Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 and Fig. 2, the embodiment of the invention comprises:
A kind of wireless pointer 1 comprises: nib 10, a shell 11, and said written 10 are processed by conductive material, and the part of said shell 11 can be processed by conductive material, said written 10 protruding being exposed to outside said the shell 11.Also comprise the circuit module 13 and signal transmission module 14 that are arranged in said the shell 11, said circuit module 13 links to each other with said written 10, and said circuit module 13 has signal amplifying function.
Specifically; Said circuit module 13 comprises control device of wireless 131, signal amplifying apparatus 132 and supply unit 133; Said signal amplifying apparatus 132 is connected between said control device of wireless 131 and said written 10, the power end of said control device of wireless 131, hold, the power end of said signal amplifying apparatus 132, hold with the power end of said supply unit 133, hold respectively and interconnect.Said control device of wireless 131 comprises wireless signal receiving end, communication signal transmitting terminal; Said communication signal transmitting terminal can send communication protocol signal and give the electronic equipment with touch controllable function; Said wireless signal receiving end can receive the infrared wireless signal that waits that the chip from the electronic equipment with touch controllable function emits; Then said wireless signal is sent to signal amplifying apparatus 132; Thereby reduced the connecting line that connects wireless pointer 1 and electronic equipment, realized the wireless telecommunications remote control, and realized that the mode of wireless telecommunications remote control is confined to this a kind of wireless signal transmission of infrared signal incessantly; Also can pass through bluetooth, WiFi wireless network signals such as (Wireless Fidelity, wireless compatibility authentications).
In order to make wireless pointer 1 receive the wireless signal of all angles more easily, in said shell 11, can be provided with signal transmission module 14, said shell 11 near said written 10 places can see through infrared grade for wireless signal simultaneously.Said signal transmission module 14 comprises a printing opacity polygon crystal 141, designs near said written 10 places.With the IR is example, and when IR was injected through said shell 11, through optically focused, the refraction action of said polygon crystal 141, the wireless signal receiving end of said control device of wireless 131 received infrared signal more easily; Said signal transmission module 14 also can comprise the reflecting piece 142 of a plurality of strips, is matrix type and is arranged in a shell 11 inside surfaces near said written 10 places.According to the thickness degree of said wireless pointer 1 and the placement angle of said circuit module 13, the arrangement scope and the mode of said reflecting piece 142 can be set as required.It still is example with the IR; Because the angle that said control device of wireless 13 receives infrared signal is within the specific limits; When the IR that surpasses this scope is injected through said shell 11; Through the reflection of said reflecting piece 142 and optically focused, the refraction of said polygon crystal 141; Thereby make IR be easy to received, and then enlarged the angle that wireless pointer 1 receives infrared signal, make itself and the also obviously raising of induction sensitivity of touch screen by the wireless signal receiving end of said control device of wireless 131.
In one embodiment, see also Fig. 1, said signal amplifying apparatus 132 comprises that a signal amplifies chip, all chips with signal amplifying function all can, chip max232 for example.Said signal amplifies chip and comprises two input ends and two output terminals; One of them input end in1 is connected with the output terminal of said control device of wireless 131; Another input end in2 is with after said input end in1 links to each other, and the output terminal with said control device of wireless 131 is connected again; An output terminal out1 is connected with said written 10, and out2 is unsettled for another output terminal.In another embodiment, see also Fig. 2, the output terminal out1 that said signal amplifies chip is connected with said written 10, and another output terminal out2 is connected with the inside surface of said shell 11.
Following mask body place of matchmakers states the principle of work of wireless pointer 1: in embodiment one, the wireless signal that is received by said control device of wireless 131 is through behind the said signal amplifying apparatus 132, and its amplitude is exaggerated.The signal output waveform figure of said wireless pointer 1; See also Fig. 3, the amplitude that gets into the wireless signal of said signal amplifying apparatus 132 is u, and the amplitude of the infrared signal behind the said signal amplifying apparatus 132 of process is U; The amplitude of said wireless signal obviously increases, and the screen that is easier to be touched is responded to.In embodiment two; The wireless signal that is received by said control device of wireless 131 is transferred to said signal amplifying apparatus 132 through an input channel of said signal amplifying apparatus 132; Be transferred to said signal amplifying apparatus 132 through another input channel; Through behind the said signal amplifying apparatus 132, the wireless signal of an input channel is amplified by forward, and the wireless signal of another input channel is reversed amplification; This moment, wireless signal promptly formed wireless differential signal, and said its amplitude of wireless differential signal is exaggerated.The signal output waveform figure of said wireless pointer 1; See also Fig. 4, the wireless differential signal a of the output terminal output of said signal amplifying apparatus 132 and the wireless differential signal b of another output terminal output are in the opposite direction, and amplitude equates; Amplitude with wireless differential signal b is with reference to zero potential; After wireless differential signal a and wireless differential signal b subtracted each other, its amplitude V was the twice of wireless differential signal a (wireless differential signal b) amplitude, thereby the signal amplitude that said written 10 places are obtained is obviously amplified; Said written 10 also obviously improve with the induction sensitivity of touch-screen, are very easy to using and operating of user.
Power end at said control device of wireless 131 and said signal amplifying apparatus 132 is connected with supply unit 133 with the ground end; Said supply unit 133 comprises battery and charging equipment (not indicating among the figure); Said battery can be a rechargeable battery; Also can be super capacitor, said charging equipment be said battery charge, and said wireless pointer 1 also can be through charging in the groove that inserts electronic equipment.Also be provided with a screen layer 12 said shell 11 outsides, processed by insulating material, finger reaches the electromagnetic interference (EMI) of the wireless pointer 1 of outer bound pair to the quantity of electric charge influence of wireless pointer 1 during the maskable operation.
The present invention is simple in structure, can receive infraredly to wait wireless signal transmission and send communication protocol signal, thereby and have and realize the wireless telecommunications remote control between the writing function display terminal of touch.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes instructions of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
