Abstract
Abstract A portable communication device has an apparatus housing with a movable element attached thereto and a sensor for detecting a position of the movable element in relation to the apparatus housing. The communication device also has an electrodynamic device having a magnet. The sensor is arranged to detect the magnetic field originating from the magnet in the electrodynamic device and to provide an output which is relative to the apparatus housing. A device is provided, in the movable element, for conducting the magnetic field from the electrodynamic device to the sensor.
