The second electrical signal is reversed in polarity to the first electrical signal. The electrical device further comprises a circuit connecting the first microphone and the second microphone. The circuit is configured to combine the first electrical signal and the second electrical signal in order to reduce the noise component in the first electrical signal with the second electrical signal that is reversed in polarity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electrical device for reducing noise","description":"An electrical device for reducing noise, comprises a first microphone configured to receive soundwave from a sound source and convert the soundwave to a first electrical signal including a noise compo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11477571","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.
