ABSTRACT:
The invention is directed to a scuba diving mouthpiece for supplying air to a diver. The mouthpiece includes a mouth engageable body having at least one biteplate. Each biteplate is adapted for being disposed between and engaged by the teeth of the diver. A sound transducer is associated with the body, and includes a magnetostrictive element with opposing ends. The magnetostrictive element is expandable and contractible in an axial direction in a presence of a magnetic field. A sound conducting member includes a movable distal end and an opposing fixed end. The sound conducting member is operatively connected with one of the ends of the magnetostrictive element at a location between the distal end and the fixed end. The sound conducting member is embedded within the body and configured to receive audio sounds from the connected sound transducer. The sound conducting member is also configured to transmit audio sounds through at least one of the biteplates, whereby the audio sounds may be conducted to the teeth of the diver.
