The keypoints of the technical proposal is that an electronic circuit board is arranged in an enclosure; a socket for a mobile flash disk is prepared on the enclosure, and the mobile flash disk is plugged into the socket; a display panel and a connection control assembly are arranged on the enclosure. The utility model has a simple, compact and rational structure; the adopted flash disk has sound anti-shock performance, and the flash disk is cheap and reliable for storing media files, and the song names and other information can be displayed on the LCD arranged in the automobile; to exchange music files between the flash disk and a computer is very easy; the flash disk does not need any space to place tapes, discs, etc; the flash disk is capable to record, receive broadcast and store files, and display the time; and the flash disk can be taken out from time to time.

Description

Automobile digital music flash disk device

Technical field:

The utility model relates to a kind of automobile digital music flash disk device, is used for the music system on the automobile, belongs to the accessory on the automobile.

Background technology:

Before the utility model was made, the music system that is used on the automobile was supporting, normally adopted tape storage formula (simulating signal) and two kinds of structures of optical disc storage formula (digital signal).The tape storage formula is to use the tape storage simulating signal, adopts machinery and electronic equipment to extract music signal.The tape storage formula of this kind structure, the music distortion rate is higher, and acoustics is undesirable; Because all prior packaged song that oneself can not be liked of tape concentrates in the finite storage space, need take limited interior space so increase music tape; Because of adopting simulating signal, also just title of the song can't be presented on the panel.Optical disc storage formula structure all is that the in advance packaged song that oneself can not be liked listening concentrates in the finite storage space because of CD also, so need take limited interior space equally as increasing music CD; Because of the limitation of CD itself, title of the song can't be presented on the panel; As adopt optical-disk type physical construction, be easy to generate fault; Because shaven head reads for a long time, will shorten its serviceable life, in addition as needing buffer memory part music, so cost is higher.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple, compact and reasonable for structure; Can utilize on the market existing flash disk as medium, low price, stable performance, shock resistance is good, does not need to take the automobile digital music flash disk device that article such as tape, CD are placed in space limited in the car.

Main solution of the present utility model is achieved in that

The utility model mainly adopts electronic circuit board 11 to be installed in the housing 10, is shaped on movable flashing dish skewer inlet 9 on housing 10, and movable flashing dish 1 skewer is gone in the movable flashing dish skewer inlet 9, and display panel 8 and wiring control assembly 12 is housed on housing 10.

Be equipped with on the utility model wiring control assembly 12 that volume increases knob 2, volume reduces knob 3, power knob 4, next song button 5, last one first button 6 and the mode button 7 sung.

Compared with the prior art the utility model has the following advantages:

The utility model is simple, compact and reasonable for structure; Adopted existing flash disk on the market, had fine shock resistance, utilized flash disk as medium, low price, stable performance can show information such as title of the song by the liquid crystal display in the car; Use flash disk and computer switching tone music file very convenient; Do not need to take space limited in the car and place article such as tape, CD; Can recording, radio reception, storage file, and free demonstration, can at any time the movable flashing dish be taken out.

Embodiment:

Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:

The utility model mainly is made up of housing 10, electronic circuit board 11, wiring control assembly 12, movable flashing dish 1 etc.Movable flashing dish 1 skewer is gone in movable flashing dish skewer mouth 9, and electronic circuit board 11 is installed in the housing 10, and LCD backlight display panel 8 and wiring control assembly 12 are installed on housing 10.Settle on the wiring control assembly 12 volume increase knob 1, volume reduce knob 2, power knob 4, next song button 5, on a first song button 6 and a mode button 7 (radio reception, playback, recording).

The utility model adopts the flash memory storage module on electronic circuit board 11, the FM radio module, LCD MODULE backlight, power module, operating system storage chip, button control assembly, vehicle-mounted loudspeaker, the input of microphone source of sound etc. are connected with the source of sound decoding chip by lead respectively, also can adopt the computing machine skewer to go into USB interface and insert source of sound decoding chip transmission audio files.

The principle of work of the present utility model and the course of work:

When the utility model uses movable flashing dish skewer is gone into movable flashing Pan Qiankou, the movable flashing dish is popular in the market flash disk, turns on the power switch, and selects radio reception, playback, recording by mode button; Select song or the channel play by last one first song button or next song button, reduce or volume increases volume in the knob controlling car by volume; Owing to adopt flash disk as medium, also can exchange digital music file (MP3, WMA) etc. with computing machine easily, in flash disk skewer incoming interface, after connecting digital circuit, digital circuit is extracted music signal from flash disk, and carry out amplifying signal by the power amplifier that inside carries, and the outputting music signal drives the vehicle-mounted loudspeaker in the car.
