Preferably, described upper exterior surface is provided with button.
Preferably, described capacitance contact board is fixed in the board slot of upper interior surface.
Preferably, described enclosure is fixed with a keypad, and described button is connected with keypad signal.
Preferably, described keypad is connected with described processor signal by general-purpose interface.
Preferably, described capacitance contact board is connected with described processor signal with the shared same described general-purpose interface of described keypad.
Preferably, capacitance touching control region is corresponding with the position of capacitance contact board, and distance is 0.5～2.0mm.
The beneficial effects of the utility model are that, by capacitance touch region and button are set on projector, the function of replacement mouse, makes projector functions more powerful.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the upper cover schematic diagram of the projector of a kind of capacitor touch pad of the utility model;
Fig. 2 is the sectional structure chart of the projector of a kind of capacitor touch pad of the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only 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 obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Projector of the present utility model comprises shell and is arranged on the processor of enclosure, and the surface of described shell is provided with capacitance touching control region 2, and its inside is provided with capacitance contact board 3, and capacitance contact board 3 is connected with processor signal.In the time that contacting with capacitance touching control region 2, user's finger can make electric capacity change, capacitance contact board 3 is known finger motion track by capacitive sensing, and send to processor with electric signal and process, correspondingly, the movement locus of finger is converted into the cursor movement track output in projection screen by processor, finally realizes the movement of cursor on projection screen.
In Fig. 1 and Fig. 2, projector case comprises upper cover 4 and lower cover 7.Button 1 is arranged at upper cover 4 outside surfaces of projector, and capacitance touching control region 2 is also arranged at upper cover 4 outside surfaces of projector.Touch pad 3 is positioned at the board slot of upper cover 4 inside surfaces.Keypad 5 is fixed in shell.On mainboard 6, be provided with processor.
When described projector work, user is in the time pushing button 1 arbitrary function key, and keypad 5 produces corresponding electric signal, and the processor reaching on mainboard 6 by general-purpose interface carries out corresponding calculation process, to realize corresponding function, as " determining ", " returning ", selection " menu " etc.; When user with finger on capacitance touch region 2 when slide, capacitance contact board 3 sends corresponding position electric signal to the processor on mainboard 6 by general-purpose interface and carries out corresponding calculation process, and projection is moved accordingly in the cursor of screen.By the function combination of button and capacitance touch, replace the left button right button of existing mouse and the function of mobile cursor.
In Fig. 1, button 1 comprise be with sagittate set direction key " on ", D score, " left side ", " right side ", middle acknowledgement key " OK ", and menu key " M " and realize the return key that returns to function.Button 1 in Fig. 1 is mechanical key, can be also the button such as capacitance touch, resistive touch.The function of button 1 can be expanded, and the mark of its function key, position can be also other design or combination.
In Fig. 2, capacitance contact board 3 is fixed in the board slot of upper cover 4 inside surfaces, preferably uses 3M glue and snap fit that capacitance contact board 3 is firmly close in board slot in the present embodiment, can certainly adopt other fixed form.Capacitance contact board 3 shares same general-purpose interface with keypad 5, and this general-purpose interface is connected to the processor on mainboard 6.Described general-purpose interface is PS2 interface in the present embodiment, can be also other types.
In preferred embodiment in the drawings, capacitance touching control region 2 is corresponding with the position of capacitance contact board 3, and distance is 1mm.
The foregoing is only 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., within all should being included in protection domain of the present utility model.
