A structure for installing a bone conduction device on eyeglasses, which enables the bone conduction device, used for a communication apparatus or an acoustic apparatus, to be installed on a temple of the eyeglasses or on the end of the temple. The device can be easily installed independent of the shape of the temple without giving awkward feeling to the wearer. The structure is made up of a bushing (1) fitted on the temple (11) of the eyeglasses or on the end (12) of the temple and of a helical torsion spring (2) wound around the bushing (1). The bone conduction device (3) is attached to one end of the helical torsion spring (2) and a pad (4) is attached to the other end of the helical torsion spring (2). In use, the bone conduction device (3) and the pad (4) are urged to the face side by the torsion coil spring (2).

La présente invention concerne une structure de fixation d'un dispositif de conduction osseuse sur des lunettes, permettant au dispositif de conduction osseuse, utilisé pour un appareil de communication ou un appareil acoustique, d'être fixé sur une branche de lunettes ou sur l'extrémité de la branche. Le dispositif peut facilement être fixé indépendamment de la forme de la branche sans donner de sensation désagréable à celui qui le porte. La structure comprend une bague (1) ajustée sur la branche (11) des lunettes ou sur l'extrémité (12) de la branche et un ressort à torsion hélicoïdal (2) enroulé autour de la bague (1). Le dispositif de conduction osseuse (3) est fixé à une extrémité du ressort à torsion hélicoïdal (2) et un coussinet (4) est fixé à l'autre extrémité du ressort à torsion hélicoïdal (2). En mode de fonctionnement, le dispositif de conduction osseuse (3) et le coussinet (4) sont comprimés sur le côté du visage par le ressort à bobine de torsion (2).
