ELECTROMECHANIC FILM AND ACOUSTIC ELEMENT

An electromechanic film intended for transforming electric energy into mechanical energy and transforming me-chanical energy into electric energy. The film (1) is dielectric and formed of cells (3), the ratio of the height and width of which cells is between 3:1 and 1:3. By joining two such films to...

Zusammenfassung:	An electromechanic film intended for transforming electric energy into mechanical energy and transforming me-chanical energy into electric energy. The film (1) is dielectric and formed of cells (3), the ratio of the height and width of which cells is between 3:1 and 1:3. By joining two such films together and controlling them in such a way that in the first film (1) the electric field strength decreases and in the second film (1) the electric field strength increases, a bending acoustic element is provided.
