Thus, the following detailed description of the embodiments of the application provided in the accompanying drawings is not intended to limit the scope of the application as claimed, but is merely representative of selected embodiments of the application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

It should be noted that like numerals and letters refer to like items in the following figures, so once an item is defined in one figure, it does not require further definition and explanation in subsequent figures.

Display screens usually play a role in electronic devices such as mobile phones and tablet computers to display content such as text, pictures, icons, or videos. With the development of touch technology, more and more electronic devices set the display screen to be a touch display screen. In the case of setting a touch display screen, when it is detected that the user is dragging on the touch display screen , click, double-click, slide and other touch operations, it can respond to the user's touch operations.

As users have higher and higher requirements for the clarity and fineness of the displayed content, more electronic devices use larger touch display screens. However, in the process of setting up a touch display screen with a larger size, it is found that functional devices such as a front camera, a proximity light sensor, and an earpiece set at the front end of the electronic device will affect the area that the touch display screen can expand to.

Generally, an electronic device includes a front panel, a back cover, and a frame. The front panel includes a top area, a middle screen area and a lower key area. Usually, the upper forehead area is provided with functional devices such as the earpiece sound hole and the 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 buttons. With the development of technology, the lower key area is gradually cancelled, and the physical keys originally set in the lower key area are replaced by virtual keys in the touch screen.

The earpiece sound hole set in the upper forehead area is more important for the function support of the mobile phone, and it is not easy to cancel easily, so it is difficult to expand the displayable area of the touch screen to cover the upper forehead area. After a series of studies, the inventor found that the sound can be produced by controlling the vibration of the screen, frame or back cover of the mobile phone, so that the setting of the earpiece sound hole can be cancelled.

Illustratively, referring to FIGS. 1 and 2 , an electronic device 100 provided by an embodiment of the present application is shown. 1 is a front view of the electronic device, and FIG. 2 is a side view of the electronic device.

The electronic device 100 includes an electronic body portion 10, the electronic body portion 10 includes a casing 12 and a screen 120 disposed on the casing 12, the casing 12 includes a front panel 125, a rear cover 127 and a frame 126, and the frame 126 is used for The front panel 125 and the rear cover 127 are connected, and the screen 120 is disposed on the front panel 125 .

The electronic device further includes an exciter 131, which is used to drive the vibration part of the electronic device to vibrate. Specifically, the vibration part is at least one of the screen 120 or the casing 12 of the electronic device, that is, the vibration part can It is the screen 120 , the casing 12 , or the combination of the screen 120 and the casing 12 . As an embodiment, when the vibration component is the housing 12 , the vibration component may be the back 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. Specifically, the exciter 131 is attached below the screen 120, and the exciter 131 may be a piezoelectric driver or a motor. As an embodiment, the exciter 131 is a piezoelectric driver. The piezoelectric driver transmits its own deformation to the screen 120 through the action of torque, so that the screen 120 vibrates and emits 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 , that is, the side of the display panel 111 away from the touch screen 109 . Piezoelectric drivers include multilayer piezoelectric ceramic sheets. When a multilayer piezoelectric ceramic sheet expands and contracts with sound, it will drive the screen to bend and deform. Repeatedly, the entire screen forms a bending vibration, so that the screen can push the air and generate sound.

As an embodiment, the electronic device 100 includes a driving circuit. The exciter 131 is connected to the drive circuit of the electronic device, and the drive circuit is used to input a control signal value to the exciter 131 according to the vibration parameter to drive the exciter 131 to vibrate, thereby driving the vibrating component to vibrate. Specifically, the driving circuit may be a processor of an electronic device, or may be an integrated circuit capable of generating a driving voltage or current in the electronic device. The drive circuit outputs high and low level drive signals to the exciter 131, and the exciter 131 vibrates according to the drive signal, and the electrical parameters of the drive signals output by the drive circuit are different, which will cause the vibration parameters of the exciter 131 to be different, for example, the drive signal The duty cycle 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 this embodiment of the present application, a plurality of exciters 131 may be evenly distributed on the screen 120, so that the screen 120 is evenly divided into a plurality of areas where sound is produced independently. For example, if the number of exciters is 4, the screen can be divided into 4 square areas along the vertical and horizontal center lines. The 4 exciters are arranged below the 4 square areas, and the 4 The block square areas correspond one-to-one. Of course, the number of exciters is not limited in the embodiments of the present application.

