Description

Driving voltage adjusting method, electronic device and storage medium

Technical Field

The present disclosure relates to the field of terminal technologies, and in particular, to a method for adjusting a driving voltage and an electronic device.

Background

With the development of electronic technology, electronic devices such as mobile phones are equipped with camera modules, and the functions of shooting and recording videos of the mobile phones are realized through the camera modules.

Generally, a motor is provided inside a mobile phone, and a driving voltage is applied to the motor to cause vibration of the mobile phone. For a camera module without damping glue, when a motor inside a mobile phone vibrates, the resonant frequency of the motor coincides with or is close to the bivalent resonant frequency and the trivalent resonant frequency of a lens in the camera module, so that resonance is caused, the lens frequently collides with a shell of the mobile phone, and abnormal sound is generated.

At present, in order to avoid causing resonance, the driving voltage of the motor is uniformly reduced, and the overall vibration sense is further reduced. However, the occurrence of resonance is a probabilistic event, and therefore, the mobile phone that does not cause resonance will sacrifice some performance by uniformly reducing the driving voltage of the motor, for example, the vibration provided by some mobile phones will be weak and difficult for the user to perceive.

Disclosure of Invention

The application provides a driving voltage adjusting method and electronic equipment, which can reduce performance sacrifice.

In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, the present application provides a method for adjusting a driving voltage, which applies an electronic device, and includes that the electronic device controls a motor of the whole machine to start vibrating by using a first driving voltage, acquires an audio through a microphone to obtain a first audio, then controls the motor of the whole machine to stop vibrating, and acquires the audio through the microphone again to obtain a second audio, that is, acquires the first audio during the vibration of the motor of the whole machine and the second audio during the non-vibration of the motor of the whole machine. And then, the electronic equipment compares the first audio frequency with the second audio frequency to obtain an audio frequency comparison result, if the audio frequency comparison result represents that the electronic equipment has resonance abnormal sound, the voltage value of the first driving voltage is reduced, then the first driving voltage with the reduced voltage value returns to the step of controlling the whole motor to start vibration by using the first driving voltage, namely, the process of audio frequency comparison acquired by audio frequency is executed in a circulating manner until the obtained audio frequency comparison result represents that the electronic equipment has no second driving voltage when the resonance abnormal sound, and the second driving voltage is used as the driving voltage of the whole motor.

In the method, the electronic equipment independently tests the driving voltage of the whole motor of the electronic equipment until the driving voltage adaptive to the electronic equipment is obtained, and then the driving voltage adaptive to the electronic equipment is utilized to drive the whole motor, so that the performance sacrifice can be reduced, and the occurrence of resonance abnormal sound can be avoided.

In some possible implementations, the driving voltage may be further modified by an image based on the above-mentioned determination of the driving voltage adapted to the driving voltage by audio frequency. Specifically, the electronic device may further control the whole machine motor to start vibrating by using the second driving voltage determined by the audio frequency, obtain a first image by imaging through the camera, then control the whole machine motor to stop vibrating, obtain a second image by imaging through the camera, that is, acquire and obtain the first image in the vibrating process of the whole machine motor and the second image in the non-vibrating process of the whole machine motor. And then the electronic equipment compares the first image with the second image to obtain an image comparison result, if the image comparison result represents that the electronic equipment is out of focus, the voltage value of the second driving voltage is reduced, then the second driving voltage with the reduced voltage value returns to execute the step of controlling the motor of the whole machine to start vibration by using the second driving voltage, namely, the process of comparing the image collected by the image is circularly executed until the obtained image comparison result represents that the electronic equipment is not out of focus by using the third driving voltage. The second driving voltage is used as the driving voltage of the complete machine motor, and specifically, the third driving voltage may be used as the driving voltage of the complete machine motor.

In the method, the electronic equipment corrects the driving voltage of the whole motor again, so that the corrected driving voltage can be matched with the electronic equipment more, and the performance sacrifice is further reduced.

In some possible implementation manners, the electronic device may reduce the voltage value of the first driving voltage by using a 2-division method, and a process of reducing the voltage value of the first driving voltage by the electronic device may be considered as a coarse adjustment process, that is, the electronic device reduces the driving voltage of the motor of the whole machine to an approximate range without resonance abnormal sound, so that efficiency of adjusting the voltage can be improved.

