Abstract
The moving coil (voice coil) of the loudspeaker is so designed that the loudspeaker will become suitable for automatic production. For this purpose, the moving coil is positioned on a coilform, and as a connecting line extending to the ends of the moving coil there are used flexible ribbon conductors secured to a plastics carrier.
Claims7
Loudspeaker with a moving coil connected to a diaphragm in which elastic ribbon conductors serve as the lead in wires extending to the winding ends of the moving coil, with each ribbon conductor being connected on the one hand, to the moving coil and, on the other hand, to a stationary part of the loudspeaker, characterized in that the moving coil (1) is disposed on a portion of the longitudinal dimension of a cylindrical moving-coil carrier (2), with at least two flexible ribbon conductors (4) mounted on a plastics carrier (3) being disposed on the remaining portion of the moving-coil carrier parallel in relation to the longitudinal axis thereof, with the ends of said ribbon conductors being secured to said moving-coil carrier (2) with the aid of a thermosetting adhesive film (6), and that the ends of said moving coil are connected in an electrically conductive manner to these ends of said ribbon conductors.
