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 configured to obtain a volume of a currently set sound playing, and determine whether the volume is greater than a preset threshold; if the volume is larger than the preset threshold value, the driving circuit drives the first sound-emitting area to emit sound through the exciter according to the sound signal to be emitted. 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. For example, as shown in fig. 3, if the number of the drivers is 4, the display screen may be divided into 4 rectangular regions a, b, c, and d along the center lines in the vertical direction and the horizontal direction, as shown by the dashed line division in fig. 3, where 4 drivers are disposed below the 4 rectangular regions, and the 4 drivers correspond to the 4 square regions one by one. 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.

The embodiment of the application provides a screen sounding method, a screen sounding device, an electronic device and a storage medium. 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. 4, an embodiment of the present application provides a screen sounding method applied to an electronic device. As previously mentioned, the electronic device includes a screen capable of vibrating sound production and at least two actuators for driving the screen to produce sound. The screen includes a first sound emission area and a second sound emission area, which are driven by different actuators, respectively. Specifically, as shown in fig. 4, the screen sound generating method may specifically include the following steps:

step S110: and acquiring the volume of the currently set sound playing.

In the electronic device, the volume of sound playing can be set by a user, and if the volume of sound playing is not set by the user, the volume of sound playing in the electronic device is set as a default. Accordingly, the volume of the currently set sound playback can be acquired.

Alternatively, in the electronic device, the audio stream may be divided into different audio streams (AudioStream), such as media, call, ring tone, and alarm clock. Different volumes may be set for different audio streams. Therefore, in the embodiment of the present application, the acquired volume may be the volume of the currently activated audio stream, or the volume of a corresponding audio stream of a currently playing sound, such as music being played by music playing software.

Optionally, if the sound signal to be sounded is set from the audio stream of the system, or may be set from the playing software, the obtained volume is the volume determined by the audio stream setting of the system and the software setting.

Step S120: and judging whether the volume is larger than a preset threshold value.

Generally, the playing volume of the sound is different, and the loudness of the played sound is different, for example, the louder the volume is, the bigger the loudness is, and the larger the vibration amplitude is required when the sound is produced by the vibration. When the screen is sounding, if the vibration amplitude is too large, the display effect may be affected to a certain extent.

In the embodiment of the application, whether the set volume is larger than a preset threshold value or not can be judged. The specific value of the preset threshold is not limited in the embodiment of the present application, and may be, for example, an intermediate volume value between the maximum volume and the minimum volume, or a volume value that is a certain percentage of the maximum volume, or a volume value that is played at the volume and has a certain influence on the display effect of the display screen.

Step S130: and if the volume is larger than the preset threshold, driving the first sound-emitting area to emit sound through the exciter according to the sound signal to be emitted.

If the volume is larger than the preset threshold, the screen vibrates greatly during sounding, which may have a certain influence on the display effect. Because in general, the user pays less attention to the display of the screen edge relative to the screen center, when the user needs to make a sound, the user can make a sound through the first sound-making area closer to the screen edge, and the influence of the vibration on the display effect and the user impression is reduced.

The sound signal to be sounded may be any sound signal possible for the electronic device to sound, such as a ring tone, an alarm clock, a music play, a video play, a voice, etc.

Optionally, if the electronic device includes different audio streams, the audio stream corresponding to the sound signal to be sounded is activated, and the acquired volume is the volume of the sound signal to be sounded. For example, when a sound signal to be sounded is ready to be sounded, its corresponding audio stream becomes an activated audio stream, and the sound volume set by the audio stream can be acquired.

In the embodiment of the application, if the acquired sound playing volume is greater than a preset threshold, a sound signal to be sounded is sounded through a first sounding area in a screen. The first sound-emitting area is close to the edge of the screen, and the influence on the display effect is smaller. In addition, the first sound-emitting area is close to the edge of the display screen, so that the arrangement is more stable, and the hardware loss of screen vibration is reduced.

In the embodiment of the application, the specific setting of the sound production area is further included. Referring to fig. 5, an embodiment of the present invention provides a method including:

step S210: and acquiring the volume of the currently set sound playing.

Step S220: judging whether the volume is larger than a preset threshold value, if so, executing step S230; if not, go to step S240.

Step S230: and driving the first sound-emitting area to emit sound through the exciter according to the sound signal to be emitted.

And if the set volume is larger than a preset threshold value, playing the sound signal to be sounded through the first sounding area.

