Abstract
The invention discloses an active type touch pen, which comprises a pen holder, wherein a pen tip is arranged at the front end of the pen holder; an excitation device is arranged in the pen holder; the pen tip is an elastic conductive pen tip; a pressure sensing unit and an amplifier are arranged in the pen holder, the pressure sensing unit is tightly attached to the elastic conductive pen tip, and the pressure sensing unit, the amplifier and the excitation device are sequentially and serially connected; the pressure sensing unit is used for sensing the pressure change of the elastic conductive pen tip, and converting the pressure change into a voltage signal; the amplifier is used for amplifying the voltage signal, and sending the amplified voltage signal to the excitation device. The active type touch pen has the advantage that in the writing process, the elastic conductive pen tip is deformed along with the pressure change of the wiring, the pressure change is converted into the voltage change, the voltage change is finally transferred to the excitation device, the excitation device is used for transmitting an excitation signal with corresponding intensity to the touch screen according to the voltage change, and the touch screen senses the change of writing force, so that the display of the touch screen is guaranteed to truly reflect the input of the user, and improve the human-machine interaction accuracy.
Description
Technical field
The present invention relates to a kind of active pointer.
Background technology
Along with the development of science and technology, touch technology has been widely used in the multimedia equipments such as notebook computer, panel computer, mobile phone.When finger touch capacitance plate, due to human body electric field, finger and workplace form a coupling capacitance, so finger walks a very little electric current, this is equivalent to the change of touch point place electrode capacitance, and the touch chip of touch-screen can determine the position of touch point by the change of detecting electrode electric capacity.Except coming, except touch control operation touch-screen, felt pen can also be used to carry out operating of contacts by finger.
Pointer is generally divided into passive type pointer and active pointer.The principle of operation of passive type pointer is similar to finger, is to adopt the finger of the nib and user with conductive characteristic to be connected, and is equivalent to the aid for extending finger.Active pointer then can launch pumping signal by inner exciting bank, and in order to change the electric field at touch point place, thus change the electrode capacitance at touch point place, touch chip can determine the position of touch point by the change of detecting electrode electric capacity.
At present, existing active pointer cannot the operating force of perception user, thus causes the display translation of the input of user and touch-screen to there is larger deviation, and the precision comparison of man-machine interaction is low.
Summary of the invention
The object of the present invention is to provide a kind of active pointer, this pointer can identify dynamics during user operation, and dynamics change is sent to touch-screen, ensures that the display of touch-screen truly can reflect the input of user, improves the precision of man-machine interaction.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of active pointer, comprise penholder, penholder front end is provided with nib, exciting bank is provided with in penholder, described nib is elastic conduction nib, also be provided with pressure sensitive unit and amplifier in described penholder, described pressure sensitive unit and elastic conduction nib fit tightly, and pressure sensitive unit, amplifier are connected successively with exciting bank; The pressure change of described pressure sensitive unit induction elastic conduction nib, and pressure change is converted into voltage signal; Described voltage signal is carried out amplification process by amplifier, and the voltage signal after amplifying is sent to exciting bank.
Further, described elastic conduction nib is PET elastic pen point.
The invention has the beneficial effects as follows, owing to have employed elastic conduction nib, when writing, there is deformation along with the pressure change of writing in elastic conduction nib, the change of pressure is converted into the change of voltage, finally passes to exciting bank, the pumping signal of respective intensities launched by exciting bank to touch-screen according to the change of voltage, make touch-screen perceive the change of writing physical strength, ensure that the display of touch-screen truly can reflect the input of user, improve the precision of man-machine interaction.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is structural representation of the present invention;
Fig. 2 is electrical principle block diagram of the present invention.
Embodiment
As shown in Figure 1, the invention provides a kind of active pointer, comprise penholder 1, penholder 1 front end is provided with elastic conduction nib 2, and elastic conduction nib 2 is preferably PET elastic pen point, is provided with pressure sensitive unit 3, amplifier 4 and exciting bank 5 in penholder 1; Pressure sensitive unit 3 and elastic conduction nib 2 fit tightly, and pressure sensitive unit 3, amplifier 4 are connected successively with exciting bank 5; Described pressure sensitive unit 3 responds to the pressure change of elastic conduction nib 2, and pressure change is converted into voltage signal; Described voltage signal is carried out amplification process by amplifier 4, and the voltage signal after amplifying is sent to exciting bank 5.
When writing, deformation is there is in elastic conduction nib 2 along with the pressure change of writing, the change of pressure is by pressure sensitive unit 3 perception, and convert the change of voltage to, the voltage signal of change is carried out amplification process by amplifier 4, and the voltage signal after amplifying is sent to exciting bank 5, thus changes the voltage in exciting bank 5, make change in voltage follower amplifier 4 output end voltage in exciting bank 5, that is the pressure of following elastic conduction nib 2 changes; When the pressure increase that elastic conduction nib 2 is subject to, voltage signal after conversion increases thereupon, simultaneously, voltage in exciting bank 5 also increases thereupon, the signal intensity being so finally transmitted to touch-screen increases thereupon, also namely export the pumping signal corresponding with elastic conduction nib 2 pressure to touch-screen, thus touch-screen can be made to demonstrate comparatively real written handwriting, improve the precision of man-machine interaction.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to the present invention; Any those of ordinary skill in the art, do not departing under technical solution of the present invention ambit, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solution of the present invention, or be revised as the Equivalent embodiments of equivalent variations.Therefore, every content not departing from technical solution of the present invention, according to technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent replacement, equivalence change and modification, all still belongs in the scope of technical solution of the present invention protection.
