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.

Abstract: A method for eliminating sound leakage includes: controlling, upon detecting call voice being outputted by a receiver, a collection device to determine a first frequency response curve of first sound wave of the call voice at a first position outside a terminal device; controlling a speaker to generate a second sound wave; controlling the collection device to determine a second frequency response curve of the second sound wave at the first position; and regulating, according to the first frequency response curve, the second frequency response curve to a third frequency response curve. Frequency responses of the first and third frequency response curves at a corresponding frequency are superimposed on and cancel each other. The speaker actively generates second sound wave that is modulated according to a parameter of first sound wave, so as to ensure that second sound wave effectively eliminates leakage of call content caused by first sound wave.
