The electroacoustic transduction film includes a polymer composite piezoelectric body in which piezoelectric body particles are dispersed in a viscoelastic matrix formed of a polymer material having viscoelasticity at a normal temperature, and electrode layers interposing the polymer composite piezoelectric body therebetween, and an area fraction of the piezoelectric body particles in a contact surface with respect to the electrode layer is less than or equal to 50%, and thus the object is attained."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electroacoustic transduction film","description":"Disclosed is an electroacoustic transduction film suitable for a flexible speaker or the like, in which predetermined acoustic properties are able to be stably exhibited regardless of a bending state.","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9621997","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.
