The test signal uses a brief frequency sweep signal such as a logarithmic sweep signal, in combination with a very low frequency (VLF) audio tone having a fundamental frequency below, e.g., 10 Hz. The very low frequency audio tone may have a sine wave shape, a square wave shape or a clipped sine wave shape."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Measuring loudspeaker nonlinearity and asymmetry","description":"Loudspeaker parameters are measured separately for various forward and rearward cone displacements, using a test signal that permits measurement of parameters at various degrees of either forward or r","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11272301","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.
