[0030] The specific implementation of the present disclosure is described in detail below with reference to the accompanying drawings.

[0031] The present disclosure provides a handheld learning machine, which can be a dictionary pen, a listening and speaking device, a repeater, a learning machine, etc., and is used to realize the basic functions of the dictionary pen, the listening and speaking device, the repeater, the learning machine, etc. The following example introduces the content of this solution in detail.

[0032] In some embodiments, the handheld learning machine includes a main body and a control panel fixedly installed in the main body, and the handheld learning machine also includes: a mounting end, which is arranged at one end of the length direction of the main body, and the mounting end has an inclined end face, and at least a first scanning component communicatively connected to the control panel is installed on the end face, wherein the first scanning component is provided with a mounting seat, and the mounting seat is vertically installed on the end face; a supporting part, one end of which is connected to the mounting end, and the other end is extended away from the mounting end along the length direction, and the other end is used to abut against the object to be scanned; the supporting part has a scanning window; and a speaker, which is arranged on the main body and communicatively connected to the control panel; the speaker is used to play scanning-related content.

[0033] like Figure 1a - Figure 1cAs shown, in a specific embodiment, the design of the handheld learning machine 100 includes a rectangular body, which contains a control panel responsible for handling the operation and function of the device. At one end of the length direction of the handheld learning machine 100 body, a mounting end 113 and a support portion 109 are specially designed, and these two components together constitute the scanning mechanism of the handheld learning machine 100.

[0034] Specifically, the mounting end 113 has an inclined end surface, on which at least the first scanning component 111 that is in communication with the control board is mounted. Connected to the mounting end 113 is a support portion 109, one end of which is connected to the mounting end 113, and the other end of which is extended away from the mounting end along the length direction and in contact with the object to be scanned, playing a role of stability and support. In addition, a scanning window is provided on the support portion 109, and when in use, the user aligns the scanning window with the text so that the first scanning component 111 can capture the text information and process it.

[0035] When the handheld learning machine 100 in this solution is in a vertical state, the end face at the mounting end is not horizontally arranged, but tilted, and a mounting seat is arranged on the first scanning component 111, and the mounting seat is vertically mounted on the tilted end face, so the first scanning component 111 is also tilted, and there is an angle between it and the horizontal plane. The purpose of this setting 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.

[0036] In a specific implementation, the body of the handheld learning machine 100 in this solution is also provided with a speaker 120, which is in communication with the control board inside the body. When in use, the information acquired by the first scanning component is sent to the control board, and the information is processed by the processing module on the control board and then sent to the speaker 120, and the speaker 120 plays the scanned content.

[0037] In a specific embodiment, the first scanning component 111 includes a first camera 111-1 and two first fill lights 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 perform further processing and recognition. The first fill lights 111-2 are used in conjunction with the first camera 111-1 to provide additional light during the scanning process to ensure that the camera can capture a clear and easy-to-recognize image.

[0038] In a specific embodiment, the angle between the extension of the inclined end surface to the horizontal direction and the horizontal plane is 0 degrees to 36 degrees. Such a design means that the angle between the first scanning component 111 arranged on the end surface and the horizontal plane is also 0 degrees to 36 degrees. Those skilled in the art can understand that the setting of such an inclined angle is to enable the user to more conveniently align the object to be scanned during scanning.

[0039] Compared with the traditional arrangement in which the end face of the mounting end 113 is parallel to the object to be scanned, the tilted end face of the present solution makes the first scanning component 111 more inclined to face the object to be scanned when in use. This design not only improves the user's comfort, but also achieves a larger scanning range because the scanning component can be more directly aligned with the text. Therefore, this tilted end face design not only improves the user experience, but also improves the scanning efficiency and range of the handheld learning machine.

[0040] In a specific implementation scheme, when the body of the handheld learning machine 100 is in a vertical state, the vertical distance between the center of the first scanning component 111 and the plane where the end of the support portion 109 away from the mounting end 113 is located is 15mm-35mm. In other words, the height range of the first scanning component 111 in this solution is 15mm-35mm. The height range provided by this solution helps to select a larger FOV (camera field of view), thereby expanding the scanning range. In addition, the height range in this solution can reduce the interference of the shadow of fingers or equipment on the scanning results and improve the accuracy of the scanning.

[0041] The above solution introduces the mounting end and the first scanning assembly 111 in detail, and the structure of the supporting portion 109 is introduced in detail next.

