摘要： The device (1) comprises: a casing (2-4) in which there is clamped a diaphragm (5) which, together with a portion of the casing (2-4), defines at least one chamber (6, 7) having a variable volume; a winding (14); an interaction member (13), adapted to magnetically interact with the winding (14) as a consequence of a displacement of the diaphragm (5), in such a way that the inductance of the winding (14) varies as a function of the relative position of the interaction member (13) with respect to the winding (14), and a processing unit (17) coupled to the winding (14), in order to supply electric signals having a parameter which is variable as a function of the inductance of the winding (14) and thus as a function of the relative position of the interaction member (13). The processing unit (17) comprises memory means (22) adapted to store data representative of correction values which, when applied during operation to the instantaneous actual values of the parameter, allow corrected values of the parameter, corresponding to a predetermined transduction characteristic, to be obtained. The processing unit (17) is designed to correct the instantaneous actual values of the parameter in such a way that, at least when the actual values of the parameter are lower than a predetermined value, the processing unit (17) generates and emits corrected values of the parameter which are amplified by a predetermined factor.
