[0002] The interactive smart tablet integrates touch, display and information processing functions, and is an all-in-one device that can realize human-computer interaction.

[0003] Interactive smart tablets typically have an antenna for transmitting and receiving wireless signals. In related art, the antenna is located on the bottom frame of the device. This antenna is affected by the bottom frame and the functional modules of the interactive smart tablet, causing interference with the antenna signal and affecting the user experience.

[0004] Summary of the Invention

[0005] An embodiment of the present application provides an interactive smart tablet that can reduce the loss of wireless signals in front of the screen.

[0006] The present invention provides an interactive smart tablet, which includes:

[0007] An upper frame, wherein a side of the upper frame facing the observer is provided with an escape opening;

[0008] a microphone module, the microphone module comprising a circuit board and a microphone body, the circuit board being disposed within the upper frame and having a mounting area positioned opposite to the avoidance opening, the microphone body being disposed on the circuit board; and

[0009] An antenna is provided in the installation area and located within the upper frame, and the antenna radiates signals toward the front of the upper frame.

[0010] In the interactive smart tablet based on the embodiment of the present application, the main radiation direction of the antenna is toward the front of the frame, and the performance of transmitting interactive signals in front of the screen is better. The antenna can send and receive wireless signals through the avoidance opening. When sending and receiving wireless signals, it is less affected by the screen, ground or wall, etc., and the signal loss is less. It can achieve more ideal wireless signal transmission in front of the screen and improve user experience.

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solutions and advantages of this application clearer, the following part will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0048] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application, as detailed in the appended claims.

[0049] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, in the description of this application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0051] The interactive smart tablet integrates touch, display and information processing functions, and is an all-in-one device that can realize human-computer interaction.

[0052] As can be understood, an interactive smart tablet consists of a screen and a back panel. The screen integrates display and touch functions, while the back panel provides structural support and carries components such as the backlight module. Interactive smart tablets typically have an antenna for transmitting and receiving wireless signals and a main control chip for processing information. The main control chip interacts with the antenna and processes the signals accordingly.

[0053] Furthermore, compared to electronic devices such as mobile phones and laptops (mobile phones and laptops are also equipped with antennas), interactive smart tablets have very different usage scenarios. For example, when using mobile phones and laptops, users often hold the above electronic devices and operate them directly (referring to directly touching the above electronic devices). This causes the antennas of the above electronic devices to be within a fixed range when receiving signals. Therefore, when installing antennas for mobile phones, laptops and other devices, there is no need to consider the radiation interference of electronic devices on the antenna or the radiation loss caused by the antenna assembly direction. However, in addition to conventional touch operations, interactive smart tablets will be used in large spaces such as classrooms and conference rooms. Therefore, when the interactive smart tablet receives signals, the distance at which the antenna receives the signal is farther than that of electronic devices such as mobile phones and laptops. Therefore, in order to ensure the signal reception effect of the antenna, the interactive smart tablet will continuously adjust the antenna itself.

[0054] Currently, interactive smart tablets process wireless signals such as WIFI and Bluetooth by installing antennas. Some interactive smart tablets place the antenna on the back panel behind the screen (the antenna module is often electrically connected to the circuit board or mainboard through plugging). Since the antenna module needs to receive signals through the screen, the antenna will suffer losses when receiving signals.

[0055] Some interactive smart tablets choose to install the antenna in the bottom bezel to prevent the antenna from processing signals through the screen. After the antenna is installed in the bottom bezel, a slit is created on the side facing the viewer to allow the antenna to pass through the slit to receive or radiate digital signals forward. However, due to the complex internal wiring of the bottom bezel of interactive smart tablets and the proximity of the TCON board, source board, and main board, antennas installed in the bottom bezel can be subject to signal interference.

[0056] To address the above issues, referring to FIG1 , this application proposes an interactive smart tablet 100 for mounting on a wall or a stand to display relevant information and enable interaction. In an embodiment of this application, the interactive smart tablet 100 includes a frame 10 , a screen (not shown), a microphone module 30 , a connecting bracket 50 , a mainboard 40 , and a shielding cover 70 .

