Abstract
A hearing device or another hearing apparatus is to be made smaller in terms of its dimensions. It is proposed for this purpose to develop a battery contact at least in one section as an induction coil. The current produced by the battery can thus compensate for an interference field of a telephone coil, said interference field being produced for example by a hearing device earpiece, and no separate coils need to be provided.
Claims20
A battery contact apparatus for a hearing apparatus, comprising:
- a first contact that contacts a first pole of a battery;
- and
- a second contact that contacts a second pole of the battery and comprises an induction coil,
- wherein the induction coil conducts all of a current generated by the battery, and wherein a structural and a positional arrangement of the induction coil relative to circuitry of the hearing device is configured so that an electromagnetic field generated by the induction coil is effective to compensate for an electromagnetic interference field generated by the circuitry of the hearing device.
A power supply system for a hearing apparatus, comprising:
- a battery with a first pole and a second pole;
- a first contact that contacts the first pole of the battery;
- and
- a second contact that contacts the second pole of the battery,
- wherein the second contact is disposed on a turn of an induction coil that discharges a current generated by the battery, wherein a structural and a positional arrangement of the induction coil relative to an electromagnetic earpiece of the hearing device is configured so that an electromagnetic field generated by the induction coil is effective to compensate for an electromagnetic interference field generated by the electromagnetic earpiece.
A hearing apparatus subject to an electromagnetic interference field, comprising:
- a battery;
- circuitry powered by the battery;
- a contact touching the battery and supplying current generated by the battery to the circuitry;
- wherein the contact comprises a dual functioning induction coil;
- and
- wherein the induction coil touches the battery at an exterior surface of the coil remote from an end of the coil to create a current flow from the battery to the circuitry and to generate an electromagnetic field, wherein a structural and a positional arrangement of the induction coil relative to the circuitry is configured so that the electromagnetic field generated by the induction coil is effective to compensate for the electromagnetic interference field generated by the circuitry of the hearing device.