Through the above-mentioned way of screen vibration, the electronic device can play music, and the user can listen to the music without being close to the electronic device. However, the inventor found in research that if the user's finger or other heavy object presses on the screen when the screen vibrates and sounds, it will affect the vibration of the screen and the sound produced by the screen.

Therefore, in order to solve this technical problem, an embodiment of the present application provides a sound production control method, as shown in FIG. 3 , the method is used to generate sound based on the pressure value pressed on the screen when the screen of the electronic device vibrates and emits sound. Adjust the vibration of the screen to improve the sound effect of screen vibration. Specifically, the method includes: S301 to S304.

S301: When the electronic device is in a state of screen vibration and sound, obtain the current sound volume of the electronic device as an initial volume.

Specifically, it can be determined whether the user is currently in a vibration sounding mode by detecting an operation of an application program of the electronic device, wherein the application program can play voice, for example, a music playing software or a calling application. Specifically, the electronic device is in a vibration sounding mode, which may be receiving a sounding request. The sound request is the information that the user instructs the mobile terminal and needs to control the vibration of the screen to sound. As an implementation manner, the voice request may be a reminder message or a voice playback request.

The reminder information includes call reminder information, SMS reminder information, and alarm reminder information, etc., which are used to remind the user that certain events have been triggered. For example, if the call reminder information is used to remind the user that there is an incoming call, it may be that the electronic device enters the vibration sounding mode after obtaining the reminder information and before sounding, that is, it is in a state of waiting for sounding. Then, after the vibration parameters are acquired, at least one of the screen or the back cover is controlled to vibrate and emit sound, so as to emit a sound for reminding, for example, a ringtone for an incoming call.

As another implementation manner, the voice request may be a request to play the voice every time during the process of the mobile terminal voice. Then, the method of the embodiment of the present application is used to collect environmental noise and adjust the vibration of the vibrating component in the process of sounding by the mobile terminal, and then adjust the sounding.

For example, if the user clicks the play button of a video APP, and the electronic device is not currently in the mute state, when it is detected that the play button is triggered, it will enter at least one vibration sounding mode in the screen or the back cover, and play through the vibration of the screen. video voice.

When the electronic device receives an incoming call, that is, when the phone ringing or the vibration reminder rings, the electronic device can detect and display the incoming call interface on the screen. On the other hand, the user clicks the answer button in the incoming call interface, so as to establish a call connection between the current SIM card number of the electronic device and the incoming call number. Specifically, the phone state of the electronic device can be monitored through a phone manager in the system of the electronic device, thereby being able to monitor whether the electronic device is in a call 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 the Android system, the phone manager is the TelephonyManager.

After it is determined that the electronic device is in the screen vibrating and sounding state, the current sound volume of the electronic device is obtained, where the sound volume is the volume of the voice currently output by the electronic device, for example, the call volume, the system volume, or the music volume of a music playing APP, etc. For the acquisition of the current sound volume, you can first determine the currently working exciter, which is driving the screen of the electronic device to vibrate and sound, and determine the current sound volume according to the vibration parameters of the exciter. For example, the vibration parameter is the vibration amplitude , obtain the vibration amplitude of the exciter, and obtain the current sound volume according to the preset correspondence between the vibration amplitude and the sound volume. Of course, the current sound volume of the electronic device may also be acquired according to a program module of an operating system in the electronic device. For example, mAudioManager=(AudioManager), getSystemService(Context.AUDIO_SERVICE).

