Abstract

A membrane for an electroacoustic transducer is disclosed having a first area, a second area, which is arranged for translatory movement in relation to said first area, and a third area, which connects said first area and said second area, wherein local, planar spring constants along a closed line within said third area encompassing said second area, are determined in such a way that local, translatory spring constants along said line in a direction of said translatory movement are substantially constant or exclusively have substantially flat, mutual changes.
