When the sound outlet is blocked, the sound outlet area is reduced, and the occurrence quality is affected, for example, referring to fig. 1b, a schematic diagram of the sound outlet blocking provided by the embodiment of the invention is shown, and when the circular sound outlet or the square sound outlet is blocked, as shown in fig. 1b, the sound outlet area is obviously reduced.
In order to reduce the blocking area of the sound outlet, a dust screen is usually arranged on the sound outlet so as to reduce the blocking condition of the blocking object to the sound outlet. The dust screen is typically a double layer dust screen, the construction of which is described below in connection with fig. 1 c.
Referring to fig. 1c, a schematic diagram of a dust screen according to an embodiment of the present invention is shown, where, as shown in fig. 1c, P01 is an appearance surface, and for a mobile terminal, here, glass or other planar materials (such as metal and the like); p02 is a metal decorative cover or a dustproof net with an outer layer containing metal material, and is used as a first protection and simultaneously ensures the integrity of an appearance surface; p03 is the sound hole of the decorative cover or the dust screen, the net structure, the air permeability is good, is used for making sound; p04 is an elastic material such as foam or silica gel for preventing sound leakage; p05 is a dust screen with an inner layer containing metal material, and the second protection is carried out; p06 is the sound hole of the inner layer dust screen, the net structure, the air permeability is good, is used for sound; p07 is a receiver or speaker, means for emitting sound; p08 is the electrical connection point of the decorative cover or the outer layer dust screen, and is grounded; p09 is the electrical connection point of the inner dust screen for providing charge to the capacitor and detecting.

When P08 is the first electrical connection point of the dust screen, P09 is the second electrical connection point of the dust screen; and when P08 is the second electrical connection point of the dust screen, P09 is the first electrical connection point of the dust screen.
P02 and P05 together form a planar capacitor, P08 and P09 as electrical connection points, which may be connected to a detection circuit, respectively, and may be used to detect the capacitance between the first and second mesh layers.
The detection circuit provided by the invention can be described as follows with reference to fig. 1 h.
Referring to fig. 1h, a schematic diagram of a detection circuit provided by an embodiment of the present invention is shown, and as shown in fig. 1h, a basic capacitance detection circuit prototype is shown (which is equivalent to the principle of a common capacitance microphone: c=q/U, where the capacitance change is converted into a voltage change, and then amplified by a transistor Q1 and output to a waveform detection device for detection).
The two electrical connection points (i.e., the first electrical connection point and the second electrical connection point) shown in fig. 1c are connected to the detection circuit, respectively, so that a voltage value between the two electrical connection points can be detected.
In the present invention, the detection circuit may be an ADC (analog-to-digital conversion) or a comparator, etc., and in particular, may be determined according to service requirements.
After energizing the first electrical connection point and the second electrical connection point, a voltage value between the first electrical connection point and the second electrical connection point may be obtained.
The normal voltage value refers to a voltage value between the first electrical connection point and the second electrical connection point detected when no jam occurs between the dust nets.
Under the condition that the dust screen is normal, the detection circuit may be started to obtain a normal voltage value between the first electrical connection point and the second electrical connection point, for example, referring to fig. 1d, a schematic diagram of a plate capacitor provided by the embodiment of the present invention is shown in fig. 1d, and under the condition that the dust screen is normal (i.e. the dust screen is not blocked), the capacitance values between the first network layer and the second network layer are: c=e S/d; wherein, C is the capacitance value, e is the dielectric constant between the first net layer and the second net layer, S is the effective area between the first net layer and the second net layer, and d is the plate spacing between the first net layer and the second net layer.
In the case that the dust-proof net is normal, after the detection circuit obtains the normal voltage value between the first electrical connection point and the second electrical connection point, step 202 is performed.
Step 202: and obtaining a second output power of the detection circuit.
Output power (nominal power) is also called: the nominal output power refers to the maximum value of the output power which can work for a long time under the premise of no distortion of the electric appliance, and the maximum power refers to the maximum value of the instantaneous power under the premise of no damage to the electric appliance, namely the maximum load capacity which can be born by the electric appliance. Output power = input power-power of idle work.
The second output power refers to the effective power provided by the detection circuit for the first network layer and the second network layer under the condition that the dust screen is normal.
It will be appreciated that the second output power may be determined when the detection circuit is in operation, and the manner in which the second output power is determined is well known in the art, and the embodiment of the present invention is not limited in how to obtain the first output power.
After the second output power of the detection circuit is acquired, step 203 is performed.
Step 203: and determining a normal capacitance value between the first network layer and the second network layer according to the normal voltage value and the second output power.
After obtaining the normal voltage value between the first electrical connection point and the second electrical connection point and detecting the second output power of the circuit, the normal capacitance value between the first network layer and the second network layer may be determined according to the normal voltage value and the second output power, specifically, the formula may be combined: and C=Q/U, calculating a normal capacitance value, wherein C is the normal capacitance value, Q is the normal voltage value, and U is the second output power.
After determining the normal capacitance value between the first and second net layers based on the normal voltage value and the second output power, step 204 is performed.
Step 204: and determining a capacitance threshold interval according to the normal capacitance value.
The reasons for the change in capacitance between the first and second mesh layers are mainly divided into the following:
1. the effective area of the flat plate changes
When the effective area between the first net layer and the second net layer changes, according to a capacitance formula: when c=e is increased, and e and d are unchanged, the capacitance C is increased, for example, referring to fig. 1e, a schematic diagram of a change in the effective area of a flat plate according to an embodiment of the present invention is shown, as shown in fig. 1e, after holes on a dust screen or a decorative cover are blocked, because the blocking object is composed of liquid and impurities, and has a certain conductivity, together with the metal dust screen, the effective area of the flat plate capacitance is increased, that is, the effective area between the first mesh layer and the second mesh layer is increased, thereby increasing the capacitance between the two mesh layers.
2. The distance between the plates is changed
When the distance between the first net layer and the second net layer is changed, according to a capacitance formula: c=e×s/d, d increases or decreases, and in the case where e and S are unchanged, the capacitance C increases or decreases, for example, referring to fig. 1f, a schematic diagram of a plate spacing change provided in an embodiment of the present invention is shown, as shown in fig. 1f, after a hole of a dust screen is plugged, the dust screen is pushed by the airflow to deform when a receiver or a speaker is in a sound producing state, so that the plate spacing d between two plates of a parallel plate capacitor changes (may increase or decrease), and the capacitance between two mesh layers changes.
3. Medium between plates is changed
When the dielectric constant between the first net layer and the second net layer changes, according to the capacitance formula: c=e×s/d, e increases or decreases, and S and d are unchanged, which may result in an increase or decrease in capacitance C, for example, referring to fig. 1g, a schematic diagram of a medium change between plates is shown in an embodiment of the present invention, where as shown in fig. 1g, when there are more plugs between the first mesh layer and the second mesh layer, the plugs are accumulated between the two dust meshes, which may result in a medium change between plates to change the medium constant e (which may increase or decrease).
As can be seen from the above capacitance formula, the capacitance between the first mesh layer and the second mesh layer changes when the above situations occur.
After obtaining the normal capacitance value between the first network layer and the second network layer, a service personnel may undergo multiple tests according to the normal capacitance value to give a set capacitance threshold interval (i.e. including a minimum capacitance threshold value and a maximum capacitance threshold value), and the process of obtaining the capacitance threshold interval may be determined according to the service requirement, which is not limited by the embodiment of the present invention.
After determining the capacitance threshold interval from the normal capacitance value, step 205 is performed.
Step 205: and acquiring a voltage value between the first electrical connection point and the second electrical connection point through a detection circuit.
After the first electrical connection point and the second electrical connection point are electrified, a voltage value between the first electrical connection point and the second electrical connection point can be obtained, and in a specific implementation, the operation of obtaining the voltage value can be executed every preset time under the condition that a screen of the mobile terminal is in a bright screen state.
The preset time may be preset by a service person, may be 10 min, 30min, etc., and specifically may be determined according to actual situations.
According to the invention, the preset time is set, and the voltage detection is executed every preset time when the screen is on, so that the power consumption of the mobile terminal in standby can be saved.
After the voltage value between the first electrical connection point and the second electrical connection point is obtained by the detection circuit, step 206 is performed.
Step 206: and determining a capacitance value between the first network layer and the second network layer according to the voltage value and the first output power of the detection circuit.
The first output power refers to the effective power provided by the detection circuit for the first network layer and the second network layer.
It will be appreciated that the first output power may be determined when the detection circuit is in operation, and the manner of the first output power is already a mature technology in the art, and the embodiment of the present invention is not limited to how to obtain the first output power.
After obtaining the voltage value between the first electrical connection point and the second electrical connection point and detecting the first output power of the circuit, the capacitance value between the first network layer and the second network layer may be determined according to the voltage value and the first output power, and specifically, the formula may be combined: c=q/U, where C is the capacitance, Q is the voltage, and U is the first output power.
After determining the capacitance value between the first network layer and the second network layer based on the voltage value and the first output power of the detection circuit, step 207 is performed.
Step 207: and under the condition that the capacitance value is outside a capacitance threshold interval, determining that the dust screen is blocked.

