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 19):
Electronic offset compensation circuit as claimed in  claim 18 , which electronic offset compensation circuit is furthermore designed to\n a) calculate a velocity of the membrane based on an input voltage U in  and an input current I in  to a coil of the transducer and based on an idle driving force factor of the transducer in an idle position of the membrane; b) calculate a position of the membrane by integrating said velocity; c) calculate the velocity of the membrane based on the input voltage U in  and the input current I in  to the coil of the transducer and based on a driving force factor of the transducer at the position of the membrane calculated in step b) and to d) recursively repeat steps b) and c).
