Embodiment
The invention provides a kind of micro SD card and the mobile phone with Wi-Fi function, for making object of the present invention, technical scheme and effect clearly, clearly, referring to accompanying drawing examples, the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The present invention is a kind of micro SD card with Wi-Fi function, its profile is the micro SD card of standard, and micro SD draw-in groove is the device of each mobile phone indispensability substantially, by user can be allowed to buy the voluntarily expansion that micro SD card carries out external memory storage of micro SD draw-in groove, realization of the present invention is exactly based on above-mentioned design, as shown in Figure 1, the micro SD card of the described Wi-Fi of having function comprises a micro SD card body 111, be arranged on the micro SD card interface 103 on described micro SD card body 111, be arranged on the storage device 100 in described micro SD card body 111, Wi-Fi module 105, and analog switch 102.
By storage device 100 and Wi-Fi module 105 connecting analog switch 102 in the present embodiment, described analog switch 102 is connected with micro SD card interface 103, and micro SD card interface 103 is connected with mobile phone by the SDIO interface of standard.
The effect of described analog switch 102 realizes storage device 100 on same SDIO interface, with sharing of Wi-Fi module 105 SDIO interface, that is, makes micro SD card not only have memory function by analog switch 102, also can realize Wi-Fi function.Message transmission rate due to the Wi-Fi of current phone use is the highest in theory can reach 75Mbps, but generally about can reach 10Mbps in practice; The bandwidth of general analog switch 80 Mbps reached as high as the SD card speed meeting SD2.0, so will be not less than 100Mhz simultaneously.
The effect of described storage device 100 can realize the extension storage function of common micro SD card, and described Wi-Fi module 105 is in order to realize the function of Wi-Fi online.Wherein, the effect of described analog switch 102 is that switching described storage device 100 is connected with described micro SD card interface 103 with described Wi-Fi module 105.Described micro SD card interface 103 is the SDIO interface with micro SD card interface sheet metal, and described SDIO interface is a kind of Peripheral Interface defined in SD standard, and it can realize the function of an extension device.
In the present embodiment, as shown in Figure 1, described micro SD card interface 103 be one with the micro SD card standard interface of the standard micro SD draw-in groove adaptation of mobile phone, described storage device 100 is for realizing memory function, it comprises the storage control 110 be connected with described analog switch 102, and the memory cell 101 be connected with described storage control 110.Described Wi-Fi module 105 comprises the Wi-Fi chip 106 be connected with described analog switch 102 and the Wi-Fi built-in aerial 104 be connected with described Wi-Fi chip 106.
Preferably, because existing Wi-Fi uses the frequency range of 2.4GHz or 5GHz, so very little needed for the dimensional space of Wi-Fi built-in aerial 104, and along with the renewal of Wi-Fi technology and development, Wi-Fi chip 106 size is also more and more less, in standard micro SD card, thus puts down the Wi-Fi module 105 connected and composed by Wi-Fi built-in aerial 104 and Wi-Fi chip 106 do not have problem.
Such as, for the Wi-Fi built-in aerial of 2.4GHz, ceramic Wi-Fi built-in aerial can accomplish 2.0mm × 1.2mm, and the antenna space that required Wi-Fi module takies is at about 4mm × 3mm; And the Wi-Fi built-in aerial of 5GHz due to frequency range higher, so its antenna body size is less, the antenna space taken is thus then less.If the Wi-Fi built-in aerial of wherein said 5GHz is for saving cost, described Wi-Fi built-in aerial can be a printed antenna, described printed antenna directly draws copper cash on SD casing clamping body, and the antenna space shared by printed antenna is more slightly bigger than ceramic antenna, at about 4mm × 6mm.Micro SD card size is 15mmx11mm, according to above data, no matter adopts which kind of Wi-Fi built-in aerial all can put into micro SD card, and adopts which kind of built-in aerial can depending on concrete actual conditions.
In the present embodiment, as shown in Figure 2, described micro SD card interface 103 comprises and sets gradually pin 1 pin 411, pin 2 pin 412, pin 3 pin 413, pin 4 pin 414, pin 5 pin 415, pin 6 pin 416, pin 7 pin 417, pin 8 pin 418 described micro SD card interface 103 structural representation; Described micro SD card pinout is as shown in table 1; Described pin 1 pin 411 is the 2nd data wire pin, pin 2 pin 412 is the 3rd data wire pin, pin 3 pin 413 is command pin, pin 4 pin 414 is power pins, pin 5 pin 415 is clock pins, pin 6 pin 416 is grounding pin, pin 7 pin 417 is the 0th data wire pin, pin 8 pin 418 is the 1st data wire pin.

Based on above-described embodiment, present invention also offers a kind of mobile phone, as shown in Figure 2, described mobile phone comprises machine body 200 on the other hand, be arranged on the cell phone mainboard 122 of in mobile phone body 200, micro SD draw-in groove 107, baseband chip 108, LCD display 109 that described cell phone mainboard 122 is arranged.
Described micro SD draw-in groove 107, baseband chip 108, LCD display 109 connect successively.The mobile phone of the present embodiment, as shown in Figure 2, it also comprises the micro SD card 111 with Wi-Fi function described in above-described embodiment, and described micro SD card 111 is arranged on described micro SD draw-in groove 107 by the grafting of SDIO interface.And described micro SD draw-in groove 107 is a standard micro SD draw-in groove.
The present invention will be further described below to lift specific embodiment; After user inserts the micro SD draw-in groove 107 of mobile phone the micro SD card 111 of band Wi-Fi function, mobile phone base band chip 108 detects micro SD card, and acquiescence enters store status.When user needs with mobile phone Wi-Fi online according to selection, then need the Wi-Fi function of user manually opened micro SD card, after baseband chip 108 receives the signal opening Wi-Fi, this signal can be added, because command pin can self-defined transferring content on the order pin and pin 3 pin 413 of micro SD card 111.
After micro SD snaps fit onto mentioned order, by analog switch 102 switching interface being positioned at micro SD card, namely interface can be switched to Wi-Fi module 105 from storage device 100.And have supply pin and pin 3 pin 414 in pin due to micro SD card therefore can power supply is to start Wi-Fi module 105 thus, after Wi-Fi module 105 starts, mobile phone can realize the function of Wi-Fi online.
Separately, when user does not need mobile phone Wi-Fi to surf the Net, then need the Wi-Fi function of user's manual-lock micro SD card, after baseband chip 108 receives the signal of closing Wi-Fi, can add this signal on micro SD card command pin and pin 3 pin 413, after this order is received in micro SD clamping, analog switch 102 can according to order switching interface, make interface again be switched to storage device, so far conventional store status got back to again by micro SD card.
Relevant information in the present embodiment said process, all shows on LCD of mobile phone display screen 109, and user can obtain relevant information according to the prompting in LCD display 109 and carry out corresponding operating.
In sum, the present invention, by adding analog switch and Wi-Fi chip and Wi-Fi built-in aerial in the mobile phone micro SD card of standard, makes micro SD card not only possess memory function, also has Wi-Fi function, and can switch back and forth between two kinds of functions.And method of operation of the present invention is simple and practical, conveniently there is user's selectivity of demand to buy, carried out the application of extended mobile phone by annex, increase cost can not to again mobile phone itself.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection range that all should belong to claims of the present invention.
