MOBILE TELECOMMUNICATION UNIT CONFIGURABLE TO CONNECT TO A SUPPLEMENTARY MODULE

摘要

A mobile telephone unit has a cavity for receiving a supplementary module, which is enabled to store and decompress media data files, especially audio data files in the MP3 format. The mobile telephone unit includes a data transfer port for connection directly to a corresponding data transfer port of the supplementary module, so that the mobile telephone unit can functionally interact with the supplementary module, to transfer data to the mobile telephone unit and/or from the mobile telephone.