Specifically, the way to obtain the system volume is:

max=mAudioManager.getStreamMaxVolume(AudioManager.STREAM_SYSTEM); current=mAudioManager.getStreamVolume(AudioManager.STREAM_SYSTEM); Log.d("SYSTEM","max:"+max+"current:"+current).

In this way, it is determined whether the application program currently playing the voice of the electronic device uses the system volume, the call volume or the independent volume, so as to determine the current sound volume. For example, if the system volume is used, it can be obtained by the above method. The sound volume of the application currently playing voice, that is, the current sound volume of the electronic device, is recorded as the initial volume.

S302: Determine initial driving parameters corresponding to the initial volume.

Wherein, the exciter outputs a driving force according to driving parameters, so as to drive the screen to vibrate and emit sound.

A first correspondence is preset in the electronic device, and the first correspondence includes a plurality of correspondences between sound volume and driving parameters, as shown in Table 1 below:

Table 1

According to the above-mentioned corresponding relationship, the initial driving parameters corresponding to the initial volume can be obtained.

Wherein, the exciter outputs a driving force according to the driving parameters, so as to drive the screen to vibrate and sound. Specifically, the unit of the driving parameter is Newton, that is, the dimension of force. As shown in the above table, F1 means that the driving parameter is F1, and the driving force that can be output is F1. The driving force F1 can drive the screen to vibrate, thereby outputting V1 volume in decibels. In addition, the driving force may be a force output by one exciter, or may be a driving force jointly output by a plurality of exciters.

S303: Detect the pressure value received by the screen, and adjust the initial driving parameter according to the pressure value.

Specifically, a detection circuit is provided under the screen, and the detection circuit can detect the pressure value acting on the screen. Specifically, the detection circuit can be a pressure sensor. When a pressure value acting on the screen is detected, it means that there is an object pressure. On the screen, it may affect the vibration of the screen, and then adjust the driving parameters according to the pressure value.

Specifically, the initial driving parameter may be reduced according to the pressure value. The driving parameter indicates the magnitude of the output driving force. The larger the driving parameter, the larger the output driving force, that is, the driving parameter is positively correlated with the driving force. Reducing the driving parameter can reduce the size of the driving force of the exciter acting on the screen, which can reduce the vibration amplitude of the screen, thereby reducing the sound volume of the screen. When the vibration of the screen causes the limiting effect, if the original driving force is continued to drive the screen to vibrate, it may cause a large squeeze between the screen and the external force, which may easily lead to damage to the screen. At this time, reducing the driving parameters can The driving force of the exciter acting on the screen is reduced, and the vibration amplitude of the screen is reduced, thereby reducing the force between the screen and the external force, and protecting the screen.

As another implementation manner, the initial driving parameter may also be increased according to the pressure value. Thus, the driving force of the exciter acting on the screen can be increased. Specifically, when the screen vibrates, if an external force acts on the screen, such as the user's finger pressing on the screen, the pressure of the user's finger pressing the screen and the driving force driving the screen to vibrate will affect each other, as shown in FIG. 4 , Assuming that the user's finger is pressed on the screen, the pressure F1 of the finger is perpendicular to the screen downward, and the driving force F2 acting on the screen by the exciter is perpendicular to the screen upward. Since the direction of the pressure F1 and the driving force F2 is opposite, the pressure F1 will be Affecting the driving force F2 drives the screen to vibrate, resulting in a smaller vibration amplitude of the screen. Therefore, if the driving force F2 is increased, the effect of the pressure F1 can be overcome. If F2 is larger than F1, the actual driving force acting on the screen is F2-F1. When F2 is increased, the actual driving force will increase, and the vibration amplitude will also increase. Elasticity, not rigid objects, can limit the vibration of the screen within a certain area, that is, the surface of the finger can be recessed inward, and the increase of the driving force can be reasonably set to ensure that the vibration amplitude is the same as before the finger presses the screen. The vibration amplitude is the same, that is, after adjusting the driving force, the volume emitted by the screen is the same as the initial volume.

