Abstract

The invention provides a sound elimination method and a mobile terminal, which can solve the problem that the contents of a call are heard by other people due to too loud sound volume broadcast by a mobile phone receiver in some special call scenes. The method comprises the following steps: when a first sound output device of the mobile terminal broadcasts sound wave signals, obtaining sound wave signals to be processed acquired by a sound input device of the mobile terminal; obtaining a target sound wave signal to be processed from the sound wave signals to be processed, wherein the target sound wave signal to be processed and the sound wave signals broadcast by the first sound output device correspond to the same speech content; performing reversal processing for the target sound wave signal to be processed to obtain a reverse sound wave signal of the target sound wave signal to be processed; and broadcasting the reverse sound wave signal through a second sound output device of the mobile terminal to eliminate the sound wave signals that are broadcast by the first sound output device and have transmission distances greater than the preset threshold. Thereby, the privacy of users can be well protected, and the call experience of the users can be improved.

Description

technical field [0001] The present invention relates to the technical field of terminal design, in particular to a sound canceling method and a mobile terminal. Background technique [0002] At present, in some special call scenarios (such as formal occasions such as meetings or receiving private calls), the volume of the voice broadcast by the receiver of the mobile phone will be too loud, resulting in the content of the call being heard by others, resulting in poor user privacy. question of guarantee. [0003] The existing method is generally to actively lower the call volume, or find a place where no one is there to answer the call, but lowering the volume will also affect the user's own call experience, and it is troublesome and inconvenient to change the place to answer the call, thereby reducing the user's use experience. Contents of the invention [0004] The purpose of the present invention is to provide a sound cancellation method and a mobile terminal to solve ...