[0042] In a 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, and the shell includes a front side wall 101 and a rear side wall 102 that are arranged opposite to each other, and a left side wall 103 and a right side wall 103-1 that are respectively connected to the front side wall 101 and the rear side wall 102. The shell can be manufactured in an integrated molding manner, which directly forms a complete shell structure through a single material or mold, thereby ensuring the strength and integrity of the shell. On the other hand, the shell can also be spliced ​​by various side walls, and this modular design allows a more flexible manufacturing and assembly process. For example, the left side wall and the right side wall can be respectively arranged on the front side wall or the rear side wall, and the shell is surrounded by abutment. This design makes the connection of each side wall more flexible and convenient for assembly and maintenance. In addition, the front side wall and the rear side wall can be designed with extension sections at both ends in the width direction, and these extension sections can abut each other to form a left side wall and a right side wall. In other words, the division of each side wall in this scheme is defined for the formed body, rather than defined according to the manufacturing process.

[0043] 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 first extends away from the mounting end 113 along the length direction, and then extends to the extension surface of the rear side wall 102 of the body. One end of a second support portion 1092 is connected to the left side wall 103 of the body at the mounting end 113, and the other end first extends away from the mounting end 113 along the length direction, and then extends perpendicularly to the extension surface of the right side wall 103-1. One end of another 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 first extends away from the mounting end 113 along the length direction, and then extends perpendicularly to the extension surface of the left side wall 103.

[0044] 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 form a scanning window. The handheld learning machine 100 provided in this solution is also provided with a pressure sensing component that is connected to the control board for communication. The pressure sensing component can be provided only on the first support portion 1091, or can be provided on both the first support portion 1091 and the second support portion 1092. Of course, those skilled in the art can understand that the setting position of the pressure sensing component can also be set at other positions according to actual conditions.

[0045] It is worth noting that the first support portion 1091 in this solution has two extension sections, one of which extends along the length direction of the body, and the other 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, the first extension section extends along the length direction of the body, and the other extension section extends along the width direction of the body, and the connection between the two extension sections is also a smooth arc.

[0046] In another specific embodiment, the scanning window of the handheld learning machine 100 is surrounded by several specific components, including the extended end of the first support portion 1091, the extended ends of the two second support portions 1092, and the end of the extended section of the rear side wall 102 of the body at the mounting end 113. One end of the extended section on the body is connected to the rear side wall 102, and the other end is extended away from the mounting end 113 along the length direction.

[0047] Specifically, an extension section is provided on the rear side wall 102 of the body at the mounting end 113, and the end of the extension section, together with the end of the first support portion 1091 and the ends of the two second support portions 1092, constitute the boundary of the scanning window. This 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.

[0048] It is worth noting that in the present solution, the scanning window is designed to have a preset width, specifically ranging from 28 mm to 43 mm. This width refers to the extension direction from the left side wall 103 of the body to the right side wall 103-1, that is, the scanning window is extended along the width direction of the handheld learning machine 100. In addition, the scanning window is designed to be arc-shaped at both ends in the width direction. That is, the ends of the two second support portions 1092 are arranged to be bracket-shaped structures. This design not only provides a clear scanning area, but the arc-shaped end design helps to reduce the discomfort that the edge of the scanning window may cause to the user, while also increasing the aesthetics.

[0049] In a specific embodiment, in order to prevent the end of the first support portion 1091 from blocking the first scanning component 111, the position and shape of the first support portion 1091 are specially designed in this solution. Specifically, when the body of the handheld learning machine 100 is in a vertical state, the extended end of the first support portion 1091 is designed not to exceed the projection of the first scanning component 111 on the horizontal plane. Such design logic ensures that the first scanning component 111 will not be interfered by the end of the first support portion 1091 during the scanning operation, thereby ensuring the smoothness of the scanning process and the accuracy of the scanning results.

[0050] It can be understood by those skilled in the art that the extension length of the first support portion 1091 is designed to be greater than the extension length of the extension section of the rear side wall 102. When the body of the handheld learning machine 100 is in a vertical state, the end of the end face that is close to the object to be scanned is connected to the front side wall 101, and the end of the end face that is far from the object to be scanned is connected to the rear side wall 102. That is to say, in this solution, the length of the front side wall 101 is greater than the length of the rear side wall 102, and one end of the end face of the mounting end 113 is connected to the rear side wall 102, and the other end is connected to the front side wall 101. This solution enables the first scanning component 111 to perform the scanning operation better by limiting the inclination direction of the end face.

[0051] In some specific embodiments, those skilled in the art will appreciate that the support portion may be formed integrally with the housing, or may be formed by splicing independent components. When the support portion is formed integrally with the housing, the first support portion is formed by the end of the front side wall extending downward, and the two second support portions are formed by the ends of the left side wall and the right side wall extending downward.

[0052] When the support portion and the housing are not integrally formed, the support portion and the housing are several independently arranged parts, and then fixed together by gluing or other methods. At this time, in order to prevent the support portion 109 and the extension section of the rear side wall 102 from blocking the content to be scanned, the present solution uses a transparent material to make the support portion 109 and the extension section of the rear side wall 102. For example, the transparent material can be glass, plastic, etc.

