Abstract (en)

The present invention relates to a method for driving an electrodynamic vibration device for outputting a vibration signal with a predetermined vibration strength for a mobile telecommunication means, whereby the electrodynamic vibration device is driven by an alternating current driving signal. The driving signal comprises time successive sinewave signals of varying periods, whereby the variation of the periods is set so, that the duration of each alternating current signal with constant period is shorter than 25 ms. Further, the present invention relates to a driving means (2) for driving an electrodynamic vibration device for outputting a vibration signal with a predetermined vibration strength for a mobile telecommunication means for carrying out this method. <IMAGE>
