Title:
SOUND LEAKAGE ELIMINATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/050950
Kind Code:
A1
Abstract:
The present application relates to the field of terminal devices, and in particular to a sound leakage elimination method and apparatus. A sound leakage elimination method, comprising: when it is detected that a receiver outputs a call voice, controlling a collection device to determine a first frequency response curve, at a first position outside a terminal device, of a first sound wave generated by the call voice; controlling a vibration motor to drive a rear housing of the terminal device to vibrate to generate a second sound wave; determining, by means of the collection device, a second frequency response curve of the second sound wave at the first position; and according to the first frequency response curve, adjusting, to a third frequency response curve, the second frequency response curve generated by the second sound wave at the first position, wherein the frequency response of the third frequency response curve is used for superimposing and eliminating the frequency response of the first frequency response curve on a corresponding frequency. By means of the embodiments of the present invention, a vibration motor drives a rear housing of a terminal device to vibrate, so as to actively send a second sound wave, and the second sound wave superimposes and eliminates a first sound wave generated by leaked call sound, so as to eliminate the problem of leakage of call content.
