or me this is like when all over india the idols of lord ganesha were drinking milk! its simple amazing. here is what happened.
my bro, surfing on the thoshiba laptop, came over to my room and asked me to accept the yahoo voice conv invitation. i said that i was on adium on my mac which doesnot supprt voice. i asked him what he was trying out. he said his friend told him that one can use a pair of ear phones as a mic simply by plugging it in the mic in port. i said "are u gone dumb! what kind of an electronics engineer are you". next thing i know i get an email which has a voice main over gmail from my bro. i can hear his voice! he calls me in his room and shows me how it works. now i know my toshiba doesnot have an inbuilt mic like my mac. but to be sure, i unplug the ear phone and try to do it again. it doesnot work. with the ear phones it does work! this were my ipod nano 2nd generation ear phones.
now, i plug the ear phones in the mic in jack of my mac. and from system preferance pane i see to it that Line in is selected and not in built mic. whoa! it does work.
but is it only with my apple ear phones? well no, even my aiwa ear phones work! i was wondering if those tine whole on the other side of the ear phone were working as a mic. but whatever it is, it makes no sense why someone would add mic to an ear phone. and from my knowledge of amplifiers, i know, its not possible for an out put device to record input whithout a sensor.
can anyone give me any insight?
