[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on November 30, 2023, with application number 202311649682.4 and title “Electronic Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application belongs to the technical field of electronic equipment, and specifically relates to an electronic equipment. Background Art

[0004] With the development of communication technology and the improvement of user needs, the size of mobile terminal display screens is getting larger and larger. Users hope that the mobile terminal screen is large enough, while at the same time they have higher and higher requirements for the thinness and lightness of mobile terminals. The two demands are contradictory. The folding screen perfectly solves this contradiction. While ensuring that the mobile terminal screen area is sufficient for use, the mobile terminal is made light, thin and compact enough, and the playability and portability are effectively improved.

[0005] A mobile terminal with a vertical folding screen refers to a mobile terminal that can be used as a normal-sized mobile terminal after the screen is unfolded along the long side (Y direction) of the mobile terminal, and is small enough to be easy to carry when folded. In order to improve practicality, the mobile terminal with a vertical folding screen is provided with a secondary screen near the camera on the battery cover, which enriches the interactive mode of the mobile terminal when the vertical folding screen is folded, so as to increase the user's usage rate of the mobile terminal when the vertical folding screen is in the folded state. The most important usage scenario is when the vertical folding screen is in the folded state and a call comes in, so that the user can answer the call without unfolding the vertical folding screen. However, in such a scenario, the phone goes directly into hands-free mode after answering, resulting in the leakage of user privacy and poor user experience. Summary of the Invention

[0006] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problems of user privacy leakage and poor user experience when a mobile terminal with a vertical folding screen answers a call with the vertical folding screen in a folded state.

[0007] In a first aspect, an embodiment of the present application provides an electronic device, including:

[0008] a first frame and a second frame connected by a rotating mechanism;

[0009] a first display screen, wherein the first display screen is a flexible display screen, covers the rotating mechanism, and is connected to the first frame and the second frame respectively; the first display screen can be switched between a folded state and an unfolded state by the rotating mechanism;

[0010] a first speaker, the first speaker comprising a speaker housing and a vibration unit, the vibration unit and the speaker housing forming a first cavity, a first sound outlet being provided on a side of the speaker housing facing away from the first display screen, the first sound outlet communicating with the first cavity;

[0011] a sound guide channel, one end of which is connected to the first sound outlet hole and the other end of which is close to the rotating mechanism;

[0012] Wherein, when the first display screen is in the folded state, the electronic device is in a call connected state, and a human ear is close to the rotating mechanism, the first sound wave signal transmitted from the first cavity is transmitted to the outside through the first sound outlet hole, the sound guide channel, and the second sound outlet hole in sequence; or,

[0013] When the first display screen is in the folded state, the electronic device is in a call connected state, and the human ear is away from the rotating mechanism, the second sound wave signal is transmitted to the outside through the first speaker or the second speaker.

[0014] In an embodiment of the present application, when the first display screen is in a folded state, the electronic device is in a call-connected state, and the human ear is close to the rotating mechanism, a first sound outlet hole connected to the first cavity is opened in the speaker shell of the first speaker, and the sound wave signal generated by the vibration unit during the call is guided from the first cavity and the first sound outlet hole to the vicinity of the rotating mechanism through the sound guide channel, thereby realizing a handle mode call instead of a hands-free mode call; when the first display screen is in a folded state, the electronic device is in a call-connected state, and the human ear is away from the rotating mechanism, the sound wave signal is transmitted to the outside through the first speaker or the second speaker, which can also realize a handle mode call instead of a hands-free mode call. Therefore, through the above-mentioned structural design, when the folding screen electronic device is in a folded state for a call, user privacy leakage can be avoided and the user experience is improved.

[0030] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0031] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "first," "second," and the like generally distinguish objects of a class and do not limit the number of objects. For example, the first object may be one or more.

