Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

The display screen generally plays a role in an electronic device such as a mobile phone or a tablet computer to display text, pictures, icons, or video. With the development of touch technologies, more and more display screens arranged in electronic devices are touch display screens, and when a user is detected to perform touch operations such as dragging, clicking, double clicking, sliding and the like on the touch display screen, the touch operations of the user can be responded under the condition of arranging the touch display screens.

As the user demands higher definition and higher fineness of the displayed content, more electronic devices employ touch display screens with larger sizes. However, in the process of setting a touch display screen with a large size, it is found that functional devices such as a front camera, a proximity optical sensor, and a receiver, which are disposed at the front end of the electronic device, affect an area that the touch display screen can extend to.

Generally, an electronic device includes a front panel, a rear cover, and a bezel. The front panel includes a forehead area, a middle screen area and a lower key area. Generally, the forehead area is provided with a sound outlet of a receiver and functional devices such as a front camera, the middle screen area is provided with a touch display screen, and the lower key area is provided with one to three physical keys. With the development of the technology, the lower key area is gradually cancelled, and the physical keys originally arranged in the lower key area are replaced by the virtual keys in the touch display screen.

The earphone sound outlet holes arranged in the forehead area are important for the function support of the mobile phone and are not easy to cancel, so that the difficulty in expanding the displayable area of the touch display screen to cover the forehead area is high. After a series of researches, the inventor finds that sound can be emitted by controlling the screen, the frame or the rear cover of the mobile phone to vibrate, so that the arrangement of the sound outlet hole of the receiver can be eliminated.

Referring to fig. 1 and 2, an electronic device 100 according to an embodiment of the present application is shown. Fig. 1 is a front view of the electronic device, and fig. 2 is a side view of the electronic device.

The electronic device 100 comprises an electronic body 10, wherein the electronic body 10 comprises a housing 12 and a screen 120 disposed on the housing 12, the housing 12 comprises a front panel 125, a rear cover 127 and a bezel 126, the bezel 126 is used for connecting the front panel 125 and the rear cover 127, and the screen 120 is disposed on the front panel 125.

The electronic device further comprises an exciter 131, wherein the exciter 131 is used for driving a vibration component of the electronic device to vibrate, specifically, the vibration component is at least one of the screen 120 or the housing 12 of the electronic device, that is, the vibration component can be the screen 120, the housing 12, or a combination of the screen 120 and the housing 12. As an embodiment, when the vibration member is the housing 12, the vibration member may be a rear cover of the housing 12.

In the embodiment of the present application, the vibration component is the screen 120, and the exciter 131 is connected to the screen 120 for driving the screen 120 to vibrate. In particular, the actuator 131 is attached below the screen 120, and the actuator 131 may be a piezoelectric driver or a motor. In one embodiment, actuator 131 is a piezoelectric actuator. The piezoelectric actuator transmits its own deformation to the screen 120 by a moment action, so that the screen 120 vibrates to generate sound. The screen 120 includes a touch screen 109 and a display panel 111, the display panel 111 is located below the touch screen 109, and the piezoelectric driver is attached below the display panel 111, i.e., a side of the display panel 111 away from the touch screen 109. The piezoelectric driver includes a plurality of piezoelectric ceramic sheets. When the multilayer piezoelectric ceramic piece produces sound and expands and contracts, the screen is driven to bend and deform, and the whole screen forms bending vibration repeatedly, so that the screen can push air and produce sound.

As an embodiment, the electronic device 100 includes a detection circuit and a driving circuit, the detection circuit is used for determining whether a vibration parameter of a screen sounding area meets a preset condition; and if the preset conditions are met, adjusting the vibration parameters of the screen sounding area.

The exciter 131 is connected to a driving circuit of the electronic device, and the driving circuit is configured to input a control signal value according to the vibration parameter to the exciter 131, so as to drive the exciter 131 to vibrate, thereby driving the vibrating component to vibrate. In particular, the driving circuit may be a processor of the electronic device, or may be an integrated circuit capable of generating a driving voltage or current within the electronic device. The driving circuit outputs a high-low level driving signal to the exciter 131, the exciter 131 vibrates according to the driving signal, and the different electrical parameters of the driving signal output by the driving circuit may cause the different vibration parameters of the exciter 131, for example, the duty ratio of the driving signal corresponds to the vibration frequency of the exciter 131, and the amplitude of the driving signal corresponds to the vibration amplitude of the exciter 131.

