Abstract
Mobile phone wireless based on USB interface projector passes screen device, is related to electronic device data process field, including sequentially connected HDMI wirelessly turns VGA patchcord, the male to male adapter of VGA to female adapter, high-definition digital interface HDMI with screen device, mother HDMI；The one end of HDMI wirelessly with screen device is equipped with USB interface, pin end of the HDMI wirelessly with screen device is connect with the first female connector of mother HDMI to female adapter, mother HDMI connect the second female connector of female adapter with the high-definition digital interface HDMI pin end for turning VGA patchcord, the female connector that high-definition digital interface HDMI turns VGA patchcord is connect with the first pin end of the male to male adapter of VGA, the VGA female connector of the second pin end connection projector of the male to male adapter of VGA.So that the wireless screen transmission device of HDMI male connector interface is worked on the interface projector of VGA female, plays the waste heat of old-fashioned projector.
Description
Technical field
The utility model relates to electronic device data process fields more particularly to mobile phone wireless to pass screen teaching.
Background technique
Wireless screen transmission is to utilize WIFI(WLAN) screen of mobile phone or computer is shown on projector curtain
Out, which needs the support of wireless screen transmission equipment, and between 100-200 member, which uses the purchase cost of the equipment
HDMI interface, cost is far below computer and multimedia exhibition stand, but can not be connected with using the projector of VGA female interface.
The reason is that: the interface of wireless screen transmission device is HDMI interface at present, and the interface is in the intelligence produced in the recent period
TV includes using on projector.But have VGA(Video Graphics Array, Video Graphics Array) interface is without HDMI
The projector market ownership of (High Definition Multimedia Interface, high-definition digital interface) interface is remote
Much higher than the projector for being equipped with HDMI interface or built-in wireless connection device, most of existing projector in market is all the several years
Preceding configuration, most of not have HDMI interface, this just gives is caused by mobile phone+wireless screen transmission device (HDMI male connector) wireless display
Certain obstacle.It is crucial that by early-stage study, find the finished product HDMI that can be bought in the market turn VGA or
VGA turns HDMI patchcord, and wireless screen transmission device (HDMI male connector) can not be made to work normally the projector in VGA female interface
On.This just needs to carry out wireless screen transmission technology some selections or carries out some technological improvements to switching device.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of based on USB interface projector
Mobile phone wireless passes screen device, and the wireless screen transmission device of HDMI male connector interface is enable to work on the interface projector of VGA female.It opens up
The use scope of wide wireless screen transmission device, plays the waste heat of old-fashioned projector.
Purpose of the utility model is realized as follows: the mobile phone wireless based on USB interface projector passes screen device, including
It is male right that sequentially connected HDMI wirelessly turns VGA patchcord, VGA to female adapter, high-definition digital interface HDMI with screen device, mother HDMI
Revolve connector；The HDMI is wirelessly equipped with USB interface with one end of screen device, and the other end of the HDMI wirelessly with screen device is equipped with public access
Head, mother HDMI are equipped with the first female connector and the second female connector to female adapter, and high-definition digital interface HDMI turns VGA patchcord and is equipped with
Pin end and female connector, the male to male adapter of VGA are equipped with the first pin end and the second pin end；The HDMI is wirelessly the same as screen device
Pin end is connect with the first female connector of mother HDMI to female adapter, second female connector and high definition number of mother HDMI to female adapter
Word interface HDMI turns the pin end connection of VGA patchcord, and high-definition digital interface HDMI turns the female connector and VGA public affairs of VGA patchcord
The first pin end connection to revolution connector, the VGA female connector of the second pin end connection projector of the male to male adapter of VGA.
When operation, USB interface of the HDMI wirelessly with screen device is inserted on the USB interface of projector, to HDMI wirelessly with screen device
(iPazzPort Cast) power supply.By HDMI wirelessly with screen device, mother HDMI to female adapter, patchcord, the male to male switching of VGA
After head, projector connect, the signal source of projector selects HDMI, and projector occurs as soon as the interface of iPazzPort Cast.
Android system mobile phone is pushed by Miracast mode.By taking Android system mobile phone as an example, > network and connection is being arranged in millet mobile phone
Then > more connection type > Wireless Display > unlatching Wireless Displays click the mark of the iPazzPort_cast-****** of lower section
It can connect.Installation plays Powerpoint and plays the software of video on mobile phone, opens courseware, that is, implementable mobile phone teaching.
The beneficial effects of the utility model are:
(1) mobile phone directly is carried using teacher and carry out wireless screen transmission teaching, save the buying money of computer and multimedia exhibition stand
Gold.On the basis of having projector, it is not necessarily to computer, without multimedia exhibition stand.As long as being equipped with the nothing of one piece of 100 yuan or so cost
Line passes screen device, that is, mobile phone can be used to play the data such as PPT, broadcasting video and impart knowledge to students.The ground of education funds anxiety can be given
Area provides a solution of interactive mode teaching.
(2) use scope that mobile phone wireless passes screen has been expanded.Using current existing biography screen device, mobile phone can only be to having
The projector of HDMI interface or built-in wireless connection device carries out biography screen.Because of the wireless screen transmission that can be bought in the market
Device is HDMI interface, cannot be interconnected with the projector for the USB interface being equipped in present most of multi-media classrooms.In this way
Mobile phone wireless pass screen be just only used for it is some it is newly-built be equipped with the multi-media classroom of HDMI interface projector, and cannot be used for big
Measure the projector of old-fashioned USB interface.It can be used to HDMI interface projector and be used for VGA connect using the utility model switching
Mouth projector, the promotion prospect which has had.
(3) utilization rate of existing educational technology equipment is promoted.Although the school of many developed areas has purchased more high-grade
Teaching equipment, such as electronic whiteboard, the equipment such as projector that multi-media classroom was originally equipped with may be trapped on the shelf
State, to result in waste of resources.Mobile phone wireless, which passes screen device, can promote stand-by equipment in the case where spending very low cost
Utilization rate.
Electricity shortage in order to prevent, HDMI wirelessly connect mobile power source by USB interface with screen device.
Detailed description of the invention
Fig. 1 is the first structural schematic diagram of the utility model.
Fig. 2 is second of structural schematic diagram of the utility model.