In some possible implementations, the electronic device may determine the audio comparison result based on peak-to-peak characteristics of the first audio and the second audio, for example, if the first audio includes a peak-to-peak characteristic compared to the second audio, obtain an audio comparison result with a resonance abnormal sound; and if the first audio frequency does not comprise the peak-to-peak value characteristic compared with the second audio frequency, obtaining an audio frequency comparison result without resonance abnormal sound. In which the effect of noise (e.g., environmental sound) on the audio comparison result can be excluded by comparing the first audio with the second audio, in some examples, the signal of the first audio may be subtracted from the signal of the second audio, and then based on the subtracted signal, it is determined whether the first audio includes a peak-to-peak feature compared with the second audio, so as to improve the accuracy of the comparison.

In some possible implementations, the electronic device may reduce the voltage value of the second driving voltage by using a step size standard value that is at least twice, and it may be considered that the process of reducing the voltage value of the second driving voltage by the electronic device is a fine adjustment process, that is, the second driving voltage is adjusted to a more precise value, that is, to a third driving voltage, in an approximate range, so that the driving voltage (that is, the third driving voltage) of the complete machine motor is more matched with the electronic device, and performance sacrifice is reduced.

For example, the electronic device may perform a reduction process on the voltage value of the second driving voltage by using a compensation standard value of 3 times, so as to reduce the number of cycles of the cyclic processing process, thereby further improving the adjustment efficiency.

Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

For clarity and conciseness of the description of the embodiments described below, a brief introduction of the related art is first given.

A Camera Module (CCM) generally includes: lens (lens), image sensor (image sensor), flexible Printed Circuit (FPC), image Processing chip (DSP). The camera lens, the sensor and the image processing chip can determine the quality of the camera module.

For some camera modules which are not provided with damping glue, in the vibration process of a whole motor and under the condition that the camera modules are not electrified to work, the resonance frequency of the whole motor can coincide with or approach to the divalent resonance frequency and the trivalent resonance frequency of a lens to cause resonance, so that the lens can collide with the shell of the mobile phone or other positions inside the mobile phone to generate abnormal sound, and meanwhile, the lens can be damaged to influence the subsequent imaging effect.

In view of this, an embodiment of the present application provides an electronic device, where the electronic device may be a mobile phone, a tablet computer, or the like, and the specific form of the electronic device is not particularly limited in the present application. The electronic equipment can search the driving voltage adaptive to the electronic equipment through independent test, so that the whole motor is driven by the driving voltage.

For example, in the present application, the method and the device can be used to trigger a vibration starting instruction and a vibration stopping instruction, so as to control a motor of the whole machine to start vibration, stop vibration, and the like, and can also be used to trigger a sound receiving instruction and an imaging instruction, so as to control the microphone 170C to collect audio, control the camera 193 to collect images, and perform audio/image ratio and the like.

The controller can be a neural center and a command center of the electronic device. The controller can generate an operation control signal according to the instruction operation code and the timing signal to complete the control of instruction fetching and instruction execution.

A memory may also be provided in processor 110 for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may hold instructions or data that have just been used or recycled by the processor 110. If the processor 110 needs to reuse the instruction or data, it can be called directly from the memory. Avoiding repeated accesses reduces the latency of the processor 110, thereby increasing the efficiency of the system.

In some embodiments, processor 110 may include one or more interfaces. The interface may include an integrated circuit (I2C) interface, a Mobile Industry Processor Interface (MIPI), a general-purpose input/output (GPIO) interface, and/or a Universal Serial Bus (USB) interface, etc.

In some embodiments, the processor 110 may include multiple sets of I2C buses. The processor 110 may be coupled to the charger, the flash, the camera 193, etc. through different I2C bus interfaces, respectively. For example: the processor 110 may be coupled to the motor 191 through an I2C interface, so that the processor 110 and the motor 191 communicate through an I2C bus interface to implement a vibration function of the electronic device.

The electronic device may implement a shooting function through the ISP, the camera 193, the video codec, the GPU, and the application processor, etc.

The ISP is used to process the data fed back by the camera 193. For example, when a photo is taken, the shutter is opened, light is transmitted to the camera photosensitive element through the lens, the optical signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing and converting into an image visible to naked eyes. The ISP can also carry out algorithm optimization on noise, brightness and skin color of the image. The ISP can also optimize parameters such as exposure, color temperature and the like of a shooting scene. In some embodiments, the ISP may be provided in camera 193.

