I would prefer to post a reply to the following thread, because it is the thread that is linked from the Pinephone wiki,
https://forum.pine64.org/showthread.php?...8#pid85698
Unfortunately, as is common with mods in pretty much all online forums, some overzealous mod here closed that thread (and I, myself, was a mod in a very popular video and audio compression forum for many years, so I know the benefits of NOT wielding mod powers without good cause).
I'm sure plenty of Pinephone users with speaker problems will land on the older thread. However, after a couple of hours of speaker research, I consider the issue of obtaining a replacement speaker to be far from closed and, accordingly, I believe that the thread referenced by the wiki should not have been closed.
I have not been entirely happy with the replacement speakers that PB users have reported to work in these forums. They either use wires (must be soldered) or the spring contacts don't appear to be of the exact same PP OEM design, or the thickness/height of the speaker is not exactly 3mm, so I began my search for other replacement speaker source.
I found an N91 speaker on Ebay from Germany but it lacked technical documentation and I'd prefer to use a USA-based source too. I've very happy with Mouser Electronics purchases in the past and it looks like they have a new CUI Devices speaker available that should work in the PP.
In fact, Mouser has a number of 15 mm x 11 mm CUI Devices speakers. They are available in 2.5 mm, 3.0 mm and 3.5 mm heights/thicknesses. If I assume that 3.0 mm is the precise and correct dimension for a PP, this speaker should be the optimum PP replacement:

A Mouser search reveals many others but, for some reason, the spring mount selections do not appear in a Mouser search. I had to use duckduckgo to find the spring contacts version ("S" designator in the CUI part number) of the 3 mm speaker. Here are some other selections but keep in mind that "L" in the CUI part number is a wire connection and "SP" denotes a solder pad. (See the downloadable CUI .pdf datasheets for details):

Has anyone seen a link to a datasheet, vendor part number or mechanical drawing or CAD model for the actual PP speaker? I've already taken my inner-frame apart couple of times and I don't really want to remove it unnecessarily again in order to measure the speaker until I have a speaker in hand. I know the PP wiki says the speaker is 15 mm x 11 mm x 3 mm, but that "spec" doesn't have enough significant digits when spring finger contact pressure is at risk! Is it really 3.0 mm in height?
The alleged N91 speaker replacement from Aliexpress (linked above in this thread) is listed as 3.5 mm tall and its spring contacts are not quite the same design as the OEM speaker in my PP.
Here are CUI CAD files for the CMS-15113-078S-67 available from Mouser:

So the bottom line question is 3.0 mm or 3.5 mm for the PP?
