[0051] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0052] It should be noted that currently, electronic devices (such as speakers, etc.) are generally provided with a display screen to display relevant information. However, users will inevitably move when using them, which requires users to manually adjust the display screen to a better viewing position, resulting in a poor user experience.

[0053] Therefore, in order to solve the above-mentioned defects, the present embodiment provides a smart speaker, which may be provided with an image acquisition component and an adjustment component. When in use, the current imaging position of the center of the user's face in the image acquisition component can be obtained first, and the change angle can be determined according to the current imaging position and the preset standard imaging position. The inclination direction of the display screen is adjusted according to the change angle through the adjustment component, and the display screen is displayed through the adjusted display screen, so that the display screen can be placed in a position where the user has a better viewing effect in real time without the need for manual adjustment by the user, thereby improving the user experience.

[0054] For ease of understanding, the following combination Figure 1 and Figure 2 The smart speaker provided in the embodiment of the present application is introduced in detail.

[0055] Reference Figure 1 , Figure 1 A schematic diagram of the smart speaker structure of the hardware operating environment involved in the embodiment of the present application.

[0056] like Figure 1 As shown, the smart speaker includes: the smart speaker includes: a device body, an image acquisition component, an adjustment component, a display screen, a processor (not shown in the figure) and a memory (not shown in the figure), the display screen is rotatably connected to the device body through the adjustment component, and the processor, the memory and the image acquisition component can be respectively arranged on the device body or the display screen.

[0057] It should be noted that the smart speaker can be any smart speaker with a display screen, and the device body can be the speaker body of the smart speaker. The adjustment component can be a component for rotating the display screen and the speaker body, such as Figure 1 As shown, one end of the adjustment component in this embodiment can be set on the speaker body, and the end away from the speaker can be connected to the display screen. The display screen can be rotated relative to the speaker body through the adjustment component to adjust it to a better viewing angle for the user. Since this embodiment automatically adjusts the display screen, the above-mentioned adjustment component can be an adjustment component with a motor, and the rotation of the motor is controlled to control the rotation of the display screen relative to the speaker body. The specific implementation method of the adjustment component is not limited in this embodiment, and this embodiment uses a motor for illustration.

[0058] It is understandable that the above-mentioned image acquisition component can be a component for acquiring the user's face, such as an image sensor, etc. This embodiment is not limited to this. This embodiment uses a camera with an image sensor for illustration.

[0059] It should be understood that in this embodiment, the processor may be a central processing unit (CPU) and the memory may be a high-speed random access memory (RAM) or a stable memory (NVM), such as a disk memory. The memory may also be a storage device independent of the processor.

[0060] Furthermore, the processor and memory in this embodiment can be disposed in the display screen or in the speaker body, or one of them can be disposed in the display screen and the other in the speaker body. As for the image acquisition component, it can be disposed on the display screen or on the speaker body, and it only needs to ensure that the user's face can be acquired. Figure 1 As shown, this embodiment is described by arranging the image acquisition component on the display screen, and can be arranged on the top of the display screen, but this is not limited.

[0061] In order to realize the relevant functions of the speaker, refer to Figure 2 , Figure 2 This is an internal block diagram of the smart speaker of the present application embodiment, such as Figure 2 As shown, in this embodiment, the above-mentioned processor is connected to the image acquisition component, the display screen, the adjustment component and the memory respectively.

[0062] The image acquisition component is used to acquire the current imaging position of the center of the user's face and transmit the current imaging position to the processor;

[0063] The processor is used to run the display program stored in the memory, and when the display program is executed by the processor, the display method provided in the embodiment of the present application is implemented.

[0064] It should be understood that if Figure 2 As shown, the smart speaker in this embodiment may also include: a microphone, a speaker, a crystal and a wireless module, and the microphone, the speaker, the crystal and the wireless module are all connected to the processor;

[0065] The microphone may be a microphone array (i.e. Figure 2 MIC array in the middle), which can be used for voice recognition and wake-up sound collection; the above-mentioned speaker can be a stereo speaker (i.e. Figure 2 The above crystal can provide a stable clock source for the processor when it is working; the above wireless module (i.e. Figure 2 The WIFI / BT Module may be a module for wireless communication, including but not limited to wireless network and Bluetooth modules. The specific settings may be made according to the actual situation. This embodiment does not limit this and can be used for networking and wireless transmission.

