Description

TECHNICAL FIELD

[0001] The present application relates to a human-computer interaction device for multiple people, in particular to a double-screen interaction device. BACKGROUND

[0002] In some scenarios, one party is an information obtaining party and the other party is an information providing party. The information obtaining party guides and obtains the language information, paper information, electronic information and other information of the information providing party, and then makes a judgment on the basic situation of the information providing party or provides relevant services for the information providing party after comprehensively sorting the information. The above-mentioned scenarios may occur in hospitals, banks, government service departments and the like, but are not limited thereto.

[0003] In order to be fast and convenient, an interaction device can be used to assist in completing the above-mentioned information interaction. The interaction device can guide the information providing party to provide corresponding information, including but not limited to voice information, paper information and electronic information and the like.

[0004] The interaction device generally includes two screens, and the relative positions of the two screens are fixed. Generally, the two screens are arranged opposite to each other. One screen is used by the information obtaining party, such as a doctor, a bank clerk, a staff member and the like. The other screen is used by the information providing party, such as a patient, a bank user, a person doing business and the like. The two users of the interaction device face their respective screens. Since the positions of the screens are fixed, the relative positions cannot be changed according to the actual space situation or personal use habits. In addition, when the interaction device obtains the language information of the user, it needs to clearly distinguish the identity of the speaker. Otherwise, it will lead to confusion in the language information input, affecting the efficiency and effect of doing business.

[0005] Therefore, there is an urgent need for a double-screen interaction device that can assist both parties. In the design of the double-screen interaction device, the need for the two users to change the relative positions according to the actual space situation or personal use habits and the like needs to be considered. In addition, even if the relative positions change, the double-screen interaction device can always clearly distinguish the identity of the speaker, which can ensure the efficiency and effect of doing business. SUMMARY

[0006] In view of the above problems, the present application discloses a double-screen interaction device. The device includes a rotatable screen, which can change the relative positions of the two parties according to the actual space situation or personal use habits and the like, meet the needs of the two parties to interact in different interaction positions, and is designed with a ring-shaped microphone array device that can rotate with the rotating screen, so that it can always accurately distinguish the identity of the speaker, ensuring that the information obtained by the two parties during the interaction is more efficient and reliable.

[0007] In order to achieve the above-mentioned purposes, the present application adopts the following technical solutions: The application provides a double-screen interactive device, which comprises a base, a first screen and a second screen. The top of the base is provided with a rotating shaft arranged along the height direction. The first screen is arranged on one side of the base. The back of the second screen is provided with a connecting arm, and the second screen is connected to the side surface of the rotating shaft through the connecting arm. The rotating shaft is internally provided with a ring-shaped microphone array device which rotates together with the rotating shaft. The microphone units of the ring-shaped microphone array device are arranged in uniform intervals around the axis of the rotating shaft. The top end surface of the rotating shaft is provided with sound pickup holes corresponding to the microphone units. The microphone units in the ring-shaped microphone array device are divided into at least two groups of microphone units, and one group of microphone units is arranged corresponding to the orientation of the second screen.

[0008] The device comprises a double-screen structure, wherein the second screen can rotate around a rotating shaft to change the relative position between the first screen and the second screen, thereby meeting the demand that the two parties of interaction can be in different interaction positions for interaction. If necessary, the interaction position can also be changed at any time during the interaction process, thereby avoiding the single and fixed interaction position. The device is further provided with a ring-shaped microphone array device in the rotating shaft. The microphone units constituting the ring-shaped microphone array device rotate around the same axis and follow the rotating shaft. Part of the microphone units constitute a group of microphone units and are arranged corresponding to the orientation of the second screen. That is, during the rotation of the rotating shaft, the relative position between the microphone group and the second screen is always unchanged. Regardless of the rotation of the second screen, the orientation relationship between the microphone group and the orientation where the user of the second screen emits sound remains relatively unchanged. This design allows the algorithm system inside the device to only need to determine whether a specific orientation of the microphone group corresponding to the second screen has sound emitted. As long as the orientation has sound emitted, it can be determined that the sound is possibly emitted by the user of the second screen. Therefore, the algorithm process is greatly simplified, and the corresponding speed and positioning accuracy are improved.

