Similarly, the phrase "if determined" or "if [described condition or event] is detected" may be interpreted, depending on the context, as "once determined," "in response to determination," "once [described condition or event] is detected," or "in response to detection of [described condition or event]."

[0030] The specific embodiments disclosed herein will now be described in detail with reference to the accompanying drawings.

[0031] This disclosure provides a handheld learning device, which can be a dictionary pen, a listening and speaking aid, a repeater, or a learning machine, etc., and is used to realize the basic functions of such devices. The following examples will detail the content of this solution.

[0032] like Figure 1a and Figure 1b As shown, this disclosure provides a handheld learning device 100, which includes a cuboid-shaped main body containing a control board responsible for handling the operation and functions of the device. At one end of the handheld learning device 100 main body along its length, a mounting end 113 and a support portion 109 are specifically designed; these two components together constitute the scanning mechanism of the handheld learning device 100.

[0033] Specifically, the mounting end 113 has an inclined end face, on which at least the first scanning assembly 111 in communication connection with the control board is mounted. Connected to the mounting end 113 is the supporting part 109, one end of which is connected to the mounting end 113, and the other end extends away from the mounting end along the length direction and is in contact with the object to be scanned, playing a role of stabilization and support. In addition, the supporting part 109 is provided with a scanning window, which is aligned with the text by the user during use, so that the first scanning assembly 111 can capture the text information and process it.

[0034] When the handheld learning machine 100 in the present scheme is in a vertical state, the end face at the mounting end is not horizontally arranged but is arranged to be inclined, and the first scanning assembly 111 is provided with a mounting seat, which is vertically mounted on the inclined end face, so that the first scanning assembly 111 is also arranged to be inclined and has an included angle with the horizontal plane. The purpose of such arrangement is to optimize the scanning angle, make it more in line with the user's usage habits, improve the convenience and accuracy of scanning, and improve the scanning efficiency.

[0035] In a specific embodiment, the first scanning assembly 111 includes a first camera 111-1 and two first light supplementing lamps 111-2. The first camera 111-1 is used to scan the image of the object to be scanned (such as text), so that the handheld learning machine can further process and recognize. And the first light supplementing lamp 111-2 is used in cooperation with the first camera 111-1 to provide additional light during scanning, so as to ensure that the camera can capture a clear and easily recognizable image.

[0036] In a specific embodiment, the included angle between the extension of the inclined end face to the horizontal direction and the horizontal plane is 0-36 degrees. Such design means that the included angle between the first scanning assembly 111 arranged on the end face and the horizontal plane is also 0-36 degrees. Those skilled in the art can understand that such an inclined angle is arranged to make it more convenient for the user to align the object to be scanned during scanning.

[0037] Compared with the conventional arrangement that the end face of the mounting end 113 is parallel to the object to be scanned, the inclined end face makes the first scanning assembly 111 more tend to be directly opposite to the object to be scanned during use. Such design not only improves the user's comfort, but also enables the scanning assembly to be more directly aligned with the text, thereby realizing a larger scanning range. Therefore, such inclined end face design not only improves the user experience, but also improves the scanning efficiency and range of the handheld learning machine.

[0038] In one specific embodiment, when the body of the handheld learning machine 100 is in the vertical state, the vertical distance between the center of the first scanning assembly 111 and the plane where one end of the support portion 109 away from the mounting end 113 is 15-35 mm. That is, the height of the first scanning assembly 111 in this scheme is 15-35 mm. The height range provided by this scheme helps to select a larger FOV (camera field of view), which can expand the scanning range. In addition, the height range in this scheme can reduce the interference of finger or device shadow on the scanning result, and improve the accuracy of scanning.

[0039] The above scheme describes the mounting end and the first scanning assembly 111 in detail, and the structure of the support portion 109 is described in detail next.