[0057] In the embodiment of the present application, the screen is mounted on the frame 10. Please refer to Figure 1 for details. Figure 1 is a schematic diagram of the overall structure of the interactive smart tablet 100 in the embodiment of the present application. For the convenience of description, the side of the interactive smart tablet 100 facing the observer is called the front side, and oppositely, the side facing away from the observer is called the back side. Viewed from the front, the frame 10 is arranged along the periphery of the interactive smart tablet 100, and the frame 10 is roughly a closed ring structure, thereby defining a window area 10a in the middle. The display area of ​​the screen is arranged at the window area 10a to display text, patterns and other content through the window area 10a. It can be understood that the frame 10 can be a whole or can be made up of several separate panels. The window area 10a defined by it can be circular, square or other shapes, and this embodiment does not impose too many restrictions on this.

[0058] Please refer to Figure 2, which is a schematic diagram of a partial structure of the frame 10. As shown in the figure, the frame 10 is provided with a avoidance opening 111b. The avoidance opening 111b is opened toward the front of the frame 10, so that when the avoidance opening 111b is observed from the front, the interior of the frame 10 or part of the structure on the back of the frame 10 can be seen through the avoidance opening 111b. The shape of the avoidance opening 111b is not required and can be circular or square. Please refer to Figure 3, which is a schematic diagram of the partial structure of the back of the frame 10 corresponding to Figure 2. The back of the frame 10 forms a certain space to accommodate the relevant structure.

[0059] Interactive smart tablets 100 often need to be equipped with a microphone module 30 to achieve sound interaction. The microphone module 30 includes a circuit board 31 and a microphone body 33, and the microphone body 33 is arranged on the circuit board. In order to ensure the sound reception effect and facilitate installation, the microphone body 33 is arranged on the surface of the circuit board 31 away from the avoidance opening 111b, and the circuit board 31 is provided with a microphone hole 30a that passes through the circuit board 31 in the thickness direction, and the microphone body 33 is connected to the microphone hole 30a. Multiple microphone bodies 33 can be arranged on the circuit board 31, and the multiple microphone bodies 33 are arranged at intervals along the extension direction of the board surface. Correspondingly, the circuit board 31 is provided with multiple microphone holes 30a that correspond one to one with the microphone bodies 33. In order to further improve the sound reception effect, the microphone body 33 is also covered by a shielding cover.

[0060] In one embodiment, for the interactive smart tablet 100, after the microphone module 30 is installed on the upper frame 11, a certain amount of space will be left for the circuit board 31 in the upper frame 11 (a gap is left between the two long sides of the circuit board 31 and the two sides of the upper frame 11 along the direction of gravity). Therefore, when the antenna 35 is installed on the circuit board 31 in this application, the circuit board 31 can be adaptively widened in advance according to the structure and size of the antenna 35 to ensure that the antenna 35 can be installed on the circuit board 31. In addition, because only the circuit board 31 is widened, only the size of the board surface of the circuit board 31 is increased, and the electronic structure on the circuit board 31 is not changed. Therefore, installing the antenna 35 on the circuit board 31 will not affect the electronic structure of the circuit board 31.

[0061] Furthermore, the circuit board 31 is provided with a mounting area opposite to the avoidance opening 111b, and the mounting area is used to install the antenna 35. It is understandable that the mounting area can be part or all of the area on the circuit board 31, and the embodiment of the present application does not limit this.

[0062] Referring to Figures 3 and 4 , the circuit board 31, connecting bracket 50, mainboard 40, and shielding cover 70 are all located within the frame 10. The mainboard 40 is used for data processing and structural control. A radio frequency chip is integrated into the circuit board 31 or mainboard 40. This chip is capable of converting radio frequency signals into digital signals. The antenna 35 is electrically connected to the radio frequency chip, which is in communication with the mainboard 40. The antenna 35 transmits signals, or feeds signals received by the antenna 35 back to the mainboard 40, thereby enabling wireless interaction.

[0063] It is understandable that in the embodiment of the present application, the avoidance opening 111b can be opened at any point on the circumference of the window area 10a. In the common interactive smart tablet 100, considering the ultra-narrow frame design of the interactive smart tablet 100, the frames 10 on both sides are designed to be narrowed. At the same time, as the frames 10 on both sides become narrower, the power board, touch frame board, buttons, data interface and other components required for the interactive smart tablet 100 will be integrated into the lower frame 10. On this basis, the narrowed frames 10 on both sides are difficult to support the opening of the avoidance opening 111b on its surface; if the avoidance opening 111b is opened in the lower frame 10, on the one hand, because there are more components in the lower frame 10, it is easy to affect the signal; on the other hand, too many components piled on the lower frame 10 will also make the width of the lower frame 10 too large, causing certain damage to the aesthetics and reducing the competitiveness of the product.

