The digital principle of operation and attendant amplifier efficiency benefits would remain. For example, instead of doubling the area of the next most significant diaphragm segment, it could simply be driven so it stroked twice as far. The next least significant bit drives a speaker of twice this area, and so on. The next least significant bit drives a speaker of twice the area (most often, but not necessarily, a ring around the previous driver), again to either full amplitude, or off. This allows for high efficiency in the amplifier, which at any time is either passing zero current, or required to drop the output voltage by zero volts, therefore in a theoretical ideal amplifier dissipating no power as heat at any time. The least significant bit drives a tiny speaker driver, of whatever physical design is chosen a value of "1" causes this driver to be driven full amplitude, a value of "0" causes it to be off.
