1 Kiyosei SHIBATA Ryousuke SOU Masahito KAWAI Abstract The "ECLIPSE TD" series, Fujitsu Ten home audio system, is based on "Time Domain Theory" that is different from the conventional theory, and has been highly praised in various fields beyond the home audio use. In June 2008, we released automotive time domain speakers that provide a real surround system in a car by adapting the time domain theory cultivated through this home audio development. The new products are three surround speaker models (center speaker, satellite speaker and tune-up subwoofer). Each of them is equipped with our unique technologies such as a ground anchor, a floating structure, and a R2R structure, and the sounds produced by these products are more excellent than ever in spatial reproduction. This paper explains the development background of the automotive time domain speakers and our unique technology to achieve them. Then it goes on to explain our challenges for the automotive system. 26
