The technical solutions in the embodiments of the present application will be clearly described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art fall within the scope of protection of this application.

It is to be understood that the figures so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in orders other than those illustrated or described herein, and that "first," "second," etc. are distinguished Objects are usually of one type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the related objects are in an "or" relationship.

For terminal equipment including microphones, impurities entering the interior of the microphone tend to adhere near the diaphragm of the microphone. Therefore, during the use of the microphone, the sticky state of impurities will affect the normal vibration of the microphone's diaphragm, thereby generating noise.

To this end, embodiments of the present application provide a microphone control method, device, electronic device, and readable storage medium. Specifically, after applying the operating voltage to the microphone, starting the microphone, and before using the microphone to obtain audio data, the target voltage is applied to the audio receiving unit in the microphone. Pressure can make the vibration amplitude of the diaphragm in the audio receiving unit reach the target vibration amplitude. In the process of the diaphragm generating the target vibration amplitude, the impurities can be adjusted to enter the fracture state. When the impurities are in a fractured state, the impact of the impurities on the normal vibration of the diaphragm can be effectively reduced and the generation of noise can be avoided.

The microphone control method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios.

FIG. 1 is a schematic flowchart of a microphone control method provided by an embodiment of the present application. As shown in FIG. 1 , a microphone control method may be applied to an electronic device including a microphone, and the method may include steps 110 to 120 .

Step 110: Detect whether the screen of the electronic device is lit.

Specifically, the electronic device may be a device including a microphone, and the electronic device may be, for example, a mobile phone, a tablet computer, a notebook computer, a palmtop computer, and other devices. During the operation of the microphone, the microphone can convert the sound signal into an electrical signal. Examples of microphone types include, but are not limited to, dynamic, condenser, electret, and silicon micromicrophones. Specifically, after the microphone is started, the electrical signal corresponding to the sound signal can be obtained through the vibration of the diaphragm.

In some embodiments, during the manufacturing process of the electronic device, impurities such as flux are inevitably introduced into the interior of the electronic device. For electronic equipment including microphones, impurities entering the microphone tend to stick near the diaphragm of the microphone. For example, flux volatilizes into the microphone at high temperatures and easily accumulates near the diaphragm, thus affecting the normal vibration of the diaphragm.

In order to reduce the impact of impurities on the normal vibration of the diaphragm, you can determine whether the electronic device has the possibility of using a microphone by detecting the display status of the screen. For example, when the screen of the electronic device is in the display state, the user may be using the electronic device, and an application in the electronic device that can call the microphone may also be opened. Examples of applications that call the microphone, such as voice assistant applications, phone calls, social networking applications, etc., are not listed here. When the application is running, the microphone can be called and audio data obtained through the microphone.

Step 120: Apply a target voltage to the microphone when it is detected that the screen of the electronic device is lit.

Specifically, when it is detected that the screen of the electronic device is lit, a target voltage can be immediately applied to the microphone to cause the diaphragm in the microphone to vibrate in response to the target voltage.

As a specific example, taking a silicon micromicrophone as an example, the diaphragm and the back plate form the two poles of the parallel plate capacitor. When the diaphragm receives the sound wave vibration, the distance between the diaphragm and the back plate changes, resulting in parallel The capacitance of the plate capacitor changes, and the acoustic signal can be converted into an electrical signal by collecting voltage fluctuations. Based on this, by applying a certain voltage to the diaphragm, the diaphragm can be controlled to vibrate.

Because in the process of the diaphragm generating the target vibration amplitude, the stickiness state of impurities to the diaphragm can be changed. In the embodiment of the present application, when it is detected that the screen of the electronic device is lit, the target voltage is immediately applied to the microphone, which enables the diaphragm to vibrate in advance before the microphone is called by the application, thereby allowing the microphone to be used later. In the process, the impact of impurities on the normal vibration of the diaphragm is effectively reduced and noise is avoided.

