12V to AAA Mp3 Player

I'm completely new to electronics. Hope that someone with good knowledge will help and guide me through the solution, step-by-step.

I have a common cheap mp3 player which can be connected to a USB port for battery charging and transfering of files. The mp3 player uses an AAA battery with 1.2V and 850mAh.

I need to connect this mp3 player to a Lead Acid 12V battery.
The current (mA) that the mp3 player consumes is unknown.

How do I do this? What do I need?
I would like to solve this problem in a cheap and easy way.

Thanks

Thanks for sharing your idea. Good to be considered very efficient and simple.

@birdman
I would like to eliminate the use of AAA batteries becasue since that I will be using this mp3 for long hrs, the battery duration won't last that much. And don't want to carry batteries with me! I only want 1 battery that connects everything (speaker, amplifier and mp3).

I would like to examine more ideas of what can I do...!?
