The signal-processing system generates at least one of the first-order beampattern signals based on effects of the device body on an incoming acoustic signal. The microphone signals used to generate each first-order beampattern signal have an inter-microphone effective distance that is less than a wavelength at a specified high-frequency value (e.g., <4 cm for 8 kHz). In preferred embodiments, the inter-microphone effective distance is less than one-half of that wavelength (e.g., <2 cm for 8 kHz). In addition, the inter-phase-center effective distances for the different first-order beampattern signals are also less than that wavelength, and preferably less than one-half of that wavelength."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Spatial encoding directional microphone array","description":"In one embodiment, an article of manufacture has microphones mounted at different locations on a non-spheroidal device body and a signal-processing system that processes the microphone signals to gene","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10477304","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.