[0040] In one specific embodiment, the support portion 109 includes a first support portion 1091 and two symmetrically arranged second support portions 1092. Specifically, the body includes a shell, which includes oppositely arranged front and rear side walls 101 and 102, and left and right side walls 103 and 103-1 connected to the front and rear side walls 101 and 102, respectively. The shell can be manufactured by one-piece molding, which directly forms a complete shell structure through a single material or mold, ensuring the strength and integrity of the shell. On the other hand, the shell can also be assembled by individual side walls. This modular design allows more flexible manufacturing and assembly process. For example, the left and right side walls can be arranged on the front or rear side walls, respectively, and the shell can be formed by abutting. This design makes the connection of each side wall more flexible, facilitating assembly and maintenance. In addition, the front and rear side walls can be designed with extension sections at both ends in the width direction, which can abut each other to form the left and right side walls. That is, the division of each side wall in this scheme is defined with respect to the formed body, rather than according to the manufacturing process.

[0041] One end of the first support portion 1091 is connected to the front side wall 101 of the body at the mounting end 113, and the other end is first extended away from the mounting end 113 along the length direction, and then extended to the extension surface of the rear side wall 102 of the body. One end of one of the second support portions 1092 is connected to the left side wall 103 of the body at the mounting end 113, and the other end is first extended away from the mounting end 113 along the length direction, and then extended perpendicularly to the extension surface of the right side wall 103-1. The other end of the other second support portion 1092 is connected to the right side wall 103-1 of the body at the mounting end 113, and the other end is first extended away from the mounting end 113 along the length direction, and then extended perpendicularly to the extension surface of the left side wall 103.

[0042] More specifically, the extended end of the first support portion 1091, the extended ends of the two second support portions 1092, and the rear side wall 102 of the body at the mounting end 113 enclose the scanning window. The handheld learning machine 100 provided by the present solution is also provided with a pressure-sensitive component in communication with the control board, which can be arranged only on the first support portion 1091, or arranged on both the first support portion 1091 and the second support portion 1092. Of course, those skilled in the art can understand that the pressure-sensitive component can also be arranged at other positions according to actual conditions.

[0043] It is worth noting that the first support portion 1091 in the present solution has two extension sections, one of which extends along the length direction of the body, and the other of which extends along the thickness direction of the body, and the connection between the two extension sections is a smooth arc. The second support portion 1092 also has two extension sections, one of which extends along the length direction of the body, and the other of which extends along the width direction of the body, and the connection between the two extension sections is also a smooth arc.

[0044] In another specific embodiment, the scanning window of the handheld learning machine 100 is enclosed by several specific components, specifically including the extended end of the first support portion 1091, the extended ends of the two second support portions 1092, and the extended end of the rear side wall 102 of the body at the mounting end 113. One end of the extension section on the body is connected to the rear side wall 102, and the other end extends away from the mounting end 113 along the length direction.

[0045] Specifically, the rear side wall 102 of the body at the mounting end 113 is provided with an extension section, and the end of the extension section together with the ends of the first support portion 1091 and the two second support portions 1092 constitutes the boundary of the scanning window. Such a design enables the extension section of the rear side wall 102 to shield the first scanning component 111, thereby providing physical protection for the first scanning component 111. This protection mechanism can effectively prevent the first scanning component 111 from being scratched or damaged in daily use, ensuring the stability of the scanning window and the safety of the camera module.

[0046] It is worth noting that in the present solution, the scanning window is designed to have a predetermined width, specifically in the range of 28mm to 43mm. This width refers to the extension direction of the left side wall 103 to the right side wall 103-1 of the body, i.e., the scanning window expands along the width direction of the handheld learning machine 100. In addition, the two ends of the scanning window in the width direction are designed to be arc-shaped. That is, the ends of the two second support portions 1092 are arranged in a bracket-like structure. This design not only provides a clear scanning area, but also helps to reduce the discomfort that the edges of the scanning window may cause to the user, while also increasing the aesthetic appeal.

[0047] In one specific implementation, to avoid the end of the first support portion 1091 obstructing the first scanning component 111, the position and shape of the first support portion 1091 are specifically designed. Specifically, when the handheld learning machine 100 is in a vertical position, the extended end of the first support portion 1091 is designed not to exceed the projection of the first scanning component 111 onto the horizontal plane. This design logic ensures that the first scanning component 111 is not interfered with by the end of the first support portion 1091 during scanning operations, thereby guaranteeing a smooth scanning process and accurate scanning results.

