AES E-Library: Optical Measurement of Loudspeaker Driver Large Signal Displacement Parameters by Weaver, John E.; Leach, W. Marshall
Optical Measurement of Loudspeaker Driver Large Signal Displacement Parameters |
An optical technique for measurement of the peak-to-peak large signal displacement of a loudspeaker driver cone under dynamic operating conditions is presented. The method allows the identification and measurement of shift in the cone zero center position as functions of drive level and frequency. It is believed that these shifts are caused by nonlinearities in the cone suspension. |