Step S240: and driving the second sounding area to sound through the exciter according to the sound signal to be sounded.

In the embodiment of the present application, the first sound emission area is closer to the edge of the screen than the second sound emission area, and the second sound emission area is closer to the center of the screen than the first sound emission area. When a user watches the screen of the electronic device, the user usually pays more attention to the position close to the middle of the screen, and the consistency of the sounding at the position close to the middle of the screen and the display position of the display content is better, so that the user experience is better. Therefore, if the volume is smaller than or equal to the preset threshold, the screen vibrates to produce sound with small vibration, the display effect is less affected, and the sound signal to be produced can be played through the second sound production area.

In the embodiment of the present application, the first sound emission area is closer to the edge of the screen than the second sound emission area. For example, as shown in fig. 6, the first sounding region 136 may be adjacent to the edge of the screen, and the second sounding region 137 is located at the center of the screen. The edge of the screen adjacent to the first sounding region 136 is not limited in the embodiment of the present application. As shown in fig. 6, the first sounding area 136 may be adjacent to four edges, enclosing the second sounding area 137 therein; the first sound emission area 136 may be adjacent to any one or more edges, as shown in fig. 7, and the first sound emission area 136 is adjacent to both edges of the screen. Of course, in the embodiment of the present application, the first sounding region 136 may also have a certain distance from the edge of the screen, as shown in fig. 8. The size, width, and the like of the first sound emission region 136 are not limited in the embodiment of the present application.

In the embodiment of the present application, the screen may include a plurality of sub-sound emission areas, two sub-sound emission areas may be selected from the sub-sound emission areas to be the first sound emission area 136 and the second sound emission area 137, or a part of the sub-sound emission areas may be the first sound emission area 136 and a part of the sub-sound emission areas may be the second sound emission area 137, the sub-sound emission area as the first sound emission area 136 is different from the sub-sound emission area as the second sound emission area 137, and the sub-sound emission area as the first sound emission area 136 is closer to the edge of the screen than the sub-sound emission area as the second sound emission area 137. For example, as shown in fig. 9, the screen includes sub-sound emission areas a1, a2, A3, a4, B1, B2, and B3, and one or more sub-sound emission areas selected from a1, a2, A3, and a4 may be used as the first sound emission area 136, and one or more sub-sound emission areas selected from B1, B2, and B3 may be used as the second sound emission area 137. In the embodiment of the present application, the number and the positions of the sub sound emission regions are not limited.

Wherein different sub-sound-emitting areas are driven by different drivers to emit sound. Specifically, each sub-sound-emitting area may correspond to one actuator, or each sub-sound-emitting area may be driven by a plurality of actuators to emit sound. If a sub-sound-emitting area is driven to emit sound by a plurality of actuators, the plurality of actuators may be controlled in a unified manner.

Optionally, before step S230, the method may further include: from among the sub-sound emission areas adjacent to the edge of the screen, one or more sub-sound emission areas are selected as the first sound emission area 136. The selection may be stored in the electronic device after being selected in advance, or may be selected before the sound is emitted.

The sub-sound-emitting area adjacent to the edge of the screen may be the sub-sound-emitting area closest to the corresponding edge among all the sub-sound-emitting areas. Specifically, the sound emitting sub-area may be located at the edge of the screen; it may also be a sub-sound-emanating area having a distance to the edge of the screen, but closer to the corresponding screen edge than the other sub-sound-emanating areas.

One sub-sound emission area may be selected as the first sound emission area 136 from among sub-sound emission areas adjacent to the edge of the screen, or a plurality of sub-sound emission areas may be selected as the first sound emission area 136. The number of the specifically selected sub-sound-emitting areas is not limited in the embodiment of the present application, for example, the sub-sound-emitting areas adjacent to the four edges of the screen are selected to form the first sound-emitting area 136 shown in fig. 6; as another example, a sub-sound generation region adjacent to two of the edges is selected to form a first sound generation region 136 as shown in fig. 7; the sub sound emission regions adjacent to the edge of the screen may be irregularly selected to form the first sound emission region 136.

Optionally, in the embodiment of the present application, the first sounding area 136 may be preset, or may be determined according to the current posture of the electronic device. Specifically, whether the electronic device is in the landscape screen state or the portrait screen state at present can be judged according to the posture of the electronic device. The electronic device is in a horizontal screen state or a vertical screen state, and can be obtained through detection of a sensor built in the electronic device, such as an accelerometer, a gyroscope, a gravity sensor and the like.