In the embodiment of the present application, the plurality of actuators 131 may be uniformly distributed on the screen 120, so that the screen 120 is divided into a plurality of areas for sounding independently. For example, if the number of the actuators is 4, the screen may be divided into 4 square areas along the center line in the vertical direction and the center line in the horizontal direction, the 4 actuators are disposed below the 4 square areas, and the 4 actuators correspond to the 4 square areas one by one. Of course, the number of actuators is not limited in the embodiments of the present application.

Since the screen is vibrating to produce sound, the vibration parameters of each exciter may be different, wherein the vibration parameters include vibration frequency and vibration amplitude. Some vibration regions may vibrate above a threshold, e.g., vibrate too much or too quickly, may cause damage to the screen and may affect the quality of the sound produced. Therefore, in order to solve the technical problem, an embodiment of the present application provides a sound emission control method, as shown in fig. 3, for ensuring the quality of sound when a screen vibrates to emit sound, specifically, the method includes: s301 to S303.

S301: when the electronic device is detected to be in a screen sound production mode, determining whether the vibration parameters of the screen sound production area meet preset conditions.

The screen of the electronic device is used for vibration sound production and is suitable for a non-earphone call mode of the electronic device, wherein the non-earphone call mode comprises a listening-free mode and a receiver mode and is used for playing voice signals sent by the electronic device under the conditions of call, video playing and the like. Specifically, whether the terminal is currently in the screen sound emission mode or not can be determined by detecting the operation of the application program of the mobile terminal by the user, and specifically, the electronic device is in the screen sound emission mode, which can be receiving a sound emission request. The sound production request indicates the mobile terminal for the user, and the information that the screen needs to be controlled to vibrate and produce sound is required. In one embodiment, the sound production request may be a reminder message or a voice playing request.

The reminding information comprises information for reminding a user that some events are triggered, such as call reminding information, short message reminding information, alarm reminding information and the like. For example, the call reminding information is used for reminding the user that there is an incoming call currently, and the electronic device may enter a screen sound emission mode after the reminding information is acquired and before the electronic device does not emit sound, that is, the electronic device is in a state of waiting for sound emission at this time. Then, after the vibration parameters are acquired, the screen is controlled to vibrate and sound, so that a sound for reminding, such as a ringtone, is emitted.

As another embodiment, the utterance request may be a request to play a voice every time during the utterance of the mobile terminal. The method provided by the embodiment of the application is used for collecting the environmental noise to adjust the vibration of the vibration component in the sound production process of the mobile terminal, so as to adjust the sound production.

For example, the user clicks a play button of a certain video APP, and the electronic device is not currently in a mute state, and when detecting that the play button is triggered, the electronic device enters a screen vibration sound production mode, and plays a video voice through the vibration of the screen.

When the electronic device calls, namely the telephone ring or the vibration reminding rings, the electronic device can detect and display a call interface on a screen. And the user clicks an answering key in the incoming call interface to establish call connection between the current number of the SI M card of the electronic device and the incoming call number. Specifically, the phone state of the electronic device may be monitored through a phone manager within a system of the electronic device, thereby enabling monitoring whether the electronic device is in a talk mode. The phone manager is an application module in the system of the electronic device, and the user obtains the call status of the electronic device, for example, when the system of the electronic device is an android system, the phone manager is Te l ephenymanager.

Whether the electronic device is connected with the earphone or not is judged, specifically, the judgment can be carried out by checking the state of the earphone connecting hole of the electronic device, for example, when the earphone connecting hole of the electronic device is connected with the earphone, a first state value is returned, when the earphone in the connecting hole is pulled out, a second state value is returned, and whether the electronic device is connected with the earphone or not can be determined by detecting the first state value and the second state value. Specifically, the android system transmits a broadcast when the headset is plugged in and unplugged, so that the electronic device can determine whether the headset is currently connected to the electronic device by monitoring the broadcast. Thus, it can be determined whether the electronic device is in the headset talk mode.

Therefore, when the electronic device is determined to be currently playing voice and not to be muted and is not in the earphone call mode, the electronic device is determined to be in the screen sound production mode. Of course, as described above, if the screen is driven to vibrate by the exciter to make the screen vibrate to sound, the electronic device may be determined to be in the screen sound emission mode by detecting the operating states of all the exciters and if there is an exciter in the operating state, that is, in the state of outputting mechanical energy.

