Detailed implementation manners

[0033] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0034] For example, electronic devices with folding functions such as mobile phones are favored by users because of their portability in the folded state and the ability to increase the screen size of the electronic device in the unfolded state.

[0035] Exemplarily, electronic devices with folding functions in the related art usually have two microphones. In the unfolded state, the two microphones are respectively located at the top and bottom of the electronic device. For example, the microphone at the bottom is used to pick up the user's voice, and the microphone at the top is used to pick up external sounds to achieve noise reduction for the electronic device. However, when the electronic device is in the folded state, the two microphones are located at the same end of the folded electronic device, and the two microphones will affect each other when picking up sounds, reducing the noise reduction effect and affecting the user experience.

[0036] To solve the above technical problems, the present disclosure provides an electronic device. The first folding portion includes a second region that is close to the second folding portion in the unfolded state. A first microphone and a sound pickup channel connected to the first microphone are provided in the first folding portion. The sound pickup channel includes a first sound pickup port and a second sound pickup port that are provided in the first region and face different directions. In the folded state, both the first sound pickup port and the second sound pickup port are exposed from the outer surface of the first region to achieve noise reduction of the electronic device. In the unfolded state, the second folding portion blocks the first sound pickup port, and the second sound pickup port is exposed from the outer surface of the first region. Thus, sound can be picked up through the second sound pickup port to achieve noise reduction of the electronic device. With such a design, the sound pickup of the first microphone is not limited by the usage state of the electronic device, improving the sound pickup effect of the first microphone. Therefore, the noise reduction effect of the electronic device using the first microphone can be effectively improved, and the user experience is enhanced.

[0037] An exemplary embodiment of the present disclosure provides an electronic device, which can be, for example, an electronic device with a folding function such as a mobile phone or a tablet computer, and the present embodiment does not limit this.

[0038] As Figure 1 and Figure 4 shown, the electronic device includes a first folding portion 1 and a second folding portion 2 that can be folded and unfolded with each other. The first folding portion 1 includes a first region that is close to the second folding portion 2 in the unfolded state. Exemplarily, as Figure 1 shown, the electronic device has opposite top and bottom edges in the unfolded state, and microphones can be provided on both the top and bottom edges. As Figure 4 shown, when the electronic device is in the folded state, the top edge and the bottom edge are close to each other and are located on the same side of the folded electronic device, and this side is opposite to the first region of the first folding portion 1.

[0039] As Figure 2 and Figure 3 shown, a first microphone 13 and a sound pickup channel 101 connected to the first microphone 13 are provided in the first folding portion 1. The sound pickup channel 101 includes a first sound pickup port 1051 and a second sound pickup port 1061 that are provided in the first region and face different directions. Exemplarily, in the unfolded state, the first sound pickup port 1051 faces the direction of the second folding portion 2, and in the folded state, the second sound pickup port 1061 faces away from the direction of the second folding portion 2.

[0040] As Figure 5 and Figure 6 shown, in the folded state, both the first sound pickup port 1051 and the second sound pickup port 1061 are exposed from the outer surface of the first region, and sound is picked up through the first sound pickup port 1051 and the second sound pickup port 1061 to achieve noise reduction of the electronic device.

[0041] As Figure 3 shown, in the unfolded state, the second folding part 2 blocks the first sound pickup port 1051, and the second sound pickup port 1061 is exposed from the outer surface of the first area. Sound is picked up through the second sound pickup port 1061 to achieve noise reduction of the electronic device.

[0042] With such a design, the sound pickup of the first microphone 13 is not restricted by the usage state of the electronic device, improving the sound pickup effect of the first microphone 13, thus effectively improving the noise reduction effect of the electronic device using the first microphone 13, and further enhancing the user experience.

[0043] As Figure 3 、 Figure 6 and Figure 8 shown, in one embodiment, the first folding part 1 includes a first middle frame 10 and a first back shell 11, the second folding part 2 includes a second middle frame 20, the first middle frame 10 includes a first surface 105 opposite to the second middle frame 20 in the unfolded state, and a second surface 106 facing the first back shell 11. The first microphone 13 is disposed on the second surface 106 of the first middle frame 10 facing the first back shell 11, and the sound pickup channel 101 is disposed in the first middle frame 10. In this way, while facilitating the processing of the sound pickup channel 101, it avoids the influence of the setting of the sound pickup channel 101 on the internal components of the electronic device, thus improving the reliability of the electronic device.

