Abstract
An electrodynamic acoustic transducer is disclosed, which comprises a frame and/or a housing, at least one coil and a magnet system, which is fixed to the frame and/or the housing and which is designed to generate a magnetic field through the coil. Furthermore, the electrodynamic acoustic transducer comprises a polygonal membrane, which in an inner portion is fixed to the at least one coil and which in an outer annular portion is fixed to the frame or the housing. A first distance between the outer annular portion and the inner portion at a longitudinal side of the polygonal membrane is smaller or greater than a second distance between the outer annular portion and the inner portion at a corner of the polygonal membrane.
