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 top 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 100 comprises an electronic body 10, wherein the electronic body 10 comprises a housing 12 and a screen 120 disposed on the housing 12, the housing 12 comprises a front panel 125, a rear cover 127 and a bezel 126, the bezel 126 is used for connecting the front panel 125 and the rear cover 127, and the screen 120 is disposed on the front panel 125.

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 is 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 for detecting whether the screen sound emission area is in an abnormal state, and adjusting the vibration parameter of the screen sound emission area when the screen sound emission area is determined to be in the abnormal state, and a driving circuit. 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.

Through the screen vibration mode, the electronic device can play music outside, and a user can hear the music under the condition that the user is not close to the electronic device. However, the inventor finds in research that, when the electronic device plays music, only one audio is often played, and parameters such as tone and pitch of the music cannot be adjusted, so that the user experience is too low.

Therefore, in order to solve the technical problem, an embodiment of the present application provides a sound emission control method, please refer to fig. 3, which is used for playing multiple audio frequencies when the electronic device vibrates to emit sound. Specifically, the method comprises the following steps: s301 to S304.

S301: a plurality of audio data is acquired.

Specifically, the electronic device may be configured to have audio playing software installed therein, where the audio playing software corresponds to an audio playing interface, and a playlist is displayed in the interface, as shown in fig. 4, names of multiple audios are displayed in the list interface, and each audio name corresponds to one piece of audio data, for example, song 1 corresponding to name 1, and song 2 corresponding to name 2. If the user selects a plurality of audios, and clicks and plays the audios, the electronic device obtains a sound production request, where the sound production request includes a plurality of audio data, such as the audio data corresponding to the selected name 1, name 2, and name 3 in fig. 4.

In the multiple audio data selected under the same interface of the same application shown in figure 4, but may also be audio data under multiple interfaces of the same application program displayed under the split-screen interface, or audio data under respective interfaces of different application programs, as shown in fig. 5, showing one split-screen interface, a first interface and a second interface are included under the split screen interface, as shown in fig. 5, the interface displayed in the upper half area of the screen is the first interface, the interface displayed on the lower half part of the screen is a second interface, illustratively, the first interface and the second interface are both video playing interfaces, and the video played by the first interface is first video data, the first video data corresponds to first audio data, the video played by the second interface is second video data, and the second video data corresponds to second audio data. The first audio data and the second audio data are acquired when the first video data and the second video data are both played.

S302: and determining the vibration frequency corresponding to each piece of audio data, wherein at least two vibration frequencies in the plurality of vibration frequencies are different.

After acquiring a plurality of audio data, configuring a corresponding vibration parameter for each audio data, specifically, the vibration parameter may include a vibration amplitude and a vibration frequency, in this embodiment, if the vibration parameter is a vibration frequency, configuring a vibration frequency for each audio data, and all the vibration frequencies may not be the same, that is, at least two of the audio data have different vibration frequencies.

As an embodiment, the audio data includes first audio data and second audio data, the first audio data corresponds to a first vibration frequency, the second audio data corresponds to a second vibration frequency, and the first vibration frequency is different from the second vibration frequency.

It should be noted that, when configuring the vibration frequency for the first audio data and the second audio data, the first audio data and the second audio data may be subjected to spectrum analysis according to the frequency ranges of the first audio data and the second audio data, so as to obtain the temperament ranges of the first audio data and the first audio data, that is, the first audio data corresponds to a first frequency range and the second audio data corresponds to a second frequency range, where the first frequency range includes a first lowest frequency and a first highest frequency, the second frequency range includes a second lowest frequency and a second highest frequency, and determine whether the first lowest frequency is greater than the second lowest frequency and less than the second highest frequency, if so, it is determined that there is an overlapping region between the first frequency range and the second frequency range, the second vibration frequency may be set, so that the second frequency range of the second audio data is changed into a third frequency range, the third frequency range corresponds to a third lowest frequency and a third highest frequency, and the difference between the third lowest frequency and the third highest frequency is equal to the difference between the second lowest frequency and the second highest frequency, that is, the frequency width of the third frequency range is the same as the frequency width of the second frequency range.

It may be set that the third lowest frequency is greater than the first highest frequency, and of course, it may also be set that an absolute value of a difference between the third lowest frequency and the first lowest frequency is recorded as a first difference, and an absolute value of a difference between the third lowest frequency and the first highest frequency is recorded as a second difference, and then the first difference is greater than the second difference, so that although the first frequency range has an intersection, the intersection between the third frequency range and the first highest frequency range is relatively small, and the listening effect of the second audio data is not too poor due to too high frequency of the third highest frequency.

If the first frequency range does not have any intersection with the second frequency range, the first vibration frequency is set directly from the first frequency range and the second vibration frequency is set directly from the second frequency range without updating for the first vibration frequency or the second vibration frequency. For example, the first frequency range is 300Hz to 500Hz, and the second frequency range is 700Hz to 900Hz, then the first vibration frequency range is 300Hz to 500Hz, and the second vibration frequency range is 700Hz to 900 Hz.