[0048] Those skilled in the art will understand that the extension length of the first support portion 1091 is designed to be greater than the extension length of the rear sidewall 102. When the handheld learning machine 100 is in a vertical position, the end face closer to the object to be scanned at vertical distance is connected to the front sidewall 101, and the end face farther from the object to be scanned at vertical distance is connected to the rear sidewall 102. That is, in this design, the length of the front sidewall 101 is greater than the length of the rear sidewall 102, one end of the mounting end 113 is connected to the rear sidewall 102, and the other end is connected to the front sidewall 101. This design, by limiting the tilt direction of the end face, enables the first scanning component 111 to perform scanning operations more effectively.

[0049] In some specific implementations, those skilled in the art will understand that the support portion can be integrally formed with the housing or can be assembled from independent components. When the support portion is integrally formed with the housing, the first support portion is formed by extending downward from the end of the front sidewall, and the two second support portions are formed by extending downward from the ends of the left sidewall and the right sidewall.

[0050] When the support and housing are not integrally formed, they are several independently configured components, which are then fixed together by adhesive or other means. In this case, to prevent the extensions of the support 109 and the rear sidewall 102 from obstructing the content to be scanned, this solution uses a transparent material to fabricate the support 109 and the extensions of the rear sidewall 102. For example, the transparent material can be glass, plastic, etc.

[0051] In some embodiments, the handheld learning machine 100 in the present scheme has a larger scanning range due to the design form of the end surface and the setting position and height of the first scanning assembly 111. Specifically, when the body of the handheld learning machine 100 is in a vertical state, since the first scanning assembly 111 is arranged on the inclined end surface, the first scanning assembly 111 has a preset range of scanning interval in the direction towards the rear wall 102. Specifically, the scanning length range of the scanning interval is set to be between 25mm to 80mm, and the scanning width range of the scanning interval is between 35mm to 80mm. This design allows the handheld learning machine 100 to cover a wide range of text areas in different directions. In the present scheme, the direction of the scanning length is along the extension direction of the front wall 101 to the rear wall 102 of the body of the handheld learning machine 100, which means that the user can scan longer text lines in this direction. While the extension direction of the scanning width is from the left wall 103 to the right wall 103-1 of the body, which allows the user to cover a wider text area in width. Such a scanning range setting ensures the efficiency and applicability of the handheld learning machine 100 in actual use.

[0052] Of course, those skilled in the art can understand that the scanning interval range of the first scanning assembly 111 in the handheld learning machine is determined by two key factors: one is the inclination angle range of the first scanning assembly 111, and the other is the distance range between the first scanning assembly 111 and the end of the first support part 1091. This design takes into account the inclination of the scanning assembly on the end surface and its relative position with the support structure, thereby ensuring the flexibility and adaptability of the scanning interval. The present scheme carefully designs the distance between the first scanning assembly 111 and the support part 109, as well as the inclination angle of the first scanning assembly 111, so that the handheld learning machine 100 can achieve a wide and flexible scanning interval. This not only improves the accuracy and efficiency of scanning, but also enables the handheld learning machine 100 to meet diverse scanning needs, enhancing its competitiveness in the market.

[0053] It is worth noting that the structure of the support part is not limited to the shape described in the present scheme, and it can have many different design forms. For example, the support part can be as shown in Figure 4 and Figure 5 , specifically including four peripheral walls, and the extension length of the front peripheral wall is greater than that of the rear peripheral wall. That is, in other schemes, the support part can adopt other shapes and structures according to specific application needs and design requirements to adapt to different use scenarios and functional requirements. These different structural designs, although different in appearance and structure from the support part described in the present scheme, still have the core purpose of cooperating with the end surface of the mounting end and the first scanning assembly to achieve the effect of increasing the scanning range.

[0054] As Figure 2a - Figure 2c As shown in the specific embodiment, the first scanning component is a fisheye camera. Those skilled in the art can understand that, due to the unique profile of the fisheye camera, the mounting seat of the fisheye camera is a shell 119 covering the outer periphery of the fisheye camera, which is inserted into the mounting groove on the mounting end for fixation. Since the end face of the mounting end in this scheme is inclined, the fixed end of the shell is fixed perpendicular to the inclined end face. When the handheld learning machine is in the vertical state, an included angle will be formed between the fisheye camera and the horizontal line, and the included angle is 0 to 15 degrees. That is, the included angle between the extension of the end face of the mounting end and the horizontal plane in this embodiment is also 0 to 15 degrees.

