By virtue of the configuration mentioned above, the electromagnetic speaker has a small form with a reduced height. Further, greater driving force is generated by the magnet driving the vibrating plate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electromagnetic speaker","description":"An electromagnetic speaker is disclosed and includes a frame having an elongated axis, a magnet magnetized along a radial direction and received in the frame, a voice coil fixed relatively to the fram","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9820051","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.