[0044] The first sound pickup port 1051 is disposed on the first surface 105. With such a design, it is convenient for the second middle frame 20 to block the first sound pickup port 1051 in the unfolded state. The second sound pickup port 1061 is disposed on the first middle frame 10. Exemplarily, the first middle frame 10 includes a middle frame body and a frame disposed on each edge of the middle frame body. The plurality of frames include a first frame that is close to each other in the unfolded state. The first frame includes a first surface 105 opposite to the second middle frame 20 in the unfolded state and an outer surface connected to the first surface 105. This outer surface is opposite to the second middle frame 20 in the folded state, and the second sound pickup port 1061 is located on this outer surface.

[0045] With such a setting form, in both the unfolded state and the folded state, the second sound pickup port 1061 can be exposed. In this way, the sound pickup of the first microphone 13 is not restricted by the usage state of the electronic device, improving the sound pickup effect of the first microphone 13, thus effectively improving the noise reduction effect of the electronic device using the first microphone 13, and further enhancing the user experience.

[0046] In another embodiment, the second sound pickup port 1061 is disposed on the first back shell 11. In this way, in both the unfolded state and the folded state, the second sound pickup port 1061 can be exposed, thereby improving the noise reduction effect of the electronic device using the first microphone 13.

[0047] In another embodiment, as Figure 6 shown, the gap between the first back shell 11 and the first middle frame 10 forms a second sound pickup port 1061. Exemplarily, a gap is generated between the first back shell 11 and the first frame of the first middle frame 10, and this gap forms the second sound pickup port 1061. With such a setting form, there is no need to open a hole in the first folding part 1, which improves the integrity of the first folding part 1, and thus can effectively improve the aesthetic appearance of the electronic device.

[0048] As Figure 3 shown, in one embodiment, a first groove 102 is provided on the second surface 106 of the first middle frame 10, the first microphone 13 is disposed in the first groove 102, and the sound pickup channel 101 is connected to the first groove 102. With such a setting form, on the one hand, it can reduce the occupation of the space of the electronic device in the thickness direction by the first microphone 13, which is beneficial to the thinning design of the electronic device. On the other hand, it can effectively avoid the influence of the first microphone 13 on the setting of the first back shell 11, effectively improving the flatness of the first back shell 11, and thus further enhancing the user experience.

[0049] Continuing to refer to Figure 3 , in one embodiment, the first middle frame 10 further includes a third surface 107 opposite to the second surface 106, a through hole 104 penetrating the third surface 107 is provided at the bottom of the first groove 102, and a second groove 103 is provided on the third surface 107. The second groove 103 is disposed closer to the first surface 105 than the first groove 102.

[0050] The first folding part 1 further includes a first seal 14. The first seal 14 can be, for example, a steel plate-like structural member. The first seal 14 is, for example, disposed on the third surface 107 by means of gluing or the like, and covers the through hole 104 and the second groove 103. At least a part of the first seal 14 has a gap with the third surface 107. Exemplarily, only a part of the first seal 14 may have a gap with the third surface 107, or the entire area of the first seal 14 may have a gap with the third surface 107, so that the second groove 103 can be connected to the through hole 104. By providing the first seal 14, local sealing of the sound pickup channel 101 can be achieved, avoiding sound leakage during the process of sound flowing from the sound pickup channel 101 into the first microphone 13, thereby effectively improving the sound pickup effect of the first microphone 13, and further improving the noise reduction effect of the electronic device. The way of forming the gap can be, for example, by providing a concave structure on the first seal 14, and this concave structure is recessed from the surface of the first seal 14 facing the third surface 107 in a direction away from the third surface 107. With such a design, the structure is simple and convenient for processing.

[0051] As Figure 3 andFigure 6 As shown, the sound pickup channel 101 includes a first channel 1011 and a second channel 1012. The first channel 1011 communicates with the first sound pickup port 1051 and the second groove 103, and the second channel 1012 communicates with the second sound pickup port 1061 and the second groove 103. The sound entering from the first sound pickup port 1051 enters the second groove 103 through the first channel 1011, and the sound entering from the second sound pickup port 1061 also enters the second groove 103 through the second channel 1012, and then is picked up by the second microphone through the through hole 104. With such a design, it is convenient to set the sound pickup channel 101, and the convenience of processing the sound pickup channel 101 is improved.