[0055] In a specific embodiment, in order to further improve the scanning range of the handheld learning machine 100, a second scanning component 114 in communication connection with the control board is further provided on the end face of the mounting end 113 of the handheld learning machine 100, and the second scanning component 114 is spaced apart from the first scanning component 111. That is, the handheld learning machine 100 provided in this scheme is provided with two scanning components, which can scan more content. In order to adapt to the two scanning components, a processing module is further provided on the control board in this scheme, which functions to sort the content scanned by the first scanning component 111 and the second scanning component 114, for example, deleting the repeated content and integrating the remaining content.

[0056] In a specific embodiment, the second scanning component 114 is also mounted on the inclined end face of one end of the body length direction, and an installation seat is provided thereon, which is fixed vertically on the end face, so that the second scanning component 114 is also inclined. Specifically, the second scanning component 114 includes two parts, namely a second camera 114-1 and a second light supplementing lamp 114-2. Such design enables the second scanning component 114 to work cooperatively with the first scanning component 111, improving the scanning efficiency and accuracy.

[0057] It is particularly worth mentioning that the first camera 111-1 and the second camera 114-1 in this scheme differ in vertical height, that is, they do not lie on the same plane. This design enables the first camera 111-1 and the second camera 114-1 to be staggered, so as to possibly cover a wider scanning area to adapt to different use scenarios and needs.

[0058] As Figure 3As shown, in one specific embodiment, the first scanning assembly 111 includes a first camera 111-1 and a first light supplement lamp 111-2. The first camera 111-1 on the first scanning assembly 111 and the second light supplement lamp 114-2 on the second scanning assembly 114 are located on the same horizontal line, and the first light supplement lamp 111-2 on the first scanning assembly 111 and the second camera 114-1 on the second scanning assembly 114 are located on the same horizontal line. That is, the first camera 111-1 and the second camera 114-1 in the embodiment are not located on the same horizontal line, but there is a height difference in the vertical direction. Such staggered layout allows the two cameras to capture images at different heights, increasing the flexibility and coverage of the scan.

[0059] Those skilled in the art can understand that in the present scheme, the positions of the first camera 111-1 and the second camera 114-1 are not strictly limited, but a certain flexibility is provided. This means that according to the actual application scene and demand, the positions of the two cameras can be adjusted accordingly. As long as the first camera 111-1 and the second camera 114-1 are not arranged at the same horizontal height.

[0060] In addition, the connection angle between the mounting seat of the second scanning assembly 114 and the end face of the mounting end is not specifically limited, which provides flexibility for installation. For example, the mounting seat of the first scanning assembly 112 is vertically mounted on the end face, while the mounting seat of the second scanning assembly 114 is not vertically mounted, but can be obliquely mounted on the end face. This design allows the second scanning assembly 114 to have an angle difference with the first scanning assembly 112. Such an arrangement means that the first camera 111-1 and the second camera 114-1 are not only staggered, but also have different angles between them. Further increasing the differentiation of the scanning areas of the two cameras allows the handheld learning machine to cover a wider area.

[0061] In one specific embodiment, the horizontal distance between the center of the first scanning assembly and the center of the second scanning assembly is 9-35 mm.

[0062] Those skilled in the art can understand that the distance between the cameras has a direct impact on the scanning effect. If the distance between the two cameras is too close, it may cause the repeated scanning area to be too large, which not only reduces the scanning efficiency, but also may cause redundant data processing. Conversely, if the distance between the two cameras is too far, there may be a blank between their scanning areas, missing some important scanning content, affecting the integrity and accuracy of the scan.

[0063] Therefore, the distance between the centers of the first scanning assembly 111 and the second scanning assembly 114 is set to be in the range of 9mm-35mm in the present solution. Such design not only ensures that there is enough distance between the two cameras to avoid too large repeated scanning area, but also ensures that the distance between them is not too far, thereby avoiding the problem of missing scanning content.

[0064] It is worth noting that, Figure 1b - Figure 3 The figures are specifically used to show the layout of the first scanning assembly and the second scanning assembly on the end face of the handheld learning machine mounting end. The figures specifically depict the relative positions and mounting modes of the two scanning assemblies so as to better understand how they cooperate with the end face of the mounting end, and do not show other components on the handheld learning machine.

