Description
Technical field
The utility model relates to electronic technology field, refers to especially a kind of laser pointer.
Background technology
Along with the development of electronic technology, electronic instruction is popularized widely.Existing electronic teacher pointer mainly comprises laser shot-light and page turning key, realizes remote indication and the function of page turning up and down.But existing teacher's pointer need to be by mouse when pictures such as enclosing circle, emphasis sign operates, and the speaker need to go to the dais and just can finish, and has affected the continuity of lecture.
The utility model content
The utility model proposes a kind of laser pointer, solved the problem that to finish the operation of drawing in the prior art by mouse.
The technical solution of the utility model is achieved in that
A kind of laser pointer, comprise: laser shot-light, button, wireless module, touch pad, controller and lithium battery, described laser shot-light is connected to described lithium battery, described button is connected to described controller, described touch pad is connected to described controller, described controller is connected to described wireless module, and described wireless module is connected to computing machine by wireless network.
Alternatively, described laser shot-light is the red laser shot-light.
Alternatively, described wireless module is bluetooth module.
Alternatively, described controller is single-chip microcomputer.
Alternatively, described controller is dsp processor.
Alternatively, described controller is arm processor.
The beneficial effects of the utility model are: laser pointer can realize the drawing operated from a distance of function, and make speaker's demonstration more smooth and easy, and circuit is simple, easy to operate.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the control block diagram of the utility model laser pointer.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, laser pointer of the present utility model comprises: laser shot-light 10, button 20, wireless module 30, touch pad 40, controller 50 and lithium battery 60; Laser shot-light 10 is connected to lithium battery, is used for remote indication, and for example laser shot-light 10 can be the red laser shot-light; Button 20 is connected to controller 50, is used for prompt operation, and a key triggers the picture function, and the quantity of button 20 also can be a plurality of; Touch pad 40 is connected to controller 50, after button 20 triggers the picture function, receives speaker's hand motion, and is converted into electric signal; Controller 50 can be single-chip microcomputer, dsp processor or arm processor, receives the instruction of button 20 and touch pad 40; Controller 50 is connected to wireless module 30, and wireless module 30 is connected to computing machine by wireless network, and for example wireless module 30 can be bluetooth module.
Laser pointer of the present utility model can realize the drawing operated from a distance of function make speaker's demonstration more smooth and easy, and circuit is simple, and is easy to operate.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
