Description

Technical Field

[0001] This application relates to the technical field of electronic device accessories, and particularly to an active pen with a voice pickup function and an electronic device. Background Art

[0002] In the related art, for electronic devices such as tablet computers and laptop computers, their microphones are usually built-in and the voice pickup channels are directly connected. The opening / closing of the microphone is simply achieved by software, and the risk of user privacy leakage is relatively high. In addition, in an online meeting scenario, the voice pickup range of the microphone is limited. The farther away from the electronic device the participants are, the worse the voice pickup effect of the microphone on them. This results in the need to frequently move the electronic device during the meeting to achieve clear voice pickup for each participant, which not only reduces the meeting efficiency but also affects the operation of the meeting host on the electronic device. Summary of the Invention

The state switching device includes a first component and a second component. One end of the button is slidably inserted into the end of the active pen body opposite to the pen tip, and the other end is exposed outside. The microphone is embedded in the button and located inside the active pen body. A first voice pickup hole adjacent to the microphone is formed on the outer side wall of the active pen body. The first component is located inside the active pen body and disposed on one end of the button, and the second component is disposed on the inner side wall of the active pen body. The active pen has a normal state and a voice pickup state. In the normal state, the microphone is misaligned with the first voice pickup hole, and in the voice pickup state, the microphone is aligned with the first voice pickup hole. The first component and the second component cooperate to: lock the button when the button slides into the active pen body, or unlock the button to make the button bounce back outside the active pen body to switch between the normal state and the voice pickup state.

Metal contacts are provided on the outer sides of the two first metal shrapnel. Through holes for exposing the metal contacts to the outside are formed on opposite sides of the pen cap. The two first metal shrapnel are respectively used to electrically connect to the positive and negative electrodes of an external power supply through their respective metal contacts.

[0009] Further, the active pen further includes a power management module disposed within the pen shaft.

[0012] In some implementation solutions, the active pen further includes a plurality of magnets, and the plurality of magnets are all attached to the inner side wall of the pen shaft, and the plurality of magnets are distributed at different positions.

[0013] The second aspect of the present application provides an electronic device, including an electronic device body and the active pen provided in the first aspect of the present application that is built in or adsorbed on the electronic device body.

[0014] For the active pen provided in the first aspect of the present application, it includes a button, a microphone, an active pen body, a first component, and a second component that cooperates with the first component. One end of the button is slidably inserted into the end of the active pen body opposite to the pen tip, and the other end is exposed outside.

The first component is located inside the active pen body and is provided at one end of the button, and the second component is provided on the inner side wall of the active pen body. In practical applications, the cooperation between the first component and the second component is used for: locking the button when the button slides into the active pen body, or unlocking the button to make the button bounce back outside the active pen body, so as to switch between the sound pickup state (the microphone is aligned with the first sound pickup hole) and the normal state (the microphone is misaligned with the first sound pickup hole). It can be seen that through the sliding of the button into / out of the active pen body and the cooperation between the first component and the second component, the active pen of the present application can be freely switched between the normal state and the sound pickup state. Compared with the direct-through sound pickup channel in the traditional solution, in the normal state where sound pickup is not required, the microphone of the active pen of the present application will be blocked by the wall surface of the active pen body due to being misaligned with the first sound pickup hole, thereby improving privacy and effectively reducing the risk of user privacy leakage; in addition, in the online meeting scenario, compared with the traditional solution of frequently moving the electronic device in order to achieve clear sound pickup for each participant, the microphone is built into the active pen in the present application. In this way, in the online meeting scenario, only the active pen needs to be moved, without moving the electronic device. At the same time, since the active pen is very light, it is very convenient to move, which not only improves the meeting efficiency but also does not affect the operation of the meeting host on the electronic device, and finally effectively improves the sound pickup range of the microphone in the online meeting scenario.