[0066] It should also be understood that the microphone, speaker, crystal and wireless module mentioned above can be respectively disposed in the display screen or the speaker body, and this embodiment does not impose any limitation on this.

[0067] It should be emphasized that those skilled in the art can understand that Figure 1 and Figure 2 The structure shown in the figure does not constitute a limitation on the above-mentioned device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0068] In order to solve the above defects, the embodiment of the present application also provides a display method, which can be applied to the above smart speaker. For ease of understanding, the following is combined with Figures 3 to 7 The display method provided in the embodiment of the present application is introduced in detail.

[0069] Reference Figure 3 , Figure 3 The flowchart of the first embodiment of the display method of the present application is shown in FIG. Figure 3 As shown, in this embodiment, the method includes:

[0070] Step S10: Acquire the current imaging position of the user's face center in the image acquisition component.

[0071] It should be noted that the method of this embodiment can be applied to the scene where the display screen on the smart speaker is displayed, and of course it can also be applied to the scene where the display screen on other smart speakers is displayed, and this embodiment does not limit this. The execution subject of this embodiment can be a smart speaker with display, data processing, network communication and program running functions, such as the above-mentioned smart speaker, etc. This embodiment is explained with the above-mentioned smart speaker (hereinafter referred to as the device). Specifically, the specific structure of the above-mentioned device in this embodiment can be Figure 1 as well as Figure 2 The form shown, of course, can also be other forms, this embodiment adopts Figure 1 as well as Figure 2 Furthermore, the execution subject of the method of this embodiment may specifically be a processor in the above-mentioned device.

[0072] It is understandable that the face center of the above-mentioned user can be the center position of the user's face. In this embodiment, the face center can be defined as the best position for the user to view the display screen, that is, the position between the two eyes. Of course, it can also be other positions, and this embodiment does not limit this.

[0073] It should be understood that the current imaging position may be the imaging position of the face center on the image acquisition component. The image acquisition component may acquire the external environment and use the acquired middle position of the user's eyes as the face center position of the user. The camera in this embodiment may acquire the eye center position of the user and form an optical image on the image sensor, and the position of the optical image is the current imaging position of the face center of the user in the image acquisition component.

[0074] For ease of understanding, refer to Figure 4 To explain, Figure 4 This is a schematic diagram of facial center imaging in the first embodiment of the display method of this application, such as Figure 4 As shown, since the image sensor of the camera is located inside the display screen, if P2 is the center position of the user's face, then the position of the optical imaging of the center position of the face by the image sensor can be recorded as Figure 4 The position of P2' in the figure is taken as P2' as the current imaging position.

[0075] Step S20: determining the change angle of the face center according to the current imaging position and a preset standard imaging position.

[0076] It should be noted that the above-mentioned preset standard imaging position may be a position where the user has a better viewing experience in the optical imaging of the image acquisition component. Figure 4The position P1 in the figure is a better viewing position, and the position of the optical imaging of this position on the image sensor can be recorded as P1', and then the position P1' can be used as the above-mentioned preset standard imaging position.

[0077] It should be emphasized that due to the different heights, viewing habits, etc. of different users, the above-mentioned preset standard imaging position can be obtained by custom settings according to different users in advance, that is, a registration process is performed before use to make the display screen at an angle suitable for the user, and the imaging position of the image sensor for the center of the user's face at this angle is used as the preset standard imaging position of the user. Of course, the above-mentioned preset standard imaging position can also be set in other ways, and this embodiment is not limited to this.

[0078] The above-mentioned change angle can be the angle between the current imaging position of the center of the user's face and the preset standard imaging position. Figure 4 , when the user's face center changes from P1 to P2, the corresponding optical imaging position of the image sensor will also change from P1' to P2'. If point H is the center position of the image sensor imaging, the perpendicular bisector of the image sensor (i.e. Figure 4 The intersection of OP1' and the display screen is denoted as O, and OH is perpendicular to the imaging surface of the image sensor. The angle between OP1' and OH is denoted as θ1, and the angle between OP2' and OH is denoted as θ2. It can be explained that the angle changes from θ1 to θ2, and the difference between θ1 and θ2 can be used as the change angle of the center of the face.

[0079] Step S30: adjusting the tilting direction of the display screen according to the change angle by the adjusting component, and performing display by the adjusted display screen.

