Abstract

The utility model discloses a music player in which a master chip (used for deciphering the network music), a program storage unit and a USBHOSTCPU (USB mainframe) are arranged. A USB mainframe interface and an external storage unit which can be connected with the USB mainframe interface are arranged on the music player. When the music player is used, the external storage unit can be connected with the music player through the USB mainframe interface, and then the external storage unit passes through the USBHOSTCPU (USB mainframe). Therefore the memory is conveniently extended. The music files stored in the external storage unit can be played.

Description

A kind of music player

Technical field

The utility model relates to a kind of technical field of digital music playing device, refers to that especially a kind of usb host interface that adopts is connected with outside memory device, and can play the music player that is stored in the music file in the external memory storage.

Background technology

At present, existing player is made up of built-in storer and demoder, song and procedure stores in built-in memory device, play by the master chip reading of data, because general various flash memories of employing of general memory device or hard disk are the storage medium of music, it is built-in mostly, is not easy to change, and also is not easy expansion when the needs capacity enlarges; And along with development of science and technology, USB flash disk (or storer of USB interface) is as a kind of external memory storage now, be widely used, it can be used to store music file, and have some players that the function of exented memory is arranged, but the interface section can not directly use the usb host interface to connect memory storage.

The utility model content

The purpose of this utility model is to provide a kind of music player that makes things convenient for exented memory.

For achieving the above object, solution of the present utility model is: a kind of music player, include a master chip, program storage, USB HOST CPU (usb host) in it, and also have the usb host interface on it.

Described a kind of music player also is provided with internal memory on it.

Described a kind of music player, it also includes the external memory that connects with the usb host interface.

Described a kind of music player, its described external memory is a USB flash disk.

After adopting said structure, during use, external memory can insert this music player by the usb host interface, and again by decoding device, thereby realization makes things convenient for the purpose of exented memory, reaches and can play the effect that is stored in the music file in the external memory storage.
