Abstract: A bone conduction hearing aid system for generating bone conduction vibrations is disclosed. The bone conduction hearing aid system has a hearing aid with a vibrator. The hearing aid system includes an interconnection unit to connect the hearing aid to the user. There is a coupling between the interconnection unit and the hearing aid to connect and disconnect the hearing aid to and from the interconnection unit. The interconnection unit has connection portion and contact plate portion. The connection portion and the contact plate portion are designed in one integral piece of continuous polymer material. The interconnection unit has a concave or planar adhesive surface that can be adhered to the skin on the head of the user without applying any specific pressure against the skin. The sound vibrations are transmitted from the vibrator to the hearing organ as bone conduction sound vibrations.

Abstract: The hearing device system has features for preventing a hearing device from falling off from the user. The hearing device system has a safety line has a first portion connected to the hearing device and a second portion connected to an interconnection unit attached to the user. There is a coupling between the interconnection unit and the safety line that enables the user to connect and disconnect the safety line to and from the interconnection unit. The interconnection unit has an adhesive surface facing the skin so that it can be adhered to the skin of the user.
