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.

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

As the user demands higher definition and higher fineness of the displayed content, more electronic devices employ a touch display screen with a larger size. 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 arranged 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.

Further, the first actuator 131 is connected to the display screen 120 for driving the display screen 120 to vibrate. Specifically, the first actuator 131 is attached below the display screen 120, and the first actuator 131 may be a piezoelectric driver or a motor. In one embodiment, the first actuator 131 is a piezoelectric actuator. The piezoelectric actuator transmits its own deformation to the display screen 120 by a moment action, so that the display screen 120 vibrates to produce sound. The display 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, a side of the display panel 111 away from the touch screen 109. The piezoelectric driver includes a plurality of piezoelectric ceramic sheets. When the multi-layer piezoelectric ceramic plate expands and contracts, the multi-layer piezoelectric ceramic plate drives the display screen 120 to bend and deform, and the whole display screen 120 forms bending vibration repeatedly, so that the display screen 120 can push air and generate sound.

The second exciter 132 is coupled to the rear cover 127 for vibrating the rear cover 127. Specifically, the second actuator 132 is attached under the back cover 127. Likewise, the second actuator 131 may be a piezoelectric actuator or a motor. When the second actuator 132 is a piezoelectric actuator, the piezoelectric actuator transmits its deformation to the back cover 127 by a moment action, so that the back cover 127 vibrates to generate sound. The piezoelectric driver includes a plurality of piezoelectric ceramic sheets. When the multi-layer piezoelectric ceramic plate generates sound to expand and contract, the multi-layer piezoelectric ceramic plate drives the rear cover 127 to bend and deform, and the whole rear cover 127 repeatedly generates bending vibration, so that the rear cover 127 can push air and generate sound.

As an embodiment, as shown in fig. 4, the electronic device 100 includes a driving circuit 210 and a processor 102, wherein the driving circuit 210 is connected to a plurality of first actuators and a plurality of second actuators. The processor 102 is configured to detect an orientation of a user with respect to the electronic device 100, and when the user is oriented toward the display screen 120, generate a first driving signal to the driving circuit 210, where the driving circuit 210 drives the first actuator to operate based on the first driving signal, so as to make the display screen 120 sound; when the user faces the housing 12, a second driving signal is generated to the driving circuit 210, and the driving circuit 210 drives the second actuator to operate based on the second driving signal, so as to generate the sound from the housing 12.

Specifically, the driving circuit 210 may be the processor 102 of the electronic device 100, or may be an integrated circuit capable of generating a driving voltage or current within the electronic device 100. The driving circuit 210 outputs a driving signal with a high level and a low level to the first exciter 131 and/or the second exciter 132, the first exciter 131 and/or the second exciter 132 vibrates according to the driving signal, and the different electrical parameters of the driving signal output by the driving circuit 210 may cause the different vibration parameters of the first exciter 131 and/or the second exciter 132, for example, the duty ratio of the driving signal corresponds to the vibration frequency of the first exciter 131, the amplitude of the driving signal corresponds to the vibration amplitude of the first exciter 131, and the like.

In the embodiment of the present application, when the number of the first actuators 131 is multiple, the multiple first actuators 131 may be uniformly distributed on the display screen 120, so that the display screen 120 is divided into multiple areas for emitting sound individually. For example, if the number of the first actuators is 4, the display screen 120 may be divided into 4 square areas along the center line in the vertical direction and the center line in the horizontal direction, the 4 first actuators are disposed below the 4 square areas, and the 4 first actuators correspond to the 4 square areas one by one. Similarly, when there are a plurality of second exciters 132, the plurality of second exciters 132 may be uniformly distributed on the back cover 127, so that the back cover 127 is divided into a plurality of areas for emitting sound individually. For example, if the number of the second actuators is 4, the second actuators may be equally divided into 4 square areas along the center lines in the vertical direction and the horizontal direction, the 4 second actuators are disposed below the 4 square areas, and the 4 second actuators correspond to the 4 square areas one by one. Of course, the number of the first actuators and the second actuators is not limited in the embodiment of the present application.

