Description

Technical Field

[0001] This application relates to the technical field of terminals, and in particular, to a terminal dust removal method, a terminal, and an electronic device. Background Art

[0002] A terminal (such as a mobile phone) is composed of numerous parts, including a dust-proof film (or dust-proof net). The dust-proof film can prevent small particles such as dust from entering the interior of the terminal through the sound outlet hole, thereby keeping the interior of the terminal clean, reducing the probability of terminal failures caused by small particles entering the interior of the terminal, and increasing the service life of the terminal.

[0003] When the dust-proof film is contaminated with dust, it will affect the sound of the speaker. Currently, automatic dust removal of the dust-proof film cannot be achieved. The common dust removal method is for users to manually remove dust using a brush or a sharp object (such as a toothpick, etc.). This method is likely to damage the dust-proof film, and further cause the terminal to lose its waterproof function. Summary of the Invention

[0008] Fourthly, an embodiment of the present application provides a computer-readable storage medium for storing computer-executable instructions, and when the computer-executable instructions are executed by a processor, the steps of the method described in the first aspect are implemented.

[0009] In the embodiment of the present application, by adding a piezoelectric material in the terminal, the inverse piezoelectric effect of the piezoelectric material can be utilized to clean the dust-proof film, avoiding damage to the dust-proof film caused by manual cleaning and improving the user experience. At the same time, this embodiment utilizes the direct piezoelectric effect of the piezoelectric material. Without adding new sensors, it is determined whether dust removal of the dust-proof film is required based on the change in voltage at both ends of the piezoelectric material, which can reduce the cost of the terminal, save the internal space of the terminal, and improve the user experience.

[0020] In order to enable those skilled in the art to better understand the technical solutions in the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0021] The terminal dust removal method provided in the embodiments of the present application mainly utilizes the direct piezoelectric effect and the inverse piezoelectric effect of piezoelectric materials. The following will first briefly introduce these two effects.

[0022] As Figure 1 shown, when a piezoelectric material is subjected to an external force, internal polarization occurs, and at the same time, charges with opposite signs are generated on two certain surfaces, and thus a voltage is formed between the above two surfaces; when the external force is removed, the material returns to the uncharged state; when the direction of the external force changes, the polarity of the charges also changes accordingly; the amount of charge generated by the material under the action of force is proportional to the magnitude of the external force, and this phenomenon is called the direct piezoelectric effect. In the embodiments of the present application, the direct piezoelectric effect of the piezoelectric material is used to determine whether dust removal of the dust-proof film is required.

[0023] In the case of applying an external force to the outside of the piezoelectric material, the charge Q generated by the piezoelectric material is the application of the direct piezoelectric effect, and specifically, the following formula can be referred to:

[0024] Q = C d *V = F * d 33

[0025] where d 33 and C d are piezoelectric constants, and in the case where the piezoelectric material is determined, the piezoelectric constants are values that can be obtained; the above F represents the magnitude of the external force.

[0026] Based on the above formula, the voltage V output by the piezoelectric material can be expressed by the relationship between the piezoelectric constant g 33 , thickness t, and cross-sectional area A of the piezoelectric material, and specifically, see the following formula:

[0027] V = F * d 33 / C d = F * g 33 *t / A

[0028] Figure 2 is the relationship between displacement and voltage of the piezoelectric material under the condition of being subjected to a constant force.

[0029] In addition, as Figure 1 shown, when a voltage signal is applied to the piezoelectric material, mechanical deformation occurs in some directions of the piezoelectric material, and the amount of deformation is proportional to the intensity of the voltage signal. This phenomenon is called the inverse piezoelectric effect. In the embodiments of the present application, the inverse piezoelectric effect of the piezoelectric material is used to drive the dust-proof film to move (such as high-frequency vibration), thereby achieving dust removal.

[0030] Figure 3 FIG. shows a schematic flow chart of a terminal dust removal method provided by an embodiment of the present application. This method can be executed by a terminal. In other words, the method can be executed by software or hardware installed in the terminal. As Figure 3 shown, the method may include the following steps.

