Detailed Description

Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. The electronic device 20 may be a smart phone, a tablet computer, a Personal Digital Assistant (PDA), or the like.

Among other things, the electronic device 20 may include a plurality of piezoelectric ceramic single bodies such as the piezoelectric ceramic single body 200, the piezoelectric ceramic single body 200 being made of a ceramic material. Piezoelectric ceramic monomer 200 can be with mechanical energy and electric energy interconversion, when piezoelectric ceramic monomer 200 converts the electric energy into mechanical energy, piezoelectric ceramic monomer 200 can drive other deformable's object and produce deformation, make other object vibrations sound, for example can drive the display screen such as display screen 600 vibration, make the air around the display screen 600 flow, thereby make sound, display screen 600 can directly be regarded as electronic equipment's speaker this moment, need not to set up the speaker in electronic equipment 20 inside additionally, also can need not to set up out the sound hole on electronic equipment 20.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a piezoelectric ceramic single body in the electronic device shown in fig. 1. The shape of the piezoelectric ceramic single body 200 may be a regular shape, for example, the piezoelectric ceramic single body 200 may have a rectangular structure, a rounded rectangular structure, a circular structure, or the like. The piezoelectric ceramic monolith 200 may have an irregular shape.

the single piezoelectric ceramic body 200 may include a first piezoelectric ceramic sheet 210, a diaphragm 220, and a second piezoelectric ceramic sheet 230, which are stacked. The first piezoceramic sheet 210 and the second piezoceramic sheet 230 are conductors and may be used to conduct current. Diaphragm 220 is a non-conductor and may not be used to conduct current.

the size of the diaphragm 220 is larger than the size of the first piezoceramic sheet 210 and the second piezoceramic sheet 230. The diaphragm 220 may include a first region and a second region, the second region being disposed at a periphery of the first region. For example, the second region may be disposed around the periphery of the first region. Wherein the first piezoceramic sheet 210 and the second piezoceramic sheet 230 are arranged in the first zone such that the second zone is exposed.

The first piezoelectric ceramic plate 210 and the second piezoelectric ceramic plate are respectively electrically connected to an ac power source such as the ac power source 400, so as to convert the electric energy output by the ac power source 400 into mechanical energy. The ac power source 400 is used to output an ac voltage, and the ac power source 400 may include a first electrode 410 and a second electrode 420 having different potential values.

The first piezoceramic wafer 210 has a first end face and a second end face opposite to the first end face, wherein the first end face is a face away from the diaphragm 220, and the second end face is a face connected to the first region. The first end face is electrically connected to the first electrode 410 of the ac power source 400, and the second end face is electrically connected to the second electrode 420 of the ac power source 400.

the second piezoceramic sheet 230 has a third end face and a fourth end face opposite to the third end face, wherein the third end face is connected to the first region, and the fourth end face is away from the diaphragm 220. The third end surface is electrically connected to the second electrode 420 of the ac power supply 400, and the fourth end surface is electrically connected to the first electrode 420 of the ac power supply 400.

As shown in fig. 3 and 4, fig. 3 is a schematic structural view of the piezoelectric ceramic single body shown in fig. 2 in a first bending state, and fig. 4 is a schematic structural view of the piezoelectric ceramic single body shown in fig. 2 in a second bending state.

the alternating voltage direction of the alternating current power source 400 may change with time along with the direction, and the piezoelectric ceramic single body 200 may perform a deformation motion along with the alternating voltage direction.

for example, as shown in fig. 3, when the alternating voltage direction of the ac power supply 400 is output from the first electrode 410 and returns to the second electrode 420, at this time, under the action of the electric field, the first piezoelectric ceramic piece 210 and the second piezoelectric ceramic piece 230 polarize the respective polarization vectors of the original disorientation along the preferred orientation of the electric field direction, because the direction of the external electric field of the first piezoelectric ceramic piece 210 is opposite to the direction of the external electric field of the second piezoelectric ceramic piece 230, the polarization direction of the first piezoelectric ceramic piece 210 is opposite to the polarization direction of the second piezoelectric ceramic piece 230, the polarization direction of the first piezoelectric ceramic piece 210 is the same as the voltage direction of the ac power supply 400, and the first piezoelectric ceramic piece 210 is elongated, so that the first piezoelectric ceramic piece 210 is bent toward the diaphragm 220; the polarization direction of the second piezoceramic sheet 230 is opposite to the voltage direction of the ac power supply 400, and the second piezoceramic sheet 230 is shortened, so that the second piezoceramic sheet 210 bends in the direction away from the diaphragm 220, and the diaphragm 220 also deforms under the action of the first piezoceramic sheet 210 and the second piezoceramic sheet, so that the piezoceramic monomer 200 assumes the first bending state.

