Crosstalk elimination method and system of bone conduction earphone

The invention relates to a crosstalk elimination method and system of a bone conduction earphone. The method comprises the following steps: acquiring a bone conduction transfer matrix when a user wears the bone conduction earphone; acquiring a stop-band frequency range of a form factor; obtaining a filtered approximate crosstalk elimination matrix; performing crosstalk elimination on binaural signals input into the bone conduction earphone by using the approximate crosstalk elimination matrix; obtaining a crosstalk-eliminated sound signal; playing the crosstalk-eliminated sound signal to obtain a sound signal heard by both ears of the user; determining a final crosstalk elimination matrix according to the bone conduction transfer matrix, the approximate crosstalk elimination matrix and thesound signal heard by the two ears of the user; and performing crosstalk elimination on the binaural signals input into the bone conduction earphone according to the final crosstalk elimination matrix. According to the bone
