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.

The display screen generally plays a role in an electronic device such as a mobile phone or a tablet computer to display 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.

As the user demands higher definition and higher fineness of the displayed content, more electronic devices employ touch display screens with larger sizes. 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 and 2, an electronic device 100 according to an embodiment of the present application is shown. Fig. 1 is a front view of the electronic device, and fig. 2 is a side view of the electronic device.

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, 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, 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.

In the embodiment of the present application, the vibration component may be the screen 120, and 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 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, i.e., 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 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, the detection circuit is configured to collect environmental noise in a current environment of the electronic device based on the obtained sound emission request, obtain a sound intensity of the environmental noise, and set a vibration parameter of the vibration component according to the sound intensity.

The exciter 131 is connected to a driving circuit of the electronic device, and the driving circuit is configured to input a control signal value according to the vibration parameter to the exciter 131, 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 embodiment of the present application, the plurality of actuators 131 may be uniformly distributed on the screen 120, so that the screen 120 is divided into a plurality of areas for sounding independently. For example, if the number of the actuators is 4, the screen 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 actuators are disposed below the 4 square areas, and the 4 actuators correspond to the 4 square areas one by one. Of course, the number of actuators is not limited in the embodiments of the present application.

In order to solve the technical problem, an embodiment of the present application provides a sound emission control method for reducing an influence of ambient noise on screen sound emission, as shown in fig. 3, specifically, the method includes: s301 to S304.

S301: and acquiring the environmental noise of the electronic device in the current environment based on the acquired sounding request.

The sound production request is information that a user indicates the electronic device and needs to control screen vibration to produce sound. In one embodiment, the sound production request may be a reminder message or a voice playing request.

The reminding information comprises information for reminding a user that some events are triggered, such as call reminding information, short message reminding information, alarm reminding information and the like. For example, the call reminding information is used for reminding the user of a current incoming call, the method of the present application may be executed after the reminding information is acquired and before the sound is not generated, and then the screen is controlled to vibrate and generate the sound after the vibration parameter is acquired, so as to generate a sound for reminding, for example, an incoming call ringtone.

As another embodiment, the utterance request may be a request to play a voice every time the electronic device utters a voice. The method provided by the embodiment of the application is used for collecting the environmental noise to adjust the vibration of the vibration component in the sound production process of the electronic device so as to adjust the sound production.

The electronic device is provided with a sound collection device, which may be a microphone arranged on the electronic device, for collecting the environmental noise under the current environment, i.e. converting the sound signal of the environmental noise into a voice signal. Of course, the sound collection device can also be the vibration part itself, if the vibration part includes casing and screen, then the screen is used for the vibration sound production, thereby controls the vibration by the exciter promptly and makes sound, and the casing can be used to gather surrounding sound, in this application embodiment, make sound and gather sound all can be accomplished by the screen, then when the screen vibration sound production, do not carry out the operation of sound collection, avoid mutual interference.

The vibrating component, e.g. the screen, can pick up sound, similar in principle to a microphone. The material of screen can vibrate, then if the sound wave of current environmental noise arouses when atmospheric pressure changes, the screen can be for the bending along with atmospheric pressure changes, and sets up a backplate in the bottom surface of screen, and this backplate is as a motor of electric capacity, and the screen is as another electrode of electric capacity, because the vibration of screen, can change the electric capacity size between screen and the backplate, just so can convert the change of this electric capacity into the signal of telecommunication to gather sound. As an embodiment, a certain region of the screen may be set to be a screen made of a flexible material, and the thickness of the screen is small enough to be more easily vibrated by the influence of external sound waves.

S302: and acquiring the sound intensity of the environmental noise.

After the environmental noise is collected, the sound characteristics of the environmental noise can be obtained, wherein the sound characteristics comprise the frequency, the sound intensity, the vibration period and other characteristics of the environmental noise and can be obtained through a mathematical model such as spectrum analysis.

S303: and setting vibration parameters of the vibration component according to the sound intensity.

After the sound intensity is obtained, the vibration parameters of the vibration component are adjusted according to the sound intensity, so that a user can hear the sound emitted by the electronic device in the environment noise more easily.

As an embodiment, the specific implementation manner of setting the vibration parameter of the vibration component according to the sound intensity is as follows: and setting the vibration amplitude of the vibration component according to the sound intensity so as to improve the intensity of the sound emitted by the vibration component.

Wherein, the vibration amplitude of vibration part can improve the intensity of the sound that vibration part vibration was sent, the loudness promptly, and improving vibration amplitude can make the sound louder. Therefore, the intensity of the sound emitted by the vibration member can be increased by increasing the vibration amplitude.

