Abstract
The present application relates to a method and apparatus for eliminating sound leakage which includes: determining a first frequency response curve of a first sound wave generated by the call voice at a first position outside a terminal device; controlling a vibration motor to drive a rear housing of the terminal device to vibrate to generate a second sound wave; determining a second frequency response curve of the second sound wave at the first position; and regulating the second frequency response curve to a third frequency response curve, frequency response of the third frequency response curve being superimposed on and canceling frequency response of the first frequency response curve at a corresponding frequency. The vibration motor drives the rear housing to vibrate to actively generate the second sound wave superimposed on and canceling the first sound wave generated by call sound leakage, so as to eliminate leakage of call content.
