Abstract
The utility model discloses an MP3 music player; the card reading and data memory functions to an external memory device (card) are combined on a common MP3; the inserting interface of the memory card is connected with a card reading module; the card reading module after being connected with a MCU module is integrated into a data processing module; the data processing module is respectively connected with a power module and an internal memory module; the card reading module is compatible with a plurality of external memory devices (cards) like Multi Media Card, SD Card, CF Card, Micro Driver, and the like. The MP3 fully expands the application range of the production functions, reduces the use cost and is conveniently carried under the premise of not increasing the size of the common MP3.
Description
Technical field:
The utility model relates to a kind of MP3 music player, relates in particular to a kind of MP3 music player that can read and store storing card data.
Background technology:
At present, though be that the MP3 music player of storage medium can be stored data with the flash memory, itself can not directly read and store the data in the storage card, and must be connected laggard line operate with computer, special card reader or exterior storage machine.Computer, card reader or exterior storage machine all are separate equipment, can not integrate with the MP3 player in, and volume is big, price is high, uses inconvenience.
Summary of the invention:
The utility model is designed a kind of MP3 player that can independently read and store data in the storage card, and it includes data processing module (2), power module (3), memory module (4), MCU module (5) and card reading module (6), storage card card interface (7).Storage card card interface (7) is connected with card reading module (6), and card reading module (6) is integrated into data processing module (2) with MCU module (5), and data processing module (2) links to each other with power module (3), memory module (4) respectively.
The utility model utilizes the quick DMA passage in the MP3 player itself that MCU module (5) and memory module (4), storage card (8) are coupled together, to realize the exchanges data of MP3 to storage card, so-called exchanges data is meant: the backup of the file in the storage card in the memory module (4) of MP3 player itself, the file in the memory module (4) add in the storage card (8).
The compatible multimedia card of card reading module (6) (mmc card), safe digital card (sd card), compact flash (cf card), these several model storage cards of micro hard disk are so that the utility model can use multiple storage card.
The utility model does not increase the volume of general common MP3 player, but has increased the reading and memory function of external memory card, has fully expanded the range of application of product function, has reduced use cost, and easy to carry.
Description of drawings:
Fig. 1 is a block scheme of the present utility model.
Fig. 2 is a schematic diagram of the present utility model.
Among the figure 1---the MP3 fuselage, 2---data processing module, 3---power module, 4---the storage inside module, 5 one-MCU module, 6---card reading module, 7---the storage card card interface, 8---storage card.
Embodiment:
With reference to shown in Figure 1, the utility model fuselage (1) is common MP3 player fuselage, data processing module (2) wherein is installed, power module (3) and memory module (4), power module (3) is connected with data processing module (2) respectively with storage inside module (4), be integrated with MCU module (5) and card reading module (6) in the data processing module (2), product fuselage (1) outside is equipped with storage card card interface (7), the electrical connection of storage card card interface (7) is directly connected on the card reading module (6) in the data processing module (2), and storage card (8) directly can be inserted on the storage card card interface (7).
In the time of application, at first data processing module (2) is chosen as the storage card card reading status, the storage card (8) (for example being filled with the digital camera storage card of data) of needs backup is inserted in the storage card card interface (7), data processing module (2) the deposit data in the storage card (8) in MP3 memory module (4), otherwise data processing module (2) also can be stored in the data file in the MP3 memory module (4) in the storage card (8) by storage card card interface (7).
With reference to shown in Figure 2, the data transmission of each intermodule is described in detail.
When 1) carrying out the storage card file backup, MP3 chooses picture or text (one or more) to back up in the storage card (8), open file and read file data by the file system that carries in the MP3, MCU module (5) dumps to file data in the memory module (4) of MP3 product by the DMA passage, also can browse the picture or the text of backup this moment by MP3.
When 2) carrying out to storage card (8) interior interpolation picture or file, MP3 chooses designated pictures or the file (one or more) in the memory module (4), open file and read file data by the file system that carries in the MP3, MCU module (5) dumps to file data in the storage card (8) by the DMA passage, can pass the picture of backup before back storage card (8) like this, make file freely to read and to store.
Claims (2)
1, a kind of MP3 music player that can read and store storing card data, it is characterized in that storage card card interface (7) is connected with card reading module (6), card reading module (6) be integrated into data processing module (2) after MCU module (5) is connected, data processing module (2) is connected with storage inside module (4) with power module (3) respectively.
2, MP3 music player according to claim 1 is characterized in that the compatible multimedia card of card reading module (6), safe digital card, compact flash, these several external memory cards of micro hard disk.