As a specific example, the microphone includes a diaphragm support column, a base and a back plate. The base is connected to the diaphragm through the diaphragm support column. The back plate and the diaphragm form the two poles of the capacitor; applying a target voltage to the microphone, specifically It includes: applying a target voltage to the diaphragm and the back plate, causing the diaphragm to vibrate in response to the target voltage, and separating the diaphragm support column of the microphone from the base.

For example, the diaphragm can be the positive electrode of the capacitor, and the back plate can be the negative electrode of the capacitor. By applying a target voltage to the diaphragm and the back plate, the diaphragm can be pulled up through charge attraction, thereby controlling the diaphragm support column. The separation from the base enables adjustment of the adhesion state of impurities.

FIG. 2 is a schematic structural diagram of a microphone provided by an embodiment of the present application. As shown in FIG. 2 , the microphone includes a diaphragm 201 , a back plate 202 , and a base 203 . The base 203 is connected to the diaphragm 201 through the diaphragm supporting pillars, that is, the diaphragm is arranged on the base through the diaphragm supporting pillars. The diaphragm 201 and the back plate 202 form a capacitor. Figure 3 is a schematic structural diagram of another microphone provided by an embodiment of the present application. As shown in FIG. 3 , a diaphragm supporting column 301 and a diaphragm supporting column 302 are included between the base and the diaphragm. In the natural resting state, the relationship between the diaphragm support pillars between the diaphragm 201 and the base 203 is as shown in Figure 3(a). In the vibrating state, if there are no impurities sticking to the position where the diaphragm support column and the base are in contact with each other, the diaphragm 201 moves upward to lift the diaphragm support column, and the diaphragm support column is between the diaphragm 201 and the base 203 The relationship is shown in Figure 3(b).

For terminal equipment including a microphone, after impurities enter the interior of the microphone, the impurities may stick to the position where the diaphragm support column and the base contact each other. Illustratively, Figure 4 is an example provided by the embodiment of the present application. Schematic diagram of impurities sticking. As shown in Figure 4(a), the sticky state of impurities 401. During the operation of the microphone, the diaphragm vibrates in response to sound signals. For example, the flux has strong viscosity impurities. During the vibration process of the diaphragm, the impurities are in a sticky state 402, as shown in Figure 4(b). At this time, the impurities are not completely separated. That is, the viscosity of the impurities will inhibit the upward movement of the diaphragm. However, as the diaphragm continues to vibrate, as the diaphragm stretches, the sticky impurities will eventually break off. At this time, the instantaneous inertia will cause the diaphragm to move upward. Extreme time produces a rapid displacement, and the impurities enter the fracture state 403, as shown in Figure 4(c).

Since the diaphragm and the back plate form a capacitor, the expression formula (1) of the capacitance C of the parallel plate capacitor is combined.

Among them, S represents the area of the parallel plates, d is the distance between the two plates, k represents the electrostatic force constant, and ε is the relative dielectric constant. Therefore, for the capacitor formed by the diaphragm and the back plate, since the area S of the capacitor formed by the diaphragm and the back plate is fixed, the capacitance value is related to the distance d between the diaphragm and the back plate.

Therefore, when the instantaneous inertia causes the diaphragm to produce a rapid displacement d at an extreme time, it will cause the capacitance value to decrease instantaneously, combined with U=Q/C, where U is the voltage and Q is the charge. When the capacitance value drops instantaneously, it will cause the voltage to jump, which will cause noise during use of the microphone. If the diaphragm returns to its natural resting state within a period of time, the sticky impurities will be re-adsorbed, causing noise to still be generated the next time the microphone is used.

In the embodiment of the present application, when it is detected that the screen of the electronic device is lit, the target voltage is immediately applied to the microphone, so that the diaphragm can vibrate in advance and drive the diaphragm support before each microphone is called by the application program. Separation of column from base. That is, the impurities between the diaphragm support pillar and the base are advanced to the fracture state 403 as shown in Figure 4(c). Based on this, during the subsequent use of the microphone, since the impurities have entered the fracture state 403, during the subsequent operation of the microphone, the impact of the impurities on the normal vibration of the diaphragm is effectively reduced, and the generation of noise can be avoided.