In addition, the number of the above-mentioned exciters may be one or a plurality of, specifically, when the number of the exciters is a plurality, each of the exciters corresponds to one vibration region, therefore, the screen may be divided into a plurality of vibration regions, and one exciter is correspondingly disposed therein, so that the exciters can control the vibration of the screen region in the vibration region, and by reasonably setting the contact area between the exciters and the screen, so that the contact area is too small relative to the vibration region, the vibration interference between adjacent vibration regions may be avoided or negligible.

The vibration parameters corresponding to each vibration region may be the same or different, but each vibration region corresponds to a vibration threshold, for example, an upper limit of vibration amplitude or an upper limit of vibration frequency, so that the more vibration regions participating in vibration sound production, the higher the highest intensity of the produced sound and the higher the highest frequency in theory.

Detecting the working state of each exciter, finding out the exciter in the running state (namely the state of outputting mechanical energy), taking the vibration area corresponding to the exciter as a screen sounding area, and taking the vibration area corresponding to the exciter in the dormant state as a screen non-vibration area, wherein the area is not used for screen vibration sounding and can be used for displaying content.

And acquiring the vibration parameters of the screen sounding area after determining that the electronic device is in the screen sounding mode. Wherein the vibration parameters include vibration amplitude and vibration frequency.

Specifically, the vibration parameter of the screen sound emission area may be obtained by determining an exciter corresponding to the screen sound emission area, and reading a vibration parameter such as a vibration amplitude or a vibration frequency output by the exciter as the vibration parameter of the screen sound emission area.

In addition, the vibration of the screen sounding area can be detected by arranging a sensor, so that the vibration parameters of the screen sounding area can be acquired.

As an embodiment, a distance sensor is disposed below the screen sound emission area of the screen, and a detection direction of the distance sensor is parallel to a vibration direction of the screen, for example, the vibration direction of the screen sound emission area is perpendicular to the light exit surface of the screen, and the detection direction of the distance sensor is perpendicular to the light exit surface of the screen, so that a maximum displacement and a minimum displacement between the screen sound emission area and the distance sensor can be obtained, and thus, a vibration amplitude of the screen sound emission area can be obtained. Wherein, the distance sensor is a laser displacement sensor or an eddy current displacement sensor and the like.

The distance sensor can be used for acquiring the vibration frequency, and specifically, the variation between the maximum displacement and the minimum displacement of the screen sounding region acquired in the preset time period is acquired, so that the vibration frequency of the screen sounding region in the preset time period can be determined, and the vibration frequency of the screen sounding region can be determined.

The distance sensor is connected with a processor of the electronic device, and the processor can acquire the vibration parameters of the screen sounding area detected by the distance sensor. Thereby further determining whether the vibration parameter of the screen sound emission area satisfies a preset condition.

The preset condition is a condition set by a user according to a requirement, and is used for correcting a vibration parameter of the screen sounding area, specifically, the vibration amplitude is greater than a certain value, or the vibration frequency is less than a certain value.

As an embodiment, the determining whether the vibration parameter of the screen sound emission area satisfies the preset condition is determining whether the vibration amplitude of the screen sound emission area is greater than a preset amplitude, if so, determining that the vibration parameter of the screen sound emission area satisfies the preset condition, and if not, determining that the vibration parameter of the screen sound emission area does not satisfy the preset condition, and at this time, determining that the vibration parameter is the vibration amplitude. The preset amplitude is a maximum amplitude value set by the user, and may be a maximum volume that the user can receive, or a limit amplitude value when the screen sound-emitting area vibrates, and if the limit amplitude value is exceeded, the screen may be damaged, or of course, the preset amplitude value may be a limit value set by the user according to the requirement, and is not limited herein.

As another embodiment, the determining whether the vibration parameter of the screen sound emission area meets the preset condition is performed by determining whether the vibration frequency of the screen sound emission area is greater than a preset frequency, if so, determining that the vibration parameter of the screen sound emission area meets the preset condition, and if not, determining that the vibration parameter of the screen sound emission area does not meet the preset condition, and at this time, determining that the vibration parameter is the vibration frequency. The preset frequency is a maximum frequency value set by the user, which may be a maximum tone that the user can receive, or a limit frequency when the screen sound-emitting area vibrates, and if the limit frequency is exceeded, the screen may be damaged, or of course, the preset frequency may be a limit value set by the user according to the requirement, and is not limited herein.