as shown in fig. 4, when the alternating voltage direction of the ac power source 400 is output from the second electrode 420 and returns to the first electrode 410, the polarization direction of the first piezoceramic sheet 210 is opposite to the voltage direction of the ac power source 400, the first piezoceramic sheet 210 is shortened, the first piezoceramic sheet 210 is bent in the direction away from the diaphragm 220, the second piezoceramic sheet 230 is extended, the second piezoceramic sheet 210 is bent in the direction toward the diaphragm 220, and the diaphragm 220 is also deformed under the action of the first piezoceramic sheet 210 and the second piezoceramic sheet, so that the piezoceramic unit 200 assumes the second bending state.

The electronic device 20 can control the piezoelectric ceramic single body 200 to perform a deformation motion by controlling the alternating voltage of the alternating current power source 400 to switch the piezoelectric ceramic single body 200 between the first bending state and the second bending state.

wherein, the deformation amplitude of the piezoelectric ceramic single body 200 can be related to the voltage amplitude of the alternating voltage. For example, the deformation amplitude of the piezoelectric ceramic unit 200 may be proportional to the voltage amplitude of the alternating voltage. When the electronic device 20 controls the voltage amplitude of the alternating voltage of the alternating power supply 400 to increase, the deformation amplitude of the piezoelectric ceramic single body 200 increases accordingly, and stronger air fluctuation can be driven to form larger volume, so that the loudness of the audio signal is increased. Of course, the deformation amplitude of the piezoelectric ceramic single body 200 may be inversely proportional to the voltage amplitude of the alternating voltage, and in this case, the electronic device 20 may increase the deformation amplitude of the piezoelectric ceramic single body 200 by decreasing the voltage amplitude of the alternating voltage.

In the embodiment of the application, the first piezoelectric ceramic piece 210 and the second piezoelectric ceramic piece 230 are arranged in the first area, so that the second area of the diaphragm 220 is exposed outside, the first area is deformed by the acting force applied by the first piezoelectric ceramic piece 210 and the second piezoelectric ceramic piece 230, and the second area keeps the original state without the action of external force, so that the deformation amplitude of the diaphragm 220 can be increased compared with the second area without exposure.

It should be noted that the piezoelectric ceramic unit 200 may also include only the first piezoelectric ceramic piece 210 and the diaphragm 220, and the first piezoelectric ceramic piece 210 may drive the diaphragm 210 to deform. Of course, the piezoelectric ceramic unit 200 may also include a plurality of first piezoelectric ceramic pieces 210 and/or a plurality of second piezoelectric ceramic pieces 230, and the number of the first piezoelectric ceramic pieces 210 and the number of the second piezoelectric ceramic pieces 220 may be set according to practical situations, which is not limited in this embodiment of the application.

with continued reference to fig. 1, a display area, such as a display area, of the display screen 600 may be used to display a picture. The display screen 600 may have a regular shape, such as a rectangular parallelepiped structure or a rounded rectangular structure, or the display screen 600 may have an irregular shape.

The display screen 600 may have opposite display and non-display surfaces, and the plurality of piezoelectric ceramic single bodies 200 are located on the non-display surface side of the display screen 600. The display screen 600 may include a plurality of sound emitting positions such as the sound emitting position 620, and each sound emitting position 620 may be provided with one piezoelectric ceramic unit 200, and the piezoelectric ceramic unit 200 may vibrate by the ac power source 400 and drive the sound emitting position 620 to vibrate, thereby emitting sound.

