The AUX input interfaces that one group of original audio signal carries the loudspeaker by car audio unit enter, amplified to exist again
Released in the loudspeaker of car audio unit.By appropriate adjustment, the loudspeaker of car audio unit are with increased left and right sound equipment loudspeaker
Can organically merge, in-car sound equipment will be lifted greatly.
Brief description of the drawings
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail, wherein：
Fig. 1 is the circuit block diagram of the utility model embodiment.
Embodiment
With reference to Fig. 1, a kind of new automobile audio system, including automobile power supply system and car audio unit, its feature exists
In, in addition to Bluetooth receptions module and be sequentially connected with Bluetooth receptions module output end signal processing module, power amplifier module and
Music centre loudspeaker, the Bluetooth receptions module output end is also associated with first processor, the Bluetooth receptions module input with it is outer
Portion processor connection, first processor output end is connected with signal processing module, signal processing module output end also with automobile sound
Frequency unit is connected.
The signal processing module include second processor and D/A converter, the D/A converter output end respectively with work(
Amplification module and the connection of car audio unit.The car audio unit includes amplifier, and the amplifier in is respectively with the
One AUX input interfaces, USB, radio and CD connections, the amplifier out respectively with left front loudspeaker, it is right before loudspeaker, it is left back
Loudspeaker are connected after loudspeaker and the right side, and the D/A converter output end is connected with AUX input interfaces.
Bluetooth receptions module input is also associated with microphone, and the microphone output end is connected with second processor, institute
First processor is stated using microprocessor MIC, the second processor uses DSP, first processor output end and second processing
Device is connected, and second processor input is also associated with the 2nd AUX input interfaces, and the audio of microphone can enter line frequency by DSP
Correction, coordinates matched microphone, realizes the effectiveness received calls in the car, kills two birds with one stone.
From the audio signal received by bluetooth or the 2nd AUX input interface line inputs, second processing can be sent to
Device DSP carries out signal transacting, and first processor sends commands to the letters such as second processor DSP addition reverberation delay, frequency equilibrium
Number processing, the audio signal that optimized of output two-way, the first AUX inputs that first wife's car audio unit is routed directly to all the way connect
Mouthful, it is amplified and is output on the loudspeaker of former car by amplifier, due to the processing by second processor DSP, signal is obtained
Optimization, can greatly promote the performance level of former car sound equipment；And signal has then carried out band logical by second processor DSP all the way in addition
Filtering, is then output to power amplifier module, and the loudspeaker and built-in horn that the signal after amplification is sent to left and right sound channels respectively are worked as
In, so that frequency response complementation and acoustic image complementation are carried out with former car sound system, so as to greatly promote automobile audio level.
