In the present invention, a multipole magnetic field enclosed by planes is formed by means of monopole equal-magnetic-plane magnetic fields in a multipole way, such that each pole face of an inductive diaphragm radiates sound waves with controllable power to any settable angular space at different angles; the diaphragms are driven to vibrate at the same time, so as to form more audio information, improving the power and efficiency of the loudspeaker, and increasing the response speed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multipole engine array system and loudspeaker","description":"The present invention provides a multipole engine array system and a loudspeaker, the multipole engine array system comprising a plurality of engine assemblies distributed in an annular array, the plu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11516593","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.
