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.

A snorkel for enabling vocal communication under water comprising:
- a hollow body;
- a breathing tube, adapted to extend above the surface of water, coupled to said hollow body;
- mouthpiece means coupled to said hollow body and adapted to be held by the mouth of a snorkeler;
- flexible means in said mouthpiece means for enabling articulation of sounds by the lips of said snorkeler;
- and
- diaphragm means in said hollow body tuned in the range of 1500 to 3000 Hertz, in water, for augmenting coupled sound from said hollow body to the water.
A snorkel for enabling underwater vocal communication comprising:
- a hollow body;
- a breather tube, adapted to extend above the surface of water, coupled to said hollow body;
- mouthpiece means, including a passageway having a pair of flexible lips adapted to be closed by the lips of a snorkeler for articulating plosive and other sounds, coupled to said hollow body;
- and
- diaphragm means, tuned to resonate in the range of 1500 to 3000 Hertz, in water, secured to said hollow body for augmenting the sound coupled from said hollow body to said water.
Mouthpiece means, including a passageway for enhancing underwater vocal communications, comprising:
- a pair of flexible lips in said passageway for enabling articulation of plosive sounds therein;
- and
- a readily collapsible bubble formed in a surface of said passageway engaged by the lower lip of a person.
