FIELD: methods and devices meant for correction of output signal of acoustic transformer during alteration of its acoustic impedance, for example, transformer with ear clamp in wireless communication devices.
SUBSTANCE: in accordance to the invention, during correction of sound signal alteration is measured in electrical parameter, at least on one frequency, which is changed with alterations in acoustic impedance of acoustic transformer. On basis of measured values, dynamic corrections are introduced to sound signal injected into acoustic transformer. Additionally a device is suggested for realization of correction of output signal of acoustic transformer.
EFFECT: increased efficiency.
