Detailed Description

The embodiment of the present application provides a sound production control method, where an execution main body of the sound production control method may be an electronic device provided in the embodiment of the present application, such as the electronic device 20 shown in fig. 1, and fig. 1 is a schematic structural diagram of the electronic device provided in the embodiment of the present application. 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. The piezoelectric ceramic single body 200 may convert mechanical energy and electrical energy into each other, and when the piezoelectric ceramic single body 200 converts electrical energy into mechanical energy, the piezoelectric ceramic single body 200 may output a sound signal, and at this time, the piezoelectric ceramic single body 200 may serve as an earpiece or a speaker of the electronic device 20; when the piezoelectric ceramic single body converts mechanical energy into electrical energy, the piezoelectric ceramic single body 200 may collect a sound signal, and at this time, the piezoelectric ceramic single body 200 may serve as a microphone of the electronic device 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 supply 400 may change with time along with the direction, the piezoelectric ceramic single body 200 may perform a deformation motion along with the alternating voltage direction, and the deformation motion of the piezoelectric ceramic single body 200 may cause ambient air to flow, thereby emitting sound.

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 plurality of piezoelectric ceramic units 200 may be arranged in an array to form a sound emitting area 240. The piezoelectric ceramic single bodies 200 may be distributed in a rectangular array along the length direction and the thickness direction of the electronic device 20 to form a rectangular sound emitting area 240.

For example, a plurality of piezoelectric ceramic single cells 200 may be arranged at intervals in the width direction and the length direction of the electronic device 20 to form M sound emission rows and N sound emission columns, which constitute the M × N sound emission area 240. Where M may be equal to N, such as M-N-3. Of course M may not be equal to N. Wherein, one piezoelectric ceramic single unit 200 in the plurality of piezoelectric ceramic single units may be equal to the spacing between other piezoelectric ceramic single units 200 adjacent to the piezoelectric ceramic single unit. The positional adjacency may be one or more of laterally adjacent, longitudinally adjacent, or diagonally adjacent. Of course, the distance between one piezoelectric ceramic single unit 200 of the plurality of piezoelectric ceramic single units and the other piezoelectric ceramic single units 200 adjacent to the piezoelectric ceramic single unit may not be equal.

As shown in fig. 1, electronic device 20 may also include a display screen, such as display screen 600. A display area of display screen 600, such as display area 620, 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. For example, the electronic device 20 is provided with a housing chamber in which the plurality of piezoelectric ceramic single bodies 200 are housed. The piezoelectric ceramic single body 200 can perform a deformation motion in the receiving cavity, so that air around the piezoelectric ceramic single body 200 flows, thereby generating sound.

The display area 620 overlaps with the projection of the sound emission area 240 on the display screen 600. Such as: the size of the display area 620 may be smaller than the size of the sound emission area 240, and a portion of the projection of the sound emission area 240 on the electronic device 20 may overlap the display area 620 and another portion may overlap a non-display area of the display screen 600, such as the non-display area 640. It is understood that a part of the piezoelectric ceramic single cells 200 of the plurality of piezoelectric ceramic single cells 200 is located in the display region 620, and another part of the piezoelectric ceramic single cells 200 is located in the non-display region 640. For another example: the size of the display area 620 may also be equal to the size of the sound emission area 240, with the display area 620 completely overlapping the projection of the sound emission area 240 on the display screen 600. It is understood that the projections of the plurality of piezoelectric ceramic single cells 200 on the display screen 600 are all located in the display area 620. In this case, the display 600 may or may not include the non-display area 640, and when the display 600 does not include the non-display area 640, the entire area of the display surface of the display 600 is used as the display area 620, thereby achieving the effect of full-screen display.

Referring to fig. 5, fig. 5 is a first cross-sectional structure 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. A first gap 820 is left between the first end surface of the first piezoelectric ceramic piece 210 and the non-display surface, and the first gap 820 may provide a deformation space for the piezoelectric ceramic unit 200, so that the piezoelectric ceramic unit 200 may be bent toward the non-display surface or may be bent away from the non-display surface. In some embodiments, the glue may be coated on a second region of the diaphragm 220, the second region is adhered to the non-display surface of the display screen 600, and the first piezoelectric ceramic sheet 210 abuts against the non-display surface, so as to fix the piezoelectric ceramic unit 200, and enable the first piezoelectric ceramic sheet 210 to bend freely, and only fix two sides of the diaphragm 220, and also increase the bending amplitude of the diaphragm 220 when the diaphragm 220 is under the action of the piezoelectric ceramic sheet.

