Abstract
A mobile communications device (100) comprises a motion detector (101) for producing a signal which represents the kinetic state of the mobile communications device. Preferably the mobile communications device comprises a body and a vibrating alarm device in which a certain mass (105) is arranged so as to be movable with respect to the body of the mobile communications device, whereby said motion detector is an apparatus for measuring the movement of said mass. If the mass is arranged so as to rotate eccentrically with respect to a certain axle (103) and the vibrating alarm device further comprises an electric motor (102) with windings to rotate said axle, the apparatus for measuring the movement of said mass is an apparatus for measuring an electric current induced in the windings of the electric motor.