[0015] For the electronic device provided in the second aspect of the present application, since it includes the active pen with the sound pickup function provided in the first aspect of the present application, it has all the advantages of this active pen. Brief Description of the Drawings

Detailed implementation manners

[0037] In the related art, for electronic devices such as tablet computers and laptop computers, their microphones are usually built-in and the sound pickup channels are directly connected. The microphone switch is simply realized by software, and the risk of user privacy leakage is relatively high. In addition, in an online meeting scenario, the sound pickup range of the microphone is limited. The farther an attendee is from the electronic device, the worse the sound pickup effect of the microphone on them. This leads to the need to frequently move the electronic device during the meeting to achieve clear sound pickup of each attendee. However, the electronic device is relatively heavy and is very inconvenient to move, which not only reduces the meeting efficiency but also affects the operation of the meeting host on the electronic device. In view of this, the present application proposes a stylus with a sound pickup function and an electronic device in the following embodiments to solve the above-mentioned drawbacks existing in the related art.

[0038] In order to make the objectives, technical solutions, and advantages of the present application more obvious and understandable, the present application will be clearly and completely described below in conjunction with the embodiments of the present application and the corresponding drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. It should be understood that the various embodiments of the present application described below are only used to explain the present application and are not used to limit the present application. That is, based on the various embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0039] Please refer to Figures 1 to 5, Figure 1 is a schematic structural diagram of an active pen, Figure 2 is an exploded schematic diagram of the active pen, Figure 3 is Figure 2 a partial enlarged view of part A in Figure 4 is a sectional view of the active pen, Figure 5 is Figure 4 a partial enlarged view of part B in. This embodiment provides an active pen with a sound pickup function. The active pen includes a button 2, a microphone 3, an active pen body 1, and a state switching device (not shown in the figure). The state switching device includes a cooperating first component 4 and a second component 5. One end of the button 2 is slidably inserted (i.e., slidably inserted) into the end of the active pen body 1 opposite to the pen tip 11, and the other end is exposed. The microphone 3 is embedded in the button 2 and located inside the active pen body 1. A first sound pickup hole 131 adjacent to the microphone 3 is formed on the outer side wall of the active pen body 1. The first component 4 is located inside the active pen body 1 and is provided at one end of the button 2. The second component 5 is provided on the inner side wall of the active pen body 1. Among them, the microphone 3 is not limited to one, and can also be two or more, and can be specifically selected according to actual needs. This embodiment does not make a unique limitation on this; preferably, the microphone 3 includes two, and the two microphones 3 are respectively embedded on opposite sides of the button 2. Then the first sound pickup holes 131 also include two, and the two first sound pickup holes 131 are respectively formed on opposite outer side walls of the active pen body 1 and are respectively adjacent to the two microphones 3.

[0040] In this embodiment, the active pen has two working states, which are respectively a normal state without sound pickup (as shown in Figure 18 ) and a sound pickup state that requires sound pickup (as shown in Figure 17As shown in the figure, in the normal state, the microphone 3 is misaligned with the first sound pickup hole 131, so that the microphone 3 is shielded. In the sound pickup state, the microphone 3 is aligned with the first sound pickup hole 131, and the microphone 3 can pick up sound through the first sound pickup hole 131. Specifically, the conversion between the normal state and the sound pickup state mainly depends on the sliding of the button 2 into / out of the active pen body 1 and the cooperation between the first component 4 and the second component 5. In this embodiment, the cooperating first component 4 and second component 5 are used to: lock the button 2 when the button 2 slides into the active pen body 1, or unlock the button 2 to make the button 2 bounce out of the active pen body 1, so that the microphone 3 and the first sound pickup hole 131 are switched between misalignment and alignment, and further the active pen is switched between the normal state and the sound pickup state. It can be understood that in actual applications, there are two forms. The first form is that "after the button 2 slides into the active pen body 1 in place and is locked, the active pen is in the normal state; after unlocking the button 2 and making it bounce out of the active pen body 1 in place, the active pen is in the sound pickup state", and the second form is that "after the button 2 slides into the active pen body 1 in place and is locked, the active pen is in the sound pickup state; after unlocking the button 2 and making it bounce out of the active pen body 1 in place, the active pen is in the normal state". The active pen of this embodiment is applicable to both of the above two forms. As for which form to specifically adopt, it can be determined according to actual needs. This embodiment does not make a unique limitation on this, but in the following embodiments, the first form will be taken as an example for relevant description.

