Measuring Speaker Excursion
Speaker Excursion Test Youtube A method for designing a loudspeaker excursion estimator comprises measuring an excursion related parameter for a loudspeaker, for each of a plurality of loudspeaker input signal levels. Edwin demonstrates the difference between x max and excursion of a woofer. using a laser to measure excursion. perhaps some triangle geometry should be used for a more accurate figure.
Excursion Speaker Installations Speakerinstallationphotos Xmax represents the maximum linear excursion of a subwoofer driver, measured as the distance the voice coil can travel while maintaining linear motor force. this critical specification directly impacts power handling, distortion levels, and overall performance capabilities. On the contrary, the most up to date instruments for distortion analysis can measure the variations in loudspeaker parameters when they are fed with high level signals. in this way, an excursion limit can be fixed beyond which the parameter’s variation becomes excessive. Speaker xmax is the maximum linear excursion (or displacement) of a speaker’s voice coil within the magnetic gap of the speaker. it is important to never exceed this distance, as doing so can create undesirable frequency output, such as distortion. Xmax (maximum linear excursion) represents the maximum linear travel of a speaker’s voice coil — that is, how far the diaphragm can move forward and backward while staying within the magnetic field’s linear region.

Hi team, i used the learning board to model a speaker and got below excursion vs frequency curve. i have two questions about this curve. 1. what does mm v stands for? v stands for peak value or rms value? 2. assume that a single tone signal drives the speaker. if frequency equals f1, then the speaker excursion will be e1. Excursion is all about how much a woofer (or any speaker driver really) is moving. a woofer produces sound by moving the cone back and forth. the range of that motion is the excursion (usually measured in mm). peak to peak is the convention used as opposed to one way travel. If you keep driver excursion within xmax, there will always be the same height of voice coil within the gap. the diagrams below show the maximum excursion in each direction to keep within mathematically calculated xmax. You need a true position sensor of some sort. hall sensor can work with the sensor axis placed orthogonal to speaker axis and a small neodymium rod sliding along, on axis. transfer is nonlinear but can be linearized by measurement. i've seen concepts using foil based strain gauges.