If the electronic device is in the landscape state, as shown in fig. 10, the user may hold the electronic device in the landscape mode, and normally, the edges of the two sides of the transverse axis of the screen are respectively located at the two sides of the user, which respectively correspond to the left ear direction and the right ear direction of the user, and one or more sub-sound-emitting areas may be selected as the first sound-emitting area 136 from the sub-sound-emitting areas adjacent to the edges of the two sides of the transverse axis of the screen. The first sound emission region 136 is determined from the sub-sound emission regions on both sides of the screen lateral axis L1 as shown in fig. 10, for example.

If the screen is in the portrait screen state, the user may hold the electronic device in the portrait screen, and usually, the edges on the two sides of the longitudinal axis of the screen are respectively located on the two sides of the user, and respectively correspond to the left ear direction and the right ear direction of the user, and one or more sub-sound-emitting areas may be selected as the first sound-emitting area 136 from the sub-sound-emitting areas adjacent to the edges on the two sides of the longitudinal axis of the screen. The first sound emission area 136 is determined from the sub-sound emission areas on both sides of the longitudinal axis L2 of the screen, as shown in fig. 11, for example.

Optionally, before step S240, the method may further include: one or more sub-sound emitting areas are selected from a preset range of the center position of the screen as the second sound emitting area 137. The selection may be stored in the electronic device after being selected in advance, or may be selected before the sound is emitted.

If only one sub-sound-producing area exists in the preset range of the central position of the screen, the sub-sound-producing area is used as the second sound-producing area 137; and if a plurality of sub-sounding areas exist in the preset range of the central position of the screen, selecting from the plurality of sub-sounding areas.

The center position of the screen can be the intersection point position of the transverse axis and the longitudinal axis, and can also be the intersection point position of the diagonal lines of the screen. The size of the range of the preset range is not limited in the embodiment of the present application.

Optionally, in this embodiment of the application, one or more sub-sound-emitting areas adjacent to the first sound-emitting area 136 may be selected from the preset range of the center position of the screen to serve as the second sound-emitting area 137, so that under the condition of volume change, the sound-emitting area is switched between the first sound-emitting area 136 and the second sound-emitting area 137, and the sound-emitting position is changed less.

In the embodiment of the present application, the area where sound is emitted may be determined according to the set volume level. When the volume is greater than the preset threshold, the sound signal to be sounded may be sounded through the first sounding region 136. When the volume is smaller than the preset threshold, the sound signal to be sounded may be sounded through the second sounding region 137. According to the method and the device provided by the embodiment of the application, the screen is used for generating sound, so that the design space is saved, and the electronic device conforms to the direction of thin design. In addition, the screen sound production is realized, and the influence of the sound production on the screen display can be reduced.

The embodiment of the application further provides a screen sounding device 300 applied to an electronic device. As shown in fig. 12, the electronic device includes a screen capable of vibrating to generate sound and a plurality of drivers for driving the screen to generate sound, the screen includes a first sound generation area 136 and a second sound generation area 137, the first sound generation area 136 is closer to the edge of the screen than the second sound generation area 137, and the first sound generation area 136 and the second sound generation area 137 are driven to generate sound by different drivers respectively. The screen sound emission device 300 includes: a volume obtaining module 310, configured to obtain a currently set volume of sound playing. The determining module 320 is configured to determine whether the volume is greater than a preset threshold. The playing module 330 is configured to drive the first sounding area 136 to sound through the exciter according to a sound signal to be sounded if the volume is greater than the preset threshold.

Optionally, the playing module 330 may be further configured to drive the second sounding area 137 to sound through the exciter according to the sound signal to be sounded if the volume is less than or equal to the preset threshold.

Optionally, the sound-emitting area determining module may be further configured to select one or more sub-sound-emitting areas as the first sound-emitting area 136 from the sub-sound-emitting areas adjacent to the edge of the screen.

Optionally, in this embodiment of the application, a gesture determining module may be further included, configured to determine, according to the gesture of the electronic device, whether the electronic device is in a landscape state or a portrait state at present. The sound emission area determination module may be further configured to, if the electronic device is in a landscape state, select one or more sub sound emission areas as the first sound emission area 136 from sub sound emission areas adjacent to edges of both sides of a horizontal axis of the screen; if the electronic device is in a vertical screen state, one or more sub sound emission regions are selected as the first sound emission region 136 from the sub sound emission regions adjacent to the edges of the two sides of the longitudinal axis of the screen.