Specifically, the current volume of the electronic device is obtained, that is, the volume preset by the electronic device for the sound emission request, for example, if the sound emission request is a call request, the call request corresponds to a preset volume, the preset volume is the volume preset by the user for the call operation, a preset vibration parameter is corresponding to the preset volume, the preset vibration parameter is used for emitting the preset volume, and if the preset vibration parameter includes a preset vibration amplitude, the preset vibration is used as the current vibration amplitude. Of course, if the vibrating component is currently vibrating, the stored vibration parameters in the actuator are directly read to obtain the current vibration amplitude.

Judging whether the sound intensity of the environmental noise is larger than the current volume, if so, increasing the volume of sound emitted by the electronic device, specifically, acquiring a volume difference value between the sound intensity of the environmental noise and the current volume, determining a vibration amplitude to be increased according to the volume difference value, specifically, pre-storing a corresponding relation between the volume and the vibration amplitude in the electronic device, wherein different volumes correspond to different vibration amplitudes, so that the vibration amplitude to be increased corresponding to the volume difference value can be acquired according to the corresponding relation, further, the vibration amplitude to be adjusted is acquired, and then the adjusted vibration amplitude is sent to the exciter so that the exciter controls the vibration of the vibration component according to the adjusted vibration amplitude.

S304: and controlling the vibration component to vibrate according to the set vibration parameters.

The driving circuit of the electronic device adjusts the driving signal according to the set vibration parameter, for example, if the set vibration parameter is the increased vibration amplitude, the driving circuit increases the level value of the high level of the driving signal, and if the set vibration parameter is the increased vibration frequency, the driving circuit increases the frequency of the driving signal.

The driving circuit sends the driving signal to the exciter, and the exciter controls the vibration component to vibrate according to the adjusted driving signal, so that the vibration frequency, amplitude and other parameters of the vibration component can be adjusted, and the sound characteristic information such as the strength, frequency and the like of the emitted sound can be changed.

In addition, when the electronic device is in a call using the headset, it is not necessary to collect environmental noise in the current environment because the vibration part does not need to vibrate when the user uses the headset to receive the voice emitted by the electronic device. Therefore, the embodiment of collecting the environmental noise in the current environment of the electronic device based on the obtained sound emission request includes: determining whether the request to speak corresponds to a non-headset mode of conversation; and if the non-earphone communication mode corresponds to the non-earphone communication mode, acquiring the environmental noise of the electronic device in the current environment. Specifically, referring to fig. 5, the method is used for reducing the influence of ambient noise on screen sounding, and specifically, the method includes: s401 to S405.

S401: determining whether the utterance request corresponds to a non-headset talk mode.

The request to speak may be a request to answer the call at this time.

When the electronic device calls, namely the telephone ring or the vibration reminding rings, the electronic device can detect and display a call interface on a screen. And the user clicks an answering key in the incoming call interface to establish call connection between the current SIM card number of the electronic device and the incoming call number. Specifically, the phone state of the electronic device may be monitored through a phone manager within a system of the electronic device, thereby enabling monitoring whether the electronic device is in a talk mode. The phone manager is an application module in the system of the electronic device, and the user obtains the call status of the electronic device, for example, when the system of the electronic device is an android system, the phone manager is TelephonyManager.

The type of the call mode of the electronic device can be determined by detecting several state values of the electronic device. Specifically, whether the electronic device is connected with the earphone or not is judged, specifically, the judgment can be made by checking the state of the earphone connecting hole of the electronic device, for example, when the earphone connecting hole of the electronic device is connected with the earphone, a first state value is returned, when the earphone in the connecting hole is pulled out, a second state value is returned, and whether the electronic device is connected with the earphone or not can be determined by detecting the first state value and the second state value. Specifically, the android system transmits a broadcast when the headset is plugged in and unplugged, so that the electronic device can determine whether the headset is currently connected to the electronic device by monitoring the broadcast. Thus, it can be determined whether the electronic device is in the headset talk mode.

And the listening to the earpiece mode and the hands-free mode may be determined by listening to a state value of a key for switching between the earpiece mode and the hands-free mode. For example, in the call interface shown in fig. 5, a hands-free button is displayed, the user clicks the hands-free button, the hands-free button is selected, and there is a color change in appearance to indicate to the user that the hands-free button is pressed. The electronic device detects whether the hands-free key is in the selected state, if so, the electronic device is judged to be in the hands-free mode, and if not, the electronic device is judged to be in the receiver mode. It should be noted that the listening to the earpiece mode and the hands-free mode is performed when the electronic device is in the non-earpiece phone call mode.

