The invention relates to an earphone () with leakage control, which can be switched between states with and without leakage to adapt the earphone to different listening situations. The leakage of the earphone may be enabled and disabled automatically in dependence of the sound source and/or may be controlled manually by the user. The earphone is connectable to a device and comprises: a housing () substantially covering the external auditory meatus, and accommodating a loudspeaker element (); the housing further comprising a channel () extending between an inner end () facing the external auditory meatus, and an outer end () facing the environment; and closure means () being switchable between a closed state in which said channel is substantially closed, and an open state in which said channel is admitting sound from the environment. The invention also relates to a device co-operating therewith, such as a mobile telephone.

Earphone with controllable leakage of surrounding sound and device therefor

An electroacoustic device includes a rear body portion containing electronic circuits, being so dimensioned and shaped as to be carried by a human user behind the user's ear and having an upper end portion and a frontal body portion with an upper end portion connected to the upper end portion of the rear body portion. The device may include an electroacoustic speaker transducer connected to the frontal body portion and arrangeable in a sound transmitting relationship to the user's ear canal when the device is carried by the human user. The speaker transducer may be rotatable about an axis which is arranged on a plane that is substantially parallel to the side of the head of the user when the device is carried by the human user.
