[summary of the invention]
Fundamental purpose of the present utility model solves defective of the prior art exactly, and a kind of electronic teacher pointer is provided, make the speaker can be in the classroom multimedia courseware in the anywhere operating computer.
A time purpose of the present utility model just provides a kind of electronic teacher pointer, makes the speaker can control the demonstration effects such as volume, brightness of multimedia presentation system anywhere.
For achieving the above object, the utility model proposes a kind of electronic teacher pointer, comprise teacher's pointer bar and the laser delivery 6 that is fixed thereon, also comprise wireless mouse, described wireless mouse comprises the direction tracking module, mousebutton 13, control module and wireless transmitter module, described direction tracking module and mousebutton 13 are positioned at teacher's pointer bar surface, described control module and wireless transmitter module are positioned at teacher's pointer bar inside, described direction tracking module, the operation signal of mousebutton 13 inputs to control module, exports wireless transmitter module to and launch after the control module treatment conversion.
Described direction tracking module comprises the mouse tracking ball 10 or first photoelectrical position sensor, and described mouse tracking ball 10 is positioned at the upper surface of teacher's pointer bar, and described first photoelectrical position sensor is positioned at the lower surface of teacher's pointer bar.
Utilize electronic teacher pointer on demonstration screen/plate, to paint for convenience, described direction tracking module also comprises second photoelectrical position sensor 1, be positioned at the front end of teacher's pointer bar, described second photoelectrical position sensor 1 is connected in parallel to control module with mouse tracking ball 10, and the operation signal of second photoelectrical position sensor 1 or mouse tracking ball 10 exports wireless transmitter module to and launches after control module is handled.
The utility model can also comprise the wireless receiving module that is connected with computer.This receiver module can comprise the bluetooth PC card and the Bluetooth antenna of USB interface.Described wireless transmitter module can be the Bluetooth transmission module.
As further improvement of the utility model, also comprise function operating key 8, be used to control multimedia presentation system.
Preferably, described function operating key 8 can be four or six, evenly be positioned at mouse tracking ball 10 around.
Further improve as of the present utility model, also comprise laser instrument starting switch 2, be used for opening or close laser according to concrete applicable cases.
The beneficial effects of the utility model are: 1) speaker can carry out computermatic operation and can use electronic teacher pointer at an arbitrary position again the speech content, is not subjected to the restriction of computer placement location.The utility model with laser pointer and wireless mouse in conjunction with design, both realized the deixis of laser pointer, realized the function that computer mouse can be realized again, and be handheld device, need not to contact, also need not special-purpose electronic whiteboard, just can be implemented in the drawing of writing on common blank even the wall by the operation multimedia computer with any desktop, make effective scope of activities of speaker bigger, strengthened the effect of giving lessons.2) effects such as the volume of the anywhere control multimedia presentation system of function operating key 8 in the classroom that the speaker can be by electronic teacher pointer, brightness make things convenient for the speaker to use.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.

Fig. 3 represents the wireless receiving module synoptic diagram of a kind of embodiment of the utility model.
[embodiment]
Be illustrated in figure 1 as best embodiment of the present utility model, the electronic teacher pointer global shape is the shape that is easy to grasped, laser delivery 6 is positioned at the front end of electronic teacher pointer, also comprises laser instrument starting switch 2, is positioned at electronic teacher pointer and is easy to the position that finger touch arrives.The direction tracking module of present embodiment comprises mouse tracking ball 10 and photoelectrical position sensor 1, and photoelectrical position sensor 1 is positioned at the front end or the lower end of electronic teacher pointer, and mouse tracking ball 10 is positioned at the position that electronic teacher pointer is convenient to finger presses.Mousebutton 13 is positioned at according to ergonomics and is easy to the position that forefinger is pushed, and can be defined as by driver to be left mouse button or right mouse button, generally mousebutton 13 is defined as left mouse button.Function operating key 8 has four, evenly be positioned at mousebutton 13 around, can be defined as the function key of various needs by driver, for example regulate volume, regulate the brightness size, function such as page turning up and down.In the present embodiment four function operating keys are defined as brightness and increase that switch, brightness reduce switch, volume increases switch, volume down P cock.Also comprise battery case 4 and power switch 12, be positioned at the rear portion of electronic teacher pointer.The signal processing circuit of electronic teacher pointer is positioned at the inside of electronic teacher pointer, and the annexation of it and each parts as shown in Figure 2.Mouse tracking ball 10 comprise tracking ball interface circuit-X, tracking ball interface circuit-Y, tracking ball depress the monitoring and tracking ball; The optoelectronic position sensing module comprises optical mouse interface circuit-X, optical mouse interface circuit-Y, photoelectrical position sensor; Control module is microprocessor and peripheral circuit thereof; Mouse tracking ball 10 links to each other with microprocessor with the optoelectronic position sensing module; Drive circuit for laser, laser instrument starting switch, brightness increase switch, brightness and reduce that switch, volume increase switch, the volume down P cock also links to each other with microprocessor respectively with the Bluetooth transmission module.
During use, at first the energized switch 12, and electronic teacher pointer enters duty, press laser instrument starting switch 2 under powering state, then drive circuit for laser work, and laser delivery 6 will outgoing laser beam.This partial circuit and other parts work alone.Mouse tracking ball 10 and photoelectrical position sensor 1 have all been realized the function of computer mouse, being equivalent to mouse roller when mouse tracking ball is depressed depresses, left mouse button depressing is equivalent to the left button of computer mouse and depresses, use when being used for feature operation, writing and drawing, and double click operation is provided, its function is identical with the mouse function of computer own.Such as, after the operation drawing board program, cooperate left mouse button, with photoelectrical position sensor 1 on the table, on the wall or just can draw a picture on hand.Two function operating keys can be finished the adjusting of the volume of computer sound, and two other function operating key can be finished the adjusting of the brightness size of demonstration.By driver software, its function can also be redefined and be other function keys on the computor-keyboard.After the user has operated mousebutton or function operating key, receive button or sensor signal by signal processing circuit, delivering to the Bluetooth transmission module behind the coding in microprocessor launches, the bluetooth receiver module that is connected on the computer is received these coded signals, transfer to the operation that driver is interpreted as mouse and function operating key, as shown in Figure 3.
The difference of second kind of embodiment of the present utility model and first kind of embodiment is that the direction tracking module is in mouse tracking ball 10 and the photoelectrical position sensor 1.
