I followed this video and managed to replace the broken piece without having to use a soldering iron:
I used a serrated blade to free the cable from the broken piece, being careful not to damage it (I think)
I put the new part in, I close everything but the left speaker (the one where I changed the part) doesn't work. All the controls on the earcup work perfectly (volumes, buttons, microphone), but it doesn't make any sound.
The soldering seems ok to me and the cable, apart from a small superficial cut, does not seem damaged.
What do you think could have happened?
I accidentally damaged the diaphragm while I was working: I placed it without realizing it on the screwdriver which was attracted by the magnet. From what I understand this could cause problems with sound distortions, or it could be the cause of the speaker not working at all
I attach photos of the welds, the cable and the damaged diaphragm
