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. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.

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, and the screen 120 being disposed on the front panel, as shown in fig. 2, with the front panel and the rear cover being disposed opposite to each other. 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, may be a frame 134 of the housing, or the like.

The vibration component can comprise a plurality of sounding areas, each sounding area is driven by one or more exciters to sound, and each sounding area is driven by a different exciter to sound.

Taking the screen 120 as an example of the vibration component, 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, where the detection circuit is configured to monitor a current power amount of the electronic device when receiving a sound signal, and determine whether the current power amount is less than or equal to a first preset threshold; drive circuit is used for if current electric quantity is less than or equal to first preset threshold value, according to sound signal, through the exciter drive the regional vibration sound production of the first quantity of vibration part, first quantity is less than the regional quantity of all sound production of vibration part, if current electric quantity is greater than first preset threshold value, according to sound signal, through the exciter drive the regional vibration sound production of the second quantity of vibration part, the second quantity is greater than first quantity and be less than or equal to the regional quantity of all sound production. 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 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 emission areas are distributed as shown in fig. 4, and the display screen includes 7 rectangular areas a1 to a7 as shown by the dashed line partitions in fig. 4, each of which serves as a sound emission 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 when the electronic device generates sound, the more sound generating areas generate sound, the more actuators are needed to drive the sound generating areas, and therefore, more power consumption and more electricity consumption are needed. When the electric quantity of the electronic device is too low, too many sounding areas sound, the electric quantity of the electronic device can be quickened to be exhausted, and the endurance time of the electronic device is reduced.

Therefore, the present invention provides a sound generating method, device, electronic device and computer readable medium, which divides a screen into a plurality of sound generating areas, and generates sound under the driving of corresponding actuators respectively. If the electric quantity is larger than the first preset threshold value, the sounding areas with the second quantity are used for sounding, and if the electric quantity is smaller than or equal to the first threshold value, the sounding areas with the first quantity smaller than the second quantity are used for sounding, so that the battery endurance time of the electronic device is prolonged. The sound generating method, device, electronic device and computer readable medium provided by the embodiments of the present application will be described in detail by specific embodiments with reference to the accompanying drawings.

Referring to fig. 5, an embodiment of the present application provides a sound generating method applied to an electronic device. As described above, the electronic device includes a vibration component capable of generating sound by vibration and an actuator for driving the vibration component to generate sound by vibration, the vibration component is at least one of a screen and a housing of the electronic device, the vibration component includes a plurality of sound generation areas, and each sound generation area is driven by a different actuator to generate sound. Specifically, as shown in fig. 5, the sound generating method may specifically include the following steps:

step S110: and monitoring the current electric quantity of the electronic device under the condition of receiving the sound signal.

And monitoring the electric quantity of the electronic device under the condition of receiving the sound signal, wherein the electric quantity determined by monitoring each time is the current electric quantity at the monitoring moment.

The received sound signal is not limited, and may be a sound signal of music playing, a sound signal of incoming call reminding, a sound signal of video, game, or voice talkback, for example.

The listening may be a continuous listening of the power conservation of the electronic device upon receipt of the sound signal and for the duration of the sound signal. That is, the monitoring of the power of the electronic device may be maintained as long as sound emission through the sound emission area is required. The continuous monitoring may be real-time monitoring or periodic monitoring performed every preset time period.

In the embodiment of the periodic monitoring, if the monitored power amount changes, for example, the power amount changes from seventy percent to sixty-nine percent, the interval time of the next monitoring is a first interval time, the interval time of the next monitoring is a second interval time, the interval time of the next monitoring is a third interval time, and so on until the monitored power amount changes again. The first interval time is greater than the second interval time, which is greater than the third interval time. That is, the listening interval is long when the power change is just monitored, and the listening interval is gradually shortened when the next power change is monitored, so that a more accurate listening result is obtained with a smaller number of listening times.

In this embodiment of the present application, a specific monitoring manner for monitoring the power of the electronic device is not limited, and may include passively receiving the power of the battery and actively monitoring the power of the battery. For example, when the power of the electronic device changes, the system may automatically send a broadcast, for example, the broadcast sent by the Android system is active _ BATTERY _ CHANGED, and a broadcast receiver may receive a message of the change of the broadcasted power. For another example, the class, such as battermanager, actively acquires the power of the electronic device. For another example, for an android system, various information of the battery may be acquired through an adb (android debug bridge) command, such as an adb shell dumpsys battery, so as to obtain the electric quantity of the battery.

