Due to current mobile phone The data transmission rate of Wi-Fi used can theoretically reach up to 75 Mbps, but in practice it can generally reach about 10 Mbps. At the same time, the SD card rate conforming to SD2.0 can be up to 80 Mbps, so the bandwidth of the general analog switch is not Less than 100Mhz.
所述存储装置 100的作用可实现普通 micro SD卡的扩展存储功 能， 所述 Wi-Fi模块 105用以实现 Wi-Fi上网的功能。 其中， 所述模 拟开关 102的作用在于切换所述存储装置 100和所述 Wi-Fi模块 105 与所述 micro SD卡接口 103连接。 所述 micro SD卡接口 103为带有 micro SD卡接口金属片的 SDIO接口， 所述 SDIO接口为在 SD标准 上定义的一种外设接口， 其能实现延伸一个装置的功能。  The function of the storage device 100 can realize the extended storage function of the ordinary micro SD card, and the Wi-Fi module 105 is used to implement the Wi-Fi Internet access function. The function of the analog switch 102 is to switch the storage device 100 and the Wi-Fi module 105 to the micro SD card interface 103. The micro SD card interface 103 is an SDIO interface with a micro SD card interface metal piece, and the SDIO interface is a peripheral interface defined on the SD standard, which can realize the function of extending a device.
本实施例中， 如图 1所示， 所述 micro SD卡接口 103为一与手机 的标准 micro SD卡槽适配的 micro SD卡标准接口，所述存储装置 100 用于实现存储功能， 其包括与所述模拟开关 102 连接的存储控制器 110, 以及与所述存储控制器 110连接的存储单元 101。 所述 Wi-Fi 模块 105包括与所述模拟开关 102连接的 Wi-Fi芯片 106以及与所述 Wi-Fi芯片 106连接的 Wi-Fi内置天线 104。  In this embodiment, as shown in FIG. 1 , the micro SD card interface 103 is a micro SD card standard interface adapted to a standard micro SD card slot of the mobile phone, and the storage device 100 is configured to implement a storage function, including A memory controller 110 connected to the analog switch 102, and a memory unit 101 connected to the memory controller 110. The Wi-Fi module 105 includes a Wi-Fi chip 106 connected to the analog switch 102 and a Wi-Fi internal antenna 104 connected to the Wi-Fi chip 106.
较佳地 , 由于现行 Wi-Fi使用的是 2.4GHz或 5GHz的频段 , 所 以 Wi-Fi内置天线 104的尺寸空间所需很小， 且随着 Wi-Fi技术的更 新与发展， Wi-Fi芯片 106尺寸也越来越小， 因而在标准 micro SD卡 内放下由 Wi-Fi内置天线 104与 Wi-Fi芯片 106连接构成的 Wi-Fi模 块 105不会有问题。  Preferably, since the current Wi-Fi uses a frequency band of 2.4 GHz or 5 GHz, the size space of the Wi-Fi built-in antenna 104 is small, and with the update and development of Wi-Fi technology, the Wi-Fi chip The size of the 106 is also getting smaller and smaller, so that the Wi-Fi module 105 constructed by connecting the Wi-Fi internal antenna 104 and the Wi-Fi chip 106 in the standard micro SD card is not problematic.
例如， 针对 2.4GHz的 Wi-Fi内置天线， 陶瓷 Wi-Fi内置天线可 以做到 2.0mm 1.2mm , 所需 Wi-Fi模块占用的天线空间在 4mm 3mm左右； 而 5GHz的 Wi-Fi内置天线由于频段更高， 所以其天线本 体尺寸更小， 因而所需占用的天线空间则更小。 其中所述 5GHz的 Wi-Fi内置天线如果为节省成本， 所述 Wi-Fi内置天线可以为一印刷 天线， 所述印刷天线直接画铜线在 SD卡壳体上， 印刷天线所占用的 天线空间比陶瓷天线稍大一点， 在 4mm 6mm左右。 micro SD卡大 小为 15mmxl lmm, 根据以上数据可知， 无论采用何种 Wi-Fi内置天 线均能放入 micro SD卡中， 而采用何种内置天线可以视具体的实际 情况而定。 For example, for a 2.4GHz Wi-Fi internal antenna, the ceramic Wi-Fi internal antenna can be 2.0mm 1.2mm, and the required Wi-Fi module occupies 4mm of antenna space. The 5 GHz Wi-Fi internal antenna has a smaller frequency band, so the antenna body is smaller in size, and thus the required antenna space is smaller. Where the 5 GHz Wi-Fi internal antenna is cost-saving, the Wi-Fi internal antenna may be a printed antenna, and the printed antenna directly draws a copper wire on the SD card housing, and the antenna space occupied by the printed antenna The ceramic antenna is slightly larger, around 4mm 6mm. The size of the micro SD card is 15mmxl lmm. According to the above data, no matter which Wi-Fi internal antenna is used, it can be placed in the micro SD card. The built-in antenna can be determined according to the actual situation.

