electrode that is arranged opposite to the diaphragm with a space provided between the diaphragm and the fix","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8526664","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.
