T14 - Loudspeaker Design Part 2: Horn Drivers—History, Theory, and Technology—A Master Class
Presenter:Alexander Voishvillo, JBL/Harman Professional - Northridge, CA, USA
Abstract:
Horn drivers are the oldest "electrical" transducers and their invention preceded the development of the direct-radiating loudspeaker. Historically, several major inventions in the late 1800s and early 1900s triggered the invention and development of horn drivers; it was the invention of the telephone, radio, phonograph, and triode. Principles of operation for the compression driver, based on matching the output mechanical impedance of the vibrating diaphragm and the loading impedance of the phasing plug and horn, were understood since the beginning of the 1900s. The motors of the early compression drivers were based on a moving armature rather than on a moving coil.
