I have spent the last day dissecting iPhone and after analysing the circuitry of my device I can confirm the following relavatory fact:
The second iPhone speaker on the bottom of the phone is infact a microphone!
It turns out that the sound that I heard coming from this second 'speaker' was infact coming from the first speaker and my ears were cruelly deceiving me.
The bas*ards.
Has anybody noticed the earpiece sounds louder when holding to your left ear than right?
It is comments like this that threaten to ruin this fine community.
We are all here trying to conduct a serious discussion of the new and improved features of the iPhone 2.1 software update and we have to sit here and read this kind of tripe. It makes a mockery of everything that we, the apple generation, believe in and is frankly not acceptable on any level. Shame I tell you, hang your head in shame young man.
Everybody knows that the speaker is clearly louder when held to the right ear.
True with a dynamic mic, but less so with a condensor/electret as I suspect is in the iPhone. Also, the mic is connected to a preamp that would not work in reverse.Actually it could be theoretically possible to change a microphone into a speaker from a software update. A microphone IS a speaker, just reversed to take in sound, rather then send it out. So IT could be done with a software update, but the quality would be really low on it, unless they used the same speaker set for both sides.
