Lyapunov Exponents and General Dimensions of Strange Attractor of Electrodynamic Cone Loudspeaker

Lyapunov exponents, Lyapunov dimension and general dimensions have been determined from a time series of electrodynamic cone loudspeaker. It is found that a low-dimensional chaotic at tractor has one positive largest exponent, and the Lyapunov dimension is in concordance with the Hausdorff dimension which calculated by general correlation integrated method.
