[0033] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0037] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0038] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0039] The embodiments of the present disclosure provide a control method and an electronic device. Before introducing the technical solutions provided by the embodiments of the present disclosure, the related technologies involved in the present disclosure are first described.

[0040] In the related art, in some usage scenarios such as voice calls and online conferences, when an electronic device makes a sound, sound leakage usually occurs on the left and right sides of the audio receiver, which can easily affect others and leak the user's privacy, affecting the user's experience.

[0041] Exemplarily, the related electronic device realizes directional sound emission of the electronic device by introducing a sound focusing screen. Figure 1A , the display unit of the relevant electronic device can be a sound-gathering screen, and the sound-emitting panel can be the panel of the sound-gathering screen. The sound-gathering screen is an innovative fusion of display and audio technologies. It does not require traditional speakers and directly uses the screen itself as a sound-emitting unit to achieve directional sound from the screen. The sound-gathering screen 100 includes a left channel (left sound-emitting unit) and a right channel (right sound-emitting unit) arranged at intervals. The sound-gathering screen 100 is used to optimize the sound produced by the left channel and the right channel to make its propagation more uniform and targeted. However, since directional sound uses ultrasound as a carrier, the straight-line propagation distance is long, and there will be some sound leakage on the left and right sides of the audio receiver. For example, referring to Figure 1B When the sound-focusing screen outputs the sound generated by the left and right channels, the sound intensity near the ear of the audio receiver is about 76dB, behind the audio receiver, the sound intensity is about 60dB, to the left of the audio receiver, the sound intensity is about 68.4dB, and to the right of the audio receiver, the sound intensity is about 69dB. This intensity of sound can easily affect other people and leak the user's privacy, thus affecting the user's experience.

[0042] The embodiments of the present disclosure provide a control method, which is applied to an electronic device, and the method includes: in response to obtaining contour information of a target object, determining a sound unit of the electronic device corresponding to a target sound field based on the contour information; controlling a driving unit of the electronic device to drive the sound unit to vibrate, so that the sound unit outputs a target sound in the target sound field; wherein the intensity of the target sound in the target sound field is greater than the intensity of the target sound outside the target sound field, and the target sound field is an area including the target object. The number and position of the sound units are automatically adapted according to the contour information of the target object. Not only can it avoid turning on redundant sound units and reduce energy consumption; it can also enhance the directionality of the sound emitted by the electronic device, effectively reduce the sound leakage problem on the left and right sides of the target object, and improve the user experience.

[0043] The following will be passed Figure 2A to Figure 6 The control method of the disclosed embodiment is described in detail.

[0044] Figure 2AOne of the flow charts of the control method according to the embodiment of the present disclosure is schematically shown. Figure 2B One of the schematic diagrams of profile information according to an embodiment of the present disclosure is schematically shown. Figure 2C The second schematic diagram schematically shows the profile information according to an embodiment of the present disclosure. Figure 2D A schematic diagram of a target sound field according to an embodiment of the present disclosure is schematically shown.

[0045] like Figure 2A As shown, the control method of this embodiment is applied to an electronic device, and the control method includes operations S210 to S220.

[0046] The electronic device may be any device with an audio playback function, for example, a speaker, a music player, a handheld game console, a mobile phone, a tablet computer, a wearable device such as a smart watch, a smart bracelet, a Bluetooth headset, etc., a smart home device such as a TV, a smart screen, a game console, a smart speaker, a smart projector, a smart TV box, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), etc. The disclosed embodiments do not impose any special restrictions on the specific device form of the electronic device.

[0047] In operation S210, in response to obtaining contour information of a target object, a sound emission unit of an electronic device corresponding to a target sound field is determined based on the contour information.

[0048] The target sound field is an area including the target object.

