Replacement earpiece fitting
Ok folks, I'm going through the process of replacing the earpiece speaker and loudspeaker, the bottom loudspeaker has succesfully gone in, the top earpiece speaker not to much . . . . . I've had the phone apart twice now, pretty straightforwards thanks to the how - to I followed on here, but clearly I've either not done something quite right or the speaker is wrong, I purchased a speaker off ebay described and recommended on here as "Earpiece Speaker For Nokia Lumia 435 500 530 610 625 720 820 920".
As you can see it sits pretty centrally, I've actually just adjusted it as it seemed over to the right so in the image(s) here it is pretty central, although I personally thought it seemed smaller than the original. Like I said, second time around and still not working, not sure how to progress so looking for somer guidance if anyone has any suggestions? I noticed the brass contacts seemed to be raised and the part that sticks up (on the original) looked to me to be at the bottom, so I am unsure if that was right or not as it seems I'm not getting any power at all to the speaker, but I can't make out where it needs to make contact exactly, or even if it matter which way up it is? Thanks. Dave

EDIT 29.11.2016
I'm now convincing myself that this is the wrong size speaker they've sent me, according to my logic, in the image below is the back of the PCB where the speaker should make contact, the USB point has a steel looking strap across it and below are two brass contact points, this 'HAS' to be the speaker contact points on the board surely? It seems to line up and I can't see what else they may be for?
In this image, I've sat the speaker on top with the contacts facing downwards, I can't conceivably see how the contacts on the speaker could possibly make any contact, it just doesn't seem wide enough, can anyone back my theory up from experience? I might as wel order another speaker and leave it in bits for the time being if so. . . . . . . . Thanks Folks. FWIW the speaker measures approx: 10x5x2.2mm and the hole it goes in measures about 12.5 x 6mm so there is an obvious gap all the way around the outer edge.
