At least part of a space formed between the first speaker and the second speaker communicates with the outside of the cabinet. When the speaker device reproduces the audio signal, the first diaphragm and the second diaphragm vibrate in opposite directions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Speaker device","description":"A speaker device for reproducing an audio signal includes a first speaker including a first diaphragm and a first magnetic circuit that drives the first diaphragm, where the first diaphragm reproduces","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9774935","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.