[0049] Exemplarily, the target object may refer to the receiver of the audio data when the electronic device plays the audio data. The target object may be one or more. For example,

[0050] Contour information can be visual information that describes the shape and structure of the object boundary. It can be understood as the edge and boundary between the target object and the surrounding background. Here, the contour information does not need to be too detailed, and it can roughly reflect the size information of different parts of the target object.

[0051] The outline can be a simple shape or a complex irregular shape. Figure 2B , the outline 1 of user A may be a rectangle, the outline 2 of user B and the outline 3 of user C may be T-shaped.

[0052] The contour information may be the contour information of the entire target object or the contour information of a part of the target object. Figure 2B , user A uses partial contour information, namely, the contour of the upper part of user A's body.

[0053] In the case of multiple target objects, it is not necessary to distinguish each target object, but multiple target objects can be treated as a whole. The outline information can be the outline information displayed after multiple target objects overlap. The outline includes multiple target objects. Figure 2C When user A and user B use the electronic device at the same time, the profile information of user A and user B may be as shown in profile 4.

[0054] The contour information of the target object may be acquired by components on the electronic device, or may be acquired by external components and then transmitted to the electronic device.

[0055] The target sound field can be the area or space where the sound generated by the electronic device is focused on the target object. Figure 2D , the sound generated by the electronic device can be transmitted in the area where user A is located, and the sound generated by the electronic device cannot be heard on the left and right sides of user A, or the heard sound is very weak.

[0056] The sound-generating unit may be a component that converts an electrical signal into sound. The sound-generating unit usually causes air fluctuations through mechanical vibrations, thereby forming sound waves. For example, the sound-generating unit may be a speaker or the like.

[0057] The electronic device may have one sound unit or multiple sound units. The embodiment of the present disclosure does not specifically limit the number of sound units.

[0058] One or more sound-emitting units are determined by the contour information of the target object to realize the directional sound emission of the electronic device to the target object. That is, the number and position of the sound-emitting units that can propagate sound in the area where the target object is located are determined by the contour information of the target object.

[0059] For example, user A uses a tablet computer to play music. The tablet computer uses a sound-gathering screen with multiple sound-emitting units. The tablet computer collects the profile information of user A, analyzes the profile information of user A, obtains the target sound field of the area where user A is located, and then determines one or more sound-emitting units that can propagate sound in the target sound field.

[0060] In operation S320, the driving unit of the electronic device is controlled to drive the sound generating unit to vibrate so that the sound generating unit outputs a target sound within a target sound field.

[0061] The intensity of the target sound in the target sound field is greater than the intensity of the target sound outside the target sound field.

[0062] Exemplarily, the driving unit may be a component that drives the sound generating unit to generate vibrations to form sounds. The driving unit may be driven by electromagnetic, electrostatic, piezoelectric, electrodeformation, etc. For example, electromagnetic drive: when an audio signal passes through the voice coil, the current interacts with the fixed magnet to generate a magnetic field, causing the voice coil to move up and down in the magnetic field, thereby driving the diaphragm to vibrate and generate sound waves.

[0063] The number of driving units may be the same as the number of sound-emitting units. For example, one driving unit corresponds to one sound-emitting unit, that is, one driving unit can drive the corresponding sound-emitting unit to vibrate and produce sound. In the case where there are M sound-emitting units, N sound-emitting units corresponding to the target sound field are determined from the M sound-emitting units, and the driving units corresponding to the N sound-emitting units are controlled to drive the N sound-emitting units to vibrate and produce sound. Wherein, M is greater than or equal to N, and both M and N are positive integers.

[0064] The target sound may be audio data to be played by the electronic device, the target sound may be audio data acquired online in real time, or may be audio data cached by the electronic device.

[0065] After obtaining the sound-emitting unit of the electronic device for propagating sound in the area where the target object is located (target sound field), the driving unit corresponding to the sound-emitting unit is controlled to work so that the corresponding sound-emitting unit vibrates, thereby propagating the audio to be played in the target sound field. The intensity of the target sound heard by the target object in the target sound field is greater than the intensity of the target sound heard by other users outside the target sound field.