[0032] The electronic device provided in the embodiments of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0033] As shown in Figures 1 to 14, the electronic device provided in the embodiment of the present application includes: a first frame body 2 and a second frame body 3 connected by a rotating mechanism 1; a first display screen 4, the first display screen 4 is a flexible display screen, the first display screen 4 covers the rotating mechanism 1, and is respectively connected to the first frame body 2 and the second frame body 3; the first display screen 4 can be switched between a folded state and an unfolded state through the rotating mechanism 1; a first speaker (51, 52), the first speaker (51, 52) includes a speaker housing 6 and a vibration unit 7, the vibration unit 7 and the speaker housing 6 form a first cavity 8, and the speaker housing 6 is provided with a first sound outlet 9 on a side facing away from the first display screen 4, and the first sound outlet 9 is connected to the first cavity 8; a sound guide channel 101, one end of the sound guide channel 101 is connected to the first sound outlet 9, and the other end is close to the rotating mechanism 1.

[0034] Here, the first frame 2 and the second frame 3 are used to support and accommodate other components. The first frame 2 and the second frame 3 can rotate relative to the rotation mechanism 1, thereby enabling the first display screen 4 to switch between a folded state and an unfolded state. The rotation mechanism 1 is used to connect the first frame 2 and the second frame 3, providing position limiting and guidance during connection and rotation. In some embodiments, the rotation mechanism 1 is a hinge assembly or a rotating assembly.

[0035] First display screen 4 is a flexible display screen that can be bent or folded. In some embodiments, the electronic device of the present application further includes a reinforcing steel sheet 25. Reinforcing steel sheet 25 is located where first display screen 4 covers the area of ​​rotating mechanism 1 and is bonded and fixed to first display screen 4. Reinforcing steel sheet 25 is used to protect first display screen 4 and ensure its flexible foldability.

[0036] In some embodiments, a camera is provided in the first frame 2, and the first speaker 51 is a speaker located in the first frame 2 and close to the camera, and is referred to as an upper speaker. In this case, the first speaker 51 is a single speaker.

[0037] In some embodiments, a camera is provided in the first frame 2 and a sub-board is provided in the second frame 3; the first speaker 52 is a speaker located in the second frame 3, called a lower speaker. In this case, the first speaker 52 is a speaker module.

[0038] In the embodiments of the present application, the upper speakers in the electronic device are uniformly numbered 51, and the lower speakers are uniformly numbered 52. That is, the first speaker in the present application can be the upper speaker 51 or the lower speaker 52. That is, the sound guide channel 101 can be set near the upper speaker 51 or the lower speaker 52. In the embodiments of the present application and the accompanying drawings, the first speaker 51 is used as the upper speaker, the second speaker 52 is used as the lower speaker, and the sound guide channel 101 is set near the upper speaker 51 as an example for explanation.

[0039] It should be understood that the first cavity 8 is referred to as the back cavity of the first speaker. A speaker is a sound-generating device that can convert an electrical signal into an acoustic signal.

[0040] When the first display screen 4 is folded, the electronic device is in a call-connected state, and the human ear is close to the rotating mechanism 1, the first sound wave signal transmitted from the first cavity 8 is transmitted to the outside through the first sound outlet 9, the sound guide channel 101, and the second sound outlet 100. In this case, the first speaker can be either the upper speaker 51 or the lower speaker 52.

[0041] Here, the first display screen 4 is in a folded state, and the user's ear is close to the rotating mechanism 1, that is, the user is holding the folded electronic device (see Figure 13). In some embodiments, whether the user's ear is close to the rotating mechanism 1 is determined by a sensor on the electronic device, such as a gravity sensor or gyroscope. Here, the gravity sensor can detect the electronic device's tilt and movement by detecting the electronic device's acceleration in the x, y, and z directions.

[0042] It should be noted that when the first display screen 4 is in a folded state, the electronic device is in a call connected state, and the human ear is close to the rotating mechanism 1, since the third sound outlet provided on the first display screen 4 is blocked inside the screen, the call cannot be made through the third sound outlet. In this embodiment of the present application, a first sound outlet 9 connected to the first cavity 8 is opened on the speaker shell 6, and the sound wave signal generated by the vibration unit 7 during the call is guided from the first cavity 8 and the first sound outlet 9 to the vicinity of the rotating mechanism 1 through the sound guide channel, thereby realizing a handle mode call rather than a hands-free mode call, which can avoid user privacy leakage and improve the user experience.