[0065] It can be understood by those skilled in the art that the type of the camera in the first scanning assembly and the second scanning assembly is not specifically limited in the present solution, which can be the fisheye camera mentioned in the above solution, or other types of cameras.

[0066] The handheld learning machine 100 provided by the present disclosure is provided with the first scanning assembly 111 and the second scanning assembly 114, and both are mounted on the obliquely arranged end face. Such double scanning assembly configuration not only can cover a larger text area, but also can reduce the number of user operations during scanning, thereby improving the overall use experience.

[0067] As Figure 1a shown, in some embodiments, the handheld learning machine provided by the present disclosure is further provided with a knob for adjusting the volume. Specifically, the knob 105 is arranged on the front side wall 101, and the knob 105 is in communication connection with the control board. In use, the user holds the handheld learning machine 100 to perform scanning operation, and the thumb is in abutment with the front side wall 101. When it is necessary to adjust the volume, the thumb is directly positioned to the position where the knob 105 is located, and then the knob 105 is rotated to increase or decrease the volume, which is more convenient to operate.

[0068] In a specific embodiment, a potentiometer is arranged inside the knob 105, and the potentiometer is connected to the control board through a wire. Specifically, a through hole is arranged on the bottom wall or the peripheral wall of the groove for the wire to pass through, so that the wire passes through the through hole and is connected with the controller inside the body. In use, the potentiometer changes its resistance value by rotation, thereby generating a voltage signal corresponding to the volume. This signal needs to be transmitted to the control board, and the control board adjusts the output volume through the internal audio processing circuit according to the signal received from the potentiometer.

[0069] As can be appreciated by those skilled in the art, in other embodiments, instead of arranging the potentiometer on the knob, an infrared sensing device can be arranged on the handheld learning machine and in communication with the control board, the infrared sensing device being arranged towards the knob for detecting the rotation angle of the knob and transmitting the detected rotation angle to the control board. That is, the knob is in communication with the control board through the sensing device. Specifically, the sensing device can be arranged in the groove or on the front side wall or inside the body of the handheld learning machine as needed.

[0070] In some embodiments, in order to improve the operation experience of the user and ensure stability when adjusting the volume, an anti-slip texture is particularly arranged in the knob design of the handheld learning machine. The anti-slip texture can be arranged in the form as shown in FIG. 4, on the outer peripheral region of the knob, or at other positions on the upper surface of the knob. The specific form of the anti-slip texture can be arranged as needed. For example, the anti-slip texture can be a specific decoration protruding on the upper surface of the knob. Figure 1a

[0071] In a specific embodiment, the front side wall 101 of the handheld learning machine 100 provided in the present solution has a groove 104 extending towards the rear side wall 102, the groove 104 being sized and profiled to accommodate the knob 105. When installed, the knob 105 is placed in the groove 104, and then fasteners are sequentially passed through the central shaft of the knob 105 and the bottom wall of the groove 104 to fix the knob 105 in the groove 104. When in use, the knob 105 is rotated around the fasteners to adjust the volume.

[0072] In the present solution, the thickness of the knob 105 is greater than the depth of the groove 104, and when the knob 105 is fixed in the groove 104, the upper surface of the knob 105 is arranged protruding from the outer surface of the front side wall 101. It should be noted that the thickness direction of the knob 105 is the same as the thickness direction of the body, i.e., the extension direction of the front side wall 101 towards the rear side wall 102.

[0073] As can be appreciated by those skilled in the art, in other embodiments, the thickness of the knob 105 is less than or equal to the depth of the groove 104. That is, in other embodiments, when the knob 105 is fixed in the groove 104, the upper surface of the knob 105 is flush with or lower than the outer surface of the front side wall 101, which also falls within the protection scope of the present solution. In the present solution, the knob 105 is flush with or slightly lower than the outer surface of the front side wall 101, which design maintains the overall aesthetics of the device, without protruding parts, making the appearance of the device more neat and coordinated. In addition, such design also reduces the possibility of accidental touch leading to volume change, especially when the device is carried or stored, which can avoid the inconvenience caused by accidental touch.​

[0074] In addition, in the present solution, the width of the knob 105 is smaller than the width of the groove 104 to which it is adapted. Those skilled in the art can understand that if the width of the knob 105 is equal to the width of the groove 104, the knob will not be able to rotate smoothly in the groove 104, which will seriously affect the user's operation experience and may cause the knob to malfunction. Only when the width of the knob 105 is smaller than the width of the groove 104, the user's finger can easily exert a rotating force on the knob 105, thereby achieving the adjustment of the volume.

