Communication terminal and audio gain parameter regulation method

Abstract

The invention provides a communications terminal and an audio parameter adjustment method thereof. The method comprises: receiving an audio electrical signal from a network side; performing a sound volume gain processing to the audio electrical signal according to a set audio gain parameter; transferring the audio gain processed audio electrical signal to a sound signal to output; detecting the sound volume of the output sound signal and comparing the same with a presetting sound volume reference value; adjusting the set audio gain parameter according the difference of the detected sound volume and the presetting sound volume reference value. The example of the invention implements the automatic dynamic adjustment of the terminal audio gain parameter and shields the difference of the sound volume transmitted by opponents in the network and communication.

Description

technical field [0001] The invention relates to a communication terminal, in particular to a communication terminal for dynamically adjusting audio gain parameters and a method for adjusting the audio gain parameters. Background technique [0002] For current communication terminals such as mobile phones, the sound equipment is mainly divided into two parts: a sending (TX) part and a receiving (RX) part. like figure 1 As shown, when the sound signal is sent, the sound signal is collected by a microphone (MIC), and the sound signal is converted into an audio electrical signal, and then the audio processing unit utilizes predetermined audio parameters (including audio gain parameters) to process the audio electrical signal. The signal is subjected to audio processing such as gain amplification, and finally sent to the network side; when receiving sound, the audio electrical signal transmitted from the network side needs to be processed using predetermined audio parameters (in...

Problems solved by technology

[0005] In the process of realizing the present invention, the inventor found that: the audio gain parameters determined by the above test method are not only limited by the subjective feelings of the testers, but also affected by the transmission volume of network A and UE2 during actual use. Limitations. In actual use, the volume gain parameter is fixed. As long as any one of the transmission volume conditions of network A and UE2 changes, the volume of the sound emitted by UE1's speaker will deviate from the original volume. When the network environment is extremely bad or the sending volume of the other terminal is too high or too low), the deviation will be very large. Therefore, due to the inconsistency of the sending volume of different terminals and the differences in the network environment, it will cause the terminal to receive from the network side. The volume of the audio signal is inconsistent, so the volume of the sound played on the final speaker (SPEAKER) is inconsistent, which greatly affects the user's use and causes inconvenience to the user