Specifically, considering the relationship between the pressure value acting on the screen and the driving force acting on the screen by the exciter, the specific implementation of increasing the initial driving parameter according to the pressure value is: determining the initial volume The initial driving force corresponding to the corresponding initial driving parameter; obtaining the difference between the initial driving force and the pressure value; and increasing the initial driving parameter according to the difference.

According to the above table 1, the driving parameters corresponding to the initial volume can be obtained, and the driving parameters represent the driving force. For example, the driving parameter F1 indicates that the driving force is F1, and the pressure value acting on the screen can pass through the detection circuit, such as , the pressure sensor detects the pressure value, and then obtains the difference between the initial driving force and the pressure value, which reflects the influence of the pressure on the screen on the driving force output by the actuator. If the difference is eliminated, the influence of external pressure on the vibration of the screen can be eliminated.

Therefore, the driving force corresponding to the initial volume is recorded as the initial driving force, the above difference is summed with the initial driving force, and the sum is regarded as the adjusted driving force, and then the adjusted driving force is obtained according to Table 1 above. Drive parameter, as the adjusted drive parameter.

In addition, when it needs to be explained, in order to avoid the impact on the screen vibration caused by the non-user's pressing or the pressing of heavy objects, it is still necessary to adjust the vibration parameters to cause excessive power consumption or affect the screen vibration effect, etc. When the effect is detected When the pressure value of the screen is used, the specific implementation of adjusting the initial driving parameter according to the pressure value may be: when detecting the pressure value acting on the screen, judging whether the pressure value is at a preset pressure within the range. Specifically, after acquiring the pressure value acting on the screen, it is determined whether the pressure value is within a preset pressure range, where the preset pressure range includes a first critical value and a second critical value, and the pressure value is within the predetermined pressure range. Within the preset pressure range means that the pressure value is greater than or equal to the first threshold value and less than or equal to the second threshold value, and the pressure value within the preset pressure range means that the pressure value acting on the screen can be considered as a user's pressing operation As a result, the pressure value less than the first threshold value is small, and it can be considered that the pressure value is not caused by user operation, and the pressure value greater than the second threshold value is too large, which is not suitable for driving adjustment of the screen. Therefore, if it is within a preset pressure range, the driving parameter is adjusted according to the pressure value.

Furthermore, when the pressure value acting on the screen is detected, the implementation manner of adjusting the driving parameter according to the pressure value may also be:

When the pressure value acting on the screen is detected, the touch area is determined according to the collected pressure value;

Determine whether the screen is in contact with the human ear according to the touch area;

If not, the drive parameter is adjusted according to the pressure value.

Wherein, the specific manner of determining whether the screen is in contact with the human ear according to the touch area is to acquire the outline of the touch area. Specifically, after acquiring all the touch points pressed on the screen, all the touch points are fitted into a continuous curve to obtain a contour line. Determine whether the contour line matches the preset human ear contour line, wherein the preset human ear contour line may be the contour line of most human ears obtained based on big data, or may be the pre-collected user's ear contour line The contour line attached to the screen, so as to obtain the preset human ear contour line. If the outline of the touch area matches the preset outline of the human ear, it means that the screen is in contact with a human ear.

If it is a human ear, it means that the user may be using the private listening mode instead of the public mode, and the operation of adjusting the driving parameter according to the pressure value is not performed.

S304: Control the exciter to drive the screen to vibrate and emit sound according to the adjusted driving parameters.

Specifically, the drive circuit generates a drive signal to the exciter according to the adjusted drive parameters. Specifically, the drive signal can be a drive voltage or current. Different drive voltages or currents make the drive force output by the exciter different, and the drive voltage Or the larger the current is, the larger the driving force output by the exciter is. In order to increase the driving force, the driving signal can be increased, and in order to reduce the driving force, the driving signal can be decreased.

