Abstract
A voice coil () for an electrodynamic actuator () is disclosed, which comprises a plurality of conductive open annular strips (A . . .) stacked over one another with insulation layers () in-between, wherein ends (Ea . . . Eh) of adjacent strips (A . . .) overlap in an overlapping zone (ZO) when viewed in a direction parallel to a coil axis (CA) and wherein adjacent strips (A . . .) are electrically connected to each other in a connection zone (ZC) within the overlapping zone (ZO). Ends (Ea . . . Eh) of the conductive strips (A . . .) are embodied as non-straight ends, and positions (P) of connection zones (ZC), which connect different conductive strips (A . . .), vary in a direction transversal to the circumferential direction (CD) in the overlapping zone (ZO). Moreover, a manufacturing meth-od for such a voice coil () and an electrodynamic actuator (), a speaker (), an electrodynamic transducer () and an output device with such a voice coil () are disclosed.