[0053] In some embodiments, the handheld learning machine 100 in this solution has a larger scanning range due to the design of the end face and the setting position and height of the first scanning component 111. Specifically, when the body of the handheld learning machine 100 is in a vertical state, since the first scanning component 111 is set on the inclined end face, the first scanning component 111 has a preset range of scanning intervals in the direction toward the rear side wall 102. Specifically, the scanning length range of the scanning interval is set between 25mm and 80mm, and the scanning width range of the scanning interval is between 35mm and 80mm. This design allows the handheld learning machine 100 to cover a wide range of text areas in different directions. In this solution, the direction of the scanning length is along the extension direction from the front side wall 101 to the rear side wall 102 of the handheld learning machine 100 body, which means that the user can scan a longer text line along this direction. The extension direction of the scanning width is from the left side wall 103 of the body to the right side wall 103-1, 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.

[0054] Of course, those skilled in the art can understand that the scanning range of the first scanning component 111 in the handheld learning machine is determined by two key factors: one is the tilt angle range of the first scanning component 111, and the other is the distance range between the first scanning component 111 and the end of the first support portion 1091. This design takes into account the tilt setting of the scanning component on the end face, as well as its relative position to the support structure, thereby ensuring the flexibility and adaptability of the scanning range. By carefully designing the distance between the first scanning component 111 and the support portion 109, as well as the tilt angle of the first scanning component 111, the handheld learning machine 100 can achieve a wide and flexible scanning range. This not only improves the accuracy and efficiency of the scan, but also enables the handheld learning machine 100 to meet a variety of scanning needs, thereby enhancing its competitiveness in the market.

[0055] It is worth noting that the structure of the support portion is not limited to the shape described in this solution, and it can have many different design forms. For example, the support portion can be as follows Figure 4 and Figure 5 The structure shown specifically includes four peripheral walls, and the extension length of the front peripheral wall is greater than the extension length of the rear peripheral wall. That is to say, in other schemes, the support part can adopt other shapes and structures according to specific application needs and design requirements to adapt to different usage scenarios and functional requirements. Although these different structural designs are different from the support part described in this scheme in appearance and structure, their core purpose is still to cooperate with the end face of the mounting end and the first scanning component to achieve the effect of increasing the scanning range.

[0056] like Figure 2a - Figure 2c As shown, in a specific embodiment, the first scanning component is a fisheye camera. It will be appreciated by those skilled in the art that, since the fisheye camera has a unique profile, the mounting base of the fisheye camera is a shell 119 that is covered on its periphery, and the shell 119 is inserted into a mounting groove provided on the mounting end for fixation. Since the end face of the mounting end in this solution is tilted, the fixed end of the shell is fixed perpendicular to the tilted end face. When the handheld learning machine is in a vertical state, an angle is formed between the fisheye camera and the horizontal line, and the angle is 0 to 15 degrees. That is to say, in this embodiment, the angle between the extended surface of the end face of the mounting end and the horizontal plane is also 0 to 15 degrees.

[0057] The fisheye camera provided by this solution can capture more text or images at one time, significantly expanding the range of a single scan, so when performing scanning tasks, users can reduce the number of scans required. This solution not only saves time, but also reduces the labor intensity of users during the scanning process.

[0058] In a specific implementation scheme, in order to further improve the scanning range of the handheld learning machine 100, a second scanning component 114 is also provided on the end face of the mounting end 113 of the handheld learning machine 100, and the second scanning component 114 is arranged at an interval from the first scanning component 111. In other words, the handheld learning machine 100 provided in this scheme is provided with two scanning components, so that more content can be scanned. In order to adapt to the two scanning components, a processing module is also provided on the control board in this scheme, and the function of the processing module is to sort out the content scanned by the first scanning component 111 and the second scanning component 114, for example, after deleting the duplicate content, the remaining content is integrated.

[0059] In a specific embodiment, the second scanning assembly 114 is also mounted on an inclined end surface at one end of the body in the length direction, and a mounting seat is provided thereon, and the mounting seat is vertically fixed on the end surface, so that the second scanning assembly 114 is also arranged obliquely. Specifically, the second scanning assembly 114 includes two parts, namely, a second camera 114-1 and a second fill light 114-2. Such a design enables the second scanning assembly 114 to work in coordination with the first scanning assembly 111, thereby improving scanning efficiency and accuracy.

[0060] It is worth noting that the first camera 111-1 and the second camera 114-1 in this solution have a difference in vertical height, that is, they are not located on the same plane. This design allows the first camera 111-1 and the second camera 114-1 to be staggered, thereby covering a wider scanning area to adapt to different usage scenarios and needs.