The camera 193 is used to capture still images or video. The object generates an optical image through the lens and projects the optical image to the photosensitive element. The photosensitive element may be a Charge Coupled Device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then transmits the electrical signal to the ISP to be converted into a digital image signal. And the ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into image signal in standard RGB, YUV and other formats. In some embodiments, the electronic device may include 1 or N cameras 193, N being a positive integer greater than 1. In some embodiments, camera 193 may be a camera module.

The internal memory 121 may be used to store computer-executable program code, which includes instructions.

In addition, the internal memory 121 may include a high-speed random access memory, and may further include a nonvolatile memory, such as at least one magnetic disk storage device, a flash memory device, a universal flash memory (UFS), and the like. The processor 110 executes various functional applications of the electronic device and data processing by executing instructions stored in the internal memory 121 and/or instructions stored in a memory provided in the processor.

The electronic device may implement audio functions through the audio module 170, the speaker 170A, the microphone 170C, and the application processor, etc. Such as music playing, recording, etc.

In some embodiments, the audio module 170 may be disposed in the processor 110, or some functional modules of the audio module 170 may be disposed in the processor 110.

The speaker 170A, also called a "horn", is used to convert the audio electrical signal into an acoustic signal. The electronic device can listen to music through the speaker 170A or listen to a hands-free call.

The microphone 170C, also referred to as a "microphone," is used to convert sound signals into electrical signals. When making a call or transmitting voice information, the user can input a voice signal to the microphone 170C by speaking near the microphone 170C through the mouth. The electronic device may be provided with at least one microphone 170C. In other embodiments, the electronic device may be provided with two microphones 170C to achieve a noise reduction function in addition to collecting sound signals. In other embodiments, the electronic device may further include three, four or more microphones 170C to collect sound signals, reduce noise, identify sound sources, and implement directional recording functions.

The motor 191 may generate a vibration cue. The motor 191 may be used for incoming call vibration prompts as well as for touch vibration feedback. For example, touch operations applied to different applications (e.g., photographing, audio playing, etc.) may correspond to different vibration feedback effects. The motor 191 may also respond to different vibration feedback effects for touch operations applied to different areas of the display screen. Different application scenes (such as time reminding, receiving information, alarm clock, game and the like) can also correspond to different vibration feedback effects. The touch vibration feedback effect may also support customization.

The operating system of the electronic device may employ a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The embodiment of the application takes an Android system with a layered architecture as an example, and exemplarily illustrates a software structure of an electronic device.

Fig. 2B is a block diagram of a software structure of an electronic device according to an embodiment of the present application.

The layered architecture divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, which are an application Layer (Applications), a Framework Layer (Framework), a Hardware Abstraction Layer (HAL), and a Kernel Layer (Kernel), from top to bottom.

The application layer may include a series of application packages. As shown in fig. 2B, the application package may include camera, gallery, calendar, call, map, navigation, WLAN, bluetooth, music, video, short message, etc. applications. The framework layer provides an Application Programming Interface (API) and a programming framework for the application programs of the application layer. The framework layer includes some predefined functions. As shown in FIG. 2B, the application framework layers may include a window manager, content provider, view system, phone manager, resource manager, notification manager, and the like. The hardware abstraction layer defines an interface of a hardware 'driver' and reduces the coupling degree of an android operating system and hardware. The kernel layer is responsible for managing the processes, memories, device drivers, files and network systems of the system, and determining the performance and stability of the system. The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver, a sensor driver, a motor driver and the like.

Although the Android system is taken as an example in the embodiment of the present application for description, the basic principle is also applicable to electronic devices based on operating systems such as iOS and Windows.

For ease of understanding, the electronic device is taken as a mobile phone, and is described below. As shown in fig. 3, which is a software interaction diagram provided in an embodiment of the present application, the method for adjusting the driving voltage may include:

s301, transmitting a vibration starting command carrying a first driving voltage to the X-axis motor drive of the inner core layer by the test application.

The test application may be an application program in the application layer, and is used to test the mobile phone to determine a voltage value of the driving voltage corresponding to the mobile phone.

The test application may receive a user-triggered command and then transmit a start vibration command carrying a first drive voltage to a motor drive (e.g., an X-axis motor drive) of the core layer. Of course, in other embodiments, the test application may also receive a test command sent by another device (e.g., a test device), and then transmit a start vibration command carrying the first driving voltage to the motor driver of the core layer. The test application of the application layer can transmit the vibration starting instruction to the motor drive of the kernel layer through the framework layer and the hardware abstraction layer.