[0075] Those skilled in the art can also understand that in other embodiments, no groove 104 is provided on the front side wall 101, and the knob 105 is directly mounted on the outer surface of the front side wall 101, which can also achieve the solution of the present application.

[0076] In some embodiments, the body in the present solution is equipped with a pressure sensor in communication with the control panel, which mainly functions to receive the pressing signal of the knob 105. Specifically, the process of adjusting the volume includes the following two steps: rotating the knob 105 to adjust the volume: the user first increases or decreases the volume by rotating the knob 105 until the desired volume level is reached. Confirm the volume setting: after the volume is adjusted to the size preset by the user, the user needs to confirm this setting by sending a pressing signal to the pressure sensor. Once confirmed, the device will use the determined volume for subsequent voice playback. This design in the present solution allows the user to have a clear confirmation step when adjusting the volume, ensuring the accuracy and stability of the volume setting. Through the combined operation of rotating the knob 105 and pressing the confirmation, the user can more accurately control the volume, while avoiding accidentally changing the set volume during the adjustment process.

[0077] In a specific embodiment, the outer surface of the bottom wall of the groove 104 is in abutment with the knob 105, and the pressure sensor is fixed on the inner surface of the bottom wall of the groove 104. That is, the pressure sensor in the present solution does not directly contact the knob 105, but indirectly contacts the knob 105 through the bottom wall of the groove 104. When the user needs to confirm the volume, press the knob 105, the knob 105 will exert a force on the bottom wall of the groove 104, and the bottom wall will transmit the force to the pressure sensor. Since the knob 105 does not directly contact the pressure sensor, it is less likely that the user will accidentally trigger the pressure sensor when rotating the knob 105, thereby reducing the possibility of misoperation.

[0078] In a specific embodiment, in order to make the knob have an adjustment feel during rotation, a damping device can be provided in the groove. For example, the damping device can be a uniformly arranged protruding structure provided on the peripheral wall of the groove.

[0079] In one specific embodiment, to facilitate user adjustment of the volume, a specific location on the front side wall is set as a standard position, serving as a reference point for volume adjustment. At the same time, the knob is equipped with scale markings such as pointers or numbers, which clearly display the current volume size.

[0080] When using the handheld learning machine, the user can rotate the knob to align the scale markings on the knob with the standard position on the front side wall. This design makes the volume adjustment process intuitive and easy to operate, and the user only needs to align the desired volume scale marking with the standard position on the front side wall to achieve accurate volume adjustment. This design not only improves the user's operation convenience, but also makes the volume control more accurate and reliable.

[0081] In another specific embodiment, the volume adjustment mechanism of the handheld learning machine is further optimized by combining pressure sensors to achieve more accurate and convenient operation. Specifically, in addition to setting a standard position on the front side wall and providing scale markings on the knob to indicate the current volume size, this scheme also introduces pressure sensor technology.

[0082] When adjusting the volume, the user first rotates the knob to align the desired volume scale marking with the standard position on the front side wall. This step allows the user to visually see and select the desired volume level. Subsequently, the user applies pressure to the pressure sensor to issue a pressing signal, which confirms the user's selected volume setting.

[0083] With this combination of visual and tactile feedback, the user can more accurately adjust and confirm the desired volume. The introduction of pressure sensors not only improves the convenience of operation, but also reduces the possibility of misoperation, making the volume adjustment process more intuitive and reliable. This design fully considers the user's operation habits and experience, improving the practicality and user satisfaction of the handheld learning machine.

