CrazCruz, your comment seems pretty ill informed.
ID is not about just making beautiful concepts, and MEs don’t design things, they engineer things (though they say design often).
A good industrial designer knows just enough about how things are made to be dangerous, not so much that he/or she is locked into doing things the way they always have been. While everyone’s role is slightly different, personally as a designer, I go to asia, work with manufacturers, sign off on tooling… I’m held responsible for everything from product definition to revenue once it hits market. Being produceable is critical.
Here is a project my team just finished. It is IPX rated, shock tested, dust sealed, has serious sonic requirements, and an array of attachment methods. On top of all of that it has a removable silicone skin. Understanding and working with all of that was key for the design team, even though on the surface it is just a simple speaker.
