Example two
Based on the foregoing embodiments, an embodiment of the present application provides a stylus, as shown in fig. 3, a hardware structure diagram of the stylus, where the stylus includes: a first output member 31 and a control switch 32;
and a control switch 32 electrically connected to the first output member 31 for controlling the first output member 31 to switch between a first circuit conduction state and a second circuit conduction state.
Specifically, the control switch 32 has two states, an open state and a closed state. In the present embodiment, switching of the first output section 31 between the first circuit on state and the second circuit on state is achieved by controlling opening and closing of the switch 32. For example, when the control switch is turned off, the first circuit is turned on and the second circuit is turned off, and when the control switch is turned off, the first circuit is turned off and the second circuit is turned on.
In embodiments provided herein, the stylus further includes a processor (not shown). The processor receives a control instruction of a user through a sensor or other sensing devices; further, the opening and closing of the control switch 32 is controlled based on a control instruction of the user.
In addition, a first output section 31 for outputting a first signal when the first circuit is on; the first signal is used for adjusting the capacitance value of a first touch panel adjacent to the touch pen; the first output component is used for adjusting the magnetic flux of the second touch panel adjacent to the touch pen when the second circuit is conducted.
In the embodiments provided herein, the first output member 31 is located within the stylus and at a predetermined distance from the stylus tip. Specifically, the first output member 31 may be an induction coil; the inductor of the first output section 31 is provided in the first circuit and the second circuit as a circuit element common to the first circuit and the second circuit.
Under the conducting state of the first circuit, the inductance coil outputs a first signal outwards; the first signal can change the capacitance value of the first touch panel, so that the first touch panel can determine the position of the current inductance coil corresponding to the first touch panel.
Further, in the on state of the second circuit, the inductance coil outputs a signal capable of cutting the magnetic induction coil of the second touch panel, and changes the magnetic flux of the second touch panel, so that the second touch panel can determine the specific touch position of the stylus pen according to the change of the magnetic flux.
In the embodiments provided herein, the stylus further includes a second output component 33;
here, the second output unit 33 is configured to output a second signal in the on state of the first circuit, so that the first touch panel obtains the tilt angle of the stylus pen relative to the first touch panel according to the received first signal and the received second signal; wherein the distance between the first output member and the second output member is greater than zero.
In the embodiments provided herein, the second output member 33 may be located at a tip of the stylus pen, and a distance between the first output member 31 and the second output member 33 in an extending direction of the stylus pen (the first output member and the second output member are equivalent to two points here) is a first length, where the first length is greater than zero.
Specifically, the second output section 33 outputs the second signal in the first circuit on state. Here, the second output section 33 is in an operating state in the first circuit on state, outputs the second signal, and does not output any signal when the second output section 33 is in the second circuit on state.
Further, the first output section 31 outputs the first signal in a first period in the first circuit on state, and the second output section 33 outputs the second signal in a second period in the first circuit on state. In this way, the first touch panel adjacent to the stylus can receive the first signal and the second signal, and the stylus calculates the tilt angle of the stylus by using the pythagorean theorem according to the coordinates of the first signal on the first touch panel, the coordinates of the second signal on the first touch panel, and the distance between the first output part 32 and the second output part 33.

The first output unit 31 is implemented by an inductor, and may adjust the magnetic flux of the second touch panel in the on state of the second circuit. Therefore, the functions of a capacitance pen and an electromagnetic pen are realized in one touch pen.
In the embodiment of the present application, the stylus pen further includes a receiving component 34, configured to receive an input signal from the second touch panel in a conducting state of the second circuit, obtain energy from the input signal, and convert the energy into a supply voltage;
and the first output component is connected with the receiving component and used for adjusting the magnetic flux of the second touch panel based on the power supply voltage in the conduction state of the second circuit.
Here, the first output means 31 may be the same structure as the receiving means 34. Specifically, when the second touch panel is an electromagnetic touch panel, and the second circuit in the stylus pen is turned on, the receiving unit 34 can receive an input signal of the second touch panel, accumulate electric energy based on the input signal, and convert the input signal into a supply voltage for the stylus pen to adjust the magnetic flux of the second touch panel based on the supply voltage. Thus, the function of the passive electromagnetic pen is realized. Therefore, when the power supply is not provided, the stylus can extract the electric energy from the second touch panel and realize the touch operation of the second touch panel.

The capacitance value of variable capacitor 55 can change according to the demand, and in the embodiment of the present application, the capacitance value of variable capacitor 55 can change according to the pressure information of gathering. In the embodiment provided by the present application, the variable capacitor 55 can be directly connected to the pressure sensor, and the capacitance value of the variable capacitor 55 can be directly changed according to the information transmitted by the pressure sensor.
Here, in the second circuit on state, a change in the capacitance value of the variable capacitance may directly affect a change in the frequency at which the first output section outputs the third signal.

In this way, the first touch panel adjacent to the stylus can receive the first signal and the second signal, and the stylus calculates the inclination angle of the stylus by using the Pythagorean theorem according to the first signal, the second signal and the distance between the first output component and the second output component. It should be noted that the first period and the second period are different.
It can be understood that the first output component is implemented by an inductance coil, and can output a first signal in a conducting state of the first circuit, and cooperate with a second signal output by the second output component, so that the first touch panel determines the tilt angle of the stylus pen. Moreover, the first output component is realized through the inductance coil, and the magnetic flux of the second touch panel can be adjusted under the conducting state of the second circuit.
The touch pen provided by the embodiment of the application comprises a first output component and a control switch; the control switch is electrically connected with the first output component and used for controlling the first output component to be switched between a first circuit conduction state and a second circuit conduction state; the first output component is used for outputting a first signal when the first circuit is conducted; the first signal is used for adjusting the capacitance value of a first touch panel adjacent to the touch pen; the first output component is used for adjusting the magnetic flux of a second touch panel adjacent to the stylus when the second circuit is conducted. Therefore, the touch control pen can realize the operation of the touch control panel with different working principles under the conduction states of different circuits; the dual-purpose function of one pen is realized, and the use efficiency of the touch control pen is improved.
