We were talking about Bluetooth players and the speakers in them. Jason said his Bose Bluetooth speaker was not of the old paper cone, coil and magnet design and that it was the new technology. I said well I don't know but there has to be some moving part interfaced with air to produce sound. So I'm wondering is there a new way that speakers are made to produce high quality sound reproduction? I don't think a smartphone has a paper cone and magnet speaker.