[0080] It is understandable that after the processor determines the change angle, it can control the adjustment component according to the change angle so that the adjustment component adjusts the tilt of the display screen. Specifically, the current imaging position of the image sensor on the adjusted display screen to the center of the face can be located at the P1' position, which means that the display screen is adjusted to a position where the user can see better, and then the display screen can be used for display. Therefore, the user does not need to make manual adjustments, which improves the user experience.

[0081] As another implementation method, when the image acquisition component is not arranged on the display screen but on the speaker body, a preset mapping relationship can be set in advance. The preset mapping relationship can store the adjustment direction of the display screen corresponding to different change angles. Therefore, in actual use, after determining the change angle, the preset mapping relationship can be queried to control the adjustment component for adjustment.

[0082] Furthermore, in order to set corresponding preset standard imaging positions according to different user settings, in this embodiment, before the above step S10, it also includes:

[0083] Step S01: searching the external environment through the image acquisition component, and determining the center position of the user's face according to the search results;

[0084] Step S02: adjusting the display screen based on the face center position to obtain a preset standard imaging position.

[0085] In actual use, the processor can first control the image sensor to search the external environment in which the device is located. In order to make the search results more comprehensive, the adjustment component can be controlled at the same time to drive the display screen to rotate, so that the image sensor can capture a wider external environment; and analyze whether the user's face center exists in the search results obtained; if not, the user is prompted to put the face center into the search range, or the user is prompted to turn the speaker body, or enter a sleep state; if it exists, the user's face center position is determined according to the search results and the adjustment component is controlled to adjust the display screen. If the user feels that the display screen can be clearly seen at this angle, the processor can control the adjustment component to stop rotating by pressing buttons or voice, and then the processor can use the image sensor at this angle The imaging position of the user's face center is used as the above-mentioned preset standard imaging position to complete the entry.

[0086] As another implementation method, the image sensor can also capture the entire facial image of the user and determine whether the facial image is in the middle position of the display screen; if not, continue to control the adjustment component to drive the display screen to rotate; if so, use the imaging position of the image sensor at this angle for the center of the user's face as the above-mentioned preset standard imaging position to complete the entry.

[0087] Furthermore, in order to facilitate the adjustment of the display screen during recording, in this embodiment, the above-mentioned smart speaker can also be provided with an angle collection component, such as Figure 2 As shown, the angle acquisition component can be any component for acquiring angles. This embodiment uses an angle sensor for illustration. The angle sensor can be connected to a processor. In this embodiment, the angle sensor can be used to measure the tilt angle of a display screen, and the angle sensor can be set in the display screen. And because the display screen can be adjusted in this embodiment, horizontal adjustment and tilt adjustment can be involved, and the number of the above-mentioned angle sensors can be set to at least two, one of which is used to measure the horizontal angle of the display screen, and the other is used to measure the tilt angle of the display screen.

[0088] Furthermore, before the step of searching the external environment by the image acquisition component, the method further includes:

[0089] When power-on is detected, the angle of the tilt direction of the display screen is acquired through the angle acquisition component; when the acquisition result is inconsistent with the initial default tilt direction, the tilt direction of the display screen is adjusted to the initial default tilt direction through the adjustment component, and the step of searching the external environment through the image acquisition component is executed.

[0090] It should be noted that the above-mentioned initial default tilt position can be a preset tilt position of the display screen that makes the center position of the face be in a preset standard imaging position. In actual use, since the display screen is not in the position when the user is initially powered on after use, the preset standard imaging position cannot be accurately determined when the user uses it next time.

[0091] Furthermore, in this embodiment, each time the device is powered on, the tilt position of the display screen can be detected by the angle sensor to obtain a horizontal angle and a tilt angle as the above acquisition result. It is also determined whether the horizontal angle and the tilt angle are consistent with the angles corresponding to the preset initial default tilt position; if they are inconsistent, the adjustment component can be controlled to adjust the display screen to the initial default tilt position, and after the adjustment, the image sensor can be used to search; if they are consistent, the search can be started directly.

[0092] This embodiment may be provided with an image acquisition component and an adjustment component. When in use, the current imaging position of the center of the user's face in the image acquisition component can be obtained first, and the change angle can be determined according to the current imaging position and the preset standard imaging position. The inclination of the display screen can then be adjusted according to the change angle through the adjustment component, and the adjusted display screen can be used for display, so that the display screen can be placed in a position where the user has a better viewing effect in real time without the need for manual adjustment by the user, thereby improving the user experience.

