Abstract

The invention relates to a noise cancelling control method and a relevant device. The method comprises the following steps: the target scene type of a current scene is identified through media equipment; a target noise cancelling algorithm matching the target scene type is determined according to a preset corresponding relation; a noise cancelling control instruction is generated according to the target noise cancelling algorithm; and the noise cancelling control instruction is sent to a headphone connected with the media equipment. Thus, the headphone can be switched to the noise cancelling algorithm matching the current scene through the noise cancelling control instruction, and the noise cancelling effect of the headphone can achieve the best under the current scene. Compared with the existing noise cancelling headphone which cancels noise according to a fixed noise cancelling algorithm, in the embodiment of the invention, the headphone can be switched to different noise cancelling algorithms according to different application scenes, so that the noise cancelling demands under different application scenes are satisfied, and an optimal noise cancelling effect is achieved.

Description

technical field [0001] The present invention relates to the technical field of terminal equipment, in particular to a noise reduction control method and a related device. Background technique [0002] At present, most media devices, such as mobile phones and tablet computers, are equipped with earphones, so that users can enjoy media files such as video and audio without affecting other people around them. When the user is in a noisy environment, even if the user wears earphones, he will be disturbed by the environmental noise. [0003] In the related art, a noise reduction control module is built into the earphone, and the noise reduction control module executes a preset noise reduction algorithm to reduce or even eliminate the interference of the environmental noise to the earphone user. For example, in the existing Active Noise Cancellation (Automatic Noise Canceller, ANC) earphones, the noise cancellation control module generates sound waves with the opposite phase and ...
