Abstract (en)
A watchcase (1) has a support (9) at it's base for a microphone and loudspeaker transductor (22) mounted on a deformable membrane (17). The membrane has a rim (18) which is glued to the support (9) and the transductor (22) is held in position by elastic fittings (20). The transmission of vibrations from the transductor to the watchcase is blocked by a peripheral rim (40) on the deformable membrane.
