Abstract
In a communication device ( ) with an earpiece ( ) and a microphone ( ), there is a sensor ( ) relating a first connection line ( ) from the earpiece ( ) to the microphone ( ) on a system ( ) which is independent of the device and of the person using it, such as the earth's gravitational field, and which selects the operating mode QUIET ( ) or LOUD ( ) of the communication device in accordance with this. The sensor ( ) switches the communication device ( ) to QUIET when the angle ( ) between the connecting line ( ) and the plumbline ( ) of the gravitational field basically corresponds to the angle ( ) between a second connecting line between the ear ( ) and the mouth ( ) of a person ( ) who is authorized to make the call, so as to bar other persons ( ) who are in the vicinity (X ) from hearing the output from the communication device loudspeaker ( ).
