Abstract:
A method for avoiding an offset of a membrane ( 3 ) of an electrodynamic acoustic transducer ( 1 ) having two voice coils ( 7, 8 ) is presented, wherein a control voltage (U CTRL ) is applied to at least one of the voice coils ( 7, 8 ) until the electromotive force (U emf1 ) of the first coil ( 7 ) or a parameter derived thereof and the electromotive force (U emf2 ) of the second coil ( 8 ) or a parameter derived thereof substantially reach a predetermined relation. Furthermore, an electronic offset compensation circuit ( 12 ) is presented, which performs the above application of a control voltage (U CTRL ). Finally, the invention relates to a transducer system with a transducer ( 1 ) and an electronic offset compensation circuit ( 12 ) connected to the transducer ( 1 ).

Claim (Index 11):
Method as claimed in  claim 10 , characterized in that the velocity, the input voltage U in , the input current I in , the idle driving force factor, the driving force factor and the position are related to the same point in time.