Therefore, the problem that display effects of components and parts such as a receiver arranged in the direction of the display screen can be greatly influenced is solved, the inventor researches for a long time and provides the sound production control method, the sound production control device, the electronic equipment and the storage medium, when the electronic equipment produces sound, the electronic equipment controls the display screen or the shell to produce sound according to the state of the display screen by monitoring the state of the display screen, the influence of the operation of the user on the sound production effect of the electronic equipment is avoided, and the hearing experience of the user is improved. Embodiments in the present application will be described in detail below with reference to the accompanying drawings.

In an embodiment, please refer to fig. 5, and fig. 5 is a flowchart illustrating a sound emission control method according to an embodiment of the present application. According to the sound production control method, the display screen or the shell is controlled to produce sound according to the state of the display screen by monitoring the state of the display screen, and the sound production effect of the electronic equipment is improved. In a specific embodiment, the sound emission control method is applied to the sound emission control device 400 shown in fig. 7 and an electronic apparatus (fig. 1) equipped with the sound emission control device 400. The following will describe a specific process of the embodiment by taking an electronic device as an example, and it is understood that the electronic device applied in the embodiment may be a smart phone, a tablet computer, a wearable electronic device, and the like, which is not limited specifically herein. As will be described in detail with respect to the flow shown in fig. 5, the above-mentioned sound emission control method may specifically include the following steps:

step S110: and monitoring the state of the display screen.

In this application embodiment, electronic equipment can utilize the display screen sound production, also can utilize the casing to carry out the sound production. In the process of using the electronic device by the user, the display screen generally needs to be operated, and when the user operates the display screen, the user can influence the vibration of the screen on the display screen through touch operation, pressing operation and the like, so that the influence is caused on the sound production of the display screen.

When the user does not operate the display screen, the display screen of the electronic device is usually in a screen locking state.

Therefore, in the embodiment of the application, the state of the display screen of the electronic device can be monitored when the electronic device generates sound, so that the display screen is in a screen locking state or an unlocking state. Specifically, the state of the display screen may be monitored through a system background, and of course, the mode of monitoring the state of the display screen is not limited in this embodiment of the application.

Step S120: and when the display screen is in a screen locking state, controlling the first exciter to work so as to drive the display screen to sound.

In this embodiment of the application, when the display screen is in the screen locking state, it indicates that the user does not currently operate on the display screen, and the display screen of the electronic device faces the user, and in order to ensure the sound production effect of the electronic device, the first exciter is controlled to operate to drive the display screen to produce sound.

It can be understood that when a user does not perform operations such as touch control on the display screen, the vibration of the display screen cannot be influenced by using the display screen to produce sound currently, that is, the sound production of the display screen cannot be influenced. Therefore, when the display screen is in a screen locking state, the first exciter is controlled to work to drive the display screen to sound, and the electronic equipment can have a good sound production effect.

Step S130: and when the display screen is in an unlocked state, controlling the second exciter to work so as to drive the shell to sound.

In this application embodiment, when the display screen is in the unlocked state, the user mostly operates on the display screen, if in the unlocked state, the display screen is utilized to generate sound, the operation of the user can affect the vibration of the display screen, and in order to ensure the sound generating effect of the electronic device, the second exciter is controlled to work so as to drive the shell to generate sound.

In the embodiment of the present application, it should be understood that when the state of the display screen changes during the sound production of the electronic device, the sound production by the display screen and the sound production by the housing are switched. For example, when the display screen is changed from the unlocking state to the screen locking state, the second exciter is controlled to work to change into the first exciter, namely, the shell is used for sounding, and the display screen is used for sounding; when the display screen is changed from the screen locking state to the unlocking state, the first exciter is controlled to work to be changed into the second exciter, namely the display screen is switched to be used for sounding by using the shell.

According to the sound production control method provided by the embodiment of the application, the state of the monitoring display screen is utilized, when the display screen is in the screen locking state, the first exciter is controlled to work, the display screen is driven to produce sound, when the display screen is in the unlocking state, the second exciter is controlled to work, and the driving shell is driven to produce sound, so that the sound production of the electronic equipment is not influenced by the operation of a user, and the sound production effect of the electronic equipment is improved.

In an embodiment, please refer to fig. 6, and fig. 6 is a flowchart illustrating a sound emission control method according to an embodiment of the present application. As will be described in detail with respect to the flow shown in fig. 6, the sound emission control method may specifically include the following steps:

step S210: and monitoring the state of the display screen.

Step S220: and when the display screen is in a screen locking state, judging whether the application for controlling the electronic equipment to sound is a call application or a music application.

