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 the sound outlet hole of the receiver can be eliminated.

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 away 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 used for detecting the touched position of the screen when receiving the sound signal, and determining a target sound production area from the sound production area except the touched position; 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. 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 settings 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.

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 when the sound signal is received, detecting the position of the screen which is touched.

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 not touched. Therefore, when the sound signal is received, the touched position of the screen can be detected, namely, the touched position corresponding to the touch of the user on the screen is detected.

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.

The specific detection mode for detecting the touch position is not limited in the embodiment of the application, and may be determined according to a specific touch sensing implementation mode of a touch screen, for example, an infrared touch screen, and the touch position of the screen is calculated according to shielding of infrared rays by a user when the user touches the screen; when a user touches the capacitive touch screen, a human body and a conductor layer of the touch screen form a coupling capacitor, and the touch position and the like are determined according to the current intensity of electrodes on the four sides of the touch screen flowing to a contact. The obtained touch position can be represented by coordinates and the like, so that the touch position can be accurately positioned.

Step S120: and determining a target sound-emitting area from the sound-emitting areas except the touched position.

Under the condition that the touch position of the user on the screen is obtained, the sounding area outside the touch position can be obtained, and therefore the target sounding area can be determined from the sounding area outside the touch position. Here, the sound emission area other than the touch position, that is, the sound emission area not corresponding to the touch position, for example, as shown in fig. 6, when the touch position K touches the sound emission area a of the screen, the target sound emission area is determined from the sound emission areas b, c, and d other than the sound emission area a.

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 through the sound production area outside the touch position, and the received sound signal is produced through the target sound production area. Therefore, the electronic device can sound through the screen, the electronic device is more in line with the light and thin design direction, the influence of the touch of a user on the screen vibration sound production can be reduced under the condition of realizing the 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. Referring to fig. 7, a method for generating a screen sound according to an embodiment of the present application may include:

step S210: and when the sound signal is received, detecting the position of the screen which is touched.

In the case where the touched position of the screen is detected, the target sound emission area may be determined from sound emission areas other than the touched position. The specific determination manner may be that a sound emission area corresponding to the touch position is determined, and then a sound emission area different from the sound emission area corresponding to the touch position is selected from a plurality of sound emission areas included in the screen as the target sound emission area, as shown in steps S220 and S230 in fig. 7. In particular, the method comprises the following steps of,

step S220: and determining a sound production area corresponding to the touched position as a touch sound production area.

After the touched position on the screen is determined, the position interval distribution of each sounding area on the screen may be determined, for example, the touch position is represented by coordinates, and the position interval of the sounding area is represented by coordinates, so that the sounding area corresponding to the touch position, that is, which sounding area is touched, may be determined by the correspondence of the coordinates. And defining a sound production area corresponding to the touch position as a touch sound production area. For example, as shown in fig. 6, if the touch position K is within the position section range corresponding to the sound emission area a, the sound emission area a is regarded as the touch sound emission area.

Step S230: and selecting a sounding area different from the touch sounding area from the plurality of sounding areas as a target sounding area.

Selecting a sound emission area different from the touch sound emission area as a target sound emission area from a plurality of sound emission areas included in the screen.

As an embodiment, all the sound emission areas different from the touch sound emission area may be selected as the target sound emission area. For example, as shown in fig. 6, if the touch sound emission area is the sound emission area a, the sound emission areas b, c, and d are all selected as the target sound emission areas.

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

In one embodiment, a sound emission area different from the touch 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, according to the position of the screen being touched and the positions of the respective sound emission areas of the screen, the distance between the touch position and the respective sound emission areas can be calculated, where the sound emission area for which the distance calculation is performed is different from the sound emission area where the touch position is located.

For the touch position, the central point of the touch position may be used as a standard point, and for each sound emission area, the central point may also be used as a standard point, for example, the intersection point of diagonal lines of a rectangular sound emission area is used as a standard point. When the distance is calculated, the distance between the standard point of the touch position and the standard point between the sounding areas can be calculated respectively, so that the distance between the touch position and each sounding area is obtained. For example, if the touch position and the position of the sound emission area are represented by coordinates, the distance between each sound emission area and the touch position is calculated by the coordinates of the center point of the sound emission area and the coordinates of the center point of the touch position.

After the distances between the touch position and the sounding areas are obtained, the distances are compared with a preset threshold value, and the sounding area with the distance reaching the preset threshold value from the touch position is selected from the sounding areas to serve as a target sounding area. The specific value of the preset threshold is not limited in the embodiment of the present application, and may be determined in advance according to the test of the sounding effect of the touch position and the sounding area.