Referring to fig. 5, fig. 5 is a cross-sectional structural diagram of the electronic device shown in fig. 1 along a P-P direction. The plurality of piezoelectric ceramic single units 200 may be directly fixed to the non-display surface of the display screen 600, and the fixing manner may be implemented by using an adhesive manner. For example, glue may be coated on a first end surface of the first piezoceramic sheet 210, and the first end surface of the first piezoceramic sheet 210 is attached to the non-display surface of the display screen 600. When the single piezoelectric ceramic 200 is bent toward the non-display surface of the display screen 600, the display screen 600 may be driven to bend toward the outside, and at this time, the bending state of the display screen 600 is the same as the first bending state of the single piezoelectric ceramic 200; when the single piezoelectric ceramic body is bent toward the non-display surface away from the display screen 600, the display screen 600 may be driven to be bent toward the outside, and at this time, the bent state of the display screen 600 is the same as the second bent state of the single piezoelectric ceramic body 200. Under the alternating change of the output voltage direction of the ac power supply 400, the piezoelectric ceramic single body 200 can drive the display screen 600 to switch between different bending states, so that the air around the display screen 600 flows and makes a sound. The piezoelectric ceramic single bodies 200 at different positions can drive different sound production positions 620 of the display screen 600 to vibrate, so that the sound of the electronic device 20 is emitted from different positions of the display screen 600, and when the sound production positions 620 produce sound together, a stereo effect can be created. In some embodiments, the display screen 600 may be made of a flexible material, which may increase the bending amplitude of the display screen 600 under the same driving force, thereby enhancing the sound production effect of the display screen 600.

The display screen 600 may be configured to display multiple frames of images, and the multiple frames of images may be sequentially displayed on the display area of the display screen 600 in the playing order. The multi-frame image may include a preset object image whose position on the display area changes as the playing sequence advances, such as a running car, a willow branch that moves with the wind, a running lion, a walking robot, a person who swings arms, and the like. It should be noted that the preset object image may be a preset image, such as an image of a movable object, such as a vehicle, a person, a robot, an animal, and the like, and is not limited to the above-mentioned exemplary object.

the electronic device 20 may also incorporate a processor, memory, etc., which may be used to process various operations of the electronic device 20. For example, the processor may be configured to control the display of the display screen 600, and the processor may be configured to control the vocalization of the plurality of vocalization positions 620 to change according to the position change information of the preset object image on the display area when the display area of the display screen 600 displays the preset object image.

it is understood that, during the process of displaying the image, the electronic device 20 may continuously obtain the preset object image displayed on the display screen, and emit the sound corresponding to the position change of the preset object image through the plurality of sound emitting positions 620, so as to create a stereo effect in which the sound moves along with the movement of the picture. In some embodiments, the electronic device 20 may display the images on the display screen 600 in real time according to a preset sequence, which may be a sequence set by a producer of the multi-frame images, or a sequence set by the user himself.

The electronic device can control the sound change emitted by the plurality of sound emitting positions according to the obtained position change information. The change of the sound emitted from the sound emission position may be a change of the sound emission position, such as controlling a part of the sound emission position to change from unvoiced to voiced, and a part of the sound emission position to unvoiced, a change of the volume of the emitted sound, such as increasing or decreasing the volume of the sound emitted from a part of the sound emission position, or a change of the pitch of the emitted sound, such as increasing or decreasing the pitch of the sound emitted from a part of the sound emission position.

for example, the display screen 600 is provided with 15 sounding positions in total, and the 15 sounding positions are arrayed in 3 rows × 5 columns in the width direction and the length direction of the display screen. The electronic equipment can control the sound emitted by the 15 sound-emitting positions to change according to the position change of the preset object image displayed by the display screen, for example, at the initial moment, the sound-emitting position of the first line is in a sound-emitting state, other sound-emitting positions are in a non-sound-emitting state, the electronic equipment can control the sound-emitting position of the first line to be changed from sound-emitting to non-sound-emitting, the sound-emitting position of the second line to be changed from non-sound-emitting to sound-emitting and the like according to the position change information; or the volume of the sound emitted from the sound emission position of the first row is controlled to be reduced from a value p1 to a value p2, the volume of the sound emitted from the sound emission position of the second row is controlled to be changed from 0 to a value p3, and the value p3 can be larger than the value p2, so that the sound emitted from the sound emission position of the first row is used as an auxiliary sound of the sound emitted from the sound emission position of the second row to support the sound emitted from the sound emission position of the second row; or the pitch of the sound emitted from the sound emission position of the first row is controlled to decrease from the value d1 to the value d2, the pitch of the sound emitted from the sound emission position of the second row is controlled to change from 0 to the value d3, and the value d3 may be larger than the value d2, so that the sound emitted from the sound emission position of the first row acts as the sum of the sound emitted from the sound emission position of the second row to hold back the sound emitted from the sound emission position of the second row.