In the embodiment of the application, when the display screen is in the screen locking state, whether the application which currently controls the electronic device to sound is a call application or a music application can be judged. It can be understood that, when the display screen is in the screen locking state, usually, a user uses the electronic device to play music or receive a call, and the like, and at this time, the side of the display screen of the electronic device faces the user, and the back cover of the housing faces away from the user, and at this time, the effect of generating sound by using the display screen is better. Therefore, when the display screen is locked, whether the application for controlling the electronic equipment to sound is a call application or a music application is further judged so as to determine whether the display screen is utilized to sound.

Step S230: and if the application is a call application or a music application, controlling the first exciter to work so as to drive the display screen to sound.

When it is determined in step S220 that the application currently controlling the electronic device to generate sound is a call application or a music application, it indicates that the electronic device currently faces the user through the display screen, and at this time, the electronic device generates sound through the display screen, and the sound generated through the display screen is transmitted toward the direction of the display screen, so that the sound can be transmitted to the ear of the user better, and therefore, when the display screen is in a screen-locked state, and the application currently controlling the electronic device to generate sound is a call application or a music application, the first exciter is controlled to operate, so as to obtain the sound generated through the display screen.

In addition, in the embodiment of the application, when the display screen is in the screen locking state, if it is determined that the application for controlling the electronic device to sound is not a call application or a music application, it is not necessarily the user facing the display screen at this time, so that the first actuator and/or the second actuator may be controlled to operate to drive the display screen and/or the housing to sound.

In this embodiment, when the number of the first actuators is plural, the plural first actuators may respectively correspond to different regions of the display screen. Step S230 may include:

if the application is a call application, controlling a first exciter corresponding to the upper half area of the display screen to work so as to drive the upper half area of the display screen to sound; and if the music application is carried out, controlling all the first actuators to work so as to drive the whole area of the display screen to sound.

It can be understood that when the application for currently controlling the electronic device to sound is a call application, it indicates that the current user is in a call, and when the call is made, the ear of the user is usually in the upper half area of the display screen, so to ensure the sound production effect of the call, the first actuator corresponding to the upper half area of the display screen can be controlled to operate to drive the upper half area of the display screen to sound. Specifically, the first exciter corresponding to the upper half area is determined, and then the driving signal is sent to the first exciter to drive the upper half area of the display screen to sound. Wherein, when the upper half area of the display screen comprises a first exciter, a driving signal is sent to the first exciter. When the upper half area of the display screen includes a plurality of first actuators, driving signals are transmitted to the plurality of first actuators.

When the application for controlling the electronic equipment to sound is a music application, the electronic equipment plays music currently, and in order to guarantee the music quality, the first exciters in the whole area of the display screen can be controlled to work, namely all the first exciters are controlled to work, and the whole area of the display screen is driven to sound.

In the embodiment of the application, when the application for controlling the electronic device to sound is a conversation application, the positions of the users away from the sound source are different, the sound effect heard by the users is also different, and the influence on the conversation is large. Therefore, when the application for controlling the electronic equipment to sound is a call application and the upper half area of the display screen is used for sound production, the sound production volume can be determined according to the distance for sound production. Therefore, the first exciter corresponding to the upper half area of the display screen is controlled to work so as to drive the upper half area of the display screen to sound, and the method comprises the following steps:

if the application is a call application, detecting distance information of a user relative to a display screen; determining the sound volume of the display screen based on the distance information; and sending a driving signal to a first exciter corresponding to the upper half area of the display screen so as to drive the upper half area of the display screen to sound with the sound volume.

It is understood that the distance information of the user relative to the display screen may be detected first, and specifically, the distance of the user relative to the display screen may be detected by a distance-measuring sensor, and the sensor for detecting the distance of the user relative to the display screen may be a proximity sensor, an ultrasonic sensor, a distance sensor, or the like. Of course, the sensor for detecting the distance of the user with respect to the display screen is not limited in the embodiment of the present application.

And then, according to the distance information of the user relative to the display screen, determining the volume of the sound to be emitted from the upper half area of the display screen. Specifically, the sound volume of the upper half area of the display screen may be determined in such a manner that the distance of the user from the display screen is proportional to the sound volume. It will be appreciated that the further the user is from the display screen, the higher the volume of the sound emitted.

