Remote control for a hearing aid, and applicable hearing aid
First Claim
1. A remote control comprising a transmission unit operationally connected at its output to an inductive transmitter antenna, a control unit, the output thereof being operationally connected to an input of said transmission unit, and a a power supply powering said transmission unit and said control unit, wherein said transmitter antenna comprises a coil arrangement;
- said coil arrangement, said control unit said transmission unit and said power supply are integrated into a case of a wristwatch;
and said coil arrangement generates a magnetic field in response to said control unit at least approximately equal to a magnetic dipole with a dipole direction parallel to the case and in a direction of a wristband of said wristwatch as considered in a top view upon said case.

Abstract
A remote control of a hearing aid is integrated into a case (1) of a wrist watch with wristband (3). A coil antenna (5) of the remote control is designed to generate a field similar to that of a dipole (P) which substantially runs in the direction of the wristband (3). The wrist watch remote control for the hearing aid provides a reliable communication link that is assured for the in-situ hearing aid.
