A directional characteristic of the pressure gradient transducers includes an omni portion and a figure-eight portion. The pressure gradient transducers have a direction of maximum sensitivity in a main direction. Each main direction of the pressure gradient transducers is inclined. The acoustic center of a pressure transducer and the pressure gradient transducers are positioned within an imaginary sphere having a radius that corresponds to double the largest dimension of the diaphragm of one of the transducers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Microphone arrangement having more than one pressure gradient transducer","description":"A microphone arrangement includes multiple pressure gradient transducers having an acoustic center, a first sound inlet opening leading to a front of a diaphragm, and a second sound inlet opening lead","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8472639","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.
