[0024] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0025] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0026] With the popularization of terminal technology, the application of terminal equipment is becoming more and more extensive. In the production process of terminal equipment, there are process operations such as welding and furnace passing. Therefore, impurities such as flux are inevitably introduced into the inside of the terminal equipment.

[0027] For a terminal device including a microphone, foreign matter may easily adhere to the vicinity of the diaphragm of the microphone after entering the microphone, so that during use of the microphone, the sticky state of the foreign matter may affect the normal vibration of the diaphragm of the microphone, thereby generating noise.

[0028] To this end, embodiments of the present application provide a control method, device, electronic device, and readable storage medium for a microphone. Specifically, after applying an operating voltage to the microphone, starting the microphone, and before using the microphone to obtain audio data, by applying a target voltage to the audio receiving unit in the microphone, the vibration amplitude of the diaphragm in the audio receiving unit can reach a target vibration amplitude. In the process of the diaphragm generating the target vibration amplitude, the impurities are adjusted to enter a fractured state. When the state of the impurities is a fractured state, the influence of the impurities on the normal vibration of the diaphragm can be effectively reduced to avoid generating noise.

[0029] The following describes in detail the microphone control method provided in the embodiment of the present application through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0030] Figure 1 1 is a flow chart of a microphone control method provided in an embodiment of the present application. Figure 1 As shown, the microphone control method may be applied to an electronic device including a microphone, and the method may include steps 110 to 120.

[0031] Step 110, detecting whether the screen of the electronic device is lit.

[0032] 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 laptop computer, a PDA, etc. During the operation of the microphone, the microphone may convert a sound signal into an electrical signal. Exemplarily, the types of microphones include, but are not limited to, dynamic, condenser, electret, and silicon micro-microphones. Specifically, after the microphone is started, an electrical signal corresponding to the sound signal may be obtained through the vibration of the diaphragm.

[0033] In some embodiments, during the manufacturing process of electronic devices, impurities such as solder flux are inevitably introduced into the interior of the electronic devices. For electronic devices including microphones, impurities entering the interior of the microphones are likely to stick to the vicinity of the diaphragm of the microphones. For example, solder flux volatilizes at high temperatures and enters the microphones, and is likely to accumulate near the diaphragm, thereby affecting the normal vibration of the diaphragm.

[0034] In order to reduce the impact of impurities on the normal vibration of the diaphragm, it is possible to determine whether the electronic device has the possibility of using the microphone by detecting the display state 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 the application that can call the microphone in the electronic device may also be turned on. Exemplary applications that call the microphone, such as voice assistant applications, telephones, social applications, etc., are not listed here one by one. When the application is running, the microphone can be called and audio data can be obtained through the microphone.

[0035] Step 120: When it is detected that the screen of the electronic device is turned on, a target voltage is applied to the microphone.

[0036] Specifically, when it is detected that the screen of the electronic device is turned on, a target voltage may be immediately applied to the microphone so that the diaphragm in the microphone vibrates in response to the target voltage.

[0037] As a specific example, taking a silicon micro-microphone as an example, the diaphragm and the back plate form the two poles of a parallel plate capacitor. When the diaphragm receives sound waves and vibrates, the distance between the diaphragm and the back plate changes, causing the capacitance of the parallel plate capacitor to change. Then, by collecting voltage fluctuations, the sound signal can be converted into an electrical signal. Based on this, by applying a certain voltage to the diaphragm, the diaphragm can be controlled to vibrate.

[0038] Since the sticking state of impurities on the diaphragm can be changed during the process of the diaphragm generating the target vibration amplitude, that is, in the embodiment of the present application, when it is detected that the screen of the electronic device is turned on, the target voltage is immediately applied to the microphone, so that the diaphragm can vibrate in advance before the microphone is called by the application program, so that in the subsequent use of the microphone, the influence of impurities on the normal vibration of the diaphragm is effectively reduced to avoid noise.

[0039] As a specific example, the microphone includes a diaphragm support column, a substrate and a back plate, the substrate is connected to the diaphragm through the diaphragm support column, and the back plate and the diaphragm form two poles of a capacitor; applying a target voltage to the microphone may specifically include: applying a target voltage to the diaphragm and the back plate, so that the diaphragm vibrates in response to the target voltage, and separating the diaphragm support column of the microphone from the base.

[0040] 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 the target voltage to the diaphragm and the back plate, the diaphragm can be pulled up by charge attraction, thereby controlling the separation of the diaphragm support column and the base and adjusting the adhesion state of impurities.

