[0032] The specific embodiments of the present disclosure will be described in detail below with reference to the drawings.
[0033] The present disclosure provides a handheld learning machine, which can be a dictionary pen, a listening and speaking treasure, a tape recorder, a learning machine, etc., which is used to realize the basic functions of the dictionary pen, the listening and speaking treasure, the tape recorder, the learning machine, etc. Next, the content of the present solution will be introduced in detail.
[0034] As shown in Figure 1a The handheld learning machine 100 provided by the present solution includes a device body in the shape of a rectangular parallelepiped, and a control panel arranged inside the device body. One end of the device body in the length direction is provided with a scanning window and a scanning assembly in communication connection with the control panel. In use, the scanning window is in abutment with a book to be identified, and the scanning assembly scans a word or a phrase and transmits it to the control panel, and then performs a translation operation and outputs.
[0035] More specifically, the device body includes a front side wall 101 and a rear side wall 102 arranged opposite to each other, and a left side wall 103 connected to the front side wall 101 and the rear side wall 102 respectively, a knob 105 for adjusting the volume is arranged on the front side wall 101, and the knob 105 is in communication connection with the control panel, wherein the lengths of all the shells are the same, and the width of the front side wall 101 is greater than the width of the left side wall 103. In use, the user holds the handheld learning machine 100, performs a 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.
[0036] It is worth mentioning that the description in the present solution focuses on the individual housings of the molding device body, and does not involve the manufacturing process of the device body. Specifically, the housings of the device body can have various different manufacturing methods, for example, the individual housings are independently arranged, and then they are connected, for example, the upper rear side wall and the left side wall are integrally formed.
[0037] In a specific embodiment, the knob 105 is internally provided with a potentiometer connected to the control panel through a wire. Specifically, a through hole is provided on the bottom wall or the peripheral wall of the recess for the wire to pass through, and then the wire passes through the through hole and is connected to the controller inside the body. In use, the potentiometer changes its resistance value by rotating, thereby generating a voltage signal corresponding to the volume size. This signal needs to be transmitted to the control panel, and the control panel adjusts the output volume through the internal audio processing circuit according to the signal received from the potentiometer.
[0038] As understood by those skilled in the art, in other solutions, the potentiometer can not be provided on the knob, but an infrared sensing device is provided on the handheld learning machine and is in communication connection with the control panel. The infrared sensing device is arranged towards the knob for detecting the rotation angle of the knob and transmitting the detected rotation angle to the control panel. That is, the knob is in communication connection with the control panel through the sensing device. Specifically, the sensing device can be arranged in the recess, and can also be arranged on the front side wall of the handheld learning machine or inside the device body as needed.
[0039] In some embodiments, in order to improve the operation experience of the user and ensure the stability during the adjustment of the volume, anti-slip textures are specially added in the design of the knob of the handheld learning machine. The anti-slip textures can be arranged in the form as shown in Figure 1a , that is, arranged on the outer peripheral area of the knob, or can also be arranged at other positions on the upper surface of the knob. The specific form of the anti-slip textures can be arranged as needed. For example, the anti-slip textures can be protruding decorations arranged on the upper surface of the knob.
[0040] In a specific embodiment, the front side wall 101 of the handheld learning machine 100 provided in the present solution has a recess 104 extending towards the rear side wall 102, and the size and profile of the recess 104 are adapted to the knob 105. The knob 105 is fixedly installed in the recess 104. When installed, after the knob 105 is placed in the recess 104, a fastener is sequentially passed through the central shaft of the knob 105 and the bottom wall of the recess 104, thereby fixing the knob 105 in the recess 104. In use, the knob 105 rotates around the fastener to adjust the volume.
[0041] In the present embodiment, 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 is worth mentioning that the thickness direction of the knob 105 is the same as the thickness direction of the device body, i.e. the extension direction of the front side wall 101 to the rear side wall 102.
[0042] It is also understood by those skilled in the art that 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 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 the present embodiment. In the present embodiment, 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.