基于上述实施例， 本发明还提供了一种手机， 如图 2所示， 所述 手机包括一手机本体 200, 设置在手机本体内 200的手机主板 122, 在所述手机主板 122上设置的 micro SD卡槽 107、基带芯片 108、LCD 显示屏 109。  Based on the above embodiment, the present invention further provides a mobile phone. As shown in FIG. 2, the mobile phone includes a mobile phone body 200, a mobile phone motherboard 122 disposed in the mobile phone body 200, and a micro on the mobile phone motherboard 122. The SD card slot 107, the baseband chip 108, and the LCD display 109.
所述 micro SD卡槽 107、基带芯片 108、 LCD显示屏 109依次连 接。 本实施例的手机， 如图 2所示， 其还包括上述实施例所述的具有 Wi-Fi功能的 micro SD卡 111 , 所述 micro SD卡 111通过 SDIO接口 插接设置在所述 micro SD卡槽 107上。 而所述 micro SD卡槽 107为 一标准 micro SD卡槽。  The micro SD card slot 107, the baseband chip 108, and the LCD display screen 109 are sequentially connected. The mobile phone of this embodiment, as shown in FIG. 2, further includes a micro SD card 111 with a Wi-Fi function as described in the above embodiment, and the micro SD card 111 is inserted into the micro SD card through an SDIO interface. On the slot 107. The micro SD card slot 107 is a standard micro SD card slot.
以下举具体实施例对本发明做进一步说明； 当用户把带 Wi-Fi功 能的 micro SD卡 111插入手机的 micro SD卡槽 107后， 手机基带芯 片 108检测到 micro SD卡， 并默认进入存储状态。 当用户根据选择 需要用手机 Wi-Fi上网时,则需要用户手动开启 micro SD卡的 Wi-Fi 功能， 当基带芯片 108接收到开启 Wi-Fi的信号后， 会在 micro SD 卡 111的命令脚即 pin 3脚 413上加入这个信号， 因为命令引脚可以 自定义传输内容。  The present invention will be further described in the following embodiments; when the user inserts the Wi-Fi enabled micro SD card 111 into the micro SD card slot 107 of the mobile phone, the mobile phone baseband chip 108 detects the micro SD card and enters the storage state by default. When the user needs to use the mobile phone Wi-Fi to access the Internet according to the selection, the user needs to manually turn on the Wi-Fi function of the micro SD card. When the baseband chip 108 receives the signal to turn on the Wi-Fi, it will be on the command pin of the micro SD card 111. That is, this signal is added to the pin 3 pin 413 because the command pin can customize the transmission content.
当 micro SD卡接到上述命令后， 会由位于 micro SD卡内的模拟 开关 102切换接口， 即把接口从存储装置 100切换到 Wi-Fi模块 105 上。 而且由于 micro SD卡的引脚中有电源脚即 pin 3脚 414故可以由 此电源来启动 Wi-Fi模块 105 , 当 Wi-Fi模块 105启动后， 手机即可 实现 Wi-Fi上网的功能。 When the micro SD card is connected to the above command, the interface is switched by the analog switch 102 located in the micro SD card, that is, the interface is switched from the storage device 100 to the Wi-Fi module 105. on. Moreover, since the micro SD card has a power supply pin, that is, a pin 3 pin 414, the Wi-Fi module 105 can be activated by the power source. When the Wi-Fi module 105 is activated, the mobile phone can implement the Wi-Fi Internet access function.
另，当用户不需要手机 Wi-Fi上网时，则需要用户手动关闭 micro SD卡的 Wi-Fi功能， 当基带芯片 108接收到关闭 Wi-Fi的信号后， 会在 micro SD卡命令脚即 pin 3脚 413上加入这个信号， micro SD 卡接收该命令后，模拟开关 102会根据命令切换接口，使得接口重新 切换到存储装置， 至此 micro SD卡又回到常规存储状态。  In addition, when the user does not need to use the mobile phone Wi-Fi to access the Internet, the user needs to manually turn off the Wi-Fi function of the micro SD card. When the baseband chip 108 receives the signal to turn off the Wi-Fi, the micro SD card command pin is pinned. This signal is added to the 3-pin 413. After the micro SD card receives the command, the analog switch 102 switches the interface according to the command, so that the interface is switched back to the storage device, and the micro SD card returns to the normal storage state.
本实施例上述过程中的相关提示信息，均在手机 LCD显示屏 109 上显示， 用户可根据 LCD显示屏 109上的提示获取相关信息以及进 行相应操作。  The related prompt information in the above process of the embodiment is displayed on the LCD display 109 of the mobile phone, and the user can obtain relevant information according to the prompt on the LCD display 109 and perform corresponding operations.
综上所述， 本发明通过标准的手机 micro SD卡里加入模拟开关和 wi-fi芯片及 wi-fi内置天线， 使得 micro SD卡不仅具备存储功能， 还 具有 wi-fi功能， 而且可以在两种功能之间来回切换。 且本发明操作 方法简单实用， 方便有需求的用户选择性购买， 通过附件来扩展手机 的应用， 又不会给手机本身增加成本。  In summary, the present invention adds an analog switch and a wi-fi chip and a wi-fi internal antenna through a standard mobile micro SD card, so that the micro SD card not only has a storage function, but also has a wi-fi function, and can be used in two Switch back and forth between functions. Moreover, the operation method of the invention is simple and practical, and is convenient for users who need to purchase selectively, and expands the application of the mobile phone through the accessory, and does not increase the cost of the mobile phone itself.
