Abstract
The utility model relates to a USB concentrator, which can support the playing back of sound source of media and charging, in addition to expanding connection of USB ports with peripheries. The utility model comprises a USB host unit, a plurality of USB expansion units, a USB controller connected between the USB host unit and the USB expansion units, and an external power supply. Wherein, at least the bus of a first USB expansion unit can support outputting of a sound source, and a logic switch is connected between the USB expansion unit and the USB controller. Another end of the logic switch is connected with the USB host unit or the power-supplying end of the external power supply. When the first USB expansion unit is connected with for example a MP3 or other sound media, the logic switch will detect the signal and cut off the data transmission of the first USB expansion unit, and charge and play back music for the connected unit through the USB host unit or the power supplying from the external power supply, and a user can listen to the music just by an external loudspeaker or earphones.
Description
Technical field
The utility model relates to a kind of usb hub, and is particularly a kind of except that in order to expand USB interface and external device (ED) is connected, more the hub of the function of the broadcast of support media source of sound and charging.
Background technology
General serial formula bus (Universal Serial Bus abbreviates USB as) has been widely used in the standard of information products as the interface system of communication connection.By USB interface, the device of each periphery can be connected to main frame via this usb bus, needs with different size connector and the online problem of main frame to solve previous various periphery.In addition, USB has the functional characteristic of plug and play, that is when installing or removing the USB peripheral device, the main frame of need not shutting down computer, also install driver separately.
In order to expand USB interface, connect a plurality of USB expansion units with a usb host unit by a USB controller usually, and integrated and become a hub.Traditional usb hub does not provide other support except that having extended function, for example the output of source of sound such as MP3 or Media Player and its purposes is restricted.
The utility model content
The purpose of this utility model is to provide a kind of usb hub of novelty, makes it except that expanding USB interface and external device (ED) is connected, more the function of the broadcast of support media source of sound and charging.Comprise that a usb host unit, a plurality of USB expansion unit, are connected in USB controller between usb host unit and the USB expansion unit, an and external power supply, wherein, the bus of at least the one USB expansion unit has the support of source of sound output, and be connected with a logic switch between this USB expansion unit and USB controller, the end in addition of this logic switch then is connected in the power source supply end of usb host unit or external power supply; Thus, when a USB expansion unit and for example MP3 or other sound source medium device are online, this logic switch can detect signal and cut off the transfer of data work that a USB expansion unit is carried out, and this online device is charged and the output of music by the power supply supply of usb host unit or external power supply, the user is as long as external loudspeaker or earphone can be listened to.
In addition, this usb hub can serve as the pedestal of MP3 Player, and at usb host unit and computer interconnection state or have only with external power supply when online, provides this MP3 Player or Media Player to carry out charging work.

Embodiment
As shown in Figure 1, usb hub of the present utility model comprises that mainly a usb host unit 1, a plurality of USB expansion unit 20,21,22,23, are connected in USB controller 3 between usb host unit 1 and the USB expansion unit 20,21,22,23, an and external power supply 4; Wherein,
Usb host unit 1 uses for peripheral device or equipment to support other USB expansion unit 20,21,22,23 in order to online 10 with the system of for example main frame;
The bus of at least the one USB expansion unit 20 has the support of source of sound output, as shown in Figure 1, the link that has Audio L and Audio R in the one USB expansion unit 20, and be connected with a logic switch 5 between a USB expansion unit 20 and USB controller 3, the end in addition of this logic switch 5 then is connected in the power source supply end of usb host unit 1 or external power supply 4;
Thus, when a USB expansion unit 20 and the device of for example MP3 Player6 or other tool sound source medium are online, except that can transmit or the access data, if want playing back music, this logic switch 5 can detect signal and cut off the data work that a USB expansion unit 20 is carried out, and the power supply supply of passing through the usb host unit 1 that connected or external power supply 4 is charged to this online device 6 and the output of music, and the user is as long as external loudspeaker or earphone can be listened to.
The concrete enforcement framework of the utility model can be joined shown in Figure 2, this usb hub has a shell 7 that comprises all above-mentioned composition assemblies, as for usb host unit 1 and 21,22 of each expansion units be distributed in this shell 7 around, a particularly aforementioned USB expansion unit 20 is located at the end face 70 of shell 7, for example make device such as MP3 Player6 or Media Player uprightly mode peg graft, and this shell 7 is used (as shown in Figure 3) as a pedestal.
In addition, the precalculated position of this shell 7 is provided with one and connects first socket 71 of external power supply 4 and second socket 72 of an external earphone or loudspeaker 8, and this second socket 72 is promptly online with the source of sound output of an above-mentioned USB expansion unit 20.
Above-mentioned specific embodiment is only in order to explanation the utility model, and non-limiting the utility model.