[0041] As can be seen from the above, in this embodiment, by sliding the button 2 into / out of the active pen body 1 and the cooperation between the first component 4 and the second component 5, the active pen can be freely switched between the normal state and the sound pickup state. Compared with the direct-through sound pickup channel in the traditional solution, in the normal state where sound pickup is not required, the microphone 3 of the active pen in this embodiment will be blocked by the wall surface of the active pen body 1 due to being misaligned with the first sound pickup hole 131, thereby improving privacy and reducing the risk of user privacy leakage. In addition, in the online meeting scenario, compared with the traditional solution of frequently moving heavy electronic devices in order to achieve clear sound pickup for each participant, in this embodiment, the microphone 3 is built into the active pen. In this way, in the online meeting scenario, only the active pen needs to be moved, and there is no need to move the electronic device. At the same time, since the active pen is very light, it is very convenient to move, which not only improves the meeting efficiency but also does not affect the operation of the meeting host on the electronic device, and finally effectively improves the sound pickup range of the microphone 3 in the online meeting scenario.

[0042] In some embodiments, please combine Figures 6 to 10 , Figure 6 which is another exploded view of the active pen, Figure 7 which is another exploded view of the active pen, Figure 8 is Figure 7 the partial enlarged view at the F position inFigure 9 is Figure 7 a partial enlarged view of the G position in Figure 10 is Figure 6 a partial enlarged view of the C position in. In addition to the pen tip 11 mentioned above, the active pen body 1 further includes a pen barrel 12, a pen cap 13 and a sleeve 14. One end of the pen barrel 12 is connected to the pen tip 11, and the other end is connected to one end of the pen cap 13. One end of the sleeve 14 is inserted into the pen cap 13 and the pen barrel 12 in sequence from the other end of the pen cap 13, and the other end is located inside the pen cap 13. The first sound pickup hole 131 is opened on the pen cap 13. Based on this, one end of the button 2 is slidably inserted into the sleeve 14, and the other end is exposed outside. The microphone 3 is embedded on the button 2 and is located inside the sleeve 14. A second sound pickup hole 141 aligned with the first sound pickup hole 131 is opened on the outer side wall of the sleeve 14. The first component 4 is located inside the sleeve 14 and is arranged on one end of the button 2. The second component 5 is arranged on the inner side wall of the sleeve 14.

[0043] It can be understood that the pen cap 13 and the sleeve 14 are relatively fixed, that is, the first sound pickup hole 131 and the second sound pickup hole 141 are always aligned. When the active pen is in the sound pickup state, the microphone 3, the first sound pickup hole 131 and the second sound pickup hole 141 are aligned with each other. When the active pen is in the normal state, although the first sound pickup hole 131 and the second sound pickup hole 141 are aligned, the microphone 3 is misaligned with the two, so that the microphone 3 is shielded inside the sleeve 14. In addition, it should be noted that the active pen of the present application is actually an accessory of an electronic device (such as a tablet computer, a notebook computer, etc.). When the active pen is not needed, the active pen can be first placed in the normal state, and then the active pen can be placed inside the electronic device body. When the sound pickup function of the active pen is needed, the active pen can be first placed in the sound pickup state, and then the active pen can be adsorbed (such as magnetically) on the electronic device body; Based on this, the active pen further includes a plurality of magnets 9, and the plurality of magnets 9 are all attached to the inner side wall of the pen barrel 12, and the plurality of magnets 9 are distributed at different positions on the inner side wall of the pen barrel 12. Through these magnets 9, the active pen can be adsorbed on the electronic device body.

[0044] In some embodiments, when the active pen is in the voice pickup state, the user can press the button 2 into the active pen body 1. The microphone 3 will move into the active pen body 1 together with the button 2. When the button 2 moves into the active pen body 1 to a certain position, the first component 4 will cooperate with the second component 5 to lock the button 2 in this position, making the microphone 3 misaligned with the first voice pickup hole 131, and the active pen enters the normal state from the voice pickup state. When the active pen is in the normal state, the user can still press the button 2 into the active pen body 1. The first component 4 will cooperate with the second component 5 to release the lock on the button 2. Then the user stops pressing the button 2, and the button 2 will rebound out of the active pen body 1 due to the lack of pressing force until the microphone 3 is aligned with the first voice pickup hole 131, and the active pen returns to the voice pickup state from the normal state.

