An electrodynamic actuator () for a plate like structure () or membrane () is disclosed, which comprises a voice coil (), a magnet system () and a plurality of arms () coupling the voice coil () and the magnet system () in a movable manner. The arms () are made of a metal with a fatigue strength of at least 370 N/mmor an ultimate tensile strength of at least 1100 N/mm. Each of the arms () comprises at least two arm sections (s, s, s), which are arranged movable to each other, and which are connected to each other by means of a damping material () with a tensile storage modulus of 0.1-6000 MPa and a tensile loss factor of at least 0.1, each measured at room temperature of 20° C. Moreover the invention relates to speaker () and an electrodynamic transducer () with such an electrodynamic actuator () and a method of manufacturing an intermediate product for such an electrodynamic actuator ().