Because different regional vibration parameters are different, the screen can be damaged due to the fact that the vibration amplitude of some regions is too large or the vibration frequency is too fast, sound distortion can be caused, even some noise is generated, effective information in the sound emitted by the electronic device is reduced, and the noise is increased, therefore, when the vibration amplitude is larger than the preset amplitude or the vibration frequency is larger than the preset frequency, the sound with the overlarge amplitude or frequency can be adjusted through adjustment, and the quality of the sound is improved and the screen is protected.

S302: and if the preset conditions are met, adjusting the vibration parameters of the screen sounding area.

The vibration parameter is an index of the driving signal input to the driving circuit, and can determine an electrical parameter of the driving signal output from the driving circuit, for example, a level, a duty ratio, a frequency, and the like of the driving signal, and therefore, if different vibration parameters are set, a vibration state of a screen of the electronic device is also different, for example, if the vibration parameter of the screen sound emission region is a vibration frequency of 20Hz, theoretically, the vibration frequency of the screen sound emission region when vibrating should also be 20 Hz.

Therefore, after the vibration parameter of the screen sounding area is determined to meet the preset condition, the vibration parameter of the screen sounding area is adjusted so that the vibration parameter of the screen sounding area does not meet the preset condition.

Specifically, when the vibration parameter is a vibration amplitude, if the vibration amplitude is greater than a preset amplitude, the vibration amplitude of the screen sound emission area is reduced, so that the vibration amplitude of the screen sound emission area may be less than or equal to the preset amplitude. Specifically, the manner of reducing the vibration amplitude of the screen sound emission area is as follows: and reducing the level value of the driving signal sent to the exciter corresponding to the screen sounding area. The driving signal is a signal composed of high and low levels sent by the driving circuit, and the exciter is used for outputting mechanical energy according to the driving signal so as to drive the screen to vibrate. If the level value of the driving signal is also high, the amplitude of the screen vibration increases as the power output from the exciter increases, and conversely, the amplitude of the screen vibration decreases as the level value decreases.

Specifically, the level value of the driving signal transmitted to the driver corresponding to the sound emission area of the screen may be reduced by providing a filter circuit for limiting the level of the driving signal, that is, filtering out a signal having a level greater than the maximum amplitude corresponding to the filter circuit, for example, the maximum amplitude corresponding to the filter circuit is 20, and the output level of the driving signal is 30, and then the output level of the driving signal becomes 20 after the filtering processing by the filter circuit.

The filter circuit may be disposed between the driving signal and the exciter, as shown in fig. 4, the processor 102 is respectively connected to the input terminal of the driving circuit 132 and the control terminal of the switching circuit 133, the output terminal of the driving circuit 132 is connected to the input terminal of the switching circuit 133, the first output terminal of the switching circuit 133 is connected to the input terminal of the exciter 131, the second output terminal of the switching circuit 133 is connected to the input terminal of the filter circuit 134, and the output terminal of the filter circuit 134 is connected to the input terminal of the exciter 131.

Specifically, which output terminal is conducted may be determined according to a control signal received by the control terminal of the switch circuit 133, for example, when the control signal received by the control terminal of the switch circuit 133 is at a high level, the input terminal of the switch circuit 133 is conducted with the first output terminal, and when the control signal received by the control terminal of the switch circuit 133 is at a low level, the input terminal of the switch circuit 133 is conducted with the second output terminal. The processor 102 is a processor of the electronic device, and is capable of acquiring a vibration parameter of a screen sounding area and determining whether the vibration parameter satisfies a preset condition.

When the processor 102 determines that the vibration amplitude of the screen sounding region is greater than the preset amplitude, the processor outputs a control signal to the control terminal of the switch circuit 133 to switch on the input terminal and the second output terminal of the switch circuit 133. The processor 102 inputs an audio signal to the driving circuit 132 through an input of the driving circuit 132, the driving circuit 132 outputs a driving signal according to the audio signal, and after being subjected to a filtering process by the filtering circuit 134, the level of the driving signal is lowered and then the filtered driving signal is sent to the exciter.

As another embodiment, when the vibration parameter is a vibration frequency, and the vibration frequency of the screen sound emission area is greater than a preset frequency, the vibration frequency of the screen sound emission area is reduced, specifically, a frequency value of a driving signal sent to an exciter corresponding to the screen sound emission area is reduced, so as to reduce the vibration frequency of the screen sound emission area. The frequency value of the drive signal may be reduced by reducing the frequency of an oscillator of the drive circuit for generating the drive signal, for example, the frequency may be reduced by frequency division, or the frequency may be increased by frequency multiplication. The frequency of the drive signal decreases, which results in a decrease in the frequency of the vibrations of the sound-emanating area of the screen carried by the actuator.

