The acoustic transducer includes a stationary electrode plate, and a vibration electrode plate facing the stationary electrode plate with a space between the electrode plates. The vibration electrode plate includes a slit that allows sound to pass through. The vibration electrode plate includes a resistance increasing section including at least one pair of high-resistance surfaces that constitute side surfaces of the slit in a width direction thereof, and are thicker than a middle portion of the vibration electrode plate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Acoustic transducer and microphone","description":"An acoustic transducer includes a slit having higher passage resistance than in conventional structures and having a lower rate of decrease in the passage resistance than in conventional structures wh","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9641939","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.
