Audio, while automatically the audio of loading current audio source is arranged when source is cut, make user obtain more preferable operating experience.
2nd, built-in sound effect control can mutually switch with external DSP sound effect controls, and external DSP sound effect controls have more strengthen
Big sound effect control ability.
Description of the drawings
Fig. 1 is the flow chart of the sound effect control method of the vehicle carried video system of the present invention.
Fig. 2 is the connection diagram between the main frame and external digital signal processor (DSP) of vehicle carried video system.
Specific embodiment
With reference to the accompanying drawings and examples the present invention is further described, and the content of embodiment is not as the guarantor to the present invention
The restriction of shield scope.
Fig. 1 shows the flow chart of the sound effect control method of the vehicle carried video system of the present invention.As shown in figure 1, of the invention
The sound effect control method of vehicle carried video system comprise the following steps：
First, each audio-source by the built-in equalizer (EQ) of vehicle carried video system for vehicle carried video system sets respectively
Put corresponding audio.In the present invention, described each audio-source includes radio reception, media and bluetooth etc..It is, user can be with root
The built-in EQ for passing through vehicle carried video system according to the demand of oneself is that radio reception, media and bluetooth etc. are respectively provided with corresponding audio, with
Meet oneself audio demand to various audio-sources.
Secondly, after corresponding audio is set for each audio-source, the audio arranged for each audio-source is all read
In entering shared drive, in order to preserving and reading.
When audio-source switching is carried out, it is, when another audio-source is switched to from an audio-source, for example, from
When radio reception is switched to media, the message for carrying the information of another audio-source can be sent to the built-in equilibrium
Device.
In the present invention, the information of another audio-source is the ID of another audio-source.It is, will carry
The message for having the ID of another audio-source is sent to the built-in equalizer.So, the built-in equalizer is known that described
Another audio-source, it is, which audio-source the target audio source to be switched is.
The built-in equalizer input preserves the corresponding audio of one audio-source and loads institute to after the message
State the corresponding audio of another audio-source.
Using the sound effect control method of the vehicle carried video system of the present invention, when user enters EQ under such as radio receiver mode
Audio (it is assumed that audio 1) is set, is then switched to and enter under such as USB mode EQ settings audio (it is assumed that audio 2), now again
It is still audio 1 that audio is arranged when switchback radio receiver mode listens radio reception, and it be still then audio 2 that audio is arranged when switching to USB mode.This
Sample, realizes point source storage of audio setting with Dynamic Recognition and loads the audio of current audio source automatically, user is obtained more
Good operating experience.
Additionally, in the present invention, after the corresponding audio of described another audio-source is loaded with, to start described another
Individual audio-source.If now user wants to change the corresponding audio of described another audio-source, the built-in equalizer can be passed through
For described another audio-source, another corresponding audio is set.So, the dynamic knowledge of the corresponding audio of audio-source can either be realized
Not and automatically load, the artificial setting of the corresponding audio of audio-source can be realized again, meet various demands of user.
In addition, in order to have more powerful sound effect control ability, the sound effect control method of the vehicle carried video system of the present invention
The audio that may further include built-in equalizer arranges the mutual function arranged with the audio of external digital signal processor.
Specifically, make the built-in equalizer and external digital signal processor can arrange vehicle carried video system each
The corresponding audio of audio-source, and make the audio setting function of the built-in equalizer and the sound of the external digital signal processor
Effect arranges function can mutually be switched.
When the audio that the audio setting function from the built-in equalizer is switched to the external digital signal processor is cut
When changing function, the built-in equalizer can be resetted and be exited by the main frame of vehicle carried video system, while starting the external numeral
Signal processor controls the corresponding audio of each audio-source.
As shown in Fig. 2 in the present invention, the main frame 1 of the vehicle carried video system is external with described by serial ports control line 4
Digital signal processor 2 communicates.Instruction of the main frame 1 of the vehicle carried video system according to the external digital signal processor 2
The digital signal processor 2 is given by host audio signal output, then is exported audio signal by the digital signal processor 2
To loudspeaker 3.So so that the digital signal processor 2 can realize the setting of the audio to each audio-source.
In the present invention, because main frame 1 controls process of the external DSP2 to audio signal, the external DSP2 by serial ports
Sound effect control have more powerful sound effect control ability, mainly include：1st, during user can be adjusted in 20Hz-20KHz arbitrarily
The gain of frequency of heart and Q-value；2nd, the independent control of sound field audio and mutual covering function in front and back；3rd, 3D and Bass effects；4、
Front sound field, rear sound field, the filter function (allowing user that filter low pass high pass cut off frequency and slope are set) of bass；5、
The acoustic gain of FL, FR, RL, RR, SUB, time delay, phase place are individually controlled.Accordingly, it is capable to provide the user more rich audio effect processing
Experience and more powerful sound effect control ability.
The above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not to the present invention
Embodiment restriction.For those of ordinary skill in the field, can also make on the basis of the above description
The change or variation of other multi-forms.Here all of embodiment cannot be exhaustive.Every skill for belonging to the present invention
Obvious change that art scheme is extended out changes row still in protection scope of the present invention.