Step S120: and judging whether the current electric quantity is less than or equal to a first preset threshold value. If yes, go to step S130; if not, go to step S140.

And judging whether the monitored electric quantity is less than or equal to a first preset threshold value.

As an embodiment, each time the current electric quantity is monitored, the current electric quantity may be determined once.

As an embodiment, when the monitored current electric quantity is greater than the first preset threshold and the difference between the monitored current electric quantity and the first preset threshold is greater than the first preset difference, the monitored electric quantity may be determined once every interval, that is, after determining whether the monitored electric quantity is less than or equal to the first preset threshold once, and after the interval of the monitoring result of the first number of times, determining whether the monitored electric quantity is less than or equal to the first preset threshold again. And under the condition that the monitored current electric quantity is larger than the first preset threshold value and the difference value between the monitored current electric quantity and the first preset threshold value is larger than the second preset difference value, judging the monitored electric quantity for the second time at intervals. Under the condition that the monitored current electric quantity is larger than the first preset threshold value and the difference value between the monitored current electric quantity and the first preset threshold value is larger than the third preset difference value, the monitored electric quantity can be judged once every third time at intervals, and the like. The first preset difference is larger than the second preset difference, the second preset difference is larger than the third preset difference, the first times is larger than the second times, and the second times is larger than the third times. That is, the larger the difference between the monitored electric quantity and the first threshold value is, the more times the interval is, the judgment is made as to whether the electric quantity is smaller than or equal to the first preset threshold value. When the difference between the monitored electric quantity and the first preset threshold is smaller than a certain preset difference, the judgment of whether the monitored electric quantity is smaller than or equal to the first preset threshold can be performed once every time the current electric quantity is monitored.

Step S130: and driving a first number of sound production areas of the vibration component to vibrate and produce sound through an exciter according to the sound signal, wherein the first number is smaller than the number of all the sound production areas of the vibration component.

Step S140: and driving a second number of sound production areas of the vibration part to vibrate and produce sound through the exciter according to the sound signal, wherein the second number is larger than the first number and is smaller than or equal to the number of all the sound production areas.

If the current electric quantity is larger than a first preset threshold value, the sound production areas with the second quantity are used for carrying out vibration sound production, and if the current electric quantity is smaller than or equal to the first preset threshold value, the sound production areas with the first quantity are used for carrying out vibration sound production. Wherein the first number is smaller than the number of all sound emission areas of the vibration member, and the second number is larger than the first number and smaller than or equal to the number of all sound emission areas. Therefore, under the condition that the electric quantity of the electronic device is larger than the first preset threshold value, the second number of sounding areas can be used for sounding, when the electric quantity is monitored to be reduced, and the electric quantity is too low under the condition that the electric quantity is smaller than or equal to the first preset threshold value, the number of sounding areas for sounding is reduced, the number of exciters needing to be controlled is reduced, the power consumption is reduced, the consumption of the electric quantity is reduced, and the duration of the electronic device is prolonged.

The specific numerical value of the first preset threshold is not limited in the embodiment of the application, and may be an electric quantity value corresponding to the electronic device when performing low-power prompt, or an electric quantity value corresponding to a preset time duration such as 1 hour, 1.5 hours, and the like.

The second number is also not limited in the embodiment of the present application, and may be determined according to a preset setting.

As an embodiment, the second number may be the number of all sound emitting areas of the vibration member.

As an embodiment, the second number may be the number of sound emitting areas set according to the type of the sound signal, such as a second number corresponding to a music signal, a second number corresponding to a call voice signal, and so on, so that a suitable second number corresponds to different types of sound signals, and a better sound emitting effect is obtained.

As an embodiment, the second number may be set by a user.

The specific value of the first number is not limited in the embodiment of the present application, and the sound emission area of the first number may be one sound emission area or a plurality of sound emission areas. The first number is smaller than the total number of sound emission areas provided to the vibration member and smaller than the second number.

In this embodiment of the present application, the sound emitting areas may be selected from the sound emitting areas in the screen, or may be selected from the casing, or both the screen and the casing may select the first number of sound emitting areas, and the specific selection manner is not limited in this embodiment of the present application.

Optionally, in this embodiment of the application, the first number of sound emitting areas may be selected from the casing, so that if the user uses the electronic device, the casing emits sound and vibrates, and the influence of the vibration on the screen may be reduced as much as possible.

