The stopper includes a conductive section electrically isolated from the fixed electrode and the movable electrode. The conductive section comes in contact with a front face of the fixed electrode or the movable electrode opposed to the stopper through deformation of the diaphragm."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Acoustic transducer","description":"An acoustic transducer has a back plate having a fixed electrode, a diaphragm that is opposed to the back plate with a gap interposed therebetween and that serves as a movable electrode, and a stopper","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9723423","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.
