Abstract The phenomena of bifurcation, chaos and hysteresis of electrodynamic cone loudspeaker have been investegated experimentally in mid-frequency range. The frequency spectrum, as well as the phase diagram in frequency-voltage phane, of bifurcation and chaos is given. The hysteresis phenomenon is observed clearly from frequency response curve.
