ELECTROACOUSTIC CONVERSION FILM, ELECTROACOUSTIC CONVERTER, FLEXIBLE DISPLAY, AND PROJECTOR SCREEN |
| 摘要 |
The present invention provides an electroacoustic conversion film comprising: a polymeric composite piezoelectric body in which piezoelectric body particles are dispersed in a viscoelastic matrix formed of a polymer material exhibiting viscoelasticity at normal temperature; and two or more electrode pairs, wherein one electrode and the other electrode of each of the electrode pairs are arranged on two opposite main surfaces of the polymeric composite piezoelectric body, respectively, to interpose the polymeric composite piezoelectric body therebetween, and thereby each of the electrode pairs forms an active region. |