[0052] As Figure 3 shown, in one embodiment, the first channel 1011 communicates with the side wall of the second groove 103, and the second channel 1012 communicates with the bottom wall of the second groove 103. With such a setting form, the lengths of the first channel 1011 and the second channel 1012 can be shortened. While being convenient for processing, the structural strength of the first middle frame 10 can be effectively improved, thereby improving the reliability of the electronic device.

[0053] As Figure 3 and Figure 6 shown, in one embodiment, a blocking portion 30 is provided on the second middle frame 20. In the unfolded state, the blocking portion 30 can block the first sound pickup port 1051, and thus the first microphone 13 picks up sound only through the second sound pickup port 1061. With such a design, while the noise reduction effect can be improved, the sealing performance and integrity of the first folding portion 1 in the unfolded state are improved, thereby improving the aesthetics of the electronic device in the unfolded state and further enhancing the user experience.

[0054] In one embodiment, the blocking portion 30 is configured such that in the unfolded state, at least a part of the structure of the blocking portion 30 extends into the first sound pickup port 1051. Exemplarily, in the unfolded state, it may be that only a part of the structure of the blocking portion 30 extends into the first sound pickup port 1051, or the entire structure of the blocking portion 30 extends into the first sound pickup port 1051. In this way, the blocking effect on the first sound pickup port 1051 can be effectively improved. In the folded state, the exposed surface of the blocking portion 30 is flush with the outer surface of the second middle frame 20, thereby improving the flatness of the outer surface of the second middle frame 20 while avoiding damage to the blocking portion 30 due to external force factors, and thus effectively improving the reliability of the blocking portion 30.

[0055] In one embodiment, the blocking portion 30 is an elastic member, and the elastic member may be, for example, an elastic gel structure member. In the unfolded state, at least a part of the structure of the blocking portion 30 extends into the first sound pickup opening 1051, and the part extending into the first sound pickup opening 1051 is in interference fit with the first sound pickup opening 1051. With such a setting form, on the one hand, the blocking effect on the first sound pickup opening 1051 can be further improved. On the other hand, the friction between the blocking portion 30 and the first sound pickup opening 1051 can be effectively reduced, so that while improving the reliability of the electronic device, the generation of noise is reduced, and thus the user experience is effectively improved.

[0056] As Figure 3 and Figure 6 shown, in one embodiment, the electronic device further includes a hinge assembly, and the two folding portions are connected by the hinge assembly to switch between the unfolded state and the folded state. The hinge assembly includes a first support plate 51 slidably connected to the first middle frame 10 and a second support plate 52 slidably connected to the second middle frame 20. Both the first support plate 51 and the second support plate 52 are used to support the first screen 60. Exemplarily, the first screen 60 is disposed on the first middle frame 10 and the second middle frame 20. The first screen 60 may be, for example, a flexible screen, and the flexible screen can be folded and unfolded by flipping the first middle frame 10 and the second middle frame 20. During the unfolding and folding processes, the first support plate 51 and the second support plate 52 slide accordingly to support the first screen 60 located on the first middle frame 10 and the first screen 60 located on the second middle frame 20, respectively.

[0057] The first support plate 51 and the second support plate 52 are configured such that when switching from the folded state to the unfolded state, the first support plate 51 and the second support plate 52 move away from each other, and when switching from the unfolded state to the folded state, the first support plate 51 and the second support plate 52 move closer to each other. The blocking portion 30 is connected to the second support plate 52 through a link mechanism 40. The link mechanism 40 can move following the movement of the second support plate 52. When switching from the folded state to the unfolded state, the link mechanism 40 can drive the blocking portion 30 to move so that at least a part of the structure of the blocking portion 30 extends into the first sound pickup opening 1051. When switching from the unfolded state to the folded state, the link mechanism 40 can drive the blocking portion 30 to move so that the exposed surface of the blocking portion 30 is flush with the outer surface of the second middle frame 20.

[0058] With such a setting form, while facilitating the driving of the blocking portion 30, the structure is simple and easy to process. At the same time, the synchronism between the movement of the blocking portion 30 and the unfolding and folding processes of the electronic device is improved, avoiding the blocking portion 30 from affecting the normal unfolding and folding of the electronic device, thereby effectively improving the smoothness of unfolding and folding the electronic device and further enhancing the user experience.