[0043] When the first display screen 4 is folded, the electronic device is in a call-connected state, and the human ear is away from the rotating mechanism 1, the second sound wave signal is transmitted to the outside through the first speaker (51, 52) or the second speaker. This can also achieve a handle mode call instead of a hands-free mode call, which can avoid user privacy leakage and improve the user experience. In this case, when the first speaker is the upper speaker 51, the second speaker is the lower speaker 52; when the first speaker is the lower speaker 52, the second speaker is the upper speaker 51.

[0044] Here, the first display screen 4 is in a folded state, and the human ear is away from the rotating mechanism 1 , that is, the user holds the electronic device in the folded state in reverse, see FIG. 14 .

[0045] If the first speaker is the upper speaker 51, then when the first display screen 4 is folded, the electronic device is in a call-connected state, and the human ear is away from the rotating mechanism 1, in order to obtain better call quality, the second sound wave signal is preferably transmitted to the outside through the second speaker 52 (i.e., the lower speaker). If the first display screen 4 is folded and the two sub-screens formed by the first display screen 4 are not tightly attached to each other, the second sound wave signal can also be transmitted to the outside through the first speaker 51 (i.e., the upper speaker).

[0046] If the first speaker is the lower speaker 52, that is, the sound guide channel 101 is set near the lower speaker, then when the first display screen 4 is in a folded state, the electronic device is in a call connected state, and the human ear is away from the rotating mechanism 1, the sound outlet of the lower speaker 52 is not blocked. In order to obtain better call quality, preferably, the second sound wave signal is transmitted to the outside through the first speaker 52 (i.e., the lower speaker). If the first display screen 4 is in a folded state and the two split screens formed by the first display screen 4 are not tightly fitted together, the second sound wave signal can also be transmitted to the outside through the second speaker 51 (i.e., the upper speaker).

[0047] Here, if the electronic device is provided with only the first display screen 4, when the first display screen 4 is in a folded state and a call comes in, the call can be answered by pressing a preset button.

[0048] In some embodiments, the electronic device further includes: a second display screen 10 , which is located on one side of the rotating mechanism 1 and is arranged opposite to the first display screen 4 , and the display surface of the second display screen 10 faces in the opposite direction to the display surface of the first display screen 4 .

[0049] Optionally, the second display screen 10 is provided on the first cover plate 17, and the first cover plate 17 is connected to the first frame body 2. Here, the first cover plate is the first battery cover. It should be understood that the second display screen 10 is the secondary screen provided on the first cover plate 17, and the first display screen 4 is the main screen. If the electronic device is provided with a first display screen 4 and a second display screen 10, then when the first display screen 4 is in a folded state and a call comes in, the user can connect the call by operating the second display screen 10, for example, by sliding input on the second display screen 10 to connect the call. In this way, combined with the above embodiments, it is possible to avoid user privacy leakage and enhance user experience, and it is also possible to further enrich the interaction mode of the electronic device when the first display screen 4 is in a folded state.

[0050] In some embodiments, the electronic device further includes a second cavity 12, wherein the second cavity 12 is formed by the vibration unit 7, the first frame 2, and the first display screen 4. Alternatively, the second cavity and the first cavity are formed by the vibration unit located in the speaker housing 6, separating the speaker housing 6. It should be understood that the second cavity is the front cavity of the first speaker.

[0051] Here, the second cavity 12 is formed by the vibration unit 7, the first frame 2 and the first display screen 4, which means that the first speaker 51 is an upper speaker, that is, the first speaker 51 is a speaker unit.