[0061] like Figure 3 As shown, in a specific embodiment, the first scanning component 111 includes a first camera 111-1 and a first fill light 111-2. The first camera 111-1 on the first scanning component 111 and the second fill light 114-2 on the second scanning component 114 are located on the same horizontal line, and the first fill light 111-2 on the first scanning component 111 and the second camera 114-1 on the second scanning component 114 are located on the same horizontal line. In other words, the first camera 111-1 and the second camera 114-1 in this embodiment are not located on the same horizontal line, but there is a height difference in the vertical direction. This staggered layout allows the two cameras to capture images at different heights, increasing the flexibility and coverage of scanning.

[0062] Those skilled in the art can understand that, in this solution, there is no strict restriction on the location of the first camera 111-1 and the second camera 114-1, but a certain flexibility is provided. This means that the locations of the two cameras can be adjusted accordingly according to actual application scenarios and requirements. It is sufficient as long as the first camera 111-1 and the second camera 114-1 are not arranged at the same horizontal height.

[0063] In addition, there is no specific limitation on the connection angle between the mounting base of the second scanning component 114 and the end face of the mounting end, which provides flexibility for installation. For example, the mounting base of the first scanning component 112 is vertically mounted on the end face, while the mounting base of the second scanning component 114 is not vertically mounted, but can be tilted on the end face. This design allows an angle difference between the second scanning component 114 and the first scanning component 112. This 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. This further increases the differentiation of the scanning areas of the two cameras, allowing the handheld learning machine to cover a wider area.

[0064] In a specific embodiment, the horizontal distance between the center of the first scanning assembly and the center of the second scanning assembly is 9 mm-35 mm.

[0065] It is understood by those skilled in the art that the distance between the cameras has a direct impact on the scanning effect. If the distance between the two cameras is too close, the area to be repeatedly scanned may be too large, which not only reduces the scanning efficiency, but also may cause data processing redundancy. On the contrary, if the distance between the two cameras is too far, the scanning area between them may be blank, thereby missing some important scanning content, affecting the integrity and accuracy of the scan.

[0066] Therefore, in this solution, the distance between the centers of the first scanning component 111 and the second scanning component 114 is set within the range of 9mm-35mm. Such a design ensures that there is enough distance between the two cameras to avoid excessive repeated scanning areas, and ensures that the distance between them is not too far, thereby avoiding the problem of missing scanned content.

[0067] It is worth mentioning that Figure 1c - Figure 3 Specially used to show the layout structure of the first scanning component and the second scanning component on the end surface of the mounting end of the handheld learning machine. These illustrations depict the relative positions and mounting methods of the two scanning components in detail to better understand how they cooperate with the end surface of the mounting end, and do not show other components on the handheld learning machine.

[0068] Those skilled in the art will appreciate that the present solution does not specifically limit the types of cameras in the first scanning component and the second scanning component, and they may be the fisheye cameras mentioned in the above solution, or other types of cameras.

[0069] The handheld learning machine 100 provided in the present disclosure has a first scanning component 111 and a second scanning component 114, and both are installed on an inclined end surface. This dual scanning component configuration can not only cover a larger text area, but also reduce the number of user operations during the scanning process, thereby improving the overall user experience.

[0070] like Figure 1a As shown, in some embodiments, the handheld learning machine provided by the present disclosure is also provided with a knob for adjusting the volume. Specifically, the knob 105 is provided on the front side wall 101, and the knob 105 is communicatively connected with the control panel. When in use, the user holds the handheld learning machine 100, performs a scanning operation, and the thumb abuts against the front side wall 101. When the volume needs to be adjusted, the thumb is directly positioned at the position where the knob 105 is located and then rotated to increase or decrease the volume, which is more convenient to operate.

[0071] In a specific embodiment, a potentiometer is provided inside the knob 105, and the potentiometer is connected to the control board via a wire. Specifically, a through hole for the wire to pass through is provided on the bottom wall or the peripheral wall of the groove, and the wire is connected to the controller inside the body through the through hole. When in use, the potentiometer changes its resistance value by rotating, 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.

[0072] It can be understood by those skilled in the art that, in other solutions, the potentiometer may not be provided on the knob, but an infrared sensing device that is communicatively connected to the control board may be provided on the handheld learning machine, and the infrared sensing device is arranged toward the knob to detect the rotation angle of the knob and transmit the detected rotation angle to the control board. In other words, the knob is communicatively connected to the control board via the sensing device. Specifically, the sensing device may be provided in the groove, and may also be provided on the front side wall of the handheld learning machine or inside the body as required.