[0064] Exemplarily, the frame 10 is arranged in a ring shape, the avoidance opening 111 b is arranged in the upper half of the frame 10 , and the antenna 35 is arranged inside the frame 10 .

[0065] Please refer to Figure 1 again. In some embodiments of the present application, the frame 10 includes an upper frame 11, a lower frame 13, and at least two side frames 15. The at least two side frames 15 are arranged at intervals. One end of each side frame 15 is connected to the upper frame 11, and the other end is connected to the lower frame 13. The upper frame 11, the lower frame 13, and the at least two side frames 15 enclose a window area 10a. Optionally, the upper frame 11, the lower frame 13, and the at least two side frames 15 are all arranged in a strip shape and enclose a square window area 10a, wherein the upper frame 11, the lower frame 13, and the at least two side frames 15 can be an integrated structure, or can be independently formed and then assembled. The avoidance opening 111b is provided on the upper frame 11, and the antenna 35 is provided in the upper frame 11.

[0066] Please refer to Figure 2 again. The upper frame 11 includes a front panel 111 and a side mounting portion 113. The front panel 111 is a plate-like structure on the upper frame 11 facing the front side. The front panels 111 at various locations on the upper frame 11 enclose and form the window area 10a. The side mounting portion 113 is connected to the outer side of the front panel 111, that is, the side of the front panel 111 away from the window area 10a, and extends in a direction away from the front panel 111. The side mounting portion 113 can provide certain structural support to the front panel 111, and its inner surface is also used to form an inner wall of the internal space of the upper frame 11.

[0067] As shown in FIG2 , the avoidance opening 111 b is provided on the front panel 111 , and the antenna 35 is provided on the back side of the front panel 111 . The antenna 35 can directly transmit and receive wireless signals through the avoidance opening 111 b , and has better signal transmission performance.

[0068] Unlike the side-mounted portion 113 in FIG. 2 , which is arranged at a substantially right angle (90°±5°) to the front panel 111, referring to FIG. 5 to FIG. 7 , in another embodiment, the side-mounted portion 113 extends obliquely relative to the front panel 113 in a direction away from the window area 10a. Viewed from the front, the side-mounted portion 113 forms a slope structure located outside the front panel 111. Taking the upper frame 11 as an example, as shown in FIG. 5 , the side-mounted portion 113 can be formed by the top panel of the upper frame 11 extending toward the rear side and also toward the upper side, so that the side-mounted portion 113 forms a slope structure. In this form, the avoidance opening 111b is opened in the side-mounted portion 113, or as shown in FIG. 6 , the avoidance opening 111b extends from the side-mounted portion 113 to the front panel 113, and the opening of the avoidance opening 111b can still face directly forward. Then, as shown in FIG. 7 , the antenna 35 can be located within the slope structure so that it can also radiate signals directly forward through the avoidance opening 111b on the side-mounted portion 113. In this way, while satisfying the forward radiation requirement of the antenna 35 , the material and space of the front panel 111 can be saved to a certain extent.

[0069] In the embodiment of the present application, the antenna 35 is disposed within the upper frame 11 and exposed at the avoidance opening 111b to radiate signals toward the front of the frame 10. In this way, the main radiation direction of the antenna 35 is toward the front of the frame 10, and the performance of transmitting interactive signals in front of the screen is better. The antenna 35 can transmit and receive wireless signals through the avoidance opening 111b, and is less affected by the screen, ground, or wall when transmitting and receiving wireless signals, resulting in less signal loss, which can achieve more ideal wireless signal transmission in front of the screen and improve the user experience.

[0070] Moreover, based on installation requirements, the interactive smart tablet 100 will consider the structure of the microphone module 30 when designing the structure of the frame 10. At the same time, the microphone module 30 will be installed on the upper frame 11 to ensure that the upper frame 11 can effectively install the corresponding microphone module 30. In this application, the antenna 35 is integrated with the circuit board 31 of the microphone module 30. For example, the chip and wiring of the antenna 35 can be directly installed on the front and back of the circuit board 31. Because the chip itself has a small structure and the wiring is more flexible, it is very easy to integrate the antenna 35 with the circuit board 31. When the antenna 35 is installed on the interactive smart tablet 100, there is no need to consider the adaptation problem between the antenna 35 and the frame 10 (that is, the frame 10 does not need to be adjusted due to the antenna 35 itself). In addition, due to the sound pickup requirements of the microphone module 30, the microphone module 30 will face the observer after being installed on the upper frame 11 (that is, the microphone module 30 is set forward), so the microphone module 30 will not change the original assembly method when integrating the antenna 35, the modification cost is low, and it is easy to assemble.

