Embodiment
The embodiment of the invention provides a kind of Bluetooth adapter and Bluetooth communication system, in order to realize the expansion of Bluetooth adapter external interface, makes more equipment pass through Bluetooth adapter and links to each other with another equipment.
A kind of Bluetooth adapter with the female head of USB that the embodiment of the invention provides makes Bluetooth adapter behind the USB port that inserts computer, still can connect other USB interface equipment, offers convenience for the user uses.
Referring to Fig. 2, a kind of Bluetooth adapter that the embodiment of the invention provides comprises the bluetooth module 11 and external interface 13 of realizing Bluetooth function, and this Bluetooth adapter also comprises:
Be connected in the interconnecting module 12 between said bluetooth module 11 and the external interface 13;
Said external interface comprises two interfaces at least, and each interface is through carrying out the signal transmission between said interconnecting module 12 and said bluetooth module and/or other interface.
Preferably, said external interface 13 comprises:
General-purpose serial bus USB public access mouth and USB maternal interface.
The Bluetooth adapter that the embodiment of the invention provides has added the female head of USB on the basis of common Bluetooth adapter, on common adapter circuit plate, increase power line, is used to connect public head of the USB that inserts the PC end and the corresponding power interface of the female head of the USB that increases; And, so just can make Bluetooth adapter behind the USB port that inserts computer, still can connect other USB interface equipment with public head of USB and the corresponding data-interface of USB mother head that the PC end is inserted in two data wires connections.
Preferably, said interconnecting module 12 is usb hub (HUB).
Preferably, said USB HUB is connected between said bluetooth module and the USB public access mouth, and this USBHUB also links to each other with the USB maternal interface.
Preferably, said USB HUB is connected with one or more USB maternal interfaces.
Said USB HUB is the USB HUB of one tunnel input, two-way output; By said USB public access mouth input signal, and export to said bluetooth module 11 and/or said one or more USB maternal interface.
Preferably, said USB HUB is connected with two USB maternal interfaces, said USB HUB be one the tunnel import three the tunnel output USB HUB; By said USB public access mouth input signal, and export to said bluetooth module 11 and/or said two USB maternal interfaces one of them or all.
USB HUB described in the embodiment of the invention is the hub of USB interface.USB HUB is a kind ofly can a USB interface be expanded to a plurality of (being generally 4), and the device that these interfaces are used simultaneously.
USB HUB can connect computer desk lamp, computer fan, MP3, USB flash disk, recording pen, digital camera or the like equipment.Can a USB interface be extended to a plurality of USB interfaces that work alone, each power supply is up to 500MA.
In the embodiment of the invention, on the original architecture basics of Bluetooth adapter, increase a USB HUB module; This module is a present very common usb hub, and the chip of USB HUB is arranged above, and effect can become one road USB input USB output of multichannel exactly; For example; Referring to Fig. 3, can be the output of two-way, the transmission of control data.One tunnel output still is connected with bluetooth module, and another road output is received on the USB maternal interface.
Particularly, referring to Fig. 4, the female head of USB does not need extra setting; The female head of the USB of computer picks out four lines, through the public interface of the USB of Bluetooth adapter, is connected on the USBHUB that carries in the Bluetooth adapter; USB HUB becomes one tunnel input the output of two-way; Wherein one tunnel output is still received on the bluetooth module, and directly receive on the USB maternal interface of Bluetooth adapter on another road, and then it is just passable to be connected to other equipment.
The effect of the USB interface expansion of Bluetooth adapter is realized by USB HUB module.USB HUB in the embodiment of the invention can connect a plurality of USB maternal interfaces, as long as make one tunnel input to USB HUB module, the three tunnel or four the tunnel export and to get final product, this at present on the market USB HUB chip all can realize.
But the quantity of the USB maternal interface of connection need be taken into account other factors, and for example: Bluetooth adapter is generally all very little of to be convenient for carrying, and is almost big with a USB flash disk usually, may influence size if a plurality of USB maternal interfaces are installed.In addition, if connect a plurality of USB maternal interfaces, each USB maternal interface all connects other USB device, may bring the problem of electricity shortage, and the function that might influence bluetooth module realizes.
Referring to Fig. 5, connect the Bluetooth adapter structural representation of two USB maternal interfaces for USB HUB.
A kind of Bluetooth communication system that the embodiment of the invention provides comprises bluetooth equipment, also comprises above-mentioned Bluetooth adapter.
In sum; When the USB device that the embodiment of the invention makes computer connect is a lot; Bluetooth adapter still can connect other USB interface equipment behind the USB port that inserts computer, also can when the public head of the USB of Bluetooth adapter breaks down, connect Bluetooth adapter through the female head of USB.Transfer of data and the function of Bluetooth adapter own between public head of USB and the female head of USB also used.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, belong within the scope of claim of the present invention and equivalent technologies thereof if of the present invention these are revised with modification, then the present invention also is intended to comprise these changes and modification interior.
