Device with terminal communication noise suppression function, method and communication terminal

Abstract

The invention discloses a device with the terminal communication noise suppression function, a method and a communication terminal, and the device comprises a main control chip of the terminal, a first analog switch, a main microphone used for collecting non-earphone communication sound and a reference microphone used for collecting communication noise of the terminal; wherein an output end of the first analog switch is connected with a first microphone interface of the main control chip of the terminal, and the main microphone and the reference microphone are respectively connected with two input ends of the first analog switch; and the main control chip of the terminal is used for controlling the first analog switch to communicate the main microphone and the reference microphone with the main control chip through the time division multiplexing way and collecting the communication sound of the main microphone and the communication noise of the reference microphone for carrying out noise suppression treatment. The device, the method and the communication terminal can reduce the wiring space of a mainboard and effectively save hardware cost while effectively suppressing the communication background noise.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a device, method and communication terminal with a terminal call noise suppression function. Background technique [0002] With the increasingly widespread use of various communication terminals such as mobile phones, the use environments of various terminals are also different. For example, people often use mobile phones in noisy environments such as buses and downtown. In these environments, the other party's caller can often not hear the voice in the mobile phone clearly. Since people pay more attention to the call quality of various communication terminals in various environments, even in noisy environments such as busy streets or gathering places, they hope to have stable, reliable, and clearly distinguishable calls. The other party can talk clearly and enjoy the whole process of the call. [0003] At present, the method for suppressing the background noise of the call...

AI Technical Summary

Problems solved by technology

However, the noise suppression chip is expensive and has many interfaces. It requires I2C, crystals, various resistors and capacitors, and matching circuits. It takes up a lot of space on the motherboard and has a lot of wiring. , which greatly limits the application of this scheme on many communication terminals such as mobile phones