And if the first frequency range is 300Hz to 500Hz and the second frequency range is 350Hz to 900Hz, in one embodiment, the first vibration frequency range is 300Hz to 500Hz and the second vibration frequency range is 450Hz to 1000 Hz.

S303: assigning, by a plurality of the actuators, a target actuator to each of the audio data.

After the vibration frequency corresponding to each audio data is determined, a target exciter may be assigned to each audio data, and specifically, the target exciters assigned to each audio data may be different from each other. For example, taking the first audio data and the second audio data as an example, the first audio data corresponds to the first exciter, and the second audio data corresponds to the second exciter. For example, as shown in fig. 1, the first exciter may be the two exciters at the top in the figure, and the second exciter may be the two exciters at the bottom.

S304: and controlling a target exciter corresponding to the audio data according to the vibration frequency of each piece of audio data so as to drive a vibration area of the screen corresponding to the target exciter to play the corresponding audio data.

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 a reduced vibration amplitude, the driving circuit reduces the level value of the high level of the driving signal, and if the set vibration parameter is a reduced vibration frequency, the driving circuit reduces 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.

The driving circuit is provided with a clock source, such as a crystal oscillator, and an oscillator, wherein the oscillator is capable of setting a vibration frequency, for example, different vibration frequencies are set in a manner of frequency doubling or frequency dividing the vibration frequency of the crystal oscillator, so that a target exciter corresponding to the audio data can be controlled according to the vibration frequency of each audio data.

As an implementation manner, taking an example that the plurality of audio data includes first audio data and second audio data, controlling the first exciter according to the first vibration frequency to drive a first vibration region corresponding to the first exciter to play the first audio data; and controlling the second exciter according to the second vibration frequency so as to drive a second vibration area corresponding to the second exciter to play the second audio data. That is, the first exciter outputs a first vibration frequency and the second exciter outputs a second vibration frequency. In addition, if the first exciter corresponds to a plurality of exciters, the vibration frequencies of the plurality of exciters corresponding to the first exciter are the same, and the vibration frequency of the first exciter is maintained at the first vibration frequency by means of resonance, and the second exciter is the same.

In addition, in order to realize a special effect of singing back of music when the user plays the music, the first audio data and the second audio data may be the same, for example, the first audio data and the second audio data are the same song, and the sampling frequency, the sampling bit number, the bit rate and the corresponding content of the first audio data and the second audio data are the same.

Thus, when a user plays a song, the same song is played in the first vibration region and the second vibration region at different frequencies respectively, and the frequencies represent the tones of the sounds, for example, one tone simulating a male voice and the other simulating a female voice, thereby realizing the effect of male and female duet singing.

In order to realize the effect of synchronous duet singing of two pieces of music, the operation of controlling the first exciter according to the first vibration frequency and the operation of controlling the second exciter according to the second vibration frequency can be controlled to be simultaneously executed, namely, the two pieces of music are played simultaneously and are played in different vibration areas at different frequencies, and the two pieces of music are the same, so that the effect of synchronous duet singing is realized.

In addition, taking the first audio data and the second audio data as an example, it is avoided that the listening effect of the user is affected by mutual interference of two sounds due to too close vibration regions corresponding to the two audio data, as shown in fig. 6, an embodiment of the present application provides a sound emission control method, where the method is used for playing multiple audio frequencies when the electronic device vibrates to emit sound. Specifically, the method comprises the following steps: s601 to S605.

S601: a plurality of audio data is acquired.

S602: and determining the vibration frequency corresponding to each piece of audio data, wherein at least two vibration frequencies in the plurality of vibration frequencies are different.

S603: a first exciter is determined among the exciters corresponding to the top area of the screen, and a second exciter is determined among the exciters corresponding to the bottom area of the screen.

The screen includes top region, middle part region and bottom region, wherein to the screen just to user's angle, be top region, middle part region and bottom region from top to bottom in proper order, then, the top region is close to the camera, and the bottom region is relative with the top region, is close to the home key.

Then, taking an exciter corresponding to the top area of the screen as a first alternative exciter; and taking the exciter corresponding to the bottom area of the screen as a second alternative exciter.

One or more drivers are selected from the first candidate drivers as first drivers and one or more drivers are selected from the second candidate drivers as second drivers, wherein the first drivers may be randomly selected from the first candidate drivers and the second drivers may also be randomly selected from the second candidate drivers, as shown in fig. 7, illustratively, driver J1 and driver J2 are included in top region S1, driver J1 and driver J2 are selected as first candidate drivers, driver J1 is selected from the first candidate drivers as first drivers, driver J3 and driver J4 are included in bottom region S2, driver J3 and driver J4 are selected as second candidate drivers, and driver J3 is selected from the second candidate drivers as second drivers.

As another embodiment, the first exciter and the second exciter may be selected according to the usage record of each exciter, and specifically, the usage record of each of the first candidate exciter and the second candidate exciter corresponding to the preset time period is obtained. Using an exciter, of the first alternative exciters, with a record meeting a first preset standard as a first exciter; and using the exciter which is recorded to meet a second preset standard in the second alternative exciter as the second exciter.

