The light emission control signal outputting section outputs a first light emission control signal according to the detection signal, and outputs a second light emission control signal when a period in which the beat is not detected exceeds a set period, the second light emission control signal being for controlling the light emitting elements to perform a predetermined light emission mode."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Audio reproduction device","description":"Provided is a sound reproduction device including: speakers; light emitting elements provided to a part of each of the speakers, or in a vicinity of each of the speakers; a detecting section configure","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9832555","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.