[0066] For example, user A uses a tablet computer to play music. The tablet computer uses a sound-gathering screen with multiple sound-emitting units. The tablet computer collects the profile information of user A. After obtaining the profile information of user A, the profile information of user A is analyzed to obtain the target sound field of the area where user A is located, and then multiple sound-emitting units that can propagate sound in the area where user A is located (target sound field) are determined. Then, by controlling the driving units corresponding to the obtained multiple sound-emitting units to work, the corresponding sound-emitting units vibrate, so that user A can clearly hear the music played by the tablet computer at his location. However, on the left and right sides or behind user A, other users cannot clearly hear the music played by the tablet computer.

[0067] It is understandable that by automatically adapting the number and position of the sound units according to the contour information of the target object, it can not only avoid the opening of redundant sound units and reduce energy consumption, but also enhance the directionality of the sound of the electronic device, effectively reduce the sound leakage problem on the left and right sides of the target object, and improve the user experience.

[0068] Figure 3 The second flowchart of the control method according to the embodiment of the present disclosure is schematically shown.

[0069] As described above, the electronic device includes a plurality of sound generating units. In operation S210, the sound generating unit of the electronic device corresponding to the target sound field is determined based on the contour information. Figure 3 As shown, the operation may further include operation S211a to operation S213a.

[0070] In operation S211a, a first parameter of the contour information is acquired, where the first parameter represents scale information of the target object in a first direction.

[0071] In operation S212a, a second parameter of the contour information is acquired, where the second parameter represents scale information of the target object in a second direction.

[0072] In operation S213a, a sound emission unit corresponding to the target sound field is determined according to the first parameter and / or the second parameter.

[0073] The first direction is perpendicular to the second direction.

[0074] Exemplarily, the first parameter may be the width of the entire target object, or the width of a target part of the target object. For example, the first parameter may be the width of the entire user A, or the width of the shoulders of user A, or the width between the two ears of user A.

[0075] The second parameter may be the overall height of the target object, or the height of a target part of the target object. For example, the second parameter may be the height of user A, or the second parameter may be the height of user A's ears.

[0076] The arrangement of multiple sound units of different devices may be different. For example, multiple sound units of some electronic devices are arranged in sequence along the width direction (first direction) of the electronic device. Multiple sound units of some electronic devices are arranged in sequence along the height direction (second direction) of the electronic device. Multiple sound units of some electronic devices are arranged in the form of multiple rows and columns along the width direction (first direction) and height direction (second direction) of the electronic device. Therefore, different parameters can be used to determine the position and number of sound units for multiple sound units with different arrangement methods.

[0077] In the case where multiple sound-emitting units of an electronic device are arranged in sequence along the width direction (first direction) of the electronic device, only the width (first parameter) of the target object in the first direction can be obtained, and the sound-emitting unit corresponding to the target sound field in the area where the target object is located can be determined according to the first parameter. In the case where multiple sound-emitting units of an electronic device are arranged in sequence along the height direction (second direction) of the electronic device, only the width (second parameter) of the target object in the second direction can be obtained, and the sound-emitting unit corresponding to the target sound field in the area where the target object is located can be determined according to the second parameter. In the case where multiple sound-emitting units of an electronic device are arranged in multiple rows and columns along the width direction (first direction) and the height direction (second direction) of the electronic device, respectively, the width (first parameter) of the target object in the first direction and the width (second parameter) of the target object in the second direction can be obtained respectively, and the sound-emitting unit corresponding to the target sound field in the area where the target object is located can be determined according to the first parameter and the second parameter. Here, the first direction of the target object is the same as the first direction of the electronic device, and the second direction of the target object is the same as the second direction of the electronic device. The first direction and the second direction can both be based on the length (first direction) and height (second direction) of the electronic device.

