Falling into, such as such as the limitation of mouse action scope, the range of activity limiting teacher can only be near dais, nothing
Method is gone to and is gone exchange aspectant with student in student；In addition the curtain of common multimedia projection is to be only used for
The display of image and picture can not be write above drawing etc..
Therefore, we are in the practice of daily teaching, and that designs a kind of low cost can have wireless mobile
Mouse function, can simultaneously serve as wireless microphone, but also can write on projection screen multi-functional
Writing pencil.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of wireless writing pencil of multimedia screen, solves
Can destroy battery in prior art, Control of Voltage is unstable, exports the most considerable phenomenon, it is provided that Yi Zhongjie
Structure is simple, easy to use, simple to operate, the mouse function can with wireless mobile of low cost, simultaneously
Can be as wireless microphone, but also the wireless writing pencil of multimedia screen that can write on projection screen.
For solving the problems referred to above, this utility model adopts the following technical scheme that a kind of multimedia screen wireless hand
Write pen, including infrared writing pencil, computer camera, projector and curtain；Described infrared writing pencil
Front end is provided with nib；LED infrarede emitting diode it is provided with on described nib；Described computer shooting
Head can record the track of the infrared light spot that infrared writing pencil sends, writing pencil contact on curtain each time
Or the track drawing the produced infrared light of shifting all can be caught by computer camera；Described infrared writing pencil
On be provided with bluetooth wireless microphone；Wireless mouse left and right control key it is provided with on described infrared writing pencil.
Further, described wireless mouse left and right control key is provided with wireless transmitter.
Further, described bluetooth wireless microphone is provided with microphone.
Further, it is provided with updating device between described computer camera and infrared writing pencil.
Further, described wireless transmitter is provided with bluetooth module.
The effect of this utility model a kind of multimedia wireless writing pencil of screen is: when coming into operation, first,
The particularity of writing pencil is that it does not has ink, and its nib is a LED infrarede emitting diode, at pen
Any ink marks will not be left the when that point touching projection screen on screen, but can launch infrared immediately
Luminous point.The effect of computer camera is the track recording the infrared light spot that infrared writing pencil sends, each time hands
Write pen contact on screen or draw and move under the track of produced infrared light all can catch by computer camera
Come.By the electronic whiteboard software installed in computer, the track of photographic head institute recording spot is converted into electron plate
On the present projection screen of letter submitted to one's superior, bluetooth wireless microphone can expand the volume of teacher, controls about wireless mouse
Key can conveniently operate, and decreases inconvenience during operation mouse, and wireless transmitter transfers signals to computer and takes the photograph
As head, person's handwriting can be erased switching lantern slide when by updating device, and its simple in construction is easy to use,
Simple to operate, the mouse function can with wireless mobile of low cost, can simultaneously serve as wireless microphone,
But also can write on projection screen.