[0045] As one of the embodiments, please refer to Figures 11 to 16 , Figure 11 which shows an exploded view of the first component, Figure 12 and Figure 11 shows a partial enlarged view of the D position in Figure 13 which shows a wireframe view of the second component, Figure 14 and Figure 13 shows a partial enlarged view of the E position in Figure 15 which shows a cross-sectional view of the second component, Figure 16 and

[0046] Specifically, four pressing blocks (not shown in the figure) are formed on the outer sidewall of the pressing ring 44 and are equidistantly distributed around the central axis of the pressing ring 44. The four pressing blocks include two opposite first pressing blocks 441 and two opposite second pressing blocks 442. The two first pressing blocks 441 and the two second pressing blocks 442 are respectively symmetrical about the central axis of the pressing ring 44. At one end of the first pressing block 441 adjacent to the ejector rod 43, a first upper guiding inclined surface 4411 is formed and extends obliquely towards the ejector rod 43. At one end of the second pressing block 442 adjacent to the ejector rod 43, a second upper guiding inclined surface 4421 is formed and extends obliquely towards the ejector rod 43. On the outer sidewall of the ejector rod 43, two ejector posts 431 are formed and are symmetrical about the central axis of the ejector rod 43. At one end of the ejector post 431 adjacent to the pressing ring 44, a lower guiding inclined surface 4311 is formed and extends obliquely towards the pressing ring 44. In practical applications, the two lower guiding inclined surfaces 4311 are respectively in line contact with the two first upper guiding inclined surfaces 4411 or the two second upper guiding inclined surfaces 4421. As for when the lower guiding inclined surface 4311 is in line contact with the first upper guiding inclined surface 4411 and when it is in line contact with the second upper guiding inclined surface 4421, this mainly depends on the working state of the active pen (i.e., the normal state and the sound pickup state).

[0047] Further, the second assembly 5 includes a fixing block 51 and two arc-shaped clamping plates 52. The outer sidewall of the fixing block 51 is attached to the inner sidewall of the sleeve 14. A guiding hole 511 is formed in the fixing block 51 for the rotating rod 42 and the sleeve rod 41 to pass through. The pressing ring 44, the ejector rod 43, and the two arc-shaped clamping plates 52 are all located on the side of the fixing block 51 away from the button 2. The two arc-shaped clamping plates 52 are symmetrically attached to the inner sidewall of the sleeve 14 about the central axis of the fixing block 51. One end of each of the two arc-shaped clamping plates 52 is provided on the fixing block 51. The two arc-shaped clamping plates 52 are spaced apart from each other, so that two sliding channels 53 are formed between the two arc-shaped clamping plates 52 and are symmetrical about the central axis of the fixing block 51. At one end of each arc-shaped clamping plate 52 away from the button 2, there is a sliding-out transition surface 521 that extends obliquely from one side towards the elastic member 45, a straight surface 522 that extends from the sliding-out transition surface 521 towards the button 2, and a sliding-in transition surface 523 that extends obliquely from the straight surface 522 towards the elastic member 45. A clamping groove 524 is formed between the straight surface 522 and the sliding-in transition surface 523 in each arc-shaped clamping plate 52. And the sliding-out transition surface 521 of one arc-shaped clamping plate 52 is connected to the sliding-in transition surface 523 of the other arc-shaped clamping plate 52 in the same sliding channel 53.

[0048] On this basis, the two first pressing blocks 441 are respectively slidably disposed in the two sliding channels 53. The ejector rod 43 and the two second pressing blocks 442 are both located between the two arc-shaped clamping plates 52, and the two second pressing blocks 442 respectively correspond to the two clamping grooves 524. In addition, when the active pen is in the sound pickup state, the pressing ring 44 is in contact with the side of the fixed block 51 away from the button 2, and the two ejector posts 431 are respectively slidably disposed in the two sliding channels 53. The two lower guiding inclined surfaces 4311 of the two ejector posts 431 are in line contact with the two first upper guiding inclined surfaces 4411 of the two first pressing blocks 441 respectively; when the active pen is in the normal state, the ends of the two ejector posts 431 adjacent to the button 2 are respectively clamped into the two clamping grooves 524, and one sides of the two lower guiding inclined surfaces 4311 of the two ejector posts 431 are in line contact with the two sliding transition surfaces 523 respectively, and the other sides are in line contact with the two second upper guiding inclined surfaces 4421 of the two second pressing blocks 442 respectively.