[0078] It should be noted that the embodiments of the present disclosure do not specifically limit the parameter information of the target object required for determining the sound unit in the target sound field corresponding to the target object, and can be adjusted according to the layout of the sound unit in the electronic device.

[0079] It can be understood that by determining the sound units required in different directions according to the scale information of the target object in multiple directions, the propagation of audio can be made more accurate.

[0080] As described above, in operation S213, a sound emission unit corresponding to the target sound field is determined according to the first parameter. In an achievable manner, the operation may further include the following operations:

[0081] A first quantity value of the sound emission units corresponding to the target sound field is determined according to the first parameter and the scale information of the sound emission units in the first direction.

[0082] A sound emission unit corresponding to the target sound field is determined according to the first quantity value and the position information, wherein the position information represents a relative position relationship between the target object and the sound emission unit.

[0083] Exemplarily, since the sound unit is integrated in the electronic device, the position information may be the distance and angle information between the target object and the electronic device. For example, the center of the plane where the display screen of the electronic device is located is used as the reference point, and the distance between the target object and the reference point is measured. The line perpendicular to the display screen of the electronic device is used as the reference line, and the angle between the target object and the reference line is measured.

[0084] In the process of determining the sound unit corresponding to the target sound field, when multiple sound units are arranged in sequence along the first direction of the electronic device, the first quantity value of the required sound units can be determined according to the width information of the target object in the first direction and the width information of each sound unit in the electronic device in the first direction. Then, according to the relative position relationship between the target object and the sound unit, the position of the sound unit of the first quantity value is determined. Finally, according to the calculated number of sound units (first quantity value) and the position of the sound unit (position information), the sound unit for the area where the target object is located (target sound field) is determined. And the required sound unit is controlled to vibrate and sound.

[0085] For example, the first quantity value may be a ratio of the width information of the target object in the first direction to the width information of each sound-emitting unit in the electronic device in the first direction. When the width of each sound-emitting unit in the first direction is the same, and when the widths of different users in the first direction are different, the first quantity values ​​are also different. Tables 1 and 2 schematically show the first quantity values ​​corresponding to different users.

[0086] Table 1

[0087]

[0088] Table 2

[0089]

[0090] When the first quantity value is a decimal, the first quantity value is determined according to the principle of rounding. For example, if the first quantity value corresponding to user A is 3.4, the corresponding number of required sound units is 3. If the first quantity value corresponding to user A is 3.7, the corresponding number of required sound units is 4.

[0091] In some other embodiments, when a plurality of sound-emitting units are sequentially arranged along the second direction of the electronic device, in operation S213, a sound-emitting unit corresponding to the target sound field is determined according to the second parameter. In one achievable manner, the operation may further include the following operations:

[0092] A second quantity value of the sound emission units corresponding to the target sound field is determined according to the second parameter and the scale information of the sound emission units in the second direction.

[0093] A sound emission unit corresponding to the target sound field is determined according to the second quantity value and the position information, wherein the position information represents a relative position relationship between the target object and the sound emission unit.

[0094] Exemplarily, the second quantity value may be the number of portions of the height information of the target object in the second direction that overlap with the height information of each sound-emitting unit in the electronic device. For example, when a plurality of sound-emitting units are sequentially arranged along the second direction of the electronic device, the plurality of sound-emitting units may be sequentially divided into a plurality of layers along the second direction. When the height of user A partially overlaps with the sound-emitting units of the first layer, the second layer, and the third layer, respectively, the second quantity value is three.

[0095] In the process of determining the sound unit corresponding to the target sound field, when multiple sound units are arranged in sequence along the second direction of the electronic device, the second number value of the required sound units can be determined based on the height information of the target object in the second direction and the height information of each sound unit in the electronic device. Then, based on the relative position relationship between the target object and the sound unit, the position of the sound unit of the second number value is determined. Finally, based on the calculated number of sound units (second number value) and the position of the sound unit (position information), the sound unit for the area where the target object is located (target sound field) is determined. And the required sound unit is controlled to vibrate and sound.

