SYSTEMS AND METHODS FOR OBTAINING VIBRATION TRANSFER FUNCTION Russian patent published in 2023 - IPC H04R29/00 

FIELD: acoustics.

SUBSTANCE: invention relates to methods for measuring the transfer function. The method for obtaining the vibration transfer function contains the steps of: generating a first test audio signal and a second test audio signal by means of a test signal generation unit; generating, by means of an audio signal generating unit, a first audio signal and a second audio signal based on the first test audio signal and the second test audio signal, respectively; outputting, by the detector, a first feedback signal after receiving the first audio signal at the first location, the first feedback signal comprising a signal transmitted from the audio signal generating unit to the first location via a vibration transmission path and via an air conduction transmission path; outputting, by said at least one detector, a second feedback signal after receiving the second audio signal at a second location, wherein the second feedback signal comprises a signal transmitted from the audio signal generation unit to the second location via an air conduction transmission path; the vibration transfer function from the audio signal generating unit to the first location is determined by the feedback signal path determining unit based on the first test audio signal, the second test audio signal, the first feedback signal and the second feedback signal.

EFFECT: simple way to calculate the transfer function of vibration from bone conduction speakers to a microphone.
