The present invention can increase the output of the forward acoustic wave actuation, decrease the output of the oblique acoustic wave within a center frequency bandwidth, and obtain a required directional characteristic. The present invention can be widely used in sound pickup (sound transmitting) applications."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sound receiving system","description":"A sound receiving system is disclosed, each of the plurality of basic array devices has an output terminal connected with one filter, each of the plurality of filters has an output terminal connected ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9736562","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.