[0073] In some implementations, in order to improve the user's operating experience and ensure stability when adjusting the volume, an anti-slip texture is specially added to the knob design of the handheld learning machine. The anti-slip texture can be set in the following manner: Figure 1a The form shown in the figure is arranged in the peripheral area of ​​the knob, and can also be arranged at other positions on the upper surface of the knob. As for the specific form of the anti-slip texture, it can be arranged as needed. For example, the anti-slip texture can be a specific decoration protruding and arranged on the upper surface of the knob.

[0074] In a specific embodiment, the front side wall 101 of the handheld learning machine 100 provided by the present solution has a groove 104 extending in the direction of the rear side wall 102, the size and contour of which are adapted to the knob 105, and the knob 105 is fixedly installed in the groove 104. During installation, after the knob 105 is placed in the groove 104, a fastener is then passed through the central axis of the knob 105 and the bottom wall of the groove 104 in sequence, thereby fixing the knob 105 in the groove 104. During use, the knob 105 is rotated around the fastener to adjust the volume.

[0075] In this solution, the thickness of the knob 105 is greater than the depth of the groove 104. When the knob 105 is fixed in the groove 104, the upper surface of the knob 105 is protruding from the outer surface of the front side wall 101. It is worth noting that the thickness direction of the knob 105 is the same as the thickness direction of the body, that is, the extension direction of the front side wall 101 to the rear side wall 102.

[0076] Those skilled in the art may also understand that, in other embodiments, the thickness of the knob 105 is less than or equal to the depth of the groove 104. That is to say, in other embodiments, when the knob 105 is fixed in the groove 104, the upper surface of the knob 105 is flush with the outer surface of the front side wall 101, or is lower than the outer surface of the front side wall 101, which also falls within the protection scope of this embodiment. In this embodiment, the knob 105 is flush with or slightly lower than the outer surface of the front side wall 101. This design maintains the overall beauty of the device, without protruding parts, making the appearance of the device more neat and coordinated. In addition, this design also reduces the possibility of accidental touch causing volume changes, especially when the device is carried or stored, it can avoid the inconvenience caused by accidental touch.

[0077] In addition, in this solution, the width of the knob 105 is smaller than the width of the groove 104 adapted thereto. It can be understood by those skilled in the art 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 operating experience and may cause the knob to not work properly. Only when the width of the knob 105 is smaller than the width of the groove 104, the user's finger can easily apply a rotational force on the knob 105 to adjust the volume.

[0078] Those skilled in the art may also understand that, in other embodiments, the groove 104 is not 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 implement the solution of the present application.

[0079] In some embodiments, the body in this solution is equipped with a pressure sensor that is communicatively connected to the control panel, and its main function is to receive a pressing signal from the knob 105. Specifically, the process of adjusting the volume includes the following two steps: Rotate 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: When the volume is adjusted to the user's preset level, 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 to confirm, the user can control the volume more accurately while avoiding accidentally changing the set volume during the adjustment process.

[0080] In a specific embodiment, the outer surface of the bottom wall of the groove 104 abuts against the knob 105, and the pressure sensor is fixed on the inner surface of the bottom wall of the groove 104. That is to say, the pressure sensor in this 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, the knob 105 is pressed, and the knob 105 applies a force to the bottom wall of the groove 104, and the bottom wall transmits the force to the pressure sensor. Since the knob 105 is not in direct contact with 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.

[0081] In a specific embodiment, in order to make the knob have an adjustable feel during rotation, a damping device may be provided in the groove. For example, the damping device may be a uniformly arranged convex structure provided on the peripheral wall of the groove.

[0082] In a specific embodiment, in order to facilitate the user to adjust the volume, a specific position of the front side wall is set as a standard position to indicate the reference point of the volume adjustment. At the same time, the knob is equipped with scale marks such as pointers or numbers, which are used to clearly display the current volume.

[0083] When using the handheld learning machine, the user can align the scale mark on the knob with the standard position on the front side wall by rotating the knob. This design makes the volume adjustment process intuitive and easy to operate. The user only needs to align the required volume scale mark with the standard position on the front side wall to achieve accurate volume adjustment. This design not only improves the user's operating convenience, but also makes the volume control more accurate and reliable.

[0084] In another specific implementation, the volume adjustment mechanism of the handheld learning machine is further optimized, and a more precise and convenient operation is achieved by combining a pressure sensor. Specifically, in addition to setting a standard position on the front side wall and setting a scale mark indicating the current volume on the knob, the solution also introduces pressure sensor technology.

[0085] When adjusting the volume, the user first rotates the knob to align the desired volume scale mark with the standard position on the front side wall. This step allows the user to intuitively see and select the desired volume level. The user then applies pressure to send a press signal to the pressure sensor, which confirms the volume setting selected by the user.

