The Speaker still is a piece of mechanics. This makes it inert, so only sounds until a certain frequency can pass. And exactly this is what we take advantage from. Instead of feeding it with its usual frequency spectrum, we use it with an essentially higher frequency, and switch it short in this frequency on or off, to get a resolution of 6 bits after all.
