Tube- or vessel-kazoos
The sound is excited by a tightly stretched membrane made to vibrate by speaking or singing into it; the sound of the membrane modifies that of the voice. The membrane is placed on top of a tube or box. Africa; while also, E. Asian flutes with a lateral hole sealed by a membrane, exhibit an affinity with the principle of the tube kazoo.
