Holding your cellphone so that the speaker is a few centimetres away from
your ear substantially reduces the microwave radiation reaching your head, so
Hassan Salam of Barnes in London (GB 2361138) has designed a cellphone that lets
you listen at a small distance. His phone is a clamshell design whose flip cover
has a speaker near the hinge. A plastic tube channels sound from the speaker
through the cover to an opening near the top. When the cover is flipped open,
you apply your ear to this opening, which has no electrical connection to the
handset’s microwave electronics.