In some embodiments, the electronic device 20 may control the sound emitted from the sound emission position corresponding to the position change path to follow the position change path according to a position change of the preset object image on the display area.

The electronic device may preset a first position of the object image in the display area at a first moment and a second position of the object image in the display area at a second moment, determine a position change path of the preset object image, determine a sound production position corresponding to the position change path according to the position change path, and control sound produced by the sound production position corresponding to the position change path to change according to the position change path. At this time, the electronic device may control other sound-emitting positions not to emit sound, or to emit sound of a fixed volume and/or tone.

for example, at time t1, the preset object image is displayed at the first position, and the sound emission position corresponding to the first position is the sound emission position a 1; at time t2, the preset moving image is displayed at the second position, and the sound emitting position corresponding to the second position is a sound emitting position A3, so that the position change path of the preset object image from time t1 to time t2 is as shown in fig. 6, where fig. 6 is a first application scene view of the preset object image displayed on the display screen in the embodiment of the present application.

The electronic device may determine the sound emission sequence of the sound emission position a1 → the sound emission position a2 → the sound emission position A3 according to the sound emission position corresponding to the position change path being the sound emission position a1 → the sound emission position a2 → the sound emission position A3, and control the sound emission sequence of the sound emission position a1 → the sound emission position a2 → the sound emission position A3 to change in the change direction of the position change path. For example, 3 sounding positions such as the sounding position a1 → the sounding position a2 → the sounding position A3 can be sounded sequentially, the sounding position a1 can be controlled to sound first, then the sounding position a2 can be controlled to sound, and finally the sounding position A3 can be controlled to sound. It should be noted that, when the electronic device controls the next sound production position to produce sound, the previous sound production position may be controlled not to produce sound, and the previous sound production position may also be controlled to continue to produce sound.

In some embodiments, the electronic device may further control the sound generation sequence and the sound effect of the single ceramic according to the position change path and the position change parameter of the preset object image in the display area, and control the single piezoelectric ceramic corresponding to the position change path to sequentially generate the sound corresponding to the sound effect according to the sound generation sequence and the sound effect.

The position change parameter may include a position change amplitude, a frequency of the position change, or a speed of the position change, among others. For example, as shown in fig. 6, the electronic device may detect a position change parameter from the first position to the second position from time t1 to time t2, determine a change condition of the preset object image, and control the sound emission position a1 → the sound emission position a2 → the sound emission position A3 to emit a sound adapted to the change condition, for example, control the sound emission position a1 → the sound emission position a2 → the sound emission position A3 to emit the same sound effect when the sports car is traveling at a constant speed; when the sports car is running at an accelerated speed, the sound emission position a1 → the sound emission position a2 → the sound emission position A3 is controlled to emit sounds of different sound effects to output sounds matching the running at an accelerated speed of the sports car, such as gradually rising tone or gradually rising volume. It should be noted that the sound effect may be specifically controlled according to a scene where the preset object is located, which is not limited in the embodiment of the present application.

in some embodiments, the electronic device may determine, according to the sound emission sequence, a first sound emission position set of a current sound emission and a second sound emission position set of a previous sound emission, where the first sound emission position set and the second sound emission position set respectively include at least one sound emission position, and control the first sound emission position set to emit sound and control a change of the sound emitted by the second sound emission position set according to a preset rule.

for example, as shown in fig. 7, fig. 7 is a second application scene diagram in which a preset object image is displayed on a display screen in the embodiment of the present application. At a time t4, displaying the preset moving image at a fourth position, wherein a first sounding position set corresponding to the fourth position is [ piezoelectric ceramic monomer B3 and piezoelectric ceramic monomer B4], displaying the preset object image at a third position at the time t3, and a second sounding position set corresponding to the third position is [ sounding position A1, piezoelectric ceramic monomer B1 and piezoelectric ceramic monomer B2 ]; where time t3 is the time immediately preceding time t 4. At this time, the electronic device may control the first sounding location set to sound according to a preset rule, and control a change of the sound emitted by the second sounding location set.