[0043] In addition, in the present embodiment, the width of the knob 105 is less than the width of the groove 104 adapted thereto. It is 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 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 less than the width of the groove 104, the user's fingers can easily exert a rotating force on the knob 105, thereby achieving the adjustment of the volume.
[0044] It is also understood by those skilled in the art that in other embodiments, the front side wall 101 is not provided with the groove 104, and the knob 105 is directly installed on the outer surface of the front side wall 101, which can also achieve the scheme of the present application.
[0045] In some embodiments, the device body in this solution is equipped with a pressure sensor that is in communication with the control board. The main function of the pressure sensor is 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 user's preset size, 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 this 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 combination of rotating the knob 105 and pressing confirmation, the user can more accurately control the volume while avoiding accidentally changing the set volume during the adjustment process.
[0046] 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 to the inner surface of the bottom wall of the groove 104. That is, 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, 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 likelihood of misoperation.
[0047] 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 groove wall.
[0048] 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 for indicating the reference point of volume adjustment. At the same time, the knob is equipped with scale markings such as pointers or numbers, which are used to clearly display the current volume size.
[0049] When using the handheld learning machine, the user can align the scale markings 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, 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.
[0050] In another specific embodiment, the volume adjustment mechanism of the handheld learning machine is further optimized by incorporating a pressure sensor to achieve more precise and convenient operation. Specifically, in addition to setting standard positions on the front side wall and providing scale marks on the knob to indicate the current volume size, the scheme also introduces pressure sensor technology.
[0051] When adjusting the volume, the user first aligns the desired volume scale mark by rotating the knob to 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 confirms the selected volume setting by applying pressure to the pressure sensor, which sends a pressing signal.
[0052] With this combination of visual and tactile feedback, the user can more accurately adjust and confirm the desired volume. 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 operation habits and experience, improving the practicality and user satisfaction of the handheld learning machine.
[0053] In some embodiments, the front side wall 101 of the handheld learning machine 100 has a thumb positioning area 107. Specifically, in this 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 convex to the outer surface of the front side wall 101. In addition, the front side wall 101 also has a display window 106 convex to 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 this scheme takes into account ergonomics, and such a design allows the user's thumb to be naturally placed in the thumb positioning area 107 when using the handheld learning machine 100, facilitating single-handed operation and quickly locating the knob 105 through the thumb positioning area 107 for volume adjustment, 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.
[0054] 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. This recessed design not only conforms to ergonomic principles, but also ensures that the user's thumb can be naturally placed in the recessed area when using the device, allowing quick and accurate positioning of the knob 105 for operation.
[0055] 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 is in the range of 10-20 mm. The present scheme takes into account the different habits of different users in holding the pen, and therefore introduces an adjustable thumb positioning area 107 in the design of the handheld learning machine. The area is designed to have a specific height range, aiming to meet the grip habits of different users. This design allows users to place their thumbs at different heights of the positioning area according to their comfort and preferences.
[0056] The handheld learning machine 100 of the present disclosure further comprises a speaker. Specifically, the speaker is arranged on the rear side wall 102 for voice broadcast. Specifically, the speaker is arranged opposite to the display window 106.
[0057] In a specific embodiment, the handheld learning machine 100 provided by the present disclosure is not only provided with the knob 105 on the front side wall 101, but also provided with a volume button 108 on a left side wall 103 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 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, improving the convenience of operation.
[0058] The knob 105 and the volume button 108 can work independently, i.e., control different speakers respectively, and different speakers are used for different scenarios, such as one speaker for playing the recognized text during scanning, and the other speaker for other applications of the device, such as the voice of the 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, users can choose the most suitable operation method according to their preferences and the current use scenario. For example, users 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 it is necessary to quickly adjust the volume, users can directly use the volume button 108 for operation.
[0059] In a specific embodiment, the knob 105 is cylindrical in shape. The cylindrical design conforms to the natural holding shape of the fingers, providing better grip and operation comfort, and reducing user fatigue during use.