[0071] Specifically, referring to Figures 8 and 9 , the antenna 35 and microphone module 30 can be arranged on the circuit board 31 in a spaced arrangement from bottom to top or from top to bottom along the direction of gravity of the interactive smart tablet 100. For example, the upper portion of the circuit board 31 is provided with structures such as the microphone body 33, the plug hole 30b, and the power supply interface 53, and the lower portion is provided with the antenna 35. The antenna 35 is the area framed by the dotted line in Figure 8 and is located on the side of the circuit board 31 facing the avoidance opening 111b or the side facing away from the avoidance opening 111b. The antenna 35 and microphone module 30 can also be arranged on the circuit board 31 in a spaced arrangement along the horizontal direction of the interactive smart tablet 100, that is, the left and right direction from the observer's perspective; alternatively, the microphone module 30 can be set at any position outside the installation area.

[0072] It is understood that multiple antennas 35 can be installed on a single circuit board 31, with the multiple antennas 35 spaced apart. For example, an antenna 35 can be installed between two adjacent microphone holes 30a, and two antennas 35 can be installed on each circuit board 31. In this way, integrating the functions of the antenna 35 and the microphone on a single circuit board 31 saves space and materials, and facilitates assembly of the antenna 35 and the microphone body 33.

[0073] The upper frame 11 is further provided with a plurality of through holes communicating with the microphone hole 30a, allowing sound to pass through the through holes and the microphone hole 30a and be captured by the microphone body 33. Alternatively, the microphone hole 30a is connected to the avoidance opening 111b. To ensure sound reception, as shown in FIG9 , the circuit board 31 is further provided with a sealing foam having a shape and size similar to that of the avoidance opening 111b.

[0074] As shown in FIG9 , in one embodiment, a conductive foam 36 is further provided on the surface of the circuit board 31 facing the avoidance opening, and a laser-engraved area is provided on the inner wall surface of the upper frame 111 corresponding to the conductive foam 36 . The conductive foam 36 abuts against the laser-engraved area, which can improve the consistency of the antenna 35 .

[0075] Please refer to Figure 4 again. The circuit board 31 is arranged in the upper frame 11 and is arranged in the position of the avoidance opening 111b. Optionally, the circuit board 31 and the frame 10 can be directly connected by screws. In the embodiment of the present application, the upper frame 11 is provided with a hollow area corresponding to the connecting bracket 50, and at least part of the connecting bracket 50 is arranged in the hollow area. Referring to Figure 10, the two ends of the connecting bracket 50 can be connected to the upper frame 11 by bolts or snaps, etc., which is not required here. The connecting bracket 50 is provided with a first connecting portion 51 corresponding to the position of the circuit board 31 and a second connecting portion 53 corresponding to the position of the main board 40. The first connecting portion 51 and the second connecting portion 53 are arranged along the extension direction of the upper frame 11, wherein the first connecting portion 51 and / or the second connecting portion 53 can be connected to the upper frame 11 by bolts or snaps. The circuit board 31 is installed on the side of the first connecting portion 51 facing the avoidance opening 111b.

[0076] Optionally, the first connecting portion 51 is formed with a plurality of first clips for clipping onto the edge of the circuit board 31, thereby securing the circuit board 31 to the connecting bracket 50. The clipping method makes assembly and disassembly more convenient. Furthermore, the circuit board 31 is provided with a plug hole 30b, and the first connecting portion 51 also includes a plug post, which plugs into and mates with the plug hole 30b. This not only facilitates installation and positioning, but also increases constraints, thereby improving the stability and reliability of the connection of the circuit board 31 to the first connecting portion 51. The main board 40 is disposed on the side of the second connecting portion 53 facing away from the avoidance opening 111b. The second connecting portion 53 is formed with a plurality of second clips for clipping onto the edge of the main board 40, thereby securing the main board 40 to the connecting bracket 50. Of course, the first connecting portion 51 and the second connecting portion 53 may also be secured using other methods, such as bolt connections, which are not limited in this application.

