The condenser microphone unit includes a first pipe extending forward on the front side of a diaphragm and a second pipe arranged so as to surround the first pipe. A front acoustic terminal communicating with a front surface of the diaphragm is formed on an inner side of either one of the first pipe or the second pipe. A rear acoustic terminal communicating with a back surface of the diaphragm from the rear side of a fixed electrode is formed on an inner side of the other pipe."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Condenser microphone unit","description":"In a primary sound pressure-gradient type condenser microphone unit driving a diaphragm by difference in sound pressure applied to acoustic terminals in front and back of the diaphragm, a drive force ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9693151","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.
