Abstract

The invention discloses an information processing method and an electronic device. The method is applied to an electronic device including a first microphone and a second microphone. The method includes: at the first moment when the first microphone and the second microphone are turned on, the first The first information collected by the microphone is used as the target voice information, the second information collected by the second microphone is used as the environmental noise information, and the first angle value between the electronic device and a preset plane is detected by detection; at the second moment, the detection Obtaining a second angle value between the electronic device and a preset plane; judging whether the first difference between the first angle value and the second angle value is greater than a set threshold; when the first difference is greater than the set threshold, turning the first microphone The third information collected is used as environmental noise information, and the fourth information collected by the second microphone is used as target voice information. Through the above technical solution, the technical problem in the prior art that the functions of the primary and secondary MICs cannot be interchanged is solved, and the accuracy of noise reduction processing is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an information processing method and electronic equipment. Background technique [0002] From the end of the 19th century, scientists such as Bell invented liquid microphones and carbon particle microphones in order to improve the latest invention of the telephone at that time. People have been working hard to obtain high-definition, low-noise sound signals. [0003] Nowadays, the application of dual MIC (microphone) can well reduce the environmental noise in the voice information signal. The realization principle of dual MIC is mainly to configure two microphones on the electronic device: the main MIC and the sub-MIC, and make the main MIC collect more target sounds, and the sub-MIC collects more environmental noise, based on the sound collected by the sub-MIC , Eliminate the ambient noise collected by the main MIC to get a clear target voice. [0004] However, in the proc...