[0096] Figure 4A The third flowchart of the control method according to the embodiment of the present disclosure is schematically shown. Figure 4B One of the schematic diagrams of the control method according to the embodiment of the present disclosure is schematically shown.

[0097] As described above, in operation S213, a sound unit corresponding to the target sound field is determined according to the first parameter and / or the second parameter. Figure 4A , the operation may further include operation S2131~operation S2133.

[0098] In operation S2131, a first quantity value of the sound emission unit corresponding to the target sound field is determined according to the first parameter and the scale information of the sound emission unit in the first direction.

[0099] In operation S2132, a second quantity value of the sound emission unit corresponding to the target sound field is determined according to the second parameter and the scale information of the sound emission unit in the second direction.

[0100] In operation S2133, a sound emission unit corresponding to the target sound field is determined according to the first quantity value, the second quantity value, and the position information, where the position information represents a relative position relationship between the target object and the sound emission unit.

[0101] For example, refer to Figure 4B, when the electronic device has 8 sound units, and the 8 sound units are arranged in sequence along the first direction of the electronic device and along the second direction of the electronic device. Continuing to refer to Table 1, the first quantity value corresponding to user A is 3.4, then the number of sound units required by user A in the first direction is 3. The height of user A in the second direction is lower than the height of the first layer of sound units in the second direction, so it can only partially overlap with the sound units of the first layer. User A is facing the display screen at this time, then it can be determined that sound units 3, 4 and 5 are the required sound units (the sound units corresponding to the target sound field), and the driving units corresponding to sound units 3, 4 and 5 are controlled to drive sound units 3, 4 and 5 to vibrate, so that user A can hear the audio played by the electronic device at his position (target sound field).

[0102] Continuing to refer to Table 2, the first quantity value corresponding to user B is 5.3, so the number of sound units required by user B in the first direction is 5. The height of user B in the second direction is lower than the height of the first layer of sound units in the second direction, so it can only partially overlap with the sound units of the first layer. User B is facing the display screen at this time, so it can be determined that sound units 2, 3, 4, 5 and 6 are the required sound units (the sound units corresponding to the target sound field), and the driving units corresponding to sound units 2, 3, 4, 5 and 6 are controlled to drive sound units 2, 3, 4, 5 and 6 to vibrate, so that user B can hear the audio played by the electronic device at his position (target sound field).

[0103] The first quantity value corresponding to user C is 4.9, so the number of sound units required by user C in the first direction is 5. The height of user C in the second direction is higher than the height of the first layer of sound units in the second direction, and lower than the height of the second layer of sound units in the second direction, so it can partially overlap with the sound units of the first layer and the second layer. User C is facing the display screen at this time, so it can be determined that sound units 2, 3, 4, 5, 6 and 8 are the required sound units (the sound units corresponding to the target sound field), and the driving units corresponding to sound units 2, 3, 4, 5, 6 and 8 are controlled to drive sound units 2, 3, 4, 5, 6 and 8 to vibrate, so that user C can hear the audio played by the electronic device at his position (target sound field).

[0104] In other embodiments, when multiple sound units are of the same size and are arranged in multiple rows and columns in the first direction and the second direction, a first quantity value can be obtained based on the ratio of the width of the user to the width of a sound unit, and a second quantity value can be obtained based on the overlap between the height of the user and the height of each layer of sound units. The sound units of the first quantity value and the sound units of the second quantity value can form a rectangular frame, and according to the position of the target object, the rectangular frame can be used to select the sound units corresponding to the target sound field.

[0105] In some embodiments, the control method of this embodiment further includes: when the first quantity value is an odd number and the quantity is not less than 3, controlling the sound unit in the middle position to be turned off.