S303: and controlling an exciter corresponding to the screen sounding area according to the adjusted vibration parameters.

The driving circuit of the electronic device adjusts the driving signal according to the set vibration parameter, for example, if the set vibration parameter is a reduced vibration amplitude, the driving circuit reduces the level value of the high level of the driving signal, and if the set vibration parameter is a reduced vibration frequency, the driving circuit reduces the frequency of the driving signal.

The driving circuit sends the driving signal to the exciter, and the exciter controls the vibration component to vibrate according to the adjusted driving signal, so that the vibration frequency, amplitude and other parameters of the vibration component can be adjusted, and the sound characteristic information such as the strength, frequency and the like of the emitted sound can be changed.

In addition, considering that the vibration parameters of a certain vibration area are adjusted to influence the sound emitted by the electronic device as a whole, the vibration parameters of other vibration areas are adjusted according to the adjustment range of the screen sound emission area, specifically, referring to fig. 5, the method is used for ensuring the quality of the sound when the screen is vibrated and emitted, and specifically, the method includes: s501 to S505.

S501: when the electronic device is detected to be in a screen sound production mode, determining whether the vibration parameters of the screen sound production area meet preset conditions.

S502: and if the preset conditions are met, adjusting the vibration parameters of the screen sounding area.

S503: and controlling an exciter corresponding to the screen sounding area according to the adjusted vibration parameters.

S504: and acquiring the adjustment amplitude of the vibration parameters of the screen sounding area.

The method comprises the steps of obtaining vibration parameters of a screen vibration area when the electronic device starts screen vibration sound production operation at this time, then obtaining the adjusted vibration parameters of the screen sound production area, and obtaining the adjustment amplitude of the vibration parameters of the screen sound production area before and after adjustment. For example, when the electronic device starts the screen vibration sound production operation this time, the vibration amplitude of the screen vibration area is a, and the vibration amplitude of the screen sound production area before adjustment is B, the adjustment amplitude is an absolute value of a-B, and is recorded as M.

S505: and adjusting the vibration parameters of the normal area according to the adjustment amplitude.

And the normal area is a vibration area with the vibration parameters not meeting the preset conditions. Specifically, a plurality of vibration areas are arranged on the screen, each vibration area corresponds to one exciter, and the vibration parameters corresponding to each vibration area can be different, namely when the electronic device is in a screen sounding mode, the vibration areas vibrate, and the vibration parameters of each vibration area can be different. As shown in fig. 6, the vibration area is an area indicated by a dotted circle, and an exciter is correspondingly arranged in the vibration area, so that the exciter can control the screen area in the vibration area to vibrate, and moreover, the contact area of the exciter and the screen is reasonably arranged, so that the contact area is too small relative to the vibration area, and thus, no vibration interference exists between adjacent vibration areas or the vibration interference can be ignored.

And detecting the working state of each exciter, finding out the exciter in the state of outputting mechanical energy, taking the vibration area corresponding to the exciter as a screen sounding area, and taking the vibration area corresponding to the exciter in the dormant state as a screen non-vibration area, wherein the area is not used for screen vibration sounding and can be used for displaying content.

When the electronic device is detected to be in a screen sound production mode, determining all current vibration areas used for vibration sound production or in a vibration state to serve as screen sound production areas, and searching the vibration areas with vibration parameters meeting preset conditions to serve as normal areas.

And after the adjustment amplitude is acquired, adjusting the vibration parameters of the normal area according to the adjustment amplitude, so that the part of the sound emitted by the electronic device, such as the reduced volume and the changed frequency, which is lost because the screen sound emitting area in the abnormal state is adjusted, can not be greatly influenced by the sound emitted by the whole electronic device through the adjustment of the normal area.

For example, if the adjustment amplitude is M as described above, then M is averaged over all the normal regions, e.g., the normal region is 5 vibration regions, and the amplitude of each vibration region is increased by M/5.