As an embodiment, a sound emission area different from the touch 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.

The embodiment may be implemented by storing the distance between the sounding areas in advance, and after determining the touch sounding area corresponding to the touch position according to the touch position, selecting the sounding area farthest from the touch sounding area according to the pre-stored distance between the sounding areas as the target sounding area.

In addition, the embodiment may be implemented such that distances between the touch sound emission area and each of the other sound emission areas are calculated in real time, and a sound emission area with the farthest distance is selected as the target sound emission area from the calculated distances.

In one embodiment, a sound emission area different from the touch 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.

As an embodiment, a preset correspondence table including correspondence between the sound emission area and another sound emission area may be stored in advance. That is, in the preset correspondence table, each of the sounding regions corresponds to one or more other sounding regions, as shown in fig. 8. In this embodiment, after the touch sounding area is determined, the sounding area corresponding to the touch sounding area may be searched from a preset mapping table to serve as the target sounding area. For example, the touch-control sound-emitting area is a sound-emitting area a, and the sound-emitting area corresponding to the touch-control sound-emitting area is d according to the preset mapping table shown in fig. 8.

In this embodiment of the application, the pre-stored preset mapping table may be stored in the electronic device before factory shipment. For each electronic device, the correspondence between the sound emitting areas in the preset correspondence table stored therein may be obtained according to a preliminary test. That is to say, can carry out the touch-control test in each vocal region in proper order, simultaneously, when detecting every vocal region by the touch-control, when through which vocal region or which vocal region, the vibration influence is minimum, and vocal effect is best, then regards as the vocal region that is corresponding by the vocal region correspondence of touch-control in presetting the correspondence table with the vocal region that vocal effect is best.

As an implementation manner, in the embodiment of the present application, the preset correspondence table stored in advance may also include a correspondence between the touch position and the sound emitting area. That is, the touch test is performed on each position of the screen in advance. For each touch position in the touch test process, when the sound is produced through one or more sound production areas, the vibration sound production is minimally affected, and the sound production effect is best. In the established corresponding relation table, each touch position corresponds to the corresponding sound production area with the best sound production effect.

In the actual use process, the screen receives the touch of a user, and after the touch position is determined, the sound production area corresponding to the touch position is selected from the corresponding relation table to serve as the target sound production area.

In the correspondence table, the touch position may be represented by a position interval, such as a coordinate interval, or may be represented by a position point, such as a coordinate point. If the position interval represents the touch position, when the touch is actually received, the touch position with the highest contact ratio in the corresponding relationship table and the actual touch position can be used as the corresponding touch position of the actual touch position in the corresponding relationship table.

If the touch position is represented by the position point in the corresponding relation table, when touch is actually received, determining a center point of the actual touch position and the position point with the minimum distance in the corresponding relation table, and taking the touch position corresponding to the determined position point as the touch position corresponding to the actual touch position in the corresponding relation table.

When the target area is determined according to the actual touch position, the touch position corresponding to the actual touch position can be found from the corresponding relation table, and then the sounding area corresponding to the found touch position is determined as the target sounding area.

As an implementation manner, in the embodiment of the present application, the screen may receive multiple touches, that is, more than one touched position at the same time. Selecting a sounding area different from the touch sounding area from the plurality of sounding areas as a target sounding area, wherein if the number of touched positions is multiple, the center positions of the plurality of touched positions are determined; and selecting a sounding area which is farthest from the central position and is different from the touch sounding area from the plurality of sounding areas as a target sounding area.

The number of the touch positions may be two or more. If the number of the touch positions is two, the central positions of the two touch positions can be the end points of the two touch positions; if there are a plurality of touch positions, the center positions of the plurality of touch positions may be the center points, the centers of gravity, and the like of polygons formed by the plurality of touch positions.

In addition, in the embodiment of the present application, if the sound signal is continuously received, the touched position of the screen can be monitored in real time. If the sound production change of the touched position of the screen is monitored, determining a target sound production area from the sound production area except the touched position according to the latest touch position; if the touched position of the screen is monitored to be changed relative to the unvoiced sound monitored last time, the target sound production area of the current sound production can be directly determined by the coordinates of the target sound production area determined last time.

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 touch sound-emitting area may be determined according to the touched position of the screen, and then a sound-emitting area different from the touch sound-emitting area is selected from the multiple sound-emitting areas of the screen as the target sound-emitting area. When sound is produced according to the sound signal, sound production can be achieved through the screen and is not necessarily dependent on the loudspeaker, moreover, sound production can be achieved through the sound production area different from the touch sound production area, touch influence is reduced, and a good sound production effect is obtained.