[0077] Power and signal transmission are carried out between the circuit board 31 and the mainboard 40 via a flat cable 41. The RF chip can be integrated into the mainboard 40 and communicate with the antenna 35 on the circuit board 31 via the flat cable 41, saving space on the circuit board 31 and facilitating the wiring of the antenna 35. In another embodiment, the RF chip can also be located on the circuit board 31 and electrically connected directly to the antenna 35, thereby reducing the number of wires between the mainboard 40 and the circuit board 31, facilitating structural layout, reducing the space occupied by the frame 10, and facilitating the arrangement of other components.

[0078] In the embodiment of the present application, the shielding cover 70 can be made of plastic material. The shielding cover 70 is arranged on the side of the connecting bracket 50 away from the avoidance opening 111b and is connected to the frame 10 to at least shield the mainboard 40 and play a protective shielding role.

[0079] Further, please continue to refer to Figures 4 and 10. In the embodiment of the present application, the frame 10 is also provided with a camera hole 111c. The camera hole 111c and the avoidance opening 111b are located on the same side of the upper frame 11. The interactive smart tablet 100 also includes a camera module 80, which is arranged side by side with the circuit board 31 left and right or up and down, and at least part of the camera module 80 is exposed in the camera hole 111c to capture image information through the camera hole 111c, making the interactive mode of the interactive smart tablet 100 more diverse. The camera module 80 includes a camera bracket 81 and a camera body installed on the camera bracket 81. The camera bracket 81 is connected to the side of the second connecting portion 53 facing the avoidance opening 111b. Among them, the second connecting portion 53 and the camera bracket 81 can be connected by one or more connection methods such as snap-on, plug-in, and bolt connection, and this application does not limit this. The camera body and the main board 40 are connected to each other through a signal line, and the camera module 80 and the main board 40 are arranged on both sides of the second connecting part 53 to facilitate wiring and structural layout.

[0080] The avoidance opening 111b is centrally located on the upper frame 11. Specifically, referring to Figures 1 and 2, the camera hole 111c is centrally located on the upper frame 11 to provide the camera module 80 with a good shooting angle. Optionally, the frame 10 is provided with a avoidance opening 111b, which is adjacent to the camera hole 111c, and the avoidance opening 111b and the camera hole 111c are arranged side by side in the longitudinal direction of the upper frame 11. The circuit board 31 is located inside the avoidance opening 111b, and the antenna 35 is exposed from the avoidance opening 111b. This can minimize the width of the upper frame 11.

[0081] Furthermore, to fully satisfy wireless signal interaction, the upper frame 11 is provided with at least two avoidance openings 111b, located on opposite sides of the camera hole 111c. If the number of avoidance openings 111b is even, they are symmetrically arranged with respect to the camera hole 111c, improving the aesthetics. Referring to FIG3 , the interactive smart tablet 100 accordingly includes at least two circuit boards 31, located on opposite sides of the camera hole 111c. The connecting bracket 50 is provided with a first connecting portion 51 corresponding to each circuit board 31. Each circuit board 31 is provided with at least one antenna 35, so that one antenna 35 is exposed at a avoidance opening 111b. The multiple antennas 35 can provide better signal transmission performance.

[0082] In an optional embodiment of the present application, the frame 10 is made of metal. For example, the frame 10 can be made of aluminum alloy through an extrusion molding process, which is relatively easy to process and produce, and has high strength. Referring again to Figure 2, as one possible structural form, the frame 10 is a box-type structure with a hollow interior. While ensuring considerable strength and good protection, it provides ample internal space to facilitate the arrangement of devices. The avoidance opening 111b is connected to the internal space, and the antenna 35 is arranged relative to the avoidance opening 111b, so that the signal can be radiated toward the front of the frame 10 through the avoidance opening 111b.

[0083] At the same time, to prevent foreign matter from entering the internal space of the frame 10 through the avoidance opening 111b and affecting the normal use of the internal structure, please refer to Figure 4. This embodiment of the application also has a plastic shielding member 90. The plastic shielding member 90 is provided in front of the upper frame 11 to shield the avoidance opening 111b. Optionally, the plastic shielding member 90 can be a Mylar sheet, which is connected to the outer periphery of the avoidance opening 111b by gluing or other means to achieve shielding of the avoidance opening 111b. Furthermore, the Mylar sheet is the same or similar color as the upper frame 11 to enhance the overall appearance.

