Definitions

  • the invention relates to a device for the playback of MP3 files, which can be coupled to a playback control device such as an amplifier or a radio. It relates in particular to an additional device that can be connected or plugged into a car radio instead of or in addition to a CD changer.
  • the object of the invention is therefore to create a device unit which on the one hand uses all existing music sources, but eliminates the disadvantages of the devices available in the prior art.
  • the device for the playback of MP3 files according to the present invention which can be coupled to the audio input of a playback control device, is characterized in that at least one storage device with MP3 files is provided which is connected to the audio input via an MP3 processor of the playback control device can be connected, and that the control inputs and outputs of the storage means and the playback control device are coupled to a microprocessor or a microcontroller unit.
  • the storage means can be portable or non-portable and can consist of a CD-ROM, a SMART media card, a hard disk, RAM or the like, it also being possible for several different portable or non-portable storage means to be present, which can optionally be activated.
  • the device for playing MP3 files according to the present invention can also be incorporated in addition to a CD changer.
  • a special embodiment arises when, in addition to the storage means, a communication module is present that can be coupled with a remote data transmission. This makes it possible to transfer MP3 files directly from the Internet or a digital radio station.
  • the advantage of the inventive device is above all that no audio CD has to be played anymore. These advantages are particularly great when it comes to a CD changer in a motor vehicle.
  • Playback of MP3 files playable CD according to the present invention can be produced beforehand using a CD burner according to ISO 9610.
  • the data compression is so remarkable that the data volume of up to 20 audio CDs can be stored on an MP3 CD. This eliminates the need for a CD changer.
  • An anti-shock system is due to the strong compression of the data from e.g. 10 s extended to 2 min if the usual storage capacity is maintained.
