Membrane for an electroacoustic transducer

Image Number 5 for United States Patent #7866439.

A membrane (2') for an electroacoustic transducer (1) is disclosed having a first area (A1), a second area (A2), which is arranged for translatory movement in relation to said first area (A1), and a third area (A3), which connects said first (A1) and said second area (A2), wherein local, planar spring constants (psc) along a closed line (L) within said third area (A3) encompassing said second area (A2), are determined in such a way that local, translatory spring constants (tsc) along said line (L) in a direction (DM) of said translatory movement are substantially constant or exclusively have substantially flat, mutual changes.