[0049] That is to say, in practical applications, as Figure 17 shown, when the active pen is in the sound pickup state, the user can press the button 2 into the sleeve 14, and the sleeve rod 41, the rotating rod 42, the pressing ring 44 and the ejector rod 43 will all move into the sleeve 14. That is, the two first pressing blocks 441 will respectively push the two ejector posts 431 to slide in the two sliding channels 53 towards the pen tip 11. When the two ejector rods 43 respectively disengage from the two sliding channels 53, the two lower guiding inclined surfaces 4311 of the two ejector posts 431 will respectively slide towards the two clamping grooves 524 relative to the two first upper guiding inclined surfaces 4411 of the two first pressing blocks 441. When the two lower guiding inclined surfaces 4311 respectively disengage from the two first upper guiding inclined surfaces 4411, the two ejector posts 431 will respectively enter the two clamping grooves 524 and the two lower guiding inclined surfaces 4311 will respectively be in line contact with the two sliding transition surfaces 523 of the two clamping grooves 524. After the user stops pressing the button 2, under the elastic force of the return spring, the two lower guiding inclined surfaces 4311 of the two ejector posts 431 will respectively slide along the two sliding transition surfaces 523 of the two clamping grooves 524 towards the two straight surfaces 522 until the two ejector posts 431 respectively abut against the two straight surfaces 522. At this time, the ends of the two ejector posts 431 adjacent to the button 2 are respectively clamped into the two clamping grooves 524, the microphone 3 is misaligned with the two sound pickup holes (i.e., the first sound pickup hole 131 and the second sound pickup hole 141), and the active pen enters the normal state as shown in Figure 17 shown from the sound pickup state as shown in Figure 18 shown.

[0050] When the active pen is in the normal state, the user can press the button 2 into the sleeve 14, and the sleeve rod 41, the rotating rod 42, the pressing ring 44 and the ejector rod 43 will all move into the sleeve 14. That is, the two second pressing blocks 442 will respectively push the two ejector posts 431 to slide in the two card slots 524 towards the pen tip 11. When the two ejector rods 43 respectively disengage from the two card slots 524, the two lower guiding inclined surfaces 4311 of the two ejector posts 431 will respectively slide towards the two sliding channels 53 relative to the two second upper guiding inclined surfaces 4421 of the two second pressing blocks 442. When the two lower guiding inclined surfaces 4311 respectively disengage from the two second upper guiding inclined surfaces 4421, the two lower guiding inclined surfaces 4311 of the two ejector posts 431 will respectively be in line contact with the two sliding-out transition surfaces 521 of the two card slots 524. After the user stops pressing the button 2, under the elastic force of the return spring, the two lower guiding inclined surfaces 4311 of the two ejector posts 431 will respectively slide along the two sliding-out transition surfaces 521 of the two card slots 524 towards the two sliding channels 53 until the two ejector posts 431 respectively slide into the two sliding channels 53. At this time, the two ejector posts 431 will no longer be blocked by the two arc-shaped clamping plates 52, and the sleeve rod 41, the rotating rod 42, the pressing ring 44 and the ejector rod 43 will all move out of the sleeve 14. Finally, the pressing ring 44 will be attached to the side of the fixed block 51 away from the button 2. In the two sliding channels 53, the two lower guiding inclined surfaces 4311 of the two ejector posts 431 will respectively be in line contact with the two first upper guiding inclined surfaces 4411 of the two first pressing blocks 441, and the microphone 3 will be aligned with the two sound pickup holes, and the active pen enters the Figure 17 pickup state as shown.

