Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1, a flowchart of embodiment 1 of a processing method provided by the present application is applied to an electronic device, and the method includes the following steps:
step S101: acquiring a first instruction;
the first instruction is an instruction for controlling the screen to generate a first sound wave signal.
Step S102: responding to the first instruction, and controlling a screen to generate a first sound wave signal; wherein the first friction force can be formed by the touch of the operating body on the screen generating the first sound wave signal.
Wherein the first friction is smaller than a second friction, and the second friction is formed by touching the operation body on a screen on which the first acoustic wave signal is not generated.
Wherein, the operation body can generate friction force when touching the screen.
In specific implementation, the first sound wave signal can be an ultrasonic wave signal, the ultrasonic wave is a sound wave with the frequency higher than 2 kilohertz, the directivity is good, the penetrating power is strong, more concentrated sound energy is easy to obtain, and the friction force of the screen can be reduced by the ultrasonic vibration on the screen.
Moreover, the vibration frequency of the ultrasonic wave is far higher than the hearing range of human ears, and the sound heard by the human ears is not influenced.
In the present embodiment, the friction force of the friction surface on the electronic device is reduced based on the ultrasonic vibration.
In the specific implementation, the vibration force generated by the first sound wave signal is enough to overcome the gravity of the operation body, and the effect is represented as that the suspended touch sensation is generated when the operation body touches the touch screen.
Specifically, the formation and separation of contact between the operating body and the screen during the ultrasonic vibration of the screen can create a minute gap, and a medium lubricating film (e.g., air film) can be actively formed in this gap to improve the lubricating environment of the contact, resulting in a reduction in the coefficient of friction, thereby reducing the frictional force.
Since a high-pressure air film is formed between the finger and the surface of the touch panel, the resistance between the finger and the touch panel is reduced by the floating effect of the air film, and the finger feels smooth. In addition, if the floating and non-floating states alternately appear, the user may feel an illusive sense of astringency.
In summary, the processing method provided in this embodiment includes: acquiring a first instruction; responding to the first instruction, and controlling a screen to generate a first sound wave signal; the touch of the operation body on the screen generating the first sound wave signal can form a first friction force, the first friction force is smaller than a second friction force, and the second friction force is formed by the touch of the operation body on the screen not generating the first sound wave signal. In the scheme, the screen can be controlled to generate the first sound wave signal based on the instruction, so that a smaller friction force is generated when the operation body touches the screen compared with the situation that the first sound wave signal is not generated, and compared with the prior art that the screen generation technology can only be used for generating sound which can be heard by human ears, the scheme also controls the screen to generate touch sense except the sound which can be heard by the human ears, and the application range can be improved.
As shown in fig. 2, a flowchart of embodiment 2 of a processing method provided by the present application includes the following steps:
step S201: acquiring a first instruction;
step S202: responding to the first instruction, and controlling a screen to generate a first sound wave signal; wherein, the touch of the operating body on the screen generating the first sound wave signal can form a first friction force;

S204: and responding to the second instruction, controlling the screen to generate a second sound wave signal.
The frequency of the first sound wave signal is greater than a preset frequency, and the frequency of the second sound wave signal is less than or equal to the preset frequency; when the screen only generates the second acoustic wave signal, the second friction force can be formed by the fact that the operating body touches the screen.
Since the auditory range of the human ear is between 20Hz to 20000Hz, sounds outside this range are inaudible to the human ear; sounds above 20000Hz are called ultrasound.
The preset frequency may be 2 khz specifically, and when the frequency of the sound wave signal is greater than 2 khz, the sound wave signal is an ultrasonic wave, and the sound wave is audible to human ears and is less than 2 khz.
Therefore, when the screen is controlled to generate only the second sound wave signal in response to the second instruction, the operating body touches the screen to form a second friction force.
The second friction force is formed when the operating body is normally contacted with the screen, and the first friction force is based on ultrasonic vibration, so that the resistance between the operating body and the touch screen is reduced, namely the first friction force is smaller than the second friction force.
In summary, the processing method provided in this embodiment further includes: acquiring a second instruction; responding to the second instruction, controlling a screen to generate a second sound wave signal; the frequency of the first sound wave signal is greater than a preset frequency, and the frequency of the second sound wave signal is less than or equal to the preset frequency; when the screen only generates the second acoustic wave signal, the second friction force can be formed by the fact that the operating body touches the screen. In the scheme, the screen can be controlled to generate the first sound wave signal based on the instruction, so that the operating body generates smaller friction force when touching the screen relative to the situation that the first sound wave signal is not generated, sound which can be heard by human ears can be emitted, and the application universality can be improved.

Specifically, the exciter generates a vibration frequency of more than 2 kilohertz, and drives the screen to vibrate to generate a first sound wave signal.