[0059] Continue to refer to Figure 3 and Figure 6 In one embodiment, a slideway 201 is provided on the second middle frame 20. The link mechanism 40 includes a first link 41 and a second link 42. One end of the first link 41 is rotatably connected to the second support plate 52, and the other end of the first link 41 is rotatably connected to one end of the second link 42. The second link 42 is slidably engaged with the slideway 201. In the unfolded state, the slideway 201 is opposite to the first sound pickup port 1051. With such a setting form, on the one hand, the structure of the link mechanism 40 is simple, which is convenient for processing and reduces the failure rate of the link mechanism 40, thus effectively improving the reliability of the electronic device. On the other hand, by making the slideway 201 opposite to the first sound pickup port 1051 in the unfolded state, the smoothness of the second link 42 extending into or out of the first sound pickup port 1051 can be further improved. The blocking portion 30 is provided at the other end of the second link 42. For example, the blocking portion 30 can be provided at the other end of the second link 42 by means of adhesion or the like. With such a design, it is convenient to extend the blocking portion 30 into the first sound pickup port 1051, thereby improving the blocking effect of the first sound pickup port 1051.

[0060] In one embodiment, the blocking portion 30 covers the end face of the other end of the second link 42 and at least a part of the outer surface connected to the end face. Exemplarily, the blocking portion 30 can only cover the end face of the other end of the second link 42 and a part of the outer surface connected to the end face, or the blocking portion 30 can cover the end face of the other end of the second link 42 and all of the outer surfaces connected to the end face. After the second link 42 extends the blocking portion 30 into the first sound pickup port 1051, the blocking portion 30 on the outer surface of the second link 42 is in interference fit with the inner wall of the first channel 1011. With such a design, the blocking effect of the first sound pickup port 1051 can be further improved.

[0061] Such as Figure 7As shown, in one embodiment, the second middle frame 20 includes opposite fourth and fifth surfaces. In the folded state, the fourth surface faces the third surface 107 of the first middle frame 10. The second middle frame 20 is provided with a hollow structure 202 penetrating through the fourth and fifth surfaces of the second middle frame 20, and the flexible circuit board 15 of the electronic device passes through the hollow structure 202. The first link 41 passes through the hollow structure 202 and the flexible circuit board 15 to be connected to the second link 42. Exemplarily, the link mechanism 40 is disposed at the hollow structure 202, and the flexible circuit board 15 is provided with a through hole corresponding to the first link 41 for the first link 41 to pass through. With such a setting form, on the one hand, it can provide more space for the movement of the link mechanism 40, thus facilitating the driving of the blocking portion 30. On the other hand, disposing the link mechanism 40 at the hollow structure 202 of the second middle frame 20 reduces the occupation of the space in the thickness direction of the first folding portion 1, which is beneficial to the thinning design of the electronic device.

[0062] As Figure 3 As shown, in one embodiment, a second screen 12 is disposed between the first back shell 11 and the first middle frame 10. Exemplarily, the first back shell 11 can be provided with through holes to expose the second screen 12. Thus, in the folded state, display can be performed through the second screen 12 and the electronic device can be controlled, thereby effectively improving the usability of the electronic device and further enhancing the user experience. The first microphone 13 is disposed inside the second screen 12. It can be understood that the inside of the second screen 12 is the side of the second screen 12 facing the second surface 106 of the first middle frame 10. With such a setting form, by using the safety gap between the second screen 12 and the first middle frame 10, the first microphone 13 is disposed inside the second screen 12, so that the space in the thickness direction of the first folding portion 1 can be fully utilized, and thus the structure is more compact, which is beneficial to the miniaturization design of the electronic device.

[0063] In one embodiment, the first folding portion 1 further includes a second region that is away from the second folding portion 2 in the unfolded state. A second microphone is disposed inside the first folding portion 1, and the third sound pickup port of the second microphone is located in the second region. Exemplarily, the third sound pickup port can be located on the surface of the second region that faces away from the second folding portion 2 in the folded state, or can also be located on the surface of the second region that is away from the second folding portion 2 and faces the second folding portion 2 in the unfolded state. The second folding portion 2 includes a third region that is away from the first folding portion 1 in the unfolded state. A third microphone is disposed inside the second folding portion 2, and the fourth sound pickup port of the third microphone is located in the third region. Exemplarily, the fourth sound pickup port can be located on the surface of the third region that faces away from the first folding portion 1 in the folded state, or can also be located on the surface of the third region that is away from the first folding portion 1 and faces the first folding portion 1 in the unfolded state.

[0064] In the unfolded state, sound is picked up through the second sound pickup port 1061, the third sound pickup port, and the fourth sound pickup port.
