Measures for sealing are then possibly only at a junction 312 or a passage point 211 required in which the electrical connection 31 . 32 between the electrical connection 3 and the voice coil 23 through the membrane 21 and the calotte 22 formed separation passes. The sealing of these points is simple and may not even be necessary if a separate passage is not provided (see in particular the embodiments according to 4d . 4e and 4g in which the first connecting section 31 completely front side and the second connecting portion 32 completely back of the membrane 21 runs and the connection point 312 only in a front-side or rear-side electrical contact of the first connection section 31 or the second connecting portion 32 with the membrane 21 or the dome 22 consists).

The invention is in no way limited to the embodiments of the subframe and the loudspeaker described above. In particular, an electrical connection according to the invention 31 . 32 between the electrical components and the electrical connection of a loudspeaker even with a loudspeaker possible, in contrast to those in 2 and 3 illustrated embodiments does not have integrated on a subframe speaker cage, but a structurally separate from the subframe, independently of the subframe functional function unit represents, which has its own loudspeaker basket and can be connected via separate fastening means to the subframe. In principle, the presented electrical connection can be used for any type of loudspeaker having a diaphragm and is also not limited to use for loudspeakers in vehicle doors.
