I was reading this and wondering if Dnote is a new and improved D class amplifier technology. The multi-coil speakers sound interesting, I wonder about the cost and manufacturing aspects though. Given this novel approach, it would seem to make a non-compatible audio system; will this be received well or face resistance due to the non-standard speakers?
Cool stuff! Not only save components but also evolve the speaker technology to a new high level! Intel is so smart in funding such technology and of course enjoy including such technology to the computer chipset without building anything analog!
A new and novel concept. Dnote do not use a D/A converter and amplifier. The digital signals are processed in a DSP chip and drives multiple coil loud speaker.The loud speaker itself works as a D/A converter. The prototype loud speaker has 8 coils.
