Electromechanic film and acoustic element |
摘要 |
An electromechanic film intended for transforming electric energy into mechanical energy and transforming mechanical 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. |
