Description

Built-in vehicle mounted MP 3 player

Technical field

The utility model relates to built-in in-vehicle player, particularly a kind of built-in vehicle mounted MP 3 player of playing in the car with the multiple audio file of USB, MP3 and storage card storage that is implemented in.

Background technology

Since vehicle-mounted radio, broadcasting, CD player, can be in car the broadcast form of displaying audio file also along with the broadcast form of market audio file updates.Be popular at present market audio files storage and to play form be by MP3.MP3 can be from download song on the computer with certain built-in storage space, and is user's displaying audio file by playing module by earphone.Because its random updating file, memory space is big, and volume is urinated and welcome by consumers in general in advantage such as carrying.If but in car, because MP3 does not have outer playing function, audio file can only be heard by the carrier, and all people on the automobile hears in addition; There is the MP3 of foreign side's function also to embody many drawbacks owing to its acoustical quality is restricted greatly.

Summary of the invention

In view of above-mentioned prior art situation, the purpose of this utility model is can allow all people on the automobile can both hear the MP3 audio file, provide a kind of compatibility multiple built-in vehicle mounted MP 3 player especially in order to realize.This player is peripheral hardware USB interface and the memory card interface at the design of automobile gang, can be with MP3, USB, and the audio file on the storage card reaches the built-in player of sound-track engraving apparatus effect by loudspeaker, it had both realized playing the MP3 audio file in car, filled up again in car listen MP3 can not outside the blank of putting, allow the car load people can hear the MP3 audio file.The utility model is by the storage space of a built-in constant volume, can realize that plug-in device communicates by letter with the two-way unloading of built-in storage space, so just can be implemented in the song that also can hear when leaving behind MP3 among the MP3 or change song among the MP3 by player.

The technical scheme that the utility model is taked for achieving the above object is: a kind of built-in vehicle mounted MP 3 player, comprise player and built-in hard disk, and it is characterized in that, also comprise gating module, synthetic card reader, unloading module, memory card interface and USB interface; Wherein memory card interface links to each other with described gating module by synthetic card reader; USB interface directly links to each other with described gating module; USB interface, built-in hard disk, synthetic card reader and gating module link to each other with the unloading module respectively; The gating module links to each other with described player, built-in hard disk respectively, and player is connected with loudspeaker.

The utlity model has following beneficial effect: easy to use, simple to operate, can realize playing in the car audio file of multiple audio format, and then satisfy and and improve the demand of people entertainment.

Embodiment

Below in conjunction with accompanying drawing the utility model is elaborated:

The utility model comprises that player 1 and built-in hard disk 2 is characterized in that, also comprises gating module 3, synthetic card reader (4), unloading module 5, memory card interface 6 and USB interface 7; Wherein, memory card interface 6 links to each other with described gating module 3 by synthetic card reader 4; USB interface 7 directly links to each other with described gating module 3; USB interface 7, built-in hard disk 2, synthetic card reader 4 and gating module 3 link to each other with unloading module 5 respectively; Gating module 3 links to each other with described player 1, built-in hard disk 2 respectively, and player 1 is connected with loudspeaker 8.

The new novel inorganic shell of this practicality, because it is built in the automobile, embodying in the outside of automobile is exactly a USB slot and a storage card slot.Electric power system is used automobile power supply system.The storage space of a built-in constant volume, by in the plug-in device and the two-way unloading between the built-in storage space, the unloading module, the gated circuit system, built-in synthetic card reader is converted to USB interface input, the built-in in-vehicle player of simple operations system with multiple storage card.In power-on and after inserting plug-in device, how this operates with discerning the storage in the plug-in device automatically and operating system prompting user being arranged, and plays attributes section and also can select by operating system simultaneously.Can also be according to user's wish, the file in the plug-in device dumped in the built-in storage space go.If plug-in device is more than one, system automatically identification also the prompting user select to play attribute, in like manner be used for when plug-in device and built-in storage space have storage file simultaneously.By operating system, can not cause the confusion of broadcast, operation is also easily quick.One big nucleus module of player is integrated plays the demoder of the audio file of above-mentioned described multiple audio format; Another big core of the present utility model is the gating module, it is integrated to mainly contain on-off circuit, the audio file of go out to need playing when system identification is not during from a storage space, and integrated switching circuit can be opened with the path of one of them or several storage spaces and integrates playing sequence according to user's needs.Plug-in device has been connected the input and output electronic circuit with built-in storage space is middle, can intercourse memory contents.Player connects the built-in loudspeaker of automobile, provides assurance for playing tonequality.

This player is to unify power supply by the vapour utility cart, and electric power system will operate in card reader, unloading module, gating module and player.Press POWER key gating electric power system before using earlier and be connected, make player in running order with power supply between each module.The gating module will be discerned plug-in device when external slot inserts plug-in device (as: MP3, USB flash disk, storage card), by broadcast window prompting play mode, comprising: whether play, played in order, shuffle, loop play, deposit built-in hard disk in, play and deposit in option such as built-in hard disk.Option is by "+", and "-", "＜", "＞" four buttons are selected, and they also can regulate volume respectively, play next song and play the function of last first song.Insert two plug-in devices when simultaneously, when inserting simultaneously as MP3 and storage card, the prompting of broadcast window can have more that some options: MP3 preferentially plays, storage card is preferentially play, shuffle simultaneously.When having deposited file in the built-in hard disk, broadcast window can be pointed out again: changed over to USB, changed over to these unloading function choosing-items of storage card by built-in hard disk by built-in hard disk.The gating module can realize outer putting by player by loudspeaker according to user's operation fill order.
