Problems solved by technology

[0004] However, the SDIO expansion card is mainly connected to the electrical device through the SD memory card expansion slot, so when the electrical device only has a single SD memory card expansion slot, it can only choose between the SDIO expansion card or the SD memory card. One way to use it may be to use the method of constructing memory inside the SDIO expansion card, and at the same time have the expansion function of data storage capacity, but the SDIO expansion card is an expansion card with a specific function, and the entire SDIO expansion card must be replaced before it can be executed. Another expansion function; in other words, the data stored when using the Bluetooth function cannot be used after the GPS function, and there will be the inconvenience of repeatedly carrying memory cards and expansion cards

Abstract

The present invention discloses a memory card with expansion function. It is characterized by that it includes a memory card self-body, on the self-body a basic transmission interface is set, it also includes an expansion interface connected with internal circuit, the periphery position of circuit joint of said expansion interface is equipped with a combination portion, said combination portion can be used as combination structure of memory card and external module so as to form the circuit joint combination of expansion interface and external module. Besides, said invention also provides the application range of said memory card with expansion function.

Description

technical field [0001] The present invention relates to a memory card for electronic products, in particular to a memory card with extended functions that can be plugged into an external module to enable the electrical device to use the original storage function and perform additional functions of the external module. Background technique [0002] In the existing consumer electronic products, almost all of them are equipped with a memory card slot, allowing users to insert a memory card of a predetermined format through the memory card slot to extend the data storage capacity of the device, or to provide data storage carrier, increasing the convenience and applicability of use; the market scale of similar consumer electronics products (especially digital cameras, camcorders, MP3, mobile phones, etc.) is growing stronger, and the relative electrical devices Its own functions must also be continuously expanded and improved in order to meet the needs of consumers and obtain bas...