In the embodiment of the application, the electronic device may store a corresponding relationship between a distance of a user relative to the display screen and a sound volume in advance. For example, the relationship between the distance of the user from the display screen and the sound volume may be a linear function, and the sound volume of the display screen is proportional to the distance of the user from the display screen. For example, the correspondence between the distance of the user from the display screen and the sound volume may be stored in the electronic device in the form of a relationship table in which the sound volume corresponding to each distance value is stored.

And finally, after the sound volume is determined, a driving signal can be sent to the first exciter corresponding to the upper half area of the display screen, so that the first exciter corresponding to the upper half area works, and the upper half area of the display screen is driven to sound with the sound volume.

Step S240: and when the display screen is in an unlocked state, detecting whether the display screen is touched.

In this embodiment of the application, when it is monitored in step S210 that the display screen is in the unlocked state, it may be further determined whether the display screen is touched, so as to further determine whether the sound production effect of the electronic device is affected by using the display screen to produce sound at present. Specifically, whether the display screen obtains a touch signal or not can be detected, so as to detect whether the display screen is touched or not.

Step S250: and if the display screen is touched, controlling the second exciter to work so as to drive the shell to sound.

It can be understood that when the display screen is detected to be touched, the display screen is used for sounding at present, and the touch of the user can influence the vibration of the display screen, so that the second exciter can be controlled to work to drive the shell to sound, and the sound production effect of the electronic device cannot be influenced.

In the embodiment of the present application, when the number of the second actuators is plural, the plural second actuators may respectively correspond to different regions of the housing. When the shell is used for generating sound, the touch of the user on the shell can also influence the sound generation effect, so that the area which is not touched of the shell can be used as a sound generation area for generating sound. Accordingly, step S250 may include:

the method comprises the steps that touch is conducted on a display screen, a touched area of a shell is detected, and other areas of the shell except the touched area are used as sounding areas; and controlling the second exciter corresponding to the sounding area to work so as to drive the sounding area to sound.

In this embodiment, a plurality of pressure sensors may be disposed on the housing, the plurality of pressure sensors are respectively disposed in different areas of the housing, and the pressure sensors are configured to detect whether the housing is touched, so that the touched area of the housing can be detected. Of course, the manner of detecting the touched area of the housing is not limited in the embodiment of the present application.

After the touched area of the casing is detected, the other area except the touched area of the casing may be used as a sound emission area, and then a driving signal may be emitted to the second actuator corresponding to the sound emission area to operate the second actuator and drive the sound emission area to emit sound.

In the embodiment of the application, when the display screen is in the unlocked state, but it is detected that the display screen is not touched, the first actuator and/or the second actuator may be controlled to operate to drive the display screen and/or the housing to sound.

It can be understood that when the display screen is not touched, the display screen is used for generating sound, and the sound generating effect is not influenced, so that the first exciter or the second exciter can be controlled to work to drive the display screen or the shell to generate sound, the first exciter and the second exciter can be controlled to work simultaneously, and the display screen and the shell are driven to generate sound simultaneously.

According to the sound production control method provided by the embodiment of the application, when the display screen is in the screen locking state, after the application for controlling the sound production of the electronic equipment is judged to be a call application or a music application, the first exciter is controlled to work to drive the display screen to produce sound, when the display screen is in the unlocking state, whether the display screen is touched or not is judged, and when the display screen is touched, the second exciter is controlled to work to drive the shell to produce sound. Therefore, the sound production of the electronic equipment can not be influenced by the operation of the user, and the sound production effect of the electronic equipment is improved.

In one embodiment, referring to fig. 7, fig. 7 shows a block diagram of a sound control apparatus 400 provided in an embodiment of the present application. This vocal controlling means 400 is applied to electronic equipment, electronic equipment includes display screen, casing, at least one is used for driving the first exciter of display screen vocal and at least one is used for driving the second exciter of casing vocal. As will be explained below with respect to the block diagram shown in fig. 7, the sound emission control device 400 includes: a status monitoring module 410, a first control module 420, and a second control module 430. Wherein, the status monitoring module 410 is configured to monitor a status of the display screen; the first control module 420 is configured to control the first exciter to work when the display screen is in a screen locking state, so as to drive the display screen to sound; the second control module 430 is configured to control the second actuator to work when the display screen is in an unlocked state, so as to drive the housing to sound.
