Document Type and Number:
WIPO Patent Application WO/2014/157351
Kind Code:
A1
Abstract:
Provided is an electroacoustic conversion film having: a polymer composite piezoelectric body resulting from dispersing piezoelectric body particles in a viscoelastic matrix comprising a polymer material having viscoelasticity at room temperature; and at least two electrode pairs formed at an active region sandwiching the polymer composite piezoelectric body and respectively disposed at the opposing two primary surfaces of the polymer composite piezoelectric body. Further provided are: an electroacoustic converter using the electroacoustic conversion film; a flexible display; and a projector screen.
