The set of SMI sensors includes a first SMI sensor configured to emit a first beam of light, and a second SMI sensor configured to emit a second beam of light. The second beam of light passes through the user input surface about an axis that is non-perpendicular to the user input surface. The processor is configured to adjust a parameter of the speaker at least partly in response to a first SMI output of the first SMI sensor and a second SMI output of the second SMI sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Self-mixing interference based sensors for characterizing user input","description":"An earbud includes a housing, a speaker mounted within the housing, a processor mounted within the housing, a user input surface on the housing, and a set of self-mixing interferometry (SMI) sensors m","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11243686","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.