[0009] In one illustrative embodiment of the dual-screen interactive device, the rotating shaft includes a rotating shaft body and an end cap. The top of the rotating shaft body has an installation space, and the end cap can be fitted onto the rotating shaft body to close the installation space. The outer surface of the end cap forms a top end face with a microphone hole. The ring-shaped microphone array device includes a microphone circuit board, several sealing rings disposed between the microphone circuit board and the end cap, and a ring-shaped mounting bracket. The microphone circuit board integrates several microphones corresponding to the microphone holes. The sealing rings are located between the corresponding microphones and the microphone holes. The ring-shaped mounting bracket forms receiving slots corresponding to each microphone, and each receiving slot contains a sealing sleeve. The ring-shaped mounting bracket can clamp and assemble the microphone circuit board to the end cap, so that each receiving slot, sealing sleeve, microphone, and sealing ring constitutes a microphone unit. This arrangement of the ring-shaped microphone array device within the rotating shaft ensures that the microphone group in the ring-shaped microphone array device can rotate with the second screen. The sealing rings and sealing sleeves in the microphone unit ensure that the microphone is in a sealed space, shielding it from ambient noise and enabling it to accurately receive and record the operator's voice information.

[0010] In one illustrative embodiment of the dual-screen interactive device, the rotating shaft also includes two arc-shaped lights. The assembled end cap can hold the arc-shaped lights between the rotating shaft body and the end cap, and each arc-shaped light corresponds to a microphone group. This design allows the two arc-shaped lights to correspond to the speakers on the first screen and the second screen, respectively. That is, when the dual-screen interactive device determines that the speaker on the second screen is speaking, its corresponding arc-shaped light will light up; if it determines that the speaker on the first screen is speaking, the arc-shaped light corresponding to the first screen will light up. This prompts the speaker that their voice information is being received by the device, ensuring that the operator can promptly confirm whether their voice information is being received and recorded during the output of voice information.

[0011] In one illustrative embodiment of the dual-screen interactive device, the height of the top end face of the rotating axis is higher than the height of the first screen and the height of the second screen, respectively. This design ensures that the first and second screens do not interfere with the sound pickup of the ring microphone array device located within the rotating axis, enabling it to more accurately and fully acquire the voice information of both parties interacting in front of the first and second screens, thus ensuring greater accuracy in subsequent voice recognition and recording processes.

[0012] In one illustrative embodiment of the dual-screen interactive device, the ring microphone array device is a 6-microphone array device.

[0013] In one illustrative embodiment of the dual-screen interactive device, a plurality of locking portions are provided on the circumferential surface of the rotating shaft; and the dual-screen interactive device further includes a locking member and a reset elastic member. The locking member is movably disposed on the base and can switch between an initial position and an unlocked position. When the locking member is in the initial position, it can lock with a locking portion and prevent the rotation of the rotating shaft. When the locking member is in the unlocked position, it disengages from the locking portion and allows the rotating shaft to rotate. The reset elastic member can provide an elastic force to the locking member to return it to the initial position. This design allows the second screen to lock onto the rotating shaft when it rotates to the desired interactive position, preventing further rotation and ensuring that the second screen remains in the correct interactive position without deflection during interaction. Furthermore, the position of the locking part along the circumference of the rotating shaft can be preset as needed to predetermine the positional relationship between the first and second screens, such as an angle of 90 degrees or 120 degrees. With this angular relationship, it becomes clear which microphone units in the ring microphone array will have a basic corresponding positional relationship with the first screen. By determining whether there is a sound source within a certain distance and at a fixed location of these microphone units, if so, it is identified as the voice of the user on the first screen, thus simplifying and accurately identifying the user's voice information.

[0014] In one illustrative embodiment of the dual-screen interactive device, several locking parts are several locking slots evenly spaced circumferentially along the rotation axis, and the locking member in the initial position can engage in one locking slot. This design allows the locking member in the locking slot to prevent the rotation of the rotation axis.

[0015] In one illustrative embodiment of the dual-screen interactive device, the base of the device has a base, a support wall, and a mounting platform connected sequentially along the height direction. The support wall is connected to the same side of the base and the mounting platform, so that the base and the mounting platform are positioned opposite each other in the height direction. A placement surface is provided on the side of the base facing the mounting platform, and a document scanner is provided on the side of the mounting platform facing the base, corresponding to the placement surface. The first screen is positioned on the other side of the mounting platform relative to the support wall. The rotation axis is located on the side of the mounting platform opposite to the base. This design allows the device to form a workspace for the document scanner, enabling the recording of paper information. The support wall, located on the same side of the mounting platform and the base, provides sufficient operational space for placing or removing documents from both sides of the placement surface, and the rotation of the second screen does not affect it.