[0060] In some embodiments, the vertical distance between the center of the knob and the end of the housing for abutting the object to be scanned is 20-40 mm. The height of the knob when the device 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 to move a large amplitude when adjusting the volume or the protruding knob blocking the user's view, nor too close to the middle area of the handheld learning machine 100 so that the height of the thumb positioning area 107 is higher. In turn, it provides a better user experience.
[0061] The handheld learning machine provided by the present disclosure can more conveniently adjust the volume and improve the user experience.
[0062] As shown in Figure 1a and Figure 1b The handheld learning machine 100 provided by the present disclosure is designed to include a cuboid-shaped body, which contains a control board inside for processing 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 part 109 are specially designed, which together constitute the scanning mechanism of the handheld learning machine 100.
[0063] Specifically, the mounting end 113 has an inclined end surface, and at least a first scanning component 111 in communication with the control board is mounted on the inclined end surface. The support part 109 is connected to the mounting end 113, 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 contacts the object to be scanned, serving as a stabilizer and support. In addition, the support part 109 is provided with a scanning window, which is aligned with the text by the user during use, so that the first scanning component 111 can capture the text information and process it.
[0064] The handheld learning machine 100 in this scheme is in a vertical state, and the end surface at the mounting end is not horizontally arranged but is inclined, and the first scanning component 111 is provided with a mounting seat, which is vertically mounted on the inclined end surface. Therefore, the first scanning component 111 is also inclined and has an angle with the horizontal plane. The purpose of this 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.
[0065] In one specific embodiment, the first scanning assembly 111 includes one first camera 111-1 and two first light supplement lamps 111-2. The first camera 111-1 is used to scan the image of the object to be scanned (e.g. text) so that the handheld learning machine can further process and recognize. The first light supplement lamps 111-2 are used in cooperation with the first camera 111-1 to provide additional light during the scanning process to ensure that the camera can capture a clear and easily recognizable image.
[0066] In one specific embodiment, the angle between the horizontally extended surface of the obliquely arranged end surface and the horizontal surface is 0-36 degrees. Such design means that the angle between the first scanning assembly 111 arranged on the end surface and the horizontal surface is also 0-36 degrees. Those skilled in the art can understand that such an angle is arranged to make it more convenient for the user to align the object to be scanned during scanning.
[0067] Compared with the conventional design in which the end surface of the mounting end 113 is parallel to the object to be scanned, the obliquely arranged end surface makes the first scanning assembly 111 more directly face the object to be scanned during use. Such design not only improves the user's comfort, but also enables a larger scanning range because the scanning assembly can be more directly aligned with the text. Therefore, the obliquely arranged end surface design not only improves the user experience, but also improves the scanning efficiency and range of the handheld learning machine.
[0068] In one specific embodiment, when the body of the handheld learning machine 100 is in a vertical state, the vertical distance between the center of the first scanning assembly 111 and the plane on which the end of the supporting part 109 away from the mounting end 113 is 15-35 mm. That is, the height of the first scanning assembly 111 in the present scheme is 15-35 mm. The height range provided by the present scheme helps to select a larger FOV (camera field of view), which can expand the scanning range. In addition, the height range in the present scheme can reduce the interference of finger or device shadow on the scanning result, and improve the accuracy of scanning.
[0069] The above scheme describes the mounting end and the first scanning assembly 111 in detail, and the structure of the supporting part 109 is described in detail as follows.
[0070] 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 housing including oppositely arranged front and rear side walls 101 and 102, and left and right side walls 103 and 103-1 connecting the front and rear side walls 101 and 102, respectively. The housing can be manufactured in one piece, which directly forms a complete housing structure through a single material or mold, ensuring the strength and integrity of the housing. On the other hand, the housing can also be assembled by individual side walls, which allows for 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 abut to form the housing. This design allows more flexible connection of the side walls, 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 the side walls in the present scheme is defined with respect to the formed body, rather than according to the manufacturing process.