With continued reference to fig. 1, the electronic device 20 may further include a housing, such as housing 900, with the display screen 400 mounted on the housing 900. The housing 900 may be formed from plastic, glass, ceramic, fiber composite, metal (e.g., stainless steel, aluminum, etc.), other suitable materials, or a combination of any two or more of these materials. The housing 900 has an inner surface and an outer surface, wherein the inner surface may be a surface on which the components of the electronic device 20 are mounted, and the outer surface may be located outside the electronic device 20. For example, the outer surface of the housing 900 is visible to a user and the inner surface of the substrate 900 is not visible to the user.

Alternatively, as shown in fig. 6, fig. 6 is a second cross-sectional structural view of the electronic device shown in fig. 1 along the P-P direction. The piezoelectric ceramic single body 200 of the above-mentioned application embodiment may also be directly fixed to the inner surface of the housing 900, and may be implemented by using an adhesive. For example, the fourth end surface of the second piezoceramic sheet 230 may be directly bonded to the inner surface of the housing 900. Similarly, a second gap 840 is left between the fourth end surface and the inner surface of the second piezoceramic sheet 220, and the second gap 840 may provide a deformation space for the single piezoceramic cell 200, so that the single piezoceramic cell 200 may be bent towards the inner surface or away from the inner surface. In some embodiments, glue may be coated on the second region of the diaphragm 220, the second region is adhered to the inner surface of the casing 900, and the second piezoceramic sheet 230 abuts against the inner surface, so as to fix the single piezoceramic sheet 200, and allow the second piezoceramic sheet 230 to bend freely, and only fix the two sides of the diaphragm 220, and also increase the bending amplitude of the diaphragm 220 when the diaphragm 220 is acted by the piezoceramic sheet.

As shown in fig. 7, fig. 7 is a third cross-sectional structure diagram of the electronic device shown in fig. 1 along the P-P direction. The plurality of piezoelectric ceramic single units 200 in the above-mentioned embodiments may be disposed on both the display screen 600 and the housing 900. For example, the plurality of piezoelectric ceramic single bodies 200 may be divided into two parts, one of which is disposed on the non-display surface of the display screen 600, and a projection of a part of the piezoelectric ceramic single bodies 200 on the display screen overlaps with the display area 620 of the display screen; another part is disposed on the inner surface of the casing 900, and another part of the piezoelectric ceramic single bodies may be located at the interval position of one part of the piezoelectric ceramic single bodies 200, and the projection of another part of the piezoelectric ceramic single bodies 200 on the display screen overlaps with the display area 620 of the display screen. Therefore, the control accuracy of the sound emitted by the piezoelectric ceramic single body 200 can be increased, the piezoelectric ceramic single body 200 arranged on the non-display surface of the display screen 600 can emit sound towards the display surface of the display screen 600, the piezoelectric ceramic single body 200 arranged on the inner surface of the shell 900 can emit sound towards the outer surface of the shell 900, and the sound emission effect of the electronic device 20 is further improved.

The display screen 600 may be used to display multiple frames of images, and the multiple frames of images may be sequentially displayed on the display area 620 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 sounding of the piezoelectric ceramic units 200 to change along with a change in the position of the preset object image on the display area 620 when the display area 620 of the display screen 600 displays the preset object image.

It can be 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 adapted to the position change of the preset object image through the plurality of piezoelectric ceramic monomers 200, 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.