[0086] Through this design that combines visual and tactile feedback, users can adjust and confirm the required volume more accurately. The introduction of the pressure sensor 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 operating habits and experience, and improves the practicality and user satisfaction of the handheld learning machine.

[0087] In some embodiments, the front side wall 101 of the handheld learning machine 100 has a thumb positioning area 107. Specifically, in this solution, 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 set to protrude from the outer surface of the front side wall 101. In addition, the front side wall 101 also has a display window 106 protruding from 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 existence of the thumb positioning area 107 in this solution takes ergonomics into consideration. Such a design allows the user to naturally place the thumb in the thumb positioning area 107 when using the handheld learning machine 100, which is convenient for the user to operate with one hand, quickly find the knob 105 through the thumb positioning area 107, and adjust the volume, thereby improving the efficiency of the operation. In addition, when the handheld learning machine 100 is used in a mobile or unstable environment, the thumb positioning area 107 can provide a better grip and reduce the risk of the handheld learning machine 100 slipping.

[0088] In a specific embodiment, the thumb positioning area 107 is provided with a recessed structure, which is intended to provide a comfortable placement for the user's thumb. This 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 area when using the device, so as to quickly and accurately locate the knob 105 for operation.

[0089] In a specific embodiment, the speaker 120 is disposed on the rear side wall of the handheld learning machine 100, and the speaker 120 is disposed opposite to the display window 106. That is, the speaker 120 in this solution is also disposed in an area of ​​the body away from the scanning window, thereby preventing the user's hand from blocking the speaker 120 and ensuring clear transmission of sound.

[0090] like Figure 1b As shown, in a specific embodiment, the speaker 120 is arranged to protrude from the outer surface of the rear side wall. Specifically, the speaker 120 includes a first protrusion 1201 and a first protrusion 1202, wherein the first protrusion 1202 surrounds the outer periphery of the first protrusion 1201, and there is a gap between the two; a plurality of support members are arranged on the inner surface of the first protrusion 1201, and the support members are connected to the sound module, so that there is a hollow portion between the sound module and the first protrusion 1201.

[0091] In this solution, the speaker 120 is arranged to protrude from the outer surface of the rear side wall. Specifically, the speaker 120 includes a first protrusion 1201 and a first protrusion 1202, wherein the first protrusion 1202 surrounds the outer periphery of the first protrusion 1201, and there is a gap between the two. Such a structural design not only increases the stereoscopic sense of the speaker 120, but also provides a smoother channel for the propagation of sound, reducing the reflection and interference of the sound during the propagation process.

[0092] A plurality of support members are provided on the inner surface of the first protrusion 1201, and one end of the support member is connected to the sound module. These support members provide a hollow portion between the sound module and the first protrusion 1201. The hollow portion not only provides additional space for the propagation of sound, so that the sound can be fully diffused and mixed inside the speaker 120, thereby producing a richer and fuller sound effect. It also helps to improve the heat dissipation performance of the speaker 120 and extend its service life.

[0093] It is worth noting that the present solution does not limit the specific shapes of the first protrusion 1201 and the first protrusion 1202. That is, the first protrusion 1201 can be as shown in the attached figure. Figure 1b The square structure shown in the figure may also be other shapes, such as a circle. The shape of the first protrusion 1202 is adaptively adjusted according to the shape of the first protrusion 1201. For example, when the first protrusion 1201 is a square, the first protrusion 1202 may be designed to be a matching square surrounding structure to maintain overall consistency; if the first protrusion 1201 is a circle, the first protrusion 1202 is adjusted to a circular surrounding structure accordingly to achieve a coordinated and unified appearance.

[0094] Those skilled in the art can understand that the sound module in this solution is connected to the control board for communication, and its core function is to achieve sound generation. Specifically, the sound module at least includes a magnetic circuit system composed of a magnet and a magnetic plate, and a vibration system composed of a voice coil and a diaphragm.

[0095] like Figure 1b As shown, in a specific embodiment, the protrusion height of the first protrusion 1201 is lower than the protrusion height of the first protrusion 1202, and the outer surface of the first protrusion 1202 is an inclined surface arranged obliquely. In other words, the first protrusion 1202 has an outer contour and an inner contour, and the height of the inner contour is lower than the height of the outer contour.

[0096] Those skilled in the art will appreciate that, in order to better diffuse the sound, in other embodiments, the protruding height of the first protrusion 1201 is set to be greater than the protruding height of the first protrusion 1202. Such a structural design enables the sound to pass through the gap between the first protrusion 1201 and the first protrusion 1202 during the propagation process, thereby being diffused more smoothly to the surroundings.

