Title:
ELECTRO-ACOUSTIC TRANSDUCER
Document Type and Number:
WIPO Patent Application WO/2017/069057
Kind Code:
A1
Abstract:
In the present invention, provided is an electro-acoustic transduction film comprising: a polymer composite piezoelectric body obtained by dispersing piezoelectric particles in a viscoelastic matrix formed from a polymer material that displays viscoelasticity at normal temperature; and thin film electrodes laminated on both sides of the polymer composite piezoelectric body. Two or more layers of the electro-acoustic transduction film are laminated and the distance between adjacent electro-acoustic transduction films is 3 cm or less.
