T17 - Almost Everything You Ever Wanted to Know About Loudspeaker Design
Presenter:Christopher Struck, CJS Labs - San Francisco, CA, USA; Acoustical Society of America
This tutorial will walk the audience through an entire loudspeaker design as well as introducing the basic concepts of loudspeakers. Equivalent circuits, impedance and Thiele-Small Parameters are shown. Inherent driver nonlinearities are explained. The effects of modal behavior and cone breakup are demonstrated. Closed Box and Ported Box systems are analyzed and several design examples are meticulously worked through, both with hand calculations and using CAD. Issues with multiple drivers and cabinet construction are discussed. Directivity and diffraction effects are illustrated. Crossover network design fundamentals are presented, with a specific design example for the previously shown ported enclosure design.
This session is presented in association with the AES Technical Committee on Loudspeakers and Headphones |
