Description
Technical field
This utility model belongs to Audiotechnica, is specifically related to same audio frequency adaptation simulation in a kind of communication controller and vehicle
System with difference two class source of sound.
Background technology
Car load there are two kinds of sights can use car load mike, the first sight: seeking help in case of emergency function, user voice warp
Cross mike and change into single-ended analog audio electrical signal entry communication controller, be switched to by analog switch in communication controller
Audio processing modules, then by audio processing modules single-ended analog audio electrical signal be converted into wireless signal be sent to backstage sit
Seat.The second sight: speech identifying function, user voice changes into single-ended analog audio electrical signal entry communication through mike
Controller, by analog switch switching output to entertainment systems main frame in communication controller, after entertainment systems host process, holds
Row identifies function accordingly.When single-ended analog audio electrical signal transmits in vehicle, owing to voltage is relatively low, generally 5V or 8V, holds
It is vulnerable to the interference of car load electromagnetic environment, so that cross-talk (such as: the noise of interference) in the sound of speech recognition, and then affect language
The accuracy of sound identification.
Summary of the invention
The purpose of this utility model is to provide the simulation of same audio frequency adaptation and difference two in a kind of communication controller and vehicle
The system of class source of sound, can improve the rejection ability to common mode disturbances.
Communication controller described in the utility model, including:
Audio processing modules, for being converted into wireless signal by single-ended analog audio electrical signal；
Differential processing module, for being converted into difference audio electrical signal by single-ended analog audio electrical signal；
Analog switch, it has input, the first outfan and the second outfan；The input of analog switch is used for and wheat
Gram wind connects, and the sound received is converted to single-ended analog audio electrical signal by mike；First output of described analog switch
End is connected to described audio processing modules, is used for controlling whether to export from described mike to the transmission of described audio processing modules
Single-ended analog audio electrical signal；Second outfan of described analog switch is connected to described differential processing module, is used for controlling
Whether transmit, to described differential processing module, the single-ended analog audio electrical signal exported from described mike.
The simulation of same audio frequency adaptation and the system of difference two class source of sound in a kind of vehicle described in the utility model, including wheat
Gram wind, backstage are attended a banquet, entertainment systems main frame and communication controller described in the utility model；
The input of described analog switch is connected with mike；
Described audio processing modules is attended a banquet with backstage and is connected；
Described differential processing module is connected with entertainment systems main frame.
The beneficial effects of the utility model: when system is in seeking help in case of emergency function, user voice converts through mike
Enter communication controller after becoming single-ended analog audio electrical signal, in communication controller, be switched to Audio Processing mould by analog switch
Block, then be sent to backstage after single-ended analog audio electrical signal being converted into wireless signal by audio processing modules and attend a banquet；In system
When being in speech identifying function, user voice enters Communication Control after mike changes into single-ended analog audio electrical signal
Device, is switched to differential processing module by analog switch in communication controller, by difference processing template single-ended analog audio-frequency electric
Signal changes into difference audio electrical signal, then output is to entertainment systems host process, performs to identify function, difference audio-frequency electric accordingly
Signal is effectively improved in output the rejection ability to common mode disturbances.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model；
In figure: 1, mike, 2, communication controller, 3, analog switch, 4, audio processing modules, 5, differential processing module,
6, attend a banquet in backstage, and 7, entertainment systems main frame.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
Communication controller as shown in Figure 1, including audio processing modules 4, differential processing module 5 and analog switch 3.Audio frequency
Processing module 4 is for being converted into wireless signal by single-ended analog audio electrical signal.Differential processing module 5 is for by single-ended analog sound
Frequently the signal of telecommunication is converted into difference audio electrical signal.Analog switch 3 has input, the first outfan and the second outfan；Simulation
The input of switch 3 is for being connected with mike 1, and the sound received is converted to single-ended analog audio electrical signal by mike 1；
First outfan of analog switch 3 is connected to audio processing modules 4, be used for controlling whether to audio processing modules 4 transmit from
The single-ended analog audio electrical signal of mike 1 output；Second outfan of analog switch 3 is connected to differential processing module 5, is used for
Control whether to transmit the single-ended analog audio electrical signal from mike 1 output to differential processing module 5.
The simulation of same audio frequency adaptation and the system of difference two class source of sound in vehicle as shown in Figure 1, including mike 1, after
Platform is attended a banquet 6, entertainment systems main frame 7 and communication controller of the present utility model 2.The input of analog switch 3 is with mike 1 even
Connect；Audio processing modules 4 is attended a banquet with backstage and 6 is connected；Differential processing module 5 is connected with entertainment systems main frame 7.
When system is in seeking help in case of emergency function, user voice changes into single-ended analog audio electrical signal through mike 1
Rear entrance communication controller 2, is switched to audio processing modules 4 by analog switch 3 in communication controller 2, then by Audio Processing
4 single-ended analog audio electrical signals of module are sent to backstage and attend a banquet 6 after being converted into wireless signal；It is in speech recognition merit in system