[0084] The plastic shielding member 90 is provided with a plurality of sound pickup holes 90 a , which are connected to the plurality of microphone holes 30 a in a one-to-one correspondence to ensure a good sound pickup effect.

[0085] It should be noted that to ensure the proper functioning of the camera module 80, the plastic shielding member 90 is transparent. Alternatively, in some embodiments, the plastic shielding member 90 is provided with a clearance opening 90b corresponding to the camera head of the camera module 80, and a shielding sheet 91 is provided at the clearance opening 90b to achieve a combination of shielding members made of two different materials according to actual conditions, thereby ensuring the proper functioning of the camera module 90.

[0086] Furthermore, in other embodiments, in order to make the front surface of the upper frame 11 smoother, a groove 111a is provided on the outer surface of the upper frame 11, and an avoidance opening 111b is provided on the bottom wall of the groove 111a. In this embodiment, the antenna 35 and the microphone body 33 are both integrated on the circuit board 31. If the microphone module 30 and the antenna 35 are arranged side by side, the structural span of the circuit board 31 in the longitudinal direction of the upper frame 11 is larger. Correspondingly, the length of the groove 111a is longer, and a longer plastic shielding member 90 is also required. Therefore, the antenna 35 and the microphone module 30 can be arranged on the circuit board 31 at intervals in the vertical direction. In this way, the structural span of the circuit board 31 in the longitudinal direction of the upper frame 11 is not too long, and the plastic shielding member 90 is shorter, which can save materials and also make the front appearance of the interactive smart tablet 100 more harmonious and more beautiful.

[0087] Optionally, the groove 111 a is configured to be waist-shaped, and the shape of the plastic shielding member 90 is adapted to the shape of the groove 111 a , further improving the aesthetics.

[0088] Of course, the frame 10 can also be made of plastic material, which has good toughness.

[0089] In a possible embodiment of the present application, the upper frame 11 is designed as a three-section type. Along the extension direction of the upper frame 11, the middle part is a plastic section and the two sides are metal sections. The plastic section and the metal section are fixedly connected by bonding or by fasteners such as bolts. In this embodiment, the antenna 35, the microphone module 30 and the camera module are all arranged inside the plastic section. The plastic section is provided with an avoidance opening 111b, a camera through hole 111c and a plurality of through holes connected to the microphone hole 30a. In this way, the plastic section has little effect on the signal radiation of the antenna 35, and there is no need to provide a groove 111a in the plastic section of the upper frame 11 and set a plastic shielding member 90 in the groove 111a, which makes the appearance more neat.

[0090] In one embodiment, a conventional interactive smart tablet 100 is wall-mounted, and the signal from antenna 35 is largely absorbed and lost by the wall, further attenuating the signal. In this application, antenna 35 is mounted on top frame 11, with the receiving (or radiating) surface of antenna 35 (referring to the side of antenna 35 that receives digital signals) facing directly toward the viewer. This prevents antenna 35 from radiating toward the surrounding wall, thereby preventing interference from the wall with the antenna signal.

[0091] In one embodiment, antenna 35 may be hidden between the screen and the back panel. Since the screen is located in front of antenna 35, the forward radiation will be partially absorbed and blocked by the shield, resulting in severe signal attenuation. In this application, antenna 35 is installed on the upper frame 11, and the receiving (or radiating) surface of antenna 35 (referring to the side of antenna 35 that receives digital signals) directly faces the observer, avoiding signal shielding of antenna 35 by the screen.

[0092] In addition, it should be noted that the antenna 35 itself is integrated with the circuit board 31, the chip, etc., and is directly exposed to the outside of the interactive smart tablet 100, which will directly damage the antenna 35. Therefore, the above assembly method is not advisable. Furthermore, when using an antenna box for assembly, if the antenna box is installed on the periphery of the interactive smart tablet 100, the antenna receiving line (or antenna receiving post) of the antenna box will be exposed outside the periphery of the interactive smart tablet 100. This will directly affect the assembly of the interactive smart tablet 100 in most scenarios, including: in a conference room where the interactive smart tablet 100 needs to be embedded in the wall, or in a classroom where the interactive smart tablet 100 needs to be embedded in the blackboard. Therefore, the above assembly method is also not advisable.
