Abstract

The invention discloses a wireless network card with a recording function, comprising a central processing unit, a microphone, a converter and a memory, wherein the central processing unit is used for compressing digital signals transmitted by the converter and then outputting to the memory for storage; the microphone is used for collecting analog sound signals outside the wireless network card and transmitting to the converter; and the converter is used for converting the analog sound signals collected by the microphone into digital signals and transmitting to the central processing unit. The above wireless network card can record external sound signals, and users can realize recording without carrying additional recording device.

Description

technical field [0001] The invention relates to the field of wireless network cards, in particular to a wireless network card with recording function. Background technique [0002] At present, wireless network cards are being used more and more, this is because: firstly, wireless network cards have universal interfaces to facilitate connection with computers, such as Universal Serial Bus (USB, Universal Serial Bus) interfaces; secondly, wireless network cards can Wireless service (GPRS, General Packet Radio Service), Code Division Multiple Access (CDMA, Code Division Multiple Access), Enhanced Data Rate for GSM Evolution (EDGE, Enhanced Data Rate for GSM Evolution) or 3G, etc. to access the Internet, as long as there is Where the signal of the mobile call terminal is covered, the wireless network card can be used to access the Internet. [0003] figure 1 It is a structural diagram of a wireless network card in the prior art, and the wireless network card includes: a centra...
