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.
