Speakers on the iPhone. Different volume?

[0087215]

Hey guys!

I know it: the iPhone has only one speaker at the bottom,
but let me ask you this question. When I use YouTube or listen to the music,
I can hear that the sound is coming not only out of
the speaker on the bottom (which is placed near the dock
connector), but also from the spreaker you put your ear
on while calling. However the sound coming out of
that ear speaker is not that loud as the bottom speaker.

Do you know whether it is normal?

Thanks

All right. I thought so too. It is probably just the bottom speaker
that makes sound and it also comes out of the hole for
the ear speaker that is not active at that moment.
Thx!!!
