ABSTRACT:
According to the invention, a contact for loudspeakers (10) is indicated between the wire ends (24) of voice coil (16) and the stationary contacts (19), which is temperature-stable even above 250.degree. C. This is achieved by first conductively connecting the wire ends (24) to the connecting lines (21), and then attaching the connected parts (21, 24) at least to one side of a high-temperature-resistant plastic foil (25). The plastic foil (25) is affixed to the diaphragm (13) or the voice coil support (14) by mechanical attachment means (23). The fact that the plastic foil (25), which stabilizes the connecting lines (21), is installed afterwards, allows the connection between the wire ends (24) and the connecting lines (21) to be performed by the ultrasonic welding technique.
