The invention discloses a mobile terminal. The mobile terminal includes a compiling decoder; the audio output positive end of the compiler-decoder is respectively connected with drain electrodes of the NMOS tube, the second NMOS tube and the third NMOS tube; the audio output negative end of the compiler-decoder is respectively connected with one end of the HAC inductor, One end of a matching resistor, and One end of the loudspeaker and receiver combination assembly;. the source electrode of the first NMOS tube is connected with the other end of the HAC inductor; the source electrode of the second NMOS tube is connected with the other end of the matching resistor; the third NMOS tube is connected with the other end of the loudspeaker receiver combined assembly; wherein the first GPIO interface is connected with the grid electrode of the first NMOS tube, the second GPIO interface is connected with the grid electrode of the second NMOS tube, the third GPIO interface is connected with thegrid electrode of the third NMOS tube, and the audio output positive end and the audio output negative end are respectively connected with the AB-type amplifier and the D-type amplifier. In addition,the invention also discloses an audio signal processing method of the mobile terminal and a storage medium. According to the mobile terminal disclosed by the embodiment of the invention, the audio performance can be improved.
Description
technical field [0001] The present invention relates to the technical field of mobile terminal control, in particular to an audio signal processing method of a mobile terminal, a mobile terminal and a storage medium. Background technique [0002] Currently on the market, mobile terminals with hearing aid functions are provided for elderly people who are hard of hearing or for people with hearing impairments. When the mobile terminal supports the hearing aid function, the earpiece needs to select the earpiece with the hearing aid function, and due to structural constraints, many mobile terminals choose a two-in-one speaker / earpiece, that is, mobile terminals mostly use a dual speaker and earpiece. All in one component. However, the audio performance is relatively poor due to the relatively low matching degree of the selected circuit path between the speaker earpiece joint assembly and the hearing aid compliance (Hearing Aid Compliance, HAC) inductor.
