Abstract
The invention discloses an MHL cable and an electronic device. The MHL cable comprises a wire group which comprises a USB signal wire and an MHL signal wire. A problem that the MHL cable cannot realize MHL communication and USB communication simultaneously is solved by the MHL cable.
Description
Technical field
The present invention relates to electronic technology field, particularly a kind of MHL cable and a kind of electronic equipment.
Background technology
Mobile terminal high-definition audio and video standard interface MHL, when communicating, calls transmitting terminal the equipment of output sound video, and the equipment that receives audio frequency and video is called to receiving terminal, and transmitting terminal is connected by MHL cable with receiving terminal.
Present MHL cable had both been supported MHL communication, also support usb communication, but MHL communication and usb communication share a passage, cause existing MHL cable can not carry out MHL communication and usb communication simultaneously, when needs carry out MHL communication or usb communication, need switch and could realize; If both needed to carry out MHL communication, when receiving terminal needs again to host sending end transmission of audio signal, can only add in addition audio cable and realize audio collection passback, the cable increasing has like this increased cost on foot, also increase the complexity of operation, reduced the stability of system, and visually not attractive in appearance yet.
Summary of the invention
The invention provides a kind of MHL cable and a kind of electronic equipment, to solve MHL cable, can not realize the problem of MHL communication and usb communication simultaneously.
The invention provides a kind of MHL cable, described MHL cable comprises line group, and described line group comprises usb signal line and MHL holding wire.
Preferably, the outside of described line group is coated with aluminium foil.
Preferably, described MHL cable further comprises screen and insulating barrier; Wherein: described screen is coated on the outside of described aluminium foil, described insulating barrier is coated on the outside of described screen.
Preferably, described insulating barrier is plastic insulating layer.
Preferably, outside each coated one deck screen of described MHL holding wire and/or usb signal line.
Preferably, described MHL cable further comprises two interfaces, and one of them interface is HDMI interface, and another interface is USB3.0 interface or the above interface of USB3.0.
Preferably, in the space that described usb signal line and MHL holding wire surround, be filled with article shaped.
Preferably, described MHL holding wire comprises: voltage signal line, control signal wire, positive/negative difference video-audio signal line and earth connection.
Preferably, described usb signal line comprises: positive/negative differential signal line.
The present invention also provides a kind of electronic equipment, and described electronic equipment comprises: MHL cable as above.
The beneficial effect of the embodiment of the present invention is: MHL cable is integrated usb signal line and MHL holding wire, make MHL cable possess MHL passage and USB passage simultaneously, make MHL cable to carry out usb communication communicates by letter with MHL simultaneously, reduce the cost of extra increase USB cable, improved the stability of MHL cable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of MHL cable of one embodiment of the invention;
Fig. 2 is the profile of a kind of MHL cable of one embodiment of the invention;
Fig. 3 is the structure chart of a kind of electronic equipment of one embodiment of the invention.
Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