The method comprises the following steps of controlling the first sounding position set to make sound according to a preset rule, and controlling the second sounding position set to make sound change in the following mode: the electronic device can control the sound emitted by the piezoelectric ceramic single body according to the display area in which the target object image falls.

For example, the display area may be divided into a plurality of display sub-areas, each display sub-area is associated with each sound generation position, and at least one sound generation position corresponding to the preset moving image, such as 2 sound generation positions, 3 sound generation positions, or 4 sound generation positions, is determined according to the association relationship between each display sub-area and each sound generation position. The correspondence between the sound emission positions and the display sub-regions may be stored in advance in an electronic device such as a memory, and for example, a table may be set in advance, and one sound emission position and one display sub-region may be associated with each other according to the positional correspondence between the sound emission positions and the display sub-regions.

At time t3, the first target area is formed by the display sub-area corresponding to the first sound-emitting position set, and the electronic device can control the first sound-emitting position set to emit sound and control the second sound-emitting position set not to emit sound or emit sound of a first preset sound effect to highlight the sound of the first piezoelectric ceramic monomer when a part of the preset object image enters the first target area; the electronic device may control the first set of sound emission positions not to emit sound or to emit sound of a second preset sound effect to highlight the sound of the second set of sound emission positions and control the second set of sound emission positions to emit sound when a portion of the preset object image does not enter the first target area. The first preset sound effect and the second preset sound effect can be set according to a scene where a preset object image is located currently, for example, environmental sounds such as wind sounds and rain sounds, or sounds with different tones or volumes.

The method comprises the following steps of controlling the first sounding position set to make sound according to a preset rule, and controlling the change of the sound made by the second sounding position set, wherein the change of the sound made by the first sounding position set can be realized by the following steps:

when the preset object image is located at the first position, controlling the third sounding position set to sound, and controlling the fourth sounding position set not to sound;

When the preset object image is located at the second position, controlling the fourth sounding position set to sound, and controlling the third sounding position set not to sound;

And when the preset object image is positioned between the first position and the second position, controlling the sounding changes of the third sounding position set and the fourth sounding position set according to a preset rule.

Referring to fig. 6, at time t1, the preset moving image is displayed at the first position, and the third sounding positions corresponding to the first position are collected as the sounding position a1, at which time the electronic device may control the sounding position a1 to sound and control the sounding position A3 not to sound. At the time t2, the preset moving image is displayed at the second position, and the fourth sounding positions corresponding to the second position are collected to be the sounding position A3, at this time, the electronic device may control the sounding position A3 to sound and control the sounding position a1 not to sound.

It can be understood that, in the embodiment of the present application, to which position of the display area the preset object image changes, and which position corresponds to the sound production position to produce the sound, a stereo effect is created in which the sound moves along with the movement of the image. The present embodiment differs from the above-described embodiments in that, when the position is changed from the first position to the second position, the sound emitted from the sound emission position at the intermediate interval is not processed, for example, the sound emission position a2 located between the sound emission position a1 and the sound emission position A3 is not processed, and the sound emission position a2 can be maintained in the non-sound emission state. The electronic equipment can acquire the position of the preset object image in real time, and control the sound production position corresponding to the current position to produce sound according to the change of the position, the sound production position corresponding to the previous position does not produce sound, the change path between the two positions does not need to be calculated, and the processing efficiency of the electronic equipment can be improved.

in some embodiments, "controlling the sounding changes of the third and fourth sounding positions according to a preset rule when the preset object image is located between the first position and the second position" may include:

Acquiring the distance between the preset object image and the first position;

Judging whether the distance between the preset object image and the first position is equal to or greater than a preset distance;

When the distance between the preset object image and the first position is equal to or larger than the preset distance, controlling the third sounding position set not to sound and controlling the fourth sounding position set to sound;

and when the distance between the preset object image and the first position is smaller than the preset distance, controlling the third sounding position set to sound and controlling the fourth sounding position set not to sound.

Because the sound production positions are arranged at a certain distance, when the preset object image is positioned between the two sound production positions, the electronic equipment can determine the sound production position corresponding to the preset object image to produce sound according to the preset rule.

