Description
Affiliated technical field:
Multifunctional vehicle mounted Digital A main frame of the present utility model belongs to audio-visual equipment field and numerical information storage field, the particularly a kind of vehicle-mounted audio-visual equipment that can play the Digital A file in USB storage device or the storage card.
Background technology:
Vehicle-mounted audio-visual equipment develops into the 4th generation radio+DVD/VCD/MP3/CD CD player from first generation radio, second generation radio+magnetic tape station, third generation radio+CD CD player.Development along with network technology and digital compression technology, MP3 with it be equal to the CD CD tonequality, take memory space little, outstanding advantage such as be easy to obtain and be widely used in various amusement electronic product such as mobile phone, walkman, part the 4th generation vehicle-mounted audiovisual system main frame has also possessed MP3 dvd playback function.But present vehicle-mounted audiovisual system main frame can only be play the mp3 file that is stored in the CD, and the mp3 file in the user computer must just can be transferred to by the CD burning system of special use in the CD, like this since, cause great inconvenience for user's use.Certainly, the user also can buy the MP3 CD on market,, often having only several head in the up to a hundred first song of being stored in the CD of buying is that the user likes, the user have to not stop in the process of music appreciating presses " next song " button on the player panel, and this can make the beautiful sense of user's music appreciating all gone undoubtedly.
In order to satisfy people appreciate the MP3 music in car needs, a kind of sound signal occurred and carried out frequency modulation (FM) emission, the solution of using vehicle-mounted FM radio to receive then the output of MP3 walkman.Obviously, because interference from outside signals is added in the loss of sound signal in the modulation and demodulation process, the MP3 sound quality that final people hear is very inferior.In addition, also have the vehicle audio main frame that has audio input interface on a kind of plate in front, the sound signal of MP3 walkman output can be connected input with audio cable.This scheme usually because the output impedance of MP3 walkman and the input impedance of vehicle audio main frame do not match, and has a greatly reduced quality the tonequality of MP3 music.What allow more the user is difficult to accept is, more than two kinds of schemes owing to all need outside the vehicle audio main frame, connect auxiliary device, thereby make very mixed and disorderly that original narrow space becomes in the car.
Along with the development of video compression technology and Storage Techniques, occurred in recent years a kind of novel mobile digital amusement audio-visual products---MP4 has obtained liking of people gradually.The motorist that video display apparatus is housed opened vehicle-mounted audio-visual equipment and appreciates a film, a kind of fabulous rest and entertainment mode of can yet be regarded as in the free time of driving.Present vehicle-mounted audiovisual main frame only can DVD playing back or VCD CD, and the user not only will pay the buying expenses of CD for this reason, also to accept CD carry and use in the inconvenience that brings.If vehicle-mounted audiovisual main frame can be play popular MP4 compression of digital video file at present, can make the relaxation and happiness more that become of motorist's journey undoubtedly.The vehicle-mounted audiovisual main frame that does not also have at present to play the MP4 digital video file occurs.
Appreciating TV programme at home has been a very usual thing, see onboard that TV is not so light just, present in-car TV machine is is all installed and used separately, so not only can occupy original narrow space in the car, and can bring the trouble of a plurality of audio-visual equipment of operation.
Present vehicle audio host computer control/display panel all is made of one formula with body, sometimes since the panel color of main system of audio and user's fascia arrange in pairs or groups extremely inharmonious, thereby make user's this main system of audio of having to abandon selecting for use." changing shell " function popular on mobile phone more there is the user who follows the fashion to want to allow the automobile audio main frame of oneself possess to be similar at present.The current domestic product that does not also have to change control/display panel occurs.
Telepilot has become the standard configuration of home entertainment product, and the product of vehicle audio main frame outfit telepilot is still rare.The vehicle carried video main frame that has been equipped with telepilot brings great convenience can for undoubtedly the passenger who arranges behind the pilothouse.
Summary of the invention:
At problem described in above " background technology ", put into practice for many years in conjunction with me, the purpose of this utility model is to propose a kind ofly can play digital audio-video file (MP3/WMV/MP4), the DVD/VCD/SVCD/MP3 CD that is stored in USB storage device or the storage card, have TV/radio reception receiving function and removable host computer control/display panel, and the multifunctional vehicle mounted Digital A main frame that can use a teleswitch and operate.
The technical scheme that its technical matters that solves the utility model adopts is:
On the basis of vehicle-mounted audio-visual equipment main frame of the 4th generation (radio+DVD/VCD/SVCD/MP3/CD CD player), increase USB adapter and storage card adapter, to reach the purpose that reads the digital audio-video file that is stored in USB storage device or the storage card; The audio file data that reads is delivered to audio decoder through main control module and is decoded, and decoded voice data is delivered to D/A converter and carried out digital-to-analog conversion, and the simulated audio signal after the conversion is output after power amplifier amplifies.
The video file data that read by USB adapter and storage card adapter are delivered to Video Decoder through main control module and are carried out video data decoding and separate with audio, video data; Decoded vision signal exports video display to, and decoded voice data is delivered to D/A converter and carried out digital-to-analog conversion, and the simulated audio signal after the conversion is output after power amplifier amplifies.
On the basis of vehicle-mounted audio-visual equipment main frame of the 4th generation (radio+DVD/VCD/SVCD/MP3/CD CD player), increase television signal receiver module, control by main control module.Vision signal after the demodulation is directly exported, and sound signal is delivered to power amplifier and amplified back output.
Host computer control/display panel adopts split design, cassette to combine with body, and the circuit between the two connects by the contact, reaches the purpose of being convenient to change.The implementation of telepilot is identical with the home entertainment product, by set up the infrared remote control signal that infrared receiver receives the telepilot emission in body, delivers to the control of main control module realization to each module.
Owing to carry out technique scheme, multifunctional vehicle mounted Digital A main frame not only has the advantage of vehicle-mounted audio-visual equipment of first three generation, can also play-over the digital audio-video file (MP3/WMV/MP4) that is stored in USB storage device or the storage card, its function by network mass download and storage audio/video file can greatly be expanded people's audio-visual space.
