Problems solved by technology
However, the existing car navigation system can only output one sound source signal at the same time point, so when the user wants to play music at the same time in the voice navigation mode, it often occurs that the music is interrupted due to the sound of the voice navigation system; And if you want to play music sound source and navigation system sound source at the same time, and the two sound sources do not interfere with each other, the only way is to have two independent systems, so that the two sound sources are processed by different audio codecs and played by different audio output devices , but this will cause the cost to remain high, which does not meet the actual demand
[0004] Because in the existing navigation system, there is no technology disclosed to improve the above problems, it is necessary to design a system for controlling sound playback of a navigation system

The invention discloses a system and a method of a navigation system for controlling sound playing. The system of the navigation system for controlling the sound playing comprises a first sound effect codec, a second sound effect codec and a switching device; the first sound effect codec and the second sound effect codec are respectively used for processing a music sound source and a navigation system sound source output by the navigation system; and the switching device is used for switching the processed digital sound source to a proper sound source output device and outputting the processed digital sound source. The method of the navigation system for controlling sound playing is used for judging and determining the playing priority of the music sound source and the navigation system sound source output by the navigation system and selecting the proper sound source output device for outputting.
Description
technical field [0001] The invention relates to the technical field of controlling sound playback, in particular to a system and method for controlling sound playback of a navigation system. Background technique [0002] With the continuous advancement of science and technology, the installation of global satellite positioning system (GPS) and its matching navigation device on the car has gradually become popular. Car navigation systems can provide drivers with the information they need in different traffic environments at any time, and the development of voice navigation systems can prevent drivers from distracting their attention and sight from the road while driving, so as to ensure driving safety. [0003] Currently, car navigation systems are more integrated with multimedia audio-visual functions, such as music playback and video playback. However, the existing car navigation system can only output one sound source signal at the same time point, so when the user wants ...