And S302, controlling the motor of the whole machine to start to vibrate by the X-axis motor drive according to the vibration starting instruction.

After the motor drive obtains the vibration starting instruction, the voltage value of the first driving voltage carried in the vibration starting instruction can be analyzed, and then the motor of the whole machine is controlled to start vibration based on the voltage value of the first driving voltage.

S303, the test application sends a radio receiving instruction to the audio driver of the kernel layer.

Then, the test application may send a radio reception instruction to the audio driver of the kernel layer, and similarly, the test application of the application layer may transparently transmit the radio reception instruction to the audio driver of the kernel layer through the framework layer and the hardware abstraction layer.

S304, the audio driver controls the microphone to collect audio according to the sound receiving instruction to obtain first audio.

The audio driver controls the microphone to collect audio based on the radio receiving instruction. For example, a mobile phone can be placed in a sound shielding box to isolate external audio interference, and then a first audio frequency in the vibration process of the whole motor is obtained.

S305, the test application acquires a first audio.

After the audio acquisition is completed, the first audio may be transmitted to a test application of the application layer, and the test application obtains the first audio.

S306, transmitting a stop vibration instruction to the X-axis motor drive of the inner core layer by the test application.

The test application transmits a vibration stopping instruction to the motor drive of the inner core layer so as to stop the vibration of the motor of the whole machine, and subsequent audio comparison is facilitated. Similarly, the test application of the application layer can transmit the stop vibration instruction to the motor drive of the kernel layer through the framework layer and the hardware abstraction layer.

And S307, controlling the motor of the whole machine to stop vibrating according to the vibration stopping instruction by driving the X-axis motor.

And after the motor drive acquires the vibration stopping instruction, controlling the motor of the whole machine to stop vibrating.

S308, the test application sends a radio receiving instruction to the audio driver of the kernel layer.

And S309, controlling the microphone to collect the audio by the audio driver according to the radio receiving instruction to obtain a second audio.

Similarly, the audio driver controls the microphone to collect audio based on the sound receiving instruction. For example, the mobile phone can be placed in the sound shielding box to isolate external audio interference, so that a second audio in the vibration process of the whole motor is obtained.

S310, the test application acquires a second audio.

After the acquisition of the audio is completed, the second audio may be transmitted to a test application for the application layer, which obtains the second audio.

It should be noted that, the test application may also acquire the first audio and the second audio together after the microphone finishes acquiring the second audio.

S311, the test application judges whether abnormal sound exists according to the first audio and the second audio, if yes, S312 is executed, and if not, S313 is executed.

After the test application acquires the first audio and the second audio, whether abnormal sound exists or not may be determined based on signal characteristics of the first audio and the second audio, for example, whether abnormal sound exists or not may be determined based on a peak-to-peak value of vibration regularity of the first audio and the second audio. As shown in fig. 4A and fig. 4B, fig. 4A is a signal characteristic of the presence of abnormal noise provided by the embodiment of the present application, and fig. 4B is a signal characteristic of the absence of abnormal noise provided by the embodiment of the present application. As can be seen from fig. 4A and 4B, the signal characteristic in fig. 4A has a distinct peak-to-peak value compared to the signal characteristic in fig. 4B, and as the signal in fig. 4A and 4B is subjected to difference processing, a distinct peak-to-peak value characteristic can be obtained.

And S312, reducing the voltage value of the first driving voltage by adopting a 2-minute method in the test application, and returning to S301 until a second driving voltage without any noise is obtained.

After the test application determines that abnormal sound exists, the voltage value of the first driving voltage can be roughly adjusted by sampling a 2-division method, then the step returns to S301, the first driving voltage after the voltage value is roughly adjusted is used for driving the motor of the whole machine, and then the steps from S301 to S312 are repeated until a second driving voltage without abnormal sound is obtained. The voltage value of the second driving voltage is smaller than the initial voltage value of the first driving voltage. At this time, the second driving voltage may be used as a driving voltage of a motor of the electronic device.

And S313, transmitting a vibration starting command carrying a second driving voltage to the X-axis motor drive of the inner core layer by the test application.