[0106] For example, continue to refer to Figure 4B , the first quantity value 3 of user A can determine that sound units 3, 4, and 5 are the sound units corresponding to the target sound field. At this time, only sound units 3 and 5 can be controlled to vibrate and make sounds, and sound unit 4 does not make sounds. In the process of sound units 3 and 5 vibrating and making sounds to propagate the target sound in the target sound field, since sound units 3 and 5 are symmetrically arranged with respect to sound unit 4, the audio received by user A can also be symmetrical with respect to the left and right ears, and the situation of inconsistent sound volume on the left and right sides is not allowed, so that the propagation of sound is more balanced.

[0107] The first quantity value corresponding to user B is 5.3, and it can be determined that sound units 2, 3, 4, 5, and 6 are the sound units corresponding to the target sound field. At this time, sound units 2, 3, 5, and 6 can be controlled to vibrate and make sounds, and sound unit 4 does not make sounds.

[0108] In some embodiments, when the environments on both sides of the target object generate noises of different intensities, the sound-emitting units on both sides of the silent unit may also be controlled to emit target sounds of different intensities.

[0109] Among them, the noise intensity is proportional to the intensity of the sound emitted by the sound unit.

[0110] For example, taking the user B as an example, the sound unit 4 does not make any sound. If the noise intensity on the left side of the user B is greater than the noise intensity on the right side, the sound units 2 and 3 can be controlled to make sounds at the first sound intensity, and the sound units 5 and 6 can be controlled to make sounds at the second sound intensity, and the first sound intensity is greater than the second sound intensity.

[0111] In other embodiments, each sound-emitting unit corresponding to the target sound field may be controlled to emit sound at different intensities. For example, taking the above user B as an example, sound-emitting unit 2, sound-emitting unit 3, sound-emitting unit 5, and sound-emitting unit 6 may be controlled to emit sound at different sound intensities.

[0112] Figure 5 A fourth flowchart of the control method according to an embodiment of the present disclosure is schematically shown.

[0113] As described above, in operation S210, in response to obtaining the contour information of the target object, in one possible implementation, Figure 5 As shown, the operation may further include operation S211b to operation S214b.

[0114] In operation S211b, in response to triggering the sound generation operation of the electronic device, a target image of a target area is acquired through an image acquisition device, where the target area includes at least a portion of a target sound field.

[0115] In operation S212b, it is determined whether the target image includes the target object.

[0116] In operation S213b, when the target image includes the target object, contour information of the target object is acquired by a positioning device.

[0117] In operation S214b, in a case where the target image does not include the target object, the sound generation is stopped.

[0118] The positioning device and the image acquisition device are the same or different.

[0119] Exemplarily, the target area may be an area where the sound unit of the electronic device can propagate. The target area may include an area where the target sound field and the non-target sound field are located. For example, the target area may include an area where the target object is located and areas on both sides of the target object.

[0120] The image acquisition device may be a camera.

[0121] The positioning device may be a device capable of capturing shape information of an object, for example, the positioning device may be a camera, a laser radar, an infrared sensor, etc.

[0122] For example, a user uses a music player app on a tablet computer to play a song. When the user clicks on the song to play, the image (target image) in front of the tablet computer (target area) can be captured by the front camera of the tablet computer, and the target image can be analyzed to determine whether the target image contains a target object. Here, the target object can be an object that can receive audio data, such as a person, an animal, or a plant. If the target image contains the target object, the contour information of the target object is obtained through the camera. If the target image does not contain the target object, the playback is stopped.

[0123] Figure 6 A fifth flowchart of the control method according to an embodiment of the present disclosure is schematically shown.

[0124] As described above, in operation S220, the driving unit of the electronic device is controlled to drive the sound unit to vibrate so that the sound unit outputs the target sound in the target sound field. Figure 6 As shown, the operation may further include operation S221 to operation S224.

[0125] In operation S221 , a target sound intensity of a target sound at the target object is obtained based on the position information of the target object.

