Title:
ELECTROACOUSTIC CONVERTER FILM, FLEXIBLE DISPLAY, VOCAL CORD MICROPHONE, AND MUSICAL INSTRUMENT SENSOR
Document Type and Number:
WIPO Patent Application WO/2013/047875
Kind Code:
A1
Abstract:
Provided are: an electroacoustic converter film that has a polymer composite piezoelectric body obtained by dispersing piezoelectric particles into a viscoelastic matrix comprising a polymer material having viscoelasticity at room temperature, thin-film electrodes formed on both surfaces of the polymer composite piezoelectric body, and a protective layer formed on the surfaces of the thin-film electrodes; an image display device using the electroacoustic converter film; a vocal cord microphone; and a musical instrument sensor. As a result, it is possible to obtain a flexible speaker or musical instrument sensor or the like that have excellent flexibility, are capable of outputting stable sound even when the shape thereof is changed, and are capable of integration into a flexible display.
