Description
Technical field
This utility model relates to a kind of active pointer.
Background technology
Along with the development of science and technology, touch technology is widely used to the multimedia equipments such as notebook computer, panel computer, mobile phone.When finger touches capacitance plate, owing to human body electric field, finger and work surface form a coupling electric capacity, then finger walks a electric current the least, this is equivalent to the change of electrode capacitance at touch point, and the touch chip of touch screen may determine that the position of touch point by the change of detecting electrode electric capacity.In addition to can carrying out touch control operation touch screen by finger, it is also possible to use felt pen to carry out operating of contacts.
Pointer is generally divided into passive type pointer and active pointer.The operating principle of passive type pointer is similar to finger, is that the finger using the nib and user with conductive characteristic is connected, is equivalent to the aid for extending finger.Active pointer then can launch pumping signal by internal exciting bank, in order to change the electric field at touch point, thus changes the electrode capacitance at touch point, and touch chip i.e. can determine that 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 cause the input of user to there is bigger deviation with the display output of touch screen, the ratio of precision of man-machine interaction is relatively low.
Utility model content
The purpose of this utility model is to provide a kind of active pointer, and this pointer is capable of identify that dynamics during user operation, and dynamics change is sent to touch screen, it is ensured that the display of touch screen can truly reflect the input of user, improves the precision of man-machine interaction.
This utility model solves its technical problem and be the technical scheme is that
A kind of active pointer, including penholder, penholder front end is provided with nib, exciting bank it is provided with in penholder, described nib is elastic conduction nib, being additionally provided with pressure sensitive unit and amplifier in described penholder, described pressure sensitive unit fits tightly with elastic conduction nib, and pressure sensitive unit, amplifier are sequentially connected in series with exciting bank；The pressure change of described pressure sensitive unit sensing elastic conduction nib, and pressure change is converted into voltage signal；Amplifier described voltage signal is amplified process, and will amplify after voltage signal be sent to exciting bank.
Further, described elastic conduction nib is PET elastic pen point.
The beneficial effects of the utility model are, owing to have employed elastic conduction nib, when writing, elastic conduction nib deforms upon along with the pressure change write, and the change of pressure is converted into the change of voltage, is ultimately transferred to exciting bank, the pumping signal of respective intensities launched by exciting bank according to the change of voltage to touch screen, make touch screen perceive the change of writing physical strength, it is ensured that the display of touch screen can truly reflect the input of user, improve the precision of man-machine interaction.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is electrical principle block diagram of the present utility model.
Detailed description of the invention
As it is shown in figure 1, this utility model provides a kind of active pointer, including 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 fits tightly with elastic conduction nib 2, and pressure sensitive unit 3, amplifier 4 are sequentially connected in series with exciting bank 5；Described pressure sensitive unit 3 senses the pressure change of elastic conduction nib 2, and pressure change is converted into voltage signal；Amplifier 4 described voltage signal is amplified process, and will amplify after voltage signal be sent to exciting bank 5.
When writing, elastic conduction nib 2 deforms upon along with the pressure change write, the change of pressure is by pressure sensitive unit 3 perception, and it is converted into the change of voltage, the voltage signal of change is amplified processing 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 follow-up amplifier 4 output end voltage in exciting bank 5, that is the pressure following elastic conduction nib 2 is changed；When elastic conduction nib 2 pressure experienced increases, voltage signal after conversion increases therewith, simultaneously, voltage in exciting bank 5 increases the most therewith, the signal intensity being the most finally transmitted to touch screen increases therewith, namely output with the elastic conduction nib corresponding pumping signal of 2 pressure to touch screen, such that it is able to make touch screen demonstrate more real written handwriting, the precision of raising man-machine interaction.
The above, be only preferred embodiment of the present utility model, and this utility model is not made any pro forma restriction；Any those of ordinary skill in the art, without departing under technical solutions of the utility model ambit, technical solutions of the utility model are made many possible variations and modification by the method and the technology contents that all may utilize the disclosure above, or are revised as the Equivalent embodiments of equivalent variations.Therefore, every content without departing from technical solutions of the utility model, to any simple modification made for any of the above embodiments, equivalent, equivalence change and modify according to technical spirit of the present utility model, all still fall within the range of technical solutions of the utility model protection.