[0097] Specifically, the higher protrusion height of the first protrusion 1201 provides a wider space for the propagation of sound, reducing the obstruction of sound during the propagation process. The first protrusion 1202 surrounds the outer periphery of the first protrusion 1201, and the gap between the two forms a channel for sound diffusion. When the sound is emitted from the sound module, it first propagates inside the first protrusion 1201, and then diffuses outward through the gap between the first protrusion 1201 and the first protrusion 1202, so that the sound can be evenly propagated in all directions, improving the sound propagation efficiency and coverage. This design not only optimizes the acoustic performance of the speaker 120, but also enhances the user's listening experience at different positions.

[0098] 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 mm to 20 mm. That is, the height range of the thumb positioning area 107 in this solution is 10 mm to 20 mm. This solution takes into account the different pen-holding habits of different users. An adjustable thumb positioning area 107 is specially introduced in the design of this handheld learning machine. The area is designed to be a specific height range to meet the gripping habits of different users. This design allows users to choose to place their thumbs at different heights in the positioning area according to their comfort and preferences.

[0099] In a specific embodiment, the handheld learning machine 100 provided by the present disclosure is not only provided with a knob 105 on the front side wall 101, but also provided with a volume button 108 on a right side wall 103-1 connected to the front side wall 101 and perpendicular to each other. In this solution, two different volume adjustment methods, the knob 105 and the button 108, are provided to meet the usage habits and preferences of different users. The user can choose to use the knob 105 or the button 108 according to his or her own holding method, and either method can quickly adjust the volume, which improves the convenience of operation.

[0100] The knob 105 and the volume button 108 can work independently, that is, they control different speakers respectively, and different speakers are used in different scenarios. For example, one speaker is used to play the text recognized during scanning, and the other speaker is used for other applications of the device, such as the sound of the smart assistant. The knob 105 and the volume button 108 can also work together. When the knob 105 and the volume button 108 work together, the user can choose the most appropriate operation mode according to his or her preferences and the current usage scenario. For example, the user can first use the knob 105 for coarse adjustment to find the approximate volume range, and then use the volume button 108 for fine adjustment to achieve precise volume control. Alternatively, when the volume needs to be adjusted quickly, the user can directly use the volume button 108 to operate.

[0101] In a specific embodiment, the knob 105 is cylindrical. The cylindrical design conforms to the natural gripping shape of fingers, can provide a better grip and operating comfort, and reduce the user's fatigue during use.

[0102] In some embodiments, the vertical distance between the center of the knob and the end of the housing for contacting the object to be scanned is 20mm-40mm. This solution describes the height of the knob when the body is in a vertical state. This height range prevents the knob 105 from being too close to the lower end of the handheld learning machine 100, which prevents the user's thumb from moving a large range when adjusting the volume or the protruding knob from blocking the user's line of sight, and it also prevents the knob from being too close to the middle area of ​​the handheld learning machine 100, which causes the thumb positioning area 107 to be at a higher height. This provides a better user experience for the user.

[0103] The handheld learning machine provided by the present disclosure can adjust the volume more conveniently and improve the user experience.

[0104] In some embodiments of the present disclosure, a microphone 115 is protruded from one end of the body opposite to the mounting end, and the microphone 115 is communicatively connected with the control board.

[0105] The handheld learning machine 100 provided by the present disclosure, through the microphone 115 set at 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. The user does not need to frequently adjust the direction of the device during use, but simply moves the device to the mouth to perform smooth voice input, whether it is to query word pronunciation, language learning or dialogue with the device, it can be easily completed. This integrated design not only optimizes the user's operating process, but also enhances the functionality of the device and improves the user's experience.

[0106] In a specific implementation, the microphone 115 is a directional microphone 115 .

[0107] The microphone 115 in this solution is a directional microphone 115, which can not only more effectively capture sounds from a specific direction, reduce background noise and sound interference from the side or back, thereby improving the clarity of speech, but also can reduce the inadvertent capture of conversations with other people by only capturing sounds from a specific direction, thereby improving privacy protection.

[0108] In a specific embodiment, the microphone 115 includes a cylindrical shell, one end of which is connected to the body, and the other end of which is extended away from the body along the length direction; the other end has an end surface, and a microphone hole is opened on the end surface.

[0109] The microphone 115 in this embodiment has a cylindrical shell, which has two ends in the length direction, one end is connected to the body, and the other end is extended away from the body along the length direction. In addition, the other end of the shell has an end surface, and the end surface has a plurality of microphone holes evenly arranged.

[0110] The microphone 115 provided in this solution can ensure that sound enters the microphone 115 evenly from multiple angles due to the microphone holes evenly distributed on the end surface, which helps to improve the efficiency and uniformity of sound capture, especially in scenarios where stereo or surround sound needs to be captured.

[0111] Those skilled in the art will appreciate that, in other embodiments, microphone holes may be provided not only on the end surface but also on the peripheral wall of the shell.

