ABSTRACT:
A device is provided for earphones that are introduced into the auditory canal that provide protection against cerumen in which the sound from the earphone is conducted onto a membrane that is arranged essentially parallel to the auditory canal. Proceeding from the membrane, the sound is forwarded onto the tympanum, where the membrane at least partially seals the earphone so that cerumen is kept away from the earphone. The membrane, including the earphone, can be removed from the hearing aid housing for cleaning purposes.