In addition, in consideration of a situation, a manner of adjusting the vibration parameter of the screen sound emission area in the abnormal state may be to set the vibration parameter to a very small value, for example, the amplitude is zero, so that the screen sound emission area does not vibrate, then, a preset volume emitted when the electronic device starts the screen vibration sound emission operation this time is obtained, the preset volume is a volume preset by the user for the sound emission this time, and a preset vibration parameter is provided corresponding to the preset volume, the preset vibration parameter is used for emitting the preset volume, and the preset vibration parameter includes a preset vibration amplitude, so that the preset vibration is taken as the current vibration amplitude. And adjusting the vibration parameters of the normal area according to the preset volume, and then controlling the exciter according to the adjusted vibration parameters so that the sound emitted by the normal area according to the adjusted vibration parameters is consistent with the sound emitted by the electronic device when the screen vibration sound production operation is started, so that the sound emitted by the whole electronic device is unchanged after the screen sound production area with the vibration parameters meeting the preset conditions is adjusted, namely the requirement of the preset volume is met.

Furthermore, the vibration parameter of the screen sound emission area whose vibration parameter meets the preset condition may be adjusted by setting the vibration parameter to a very small value, for example, setting the amplitude to zero, so that the screen sound emission area does not vibrate, then selecting one vibration area in the current vibration area that does not vibrate, as a backup vibration area, and then obtaining the vibration parameter of the screen vibration area when the electronic device starts the screen vibration sound emission operation this time, and recording the vibration parameter as the initial vibration parameter. And then, controlling the backup vibration area to vibrate according to the initial vibration parameters so that the sound emitted by the whole electronic device is unchanged after the screen sound emission area with the vibration parameters meeting preset conditions is adjusted.

It should be noted that, for the parts not described in detail in the above steps, reference may be made to the foregoing embodiments, and details are not described herein again.

In addition, in consideration of the fact that the vibration amplitude or the vibration frequency of the screen sound emission area is too large, which may be caused by abnormal states of the screen sound emission area, such as abnormal display, screen fragmentation and the like, specifically, referring to fig. 7, there is shown a sound emission control method provided by an embodiment of the present application, which is used for ensuring the quality of sound when the screen is vibrated to emit sound, specifically, the method includes: s701 to S705.

S701: when the electronic device is detected to be in a screen sound production mode, determining whether the vibration parameters of the screen sound production area meet preset conditions.

S702: it is determined whether the screen sound emission area is in an abnormal state.

If the vibration amplitude or the vibration frequency is too large or the vibration process is influenced by external factors, the screen sound production is abnormal, therefore, after the vibration parameters of the screen sound production area meet the preset conditions, whether the screen sound production area is in an abnormal state is determined, if the screen sound production area is in the abnormal state, S703 is executed, namely, the vibration of the screen sound production area is stopped, and if the screen sound production area is not in the abnormal state, S704 is executed, namely, the vibration parameters of the screen sound production area are adjusted.

The abnormal state may include a display abnormal state or a touch abnormal state, or may be a screen fragmentation state, where the screen fragmentation state may include at least one of a touch screen fragmentation or a display panel fragmentation. Here, the abnormal display state refers to abnormal display of the screen, such as darkening or damage of pixels of a displayed image, which is generally caused by aging of the screen or damage due to an external force. The abnormal touch state refers to the damage of the touch function of the screen, that is, the electronic device cannot detect the operation of the user touching the screen, which is caused by the damage, breakage and loss of the touch function of the local area due to the falling.

As an embodiment, when the abnormal state is the display abnormal state, the specific embodiment of detecting whether the screen sound emission area is in the abnormal state is detecting whether the screen sound emission area is in the display abnormal state.

Specifically, a preset image is displayed in the screen sound emission area. As shown in fig. 8, a preset image is displayed in a screen sound emission area, i.e., a circle in the figure. The preset image may be a monochrome image, and may be an image displayed by a gray system, and all the outlines of the image are composed of gray pixels with different shades. The user observes the preset image displayed in the screen sounding area, and if the user can observe the deletion of a certain pixel point or the displayed image is obviously distorted, the user indicates that the screen sounding area is in an abnormal display state. In addition, a plurality of preset images can be displayed in the screen sounding region, and each preset image is different and can be in different color systems, and specifically, the plurality of preset images can be alternately displayed in the screen sounding region.

After a preset image is displayed in a screen sound emission area, inquiry information for inquiring a user whether the display of the preset image is abnormal is displayed on a screen. As shown in fig. 9, a first prompt window in which inquiry information, i.e., "whether or not display is abnormal", is displayed on the screen, and a decision button, i.e., "yes" in fig. 9, is displayed in the first prompt window, while a negative button, i.e., "no" in fig. 9, is displayed.