In some embodiments, the electronic device 20 may control the piezoelectric ceramic single cells 200 corresponding to the display positions of the preset object image to emit the sound according to the arrangement of the plurality of piezoelectric ceramic single cells 200 in the electronic device 20. For example, the plurality of piezoelectric ceramic cells 200 may include a piezoelectric ceramic cell a1, a piezoelectric ceramic cell a2, a piezoelectric ceramic cell A3, a piezoelectric ceramic cell a4, and a piezoelectric ceramic cell a5, which are located in the same row, the piezoelectric ceramic cell a1, the piezoelectric ceramic cell a2, the piezoelectric ceramic cell A3, the piezoelectric ceramic cell a4, and the piezoelectric ceramic cell a5 are arranged in an array along the length direction of the display screen, the piezoelectric ceramic cell a1 may emit a first sound corresponding to the display position a1, the piezoelectric ceramic cell a2 may emit a second sound corresponding to the display position a2, the piezoelectric ceramic cell A3 may emit a third sound corresponding to the display position A3, the piezoelectric ceramic cell a4 may emit a fourth sound corresponding to the display position a4, the piezoelectric ceramic cell a5 may emit a fifth sound corresponding to the display position a5, where the arrangement of the piezoelectric ceramic cells corresponds to the display positions of the display area one by one, the processor can control the sound emitted by the corresponding piezoelectric ceramic monomer to change according to the position change of the preset object image displayed on the display area.

The following is a detailed description of the analysis.

Referring to fig. 8, fig. 8 is a first flowchart of a sound emission control method according to an embodiment of the present disclosure, where the sound emission control method may be applied to the electronic device shown in fig. 1, and the sound emission control method includes:

and 101, acquiring two frames of preset object images displayed in the display area.

When the electronic equipment is used for watching videos, the display area of the display screen can sequentially display target scene images according to the video playing sequence, and the electronic equipment can obtain two frames of preset object images containing preset objects from the target scene images. The two frames of preset object images are respectively displayed on the display area at different moments. For example, the electronic device may acquire two frames of preset object images by: the electronic device can acquire a first image and a second image displayed on the display area, and respectively recognize a preset object image at a first moment from the first image and recognize a preset object image at a second moment from the second image.

The preset object image may be a preset image of an object, for example, if the preset object is a sports car, the preset object image is a sports car image, if the preset object is a female hero, the preset object image is an image of the female hero, and if the preset object is a robot, the preset object image is an image of the robot. The electronic device may acquire a preset object image in advance, and recognize the preset object image to obtain m key points. It should be noted that the preset object image may be one object or a plurality of objects, for example, the image of the sports car and the image of the hero of the woman may be simultaneously set as the preset object image, or the image of the hero of the man and the image of the hero of the woman may be simultaneously set as the preset object image, which may be set according to the desired scene effect.

The preset object image can be recognized from the display image according to the m key points in the electronic device, for example, the electronic device may preset a feature recognition model, and the feature recognition model may perform feature recognition on the acquired first image and the acquired second image. For example, the electronic device may preset a convolutional neural network model, identify key points of a preset object image in the first image by using the convolutional neural network model to obtain a plurality of feature values of the preset object image, and identify the preset object image at the first time from the first image by using the plurality of feature values. Accordingly, the preset object image at the second moment is identified from the second image through the feature identification model.

In this scheme, the target scene image refers to an image to be played by a user through the electronic device, and the target scene image may be presented in a display area of the display screen.

In addition, the content of the target scene image is not specifically limited in the embodiment of the present application, for example, the target scene image may be that a sports car runs on an expressway, that a sports car runs on a rural area, that a sports car runs in a car race track, or the like. The method of the embodiment of the application can be used in any scene needing to use the display screen for image display. For example, video playback is performed using video playback software, live broadcast is performed using live broadcast software, and the like.

102, determining a first position and a second position of the preset object image on the display area according to two frames of the preset object image;

103, determining position change information of the preset object image on the display area according to the first position and the second position.

The first position is a position where the preset object image is displayed at the first moment, the second position is a position where the preset object image is displayed at the second moment, and the position change information may include a change in position, a changed path, a changed amplitude, and the like.

For example, at the first time, the electronic device may recognize the display position of the preset object image to recognize the first position. At the second time, the electronic device may identify the display position of the preset object image to identify the second position, and determine position change information of the preset object on the display area according to the first position and the second position, such as a change path from the first position to the second position, where the change path refers to a directional road segment passing through the display position from the first position to the second position, and the position change path is continuous. The position change may refer to a position where the preset object image passes, such as a set of passing first, second, and third positions, such as [ a1, b1, c1 … n1], which is a set of spaced points. The position change amplitude refers to a change amount in a unit time, for example, a position change amount of the preset object image from the first position to the second position is 1 cm from the first time to the second time.