[0052] Among them, the second cavity 12 is formed by the vibration unit 7, the first frame 2 and the first display screen 4, the first display screen 4 is in the expanded state, see Figures 4 and 5, and the electronic device is in the call connected state, the third sound wave signal transmitted from the second cavity 12 is transmitted to the outside through the third sound outlet hole 11, and the fourth sound wave signal transmitted from the first cavity 8 is transmitted to the outside through the first sound outlet hole 9, the sound guide channel 101 and the second sound outlet hole 100 in sequence. The phase of the third sound wave signal is opposite to the phase of the fourth sound wave signal, and the third sound outlet hole 11 is set on the first display screen 4, see Figure 2.

[0053] It should be noted that since the third sound wave signal transmitted from the second cavity 12 is in opposite phase to the fourth sound wave signal transmitted from the first cavity 8, that is, the sound wave signals transmitted from the front and rear cavities of the first speaker 51 are in opposite phase, they will cancel each other out on the back of the electronic device (that is, the opposite side of the first display screen 4), see Figure 12. This will greatly reduce the leakage of call voice heard by people around the user, thereby ensuring the privacy of the user's call.

[0054] The first speaker 51 is an upper speaker. In some embodiments, referring to FIG1 , the electronic device further includes:

[0055] A support plate 13 is provided with a first through hole 14 at a position of the support plate 13 opposite to the first sound outlet 9. A first sealing strip 15 is provided on a side of the support plate 13 facing away from the first display screen 4. One end of the first sealing strip 15 surrounds the first through hole 14, and the other end extends to an edge of the support plate 13 near the rotating mechanism 1;

[0056] The target part is stacked with the support plate 13;

[0057] a first sealing ring 16 located between the target component and the support plate 13 , wherein the first sealing ring 16 is respectively attached to the target component and the support plate 13 , and the first sealing ring 16 surrounds the speaker housing 6 ;

[0058] The first cover plate 17 is connected to the first frame 2, and the first sealing strip 15 is in contact with the first cover plate 17;

[0059] The sound guide channel 101 includes a first sound guide channel and a second sound guide channel connected to the first sound guide channel. The support plate 13, the target component, and the first sealing ring 16 enclose the first sound guide channel, while the support plate 13, the first sealing strip 15, and the first cover plate 17 enclose the second sound guide channel. Specifically, one end of the second sound guide channel is connected to the first sound outlet 9, and the other end is close to the rotating mechanism 1.

[0060] Here, the first sound outlet hole 9 and the first through hole 14 are positioned relative to each other in order to achieve the communication between the first sound guide channel and the second sound guide channel.

[0061] It should be understood that the first sealing ring 16 is respectively attached to the target component and the support plate 13, and the three together form a space, namely the first sound guide channel.

[0062] The first sealing strip 15 is respectively attached to the support plate 13 and the first cover plate 17 , and the three together form a space, namely the second sound guide channel.

[0063] In some embodiments, the second sound outlet is provided on the bracket 200 opposite the other end of the rotating mechanism 1 and the sound guide channel 101. For example, if the rotating mechanism 1 is a hinge assembly, the bracket 200 is a hinged door panel. Thus, by providing the second sound outlet on the bracket 200, the sound guide channel 101 is opposite the second sound outlet, so that the sound wave signal guided by the sound guide channel 101 can be transmitted to the outside through the second sound outlet and heard by the human ear.

[0064] In some embodiments, the second sound outlet 100 is provided at a position corresponding to the other end of the first cover plate 17 and the sound guide channel 101, as shown in FIG11 . Thus, by providing the second sound outlet 100 on the first cover plate 17, the sound guide channel 101 corresponds to the position of the second sound outlet 100, so that the sound wave signal guided out of the sound guide channel 101 can be transmitted to the outside through the second sound outlet 100 and heard by the human ear.

[0065] The first cover plate 17 and the second cover plate 24 (hereinafter referred to as the second cover plate) are the back covers of the electronic device, used to support and protect other components. The first cover plate 17 houses the camera bezel 26 and the second display screen 10. Specifically, the first sealing strip 15 is provided with a first dust and water-proof mesh to achieve dust and water-proof functions.

[0066] In some embodiments, the target component is a mainboard 18 , the mainboard 18 is fixed to the support plate 13 , and the first speaker 51 is electrically connected to the mainboard 18 .