And if the user clicks the confirmation button, inputting display abnormal information, receiving the display abnormal information input by the user based on the inquiry information by the electronic device, and then judging that the screen sounding area is in an abnormal display state. If the user clicks the negative button, normal display information is input, the electronic device receives normal display information input by the user based on the inquiry information, namely, if the electronic device does not receive abnormal display information input by the user based on the inquiry information, the electronic device determines that the screen sounding region is not in an abnormal display state, namely, in a normal display state.

It should be noted that, the screen sound emission area currently used for vibration sound emission may include a plurality of vibration areas, and a preset image may be displayed in each vibration area, so as to sequentially determine whether each vibration area is in an abnormal display state, so as to find all the vibration areas in the abnormal display state.

As another embodiment, when the abnormal state is the touch abnormal state, the specific embodiment of detecting whether the screen sound emission area is in the abnormal state is to detect whether the screen sound emission area is in the touch abnormal state.

Specifically, touch information is displayed in the screen sound production area to remind a user of touching the screen sound production area. As shown in fig. 10, a second prompt window is displayed in the screen sound emission area, and touch information, i.e., "please touch" in fig. 10, is displayed in the second prompt window, and after acquiring the prompt of the touch information, the user touches the screen sound emission area.

The electronic device judges whether a touch instruction is received within a preset time, wherein the touch instruction is an instruction input by a user through touch on the screen sounding area. The preset time is a time set by the user according to the requirement, and may be a time period, for example, 10 seconds to 20 seconds, or 30 seconds to 60 seconds. Specifically, the time point of displaying the touch information may be taken as a time starting point, and then, it is detected whether a touch instruction input by the user based on the screen sound emission area is received within a preset time, if the touch instruction is received, it is determined that the screen sound emission area is not in the abnormal touch state, which indicates that the touch screen of the screen sound emission area is not damaged and the touch function is normal, and if the touch instruction is not received, it is determined that the screen sound emission area is in the abnormal touch state, which indicates that the user may touch the screen sound emission area, but the touch screen may not detect the touch gesture of the user due to damage or abnormal touch function.

In addition, as shown in fig. 10, a close button is displayed in the second prompt window, and the user can touch the screen sound emission area after clicking the close button, and after detecting a close command input by the user based on the operation of the close button, the electronic device detects whether the touch command input by the user based on the screen sound emission area is received within a preset time, starting from a time point when the close command is received. Therefore, the misjudgment of the touch abnormal state caused by the fact that the user does not touch the sounding area of the screen for a long time after the touch information is displayed can be avoided.

In addition, whether the touch screen of the screen is damaged or not can be detected by arranging a pressure sensor, so that the screen crushing state of the screen can be detected, specifically, the pressure sensor is arranged between the touch screen and the display panel and can be arranged in a vibration area, because the touch screen can bear certain pressure and has certain flexibility, when a user touches the vibration area, a first pressure value can be detected, and when the touch screen is cracked, and the user clicks the touch area, the detected pressure value is a second pressure value, and the second pressure value is larger than the first pressure value.

Therefore, a pressure value which can be detected by the pressure sensor when the user presses the touch screen at the screen generation area is set and recorded as a preset pressure value under the condition that the touch screen is not cracked, the preset pressure value can be a critical value under the condition that the touch screen is not cracked, when the pressure sensor detects that the pressure value which is input when the user presses the touch screen at the screen generation area is larger than the preset pressure value, the touch screen at the screen generation area is determined to be damaged, the screen sound generation area is determined to be in the cracked state of the screen, and the screen sound generation area can also be determined to be in the abnormal touch state.

It should be noted that, it may be determined that the sound emission area of the screen is in the abnormal state as long as one abnormal state occurs in the display abnormal state or the touch abnormal state, or it may be determined that the sound emission area of the screen is in the abnormal state only when it is detected that the sound emission area of the screen is in the display abnormal state or the touch abnormal state.

S703: stopping the vibration of the screen sound emission area.

When the screen sounding area is in an abnormal state, in order to avoid aggravating the damage of the screen due to continuous vibration, the vibration of the screen sounding area is stopped, namely, an exciter corresponding to the screen sounding area is turned off.

S704: and adjusting the vibration parameters of the screen sounding area.

S705: and controlling an exciter corresponding to the screen sounding area according to the adjusted vibration parameters.
