Patent ID: 8750945

Claim:
A phone device for “hands-free” interfacing with a portable phone, said device ( 10 ) being in the form of a single-piece accessory adapted to be removably fastened by being clamped onto a planar equipment of an automotive vehicle, in particular a sun visor, said device comprising a casing ( 12 ) accommodating: a sound pick-up microphone sensor ( 14 ); a sound reproduction transducer ( 54 , 16 ); a plurality of control buttons ( 18 , 20 , 22 , 24 ); a printed board ( 64 ) carrying electronic circuits; and a power battery; as well as, possibly, operation indicators ( 26 , 28 ), an external connector and a near-field communication antenna ( 66 ), wherein the casing is in the form of an elongated band bended on itself in such a manner to form a clamp having laterally a U-shaped profile, with a first branch ( 32 ) and a second branch ( 34 ) extending respectively on either side of a central region of greater curvature of the U ( 30 ), said device being characterized in that: the bended band has in the central region a transverse discontinuity ( 36 ) mechanically separating the two branches; and the transducer is carried by the first branch and the sensor is carried by the second branch, so that the transducer and the sensor are acoustically decoupled between each other by said transverse discontinuity.