Optionally, when the sound signal is received, the attitude sensor may determine whether the rear cover of the electronic device faces downward. If the rear cover faces downwards, a first number of sound production areas are selected from the screen to produce sound, and if the screen faces downwards, a first number of sound production areas are selected from the rear cover to produce sound. Therefore, when the electronic device is arranged on objects such as a desktop, the sound production area vibrates and produces sound in the surface which is not contacted with the surface of the object upwards, the vibration of the sound production area is less affected by the outside, and the sound production effect is better. The attitude sensor may be an accelerometer, a gyroscope, or the like, and is not limited in this embodiment, and the detection of the attitude of the electronic device by the attitude sensor is also not limited in this embodiment.

Alternatively, in the case of receiving the sound signal, it may be determined whether the rear cover of the electronic apparatus is shielded, wherein the determination of whether the rear cover is shielded may be determined by a proximity light sensor, a camera, or the like. And selecting a first number of sound production areas from the sound production areas corresponding to the non-blocked side for vibration sound production. If the rear cover is not shielded, selecting a first number of sound production areas from the rear cover as sound production areas for vibration sound production; if the rear cover is shielded, the sound production areas with the first number are selected from the screen and used as sound production areas for vibration sound production. Or judging whether the screen is shielded or not through devices such as a proximity optical sensor and a camera, and if the screen is not shielded, selecting a first number of sounding areas from the screen as sounding areas for vibration sounding; if the screen is shielded, a first number of sound production areas are selected from the rear cover and used as sound production areas for vibration sound production. Or whether the rear cover and the screen are shielded or not is judged through devices such as a proximity optical sensor and a camera, and a first number of sound production areas are selected from sound production areas corresponding to the non-shielded side to produce sound in a vibration mode.

In this embodiment, the sound production is regional through the sound production of casing or screen under the drive of exciter, and, electron device's electric quantity is greater than first threshold value of predetermineeing, can carry out the sound production with second quantity sound production region, if electron device's electric quantity is less than or equal to the second and predetermines the threshold value, then will carry out the quantity in sound production region of sound production and reduce to first quantity, thereby both can avoid the setting of the sound production device that speaker etc. need go out the sound hole, accord with the direction of electron device slimming design, and can be when the electric quantity is lower, save the electric quantity, improve electron device's time of endurance.

In the embodiment of the application, the number of sounding areas for sounding can be reduced step by step according to the electric quantity of the electronic device. Specifically, referring to fig. 6, the method may include:

If the current electric quantity is less than or equal to the first preset threshold, it may be further determined whether the electric quantity is between the first threshold and the second threshold, or is already less than or equal to the second threshold.

Step S250: and driving a first number of sound production areas of the vibration component to vibrate and produce sound through an exciter according to the sound signal, wherein the first number is smaller than the number of all the sound production areas of the vibration component.

If the current electric quantity is greater than the second preset threshold, that is, the current electric quantity is less than or equal to the first preset threshold but is also greater than the second threshold, the electric quantity of the electronic device is low, but a longer service life can be supported, the first number of sound emitting areas in the vibration part can be driven by the exciter to vibrate and emit sound, and of course, the first number is less than the number of all sound emitting areas of the vibration part and is also less than the second number.

Step S260: and driving a third number of sounding areas of the vibration part to vibrate and sound according to the sound signals through the exciter, wherein the third number is smaller than the first number.

Specifically, referring to fig. 7, the method provided in the embodiment of the present application may include:

step S310: and monitoring the current electric quantity of the electronic device under the condition of receiving the sound signal.

In the embodiment of the application, the current power of the electronic device can be monitored,

optionally, in the embodiment of the present application, the charging state of the electronic device may also be monitored, that is, whether the electronic device is being charged or uncharged is monitored.

The monitoring method for the charging state of the electronic device is not limited. For example, by broadcast transmissions from the system, or by actively acquiring the state of charge.

If the battery of the electronic device is being charged when the sound signal is received, the battery life is not worried about, and the sound can be generated in the second number of sound generation areas. If the battery of the electronic device is not in a charging state, whether the electric quantity is less than or equal to a first preset threshold value can be judged.

Step S320: and judging whether the current electric quantity is less than or equal to a first preset threshold value. If yes, go to step S330; if not, go to step S370.

Step S330: and if the current electric quantity is less than or equal to a first preset threshold value, respectively acquiring the distance between each sounding area and the user.

Step S340: and sequencing the sounding areas according to the distance from small to large.

Step S350: and selecting a first number of sounding areas closest to the sequencing result as sounding areas for vibration sounding.

