Vibration and Radiation Analysis of Loudspeaker Cones
A new scanning technique for measuring the vibration and geometry of loudspeaker parts is presented. This data is the basis for numerical simulations using BEM and and FEA. A decomposition technique reveals radial and circular modes and the vibration component generating the acoustical output. New ways for loudspeaker diagnostics and cone optimization are illustrated on woofers, tweeters, headphones, and micro-speakers.