For example, as shown in fig. 8, fig. 8 is a third application scene diagram in which a preset object image is displayed on a display screen in the embodiment of the present application. At time t5, the preset object image is located between the third set of sound emission positions and the fourth set of sound emission positions, and the electronic device may determine the change in sound emission from the sound emission positions according to the distance between the preset object image and the sound emission position a 1.

When the preset object image is located between the third sounding position set and the fourth sounding position set, the electronic device may obtain a distance d1 between the preset object image and the first position, determine whether the distance d1 is greater than or equal to the preset distance, control the third sounding position set (sounding position a1) not to sound if the distance d1 is greater than or equal to the preset distance, and control the fourth sounding position set (sounding position A3) to sound; and controlling the third sounding position set (sounding position a1) to sound and the fourth sounding position set (sounding position A3) not to sound if the distance d1 is less than the preset distance.

In some embodiments, "controlling the sounding changes of the third sounding position set and the fourth sounding position set according to a preset rule when the preset object image is located between the first position and the second position" may also include:

Acquiring the distance change between the preset object image and the first position;

according to the distance change between the preset object image and the first position, the volume change of the sound emitted by the third sound emission position set and the volume change of the sound emitted by the fourth sound emission position set are respectively controlled, so that when the preset object image is gradually far away from the first position, the volume of the sound emitted by the third sound emission position set is gradually reduced, and the volume of the sound emitted by the fourth sound emission position set is gradually increased.

When presetting the object image and being located between third sound production position set and the fourth sound production position set, electronic equipment can make third sound production position set and fourth sound production position set sound simultaneously to acquire the distance change between presetting the object image and the first position in real time, according to this distance change control third sound production position set and the volume of the sound that the fourth sound production position set sent, make and preset the object image and keep away from gradually during the first position, the volume of the sound that third sound production position set sent reduces gradually, and the volume of the sound that the fourth sound production position set sent increases gradually, and the sound signal of avoiding electronic equipment to send is discontinuous, can guarantee the continuity of the sound that electronic equipment sent, can build a stereo effect again.

in some embodiments, the electronic device may also perform control of the sounds emitted by the third sound emission position set and the fourth sound emission position set according to an area value of a display sub-region occupied by a preset object image.

For example, the electronic device may preset a preset threshold, when the preset object image is displayed on the plurality of display sub-regions at the same time, the processor may determine the display areas of the plurality of display sub-regions one by one, determine whether the display area of the display sub-region is greater than or equal to the preset threshold, and control the corresponding piezoelectric ceramic monomer to sound when the display area of the display sub-region is greater than or equal to the preset threshold; and when the display area of the display sub-area is smaller than a preset threshold value, controlling the corresponding piezoelectric ceramic monomer not to sound.

As shown in fig. 9, fig. 9 is a fourth application scene diagram of a preset object image displayed on a display screen in the embodiment of the present application. The preset object image is displayed in two display sub-regions, such as the display sub-region s1 and the display sub-region s2, at the same time, assuming that the display area of the preset object image in the display sub-region s1 is 1 square centimeter, the display area in the display sub-region s2 is 0.4 square centimeter, and the preset threshold value is 0.5 square centimeter, the processor controls the sound production position a1 corresponding to the display sub-region s1 to produce sound, and controls the sound production position a2 corresponding to the display sub-region s 1.

The areas of the display sub-regions may be equal or unequal. For example, the area of the display sub-region at the middle position of the display region may be set smaller than the area of the display sub-region at the side position of the display region, so as to improve the control accuracy of the center position of the display region.

It should be noted that the area value of the display sub-area or the distance value between the preset object image and the display position at the previous time and the distance variation value described in the above application embodiment are only exemplary illustrations of preset rules, which may be specifically set according to image data to be played, the electronic device may also set various rules for a user to select by himself when leaving a factory, and the electronic device may control the sound emitted by the plurality of piezoelectric ceramic single bodies according to the rule selected by the user.

