Abstract

The present invention provides a mobile terminal and a control method, the mobile terminal includes: an audio codec, and a control chip, the audio codec has a channel output pin; the control chip is connected to the audio codec connected, the control chip is used to output a compensation voltage signal to the audio codec during the opening and closing process of the audio codec, so that the audio codec is in the opening and closing process, the The DC bias voltage of the channel output pin is 0V. The embodiment of the present invention eliminates the POP sound generated by the mobile terminal, and improves the effect of using the earphone.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a mobile terminal and a control method. Background technique [0002] As we all know, the earphone function is one of the important functions of the mobile terminal, through which the user can listen to music, make phone calls, and live broadcast. Therefore, the signal quality of the voice signal of the earphone path will directly affect the experience of the user. In the existing mobile terminal, before the voice signal is played through the earphone for the user to perceive, the voice signal needs to be sent to the audio codec Codec IC for audio decoding processing. Due to the process and consistency of the audio codec, there is usually a DC component of tens to hundreds of uV, or even tens to hundreds of mV during the turn-on and turn-off process. This weak DC component acts on the earphone Above, a POP sound (that is, a crackling sound) will be produced. Co...
