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).
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 device as claimed in one of the preceding claims, in which the piezoelectric membrane comprises a piezoelectric disk (4) fixed to a flexible support disk (3), wherein the peripheral weight forms the peripheral edge, fixed to said membrane, of a hollow casing (6) which isolates the piezoelectric disk (4) and which has a suitable shape for permitting the vibrations of the piezoelectric membrane (3, 4).