[0067] Here, the support plate 13 fixes and protects the main board 18. The main board 18 is used to realize the electrical connection of various devices and modules and provide various functions.

[0068] Optionally, the first speaker 51 is electrically connected to a first spring element provided on the mainboard 18 via a gold finger. That is, considering the thickness of the entire device and the rationality of the layout design of the internal components and wiring of the electronic device, when the first speaker 51 is the upper speaker, the first speaker 51 is not directly fixed to the mainboard 18, but is electrically connected to the first spring element provided on the mainboard 18 via a gold finger, and the mainboard 18 has a clearance area that matches the first speaker 51.

[0069] It should be noted that a first sealing ring 16 is provided between the mainboard 18 and the support plate 13 , and a second sealing ring (not shown) is provided between the first frame 2 and the mainboard 18 , so as to ensure that the electronic device is waterproof and dustproof.

[0070] In some embodiments, the target part is the first frame 2, which is connected to the first cover 17. That is, a first sealing ring 16 is provided between the first frame 2 and the support plate 13, but no sealing ring is required between the first frame 2 and the main board 18, which can save materials and costs.

[0071] In the following, the embodiments are described assuming that the first speaker 52 is the lower speaker.

[0072] In some embodiments, the vibration unit is located in the speaker housing 6 (in this case, the first speaker 52 is a speaker module, equivalent to a sealed box, and the vibration unit cannot be shown in the figure), and the speaker housing 6 is divided into the first cavity and the second cavity. That is, the second cavity and the first cavity are formed by the vibration unit located in the speaker housing 6, which separates the speaker housing 6. It should be understood that the second cavity is the front cavity of the first speaker 52. In this scenario, the first cavity and the second cavity cannot be shown in the figure.

[0073] Correspondingly, the speaker housing 6 is provided with a fourth sound outlet 19, see FIG6 , which is connected to the second cavity (i.e., the front cavity of the lower speaker 52); a fifth sound outlet 20 is provided on the side wall of the second frame 3 away from the rotating mechanism 1, see FIG2 ; the fifth sound outlet 20 is located opposite to the fourth sound outlet 19;

[0074] In some embodiments, when the first display screen 4 is in the folded state, the electronic device is in a call connected state, and the human ear is away from the rotating mechanism 1, the second sound wave signal is transmitted to the outside through the first speaker 52 (i.e., the lower speaker). The second sound wave signal includes the sixth sound wave signal and the seventh sound wave signal; the specific sound wave signal transmission is as follows:

[0075] The sixth sound wave signal transmitted from the second cavity (front cavity of the lower speaker) is transmitted to the outside through the fourth sound outlet 19 and the fifth sound outlet 20 in sequence, and the seventh sound wave signal transmitted from the first cavity (rear cavity of the lower speaker) is transmitted to the outside through the first sound outlet 9, the sound guide channel 101 and the second sound outlet 100 in sequence. The phase of the sixth sound wave signal is opposite to the phase of the seventh sound wave signal.

[0076] When the first display screen 4 is in a folded state, the electronic device is in a call connected state, and the human ear is away from the rotating mechanism 1, the second sound wave signal is transmitted to the outside through the first speaker 52 (i.e., the lower speaker). This is because the sound outlet of the lower speaker 52 is not blocked in this case, and better call quality can be obtained.

[0077] In addition, since the sixth sound wave signal transmitted from the second cavity is in opposite phase to the seventh sound wave signal transmitted from the first cavity, that is, the sound wave signals transmitted from the front and rear cavities of the first speaker 52 are in opposite phase, they will cancel each other out on the back of the electronic device (that is, the opposite side of the first display screen 4). This will greatly reduce the leakage of call voice heard by people around the user, thereby ensuring the privacy of the user's call.

[0078] In some embodiments, when the first display screen 4 is in the unfolded state and the electronic device is in a call connected state, the fifth sound wave signal is transmitted to the outside through the second speaker (ie, the upper speaker 51 ).

[0079] That is, when the first display screen 4 is in the unfolded state and the electronic device is in the call connected state, the upper speaker 51 is used to produce sound.

