Embodiment Construction

[0051] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0052] In this part, concepts involved in each embodiment are described first.

[0053] The microphone control method in the embodiment of the present invention can be applied to mobile terminals such as mobile phones, PADs or notebook computers, where the mobile terminal has multiple microphones (ie microphone groups), or the mobile terminal supports earphones with multiple microphones. In the embodiment of the present invention, when the main mi...

Abstract

The embodiment of the invention discloses a microphone control method comprising the steps that when an application requiring to collecting sound is started, a microphone group is triggered to collect sound signals, and the microphone group includes at least two microphones; the sound signals collected by the main microphone of the microphone group are processed so that signal intensity is acquired; whether signal intensity is less than a first preset threshold is judged; and other microphones of the microphone group act as the main microphones if the judgment result is yes. Correspondingly, the embodiment of the invention also discloses a microphone control device. With application of the microphone control method and device, the sound signals collected by the auxiliary microphones act as voice input signals under the condition of failure of the main microphone so that voice sound quality can be enhanced.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a microphone control method and device. Background technique [0002] Existing mobile terminals, such as mobile phones, PADs, notebook computers, etc., are usually provided with multiple microphones, including a main microphone and an auxiliary microphone. The volume of background noise collected by the main microphone and the auxiliary microphone is basically the same, while the collected user voice There will be a volume difference of about 6dB. Therefore, after the sound signal collected by the auxiliary microphone is obtained, a compensation signal is generated by decoding to perform noise processing on the sound signal picked up by the main microphone. When the user is talking or recording, if the main microphone is damaged, or the main microphone is blocked due to the different placement of the mobile terminal, in this case, if the sound signal collected by...
