INTERFACING i378MV iBALL MIC TO AMPLIFIER CIRCUIT

Hello all,
Am in the process of designing a voice trained robot circuit..

For that I've built an amplifier...and it is working well..
(link to amplifier circuit that i built: **broken link removed** ... /Lab1b.pdf)

But, now I want to interface MIC to this circuit..

I thought of using i378MV iBall MIC for my application...
(**broken link removed** ... /cid:3270/)

Now I need a mechanism to connect this to the amplifier circuit..

It is a stereo one..I got it a jack from a local vendor(who knows nothing about the part number or anyother details)..

I attached the pictures of the connector which i got...

It has a rectangular object..at one end there is a provision to connect the MIC...to the exact opposite end there i find two pins..and to its right angle there is one more pin..

This is what I have..

I donno how to bias and connect this jack to my amplifier circuit..

Kindly help me in this regard..