[0016] In one illustrative embodiment of the dual-screen interactive device, the device further includes a control circuit board disposed on the back of the second screen. The connecting arm has a heat dissipation cover capable of shielding the control circuit board. The control circuit board is electrically connected to the first screen, the second screen, the document scanner, and the ring microphone array device. This design not only considers the compactness of the overall structure but also addresses the heat dissipation of the control circuit board. The connecting arm not only provides support for the second screen but also accommodates the control circuit board through the heat dissipation cover. This ensures that the control circuit board does not occupy additional space and provides direct and efficient heat dissipation, guaranteeing its stable operation.

[0017] In one illustrative embodiment of the dual-screen interactive device, the device also includes several speakers mounted on the bottom surface of the base, with a control circuit board electrically connected to the speakers. Furthermore, along the horizontal direction, a circular microphone array and the speakers are respectively positioned on either side of the document scanner. This design not only maximizes the separation of the speakers and the circular microphone array in both the vertical and horizontal directions, ensuring that the speakers and the circular microphone array are located at a considerable distance on the same device, thus avoiding mutual interference between them.

In addition, to make the drawings concise and easy to understand, in some drawings, only one of the components with the same structure or function is shown schematically, or only one of them is labeled.

[0034] Figure 1 A schematic diagram illustrating one embodiment of a dual-screen interactive device. Figure 2 yes Figure 1 The diagram shows a three-dimensional view of the dual-screen interactive device from another angle. Figure 1 and Figure 2 As shown, the device includes a base 10, a first screen 20, and a second screen 30. The base 10 has a rotating shaft 32 positioned at its top along the height direction A. The first screen 20 is located on one side of the base. A connecting arm 34 is provided on the back of the second screen 30, and the second screen 30 is connected to the side of the rotating shaft 32 via the connecting arm 34.

[0035] As shown in the figure, the position of the second screen 30 relative to the first screen 20 can be adjusted by rotating the second screen 30. Taking a doctor and patient as an example, the doctor uses the first screen 20 and the patient uses the second screen 30. The patient can rotate the second screen 30, which is connected to the rotation axis 32 via the connecting arm 34, to adjust its relative position to the first screen 20 according to the actual positional relationship with the doctor.

[0036] Inside the rotating shaft 32, there is also a ring-shaped microphone array device 40 that rotates together with the rotating shaft 32. The ring-shaped microphone array device 40 has microphone units. Figure 1 and Figure 2Not shown in the drawing. For the specific structure of the ring microphone array device 40, please refer to [reference needed]. Figure 6 As shown, the ring microphone array device 40 is assembled from a microphone circuit board 41, a sealing ring 43, and a ring mounting bracket 44. The microphone circuit board 41 is equipped with six microphones 42. (See also...) Figure 7 The annular mounting bracket 44 is also provided with receiving slots 45 and sealing sleeves 46 corresponding to each microphone 42. After assembly, each microphone 42 on the microphone circuit board 41, together with its corresponding sealing ring 43, sealing sleeve 46, and receiving slot 45 of the annular mounting bracket 44, constitutes a microphone unit 47. Please also refer to... Figure 8 .Right now Figure 6 The circular microphone array device 40 shown has six microphone units 47. The specific assembly structure of the circular microphone array device 40 will be described in detail later. Furthermore, those skilled in the art will understand that the number of microphone units 47 is not limited to the six shown in the figure, depending on actual needs.

[0037] like Figure 6 As shown, each microphone unit 47 of the circular microphone array device 40 (see Figure 7 The microphones are arranged at even intervals around the axis 329 of the rotating shaft 32, and the top end face 322 of the rotating shaft 32 is provided with a pickup hole 324 corresponding to each microphone unit 47.

