USER TERMINAL AND METHOD FOR REMOVING LEAKAGE SOUND SIGNAL USING THE SAME

摘要

Disclosed is a user terminal device providing a voice call function. The user terminal device comprises the following parts: a voice signal output part outputting a voice signal to the user of the user terminal device; a control signal generating part generating a control signal for removing a leaked voice signal which is generated when the voice signal outputted through the voice signal output part is leaked around the user; and a control signal output part outputting the generated control signal. The control signal has a reversed phase with respect to the leaked voice signal at a target point in order to minimize the size of the leaked voice signal delivered to the target point which is separated from the user terminal device by a predetermined distance.