The test application may then transmit a start vibration command carrying a second drive voltage to the motor drive of the core layer. Similarly, the test application at the application layer may pass through the start vibration command to the motor driver at the kernel layer through the framework layer and the hardware abstraction layer.

And S314, controlling the motor of the complete machine to start vibrating according to the vibration starting command by driving the X-axis motor.

After the motor drive obtains the vibration starting command, the voltage value of the second driving voltage carried in the vibration starting command can be analyzed, and then the complete machine motor is controlled to start vibration based on the voltage value of the second driving voltage.

And S315, sending an imaging instruction to the camera driver of the kernel layer by the test application.

Then, the test application may send an imaging instruction to the camera driver of the kernel layer, and similarly, the test application of the application layer may transmit the imaging instruction to the camera driver of the kernel layer through the framework layer and the hardware abstraction layer.

And S316, controlling the camera to collect images by the camera drive according to the imaging instruction to obtain a first image.

The camera drive controls the camera to collect images based on the imaging instruction, and a first image is obtained. Continuing with the above example, a reference image may be placed in the sound shield box to be photographed. Fig. 5 is a schematic diagram of a reference image according to an embodiment of the present application.

S317, the test application acquires a first image.

After the acquisition of the image is completed, the first image may be transmitted to a test application of the application layer, and the test application acquires the first image.

S318, transmitting a stop vibration instruction to the X-axis motor drive of the inner core layer by the test application.

And the test application transmits a vibration stopping instruction to the motor drive of the inner core layer so as to stop the vibration of the motor of the whole machine, thereby facilitating the subsequent image comparison. Similarly, the test application of the application layer can transmit the stop vibration instruction to the motor drive of the kernel layer through the framework layer and the hardware abstraction layer.

And S319, controlling the motor of the complete machine to stop vibrating according to the vibration stopping command by driving the X-axis motor.

After the acquisition of the image is completed, the second image may be transmitted to a test application for the application layer, which obtains the second image.

And S323, judging whether the focusing imaging is influenced or not by the test application according to the first image and the second image, if so, executing S324, and otherwise, executing S325.

The test application may determine whether vibration of the complete machine motor has an influence on the focus imaging based on the first image and the second image. The out-of-focus image differs from the in-focus image in whether the outline edges of the image are apparent, the in-focus image is apparent, and the out-of-focus image has no variation between large pixel values. In some embodiments, a first difference value of adjacent pixels in the first image may be calculated, and then all of the first difference values corresponding to the first image may be summed to obtain a first sum value, and similarly, the second image may be processed similarly, e.g., a second difference value of adjacent pixels in the second image may be calculated, and then all of the second difference values corresponding to the second image may be summed to obtain a second sum value. Then comparing the first sum value with the second sum value, and if the first sum value is smaller than the second sum value, indicating that the defocusing exists; if the first sum is greater than or equal to the second sum, it indicates that there is no defocus.

After the test application determines that the vibration of the motor of the whole machine affects the focusing imaging, the voltage value of the second driving voltage can be finely adjusted by adopting the step standard value. For example, the step size criterion value may be 0.1V, 0.05V, etc. In some examples, the step size criterion value can be set to a smaller value, such as 0.05V, when improved adjustment accuracy is desired. On the basis, in order to further increase the adjustment speed, the voltage value of the second driving voltage can be adjusted by adopting the step size standard value which is 2 times (0.1V), 3 times (0.15V) or more. And returning to S313, driving the motor of the whole machine by using the second driving voltage with the finely adjusted voltage value, and repeating the steps from S313 to S324 until a third driving voltage which does not influence the focusing imaging is obtained. Wherein, the voltage value of the third driving voltage is smaller than the initial voltage value of the second driving voltage.

In this way, for the mobile phone, the third voltage value obtained by the coarse adjustment and the fine adjustment can be used as the driving voltage of the motor of the whole mobile phone. Therefore, the third driving voltage is used for driving the motor of the whole mobile phone, and in the vibration process of the mobile phone, the energy transmitted to the position of the camera module is smaller than the energy causing the resonant abnormal sound, so that the resonance can be avoided, and the abnormal sound is avoided. Therefore, in the application, each mobile phone adopts independent driving voltage to drive the motor of the whole mobile phone, namely, the vibration of each mobile phone is independently reduced, the vibration of the motor is not wasted, the waste of the performance of the mobile phone is reduced, and the user experience is improved.
