Broken headphones (Sennheiser HD202II)

[gitsNital]

Hello all! I've had these headphones (Sennheiser HD202II) for ten years and I love them. I've fixed (re soldered the wires) a bunch of times, but this time I think they're broken beyond repair. Unfortunately I don't have money to buy another ones so I'm hoping someone can help me figure this out.

The "plaque" (sorry, I don't know the term), that the wires are soldered to, came off. But what I can't figure out is that it is not connected in any way to the main speaker. It looks like there is a brownish transparent glue (which I can't imagine it being conductive). As far as I can see, it was glued to the black plastic (the "case" of the headphone).

Please, any comment or suggestion on what to do is much appreciated. There are pictures attached, but I can take more if needed.

I'd say that speaker is beyond repair; coil windings are connected to that part and it would be VERY tedious to repair it. Coil windings are lacquered so repairing would involve scraping that off small amount, solder back to connector (that u-shaped one) and gluing that connector back to case.

edit: I'm not 100% sure of construction of headphone speakers, but this info was based on normal speakers, I can't see connection either between that plaque and speaker windings.

There should be a VERY fine wire which connects from the solder pads on the "plaque" to the coil which is around the magnet in the centre of the speaker.

If you cannot find, and connect to these fine wires, then as fezder has said, the speaker is beyond repair.

Well, after reading your comments I took out the speaker itself from the case, and you were right. There were two wires. I tried extracting them but it's impossible, they are extremely thin. Even if I extracted them, there would be no way of soldering them (at least not with the tools I have).

Anyways, thank you for taking the time to reply.

This is a sad sunday. I took more pictures in case anyone in the future needs them.