Specifically, the exciter generates vibration based on the control of the first instruction to drive the screen fixedly connected with the exciter to vibrate, the vibration frequency of the exciter is more than 2 kilohertz, the screen generates an ultrasonic signal, the ultrasonic signal exceeds the hearing frequency range of human ears, a user cannot hear the sound wave, but when an operation body (such as a finger) touches the screen, the operation body can feel that the friction force of the screen is reduced or even cannot feel the friction force based on the touch sense, and a floating effect is generated.
Step S303: acquiring a second instruction;
step S303 is the same as step S203 in embodiment 2, and details are not described in this embodiment.
S304: and controlling an exciter to generate vibration based on a second instruction, so that the exciter drives the screen to vibrate to generate the second sound wave signal.
In this embodiment, in response to the second instruction, specifically, the actuator is controlled to generate vibration based on the second instruction, the actuator is fixedly connected to the screen, the actuator vibrates to drive the screen to vibrate, and the screen vibrates to generate the second sound wave signal.
Specifically, the exciter can also generate a vibration frequency below 2 kilohertz, so as to drive the screen to vibrate to generate a second sound wave signal.
In a specific implementation, the exciter can respectively vibrate based on the control of the first instruction and the second instruction so as to drive the screen to vibrate to respectively generate a first sound wave signal and a second sound wave signal; the exciter can also simultaneously generate vibration based on the control of the first instruction and the second instruction so as to drive the screen to vibrate and simultaneously generate the first sound wave signal and the second sound wave signal.
In a specific implementation, the processing module for controlling the exciter may superimpose the first instruction and the second instruction and send the superimposed signals to the exciter, so that the exciter drives the screen to vibrate and generate audio and ultrasonic waves at the same time based on the superimposed signals.

Step S502: responding to the first instruction, and controlling the screen to generate a first sound wave signal through a switch signal; wherein the switching signal is used for controlling the magnitude of the first friction force.
The switching signal specifically adopts a PWM (Pulse Width Modulation) signal.
Specifically, the first acoustic wave signal is generated by high level control of the PWM signal, and the first acoustic wave signal is not generated by low level control.
Specifically, the frequency or duty ratio of the PWM signal is controlled so that the screen intermittently generates the first sound wave signal.
When the frequency of the PWM signal is high, the duty ratio of the PWM signal is adjusted to change the proportion of the time for generating the first sound wave signal in the period to the time for not generating the first sound wave signal, and then the proportion of the time for generating the first friction force formed by the operating body on the touch screen in the period is changed, so that the first friction force in the period is changed.
Generally, the larger the PWM duty ratio, the smaller the first frictional force generated by the operator touch.
It should be noted that, the magnitude of the first friction force is controlled based on the switching signal, and the frequency of the PWM signal is high (e.g. 1000 hz), so that the operating body does not sense the discontinuity of the first sound wave signal.

Step S602: responding to the first instruction, controlling a screen to generate a first sound wave signal, wherein the amplitude of the first sound wave signal is used for controlling the first friction force.
Wherein the amplitude of the first acoustic signal is related to the magnitude of the first friction.
Specifically, the larger the amplitude of the first acoustic wave signal is, the smaller the first frictional force formed by the operating body touching the screen is, and conversely, the smaller the amplitude of the first acoustic wave signal is, the larger the first frictional force formed by the operating body touching the screen is.
In a specific implementation, the touch of the operation body on the screen may be a sliding touch or a clicking touch.
Specifically, the sensed friction force may be changed during the sliding touch of the operation body on the screen.

Step S702: determining the current display state of a display area corresponding to the current touch position on the screen;
specifically, when the current touch position of the operation body on the screen is determined, the current display state of the display area corresponding to the touch position is further determined.
Wherein the display state includes: no display content, and specific content.
Specifically, the non-display content may be a black screen, a white screen, or the like.

Specifically, the content of the display area may be fixed at the current position, and may be movable in accordance with the touch operation of the operation body.
Fig. 8 is a schematic diagram of a screen, in which an apple pattern is displayed, the apple pattern is a first area 801, the other areas are 802, a finger of a user slides on the screen, and friction generated by touch in the first area is different from that generated by touch in the other areas. Specifically, if the friction force of the finger in the other area is smaller than the friction force in the first area, the first instruction is generated to reduce the friction force when the current touch position of the finger on the screen is determined, and the screen display state corresponding to the current touch position is determined to be that the apple pattern is not displayed, and the first instruction is not generated when the screen display state corresponding to the current touch position is determined to be that the apple pattern is displayed.

Specifically, the more objects dragged, the greater the friction, and the interactive experience is associated with the actual experience.
Specifically, the fewer the dragged objects are, the smaller the friction force is, so that the interaction is easier.
The relation between the dragging object amount and the friction force can be set according to the actual situation, and the application is not limited.