104, controlling the sound emitted by the plurality of piezoelectric ceramic monomers to change according to the position change information.

The electronic device can control the sound emitted by the piezoelectric ceramic single bodies to change according to the obtained position change information. The change of the sound emitted by the piezoelectric ceramic single body may be a change of a sound emission position, such as controlling a part of the piezoelectric ceramic single body to change from non-sound emission to sound emission, and a part of the piezoelectric ceramic single body to change from sound emission to non-sound emission, a change of the sound volume of the emitted sound, such as increasing or decreasing the sound volume of the emitted sound of the part of the piezoelectric ceramic single body, or a change of the sound pitch of the emitted sound, such as increasing or decreasing the sound pitch of the emitted sound of the part of the piezoelectric ceramic single body.

For example, the electronic device is provided with 15 piezoelectric ceramic single bodies, and the 15 piezoelectric ceramic single bodies are arrayed in 3 rows × 5 columns along the width direction and the length direction of the display screen. The electronic equipment can control the sound emitted by 15 piezoelectric ceramic monomers to change according to the position change of a preset object image displayed by the display screen, for example, at the initial moment, the piezoelectric ceramic monomers in the first row are in a sound production state, other piezoelectric ceramic monomers are in a non-sound production state, the electronic equipment can control the piezoelectric ceramic monomers in the first row to change from sound production to non-sound production, the piezoelectric ceramic monomers in the second row from non-sound production to sound production and the like according to the position change information; or the volume of the sound emitted by the piezoelectric ceramic single bodies in the first row is controlled to be reduced from a value p1 to a value p2, the volume of the sound emitted by the piezoelectric ceramic single bodies in 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 by the piezoelectric ceramic single bodies in the first row serves as an auxiliary sound of the sound emitted by the piezoelectric ceramic single bodies in the second row to support the sound emitted by the piezoelectric ceramic single bodies in the second row; or the tone of the sound emitted by the piezoelectric ceramic single bodies in the first row is controlled to be reduced from the value d1 to the value d2, the tone of the sound emitted by the piezoelectric ceramic single bodies in the second row is controlled to be changed from 0 to the value d3, and the value d3 can be larger than the value d2, so that the sound emitted by the piezoelectric ceramic single bodies in the first row is used as the sum sound of the sound emitted by the piezoelectric ceramic single bodies in the second row to support the sound emitted by the piezoelectric ceramic single bodies in the second row.

For example, 3 piezoelectric ceramic monomers such as piezoelectric ceramic monomer a1 → piezoelectric ceramic monomer a2 → piezoelectric ceramic monomer A3 can sound in sequence, and the piezoelectric ceramic monomer a1 can be controlled to sound first, then the piezoelectric ceramic monomer a2 can be controlled to sound, and finally the piezoelectric ceramic monomer A3 can be controlled to sound. It should be noted that, when the electronic device controls the next piezoelectric ceramic monomer to sound, the previous piezoelectric ceramic monomer may be controlled not to sound, and the previous piezoelectric ceramic monomer may also be controlled to continue to sound.

At a time t4, displaying the preset moving image at a fourth position, displaying a preset object image at a third position at a first piezoelectric ceramic module corresponding to the fourth position as [ piezoelectric ceramic monomer B3 and piezoelectric ceramic monomer B4], and displaying a preset object image at a third position at a time t3, wherein the second piezoelectric ceramic module corresponding to the third position as [ piezoelectric ceramic monomer 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 piezoelectric ceramic module to make a sound according to a preset rule, and control a change of the sound made by the second piezoelectric ceramic module.

For example, the display area may be divided into a plurality of display sub-areas, each display sub-area is associated with each single piezoelectric ceramic, and at least one single piezoelectric ceramic corresponding to the preset moving image, such as 2 single piezoelectric ceramic, 3 single piezoelectric ceramic, or 4 single piezoelectric ceramic, is determined according to the association relationship between each sub-area and each single piezoelectric ceramic.

