After my unsatisfying experience with the old TDMA 8260, I vowed to shy
away from tiny Nokia phones with miniature speakers. But I'd been looking
for an inexpensive, unlockable 850/1900 GSM phone for roaming in the US,
and came upon all the glowing reports on the 6590i's sound quality and RF
performance. Everyone said it had adequate earpiece volume, so I bought
one used on eBay. To my surprise it performs quite well in all.
But the phone was used and rather beat up, so I started looking at
replacement housings. I bought two no-name faceplate sets from different
vendors and was surprised/disappointed to find that I could barely hear
the phone even with the volume at maximum. What was so different between
these faceplates and the OEM Nokia?
The three speaker holes on all the faceplates are dead center, but the
phone's speaker is actually to the right of center. On the phone chassis
itself, there is a small rubber hood mounted onto the front of the
speaker, with a slitlike opening that directs sound from the top and side
of the speaker towards the earpiece.
On the inside of the Nokia faceplate, the plastic is scooped out
underneath the earpiece holes, in an irregular shape that encompasses all
3 holes as well as an extension towards the right, where the speaker
actually sits. A thin screen covers the entire scooped-out area, and keeps
dirt from entering the phone. Frankly, I can't see the purpose for all
this, especially when compared to....
One of my third-party faceplates simply has 3 holes with nothing to direct
the sound to them.
The other one actually has a circular foam rubber washer glued to the
inside, off center to the right, just like the speaker itself, with which
it mates when the faceplate is installed. To my enormous surprise ... the
volume when using this faceplate is actually LESS(!!!) than when using the
plain faceplate with no special mechanics.
I'd like to modify these faceplates to improve the volume they transmit.
So what is the secret to making a faceplate deliver the maximum earpiece
volume from a tiny Nokia speaker? I still don't have a clue.

Re: Earpiece Volume & Third-Party Faceplates
the std. nokia faceplate uses sound dynamics to reflect sound from the
speaker through a small chamber to your ear.
aftermarket ones do not consider this, the one with the rubber washer will
actively stop sound transmission, not help it.

That's exactly what I found; the plain plastic one was actually louder. Is
this "small chamber" the hollowed out area in the faceplate behind the ear
holes? It looks like the plastic is half-thickness in this area, but I
couldn't imagine how that could have such an effect on volume. I
guess I'm stuck with nokia brand faceplates until I can figure this out.