[0093] Reference Figure 5 , Figure 5 This is a flow chart of the second embodiment of the display method of the present application. Based on the above-mentioned first embodiment, the second embodiment of the display method of the present application is proposed.

[0094] In order to accurately determine the change angle of the face center, so as to facilitate the subsequent control and adjustment of the adjustment components, such as Figure 5 As shown, in this embodiment, before the above step S10, it also includes:

[0095] Step S03: determining a preset standard imaging angle between a preset standard imaging position and the optical center of the image acquisition component.

[0096] Continue to combine Figure 4 For illustration, the optical center of the above-mentioned image acquisition component can be the center of the optical imaging surface of the image acquisition component, that is, Figure 4The above-mentioned preset standard imaging angle can be the preset standard imaging position and the position of the optical center on the display screen (ie Figure 4 The angle between the line connecting the optical center and the position of the optical center on the display screen, that is, Figure 4 Before use, the processor can determine the preset standard imaging angle according to the preset standard imaging position, the optical center of the image acquisition component and the position of the optical center on the display screen.

[0097] The above step S20 includes:

[0098] Step S21: determining a current imaging angle between the optical center and the current imaging position;

[0099] Step S22: determining a change angle of the face center based on the current imaging angle and the preset standard imaging angle.

[0100] It should be noted that the current imaging angle may be the angle between the line connecting the current imaging position and the position of the optical center on the display screen and the line connecting the optical center and the position of the optical center on the display screen, that is, Figure 4 Medium θ2.

[0101] After obtaining the current imaging position, the current imaging angle θ2 can be determined according to the current imaging position, and the above-mentioned change angle can be determined according to the preset standard imaging angle θ1 and the current imaging angle θ2. If the change angle is recorded as △θ, then △θ=|θ1-θ2|. The absolute value is used because θ1 may be less than θ2.

[0102] Further, considering that the display screen may be adjusted in a horizontal direction and in a pitch direction, the horizontal adjustment may be that the adjustment component controls the display screen to deflect in a horizontal direction, such as to the left or right, and the pitch adjustment may be that the adjustment component controls the display screen to deflect in a pitch direction, such as to deflect upward or downward, so as to adjust the display screen more accurately and further improve the adjustment effect, in this embodiment, the above step S21 includes:

[0103] Step S211: determining a preset standard imaging horizontal angle and a preset standard imaging pitch angle between a standard imaging position and the optical center of the image acquisition component.

[0104] It is understandable that the above-mentioned preset standard imaging horizontal angle may be the angle in the horizontal direction corresponding to the preset standard imaging position, and the above-mentioned preset standard imaging pitch angle may be the angle in the pitch direction corresponding to the preset standard imaging position. Figure 4 and Figure 6 , Figure 6This is a schematic diagram of facial center imaging in the second embodiment of the display method of this application. Figure 4 Defined as the facial center imaging diagram in the pitch direction, Figure 6 Defined as a schematic diagram of the facial center imaging in the horizontal direction, Figure 4 P1' in the figure can be the position point of the preset standard imaging position in the pitch direction. Figure 6 The "P1" in the figure may be the position point of the preset standard imaging position in the horizontal direction.

[0105] It should be emphasized that, in this embodiment, for the horizontal direction, the horizontal position of the preset standard imaging position is set at the optical center. Figure 6 In the example, P1" coincides with H. Then Figure 4 Where θ1 is the above preset standard imaging pitch angle, Figure 6 The angle θ1' between OP1" and OH is 0°.

[0106] In order to determine the preset standard imaging horizontal angle and the preset standard imaging pitch angle, in this embodiment, the step S211 includes:

[0107] Determine the vertical distance between the display panel of the display screen and the optical center of the image acquisition component, and determine the standard horizontal distance and the standard pitch distance between the optical center and the standard imaging position;

[0108] A preset standard imaging horizontal angle between the standard imaging position and the optical center is determined according to the standard horizontal distance and the vertical distance, and a preset standard imaging pitch angle between the standard imaging position and the optical center is determined according to the standard pitch distance and the vertical distance.

[0109] It should be understood that the vertical distance may be the distance between the optical center (i.e., point H in the figure) and the position of the optical center on the display panel of the display screen (i.e., point O in the figure), i.e., OH, denoted as h; the standard horizontal distance may be the horizontal position point of the preset standard imaging position (i.e., Figure 6 The distance between the point P1" in the center and the optical center, that is, P1"H; the above-mentioned standard pitch distance can be the pitch position point of the preset standard imaging position (that is, Figure 4 The distance between the point P1' in the center and the optical center is P1'H.

