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. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Electronic devices often produce sound through speakers, earphones, and the like, which often require openings in the electronic devices. On one hand, the product performance is reduced due to the open pores, and in order to achieve the appearance effect, various manufacturers try to reduce the size of the open pores, but the smaller the open pores are, the more the performance is affected; on the other hand, the screen accounts for the higher full screen user experience better, but because need keep certain panel region for the receiver realizes the vocal function, at the regional trompil of panel, can't realize full screen, influence user experience.

In addition, the display screen generally plays a role in an electronic device such as a mobile phone or a tablet computer to display contents such as 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.

With the increasing requirements of users on the definition and the fineness of displayed contents, more electronic devices adopt touch display screens with larger sizes to achieve the display effect of a full screen. 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 sound emitting devices such as a sound outlet hole of a receiver and a loudspeaker can be omitted.

Referring to fig. 1, an electronic device 100 according to an embodiment of the present disclosure is shown. The electronic device 100 comprises an electronic body 10, wherein the electronic body 10 comprises a housing 12 and a screen 120 arranged on the housing 12. The housing 12 may be made of metal, such as steel or aluminum alloy. As shown in fig. 2, the housing 12 may include a front panel 132, a rear cover 133, and a bezel 134, the bezel 134 being used to connect the front panel 132 and the rear cover 133, the screen 120 being disposed on the front panel. In this embodiment, the screen 120 may include a display screen, which generally includes the display panel 111, and may also include a circuit and the like for responding to a touch operation performed on the display panel 111. The Display panel 111 may be a Liquid Crystal Display (LCD) panel, and in some embodiments, the Display panel 111 is a touch screen 109.

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 and sound, 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, part or all of the screen, part or all of 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. The embodiment of the present application is mainly explained by controlling the screen sound.

In the embodiment of the present application, if the vibration component is the screen 120, 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 and a display screen, the display screen is located below the touch screen, and the piezoelectric driver is attached below the display screen, that is, a surface of the display screen far from the touch screen. 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, wherein the detection circuit is configured to determine whether a soft keyboard pops up in a screen display area when receiving a sound signal, and determine a target sound emission area from a sound emission area of the soft keyboard outside a position of the screen display area if the soft keyboard pops up in the screen display area; the driving circuit is used for driving the target sound production area to produce sound in a vibration mode through the exciter according to the sound signal. The exciter 131 is connected to a driving circuit 135 of the electronic device, and the driving circuit 135 is configured to input a control signal value to the exciter 131 according to the vibration parameter, so as to drive the exciter 131 to vibrate, thereby driving the vibrating component to vibrate. The vibration parameter may be determined by the received sound signal, and specifically may be determined according to a vibration frequency and a vibration amplitude of the sound signal to be sounded.

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 present embodiment, there may be two or more actuators 131. As shown in fig. 1, the plurality of actuators 131 may be uniformly distributed on the screen 120, so that the screen 120 may divide different sound emission areas according to the arrangement of the actuators. Wherein each sound emitting area can be driven to emit sound by one or more than one actuator 131, and different sound emitting areas are driven to emit sound by different actuators. When the same sounding area is driven by a plurality of exciters to sound, the exciters can be uniformly controlled, so that the vibration of one sounding area is consistent under the driving of the exciters, and the sounding is consistent.

For example, the distribution of the drivers and the sound emitting areas may be as shown in fig. 3, and the number of the drivers is 4, then the display screen may include 4 rectangular areas a, b, c, and d, which are equally divided by the center line in the vertical direction and the horizontal direction as shown by the dashed line division in fig. 3, where the 4 drivers are disposed below the 4 rectangular areas, the 4 drivers are in one-to-one correspondence with the 4 rectangular areas, and each rectangular area may be used as one sound emitting area.

As another example, the drivers and the sound emitting areas are distributed as shown in fig. 4, and the display screen includes 6 rectangular areas a1 to a6 as shown by the dashed line divisions in fig. 4, each of which serves as a sound emitting area and is driven by one or more drivers. Of course, the number of the exciters is not limited in the embodiment of the present application, and the specific distribution of the exciters and the specific division of the sound emitting area are not limited in the embodiment of the present application.

When the sound is produced through the screen, the sound can be produced by one sound production area, and a plurality of sound production areas or all the sound production areas. The inventor finds that, because the exciter drives the sound production area of the screen to vibrate and produce sound, if the sound production area is touched by a user, the touch of the user affects the vibration of the screen in the sound production area, and therefore the sound production effect of the sound production area is affected.