[0071] 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 extends away from the mounting end 113 in the length direction and then extends 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 extends away from the mounting end 113 in the length direction and then extends 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 extends away from the mounting end 113 in the length direction and then extends perpendicularly to the extension surface of the left side wall 103.
[0072] More specifically, the extension end of the first support portion 1091, the extension 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 the present scheme is also provided with a pressure sensing assembly 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 sensing assembly can also be arranged at other positions according to actual conditions.
[0073] It is worth mentioning that the first support part 1091 in the present solution has two extending sections, one extending section extends along the length direction of the body, and the other extending section extends along the thickness direction of the body, and the connection part of the two extending sections is a smooth arc. The second support part 1092 also has two extending sections, one extending section extends along the length direction of the body, and the other extending section extends along the width direction of the body, and the connection part of the two extending sections is also a smooth arc.
[0074] In another specific embodiment, the scanning window of the handheld learning machine 100 is jointly surrounded by several specific parts, specifically including the extending end of the first support part 1091, the extending ends of the two second support parts 1092, and the end of the extending section of the rear side wall 102 of the body at the mounting end 113. One end of the extending section on the body is connected with the rear side wall 102, and the other end extends away from the mounting end 113 along the length direction.
[0075] Specifically, the rear side wall 102 of the body at the mounting end 113 is provided with an extending section, and the end of the extending section together with the ends of the first support part 1091 and the two second support parts 1092 constitutes the boundary of the scanning window. Such a design enables the extending section of the rear side wall 102 to shield the first scanning assembly 111, thereby providing physical protection for the first scanning assembly 111. This protection mechanism can effectively prevent the first scanning assembly 111 from being scratched or damaged in daily use, and ensures the stability of the scanning window and the safety of the camera module.
[0076] It is worth mentioning that in the present solution, the scanning window is designed to have a predetermined width, specifically ranging from 28mm to 43mm. This width refers to the extending direction of the left side wall 103 to the right side wall 103-1 of the body, that is, the scanning window extends 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 parts 1092 are designed to have a bracket-shaped structure. Such a 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 appearance.
[0077] In one specific embodiment, in order to avoid the end of the first support portion 1091 blocking the first scanning assembly 111, the position and shape of the first support portion 1091 are specially designed in this embodiment. Specifically, when the body of the handheld learning machine 100 is in the vertical state, the extended end of the first support portion 1091 is designed not to exceed the projection of the first scanning assembly 111 on the horizontal plane. Such design logic ensures that the first scanning assembly 111 will not be disturbed by the end of the first support portion 1091 when performing the scanning operation, thereby ensuring the smoothness of the scanning process and the accuracy of the scanning result.
[0078] As can be understood by those skilled in the art, 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 the vertical state, the end of the end face close to the scanned object is connected with the front side wall 101, and the end of the end face far from the scanned object is connected with the rear side wall 102. That is, the length of the front side wall 101 is greater than the length of the rear side wall 102 in this embodiment, and one end of the end face of the mounting end 113 is connected with the rear side wall 102, and the other end is connected with the front side wall 101. By limiting the inclination direction of the end face, the first scanning assembly 111 can better perform the scanning operation.
[0079] In some specific embodiments, as can be understood by those skilled in the art, the support portion can be integrally formed with the shell, or can be independently assembled. When the support portion is integrally formed with the shell, the first support portion is formed by continuing to extend downward from the end of the front side wall, and the two second support portions are formed by continuing to extend downward from the ends of the left and right side walls.
[0080] When the support portion is not integrally formed with the shell, the support portion and the shell are several independently arranged components, which are then fixed together by pasting or other means. At this time, in order to avoid the support portion 109 and the extension section of the rear side wall 102 blocking the content to be scanned, the support portion 109 and the extension section of the rear side wall 102 are made of transparent material in this embodiment. For example, the transparent material can be glass, plastic, etc.
[0081] In some embodiments, the handheld learning machine 100 in this 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 this 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.
[0082] 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. By carefully designing the distance between the first scanning assembly 111 and the support part 109 and the inclination angle of the first scanning assembly 111, 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 and enhance its competitiveness in the market.
