Abstract
A hearing apparatus is to be provided, with which the battery can be exchanged in an almost wear-free fashion. Provision is thus made to magnetically attach a battery compartment or a battery holding device in the housing of the hearing apparatus or hearing device. The battery holding device is inserted into an opening in the housing. A detachable magnetic connection realized by magnetic elements thus exists between the housing and the battery holding device, the principle force component of which runs in the insertion direction. It is thus possible to dispense with plug or snap connections for instance.