The sound volume of the piezoelectric ceramic single body 200 can be controlled by controlling the sound production amplitude of the piezoelectric ceramic single body according to the specific scene of the preset object image. For example, the sound production amplitude of the sound production position A1 can be controlled to be smaller than that of the sound production position A3, so that the sound volume of the first position is smaller than that of the second position, a sound volume effect matched with the current scene is created, and the viewing experience of the user is improved. For example, when the display area shows that the leading woman is shored due to frightening, the sound volume of the corresponding sound production position can be increased according to the scene so as to create the sound effect suitable for the display content. The processor may adjust the amplitude of the voltage output by the ac power supply 400, and then adjust the amplitude of the deformation of the piezoelectric ceramic single body 200 to adjust the amplitude of the deformation of the sounding position 620, thereby adjusting the sounding volume of the sounding position.

electronic equipment 20 of this application embodiment is through setting up a plurality of vocal positions 620, the vocal of a plurality of vocal positions 620 can change according to predetermineeing the position change of object image on the display area, predetermine the stereo dynamic effect that object image realized self-adaptation display content, compare in only setting up a speaker, when playing multiframe image, audio signal can only follow the correlation technique that the position that this speaker corresponds was exported, the sound effect of multiframe image broadcast can be improved to this application embodiment, improve user's viewing experience.

In some embodiments, controlling the sound variation emitted by the sound emission position according to the position variation information may further include:

when the preset object image is displayed at the first position of the display screen, controlling the sound production position corresponding to the first position to produce sound with different sound effects and controlling other sound production positions not to produce sound according to the first distance between each sound production position corresponding to the first position and the preset object image;

when the preset object image is displayed at the second position of the display screen, according to each sounding position corresponding to the second position and the second distance between the preset object images, the sound of different sound effects is sent out by the sounding position corresponding to the second position, and other sounding positions are controlled not to send out sound.

for example, when the display position of the preset object image in the display area is relatively large, a plurality of sound production positions may be occupied at the same time, and at this time, the electronic device may control a plurality of sound production positions corresponding to the preset object image to produce sounds of different sound effects according to the distance between the sound production positions and the preset object image. For example, when the preset object image is a leading girl corner of a tv series, and the leading girl corner is displayed at the first position, the corresponding first position may include [ sound emission position a2, sound emission position A3, sound emission position B2, sound emission position B3, sound emission position C2, and sound emission position C3], at this time, the electronic device may measure a distance between each sound emission position and the leading girl corner, where the distance may be a distance between the sound emission position and a center position of the preset object image, or a distance between the sound emission position and a sound emission source of the preset object image (for example, mouth). For example, when the mouth of the female hero is located at the sound generating position C3, the electronic device may control the sound generating position C3 to generate the first preset sound effect, and control the other sound generating positions to generate the second preset sound effect, so as to set off the sound of the first preset sound effect, for example, the volume and/or tone of the first preset sound effect may be higher than the volume and/or tone of the second preset sound effect. The electronic device may further control the sound volume of the sound emission position (such as the sound emission position a2 and the sound emission position A3) farther from the preset object image to be the smallest and the tone to be the lowest according to the distance; controlling the sound volume of the sound production position (such as the sound production position B2 and the sound production position B3) closer to the preset object image to be smaller and the tone to be lower; controlling the sound volume of the sound production position (such as the sound production position C2) closest to the preset object image to be minimum and the tone to be minimum; and controls other sound production positions not to produce sound. Correspondingly, when the female leading role is displayed at the second position, the sound production position corresponding to the second position is controlled to produce sound with different sound effects, and other sound production positions are controlled not to produce sound.

The electronic equipment in the above-mentioned application embodiment can also be in when the position of making a sound is for making a sound the state, acquire the position of making a sound with predetermine the distance of object image, and according to each is confirmed to the distance the sound effect mode of position of making a sound, the sound effect mode includes the size of volume and/tone.

For example, the electronic device may preset a preset value, such as a first preset value and a second preset value, and when the distance is smaller than the first preset value, the sound production position is controlled to produce the sound of the first sound effect mode.

for example, when the sound effect mode of the sound production position is the second sound effect mode, the volume of the sound production position is controlled to be larger than a fourth preset value and smaller than the second preset value and/or the tone of the sound production position is controlled to be larger than a fifth preset value and smaller than the third preset value.

and when the distance is greater than the first preset value, controlling the sound production position to produce the sound of the second sound effect mode so as to highlight the sound produced by the sound production position producing the first sound effect mode.