[0038] In this ring microphone array device 40, the microphone units 47 are divided into at least two groups, and each group of microphone units 47 needs to be positioned corresponding to the orientation of the second screen 30. Since the pickup holes 324 are configured to correspond to each microphone unit 47, it can be understood that one pickup hole 324 corresponds to one microphone unit 47. Figure 3 , Figure 4 , Figure 5As shown, in the design of 6 microphone units 47, there are 6 corresponding microphone holes 324. Two of these microphone holes 324 are set to the second screen 30, and these two microphone holes 324 form the first microphone hole group 324a. The two microphone units 47 corresponding to the first microphone hole group 324a constitute the microphone group corresponding to the second screen 30. The remaining microphone holes 324 and the corresponding microphone units 47 can form one microphone group or multiple microphone groups. Of course, those skilled in the art will understand that there can be any number of microphone units 47 in a microphone group. Therefore, the number of microphone units 47 set to the second screen 30 is not limited to 2. For example, it can also be 1, 3 or other numbers, as long as there is a microphone group set to the position of the second screen 30. The setting of the microphone hole group is not limited to the number of microphone holes 324 or a specific few microphone holes 324. Only the microphone hole group formed by the microphone holes 324 corresponding to the position of the second screen 30 is called the first microphone hole group 324a. Because the circular microphone array device 40 rotates together with the rotating shaft 32, when the second screen 30 rotates, it will drive the rotating shaft 32 and the circular microphone array device 40 inside it to rotate together. For example, when the second screen 30 rotates from... Figure 3 Turn to Figure 4 or Figure 5 At the angle shown, the first microphone group 324a and the corresponding microphone group rotate together with the second screen 30. It can be seen that no matter what angle the second screen 30 rotates to, the corresponding position of the first microphone group 324a and the corresponding microphone group with the second screen 30 will never change.

[0039] The circular microphone array device 40 can determine the sound source using its individual microphones 42. It is typically used in a static state (immovable state), utilizing the timing of sound information acquired by different microphones 42 to determine the specific angle of the sound source. In the dual-screen interactive device of this application, the second screen 30 is rotated by the user, meaning the user's voice originating from the second screen 30 changes position. If a static circular microphone array device 40 is used, it is necessary not only to determine the direction of the sound source but also to simultaneously determine the orientation of the second screen 30 after rotation in order to infer the user's voice from multiple sound sources. This inference method not only increases the difficulty of the algorithm but also necessitates additional devices to determine the rotation angle of the second screen 30, increasing the overall structural complexity and corresponding production and manufacturing costs.

[0040] At the same time, it is necessary to consider that multiple people may make sounds at different distances in the same location. That is, there may be other people behind the user of the second screen 30, and the sound made by these people will also be captured by the microphone 42 of the ring microphone array device 40. If it is necessary to accurately distinguish whether the speaker is the user, it is also necessary to comprehensively judge which speaker is the user of the second screen 30 based on the speed of sound acquisition.

[0041] Furthermore, it must be considered that when the microphone array is in a static state, the positions of each microphone unit 47 remain unchanged. However, when the speaker is in different locations, the relative position of the speaker to each microphone unit 47 is constantly changing. For example, the speaker may be directly facing one microphone unit 47, or may be located at any angle between two adjacent microphone units 47. In this case, it is difficult to determine the speaker's exact location, requiring algorithmic estimation, and the algorithm's calculation accuracy must be very high. Moreover, considering the above-mentioned situations, if multiple people at different distances are speaking from the same location, it further increases the difficulty of identifying the user on the second screen 30.

[0042] In this application, both the second screen 30 and the ring microphone array device 40 rotate around the same axis 329. The relative positional relationship between the second screen 30 and its corresponding first microphone group 324a (i.e., its corresponding microphone group) remains unchanged. That is, regardless of how the second screen 30 rotates, the location of the sound emitted by the user on the second screen 30 always maintains a relatively constant positional relationship with the corresponding first microphone group 324a and its corresponding microphone group. At this time, the ring microphone array device 40 only needs to determine whether a sound source exists at a specific location corresponding to the first microphone group 324a and its microphone group. Once it is determined that the sound originates from that specific location, it can be determined that it may be the sound emitted by the user of the second screen 30.

[0043] Meanwhile, the relative distance between the second screen 30 and its corresponding first pickup hole group 324a and microphone group remains essentially unchanged, such as Figure 3 to Figure 5 As shown, the second screen 30 will always correspond to the microphone hole in the middle of the first microphone hole group 324a. That is, the relative position of the second screen 30 with each microphone unit 47 will not change, so the location (including direction and distance) of the sound source is fixed for the ring microphone array device 40, which can greatly simplify the algorithm process, improve the response speed, and improve the positioning accuracy.

