A soundbox is a stupid gimmick that ruins an adult collectible and turns it into a Playskool baby toy. Alternatively, it is an electronic gadget containing a memory device that records one or more sound clips and plays them back on demand, allowing for audible explosions, beep-wheedles, and "I am Optimus Prime". Soundboxes have also become somewhat cheaper to manufacture, given their very sparse use in lines previous to 2002. During Armada and after, the boxes became a common feature on larger figures.
