Problems solved by technology

Although such a setting method is convenient, since the error of each electronic device 100 is not considered, there is no way to deal with the different errors of the gain of the first sound receiving module 110 and the second sound receiving module 112 in each electronic device 100. Therefore, the noise reduction effect of each electronic device 100 is different.

Abstract

The invention provides a calibration system built in an electronic device with noise reduction function. The calibration system includes: a first radio receiving module; a second radio receiving module; and a correction module. The correction module is used to correct an adjustment value of the first sound receiving module and the second sound receiving module, wherein the adjustment value is used to gain the sound collection results of the first sound receiving module and the second sound receiving module.

Description

technical field [0001] The invention relates to a method for dealing with component errors, in particular to a method capable of correcting errors of multiple sound-receiving modules to reduce noise. Background technique [0002] Due to the continuous reduction in weight and miniaturization of electronic devices, mobile usage patterns have been realized. Small electronic devices, such as mobile phones or tablet computers, can use voice communication functions in many different situations. These occasions can be very quiet, but there can also be a lot of background noise. If the electronic device has only a single radio module, the background noise may be recorded into the voice communication, and the user's voice will be masked. In this way, the user may need to increase the volume to allow the other party to hear clearly. However, in public places, it is impolite to raise the volume, and the content of voice calls is not suitable for people around to hear. [0003] In v...
