Abstract
The present invention discloses a sound quality improvement system based on a vehicle. The system comprises a vehicle host, an isolation noise reduction module, a difference signal input module, an operational amplifier, a digital-to-analogue conversion module, a film capacitor, a high-fidelity power amplifier and a loudspeaker. The vehicle host is connected in order with the isolation noise reduction module, the difference signal input module, the operational amplifier, the digital-to-analogue conversion module, the film capacitor, the high-fidelity power amplifier and the loudspeaker. The sound quality improvement system based on the vehicle employs difference signal input to greatly remove the external electromagnetic interference and improve the signal output efficiency; and moreover, the sound quality improvement system based on the vehicle employs the isolation noise reduction module to effectively eliminate the problem caused by the wire resistance and eliminate the noise caused by an automobile electric device.
Description
Technical field
The present invention relates to a kind of sound system, specifically a kind of lift system based on automobile.
Background technology
Nowadays automobile is all constantly increasing every year in China's quantity, and requirement of the users to in-car experience is also increasingly
Height, wherein, the in-car acoustical quality for playing music is users' emphasis of interest, so the repacking of automobile audio by
Gradually become the focus of automotive electronics repacking at present.
Prior art substantially has the following two kinds to be capable of achieving in-car acoustical quality lifting
One. the former Main Engine of repacking and power amplifier, main frame is the source of sound of whole sound equipment, and a control centre, to sound equipment
All by main frame realizing, built-in power amplifier is strengthening signal for control.But main frame repacking is expensive, and main frame is changed
Dress also can to a certain degree have influence on the overall complexion of in-car script.
Two. the speaker of the former car of repacking, speaker are commonly called as loudspeaker, signal are become the mechanism of sound.High-quality is raised one's voice
Lifting of the device to acoustical quality is significant.But equally its price is not low, while reequiping loudspeaker will also increase necessary wire harness,
So the uncertainty of the cost of wire harness and wiring is also that user is to be considered.
The content of the invention
It is an object of the invention to provide a kind of tonequality lift system based on automobile, to solve to carry in above-mentioned background technology
The problem for going out.
For achieving the above object, the present invention provides following technical scheme：
2. a kind of tonequality lift system based on automobile, is input into mould including on-vehicle host, isolation noise reduction module, differential signal
Block, operational amplifier, D/A converter module, thin-film capacitor, high-fidelity power amplifier and speaker, it is characterised in that the vehicle-mounted master
Machine is sequentially connected isolation noise reduction module, differential signal input module, operational amplifier, D/A converter module, thin-film capacitor, Gao Bao
True power amplifier and speaker；Signal is amplified by the operational amplifier.
Compared with prior art, the invention has the beneficial effects as follows：1. it is input into using differential signal, can greatly removes outside
Electromagnetic interference, while improve signal output frequency.2. effectively eliminate what conductor resistance caused using isolation noise reduction module
Problem, and eliminate the noise caused by auto electric equipment.3. thin-film capacitor insulation impedance is high, and frequency response is wide, dielectric loss
Little, the electric capacity of increase is made to install additional power amplifier and is matched with the capacitance of former car, it is to avoid because installing that power amplifier power is big additional and vehicle-mounted capacitor
The unnecessary trouble not enough brought by electricity.4. high-fidelity power amplifier by the audio signal amplified through prime be amplified for
Drive the speaker, this power amplification distortion rate are little, can preferably ensure the stability of signal.
Description of the drawings
Fig. 1 is the schematic block circuit diagram of the tonequality lift system based on automobile.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1 is referred to, in the embodiment of the present invention, a kind of tonequality lift system based on automobile, including on-vehicle host, isolation
Noise reduction module, differential signal input module, operational amplifier, D/A converter module, thin-film capacitor, high-fidelity power amplifier and raise one's voice
Device, the on-vehicle host be sequentially connected isolation noise reduction module, differential signal input module, operational amplifier, D/A converter module,
Thin-film capacitor, high-fidelity power amplifier and speaker；Signal is amplified by the operational amplifier.
The present invention operation principle be：Fig. 1 is referred to, the audio signal of former Main Engine output first passes around prime isolation
Noise reduction module process reduces the back drop caused by electromotor and other electric equipments, it is ensured that sound is purer；After noise reduction
The prime low level signal amplification that will be input into via operational amplifier of the mode that is input into by differential signal of audio signal；Digital-to-analogue conversion mould
The digital audio and video signals amplified through prime are converted into analogue signal by block；The thin-film capacitor increased in circuit guarantees that signal is being passed
There is no too big distorted signals during defeated；Final driving is amplified by the power amplifier of high-fidelity after audio signal
Speaker sends sound.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of spirit or essential attributes without departing substantially from the present invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit is required rather than described above is limited, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as and limit involved claim.
Moreover, it will be appreciated that although this specification is been described by according to embodiment, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of description is only that those skilled in the art should for clarity
Using description as an entirety, the technical scheme in each embodiment can also Jing it is appropriately combined, form those skilled in the art
Understandable other embodiment.
