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.
Cette invention se rapporte à un film électromécanique servant à transformer de l'énergie électrique en énergie mécanique et de l'énergie mécanique en énergie électrique. Ce film (1) est diélectrique et il est formé de cellules (3), dont le rapport entre la hauteur et la largeur est compris entre 3/1 et 1/3. En assemblant deux de ces films et en régulant leurs caractéristiques, pour que l'intensité du champ électrique du premier film (1) diminue et celle du second film (1) augmente, on obtient un élément acoustique cintré.