[0110] After obtaining the vertical distance OH, the standard horizontal distance P1”H and the standard pitch distance P1'H, the preset standard imaging horizontal angle can be obtained through trigonometric functions based on the vertical distance OH and the standard horizontal distance P1”H, that is, tanθ1'=P1”H / OH; the preset standard imaging pitch angle can be obtained through trigonometric functions based on the vertical distance OH and the standard pitch distance P1'H, that is, tanθ1=P1'H / OH.

[0111] The above step S22 includes:

[0112] Step S221: determining a current imaging horizontal angle and a current imaging pitch angle based on the current imaging angle;

[0113] Step S222: determining the horizontal change angle of the face center according to the current imaging horizontal angle and the preset standard imaging horizontal angle, and determining the pitch change angle of the face center according to the current imaging pitch angle and the preset standard imaging pitch angle.

[0114] It should be noted that the current imaging horizontal angle may be the angle in the horizontal direction corresponding to the current imaging position, and the current imaging pitch angle may be the angle in the pitch direction corresponding to the current imaging position. Figure 4 Where P2' can be the position point of the current imaging position in the pitch direction, Figure 6 P2" in the figure can be the position point of the current imaging position in the horizontal direction.

[0115] based on Figure 4 and Figure 6 , then the above-mentioned current imaging horizontal angle can be the angle between OP2" and OH, which can be recorded as θ2', and the above-mentioned current imaging pitch angle can be the angle between OP2' and OH, which can be recorded as θ2.

[0116] The horizontal change angle may be a change angle in the horizontal direction, and the pitch change angle may be a change angle in the pitch direction. After determining the current imaging horizontal angle and the current imaging pitch angle, the horizontal change angle of the face center may be determined according to the current imaging horizontal angle θ2' and the preset standard imaging horizontal angle θ1', and the pitch change angle of the face center may be determined according to the current imaging pitch angle θ2 and the preset standard imaging pitch angle θ1. If the horizontal change angle is recorded as △θ, then △θ=|θ1-θ2|, and if the pitch change angle is recorded as △θ', then △θ'=|θ1'-θ2'|.

[0117] The step of adjusting the tilting position of the display screen according to the changing angle by the adjusting component comprises:

[0118] Step S31: adjusting the tilting direction of the display screen according to the horizontal variation angle and the pitch variation angle by the adjusting component.

[0119] After the horizontal change angle △θ and the pitch change angle △θ' are determined, the adjustment component can be controlled to adjust according to the horizontal change angle △θ and the pitch change angle △θ'. Adjusting them to 0 respectively indicates that they have been adjusted to a better viewing position for the user.

[0120] Furthermore, considering that the horizontal adjustment includes leftward and rightward, and the pitch adjustment includes upward and downward, in order to accurately determine the adjustment direction, in this embodiment, the step of adjusting the tilt azimuth of the display screen according to the change angle by the adjustment component includes:

[0121] An adjustment direction is determined according to the change angle; and the tilting direction of the display screen is adjusted according to the adjustment direction and the change angle by the adjustment component.

[0122] Specifically, the processor in this embodiment may determine the adjustment direction according to the sign of the change angle that does not contain an absolute value.

[0123] For example, for the pitch direction, if the sign of θ1-θ2 is negative, that is, θ1<θ2, it can be explained that the display screen needs to be controlled to rotate counterclockwise in the pitch direction until θ1=θ2; if the sign of θ1-θ2 is positive, that is, θ1 is greater than θ2, it can be explained that the display screen needs to be controlled to rotate clockwise in the pitch direction until θ1=θ2;

[0124] For the horizontal direction, the relative position between the current imaging position and the preset standard imaging position can be determined according to the change angle, and the adjustment direction can be determined according to the relative position. Specifically, if the current imaging position is located to the left of the preset standard imaging position, it means that the display screen needs to be controlled to deflect clockwise in the horizontal direction until θ1'=θ2'; if the current imaging position is located to the right of the preset standard imaging position, it means that the display screen needs to be controlled to deflect counterclockwise in the horizontal direction until θ1'=θ2'.

When in use, the current imaging position of the center of the user's face in the image acquisition component can be obtained first, and the change angle can be determined according to the current imaging position and the preset standard imaging position.