[0112] It can also be understood by those skilled in the art that the housing of the microphone 115 may not be a regular cylindrical shape. The specific shape can be set according to different requirements. For example, the housing of the microphone 115 can be designed to be composed of four peripheral walls connected to each other, and this design provides more flexibility and stability in structure. In order to enhance the aesthetics and reduce stress concentration during the production process, these peripheral walls are chamfered at the connection to make the curved surface of the connection smoother.

[0113] In a specific embodiment, the body includes an upper end wall 110 having a preset length and a preset width, and the microphone 115 is disposed at a central position of the upper end wall 110 .

[0114] In this solution, the body has an upper end wall 110 at one end away from the mounting end in the length direction. The upper end wall 110 has a preset length and a preset width. The microphone 115 is arranged at the center of the upper end wall 110 .

[0115] In a specific embodiment, the body includes an upper end wall 110 having a preset length and a preset width, and the microphone 115 is disposed in a region between the center of the upper end wall 110 and any edge in the length direction of the upper end wall 110. It is worth noting that the length direction of the upper end wall in this embodiment refers to the width direction of the body, and the width direction of the upper end wall refers to the thickness direction of the body.

[0116] In this solution, the body includes an upper end wall 110 having a preset length and a preset width, and the upper end wall 110 has a first edge and a second edge at both ends in the length direction. The microphone 115 can be arranged between the center of the upper end wall 110 and the first edge in the length direction of the upper end wall 110, or between the center of the upper end wall 110 and the second edge in the length direction of the upper end wall 110. When the body is in a vertical state, there is a center line passing through the center of the upper end wall 110, and the microphone 115 in this solution is not arranged along this center line, but is arranged offset from the center line.

[0117] In a specific embodiment, the upper end wall 110 further has a protruding connecting member 116 , and the connecting member 116 is further provided with a through hole, wherein the extending direction of the through hole is perpendicular to the protruding direction of the connecting member 116 .

[0118] The microphone 115 is disposed in a region between the center of the upper end wall 110 and one edge of the upper end wall 110 in the length direction, and the connector 116 is disposed in a region between the center of the upper end wall 110 and another edge of the upper end wall 110 in the length direction.

[0119] In this solution, the upper end wall 110 of the body has not only a protruding microphone 115, but also a protruding connector 116. The microphone 115 is arranged in the area between the center of the upper end wall 110 and one edge of the upper end wall 110 in the length direction, while the connector 116 is arranged in the area between the center of the upper end wall 110 and another edge of the upper end wall 110 in the length direction. This layout means that when the body is in a vertical state, the microphone 115 and the connector 116 are respectively located on both sides of the center line of the body and are symmetrically distributed at both ends in the length direction.

[0120] In addition, the connecting member 116 is also provided with a through hole, the extension direction of which is perpendicular to the protruding direction of the connecting member 116, that is, when the body is placed vertically, the protruding direction of the connecting member 116 is consistent with the body, in a vertical direction, while the through hole extends horizontally. This design allows the lanyard to pass through the through hole and fix it to the handheld learning machine 100, and then the lanyard can be conveniently hung around the user's neck.

[0121] This solution increases the portability and practicality of the device by providing a through hole on the connecting member 116. When the user needs to carry the device, he can directly put the lanyard around his neck, thereby freeing his hands and improving the convenience of use. In addition, this design also helps prevent the device from accidentally falling or being lost during carrying, thereby enhancing the safety of the device.

[0122] In a specific embodiment, the connector 116 and the microphone 115 are symmetrically arranged along the center of the upper end wall 110. Specifically, the connector 116 and the microphone 115 are symmetrically arranged along the center line of the upper end wall 110, that is, the two structures are not only located on both sides of the center of the upper end wall 110, but also are mirror-symmetrical relative to the center line of the body. This symmetrical layout not only provides a balanced and harmonious aesthetic visually, but also functionally helps to disperse the weight of the device, making it more stable and comfortable when in use.

[0123] In a specific embodiment, the size and shape of the connector 116 are the same as those of the microphone 115. That is, the microphone 115 and the connector 116 are not only symmetrically arranged in position, but also consistent in shape and size. This design means that the microphone 115 and the connector 116 have a mirror-symmetrical layout in appearance, and they are evenly distributed along the center line of the upper end wall 110, and are completely the same in size and shape. Such a consistent design provides a unified and coordinated visual perception, enhancing the overall aesthetics of the device.

[0124] The handheld learning machine 100 provided in the present disclosure, through the microphone 115 arranged at the end opposite to the scanning end, not only facilitates the user to aim at the mouth during voice interaction, but also ensures the clarity and accuracy of voice input, thereby improving the user experience.
