METHOD AND DEVICE FOR GENERATING ELECTROMECHANICAL CONVERSION SIGNAL Russian patent published in 2004 - IPC

FIELD: acoustic engineering; direct and inverse electromechanical conversion including detection of induction converter operation error. SUBSTANCE: proposed method that can be used for sound reproduction with aid of dynamic loudspeaker and recording on magnetic medium includes generation of initial electric signal reflecting conversion process and incorporating associated parasitic signals dependent of electromechanical conversion parameters involving at least one addition of signals obtained. Parasitic signals are produced along with generation of signal reflecting electromechanical conversion process; they depend on electromechanical conversion parameters and each of them is independently corrected by varying its amplitude-frequency or phase-frequency parameters for next addition to conversion signal and for producing signal free from parasitic signals. Device implementing this method incorporates provision for eliminating impact of conversion parameters due to design features of electromechanical converter causing degradation of amplitude-frequency and phase-frequency characteristics of electromechanical conversion. EFFECT: improved quality of conversion. 7 cl, 2 dwg