In addition, the inventor finds that in the case that a soft keyboard pops up in the display area of the screen, the user needs to touch the soft keyboard to input characters into the text box input area of the electronic device. Therefore, if the soft keyboard pops up in the display area of the screen, the probability that the position of the soft keyboard is touched is high, and if the sounding area at the position of the soft keyboard vibrates to sound, the influence of the touch of the user is easily caused. Therefore, the embodiment of the application provides a screen sounding method, a device, an electronic device and a storage medium, wherein a screen is divided into a plurality of sounding areas, and under the driving of corresponding exciters, a target sounding area is determined from the sounding areas except the position of a soft keyboard for sounding, so that the influence of touch on screen sounding is reduced, and the sounding effect is improved. The screen sounding method, device, electronic device and storage medium provided by the embodiments of the present application will be described with reference to the accompanying drawings and specific embodiments.

Referring to fig. 5, an embodiment of the present application provides a screen sounding method applied to an electronic device. As mentioned above, the electronic device comprises a screen capable of generating sound by vibration and an exciter used for driving the screen to generate sound, wherein the screen comprises a plurality of sound generation areas, and different sound generation areas are driven by different exciters to generate sound. Specifically, as shown in fig. 5, the screen sound generating method may specifically include the following steps:

step S110: and judging whether a soft keyboard pops up in a screen display area or not under the condition of receiving the sound signal.

The soft keyboard is a keyboard simulated by software, which is different from a physical keyboard, and can be displayed in a display area of a screen, as shown in fig. 6 by a soft keyboard K. When the soft keyboard is displayed in the display area of the screen, for example, a keyboard of a third-party input method installed in the electronic device, a keyboard of the electronic device system itself, a numeric input keyboard of a calculator, and the like, characters can be input to the electronic device by clicking on the soft keyboard.

Under the condition that the soft keyboard pops up in the display area, a user usually has an input requirement for inputting information through the soft keyboard, such as texts, pictures and the like, and needs to touch the position where the soft keyboard is located, which may affect the vibration and sound production of the screen, so that when a sound signal is received, whether the soft keyboard pops up in the display area of the screen can be judged.

The electronic device can monitor the popping and closing of the soft keyboard, and therefore whether the soft keyboard pops up or not is judged according to a monitoring result under the condition that the sound signal is received. The monitoring manner of whether the soft keyboard pops up is not limited in the embodiment of the present application, for example, whether the soft keyboard pops up is determined by monitoring the visible area of the window through getviewtreeboserv (). addonglobalsayoutlistener ().

The received sound signal may be a music signal, a video language signal, or a system sound, and the specific received sound signal is not limited in the embodiment of the present application.

Step S120: and if so, determining a target sound production area from a sound production area of the soft keyboard outside the position of the screen display area.

In order to reduce the influence of touch on screen vibration sounding, in the embodiment of the present application, the sound signal may be sounded in response to the sounding area that is touched a few times lower. And the probability of touch of the soft keyboard is higher, so when a sound signal is received, if the soft keyboard pops up, the sound can be emitted through the sound emitting area of the soft keyboard outside the position of the screen display area, and the target sound emitting area is determined from the sound emitting area of the soft keyboard outside the position of the screen display area.

The soft keyboard is in a sound production area outside the position of the screen display area, namely in the screen, the sound production area is not corresponding to the display position of the soft keyboard. For example, as shown in fig. 6, the display positions of the software keyboard K on the screen display area correspond to the sound emission areas A3 and a6, and the target sound emission areas are determined from the sound emission areas a1, a2, a4, and a5 other than the sound emission areas A3 and a 6.

Step S130: and driving the target sound production area to produce sound in a vibration mode through an exciter according to the sound signal.

The target sounding area is driven by the exciter to sound the sound signal, so that the received sound signal is converted into sound to be played.

In the embodiment of the application, the target sound production area is determined from the sound production area of the soft keyboard outside the position of the screen display area, and the received sound signal is produced through the target sound production area. Therefore, the electronic device can sound through the screen without depending on sound production devices such as a loudspeaker, a receiver and the like, so that the electronic device is more in line with the light and thin design direction, the influence of touch control of a user on screen vibration sound production can be reduced under the condition of realizing screen sound production, and the sound production effect is improved.

In the embodiments provided by the present application, a specific determination manner of the target sound-emitting area may also be included. As shown in fig. 7, a screen sound generating method provided by an embodiment of the present application may include:

step S210: a sound signal is received.

Step S220: and judging whether the soft keyboard pops up in the screen display area.

Step S230: and if so, determining a target sound production area from a sound production area of the soft keyboard outside the position of the screen display area.

And receiving the sound signal and judging whether the soft keyboard pops up. If the soft keyboard pops up, the screen can be used

The sound emission area is randomly selected from the plurality of sound emission areas, or all the sound emission areas are selected, or the sound emission area is selected according to a preset sound emission area selection standard to emit sound. And, monitoring whether the soft keyboard pops up in real time or periodically.