[0084] In some embodiments, the handheld learning machine 100 has a thumb positioning area 107 on the front side wall 101. Specifically, in the present scheme, the thickness of the knob 105 is greater than the depth of the groove 104, that is, the upper surface of the knob 105 is convexly arranged on the outer surface of the front side wall 101. In addition, the front side wall 101 also has a display window 106 convexly arranged on its outer surface, and the thumb positioning area 107 refers to the area between the lower end of the display window 106 and the upper end of the knob 105. The presence of the thumb positioning area 107 in the present scheme takes into account ergonomics, and such design allows the user to naturally place the thumb in the thumb positioning area 107 when using the handheld learning machine 100, facilitating single-handed operation and quickly finding the knob 105 through the thumb positioning area 107 for volume adjustment, thereby improving operational efficiency. In addition, when using the handheld learning machine 100 in a mobile or unstable environment, the thumb positioning area 107 can provide better grip and reduce the risk of the handheld learning machine 100 slipping.

[0085] In a specific embodiment, the thumb positioning area 107 is provided with a recessed structure designed to provide a comfortable placement position for the user's thumb. Such recessed design not only conforms to the principle of ergonomics, but also ensures that the user's thumb can be naturally placed in the recessed position when using the device, thereby quickly and accurately positioning the knob 105 for operation.

[0086] In some embodiments, the vertical distance between the lower end of the display window 106 and the upper end of the knob 105 is 10-20 mm. That is, the height of the thumb positioning area 107 in the present scheme ranges from 10 mm to 20 mm. The present scheme takes into account that different users have different habits of holding the pen, and therefore introduces an adjustable thumb positioning area 107 in the design of the handheld learning machine, which is designed to have a specific height range to meet the grip habits of different users. Such design allows users to choose to place their thumbs at different heights in the positioning area according to their comfort and preferences.

[0087] The handheld learning machine 100 of the present disclosure also includes a speaker. Specifically, the speaker is arranged on the rear side wall 102 for voice broadcast. Specifically, the speaker is arranged opposite the display window 106.

[0088] In a specific embodiment, the handheld learning machine 100 provided by the present disclosure not only has a knob 105 on the front side wall 101, but also has a volume button 108 on a right side wall 103-1 connected to the front side wall 101 and perpendicular to each other. The present scheme provides two different volume adjustment methods, the knob 105 and the button 108, to meet the usage habits and preferences of different users. Users can choose to use the knob 105 or the button 108 according to their holding methods, and either way can quickly adjust the volume, thereby improving the convenience of operation.

[0089] The knob 105 and the volume button 108 can work independently, that is, control different speakers respectively, and different speakers are used for different scenes, for example, one speaker is used for playing the recognized text during scanning, and the other speaker is used for playing the voice of other applications of the device, such as a smart assistant. The knob 105 and the volume button 108 can also work cooperatively. When the knob 105 and the volume button 108 work cooperatively, the user can select the most suitable operation mode according to his own preference and the current use scene. For example, the user can first use the knob 105 to make a rough adjustment to find the approximate volume range, and then use the volume button 108 to make a fine adjustment to achieve accurate volume control. Or, when the volume needs to be adjusted quickly, the user can directly use the volume button 108 to operate.

[0090] In a specific embodiment, the knob 105 is cylindrical. The cylindrical design conforms to the natural holding shape of the fingers, can provide better grip feeling and operation comfort, and reduce the user's fatigue during use.

[0091] In some embodiments, the vertical distance between the center of the knob and the end of the shell for abutting the object to be scanned is 20-40 mm. The height of the knob when the body is in the vertical state is described in this scheme. This height range makes the knob 105 neither too close to the lower end of the handheld learning machine 100, avoiding the need for the user's thumb to move a large amplitude or the protruding knob blocking the user's view when adjusting the volume, nor too close to the middle area of the handheld learning machine 100 so that the height of the thumb positioning area 107 is high. In turn, it provides better user experience.

[0092] The handheld learning machine provided by the present disclosure can more conveniently adjust the volume and improve the user's experience.

[0093] In some embodiments of the present disclosure, a microphone 115 protrudingly arranged on one end of the body opposite to the mounting end is in communication connection with the control panel.

[0094] The handheld learning machine 100 provided by the present disclosure, through the microphone 115 arranged on the end opposite to the scanning end, not only facilitates the user to align the mouth during voice interaction, but also ensures the clarity and accuracy of voice input.