The specific range of the capacitor threshold interval can be determined according to the service requirement, and the embodiment of the invention is not limited to this.
The capacitance threshold interval may be an interval range formed by the minimum threshold value and the maximum threshold value, and when the acquired capacitance value is in the interval of the minimum threshold value and the maximum threshold value, that is, when the capacitance value is in the capacitance threshold interval, the blocking condition between the first network layer and the second network layer is lighter, that is, the blocking of the dust screen is not abnormal yet.
And when the capacitance value is smaller than the minimum threshold value or larger than the maximum threshold value, namely, the capacitance value is outside the capacitance threshold interval, the dust screen is determined to be abnormal, namely, the blocking condition between the first net layer and the second net layer is serious.

After determining that the dust screen is abnormal, step 208 is performed.
Step 208: outputting prompt information for prompting a user to clean the dust screen under the condition that the capacitance value is larger than a first capacitance threshold value or smaller than a second capacitance threshold value.
In the invention, a first capacitance threshold value and a second capacitance threshold value can be preset, wherein the first capacitance threshold value is larger than the maximum value corresponding to the capacitance threshold interval, and the second capacitance threshold value is smaller than the minimum value corresponding to the capacitance threshold interval.
The first capacitor threshold value and the second capacitor threshold value are threshold values which are preset by service personnel and used for sending prompt information to a user and prompting the user to clean the dust screen in time.
Under the condition that the capacitance value is larger than the first capacitance threshold value or smaller than the second capacitance threshold value, prompt information for prompting a user to clean the dust screen can be output, specifically, the user can be notified in an interface or voice mode, cleaning operation of the dust screen is required, and the influence caused by dirt of the screen cloth is prompted.
