T1 - Loudspeaker Design, Part 1: Almost Everything You Ever Wanted to Know About Loudspeaker Design —A Master Class
Presenter:Christopher Struck, CJS Labs - San Francisco, CA, USA
Abstract:
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. Passive Radiator, Band Pass, and Transmission Line systems are also shown. 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. A brief overview of room acoustic effects on loudspeakers is also presented.
This session is presented in association with the AES Technical Committee on Loudspeakers and Headphones |