If the display area of the screen has the soft keyboard pop-up, the target sound production area can be determined from the sound production area of the soft keyboard outside the position of the display area of the screen. As shown in fig. 8, the specific determination manner may include:

step S231: and determining a sound production area corresponding to the position of the soft keyboard in the screen display area as a keyboard sound production area.

After the soft keyboard is popped up, the position of the soft keyboard in the display area of the screen can be determined, as shown in fig. 6, the position is a position interval, and the specific representation mode is not limited, such as can be represented by a coordinate interval in a screen coordinate system. The display position of the soft keyboard in the screen display area is preset, so that when the soft keyboard is displayed, the area range displayed by the soft keyboard in the display area of the screen can be known.

Optionally, generally, when the electronic device performs horizontal screen display and vertical screen display, the display modes of the soft keyboard are different, and the display positions in the display area are different, for example, fig. 6 shows the display of the soft keyboard K in the vertical screen state and fig. 9 shows the display of the software disk K in the horizontal screen state, the soft keyboard displays in fig. 6 and 9 are only schematic, and the specific display positions and display modes of the soft keyboard are not limited. Therefore, when the position of the display area is determined, the horizontal screen and the vertical screen can be respectively determined according to the current screen. For example, a position relationship correspondence table including a correspondence between a screen state of the electronic apparatus and a position of the software keyboard in the screen may be stored in advance. The screen state includes a horizontal screen state and a vertical screen state, that is, the position relationship correspondence table includes the position of the corresponding soft keyboard in the horizontal screen state and the position of the corresponding soft keyboard in the vertical screen state. Therefore, before the sounding area corresponding to the position of the soft keyboard in the screen display area is determined, the position of the soft keyboard in the screen can be determined according to the position relation correspondence table and the screen state of the electronic device. That is, the position of the soft keyboard can be searched from the position relation corresponding table according to whether the screen of the electronic device is in the landscape screen state or the portrait screen state.

After the position of the soft keyboard in the screen display area is determined, the sound production area corresponding to the position of the soft keyboard in the screen display area can be determined according to the position interval distribution of each sound production area in the screen. For example, the display position of the software keyboard is represented by coordinates, and the position interval of the sounding region is represented by coordinates, so that the sounding region corresponding to the software keyboard can be determined by the corresponding relation of the coordinates. In the embodiment of the application, a sounding area corresponding to the position of the soft keyboard in the display area of the screen is defined as a keyboard sounding area. For example, as shown in fig. 6, when the software keyboard K is within the position range corresponding to the sound emission areas A3 and a6, the sound emission areas A3 and a6 are used as the keyboard sound emission areas.

In the embodiment of the present application, as long as the sound emission area of the soft keyboard is displayed, the sound emission area may be defined as a keyboard sound emission area, such as sound emission areas a2, A3, a5 and a6 in the display mode and the sound emission area dividing mode of the soft keyboard K shown in fig. 10; in the range corresponding to the sounding region, the soft keyboard may be defined as the sounding region of the keyboard only if more than half of the area of the soft keyboard is displayed, as shown in fig. 10, which is the sounding regions A3 and a6 in the soft keyboard K display mode and the sounding region dividing mode. In fig. 6, 9, and 10, the areas divided by the dotted lines indicate the respective sound emission areas.

Step S232: and selecting a sounding area different from the keyboard sounding area from a plurality of sounding areas of the screen as a target sounding area.

A sound emission area different from a keyboard sound emission area is selected as a target sound emission area from among a plurality of sound emission areas included in a screen.

As an embodiment, all the sound emission areas different from the keyboard sound emission area may be selected as the target sound emission area. For example, as shown in fig. 6, the keyboard sound emission areas are sound emission areas A3 and a6, and the sound emission areas a1, a2, a4 and a5 are all selected as target sound emission areas.

In addition, one or more sound emission areas may be selected as the target sound emission area from among sound emission areas different from the keyboard sound emission area. As an embodiment, the selection may be a random selection.

As an embodiment, a sound emission area different from the keyboard sound emission area is selected from the plurality of sound emission areas, and one or more sound emission areas are selected as the target sound emission area.

That is, the distance between the position of the soft keyboard and each of the sound emission areas may be calculated, where the sound emission area where the distance calculation is performed is different from the sound emission area where the soft keyboard is located. After the distance between the soft keyboard and each sounding area is obtained, the distance is compared with a preset threshold value, and the sounding area with the distance reaching the preset threshold value with the soft keyboard is selected from each sounding area to serve as a target sounding area. The specific value of the preset threshold is not limited in the embodiment of the application, and can be determined by testing the sound production effect of each sound production area when the soft keyboard is displayed and touched in advance.