[0126] In operation S222, it is determined whether the target sound intensity is lower than a first intensity threshold.

[0127] In operation S223, when the target sound intensity is lower than the first intensity threshold, the sound intensity of the target sound output by the sound emitting unit is adjusted to be not lower than the first intensity threshold.

[0128] In operation S224, when the target sound intensity is higher than the first intensity threshold, normal playback is performed.

[0129] For example, the target sound intensity may be the sound intensity heard at the location of the target object when the sound unit corresponding to the target sound field plays the audio data at the first volume. The target sound intensity may be calculated by receiving the target sound through an auxiliary device that is paired with the electronic device for communication.

[0130] The first intensity threshold may be the sound intensity required for the user to clearly hear the received audio data content at the user's location. The first intensity threshold required for users at different locations from the electronic device can be obtained in advance through testing. For example, when a general user is 50 cm away from the electronic device, the corresponding first intensity threshold is 70 dB. When the user is 60 cm away from the electronic device, the corresponding first intensity threshold is 80 dB. The farther the distance, the greater the first intensity threshold.

[0131] For example, when user A is 50 cm away from the electronic device, the sound unit 3, sound unit 4 and sound unit 5 of the electronic device play songs at the first volume, and the target sound intensity at user A is 50 dB. At this time, 50 dB is less than 70 dB, so the sound unit 3, sound unit 4 and sound unit 5 play songs at the second volume, so that the target sound intensity at the location of user A is greater than or equal to 70 dB, and the second volume is greater than the first volume. If the target sound intensity at user A is 80 dB, the song can continue to be played.

[0132] In some other embodiments, if the target sound intensity is greater than the second intensity threshold and the second intensity threshold is greater than the first intensity threshold, the sound intensity of the target sound output by the sound emitting unit is adjusted to be not less than the first intensity threshold and not more than the second intensity threshold.

[0133] For example, the second intensity threshold is 80 dB. If the target sound intensity at user A is 90 dB, and 90 dB is greater than 80 dB, the sound unit 3, the sound unit 4 and the sound unit 5 will play the song at the third volume so that the target sound intensity at the user A's location is greater than 70 dB and less than 90 dB.

[0134] Based on the above control method, the present disclosure also provides an electronic device. Figure 7-Figure 9 The electronic device is described in detail.

[0135] Figure 7 The structural diagram of an electronic device according to an embodiment of the present disclosure is schematically shown.

[0136] like Figure 7 As shown, the electronic device 200 of this embodiment includes: at least one sound-emitting unit 201 , at least one driving unit 202 , and a controller 203 .

[0137] The driving unit 202 corresponds to the sound generating unit 201 one by one, and the driving unit 202 is used to drive the sound generating unit 201 to vibrate.

[0138] The controller 203 is electrically connected to the driving unit 202. The controller 203 is used to determine the sound unit 201 of the electronic device 200 corresponding to the target sound field based on the contour information in response to obtaining the contour information of the target object, and control the driving unit 202 to drive the sound unit 201 to vibrate so that the sound unit outputs the target sound in the target sound field; wherein the intensity of the target sound in the target sound field is greater than the intensity of the target sound outside the target sound field, and the target sound field is an area including the target object.

[0139] Exemplarily, there may be one or more driving units and sound generating units. One driving unit drives one sound generating unit to vibrate and generate sound.

[0140] For an electronic device to control a driving unit through a controller to drive a sound generating unit to vibrate and generate sound, reference can be made to the above Figure 2A The description will not be repeated here.

[0141] Fig. 8A Schematically shows one of the layout diagrams of the sound generating units according to an embodiment of the present disclosure; Figure 8B The second schematic diagram of the arrangement of the sound-emitting unit according to the embodiment of the present disclosure is schematically shown; Figure 8C The third schematic diagram of the arrangement of the sound-emitting unit according to the embodiment of the present disclosure is schematically shown; Fig.8D A fourth schematic diagram of the arrangement of sound units according to an embodiment of the present disclosure is schematically shown.

