Abstract: Increased interest has been witnessed over the past decades for techniques measuring the vibration of a loudspeaker membrane. In this proceeding, vision methods have been adapted to measure the displacement of the cones of low-frequency drivers. The movement of the membrane is recorded with industrial or consumer market high-speed cameras with frame rates greater than or equal to 240 fps. The measured displacement shows acceptable to very good agreement with the one measured by a laser vibrometer, depending on the camera model. The displacement of the membrane, coupled to the measured electrical impedance, can be used to retrieve the small signal parameters or some non-linear parameters of the speaker. Finally, the vision methods are used to retrieve the vibration patterns of the membrane.
