Title: BONE CONDUCTION SOUND TRANSMISSION DEVICE AND METHOD
Abstract:
Disclosed in embodiments of the present invention are a bone conduction sound transmission device and method. The bone conduction sound transmission device comprises: a signal output module for providing a digital audio signal; a signal conversion and transmission module for converting the digital audio signal to a vibration signal and transmitting the vibration signal; a signal detection module for detecting the vibration signal of at least one position in a transmission path from the signal conversion and transmission module to a receiver end; and a signal feedback module for calculating an attenuation coefficient of the vibration signal of each of the positions, determining a compensation signal according to the attenuation coefficient and compensating the vibration signal generated by the signal conversion and transmission module using the compensation signal. The embodiment of the present invention precisely compensates the sound signal attenuation in the process of bone conduction, thus improving amplitude-frequency response characteristics of a sound signal and distortion of the sound signal in the process of bone conduction, and enabling better sound quality heard by a user.
