Jorj, not really, those FunPhone guys are really smart. It turns out that the original 4048 had a Fast Fourier Transform module in it, and to save on reengineering, it was passed unchanged to the 8088, then to all future INTC processors, when they got the the first Pentium, someone noticed a weak FFT module and decided to soup it up, that new souped up FFT module, of course is in each of the next generations and souped up so well it can handle acoustic to digital (another type of A to D) transform on 18 parallel channels, that is what the geniuses at FunPhone have done. The CRT acts as a resonator transfering the vibrations (through the box' case and then through the motherboard's PCB) directly to the chip's pins and the rest is history, what a masterpiece. By the way, those of you that tried it on a portable will find it very touchy, because the AMLCD's acoustic response stinks.
