DEVICE FOR AUDIO PLAYBACK BY TRANSDUCER, SYSTEM, METHOD (VERSIONS) AND COMPUTER PROGRAM Russian patent published in 2017 - IPC H04R3/04 

FIELD: physics.

SUBSTANCE: device for processing an audio signal by the sound transducer, comprises an equalization parameter determining unit for determining the equalization parameter set, and an equalizer adapted to equalize the input audio signal to produce the equalized audio signal. Determination of the equalizer parameters is performed depending on the image recognition, the identification signal evaluation, the impedance measuring sound transducer by frequency. Furthermore, the loading functionality and the unloading functionality are provided. The device is adapted to load the equalization parameter sets connected with one or more sound transducers, from the server, or using one or more equalization parameter sets connected with one or more sound transducers contained in the internal database. Herewith the database contains relationship between the reference impedance curves by frequency and the corresponding equalization parameter sets.

EFFECT: increasing the sound quality.
