Scuba diving voice and communication system using bone conducted sound
First Claim
1. 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.

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.
