Abstract
The utility model discloses an automobile Flash MP3 playing controller, which belongs to the field of the techniques of an MP3 and a car audio. The running of the automobile is unbalanced, so a CD player frequently jumps on rail or stops playing, which affects to enjoy music normally. The advantages of adopting the mature MP3 technique to displace traditional CD players as below: the effect on the player when the running of the automobile is unbalanced is killed off completely; the utility model is easy to use, and the MP3 adopts a zip-out designing, which enables songs to conveniently replace and the utility model to conveniently carry; following the increase of MP3 volume, the storage capacity of songs has exceeded to CDs; the circuits of optical drive driving and control are omitted, which enables energy consumption to decrease.
Description
Affiliated technical field
The utility model relates to Flash MP3 technology and auto audio equipment technology.
Background technology
Existing auto audio equipment generally has CD-audio player or tape player, not because not steady in the running car, usually make CD Player jump onto the tracks or stop to play, influence normal Music Appreciation, the CD CD carries (area is big) and to deposit (surface easily scratches) also very inconvenient simultaneously; Tape player lower tone, capacity are little.Adopt ripe already Flash MP3 technology to replace traditional player following advantage is arranged: 1) eliminate running car fully not steadily to the influence of player.2) easy to use, because Flash MP3 adopts the detached type design, make and change song and carry very conveniently that along with the increase of Flash MP3 capacity, the storage content of song has surpassed the CD CD.3) saved CD-ROM drive driving, control circuit, energy consumption is reduced.Although the tonequality of MP3 is not as good as CD, the tonequality of present MP3 can satisfy the needs of automobile-used sound equipment fully very near CD.
The purpose of this utility model is: the defective that overcomes orthodox car CD Play System and tape Play System, Flash MP3 Play Control technology is applied to the auto audio equipment field, design with Flash is memory carrier, with MP3 is audio format, compatible WMA form can be downloaded the digital motor playing controller of MP3 melody easily from computer.
