Therefore, the invention is an excellent safe earphone achieving highly radiation-proof, having high sound quality and noise reduction function."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Safe earphone","description":"A safe earphone includes a wired safe earphone and an over ear safe headphone, having plurality of speakers with different frequency responses respectively used for two ears to listen, so the frequenc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11284180","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.