In one embodiment, a sound emission area different from the keyboard sound emission area is selected as the target sound emission area from among the plurality of sound emission areas, and specifically, a sound emission area farthest from the keyboard sound emission area may be selected as the target sound emission area from among the plurality of sound emission areas on the screen.

In this embodiment, the distance between the sound emission areas may be stored in advance, and after the keyboard sound emission areas are determined based on the keyboard position, the sound emission area farthest from the keyboard sound emission area may be selected as the target sound emission area based on the pre-stored distance between the sound emission areas.

In addition, this embodiment may be realized by calculating distances between the keyboard sound emission area and each of the other sound emission areas, and selecting a sound emission area having the farthest distance from the calculated distances as the target sound emission area.

In one embodiment, a sound emission area different from the keyboard sound emission area is selected from the plurality of sound emission areas as the target sound emission area, or a distance between the position of the soft keyboard and each sound emission area is calculated, and a sound emission area farthest from the position of the soft keyboard is selected as the target sound emission area.

As an embodiment, an area correspondence table including correspondence between the sound emission area and another sound emission area may be stored in advance. That is, in the area correspondence table, each of the keyboard sound emission areas corresponds to one or more other sound emission areas. In this embodiment, after the keyboard sound emission area is determined, the sound emission area corresponding to the keyboard sound emission area may be searched from the area correspondence table to be used as the target sound emission area.

In this embodiment of the application, the area mapping table stored in advance may be stored in the electronic apparatus before factory shipment. For each electronic device, the correspondence between the sound emission areas in the area correspondence table stored therein may be obtained according to a preliminary test. That is to say, the soft keyboard can be normally displayed in the display area of the screen, and the touch test can be performed on the soft keyboard. When the soft keyboard is detected to be touched, when the soft keyboard sounds through which sound production area or areas, the vibration influence is the smallest, the sound production effect is the best, and the sound production area with the best sound production effect is used as the sound production area corresponding to the sound production area for displaying the soft keyboard in the area corresponding table.

As an embodiment, in the embodiment of the present application, the area correspondence table stored in advance may also include a correspondence relationship between a position of the software keyboard in the screen display area and the sound emission area. That is to say, when the soft keyboard is displayed in the screen display area in advance, the touch test can be performed on the soft keyboard, and the sound production effect of each sound production area can be tested. In the touch control test process, when the test soft keyboard is displayed at a possible display position, the vibration sounding is minimally influenced and the sounding effect is the best sounding area under the condition of receiving touch control. Then in the established area correspondence table, the position of the soft keyboard in the screen display area corresponds to the corresponding sound production area with the best sound production effect. The testing may be performed at a factory test of the electronic device.

In the using process of the electronic device, after the display position of the soft keyboard in the display area of the screen is determined, the sound production area corresponding to the position of the soft keyboard in the screen display area in the area corresponding table can be searched; and taking the searched sounding area as a target sounding area.

In addition, in the embodiment of the application, if the sound signal is continuously received, whether the soft keyboard is popped up or not can be judged in real time, or whether the soft keyboard is popped up or not can be judged every time the sound signal is received. If the soft keyboard pops up under the condition of receiving the sound signal, determining the target sound production area from the sound production area of the soft keyboard outside the position of the screen display area, which may include: and judging whether the position where the soft keyboard pops up in the screen display area at the previous time is consistent with the position where the soft keyboard pops up in the screen display area at present. If yes, the target sounding area determined once before is used as the current target sounding

An area; if not, determining the target sound production area according to the position of the soft keyboard determined at this time in the screen display area.

Step S240: and driving the target sound production area to produce sound in a vibration mode through an exciter according to the sound signal.

The target sound production area is used as a sound production area for producing sound of the sound signal, so that a good sound production effect is obtained.

In the embodiment of the application, the keyboard sound production area corresponding to the soft keyboard can be determined according to the display position of the soft keyboard in the display area in the screen, and then the sound production area different from the keyboard sound production area is selected from the multiple sound production areas of the screen to be used as the target sound production area. When the electronic device produces sound according to the sound signal, the sound can be produced through the screen, and the electronic device does not depend on a loudspeaker, so that the electronic device conforms to the direction of the thin design. Moreover, sound can be generated through a sound generating area different from the keyboard sound generating area, the touch control influence is reduced, and a good sound generating effect is obtained.

The embodiment of the application further provides a screen sounding device 300 applied to an electronic device. The electronic device comprises a screen capable of vibrating to generate sound and an exciter used for driving the screen to generate sound, wherein the screen comprises a plurality of sound generating areas, and different sound generating areas are driven by different exciters to generate sound. Referring to fig. 11, the screen sound emission device 300 includes: the determining module 310 is configured to determine whether a soft keyboard pops up in the screen display area when the sound signal is received.
