Abstract
An electrodynamic acoustic transducer () is presented, which comprises a housing (), a membrane (), a coil arrangement () attached to the membrane () and a magnet system (). The coil arrangement () comprises a plurality of coils () each having two terminals (T, T, T, T, T, T, T) being static in relation to the housing (). At least one pair of coils () has one terminal (T) in common, whereas the remaining terminals (T, T, T, T, T, T) are individual terminals (T, T, T, T, T, T). Connecting wires () connect the coils () with the individual terminals (T, T, T, T, T, T), and a conductive layer or path () attached to the membrane () electrically connects the coils () with the common terminal (T).
