Abstract
Embodiments of the invention disclose a bone-conduction sound transmission device and method. The device comprises a signal output module for providing a digital audio signal, a signal conversion and emission module for converting the digital audio signal into a vibration signal and emitting the vibration signal, a signal detection module, for detecting the vibration signal for at least one position in the transmission path from the signal conversion and emission module to a receiving end, and a signal feedback module which is configured to calculate an attenuation coefficient of the vibration signal at each of the positions, determine a compensation signal based on the attenuation coefficient and compensate for the vibration signal generated from the signal conversion and emission module with the compensation signal.
