Abstract

The invention discloses a volume self-adaption method for a vehicle-mounted entertainment system, and the method comprises the steps: S1, calculating a sound parameter of a sound source signal according to the sound source signal of music played at a current foreground, and enabling a user to achieve an ideal value of the volume of the played music by adjusting the sound parameter; s2, obtaining an effect characteristic value A0 according to the adjusted volume parameter; s3, when the background is connected with other sound source signals, calculating a sound parameter Cx, taking Cx and A0 as input, and outputting a configuration parameter Bx; and S4, when the sound source signal connected to the background is switched to the foreground for playing, outputting according to the corresponding output configuration parameter Bx. According to the invention, automatic volume adjustment during sound source signal switching is realized.

Description

technical field [0001] The invention relates to the field of in-vehicle media playback, in particular to a volume adaptive method for an in-vehicle entertainment system. Background technique [0002] In the current car central control system, there are multiple sound source modes, and each sound source is mutually exclusive. When the user is under one sound source, the current sound source outputs a piece of data, and the user adjusts the car machine interface to let the final The output sound source reaches a suitable loudness. However, when the user needs to switch the sound source to another sound source mode, due to the differences in the resources of the two sound sources, there will be situations where the volume is too loud or too low after switching, which will affect the experience of passengers and even more seriously endanger driving. Safety. Contents of the invention [0003] The purpose of the present invention is to provide a volume adaptive method for a ca...
