Description

Electronic device

[0001] The present application claims priority from the Chinese patent application No. 202410673959.5 filed on May 27, 2024, and entitled "Electronic device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of wireless communication, in particular to an electronic device. BACKGROUND

[0003] Currently, electronic devices support more and more functions, and the number of antennas also increases. The performance of the antennas directly affects the communication signals and network quality of the electronic devices, and plays a crucial role in user experience.

[0004] Currently, multiple antennas of an electronic device are arranged around the frame of the device, and the multiple antennas can be separated by insulating gaps. For example, a metal frame is used as part of an antenna, and the metal frame is separated into multiple sections that are electrically isolated from each other by multiple gaps. Each section can be reused as an antenna branch to transmit and receive radio frequency signals. The multiple antennas can also be switched with each other to avoid being held by a user.

[0005] In related technologies, the holding position of the user on the frame is detected through the touch screen on the front of the mobile phone, and then the antenna can be switched or smartly tuned according to the detection result. However, the touch screen is mainly used to detect touch actions on the front of the mobile phone, and the detection capability of holding and touching the antenna is very limited, and the detection accuracy is low. The above reasons further result in low accuracy and precision of controlling the antenna in the hand-holding case, which affects the communication performance of the antenna. SUMMARY

[0006] Embodiments of the present application provide an electronic device that can improve the accuracy of touch detection, achieve high-accuracy and high-precision control of an antenna assembly, and minimize the impact of user hand-holding on communication performance.

[0007] In a first aspect, an electronic device is provided, comprising: an antenna assembly comprising a first antenna branch; a touch screen configured to detect a touch action of a user on the electronic device and adjacent to the first antenna branch; a touch sensor configured to detect the touch action of the user on the electronic device and adjacent to the first antenna branch; and a processor configured to control the antenna assembly according to the detection of the touch screen and the touch sensor.

[0008] The electronic device provided by the embodiments of the present application is additionally provided with a touch sensor, and the touch screen and the touch sensor are simultaneously used to detect the touch action of the user on the first antenna branch. Compared with the prior art in which only the touch screen is used to detect the touch action of the user, the present application can improve the accuracy of touch detection, for example, the holding position recognition can be realized to the level of 1 millimeter. On this basis, the processor can simultaneously control the antenna assembly according to the detection signals of the touch screen and the touch sensor, thereby improving the accuracy and precision of the control of the antenna assembly, for example, helping to realize accurate and timely antenna branch switching and / or high-precision intelligent tuning. Thus, the electronic device provided by the present application can minimize the influence of the user's hand holding on the communication performance, ensure that the antenna assembly always has a better working state, and help to improve the user's experience.

[0009] Here, the touch screen and the touch sensor detect the touch action of the user on the electronic device and adjacent to the first antenna branch. It can also be understood that the touch action of the user on the electronic device and adjacent to the first antenna branch is detected. The touch action here can be any action that will affect the communication performance of the first antenna branch, for example, it can be a touch action, a proximity action or a holding action (such as the aforementioned death grip or virtual grip, etc.) of the user on the electronic device and adjacent to the first antenna branch, but is not limited thereto. The touch action here can be an active touch action of the user on the electronic device, or an unconscious touch action. It can be an action of the user on the surface of the electronic device (the user contacts the surface of the electronic device), or an action of the user near the surface of the electronic device (the user does not contact the surface of the electronic device, for example, the aforementioned "hover touch"). In addition, the touch action here can be an action of the user's hand on the electronic device, or an action of the user's body or head on the electronic device.

[0010] Here, the "touch action adjacent to the first antenna branch" refers to a touch action in the vicinity of the first antenna branch that will affect the communication performance. For example, the touch action adjacent to the first antenna branch can be a touch action within a certain range around the first antenna branch, for example, a touch action with a distance of 5 mm, 15 mm, 20 mm or 35 mm from the first antenna branch. It is easy to understand that the above-mentioned touch action is detected by the touch screen and the touch sensor, and therefore should have a detection capability corresponding to the above-mentioned distance range.

[0011] In some examples, the touch screen detects a touch action of a user on the electronic device and adjacent to the first antenna branch to generate a first detection signal; the touch sensor detects the touch action of the user on the electronic device and adjacent to the first antenna branch to generate a second detection signal; and the processor controls the antenna assembly according to the first detection signal and the second detection signal. Since the processor can control the antenna assembly according to the detection signals of the touch screen and the touch sensor at the same time, the accuracy and precision of the control of the antenna assembly can be improved.

[0012] In some examples, the touch action adjacent to the first antenna branch can be a touch action within a certain range of the periphery of the first antenna branch, for example, a touch action within 20 mm of the periphery. In addition, according to different sensing accuracy, the touch screen and / or the touch sensor can sense a touch action within, for example, 30 mm or 20 mm of the periphery. The embodiments of the present application are described by taking the certain range as 20 mm of the periphery as an example, and are not understood as a limitation on the sensing accuracy of the touch screen and / or the touch sensor, but are used to describe the use scenarios of the embodiments of the present application to facilitate understanding.

