When the electronic device receives the user's selection input, the first identification may be determined based on the pen tip type and/or paper type selected by the user, and the first identification may be sent to the stylus.

In an implementation form, the obtaining the first identifier includes:

In the case of receiving the first input of the user, the first identifier is determined according to the input parameter of the first input.

Step 502: Determine a first vibration curve matching the first identifier in a preset vibration curve set.

In this embodiment of the present application, the stylus may be preset with a vibration curve set, which is referred to as the preset vibration curve set here, and the vibration curve in the preset vibration curve set is determined by the type of the pen tip and/or the type of paper. to identify.

Among them, in the case of a linear relationship between the current intensity of the driving current and the vibration amplitude of the linear motor, the relationship between the current intensity of the driving current and the vibration amplitude of the linear motor can be expressed as:

A(t)=k·I(t)+b,

but,

In the case of a nonlinear relationship between the current intensity of the driving current and the vibration amplitude of the linear motor, the relationship between the current intensity of the driving current and the vibration amplitude of the linear motor can be expressed as:

A(t)=f(I(t))+b,

Then, I(t)=f ^-1 (A(t)-b),

When the tip of the stylus is slid on the screen of the electronic device, the control unit can control the linear vibration. The motor vibrates based on the vibration curve in different writing scenarios to simulate the vibration of real writing, so that the user can feel the tactile feeling close to real writing.

In the embodiment of the present application, optionally, the first vibration curve is a vibration curve that matches the first identifier in the first case, and the first case is that the tip of the stylus is on the screen with a predetermined pattern.

In this embodiment, since the vibration frequency during writing is related to the writing speed, the preset vibration curve set preset by the stylus may be the vibration curve corresponding to when the pen tip moves at a predetermined speed at a constant speed. When it is detected that the pen tip is in contact with the screen of the electronic device and moves on the screen of the electronic device, the vibration frequency of the vibration curve can be adjusted correspondingly according to the real-time speed of the pen tip movement, and the vibration sense of the linear motor can follow the change of the writing speed. , to further improve the proximity between the vibration sense simulated by the linear motor and the vibration sense of real writing, and further improve the user experience.

In specific implementation, the preset speed of the stylus may be 1 cm/s, and when the tip of the stylus moves on the screen of the electronic device, the The pen head slides to calculate the real-time speed, and the real-time speed v can be expressed as:

Wherein, dx and dy are the distances that the tip of the stylus moves on the X axis and the Y axis of the screen of the electronic device in unit time, and the unit of v is cm/s.

The stylus can preset that the real-time speed is positively correlated with the vibration frequency, so the adjusted real-time frequency can be determined according to the ratio of the real-time speed to the preset speed and the current first frequency of the vibration curve. , under the condition that the variation law of the vibration amplitude of the first vibration curve is kept unchanged, the vibration frequency of the first vibration curve is adjusted to obtain the second vibration curve.

It should be noted that, in other embodiments, the real-time speed of writing and the vibration frequency may also be a linear relationship, or other functional relationship, which may be determined according to the actual situation, which is not limited in the embodiments of the present application.

In the embodiment of the present application, optionally, after obtaining the first identifier, the method further includes:

In this way, the writing effect of the stylus pen can be closer to the writing effect of real writing by combining the multiple tactile sensations of vision, hearing and touch.

In a specific implementation, the stylus may be preset with an audio set, which is referred to as the preset audio set here, and the audio in the preset audio set is identified by the pen tip type and/or the paper type. Specifically, the stylus can pre-record writing sounds in different writing scenarios.

When it is detected that the pen tip is in contact with the screen of the electronic device and moves on the screen of the electronic device, the real-time pitch of the audio can be adjusted correspondingly according to the real-time speed of the pen tip movement, and the pitch of the played audio can follow the change of the writing speed. Further improve the proximity between the auditory effect of playing audio simulation and the auditory effect of real writing, and further improve the user experience.

The stylus can preset that the real-time speed is positively correlated with the real-time pitch, so the adjusted real-time pitch can be determined according to the ratio of the real-time speed to the preset speed and the current first pitch of the audio, The second audio is obtained.
