The invention discloses an audio
processing method for a
bone conduction headset, the
bone conduction headset and an audio playback device based on the
bone conduction headset. The bone conduction headset comprises a
human bone and
tissue model modeling module, a digital pre-corrector, a
delay estimation unit, a digital-to-analog converter, an analog-
digital converter, a first low-pass filter, a second low-pass filter, an audio
amplifier, an audio driving
amplifier, at least one bone conduction
microphone, and at least one bone conduction vibrator. In the method,
human bone and tissue attenuation effect information of different users is detected in real time; a compensating
transfer function is generated based on the attenuation effect information; and an input
audio signal is subjected to digital pre-correction via the compensating
transfer function, and then the processed input
audio signal is transmitted in human bones and tissues. Through adoption of the method, a problem that experience of the bone conduction headset is different caused by different
tissue thickness of the different users is solved.