[0031] S302: Detect the voltage across the piezoelectric material; wherein, the first end of the piezoelectric material is connected to the sound outlet hole component of the terminal, the second end of the piezoelectric material is connected to the dust-proof film of the terminal; the piezoelectric material is electrically connected to the voltage detection module of the terminal.

[0032] The piezoelectric material mentioned in various embodiments of the present application may be piezoelectric ceramics.

[0033] The dust-proof film mentioned in various embodiments of the present application may have the functions of air permeability and water resistance. Specifically, it may be an air-permeable and water-proof film. The following embodiments will mainly take the dust-proof film as an air-permeable and water-proof film as an example for description. The air-permeable and water-proof film is a filtering functional film that can block water and allow air to pass through. The air-permeable and water-proof film allows gas to pass through, while providing a reliable barrier to liquids such as water and oil, as well as fine dust and other pollutants.

[0034] The connection relationship between the piezoelectric material and the terminal will be described below.

[0035] As Figure 4 shown, the sound cavity design of the terminal mainly includes a sound outlet hole 1, an air-permeable and water-proof film 2, a front sound cavity 3, a speaker 5, a rear sound cavity 8, etc. The speaker 5 and the sound outlet hole component (the sound outlet hole component includes the sound outlet hole 1) can be connected through foam 6 and foam 9, and the side wall of the speaker 5 and the rear sound cavity 8 can be connected through foam 7.

[0036] Based on the above structure, a piezoelectric material is introduced in this embodiment. See Figure 4 the piezoelectric ceramic 4 in Figure 4In the shown direction, the upper end of the piezoelectric material is connected to the sound outlet hole component through a double-sided viscoelastic silicone sheet. The silicone sheet has damping adhesiveness and high elasticity. On the one hand, it can achieve the sealing of the front sound cavity; on the other hand, it can achieve the overall movement of the piezoelectric material and the breathable and water-blocking membrane. The piezoelectric material and the breathable and water-blocking membrane 2 can be bonded through a rigid polyurethane rubber material. Through bonding, the stable fixation of the piezoelectric material and the breathable and water-blocking membrane 2 is achieved, and the overall movement of the piezoelectric material and the breathable and water-blocking membrane 2 in the X-axis, Y-axis, and Z-axis directions is realized, so that the dust particles and sludge on the breathable and water-blocking membrane 2 are separated under the action of ultrasonic waves, achieving the effect of dust removal.

[0037] It should be noted that Figure 4 The voltage detection module of the terminal is not shown, nor is the electrical connection relationship between the voltage detection module and the piezoelectric material shown; nor is the voltage application module of the terminal shown, nor is the electrical connection relationship between the voltage application module and the piezoelectric material shown; among them, the voltage application module is mainly used to apply a voltage signal to the piezoelectric material.

[0038] When the breathable and water-blocking membrane 2 and the sound outlet hole 1 are blocked by dust or water droplets, the pressure in the front sound cavity 3 will change. Thus, as Figure 5 shown, the charge level generated by the piezoelectric material will change. Given the piezoelectric constant, thickness, and cross-sectional area of the piezoelectric material, the voltage across the piezoelectric material can be calculated. At this time, a correlation relationship between the voltage value and the amount of dust on the breathable and water-blocking membrane 2 can be established. When the voltage changes due to dust accumulation, the voltage will change slowly over a long period of time. When it reaches the critical value, it is determined that dust removal of the breathable and water-blocking membrane 2 is required.

[0039] S304: When it is determined that dust removal of the dust-proof membrane is required based on the change amount of the voltage, a voltage signal is applied to the piezoelectric material so that the piezoelectric material drives the dust-proof membrane to move for dust removal.

[0040] This step can determine whether dust removal of the dust-proof membrane is required based on the change amount of the voltage across the piezoelectric material; when it is determined that dust removal of the dust-proof membrane is not required, it can jump to execute S302, and S302 can be continuously executed at a certain time interval.

[0041] Optionally, this step of determining that dust removal of the dust-proof membrane is required based on the change amount of the voltage includes: determining that dust removal of the dust-proof membrane is required when at least one of the following conditions is met: the difference between the voltage detected this time and the voltage detected initially is greater than the first threshold; the difference between the voltages detected in two adjacent times is less than the second threshold.

