Problems solved by technology

That is, the related art portable terminal has a problem that the frequency signal of the constant frequency band interferes with the microphone signal during the call function operation.
As a result, since a frequency signal of a constant frequency band is introduced into the signal collected by the microphone in the form of noise, the quality of the audio signal is reduced to a value less than or equal to the reference value
Therefore, it is difficult for the user of the related art portable terminal to perform a voice call due to the deterioration of the call quality

Abstract

A method of removing a microphone noise and a portable terminal supporting the same are provided. The portable terminal supporting removal of a microphone noise includes a microphone for collecting an audio signal, a controller for processing the audio signal collected by the microphone, a microphone signal line for transferring a microphone signal collected by the microphone to the controller, and a noise collecting circuit disposed at a neighboring region of the microphone signal line for collecting and providing a noise signal similar to a noise induced in the microphone signal line to the controller, wherein the controller controls such that the noise induced in the microphone signal line is removed based on the noise signal collected by the noise collecting circuit.

Description

technical field [0001] The invention relates to a microphone function. More particularly, the present invention relates to a method of providing a high-quality audio signal and a portable terminal supporting the method. Background technique [0002] Through rapid technological development, portable terminals have various functions such as a video call function, an electronic organizer function, a document function, an e-mail function, and an Internet function as well as simple voice call and Short Message Service (SMS) transmission functions. The portable terminal basically supports a voice collection function, an audio output function, and a screen display function to support a call function. [0003] A related art portable terminal includes a communication module for supporting a call function, and performs signal transmission / reception based on a constant frequency band in which the communication module operates. However, the signal transmission / reception operation of t...
