MOBILE COMMUNICATION TERMINAL TO CALCULATE OPTIMUM DEFAULT AMPLIFICATION GAIN FOR SOUND SOURCE NOT TO BE SATURATION AND METHOD THEREOF

摘要

The present invention is coded for each source file to a different volume as the optimal amplifier gain setting default relates to a mobile communication terminal , from the output amplifier to receive the analog signal output to the speaker and the analog-to-digital converter that converts a digital signal , by detecting the output level of the analog signal input from the sound source via a digital -to-digital converter each source coded , each with different volume setting for optimal default amplifier gain , and the phone set to the output amplifier for amplifying and outputting the gain control signal corresponding to a speaker volume control stage selected by the optimal user terminal based on the default amplifier gain characterized by a control unit .
