The voice coil comprises a main voice coil section, and a pair of auxiliary voice coil sections arranged along the travelling axis with auxiliary voice coil sections arranged respectively on either side of the main voice coil section. Applying an audio signal comprises continuously coupling a main driving signal based on the audio signal to the main voice coil and selectively coupling an auxiliary driving signal based on the audio signal to the pair of auxiliary voice coil sections. The disclosed embodiments further relate to a voice coil driving system and a loudspeaker comprising a voice coil driving system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Loudspeaker with dynamically controlled pairs of voice coil sections","description":"A method for driving a voice coil of a loudspeaker may include providing a magnetic circuit having an air gap, providing a voice coil suspended in the air gap, and applying an audio signal to the voic","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11240618","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.