Therefore, by reducing the driving parameters, the vibration amplitude of the screen can be reduced to protect the screen, and by increasing the driving parameters, when the vibration of the screen is suppressed due to the pressure acting on the screen, the screen can be protected. If the vibration amplitude decreases, if the object under pressure acting on the screen is elastic or can be driven by the screen to vibrate, then by increasing the driving force and increasing the vibration of the screen, the object can vibrate with the vibration of the screen, so that the If the screen can further increase the reduced amplitude, the increased driving force can be reasonably set, so that the screen can still maintain the original vibration amplitude and maintain the original volume when the screen is pressed.

However, for some pressure exerted on the screen, since the object applying the pressure cannot elastically deform or the weight is large, increasing the driving force cannot increase the reduced vibration amplitude. In order to overcome this problem, please refer to Figure 5 , the method is used to adjust the vibration of the screen based on the pressure value pressed on the screen when the screen of the electronic device vibrates and sounds, so as to improve the sound effect of the screen vibration. Specifically, the method includes: S501 to S508.

S501: When the electronic device is in a state of screen vibration and sound, obtain the current sound volume of the electronic device as an initial volume.

S502: Determine initial driving parameters corresponding to the initial volume.

S503: When the pressure value received by the screen is detected, adjust the initial driving parameter according to the pressure value.

S504: Control the exciter to drive the screen to vibrate and emit sound according to the adjusted driving parameters.

S505: Acquire the audio signal collected by the audio collector.

After controlling the exciter to drive the screen to vibrate and emit sound according to the adjusted driving parameters, acquire the audio signal collected by the audio collector. Specifically, the exciter may be controlled to drive the screen to vibrate and sound according to the adjusted driving parameters, and a collection instruction may be sent to the audio collector, where the collection instruction may be an interrupt request, and then the audio collector obtains the After collecting the instruction, collect the audio signal in the current environment.

S506: Acquire the volume difference between the volume of the collected audio signal and the initial volume.

After the audio signal collected by the audio collector is acquired, the volume of the audio signal can be determined by calculating the decibel of the audio signal. For the acquisition of the initial volume, reference may be made to the foregoing embodiment. Then take the volume difference between the volume of the collected audio signal and the initial volume. Specifically, if the volume of the collected audio signal is V2 and the initial volume is V1, then the volume difference is the difference between V1-V2 the absolute value of .

S507: Determine whether the volume difference is greater than a preset value.

In the case of increasing the initial driving parameter according to the pressure value, it is determined whether the volume difference is greater than a preset value. The preset value can be set according to the actual usage. If the volume difference is greater than the preset value, it means the difference between the initial volume when the pressure value does not act on the screen and the output volume value after adjusting the drive parameters after the pressure value acts on the screen. If it is larger, it means that the adjustment does not reduce the influence of the pressure value on the screen vibration. For example, the preset value can be a relatively small number, and the range can be 0-10 decibels, for example, it can be 3 decibels. If the volume If the difference is smaller than the preset value, it means that the volume difference is small, that is, after adjusting the driving parameters, the sound emitted by the screen vibration is close to the initial volume. Then, if it is greater than the preset value, it is determined that the preset standard is met, and S508 is executed.

S508: Control the exciter to stop driving the screen to vibrate and sound.

Then, if the volume of the sound produced by the vibration of the driving screen is far from the initial volume after increasing the driving parameters, it means that the initial volume is reduced compared to when the pressure acts on the screen. The increase of the screen vibration does not increase the amplitude of the screen vibration or the amplitude of the increase is low, it may be that the object acting on the screen is heavy or cannot be elastically deformed, that is, the user's finger is not acting on the screen, then this Stop the vibration of the screen at any time, which can protect the screen and avoid damage to the screen due to vibration and external force.

At this time, reminder information may also be issued to remind the user to eliminate the pressure value acting on the screen. Specifically, the reminder information may be a voice prompt, for example, "Please remove the heavy objects on the screen" and the like.

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

Referring to FIG. 6 , the method is used to adjust the vibration of the screen based on the pressure value pressed on the screen when the screen of the electronic device vibrates and sounds, so as to improve the sound effect of the screen vibration. Specifically, the method includes: S601 to S606.

