A scuba diving mouthpiece for supplying air to a diver, said mouthpiece attachable to a source of air, said mouthpiece comprising:

• a mouth engageable body including at least one biteplate, each said biteplate adapted for being disposed between and engageable by the teeth of the diver;
• a sound transducer associated with said body, said sound transducer including a magnetostrictive element with opposing ends, said magnetostrictive element being expandable and contractible in an axial direction in a presence of a magnetic field;
• and
• a sound conducting member including a movable distal end and an opposing fixed end, said sound conducting member being operatively connected with one of said ends of said magnetostrictive element at a location between said distal end and said fixed end, said sound conducting member being embedded within said body and configured to receive audio sounds from said connected sound transducer, said sound conducting member also being configured to transmit audio sounds through at least one said biteplate, whereby said audio sounds may be conducted to the teeth of the diver.
