[origin: EP1480492A2] The transmission coil system has first and second transmission coils (3,5) and a coil core (7). The first coil (3) can be connected to a stimulation unit. The second coil (5) can be used as part of a resonant stimulatable circuit and both transmission coils are wound next to each other on the core so that both coils are loosely magnetically coupled to each other. An independent claim is also included for the following: (a) a remote controller for a hearing aid.
