Air column resonance apparatus consists of two compact vertical plastic resonance tubes and sound source mini speaker.
【Overall Advantages to Users】
- The resonance tube has only half the length (480mm) of common ones (900~1000mm).
- Achieved compactness of the whole apparatus owing to the double-layered structure of the resonance tubes. The outer tube with scale works as a cylindrical water tank and the inner one works as a movable air column.
- The length of the air column is adjustable by raising or lowering the inner tube, which is easier than changing the length of the water column with a movable water reservoir.