FIG. 5 is a schematic structural diagram of a microphone control circuit provided by an embodiment of the present application. As shown in FIG. 5 , the microphone control circuit may include a micro-electro-mechanical system (MEMS) acoustic part and an application specific integrated circuit (Application Specific Integrated Circuit, ASIC) part. The voltage can be provided to the microphone through VDD1, and next, through the charge pump (charge pump) The control circuit may apply a target voltage to the audio control unit.

Optionally, the electronic device may be provided with a separate microphone control chip, for example, an audio codec (codec). The microphone control chip can be connected to the processing in the electronic device and receive and process the transmitted microphone call signal. When the microphone control chip receives the calling signal, it can control the ASIC part of the microphone control circuit to control the microphone.

According to the embodiment of the present application, by applying a target voltage through the diaphragm and the back plate, the vibration of the diaphragm can be controlled to separate the base from the diaphragm support column, thereby adjusting the impurities at the connection to enter a fracture state. In this way, if an application needs to call the microphone during the process of turning on the screen, and obtain audio data through the microphone, the impact of impurity breakage on the normal vibration of the diaphragm can be avoided, and the generation of noise can be avoided.

In some embodiments, before detecting whether the screen of the electronic device is lit, the method includes: detecting whether the electronic device enables the voice wake-up function; detecting whether the screen of the electronic device is lit, specifically including: when the electronic device does not enable the voice wake-up function. , detect whether the screen of the electronic device is lit.

Specifically, the voice wake-up function in the electronic device can be used when the screen is in a screen-off state. Therefore, before detecting whether the screen of the electronic device is lit, it may be first detected whether the electronic device has enabled the voice wake-up function. When the electronic device does not enable the voice wake-up function, the target voltage has not been applied to the microphone of the electronic device. Next, determine whether the microphone is powered on by detecting whether the screen of the electronic device is lit.

According to embodiments of the present application, by combining the working status detection of the screen and the opening status of the voice wake-up function, the intention of the electronic device to call the microphone can be accurately identified. Especially when the voice wake-up function is turned on or the screen is detected to light up, a target voltage is applied to the microphone, so that the state of impurities can be quickly adjusted. In the subsequent use of the microphone, the impact of impurities on the normal vibration of the diaphragm can be effectively reduced and the generation of noise can be avoided.

In some embodiments, the target voltage is applied to the microphone when it is detected that the electronic device initiates the voice wake-up function.

In the embodiment of the present application, when it is detected that the electronic device activates the voice wake-up function, a target voltage is applied to the microphone to quickly adjust the state of the impurities. In the subsequent use of the microphone, the impact of impurities on the normal vibration of the diaphragm can be effectively reduced and the generation of noise can be avoided.

In some embodiments, after applying the target voltage to the microphone, the method further includes: stopping applying the target voltage to the microphone when it is detected that the screen of the electronic device is turned off and the microphone is not called by the target application.

Specifically, after applying the operating voltage to the microphone, the electronic device can continue to detect the display state of the screen. When the display state of the screen of the electronic device is screen off, the user may stop using the electronic device. When it is detected that the display state of the screen is screen off and the target application is not running, the application of operating voltage to the microphone may be stopped, that is, the microphone may be turned off. For example, the target application is an application in an electronic device that can call a microphone, such as a voice assistant application, a phone, a social networking application, etc., which are not listed here.

According to the application embodiment, by detecting the display status of the screen and the running status of the target application, the microphone is controlled to be turned on or off, thereby effectively reducing the running time of the microphone and reducing excess power consumption caused by the running of the microphone.

For the microphone control method provided by the embodiment of the present application, the execution subject may be a microphone control device.
