1. Description
This horn loudspeaker can be used to approximate
a point source of sound and is better suited for
acoustic experiments than large conventional box
loudspeakers. For excitation of a Kundt tube, the
outlet of the speaker can be directly placed at the
end of the tube. For the Chladni patterns, it can be
positioned under the Chladni plate.
The dynamic excitation system of the speaker has
thermal excess current protection.