[0083] It is worth noting that the structure of the support part is not limited to the shape described in this scheme, and it can have many different design forms. For example, the support part can be a structure as shown in Figure 4 and Figure 5 , which specifically includes 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 this 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.
[0084] 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.
[0085] 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 panel 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 panel 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.
[0086] In a specific embodiment, the handheld learning machine provided by the present disclosure not only includes the first scanning component 111, but also is equipped with the second scanning component 114. The second scanning component 114 is also mounted on the inclined end face at 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.
[0087] 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.
[0088] 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 present 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 scanning.
[0089] 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.
[0090] 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 111 is vertically mounted on the end face, while the mounting seat of the second scanning assembly 114 does not require vertical mounting, 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 111. Such 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.
[0091] 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.
[0092] 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 scanning.
[0093] Therefore, in the present solution, the distance between the centers of the first scanning assembly 111 and the second scanning assembly 114 is set in the range of 9-35 mm. Such a design not only ensures that there is enough distance between the two cameras to avoid too large a repeated scanning area, but also ensures that the distance between them is not too far, thereby avoiding the problem of missing scanning content.
[0094] It is worth noting that, Figure 1b Figure 3 The drawings are specifically used to show the layout of the first scanning assembly and the second scanning assembly on the end face of the mounting end of the handheld learning machine. These drawings specifically depict the relative positions and mounting methods of the two scanning assemblies in order 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.
[0095] As can be understood by those skilled in the art, the type of 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.
[0096] The handheld learning machine 100 provided by the present disclosure, due to the provision of the first scanning assembly 111 and the second scanning assembly 114, and the installation of both on the obliquely arranged end face, such a double scanning assembly configuration not only covers a larger text area, but also reduces the number of user operations during scanning, improving the overall user experience.
[0097] As Figure 1a shown, in some embodiments of the present disclosure, the end of the device body opposite the mounting end has a protrusively arranged microphone 115, which is in communication connection with the control board.
[0098] The handheld learning machine 100 provided by the present disclosure, by providing a microphone 115 on the end opposite the scanning end, not only facilitates the user to aim the mouth during voice interaction, but also ensures the clarity and accuracy of voice input. The user does not need to frequently adjust the device direction during use, but only needs to simply move the device to the mouth to perform smooth voice input, whether it is to query the pronunciation of a word, to learn a language, or to have a conversation with the device, it can be easily completed. Such an integrated design not only optimizes the user's operation process, but also enhances the functionality of the device, improving the user's experience.
[0099] In a specific embodiment, the microphone 115 is a directional microphone 115.
[0100] The microphone 115 in the present solution is a directional microphone 115, which can not only capture sound from a specific direction more effectively, but also reduce background noise and sound interference from the side or back, thereby improving the clarity of the voice. By capturing sound from a specific direction only, the microphone 115 can also reduce the unintended capture of other people's conversations, thereby improving privacy protection.
[0101] In a specific embodiment, the microphone 115 includes a cylindrical shell, one end of which is connected to the device body, and the other end extends away from the device body along the length direction; the other end has an end face, and the end face is provided with a microphone hole.
[0102] The microphone 115 in the present solution has a cylindrical shell, which has two ends in the length direction, one end is connected to the device body, and the other end extends away from the device body along the length direction. In addition, the other end of the shell has an end face, and the end face has a plurality of uniformly arranged microphone holes.
[0103] The microphone 115 provided in the present solution can ensure that sound enters the microphone 115 uniformly from multiple angles due to the uniformly distributed microphone holes on the end face, which helps to improve the efficiency and uniformity of sound capture, especially in scenarios where stereo or surround sound needs to be captured.
[0104] As can be understood by those skilled in the art, in other embodiments, microphone holes can also be provided not only on the end face but also on the peripheral wall of the shell.
