<p>The present invention is intended as a method for producing an electromagnetic transducer of variable reluctance type, where the transducer's seismic mass side and load side are mounted together in a first step while the inner and/or outer air gaps are supplied with shims in order to create balanced air gaps in an axial direction between the bobbin core's arms and the inner and outer yokes, whereupon in a second step the bobbin core is fixed through the side piece to an adapter already attached in a corresponding free moving end of a spring suspension, with compliant properties working in an axial direction and arranged between the seismic mass side and the load side in resting state in order to maintain balanced air gaps when finally, in a third step, the shims are removed and the air gaps are released.</p> |
