As normally conceived, loudspeakers use electrodynamic forces to control the movements of their diaphragms, which in turn move air. Matsushita Electric Industrial Co., Ltd. has come up with an interesting twist on this principle, one in which air pressure itself ("aerodynamic-drive technology") is used to control the diaphragm. The result is a transparent panel speaker called the "Sound Window," announced by the Japanese industrial giant March 27.

Digital audio is in no such danger, as evidenced by three new product announcements made the first week of April.