[0042] Optionally, before this embodiment is executed, the method further includes: determining at least one of the first threshold and the second threshold based on the piezoelectric constant, thickness, and cross-sectional area of the piezoelectric material.

[0043] In this embodiment, the voltage detected for the first time may be the voltage detected for the first time after the last dust removal.

[0044] It can be understood that when there is dust on the sound outlet hole and the dust-proof film and the dust gradually accumulates, it will cause the voltage across the piezoelectric material to change slowly (gradually increase) over a long period of time. When the voltage reaches the critical value, that is, the difference between the voltage detected this time and the voltage detected for the first time is greater than the first threshold, it is determined that the dust-proof film needs to be dusted.

[0045] In addition, this embodiment considers that the difference between the voltages detected in two adjacent times is less than the second threshold, that is, the situation of voltage mutation is excluded, because voltage mutation is not caused by dust accumulation to a large extent, so that the timing of dust removal can be more accurate and the user experience can be improved.

[0046] Optionally, when it is determined that the dust-proof film needs to be dusted based on the change amount of the voltage in this embodiment, the state of the terminal can also be detected. When it is detected that the sound outlet hole of the terminal faces downward, the user can also be reminded to clean the sound outlet hole. Finally, in response to the confirmation information input by the user, a voltage signal is applied to the piezoelectric material, so that the piezoelectric material drives the dust-proof film to move for dust removal.

[0047] Optionally, when it is determined that the dust-proof film needs to be dusted based on the change amount of the voltage in this embodiment, the posture of the terminal can also be detected. When the posture of the terminal is suitable for dust removal (such as the terminal is placed flat), a voltage signal can be applied to the piezoelectric material, so that the piezoelectric material drives the dust-proof film to move for dust removal, realizing automatic dust removal without user participation.

[0048] The voltage signal applied to the piezoelectric material in this embodiment may be an ultrasonic signal, so that the piezoelectric material drives the dust-proof film to vibrate at a high frequency for dust removal.

[0049] Applying a voltage signal to both ends of the piezoelectric material in this embodiment can form an inverse piezoelectric effect, and the piezoelectric material will show a phenomenon of mechanical deformation. From this, ultrasonic vibration can be generated, thereby driving the dust-proof film to vibrate and removing the dust and sludge at the position of the dust-proof film and the sound outlet hole. Because the dust-proof film can block dust, the dust will not enter the terminal interior.

[0050] In this embodiment, the voltage signal required by the piezoelectric material is within the voltage range that the terminal main board can provide, and the energy consumption is not high, which is convenient for energy saving. At the same time, this embodiment makes full use of the existing voltage detection module in the terminal to detect the voltage across the piezoelectric material, and there is no need to add new sensors, which can save costs.

[0051] The terminal dust removal method provided by the embodiments of the present application can clean the dust-proof film by utilizing the inverse piezoelectric effect of the piezoelectric material through adding the piezoelectric material inside the terminal, avoiding the damage to the dust-proof film caused by manual cleaning and improving the user experience. At the same time, this embodiment utilizes the direct piezoelectric effect of the piezoelectric material. Without adding new sensors, it determines whether dust removal is required for the dust-proof film based on the change amount of the voltage at both ends of the piezoelectric material, which can reduce the cost of the terminal, save the internal space of the terminal, and improve the user experience.

[0052] The terminal dust removal method provided by the embodiments of the present application can be applied not only to terminals (such as tablets, cameras, earphones, etc.), but also to some devices equipped with dust-proof films.

[0053] Optionally, in Figure 3 In the embodiment shown, before applying a voltage signal to the piezoelectric material, the method further includes: determining the posture of the terminal; the step of applying a voltage signal to the piezoelectric material includes: when it is determined based on the posture of the terminal that it is suitable to perform dust removal on the dust-proof film (such as when the sound outlet of the terminal faces downwards), applying a voltage signal to the piezoelectric material.

[0054] This embodiment can further improve the dust removal effect and the user experience.

[0055] Before determining the posture of the terminal in this embodiment, the method further includes: detecting the current usage state of the terminal; the step of determining the posture of the terminal includes: when it is detected that the terminal is currently in use, determining the posture of the terminal.

