Abstract
An electrodynamic acoustic transducer is disclosed, which comprises at least one coil with a coil wire being wound around a loop axis and a magnet system being designed to generate a magnetic field transverse to a longitudinal extension of the coil wire and transverse to the loop axis. Furthermore, the electrodynamic acoustic transducer comprises a membrane, which is fixed to the at least one coil and to the magnet system or to a frame/housing of the electrodynamic acoustic transducer. In addition, the electrodynamic acoustic transducer comprises a suspension system, which is fixed to the at least one coil and to the magnet system or to said frame/housing. In detail, the suspension system is fixed to the at least one coil in a region of a side wall of the at least one coil, which is oriented parallel to the loop axis.