S601: When the electronic device is in the state of screen vibration and sound, obtain the current screen vibration area and the current sound volume of the electronic device as the initial volume.

When it is determined that the screen of the electronic device is vibrating and producing sound, the current screen vibration area is determined. Specifically, the electronic device includes a plurality of exciters, and each exciter corresponds to a different area of the screen, so that each exciter can drive all the exciters. The corresponding area of the screen vibrates and sounds, and different exciters drive different areas. The area of the screen corresponding to each exciter is determined in advance, as shown in Figure 1. In the electronic device shown in Figure 1, set There are 6 exciters, and each exciter corresponds to an area, such as 2 at the top, 2 at the bottom, and 2 at the middle, and are separated from left to right.

Then, by determining the exciter that is currently driving the screen to sound, the area corresponding to the exciter, that is, the screen vibration area, can be determined.

S602: Determine initial driving parameters corresponding to the initial volume.

S603: When detecting the pressure value received by the screen, obtain a touch area corresponding to the pressure value.

The screen includes a touch screen, and a plurality of pressure sensors are distributed on the touch screen, and each pressure sensor corresponds to a position. When the user presses an area of the screen, the pressure sensor in the area can detect the effect. According to the pressure on the screen, the pressure sensor that has detected the pressure can be determined, and the position corresponding to the pressure sensor can be determined, so that the touched touch area can be obtained.

S604: Determine whether the positions of the touch area and the screen vibration area match.

Specifically, it is determined whether there is an intersection between the touch area and the screen vibration area. If so, it means that the area pressed by the user is exactly the area where the screen vibrates, and it is determined that the touch area matches the position of the screen vibration area. Otherwise, Judgment does not match.

Further, the intersecting area between the touch area and the screen vibration area is obtained, specifically, the first area range of the screen vibration area is determined, and the second area range of the touch area is determined, thereby the first area range and the screen vibration area can be determined. The second area is the intersecting area, and then it is determined whether the area of the intersecting area satisfies the preset area size, where the preset area size may be half the area of the first area, and if the area of the intersecting area satisfies the preset area size If the area size is set, it is determined that the touch area matches the position of the screen vibration area, otherwise, it is determined that they do not match.

Therefore, if the area pressed by the user is not the vibration area of the screen, it means that in some embodiments, the influence of the pressure value pressed by the user on the vibration of the screen can be ignored, and S605 does not need to be performed.

In addition, considering that although the touch area and the screen vibration area do not intersect, if the touch area and the screen vibration area are too close, the vibration of the screen may also be disturbed. If there is an intersection between the touch area and the screen vibration area, If there is, it means that the area pressed by the user is the area where the screen vibrates, then it is determined that the touch area matches the position of the screen vibration area, otherwise, the distance between the touch area and the screen vibration area is obtained, then the distance Measured by the number of pixels on the screen, specifically, the first area range and the second area range can be represented by pixels, then the first position marker is determined in the first area, and the pixel coordinates of the position marker are determined. , in the same way, determine the second position marker in the second area, and determine the pixel coordinates of the position marker. As an implementation manner, the first position marker point may be the center point of the first area, and the second position marker point may be the center point of the second area, and of course, may be any point in the area. The distance between the two is determined according to the pixel coordinates of the first position marker and the pixel coordinates of the second position marker.

Then, it is judged whether the distance is smaller than the preset distance value. If it is smaller, it is determined that the position of the touch area and the screen vibration area match, and if it is greater than or equal to, it is determined that the position of the touch area and the screen vibration area do not match. match. The preset distance value may be a preset empirical value, which is used to indicate that when the distance is smaller than the value, the vibration of the screen vibration area will still be affected.

In addition, the specific implementation manner of judging whether the positions of the touch area and the screen vibration area match may also be: directly obtaining the distance between the touch area and the screen vibration area, and judging whether the distance is less than a preset distance value , if it is less than, it is determined that the position of the touch area and the screen vibration area match, if it is greater than or equal to, it is determined that the position of the touch area and the screen vibration area do not match.