[0080] In some embodiments, the electronic device of the present application further includes:

[0081] The sub-board 21 and the first speaker 52 are electrically connected to the sub-board 21 , and a side of the speaker housing 6 close to the first display screen 4 covers the sub-board 21 .

[0082] Specifically, the sub-board 21 is electrically connected to the main board 18 through the flexible circuit board 22, thereby realizing electrical connection between the main board 18 including but not limited to the lower speaker, the first battery 23, the bottom antenna, etc.

[0083] A second cover plate 24 connected to the second frame 3 has a second sealing strip (not shown in the figure, the design of which can be referred to the first sealing strip) provided on one side of the second cover plate 24 close to the sub-plate 21. One end of the second sealing strip surrounds the first sound outlet, and the other end extends to the edge of the second cover plate 24 close to the rotating mechanism 1.

[0084] A first battery 23, the first battery 23 is connected to the sub-board 21, and a side of the first battery 23 facing away from the first display screen 4 and a side of the speaker housing 6 facing away from the sub-board 21 are located in the same plane;

[0085] The second cover plate 24 , the second sealing strip, the first battery 23 and the first speaker 52 are arranged to form the sound guide channel 101 .

[0086] It should be understood that the second sealing strip is attached to the second cover 24, the first battery 23 and the first speaker 52, and the four together form a space, namely the sound guide channel 101. Specifically, a second dustproof and waterproof net is provided on the second sealing strip, the purpose of which is to achieve waterproof and dustproof functions.

[0087] In some embodiments, the second sound outlet hole is provided at a position on the second cover plate 24 corresponding to the other end of the sound guide channel 101. Thus, by providing the second sound outlet hole on the second cover plate 24, the sound guide channel 101 corresponds to the position of the second sound outlet hole, so that the sound wave signal guided out of the sound guide channel can be transmitted to the outside through the second sound outlet hole and heard by the human ear.

[0088] If the first speaker 51 is the upper speaker, referring to FIG. 1 , the electronic device of the present application further includes: a third sealing ring 27 , which is sleeved on the first speaker 51 to block the first cavity 8 and the second cavity 12 .

[0089] Optionally, the electronic device of the present application further includes a fourth sealing ring 30 located between the fourth sound outlet 19 and the fifth sound outlet 20 .

[0090] Here, optionally, the first sealing strip 15 , the second sealing strip, the first sealing ring 16 , the second sealing ring, the third sealing ring and the fourth sealing ring 30 may all be made of foam, thereby achieving a waterproof effect.

[0091] Optionally, the electronic device of the present application further includes a second battery 28, which is disposed within the first housing 2 and electrically connected to the mainboard 18. Here, the first battery 23 and the second battery 28 are used to provide power, with the first battery 23 being connected to the sub-board 21 via a flexible circuit board (FPC), and the second battery 28 being electrically connected to the mainboard 18 via the FPC.

[0092] Optionally, the electronic device of the present application further includes a rear camera module 29, which is provided on the main board 18.

[0093] When the first display screen 4 is in different states and the user holds the electronic device in different states (such as forward grip or reverse grip), it is necessary to call the corresponding adaptive audio parameters through software and use the audio parameters to adjust the phase of the sound wave signal to achieve better call quality. In some embodiments:

[0094] When the first display screen 4 is in the unfolded state and the electronic device is in the call connected state, adjusting the phase of the sound wave signal using the first audio parameter;

[0095] When the first display screen 4 is in the folded state, the electronic device is in a call connected state, and the human ear is close to the rotating mechanism 1 (i.e., folded, held upright, and the call is connected), the phase of the sound wave signal is adjusted using the second audio parameter;

[0096] When the first display screen 4 is in the folded state, the electronic device is in a call connected state, and the human ear is away from the rotating mechanism 1 (i.e., folded, grip reversed, call connected), the phase of the sound wave signal is adjusted using the third audio parameter;

[0097] The first audio parameter, the second audio parameter and the third audio parameter are different.
