Microphone adapter

Hi!

First post here,
I'm working on an embedded project, where I need to adapt a 3 wire microphone with a 2 wire headset.

I need to use this electret microphone, and his tiny board (I cannot remove it, that's the challenge of this project) , with this receiver:

(Don't pay attention to the measurement)

I tried to power the tiny board with 3.3v but the SIG wire returns a pchhh and, I need to scream to have something more.

I really appreciate any help!
