When the electromagnetic speaker is mounted in a mobile phone, the diaphragm vibrates along a direction parallel to the screen, and the amplitude thereof will not be affected by the height of the mobile phone. In addition, the amplitude of the diaphragm at low frequency is greater than a normal speaker."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electromagnetic speaker","description":"The present disclosure provides an electromagnetic speaker including a frame having an elongated axis, a magnet assembly received in the frame, an elastic plate perpendicular to the elongated axis for","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9621993","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.
