Mini Speaker Hamburger Type

A treat for your ears. This Hamburger Mini Speaker is a 3W speaker for any project needing a stand-alone sound. It has a built-in lithium polymer battery, a 3.5mm stereo jack, and two volume options. It might not be as good as JBL one, but for its price point the Hamburger won't break your bank. 

It is called Hamburger because you can twist the top and bottom halves of the speaker in opposite directions. Therefore, expanding it like an according to extend the bass reflex portion. It comes with a 1.5ft mini USB cable for recharging capabilities.

You can use this also for this FX board or for your Raspberry Pi 3 Model B+.
