Patent ID: 10999680

Abstract:
An electrodynamic acoustic transducer (1a . . . 1e) is presented, which comprises a housing (2), a membrane (3), a coil arrangement (6, 6a . . . 6h) attached to the membrane (3) and a magnet system (9, 10, 11). The coil arrangement (6, 6a . . . 6h) comprises a plurality of coils (7, 8) each having two terminals (T7a, T7b, T8a, T8b, T9a, T9b) being static in relation to the housing (2). Connecting wires (12a, 12b, 13a, 13b) connect the coils (7, 8) and the terminals (T7a, T7b, T8a, T8b, T9a, T9b, T78b). The connecting points (C7a, C7b, C8a, C8b) between the connecting wires (12a, 12b, 13a, 13b) and the coils (7, 8) are symmetrically arranged on the coil arrangement (6, 6a . . . 6h).