[0041] Figure 2 is a schematic diagram of the structure of a microphone provided in an embodiment of the present application. Figure 2 As shown, the microphone includes a diaphragm 201, a back plate 202, and a base 203. The base 203 is connected to the diaphragm 201 through a diaphragm support column, that is, the diaphragm is arranged on the base through the diaphragm support column. The diaphragm 201 and the back plate 202 form a capacitor. Figure 3 FIG. 1 is a schematic diagram of the structure of another microphone provided by an embodiment of the present application. Figure 3 As shown, the base and the diaphragm include a diaphragm support column 301 and a diaphragm support column 302. In a natural static state, the relationship between the diaphragm 201 and the base 203 is as follows: Figure 3 In the vibrating state, if there is no impurity adhering to the position where the diaphragm support column and the base contact each other, the diaphragm 201 moves upward to lift the diaphragm support column. The relationship between the diaphragm 201 and the base 203 is as shown in FIG. Figure 3 (b) as shown.

[0042] For a terminal device including a microphone, after foreign matter enters the interior of the microphone, the foreign matter may adhere to the position where the diaphragm support column and the base contact each other. Figure 4 Schematic diagram of impurity adhesion provided by an embodiment of the present application. Figure 4 (a) shows the sticky state 401 of the impurity. During the operation of the microphone, the diaphragm will vibrate in response to the sound signal. For example, solder flux has impurities with strong viscosity. During the vibration of the diaphragm, the sticky state 402 of the impurity is as follows: Figure 4 As shown in (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, but during the continuous vibration of the diaphragm, as the diaphragm stretches, the sticky impurities will eventually break off. At this time, the instantaneous inertia will cause the diaphragm to produce a rapid displacement in an extreme time, and the impurities will enter a broken state 403, as shown in FIG. Figure 4 (c) as shown.

[0043] Since the diaphragm and the back plate form a capacitor, combined with the expression formula (1) of the capacitance C of the parallel plate capacitor

[0044]

[0045] Among them, S represents the area of ​​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.

[0046] Therefore, when the instantaneous inertia causes the diaphragm to produce a rapid displacement d in an extreme time, the capacitance value will be instantly reduced. Combined with U=Q / C, where U is the voltage and Q is the charge. When the capacitance value is instantly reduced, the voltage will jump, which will cause noise during the use of the microphone. If the diaphragm returns to its natural static state within a period of time, the sticky impurities will be re-adsorbed, causing noise to still be generated during the next use of the microphone.

[0047] In the embodiment of the present application, when it is detected that the screen of the electronic device is turned on, the target voltage is immediately applied to the microphone, so that the diaphragm can vibrate in advance before the microphone is called by the application program each time, driving the separation of the diaphragm support column and the base. That is, the impurities between the diaphragm support column and the base are separated in advance. Figure 4 (c) shows the broken state 403. Based on this, in the subsequent use of the microphone, since the impurities have entered the broken state 403, the influence of the impurities on the normal vibration of the diaphragm is effectively reduced during the subsequent operation of the microphone, and noise can be avoided.

[0048] Figure 5 is a schematic diagram of the structure of a microphone control circuit provided in an embodiment of the present application. Figure 5As shown, the microphone control circuit may include a micro-electro-mechanical system (MEMS) acoustic part and an application specific integrated circuit (ASIC) part. The microphone may be provided with voltage through VDD1, and then the target voltage may be applied to the audio control unit through a charge pump control circuit.

[0049] Optionally, a separate microphone control chip, such as an audio codec, may be provided in the electronic device. The microphone control chip may be connected to a processor in the electronic device and receive and process a sent microphone call signal. When the microphone control chip receives the call signal, it may control the ASIC part of the microphone control circuit to control the microphone.

[0050] According to the embodiment of the present application, by applying the target voltage through the diaphragm and the back plate, the base and the diaphragm support column can be separated by controlling the vibration of the diaphragm, thereby adjusting the impurities at the connection to enter a broken state. In this way, if an application needs to call the microphone during the screen lighting process, the microphone can be used to obtain audio data, which can avoid the influence of the impurity break on the normal vibration of the diaphragm and avoid noise.

[0051] In some embodiments, before detecting whether the screen of the electronic device is lit, the method includes: detecting whether the voice wake-up function of the electronic device is enabled; detecting whether the screen of the electronic device is lit, specifically including: detecting whether the screen of the electronic device is lit when the voice wake-up function is not enabled.

