Abstract: A device forming a mouthpiece for a snorkel or diving regulator, adapted to fit in the mouth of a diver or swimming and comprising a body provided with an air intake and extended by two lateral branched each provided with a bite tab, and at least one transducer buzzer positioned in one of the branches and comprising a piezoelectric membrane. Each transducer buzzer comprises a peripheral weight fixed to the periphery of the piezoelectric membrane, and elements for transmitting the vibrations of the membrane towards the teeth of the diver or swimmer. Furthermore, each transducer buzzer is positioned in the branch in such a way that the piezoelectric membrane is totally isolated from the external environment, and that the transmission elements form a contact interface with the teeth at the bite tab.

Abstract: The invention relates to a device forming a mouthpiece for a snorkel or diving regulator, adapted to fit in the mouth of a diver or swimmer and comprising a body (20) provided with an air intake and extended by two lateral branches (21) each provided with a bite tab (22), and at least one transducer buzzer positioned in one of the branches (21) and comprising a piezoelectric membrane (3, 4). According to the invention, each transducer buzzer comprises a peripheral weight (6) fixed to the periphery of the piezoelectric membrane (3, 4), and means (5, 30) for transmitting the vibrations of said membrane towards the teeth of the diver or swimmer. Furthermore, each transducer buzzer is positioned in the branch (21) in such a way that the piezoelectric membrane (3, 4) is totally isolated from the external environment, and that the transmission means (5, 30) form a contact interface with the teeth at the bite tab (22).