[0056] This embodiment can enable user participation to determine whether dust removal is required by the user, improving the user experience.

[0057] Before applying a voltage signal to the piezoelectric material in this embodiment, the method further includes: the terminal sending a prompt message for indicating whether dust removal is required for the dust-proof film; the step of applying a voltage signal to the piezoelectric material includes: in response to the confirmation information input by the user, applying a voltage signal to the piezoelectric material.

[0058] Specific prompt messages can be interface prompts, vibration prompts, voice prompts, etc., which are not limited in this embodiment. An example of an interface prompt can be seen in Figure 6 .

[0059] In addition, the confirmation information input by the user is not limited to Figure 6 shown as the user clicking the "Clean Immediately" button on the interface, and can also be hardware button control, or even voice control, etc.

[0060] In this embodiment, before applying a voltage signal to the piezoelectric material, the method further includes: in response to denial information input by the user, jumping to the step of determining the posture of the terminal.

[0061] This embodiment can, in response to denial information input by the user, execute the step of determining the posture of the terminal after a certain time interval, which is convenient for energy saving and can improve the user experience.

[0062] In this implementation, the denial information input by the user is not limited to Figure 6 the user clicking the "Close" button on the interface shown.

[0063] In other embodiments, when it is detected that the terminal is currently in use, a prompt message can also be sent first, and the prompt message is used to indicate whether dust removal of the dust-proof film is required; in response to confirmation information input by the user, then detect the posture of the terminal. If the posture of the terminal is not suitable for dust removal (such as the sound outlet of the terminal is not facing down), the user is reminded to adjust the posture of the terminal to a suitable posture, and then a voltage signal is applied to the piezoelectric material to achieve dust removal; of course, when the posture of the terminal is suitable for dust removal (such as the sound outlet of the terminal is facing down), a voltage signal is applied to the piezoelectric material to achieve dust removal.

[0064] To illustrate in detail the terminal dust removal method provided by the embodiments of the present application, the following will be described in conjunction with specific embodiments one by one, as Figure 7 shown, this embodiment includes the following steps:

[0065] Judge whether the change amount of the voltage at both ends of the piezoelectric material is greater than a certain value.

[0066] In the case where the judgment result is yes, for example, when the difference between the voltage detected this time and the voltage detected initially is greater than the first threshold, it can be judged whether the voltage changes slowly.

[0067] In the case where the judgment result is no, for example, when the difference between the voltage detected this time and the voltage detected initially is less than the first threshold, the process can be ended.

[0068] In the case where it is judged that the voltage changes slowly, for example, when the difference between the voltages detected in two adjacent times is less than the second threshold, it can be detected whether the user is using the mobile phone.

[0069] In the case where it is judged that the voltage does not change slowly, for example, when the difference between the voltages detected in two adjacent times is greater than the second threshold, it can be postponed for one day, and then execute the step of judging whether the change amount of the voltage at both ends of the piezoelectric material is greater than a certain value.

[0070] When it is determined that the user is not using the mobile phone, it can be judged whether the posture of the mobile phone is suitable for dust removal. When the posture of the mobile phone is suitable for dust removal, a voltage can be output across the piezoelectric material to generate an ultrasonic sequence beneficial to dust removal, preferably for 20 s. When the posture of the mobile phone is not suitable for dust removal, it can be judged again whether the posture of the mobile phone is suitable for dust removal after a certain time interval.

[0071] When it is determined that the user is using the mobile phone, it can be judged whether the posture of the mobile phone is suitable for dust removal. When the posture of the mobile phone is suitable for dust removal, the user can be reminded whether to perform dust removal. When the posture of the mobile phone is not suitable for dust removal, it can be judged again whether the posture of the mobile phone is suitable for dust removal after a certain time interval.

[0072] After reminding the user whether to perform dust removal, in response to the confirmation information input by the user, a voltage can be output across the piezoelectric material to generate an ultrasonic sequence beneficial to dust removal, preferably for 20 s, and then the process ends. It can also, in response to the denial information input by the user, postpone for a period of time and then execute the step of judging whether the posture of the mobile phone is suitable for dust removal.
