AES Rome 2013
Saturday, May 4, 19:00 — 20:00 (Auditorium Loyola)
Wolfgang Klippel, Klippel GmbH - Dresden, Germany
The Richard C. Heyser distinguished lecturer for the 134th AES Convention is Wolfgang Klippel. The title of his lecture is, "Small, Loud-Speakers: Taking Physics to the Limit." Klippel’s title plays on the challenge of engineering small loudspeakers that can also be loud, have high efficiency and low distortion. While the basic construction and principle of the moving coil loudspeaker has remained unchanged for a century, our understanding of its operation and limitations has increased very considerably. Modern signal processing techniques, coupled with careful design of the magnet, voice coil and suspension, can be employed to create small drive units that have an optimum trade-off between the crucial design factors. An understanding of the perceptual effects that arise from these design trade-offs helps to bring about loudspeakers that not only measure well but sound good. This is particularly important as compact devices such as mobile phones demand more and more quality from tiny loudspeakers in minimal enclosures.
