OG exemplary drawing
 
1. An electrostatic transducer comprising:
a back plate;
a membrane; and
multiple electrically driven cells, wherein each cell comprises multiple bottom electrodes, wherein at least two of said bottom electrodes are support electrodes and said support electrodes have a convex shaped top part.
 
7. A method for producing an electrostatic transducer according to claim 1, wherein the back plate is formed from an electrically non-conductive material and each support electrode of each cell is formed on the surface of the back plate by depositing an electrically conductive base and an electrically conductive top part.