Step S360: and driving a first number of sound production areas of the vibration component to vibrate and produce sound through an exciter according to the sound signal, wherein the first number is smaller than the number of all the sound production areas of the vibration component.

In the case where it is determined that the current amount of electricity is less than or equal to the first preset threshold, sound emission needs to be performed through the first number of sound emission areas, and therefore, the first number of sound emission areas can be selected from among the plurality of sound emission areas of the vibration member.

In the embodiment of the present application, the selection may be performed by selecting the sound emitting area closest to the user. Specifically, the distance between each sound emission area and the user may be obtained first. And sequencing the sounding areas according to the distance from small to large, namely sequencing the sounding areas according to the distance from small to large between the sounding areas and the user. In the sorting result, the sound emitting areas with the closest distance are selected, for example, the sound emitting areas are arranged from top to bottom according to the distance from small to large, and the sound emitting areas with the first number are selected from top to bottom.

The distance between the sounding area and the user can be obtained by detecting the distance between the user and the distance sensor through the distance sensor, and the distance sensor can be an optical displacement sensor, a linear proximity sensor, an ultrasonic displacement sensor, an infrared pulse sensor and the like. In addition, the distance of the user may be detected by another device capable of detecting the distance, such as a camera.

Optionally, when the distance sensor detects the distance, other objects except the user may be detected by mistake, such as a wall surface and a desktop close to the electronic device, and therefore, the distance between the detected object and the human body may be determined by the infrared sensor and the camera.

In the case of obtaining the distance between the distance sensor and the user, the distance between each sound emitting area in the electronic device and the user may be calculated according to the current posture of the electronic device, the position of each sound emitting area in the electronic device, the position of the distance sensor in the electronic device, and the distance between the user and the distance sensor. Specifically, after obtaining the distance between the distance sensor and the user, according to the current posture of the electronic device, such as whether the electronic device is in a landscape screen state or a portrait screen state, whether the screen is facing upwards or towards, and an included angle between the screen and a horizontal plane, by combining the position of the distance sensor in the electronic device and the position of each sound-emitting area in the electronic device, the distance between each sound-emitting area and the user and the distance difference between the distance sensor and the user may be determined, so as to obtain the distance between each sound-emitting area and the user.

For example, as shown in fig. 8, the screen of the electronic device is facing upwards, the angle is a, the distance sensor is located at a position L1, and the dotted line P indicates the position of the user. The sounding region at L2 is located at a position smaller than the distance sensor to the user by x ═ L × cos (pi-a), where L is the distance between the sounding region at L2 and the distance sensor in the electronic device. Then, in the case where it is detected that the distance between the distance sensor and the user is a, the distance between the sound emission area at the position L2 and the user is B — a-x.

Specifically, the number of sound emission areas corresponding to the distance between the user and the distance sensor may be searched from the correspondence table as the first number. That is, when the distance between the distance sensor and the user is obtained, the distance section corresponding to the distance is searched in the correspondence table, and after the distance section is determined, the number corresponding to the distance section is searched from the correspondence table as the first number.

Optionally, in the embodiment of the present application, the manner of selecting the sound emitting area may also be selected according to the posture of the electronic device. Specifically, when the included angle between the screen and the horizontal plane is smaller than 90 degrees, the upward end of the electronic device is usually closer to the user, and a sound production area is selected from the upward end of the electronic device; when the angle between the screen and the horizontal plane is greater than 90 degrees, as shown in fig. 8, the downward end of the electronic device is generally closer to the user, and the sound emitting area is selected from the downward end of the electronic device. In this selection mode, the angle between the screen and the horizontal plane is the angle between the screen and the horizontal plane on the side where the screen is located as shown in fig. 8, rather than the angle between the horizontal plane on the side where the rear cover is located.

Step S370: if the current electric quantity is larger than a first preset threshold value, according to the sound signals, the second number of sound production areas of the vibration parts are driven by the exciter to vibrate and produce sound, and the second number is larger than the first number and smaller than or equal to the number of all the sound production areas.

The step can refer to the similar steps described above, and is not described herein again.

In the embodiment of the application, under the condition that the current electric quantity is smaller than or equal to the first preset threshold value, the sounding areas of the first number close to the user are selected to sound, so that under the condition that the sounding areas are reduced, the sounding areas are close to the user, the loss of sound in the air is small, the sound heard by the user is larger than the sound far away from the user, and the influence of the sounding areas on the user is reduced as much as possible.