[0044] The specific usage process of the dual-screen interactive device is as follows: Taking a hospital setting as an example, the dual-screen interactive device provides relevant information to doctors and patients through the first screen 20 and the second screen 30, respectively. Doctors use the first screen 20 to obtain information such as the patient's condition and provide corresponding medical orders and suggestions to the dual-screen interactive device through the first screen 20 or the ring microphone array device 40. Patients use the second screen 30, primarily providing personal information and their physical condition to the dual-screen interactive device through the second screen 30 and the ring microphone array device 40. It can be understood that patients can be guided by the text or image information displayed on the second screen 30, either by inputting data through the second screen 30 or by using voice input through the ring microphone array device 40.

[0045] In actual use, the patient can adjust the relative position of the second screen 30 and the first screen 20 at any time according to their own position. Because the first pickup hole group 324a and the corresponding microphone group in the ring microphone array device 40 always correspond to the patient's position, the patient's voice can be quickly and accurately distinguished from the sound and relevant information can be obtained.

[0046] The dual-screen interactive device does not require much voice information from the doctor, and the recognition requirements are not strict. Therefore, various methods can be used for voice recognition on the doctor's side. For example, voice information that is not identified as the patient's voice within a specific time period (the time during which the doctor interacts with the first screen 20) can be uniformly considered as the doctor's voice information. Alternatively, the usual usage position of the second screen 30 relative to the first screen 20 can be considered. In this usual usage position, the position of the first screen 20 relative to the circular microphone array device 40 is also fixed. An example of this usual usage position is when the second screen 30 and the first screen 20 are at a 180-degree angle to each other (see...). Figure 3 ), or the second screen 30 is perpendicular to the first screen 20 at a 90-degree angle to each other (see Figure 5 In these commonly used positions, the first screen 20 corresponds to some microphone units 47 in the circular microphone array device 40. By determining whether sound is emitted from the location of these microphone units 47 corresponding to the first screen 20 in the commonly used position, the circular microphone array device 40 can quickly distinguish the doctor's voice on one side of the first screen 20 from all sounds. Of course, for the sound discrimination on the first screen 20 side with less voice information, it can also be estimated directly through algorithms.

[0047] In one illustrative embodiment of the dual-screen interactive device, the ring microphone array device 40 is specifically assembled into the rotating shaft 32 as follows: Figure 6 As shown, the rotating shaft 32 includes a rotating shaft body 325 and an end cap 326, wherein the rotating shaft body 325 is rotatably disposed on the top of the base 10 (see Figure 10). Figure 1 andFigure 2 The top of the rotating shaft body 325 has an installation space 321, and in the actual product, the rotating shaft body 325 can be a cylinder with a frustum formed on the top of the cylinder. The interior of the frustum is the installation space 321. The end cap 326 can be assembled to the rotating shaft body 325 to close the installation space 321. The outer surface of the end cap 326 forms a top end face 322 with a pickup hole 324.

[0048] The specific assembly structure of the aforementioned ring microphone array device 40 is as follows: Figure 6 , Figure 7 As shown, the ring microphone array device includes a microphone circuit board 41, several sealing rings 43 disposed between the microphone circuit board 41 and the end cap 326, and a ring mounting bracket 44. The microphone circuit board 41 integrates several microphones 42, each corresponding to a pickup hole 324 of the end cap 326. See [link to documentation]. Figure 7 , Figure 7 As shown Figure 6 View B of microphone circuit board 41. Microphone 42 is integrated into microphone circuit board 41. Each sealing ring 43 is located between the corresponding microphone 42 and the pickup hole 324. The positions of each sealing ring 43 and each microphone 42 correspond to each other.

