Mouthpiece and speaker assemblies for underwater speech using SCUBA and snorkel equipment, which mouthpiece is characterized by a molded rubber or plastic mouthpiece having a regulator or snorkel connector, a lip cup and a pair of elongated, serpentine or curved teeth grips or bites extending from the lip cup for gripping by the jaw teeth of a SCUBA diver or snorkeler and facilitating movement of the lips to enable underwater speech. The mouthpiece is designed for attachment directly to an underwater speaker, a snorkel, a snorkel and speaker combination, or to the mouthpiece of a conventional second-stage regulator and speaker combination. The underwater speaker includes a pair of flexible membranes connected at a common perimeter and designed to pulse and flex responsive to the pressure pulses of a diver or snorkeler's breath and voice. |
