Your computer keyboard could soon be pumping out your favourite vibes.
British company New Transducers, developer of flat-panel loudspeakers, is now
using the technology to make keyboards generate hi-fi stereo sound (WO
01/31971). A thin plastic panel is mounted under the keys, with piezoelectric
transducers attached off-centre, near either end of the keyboard. Left and right
channel audio is fed to the transducers, flexing the panel in a complex pattern
to radiate stereo through the bottom of the keyboard, creating a wash of sound
without the need for separate speakers.
