An earphone facility is proposed to reduce feedback in hearing devices with an external earphone. The earphone facility includes an earphone, which is embodied to convert electrical signals, and an earpiece, which lies snugly against the auditory canal when the earphone facility is being worn. A stem is attached to the earphone, having a smaller circumference than the smallest circumference of the earphone. Also a support element is disposed between the stem and an internal wall of the earpiece, said support element holding the stem in the earpiece in a movable manner. With this structure vibrations of the earphone are barely transmitted to the earpiece so that feedback is ultimately reduced. |
