Problems solved by technology

[0003] For electronic products with dual microphones, especially those that need to be worn, due to the different wearing parts of the user, the distance between the dual microphones and the user is different, and the fixed primary and secondary microphone settings will affect the sound quality
[0004] Taking a wearable device as an example, the user may wear it on the left or right hand. The fixed main and secondary microphone settings will make the main microphone far away when the user wears it on one hand, which will affect the sound quality.

Abstract

The invention discloses a switching method and device of double microphones. The method comprises steps of reading a switching parameter from a memory variable of a hardware abstract layer HAL, wherein the switching parameter indicates a main microphone and an auxiliary microphone in the double microphones; and calling a function of the HAL and configuring the switching parameter to the double microphones and corresponding coders and decoders through a Kernel layer. According to the invention, switching of the main microphone and the auxiliary microphone of the double microphones can be achieved, so a problem of reduction of sound reception quality caused by fixed setting of the main microphone and the auxiliary microphone is solved.

Description

technical field [0001] The invention relates to the field of microphones, in particular to a method and device for switching between two microphones. Background technique [0002] Microphones in electronic products are used for radio reception to realize functions such as calls and recordings. In order to improve the quality of sound reception, some electronic products are equipped with dual microphones, the main microphone is used to collect sound, and the auxiliary microphone is used for noise reduction. [0003] For electronic products with dual microphones, especially those that need to be worn, due to the different wearing parts of the user, the distance between the dual microphones and the user is different, and the fixed primary and secondary microphone settings will affect the sound quality. [0004] Taking a wearable device as an example, the user may wear it on the left or right hand. The fixed primary and secondary microphone settings will make the main microphon...