When the sound production request corresponds to a non-earphone call mode, that is, corresponds to an earphone mode or a hands-free mode, the electronic device may vibrate to produce sound through a vibration component such as a control screen, so that the user can hear the voice, S402 is executed, and if the sound production request corresponds to the earphone call mode, the operation is ended.

S402: environmental noise in a current environment of the electronic device is collected.

S403: and acquiring the sound intensity of the environmental noise.

S404: and setting vibration parameters of the vibration component according to the sound intensity.

S405: and controlling the vibration component to vibrate according to the set vibration parameters.

It should be noted that, for the parts not described in detail in the above steps, reference may be made to the foregoing embodiments, and details are not described herein again.

In addition, considering that the intensity of the environmental noise is high, merely increasing the intensity of the sound emitted by the electronic device may not be enough to enable the user to clearly hear the sound emitted by the electronic device, and thus, the frequency of the sound emitted by the electronic device may be adjusted. Specifically, referring to fig. 6, the method is used for reducing the influence of ambient noise on screen sounding, and specifically, the method includes: s601 to S605.

S601: and acquiring the environmental noise of the electronic device in the current environment based on the acquired sounding request.

S602: and acquiring the sound intensity and the sound frequency of the environmental noise.

After the voice signal of the environmental noise is acquired, the frequency spectrum information of the voice signal is acquired, and the sound intensity and the sound frequency of the environmental noise can be acquired.

S603: setting a vibration amplitude of the vibration member according to the sound intensity.

S604: setting a vibration frequency of the vibration member according to the sound frequency.

After the sound frequency is acquired, a frequency region in which the sound frequency of the environmental noise is mainly distributed can be acquired, and the vibration frequency of the vibration member is set according to the frequency region so that the frequency distribution region of the sound emitted from the vibration member is different from the frequency region in which the sound frequency of the environmental noise is mainly distributed, that is, the frequency distribution region is not completely the same although there is a proper overlap, and there are different regions. For example, if the frequency range in which the sound frequency of the ambient noise is mainly distributed is 800Hz to 1200Hz, and the vibration frequency of the vibration member is set to 600Hz to 900Hz, the frequency of the sound emitted from the vibration member is not overlapped with the frequency of the ambient noise in the 800Hz to 900Hz range, but the frequency of the sound emitted from the vibration member is different from the sound frequency of the ambient noise in the 600Hz to 799Hz range.

S605: and controlling the vibration component to make a sound according to the set vibration frequency and vibration amplitude.

The vibration frequency of the vibration component can be controlled by controlling the vibration of the exciter, specifically, the driving circuit adjusts the frequency of the output driving signal, for example, the driving signal is a square wave signal, the period of the square wave signal can be controlled to control the frequency of the driving signal, the exciter outputs mechanical energy at a high level to drive the screen to vibrate, and the exciter does not vibrate at a low level, therefore, the higher the frequency of the alternating high and low levels, that is, the higher the frequency of the driving signal, the more frequently the exciter drives the screen to vibrate, and the higher the frequency of the sound emitted by the screen vibration is, and vice versa.

In addition, when the frequency distribution of the sound emitted by the electronic device is in the overlapped region with the frequency distribution of the environmental noise, the vibration frequency of the vibration member may be set to have the highest vibration amplitude in the non-overlapped region, so that the sound emitted by the vibration of the vibration member is mainly concentrated in the non-overlapped region, that is, the main lobe of the sound emitted by the vibration is located in the non-overlapped region. For example, the vibration frequency of the above-described vibration member is set to 600Hz to 900Hz, and the frequency region in which the sound frequency of the environmental noise is mainly distributed is 800Hz to 1200Hz, and the sound emitted by the vibration is mainly concentrated between 600Hz to 799 Hz.

Furthermore, the vibration component may be divided into a plurality of regions, and each region corresponds to one exciter, so as to control the vibration sound production of the electronic device more flexibly, for example, the more vibration regions are used for the vibration sound production, the higher the sound volume is, specifically, referring to fig. 7, the method is used for reducing the influence of the environmental noise on the screen sound production, and specifically, the method includes: s701 to S704.

S701: and acquiring the environmental noise of the electronic device in the current environment based on the acquired sounding request.

S702: and acquiring the sound intensity of the environmental noise.

S703: determining a vibration region of the vibration member according to the sound intensity.