The preset time period is a time period set by a user according to a requirement, for example, within one week or one month. In addition, each exciter in the electronic device has a corresponding identifier, and when the electronic device vibrates to generate sound, the use record of each exciter is recorded, wherein the use record comprises each use time point and each use time length, the use times in the preset time period can be acquired according to each use time point, and the total use time length in the preset time period can be acquired according to each use time length.

Specifically, the first actuator and the second actuator may be determined according to the number of times of use. In one embodiment, the number of times of use of each exciter in a preset time period in the first candidate exciter is obtained, the exciter with the largest number of times of use is used as the exciter with the usage record meeting the first preset standard, and the exciter is used as the first exciter, so that the selected exciter can better conform to the usage habit of the user, and the exciter with the larger number of times of use can be found as the first exciter. Similarly, the second exciter may be selected by using, as the second exciter, the exciter with the largest or smallest number of times of use among the second candidate exciters, which is not described herein again.

As another embodiment, the first and second actuators may be determined according to a total duration of use within a preset time period. Specifically, in the first alternative actuator, the actuator with the largest total duration is selected as the actuator whose usage record satisfies the first preset criterion, and the actuator is thus the first actuator, thereby making it possible to make the selected actuator more suitable for the usage habit of the user, and the actuator with the longest duration of use is found as the first actuator, and of course, the actuator with the smallest total duration may be selected as the actuator whose usage record satisfies the first preset criterion, and the actuator may be thus the first actuator, and thus, the actuator with the shorter total duration of use may be used as the first actuator, thereby avoiding the actuator from being damaged due to overuse. Similarly, the second exciter may be selected by using, as the second exciter, the exciter with the largest or smallest total duration among the second candidate exciters, which is not described herein again.

As still another embodiment, the frequency of use of each exciter may be determined according to the number of uses and the total duration of use, and specifically, the number of uses of each exciter may be divided by the total duration of use to find the frequency of use. Specifically, in the first candidate exciter, the exciter with the largest use frequency is selected as the exciter with the use record meeting the first preset standard, and the exciter is taken as the first exciter, so that the selected exciter can better conform to the use habit of the user, and the exciter with the longest use time length is found as the first exciter. Similarly, the second exciter may be selected by using, as the second exciter, an exciter with the largest or smallest frequency among the second candidate exciters, which is not described herein again.

Thus, the number of uses, the total length of use, or the frequency of use determines the first and second actuators. However, considering that only one dimension is used, a plurality of actuators with the same index may be found, for example, in the case of the first actuator, when the actuator with the largest number of times of use is selected, a plurality of actuators with the same number of times of use may be selected, and if the user only wants to select one actuator as the first actuator, the user needs to filter from a plurality of dimensions.

Specifically, taking the first actuator as an example, one of the three factors, i.e., the number of times of use, the total time of use, or the frequency of use, may be selected as the first factor, the first actuator is determined according to the first factor, and if the first factor determines a plurality of actuators, i.e., the first factor is the number of times of use, and the actuator with the largest or smallest number of times of use is found as a plurality, the user needs to determine one actuator from the plurality of actuators as the first actuator. One element may be selected from the remaining elements excluding the first element from the three elements of the number of uses, the total length of use, or the frequency of use, as the second element, and the third element may be reused if a plurality of exciters remain after the second element is screened.

In one embodiment, taking the first exciter as an example, firstly, the exciter with the largest number of times of use is selected from the first candidate exciters as the first screening exciter, the number of exciters included in the first screening exciter is determined, if the number of exciters is greater than 1, the exciter with the largest total time duration of use is selected from the first screening exciter as the second screening exciter, and if the number of exciters included in the first screening exciter is equal to 1, the first screening exciter is taken as the first exciter.

And if the number of the exciters contained in the second screening exciters is still larger than 1, selecting the exciters with the largest use frequency from the second screening exciters as third screening exciters, and if the number of the exciters contained in the second screening exciters is equal to 1, using the second screening exciters as the first exciters.

If the number of actuators included in the third screening actuator is still greater than 1, the distribution position of each actuator on the screen is determined, the actuator whose distribution position is closest to the frame for the area is selected as the first actuator, and if the number of actuators included in the third screening actuator is equal to 1, the third screening actuator is selected as the first actuator. Taking the first exciter as an example, if the area corresponding to the third screening exciter is the top area, the exciter closest to the top frame is taken as the first exciter, and if the second exciter is the second exciter, the exciter closest to the bottom frame is taken as the first exciter.

S604: and controlling the first exciter according to the first vibration frequency so as to drive a first vibration area corresponding to the first exciter to play the first audio data.

S605: and controlling the second exciter according to the second vibration frequency so as to drive a second vibration area corresponding to the second exciter to play the second audio data.

The execution sequence of S604 and S605 is not sequential, and may be that both are executed synchronously, or S605 is executed first and then S604 is executed.

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.