[0105] As can be understood by those skilled in the art, the shell of the microphone 115 can also not be a regular cylindrical shape. The specific shape can be set according to different needs. For example, the shell of the microphone 115 can be designed to be composed of four peripheral walls connected to each other, which provides more flexibility and stability in structure. In order to enhance the aesthetics and reduce stress concentration in the production process, the peripheral walls are chamfered at the connection, making the curved surface of the connection smoother.
[0106] In a specific embodiment, the device body includes an upper end wall 110 having a predetermined length and a predetermined width, and the microphone 115 is arranged at the center position of the upper end wall 110.
[0107] In the present solution, the device 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 predetermined length and a predetermined width, and the microphone 115 is arranged at the center position of the upper end wall 110.
[0108] In one specific embodiment, the device body includes an upper end wall 110 having a preset length and a preset width, and the microphone 115 is disposed at a region between the center of the upper end wall 110 and any one edge of the length direction of the upper end wall 110. It is worth mentioning that the length direction of the upper end wall in this scheme refers to the width direction of the device body, and the width direction of the upper end wall refers to the thickness direction of the device body.
[0109] In this scheme, the device 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 the two ends of the length direction, respectively. The microphone 115 can be disposed between the center of the upper end wall 110 and the first edge of the length direction of the upper end wall 110, or between the center of the upper end wall 110 and the second edge of the length direction of the upper end wall 110. When the device 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 scheme is not disposed along the center line but offset from the center line.
[0110] In one specific embodiment, the upper end wall 110 further has a protruding connector 116 disposed thereon, and the connector 116 further has a through hole disposed thereon, wherein the extension direction of the through hole is perpendicular to the protruding direction of the connector 116.
[0111] The microphone 115 is disposed at a region between the center of the upper end wall 110 and one edge of the length direction of the upper end wall 110, and the connector 116 is disposed at a region between the center of the upper end wall 110 and the other edge of the length direction of the upper end wall 110.
[0112] In this scheme, the upper end wall 110 of the device body not only has a protruding microphone 115 disposed thereon, but also has a protruding connector 116 disposed thereon. The microphone 115 is disposed at a region between the center of the upper end wall 110 and one edge of the length direction of the upper end wall 110, and the connector 116 is disposed at a region between the center of the upper end wall 110 and the other edge of the length direction of the upper end wall 110. This layout means that when the device 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 device body and symmetrically distributed at the two ends of the length direction.
[0113] In addition, the connector 116 further has a through hole disposed thereon, and the extension direction of the through hole is perpendicular to the protruding direction of the connector 116, that is, when the device body is placed vertically, the protruding direction of the connector 116 is consistent with the device body, that is, in a vertical direction, and the through hole extends horizontally. This design allows the hanging rope to pass through the through hole, so that it can be fixed with the handheld learning machine 100, and then the hanging rope can be conveniently hung on the user's neck.
[0114] The present solution increases the portability and practicality of the device by providing a through hole on the connecting piece 116. When the user needs to carry the device, he can directly put the lanyard around his neck, thus freeing his hands and improving the convenience of use. In addition, this design also helps to prevent the device from being accidentally dropped or lost during carrying, enhancing the safety of the device.
[0115] In a specific embodiment, the connecting piece 116 and the microphone 115 are symmetrically arranged along the center of the upper end wall 110. Specifically, the connecting piece 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 mirror-symmetrically arranged with respect to the center line of the device body. This symmetrical layout not only provides a balanced and harmonious visual beauty, but also helps to disperse the weight of the device, making it more stable and comfortable to use.
[0116] In a specific embodiment, the size and shape of the connecting piece 116 are the same as those of the microphone 115. That is, the microphone 115 and the connecting piece 116 are not only symmetrically arranged in position, but also consistent in shape and size. This design means that the microphone 115 and the connecting piece 116 present a mirror-symmetric layout in appearance, and they are uniformly distributed along the center line of the upper end wall 110 and are completely identical in size and shape. Such consistent design provides a unified and coordinated visual impression, enhancing the overall aesthetic appearance of the device.
[0117] The handheld learning machine 100 provided by the present disclosure, by providing a microphone 115 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, improving the user's experience.