In this embodiment of the application, the vibration component is a screen, and the screen is divided into a plurality of vibration regions, as shown in fig. 8, a region shown by a dotted circle is a vibration region, and an exciter is correspondingly arranged in the vibration region, so that the exciter can control the vibration of the screen region in the vibration region, and moreover, by reasonably setting the contact area between the exciter and the screen, the contact area is too small relative to the vibration region, and thus, no vibration interference exists between adjacent vibration regions or the vibration interference can be ignored.

The vibration parameters corresponding to each vibration region may be the same or different, but each vibration region corresponds to a vibration threshold, for example, an upper limit of vibration amplitude or an upper limit of vibration frequency, so that the more vibration regions participating in vibration sound production, the higher the highest intensity of the produced sound and the higher the highest frequency in theory.

As an embodiment, the correspondence relationship between the sound intensity and the vibration area may be stored in the electronic device in advance, specifically, the correspondence relationship between the sound intensity and the vibration area of the environmental noise is stored in the electronic device, one sound intensity corresponds to one or more vibration areas, for example, the intensity a corresponds to the vibration area Q1, and the intensity B corresponds to the vibration areas Q1 and Q2, that is, if the sound intensity of the environmental noise is the intensity a, the vibration area Q1 participates in the vibration sound emission, and if the sound intensity of the environmental noise is the intensity B, the vibration areas Q1 and Q2 participate in the vibration sound emission, the vibration area participating in the vibration sound emission is the vibration area of the installed vibration component. Therefore, according to the corresponding relation between the sound intensity of the environmental noise and the vibration area, the vibration area corresponding to the collected sound intensity of the environmental noise in the current environment of the electronic device can be determined.

As another embodiment, the determining the vibration region of the vibration member according to the sound intensity is performed by:

and judging whether the sound intensity is greater than a preset value. The preset value is a preset sound intensity value, which may be a sound intensity of a sound emitted by the current electronic device, for example, a system volume of the current electronic device or a volume set for an application program corresponding to the sound emission request, or the preset volume. The preset value corresponds to a preset vibration area of the vibration component, and the corresponding preset vibration area is used for sending out volume corresponding to the preset value.

If the sound intensity of the collected environmental noise is larger than a preset value, the preset vibration area is increased, the increased preset vibration area is used as the vibration area for vibration sounding, namely, the vibration area participating in the vibration sounding is increased, so that the sound front degree of the vibration sounding is larger.

For example, the preset vibration regions are vibration regions Q1 and Q2, that is, two vibration regions correspond to each other, and when the sound intensity of the collected ambient noise is greater than the preset value, the preset vibration regions are modified into vibration regions Q1, Q2, and Q3, that is, three vibration regions correspond to each other, and then the vibration regions Q1, Q2, and Q3 are set as the vibration regions at this time.

For another example, the preset vibration regions are vibration regions Q2, Q3, and Q4, that is, corresponding to three vibration regions, when the sound intensity of the collected ambient noise is smaller than the preset value, the preset vibration regions are modified into vibration regions Q2 and Q3, that is, corresponding to two vibration regions, and then the vibration regions Q2 and Q3 are used as the vibration regions set this time.

Therefore, when the sound intensity of the environmental noise is high, the vibration sounding of a large number of vibration areas is controlled, so that the sound volume of the sound generated by the electronic device is increased, and the user can hear the sound generated by the electronic device more clearly. And when the sound intensity of the environmental noise is lower, the vibration area with less vibration is controlled to generate sound, so that the energy consumption of the electronic device can be reduced under the condition that the sound generated by the electronic device can be heard by a user. It should be noted that, when the sound intensity of the collected environmental noise is smaller than the preset value, the preset vibration region may be kept unchanged without changing, or the preset vibration region may be reduced in consideration of the power consumption and the service life of the screen.

In addition, in order to avoid that the vibration region is adjusted too frequently even if the change of the environmental noise is not large after the preset vibration region is adjusted, the electronic device records the sound intensity of the environmental noise collected this time, acquires the change amplitude of the sound intensity of the environmental noise collected last time after the vibration region is adjusted, and does not perform the operation of determining the vibration region of the vibration component according to the sound intensity if the change amplitude is smaller than a preset value. The preset value is set according to requirements and is used for indicating that the change amplitude is small, and the change amplitude can be an absolute value of a difference value of the sound intensity of two times.

S704: and controlling the vibration area of the vibration component to vibrate and sound.

Referring to fig. 9, a sound emission control device 900 provided in an embodiment of the present application is shown, which is used to reduce the influence of ambient noise on the sound emission of a screen, and specifically, the device includes: an acquisition unit 901, an acquisition unit 902, a setting unit 903 and a sound production unit 904.
