Abstract
A vocal communication snorkel includes a hollow body having a breather tube, adapted to extend above the water, coupled thereto and a mouthpiece adapted to be held by the lips of a snorkeler. The body has a pair of inwardly curved, spherically shaped diaphragms of thin plastic material that are tuned to resonance within the frequency band of 1500 to 3000 Hertz in water. The mouthpiece includes a passageway that is coupled to the body and a pair of flexible lips, that are closable by the lips of the snorkeler for articulating plosive sounds. A readily collapsible bubble, formed in the passageway and engageable by the lower lip of the snorkeler, facilitates closure of the passageway under pressure from the snorkeler's lower lip.