[0049] like Figure 6 As shown, the annular mounting bracket 44 has receiving slots 45 corresponding to each microphone 42, and a sealing sleeve 46 is provided in the receiving slot 45. When the microphone circuit board 41 is combined with the annular mounting bracket 44, as shown... Figure 8 As shown, the microphone 42 of the microphone circuit board 41 is placed precisely within the receiving groove 45 with the sealing sleeve 46. The annular mounting bracket 44 can clamp and assemble the microphone circuit board 41 to the end cap 326. The corresponding receiving grooves 45, sealing sleeves 46, microphones 42, and sealing rings 43 constitute the aforementioned microphone unit 47. This arrangement of the annular microphone array device 40 within the mounting space 321 of the rotating shaft body 325 allows the annular microphone array device 40 to rotate with the rotating shaft 32. The sealing rings 43 and sealing sleeves 46 in the microphone unit 47 ensure that the microphone 42 is in a sealed space, shielding it from ambient noise and enabling it to more accurately receive and record the operator's voice information.

[0050] In one illustrative embodiment of the rotating shaft 32, such as Figure 6As shown, the rotating shaft 32 also includes two arc-shaped lights 327. The assembled end cap 326 can hold the arc-shaped lights 327 between the rotating shaft body 325 and the end cap 326, and make each arc-shaped light 327 correspond to a set of microphones. In the design of the circular microphone array device 40 with six microphone units 47 described above, it is known that one group of microphones is always set to the second screen 30. The second screen 30 corresponds to one arc-shaped light 327, and the other arc-shaped light 327 corresponds to the other group of microphones. Those skilled in the art will understand that the two arc-shaped lights 327 correspond to the speakers of the first screen 20 and the second screen 30, respectively. When the dual-screen interactive device determines that the speaker of the second screen 30 is speaking, its corresponding arc-shaped light 327 will light up. If it determines that the speaker of the first screen 20 is speaking, the arc-shaped light 327 corresponding to the first screen 20 will light up. If the speakers of the first screen 20 and the second screen 30 are speaking simultaneously, the arc-shaped lights 327 corresponding to the first screen 20 and the second screen 30 will light up simultaneously. This design of the arc-shaped light 327 can be used to indicate to the speaker that their spoken information is being received by the device, thus ensuring that both parties can promptly confirm whether their spoken information is being received and recorded during the output of voice information.

[0051] In the actual product, the height of the top end face 322 of the rotating shaft 32 is higher than the height of the first screen 20 and the second screen 30, respectively. This ensures that the ring microphone array device 40 is not interfered with by the first screen 20 and the second screen 30 when receiving voice information, thus ensuring that the device is more accurate in the subsequent voice recognition and recording process.

[0052] To ensure the second screen 30 remains stable after being rotated to the appropriate interactive position, then as follows: Figure 9 As shown, you can refer to the following: Figure 2 As shown, a portion of the rotating shaft 32 is disposed inside the base 10. Several locking parts 35 are provided on the circumferential surface of the rotating shaft 32 inside the base 10. The dual-screen interactive device is also provided with a locking member 36. The locking member 36 is movably disposed on the base 10. Specifically, the locking member 36 can move up and down along the height direction A and switch between an initial position and an unlocked position. When the locking member 36 is in the initial position, it can lock with a locking part 35 and prevent the rotation of the rotating shaft 32. When the locking member 36 is in the unlocked state, it is released from the locking part 35 and allows the rotating shaft 32 to rotate. The base 10 is also provided with a reset elastic member 37. In the actual product, the reset elastic member 37 is a spring structure. One end of it is disposed at the bottom of the locking member 36 and the other end is connected to the base 10. It can provide an elastic force to the locking member 36 to return it to the initial position.

[0053] The locking part 35 can be preset in the circumferential direction of the rotating shaft 32 as needed. After the locking part 36 is locked with a locking part 35, the specific positional relationship between the first screen 20 and the second screen 30 can be determined. For example, the angle between the two will be at several fixed positions such as 90 degrees, 105 degrees, 120 degrees, 135 degrees, 150 degrees, 165 degrees, and 180 degrees. It can be determined which microphone units 47 will have a basic corresponding positional relationship with the first screen 20 at these angle positions. At this time, it is only necessary to determine whether there is a sound source within a certain distance range relative to the fixed position of these microphone units 47. If there is a sound source, it is determined that the sound is the voice of the user of the first screen 20. This simplifies and accurately identifies the voice information of the user of the first screen 20.