[0142] In some embodiments, the electronic device includes: a first sound unit group and a second sound unit group arranged in sequence along a second direction.

[0143] The first sound unit group and the second sound unit group each include at least one sound unit; the first sound unit group and the second sound unit group have different scale information in the second direction; the first sound unit group and the second sound unit group have different numbers of sound units and / or scale information in the first direction.

[0144] Exemplarily, different electronic devices have different arrangements of sound units. For example, referring to FIG8A , the electronic device 200 includes a first sound unit group 201A and a second sound unit group 201B, and the first sound unit group 201A and the second sound unit group 201B are arranged in sequence along the height direction (second direction D2) of the electronic device 200. The first sound unit group 201A includes 7 sound units (sound units 1-7). The 7 sound units are arranged continuously along the first direction D1. The second sound unit group 201B includes 1 sound unit (sound unit 8). The length and height of the sound units of the first sound unit group 201A and the second sound unit group 201B are different.

[0145] Reference Figure 8B The electronic device 200 includes a first sound unit group 201A and a second sound unit group 201B, and the first sound unit group 201A and the second sound unit group 201B are arranged in sequence along the height direction (second direction D2) of the electronic device 200. The first sound unit group 201A includes 7 sound units (sound units 1-7). The 7 sound units are arranged continuously along the first direction D1. The second sound unit group 201B includes 2 sound units (sound unit 8). The 2 sound units are arranged at intervals along the first direction D1. The sound units of the first sound unit group 201A and the sound units of the second sound unit group 201B are different in length and height.

[0146] In other embodiments, referring to Figure 8C The electronic device 200 includes a first sound unit group 201A. The first sound unit group 201A includes 8 sound units (sound units 1-8). The 8 sound units are arranged continuously along a first direction D1.

[0147] It is understandable that the height of the sound unit in the first sound unit group 201A in the second direction is greater than the height of the sound unit in the second sound unit group 201B in the second direction, which can better adapt to the characteristics of the human body. It can ensure that the radiation range of the sound unit corresponding to the ear in the height direction is wider, so that the user's listening experience is better.

[0148] In other embodiments, reference Fig.8D The electronic device 200 includes a first sound unit group 201A and a second sound unit group 201B. The first sound unit group 201A includes 4 sound units, and the second sound unit group 201B includes 3 sound units. The sound units in the first sound unit group 201A and the second sound unit group 201B are arranged in multiple rows and columns (i.e., sound units 1-12). The sound units in the first sound unit group 201A and the second sound unit group 201B have the same length and height.

[0149] Fig. 9 The figure schematically shows a sound generating unit according to an embodiment of the present disclosure.

[0150] In some embodiments, when the contour information at least partially overlaps with the scale information of the second sound emission unit group in the second direction, the second sound emission unit group is controlled to output the target sound in the target sound field.

[0151] Exemplarily, in a case where the electronic device includes a first sound unit group 201A and a second sound unit group 201B, and the first sound unit group 201A and the second sound unit group 201B are arranged sequentially along the second direction D2, if the height of the target object in the second direction partially overlaps with the height of each layer of sound units in the second sound unit group 201B, all the sound units in the layer of sound units are controlled to output the target sound in the target sound field.

[0152] Reference Fig. 9, the height of user A in the second direction is lower than the height of the second sound unit group 201B in the second direction and there is no overlap. Then the sound unit 3, the sound unit 4 and the sound unit 5 are controlled to output the target sound in the target sound field, and the two sound units 8 in the second sound unit group 201B do not make a sound. The height of user C in the second direction partially overlaps with the height of the second sound unit group 201B in the second direction. Then the sound unit 2, the sound unit 3, the sound unit 5, the sound unit 6 and the two sound units 8 in the second sound unit group 201B are controlled to output the target sound in the target sound field.