[0052] Specifically, the voice wake-up function in the electronic device can be used when the screen is in the off state. Therefore, before detecting whether the screen of the electronic device is lit, it is possible to first detect whether the electronic device has the voice wake-up function enabled. When the electronic device does not have the voice wake-up function enabled, the microphone of the electronic device has not applied the target voltage. Next, by detecting whether the screen of the electronic device is lit, it is determined whether the microphone is powered on.

[0053] According to the embodiment of the present application, by combining the working state detection of the screen and the opening state of the voice wake-up function, the intention of the electronic device to call the microphone can be accurately identified. In particular, when the voice wake-up function is turned on or the screen is detected to be lit, the target voltage is applied to the microphone, so that the state of the impurities can be quickly adjusted. In the subsequent use of the microphone, the influence of the impurities on the normal vibration of the diaphragm can be effectively reduced to avoid noise.

[0054] In some embodiments, when it is detected that the electronic device activates a voice wake-up function, a target voltage is applied to the microphone.

[0055] In the embodiment of the present application, when it is detected that the electronic device starts 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 influence of the impurities on the normal vibration of the diaphragm can be effectively reduced to avoid noise.

[0056] In some embodiments, after applying the target voltage to the microphone, the method further includes: when it is detected that the screen of the electronic device is turned off and the microphone is not called by the target application, stopping applying the target voltage to the microphone.

[0057] Specifically, after applying the operating voltage to the microphone, the electronic device may continue to detect the display state of the screen. When the display state of the screen of the electronic device is the screen off, the user may stop using the electronic device. When it is detected that the display state of the screen is the screen off and the target application is not running, the operating voltage can be stopped from being applied to the microphone, that is, the microphone is turned off. Exemplarily, the target application is an application in the electronic device that can call the microphone, such as a voice assistant application, a phone, a social application, etc., which are not listed here one by one.

[0058] 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 the excess power consumption caused by the operation of the microphone.

[0059] The microphone control method provided in the embodiment of the present application can be executed by a microphone control device. In the embodiment of the present application, the microphone control method performed by the microphone control device is taken as an example to illustrate the microphone control device provided in the embodiment of the present application.

[0063] In an embodiment of the present application, for an electronic device including a microphone, the electronic device detects whether the screen is lit, and when the screen is detected to be lit, applies a target voltage to the microphone. After the target voltage is applied to the microphone, the vibration of the diaphragm in the microphone can vibrate in response to the target voltage. Since the stickiness of impurities to the diaphragm can be changed during the process of the diaphragm generating the target vibration amplitude, the influence of impurities on the normal vibration of the diaphragm can be effectively reduced during the subsequent use of the microphone, thereby avoiding the generation of noise.

[0064] In some embodiments, the detection module 610 is further used to detect whether the electronic device has enabled the voice wake-up function;

[0065] The detection module 610 is also used to detect whether the screen of the electronic device is lit when the voice wake-up function of the electronic device is not enabled.

[0066] According to the embodiment of the present application, by combining the working state detection of the screen and the opening state of the voice wake-up function, the intention of the electronic device to call the microphone can be accurately identified.

[0067] In some embodiments, the control module 620 is further configured to apply a target voltage to the microphone when it is detected that the electronic device starts a voice wake-up function.

[0068] In the embodiment of the present application, when it is detected that the electronic device starts 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 influence of the impurities on the normal vibration of the diaphragm can be effectively reduced to avoid noise.

[0069] In some embodiments, the control module 620 is further configured to stop 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.

[0070] 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 the excess power consumption caused by the operation of the microphone.

[0071] In some embodiments, the microphone further includes a diaphragm support column, a substrate and a back plate, the substrate is connected to the diaphragm through the diaphragm support column, and the back plate and the diaphragm form two poles of a capacitor;

[0072] The control module 620 is also used to apply a target voltage to the diaphragm and the back plate, so that the diaphragm vibrates in response to the target voltage and separates the diaphragm support column of the microphone from the base.

[0073] According to the embodiment of the present application, by applying the target voltage through the diaphragm and the back plate, the base and the diaphragm support column can be separated by controlling the vibration of the diaphragm, thereby adjusting the impurities at the connection to enter a broken state. In this way, if an application needs to call the microphone during the screen lighting process, the microphone can be used to obtain audio data, which can effectively avoid the influence of the impurity break on the normal vibration of the diaphragm and avoid noise.

[0085] In an embodiment of the present application, for an electronic device including a microphone, the electronic device detects whether the screen is lit, and when the screen is detected to be lit, applies a target voltage to the microphone. After the target voltage is applied to the microphone, the vibration of the diaphragm in the microphone can vibrate in response to the target voltage.
