Chaotic State in an Electrodynamic Loudspeaker
An electrodynamic loudspeaker has been operated in a nonlinear regime when the k-factor strongly increases with displacements. For driving AC currents up to 2 A the vibration spectrum contains high frequency harmonics of the classic von Kármán type ; for currents in the range 2.6 to 4 A doubling of driving period appears ; and for currents in the range from 4 to 4.8 A multiple sequences of subharmonic vibrations begin with 1/4f and 3/4f. An application of currents higher than 4.8 A results in a white noise spectrum, which is a characteristic of chaotic state.