[0051] Of course, the structures of the first component 4 and the second component 5 are not limited to those described above. In other embodiments, the first component 4 and the second component 5 can also adopt other structures commonly used in the art with locking / unlocking functions. For example: both the first component 4 and the second component 5 are permanent magnets. The user can press the button 2 into the sleeve 14 until the two permanent magnets are magnetically attracted together and the button 2 is locked. If the user wants to unlock the button 2, then the user only needs to pull the button 2 out of the sleeve 14 to separate the two permanent magnets; or, the first component 4 is a permanent magnet and the second component 5 is an electromagnet. After the electromagnet is energized, it adsorbs the permanent magnet, causing the button 2 to slide into the sleeve 14 until the permanent magnet is magnetically attracted to the electromagnet and the button 2 is locked. If the user wants to unlock the button 2, then only the electromagnet needs to be powered off. After the power is off, the magnetic force between the electromagnet and the permanent magnet disappears, and the button 2 will slide out of the sleeve 14 under the elastic force of the elastic member 45. It should be noted that the structures of the first component 4 and the second component 5 in this application can be designed according to actual needs, and this application does not make a unique limitation on this.

[0052] In some embodiments, please refer to Figures 1 to 9, in addition to the structure given above, the active pen further includes a battery 6. The battery 6 is disposed within the pen barrel 12 and electrically connected to the microphone 3 to provide the electrical energy required for the operation of the microphone 3. As an embodiment, the active pen further includes two first metal elastic pieces 7 and two second metal elastic pieces 8. Both of the two first metal elastic pieces 7 are disposed within the pen cap 13 and are respectively located on opposite sides of the sleeve 14. The two first metal elastic pieces 7 are respectively electrically connected to the positive and negative electrodes of the battery 6. The sleeve 14 is provided with two axially extending and opposite sliding holes (not shown in the figure). The two sliding holes respectively correspond to the two first metal elastic pieces 7. Both of the two second metal elastic pieces 8 are disposed within the sleeve 14. One ends of the two second metal elastic pieces 8 are respectively embedded on opposite sides of the button 2 and are respectively electrically connected to the positive and negative electrodes of the microphone 3, and the other ends respectively pass through the two sliding holes and are in electrical contact with the inner sides of the two first metal elastic pieces 7. Thus, the electrical connection between the battery 6 and the microphone 3 can be achieved. It can be understood that when the button 2 slides up and down within the sleeve 14, the two second metal elastic pieces 8 will also slide up and down within the two sliding holes respectively along with the button 2. That is, the purpose of providing the two sliding holes on the sleeve 14 is not only to enable the two second metal elastic pieces 8 to be in electrical contact with the two first metal elastic pieces 7 outside the sleeve 14, but also to provide space for the up and down sliding of the two second metal elastic pieces 8. At the same time, since the relationship between the second metal elastic piece 8 and the first metal elastic piece 7 is electrical contact, when the button 2 slides within the sleeve 14, the second metal elastic piece 8 will also slide on the first metal elastic piece 7 and will not separate from the first metal elastic piece 7, thereby always ensuring the electrical contact between the second metal elastic piece 8 and the first metal elastic piece 7 and avoiding damaging the electrical connection between the microphone 3 and the battery 6.

[0053] Furthermore, metal contacts 10 are respectively disposed on the outer sides of the two first metal elastic pieces 7. Through holes 132 for exposing the metal contacts 10 to the outside are respectively opened on opposite sides of the pen cap 13. The two first metal elastic pieces 7 are respectively used to be electrically connected to the positive and negative electrodes of an external power source through their respective metal contacts 10 so as to charge the battery 6 through the external power source. It can be understood that not only one metal contact 10 is limited to be disposed on a single first metal elastic piece 7, but also two or more metal contacts 10 can be disposed. Specifically, it can be selected according to actual requirements. This embodiment does not make a unique limitation in this regard, and the accompanying drawings are only taken as an example, which shows the situation where two metal contacts 10 are disposed on a single first metal elastic piece 7.

[0054] In addition, it should be noted that the implementation manner of the electrical contact between the second metal elastic piece 8 and the first metal elastic piece 7 is not limited to providing two opposite sliding holes on the sleeve 14. In other embodiments, two axially extending and opposite mounting holes (not shown in the figure) can also be opened on the sleeve 14, and the two first metal elastic pieces 7 are respectively disposed in the two mounting holes. In this way, the two second metal elastic pieces 8 within the sleeve 14 can be in electrical contact with the two first metal elastic pieces 7 respectively without having to pass through the sleeve 14.

