Wireless device
View Patent ↗The present invention discloses a wireless device. The wireless device includes a housing, formed by a metal material, a wireless module disposed inside the housing, and an antenna, disposed outside the housing, coupled to the wireless module via a external socket interface disposed on the housing, for transmitting and receiving signals corresponding to the wireless module.
1. A wireless device, comprising:
a housing, formed by a metal material;
a wireless module, disposed inside the housing;
an external socket interface, disposed on the housing; and
an antenna, disposed outside the housing, coupled to the external socket interface for transmitting and receiving signals corresponding to the wireless module; wherein the external socket interface is a USB (Universal Serial Bus) port, and a power supply pin Vcc of the USB port is electrically connected to a signal trace of the antenna, and the power supply pin Vcc of the USB port is physically connected to the wireless module, and the USB port is coupled to a flash memory module which is powered by the power supply pin Vcc via a first RF choke circuit.
2. The wireless device of claim 1 , wherein the metal material is an aluminum alloy.
3. The wireless device of claim 1 , wherein the metal material generates a shielding effect on the signals of the wireless module.
4. The wireless device of claim 1 , wherein the wireless module is a Bluetooth module, a Wi-Fi module, a 3G (Third Generation) mobile communication module or a GPS (Global Positioning System) module.
5. The wireless device of claim 1 , wherein the antenna is coupled to the wireless module via the external socket interface in a pluggable manner.
6. The wireless device of claim 1 , wherein the wireless device further comprises:
a second RF choke circuit, coupled between the power supply pin and a power management circuit of the wireless device, for inhibiting the signals of the wireless module from entering the power management circuit via the power supply pin; and
a second DC block circuit, coupled between the power supply pin and the wireless module, for inhibiting a DC power supplied by the power management circuit from entering the wireless module via the power supply pin.
7. The wireless device of claim 1 , wherein a first DC block circuit is disposed in the antenna, coupled between the signal trace and the power supply pin, for inhibiting a DC power supplied by a power management circuit of the wireless device from entering a ground pin of the antenna.