Referring to fig. 12, fig. 12 is a third flow chart of an utterance control method according to an embodiment of the present application, where the utterance control method includes:

At the time t2, the preset moving image is displayed at the second position, the fourth piezoelectric ceramic module corresponding to the second position is the piezoelectric ceramic monomer A3, and at this time, the electronic device can control the piezoelectric ceramic monomer A3 to make a sound and control the piezoelectric ceramic monomer a1 not to make a sound.

It can be understood that, in the embodiment of the present application, the preset object image changes to which position of the display area, and the piezoelectric ceramic monomer corresponding to which position generates the sound, so as to create a stereo effect that the sound moves along with the movement of the image. The present embodiment differs from the above-mentioned embodiments in that the sound emitted from the piezoelectric ceramic unit at the middle interval is not processed when the piezoelectric ceramic unit changes from the first position to the second position, for example, the piezoelectric ceramic unit a2 between the piezoelectric ceramic unit a1 and the piezoelectric ceramic unit A3 is not processed, and the piezoelectric ceramic unit a2 can be maintained in a non-sound state. The electronic equipment can acquire the position of the preset object image in real time, and control the piezoelectric ceramic monomer corresponding to the current position to make a sound according to the change of the position, the piezoelectric ceramic monomer corresponding to the previous position does not make a 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 sound emission changes of the third piezoelectric ceramic module and the fourth piezoelectric ceramic module 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 piezoelectric ceramic module not to make a sound, and controlling the fourth piezoelectric ceramic module to make a sound;

and when the distance between the preset object image and the first position is smaller than the preset distance, controlling the third piezoelectric ceramic module to make a sound, and controlling the fourth piezoelectric ceramic module not to make a sound.

Because the piezoelectric ceramic monomers are arranged at a certain distance, when a preset object image is positioned between the two piezoelectric ceramic monomers, the electronic equipment can determine the piezoelectric ceramic monomers corresponding to the preset object image to make a sound according to a preset rule.

For example, as shown in fig. 13, fig. 13 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 piezoelectric ceramic module and the fourth piezoelectric ceramic module, and the electronic device may determine the change of the sound emitted by the piezoelectric ceramic unit according to the distance between the preset object image and the piezoelectric ceramic unit a 1.

When the preset object image is located between the third piezoelectric ceramic module and the fourth piezoelectric ceramic module, 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 a preset distance, control the third piezoelectric ceramic module (piezoelectric ceramic monomer a1) not to make a sound if the distance d1 is greater than or equal to the preset distance, and control the fourth piezoelectric ceramic module (piezoelectric ceramic monomer A3) to make a sound; and if the distance d1 is smaller than the preset distance, controlling the third piezoelectric ceramic module (piezoelectric ceramic monomer A1) to make a sound, and controlling the fourth piezoelectric ceramic module (piezoelectric ceramic monomer A3) not to make a sound.

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 piezoelectric ceramic module and the volume change of the sound emitted by the fourth piezoelectric ceramic module 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 piezoelectric ceramic module is gradually reduced, and the volume of the sound emitted by the fourth piezoelectric ceramic module is gradually increased.

When presetting the object image and being located between third piezoelectric ceramic module and the fourth piezoelectric ceramic module, electronic equipment can make third piezoelectric ceramic module and fourth piezoelectric ceramic module send 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 piezoelectric ceramic module and the volume of the sound that the fourth piezoelectric ceramic module sent, make and preset the object image and keep away from gradually when the first position, the volume that the third piezoelectric ceramic module sent sound reduces gradually, and the volume that the fourth piezoelectric ceramic module sent sound increases gradually, avoids the sound signal discontinuity that electronic equipment sent, 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 control the sound emitted by the third piezoelectric ceramic module and the fourth piezoelectric ceramic module 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. 14, fig. 14 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 piezoelectric ceramic monomer a1 corresponding to the display sub-region s1 to sound, and controls the piezoelectric ceramic monomer 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 piezoelectric ceramic monomer A1 can be controlled to be smaller than that of the piezoelectric ceramic monomer 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 watching experience of a 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 piezoelectric ceramic monomer can be increased according to the scene to create the sound effect suitable for the display content. The processor can adjust the deformation amplitude of the piezoelectric ceramic single body 200 by adjusting the voltage amplitude output by the alternating current power supply 400, so as to adjust the sound volume of the piezoelectric ceramic single body 200.