[0055] As one of the embodiments, the active pen of the present application further includes a power management module (not shown in the figure) disposed in the pen shaft 12. The two first metal elastic sheets 7 are respectively electrically connected to the positive and negative electrodes of the battery 6 through the power management module. When charging the battery 6 using an external power source, the power management module can manage the charging of the battery 6. Further, the active pen further includes a wireless communication module (not shown in the figure) disposed in the button 2. The wireless communication module is used for communication connection with external electronic devices such as tablet computers and laptop computers. The power management module is communicatively connected to the wireless communication module. The power management module can detect the status information (such as voltage, current, heat, and power) of the battery 6 in real time and transmit the detected status information to the wireless communication module. The wireless communication module can send the status information of the battery 6 to the electronic device for display, so that the user can understand the status of the battery 6 in real time.

[0056] As one of the embodiments, the active pen further includes a switch module (not shown in the figure) and a position detection module (not shown in the figure). The switch module is disposed in the button 2, and the position detection module is disposed in the sleeve 14. The microphone 3 is communicatively connected to the switch module. The switch module and the position detection module are respectively communicatively connected to the wireless communication module. In actual applications, the position detection module can detect the position information of the button 2 in the sleeve 14 in real time and transmit it to the wireless communication module. The wireless communication module can send the position information to the electronic device, so that the electronic device can judge the working state of the active pen according to the position information and issue a switch command to the wireless communication module according to the judged working state. The wireless communication module can also transmit the switch command to the switch module, and the switch module can control the switch of the microphone 3 according to the switch command. Specifically, if the electronic device judges that the active pen is in the voice pickup state according to the position information, the switch command issued by it will instruct to turn on the microphone 3, that is, the switch module will control the microphone 3 to turn on for voice pickup; if the electronic device judges that the active pen is in the normal state according to the position information, the switch command issued by it will instruct to turn off the microphone 3, that is, the switch module will control the microphone 3 to turn off.

[0057] The above embodiments are only the preferred implementations of the present application, and they are not the only limitations on the active pen with a sound pickup function and related electronic devices; in this regard, those skilled in the art can flexibly set according to the actual application scenario on the basis of the above embodiments. It can be understood that through the implementation of the above embodiments of the present application, the active pen is jointly composed of the button 2, the microphone 3, the active pen body 1, the first component 4 and the second component 5 that cooperates with the first component 4. One end of the button 2 is slidably inserted into the end of the active pen body 1 opposite to the pen tip 11, and the other end is exposed outside. The microphone 3 is embedded in the button 2 and is located inside the active pen body 1. A first sound pickup hole 131 adjacent to the microphone 3 is formed on the outer side wall of the active pen body 1. The first component 4 is located inside the active pen body 1 and is provided at one end of the button 2. The second component 5 is provided on the inner side wall of the active pen body 1. In practical applications, the cooperation between the first component 4 and the second component 5 is used for: locking the button 2 when the button 2 slides into the active pen body 1, or unlocking the button 2 to make the button 2 bounce back outside the active pen body 1, so as to switch between the sound pickup state (the microphone 3 is aligned with the first sound pickup hole 131) and the normal state (the microphone 3 is misaligned with the first sound pickup hole 131). Thus, it can be seen that through the sliding of the button 2 into / out of the active pen body 1 and the cooperation between the first component 4 and the second component 5, the active pen can be freely switched between the normal state and the sound pickup state. Compared with the direct-through sound pickup channel in the traditional solution, in the normal state where sound pickup is not required, the microphone 3 of the active pen of the present application will be blocked due to the misalignment with the first sound pickup hole 131, thereby improving privacy and effectively reducing the risk of user privacy leakage; in addition, in the online meeting scenario, compared with the traditional solution of frequently moving the electronic device in order to achieve clear sound pickup for each participant, the microphone 3 is built into the active pen in the present application. In this way, in the online meeting scenario, only the active pen needs to be moved, and there is no need to move the electronic device. At the same time, since the active pen is very light, it is very convenient to move the active pen, which not only improves the meeting efficiency, but also does not affect the operation of the electronic device by the meeting host, and finally effectively improves the sound pickup range of the microphone 3 in the online meeting scenario.
