Hi guys.
Firstly, sorry if this question is far to easy for this section of the forums.
Basically, I was bored and decided to take apart a microphone I that I had just lying around.
It came with a box that you have to put the microphone through, which had the following circuit in it:

I'm just wondering if anyone could talk me through this circuit? Basically, the whole thing is powered by a 1.5V battery, and the signal comes from the microphone from the two inputs from the left on the diagram. The potentiometer controls the volume.. which I understand. However, can anyone explain:
- why the two outputs are connected via a resistor?
- why there is a need for a capacator (I'm guessing some kind of filter?.. but why?)
- why there is a second resistor separating the battery and the microphone signal in?
- why this circuit is required in the first place.
Any comments on this circuit would be a great help.. I really don't understand electronics =/ again, sorry for spamming the forum up with this easy stuff :S
