Abstract: The invention relates to a device for listening to voice and/or musical signals by means of cranial bone transmission, comprising a case (8, 15) having a forward frontal face, which is sealed by a flexible membrane (11), and a rear frontal face (15a), which consists of a rigid, hermetic wall, and comprising a piezoelectric element (1) having suitable dimensions in order for same to be integrated in the case, means (18) for supporting the piezoelectric element which are suitable for joining the periphery of the latter to the case in a solid manner, in such a way as to divide the internal volume of the said case into two hermetic chambers: a forward chamber (6) filled with an incompressible gel or fluid, and a rear chamber (7) comprising damping means (28) suitable for compensating the stresses exerted on the piezoelectric element (1) which result from the forces exerted on the flexible membrane (11).
