Streaming media audio file play method based on mobile terminal memory card cache technology

The invention provides a streaming media audio file play method based on a mobile terminal memory card cache technology, in the method, a predetermined storage region in a memory card externally connected with the mobile terminal is used as a cache region specially used for caching the streaming media audio file, so that one or more integral streaming media audio files can be stored in the cache region, users can repeatedly listen to the audio files only by reading the cached files again without downloading from a streaming media server, time and data communication cost are saved for the users, and the cache occupies no memory capacity of a mobile terminal processor and has no influence on system processing capability of the mobile terminal; simultaneously, a technical means of the mobileterminal external memory card is mature and used widely, technicians of the field can easily set the cache region in the memory card, and maneuverability is very strong.