[0054] like Figure 9 As shown, in one illustrative embodiment, the locking parts 35 can be a plurality of locking grooves evenly spaced along the circumference of the rotation axis 32. One end of the locking member 36 is a structure that can lock into the locking groove, and the other end is provided with a pressing part 361. The reset elastic member 37 is provided at the bottom of the pressing part 361. When the pressing part 361 is pressed away from the initial position, the locking member 36 disengages from the current locking groove and is in the unlocked state, then the rotation axis 32 can rotate, and the second screen 30 can rotate. When the second screen 30 rotates to the appropriate interactive position, the pressing part 361 is released, and the spring provides elastic force to the locking member 36, causing the locking member 36 to return to the initial position. The locking member 36 will then be locked into another locking groove again, and the rotation axis 32 will remain stable and not rotate. This design allows the second screen 30 to rotate or be fixed as needed. The fixed second screen 30 will not deflect during the interaction, thus ensuring the stability of the second screen 30 during the interaction. At the same time, no matter where the rotating axis 32 is locked, the second screen 30 can always be aligned with the first pickup hole group 324a and its microphone group.

[0055] exist Figure 1 and Figure 2 In one embodiment of the dual-screen interactive device shown, the base 10 of the dual-screen interactive device has a base 12, a support wall 14, and a mounting platform 16 connected sequentially along the height direction A. The support wall 14 is connected to the same side of the base 12 and the mounting platform 16, so that the base 12 and the mounting platform 16 are arranged opposite each other in the height direction A. A placement surface 122 is provided on the side of the base 12 facing the mounting platform 16, and a high-speed scanner 162 corresponding to the placement surface 122 is provided on the side of the mounting platform 16 facing the base 12. The first screen 20 is located on the other side of the mounting platform 16 opposite to the support wall 14. The rotation shaft 32 is located on the side of the mounting platform 16 opposite to the base 12.

[0056] The aforementioned dual-screen interactive device sets the base 10 as a structure consisting of a base 12, a support wall 14, and a mounting platform 16. The space between the mounting platform 16 and the base 12 forms the working space of the document scanner 162. The support wall 14 is located on the same side of the mounting platform 16 and the base 12, providing operational space for placing or removing documents from the placement surface 122 from both sides. Even if the second screen 30 rotates 90 degrees relative to the first screen 20 on the mounting platform 16, as... Figure 5 As shown, one side will still be left open for easy insertion or removal of photographed documents.

[0057] exist Figure 10 In one embodiment of the dual-screen interactive device shown, the dual-screen interactive device further includes a control circuit board 38, which is disposed on the back of the second screen 30, and the connecting arm 34 has a heat dissipation shielding portion 341 capable of covering the control circuit board 38. Figure 11 The dashed arrows schematically illustrate the wiring connections between the control circuit board 38 and other components. Specifically, the control circuit board 38 can electrically connect to the first screen 20, the second screen 30, the document scanner 162, and the ring microphone array device 40 within the rotating shaft 32. Except for the second screen 30, the wiring connections between the control circuit board 38 and other components are achieved through wiring within the connecting arm 34 and the rotating shaft 32.

[0058] The aforementioned design of the control circuit board 38 not only considers the compactness of the overall structural space but also takes into account the heat dissipation of the control circuit board 38. The connecting arm 34 not only provides support for the second screen 30 but also accommodates the control circuit board 38 through the heat dissipation cover 341. This ensures that the control circuit board 38 does not occupy additional overall space and provides the most direct and efficient heat dissipation effect, guaranteeing its stable operation. Those skilled in the art will understand that the connecting arm 34 is typically made of a metal material with good heat dissipation and rigidity.

[0059] exist Figure 11 In one embodiment of the dual-screen interactive device shown, the dual-screen interactive device further includes several speakers 60, which can be seen simultaneously. Figure 12 In the embodiment shown in the figure, the device includes two speakers 60, which are disposed on the bottom surface of the base 12 and along... Figure 1In the horizontal direction, the circular microphone array device 40 and the speaker 60 are respectively positioned on both sides of the document scanner 162. This structural design, based on the overall structure, not only maximizes the separation of the speaker 60 and the circular microphone array device 40 in the vertical direction but also in the horizontal direction, ensuring that the speaker 60 on the base 12 and the circular microphone array on the mounting platform 16 are located at a considerable distance on the same device, avoiding mutual interference. Simultaneously, the speaker 60 is also electrically connected to the control circuit board 38, allowing the control circuit board 38 to provide voice prompts to the user during use.