[0013] In some examples, although the touch screen and the touch sensor can detect a touch action within 20 mm of the periphery, the touch action adjacent to the first antenna branch detected by the touch screen and the touch sensor can be an action of the user contacting or touching the first antenna branch. The processor can control the antenna assembly based on the detection signals of the touch screen and the touch sensor on the above action, for example, switch the strip antenna branch.

[0014] In some examples, the touch screen and the touch sensor detecting the touch action of the user on the first antenna branch can be detecting whether the first antenna branch is held by the user, or detecting the distance (i.e., the closeness) between the touch action and the first antenna branch, or detecting whether the holding of the first antenna branch by the user is a death grip or a virtual grip, etc.

[0015] In some examples, the touch screen and the touch sensor detecting the touch action of the user on the first antenna branch can be detecting whether the first antenna branch is held by the user, and in the case of being held, detecting the holding position of the first antenna branch by the user, the tightness (pressure) of the holding, the length of the holding, or the area of the holding, etc.

[0016] In a possible implementation, the electronic device includes a housing, the touch screen is mounted on the housing, and the first antenna branch is part of the housing or is located in the housing. Through the above arrangement, the flexibility of the antenna arrangement can be improved, and the difficulty of the antenna design can be reduced.

[0017] In a possible implementation, the shell includes a conductive frame, and the first antenna branch includes at least a part (for example, at least one section) of the conductive frame. That is, at least part of the conductive frame can also be reused as the first antenna branch, so as to reduce the space occupied by the antenna assembly, ensure that the antenna branch has good radiation performance, and facilitate reduction of the difficulty of antenna design.

[0018] For example, the first antenna branch can include at least one section of the conductive frame. Here, the section can be a section between two slots, a section between two grounding points, or a section between a slot and a grounding point. The section can be provided with a feeding point to serve as a main feeding antenna, or can not be provided with a feeding point to serve as a parasitic antenna, which is not limited in the present application.

[0019] In a possible implementation, the shell includes an insulating frame, and the first antenna branch is located in the shell and adjacent to an inner wall of the insulating frame.

[0020] Through the above arrangement, the occupied area of the first antenna branch can be minimized, so that the first antenna branch is closer to the edge of the electronic device, and better radiation performance can be achieved. In addition, since no slot needs to be formed on the frame, the integrity of the frame structure can be ensured, and the frame has sufficient structural strength.

[0021] It should be noted that the first antenna branch adjacent to the inner wall of the insulating frame can be fixed to the inner wall of the insulating frame by adhesion or other process means, can be closely arranged adjacent to the inner wall of the insulating frame, or can be arranged adjacent to the insulating frame with a small gap (for example, 0.01 mm to 2 mm) therebetween, which is not limited in the present application.

[0022] In some examples, the first antenna branch is arranged inside the shell and adjacent to the inner wall of the insulating frame. Here, adjacent can mean that the distance (for example, the minimum distance) between the first antenna branch and the insulating frame is greater than or equal to 0 and less than or equal to 5 mm. For example, the distance between the first antenna branch and the insulating frame can be less than or equal to 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, or 4 mm, for example, the distance between the first antenna branch and the insulating frame can be 0.01 mm, 0.02 mm, 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.5 mm, 0.8 mm, 1 mm, 1.5 mm, 2 mm, 3 mm, or 4 mm, but is not limited thereto.

[0023] In some examples, the first antenna branch can be in the form of an antenna of a flexible printed circuit (FPC), an antenna of laser direct structuring (LDS), an antenna of microstrip antenna (MDA), or an antenna of printing direct structuring (PDS), etc.

[0024] In some examples, the first antenna branch can be disposed between the insulating frame and the battery.

[0025] In a possible implementation, the shell includes an insulating back cover, and the first antenna branch is located in the shell and disposed adjacent to an inner wall of the insulating back cover.

[0026] With the above arrangement, the occupied area of the first antenna branch can be minimized, so that the first antenna branch is closer to the edge of the electronic device, and better radiation performance can be achieved. Moreover, since no slot needs to be formed on the frame, the integrity of the frame structure can be ensured, and the frame has sufficient structural strength.

[0027] It should be noted that the first antenna branch adjacent to the inner wall of the insulating back cover mentioned herein can be that the antenna branch is fixed to the inner wall of the insulating back cover by adhesion or other process means; can also be that the antenna branch is disposed close to the inner wall of the insulating back cover; or can also be that the antenna branch is disposed close to the insulating back cover, but there is a small gap (for example, 0.01 mm to 2 mm) between them, which is not specially limited in the present application.

[0028] In some examples, the first antenna branch is disposed inside the shell and adjacent to the inner wall of the insulating back cover. Here, adjacent can mean that the distance (for example, the minimum distance) between the first antenna branch and the insulating back cover is greater than or equal to 0 and less than or equal to 5 millimeters (mm). For example, the distance between them is less than or equal to 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, or 4 mm, etc. For example, the distance between them can be 0.01 mm, 0.02 mm, 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.5 mm, 0.8 mm, 1 mm, 1.5 mm, 2 mm, 3 mm, or 4 mm, etc., but is not limited thereto.

[0029] In some examples, the first antenna branch can also be embedded in the insulating back cover, or disposed on the outside of the insulating back cover, for example, disposed in the camera decoration sheet.

[0030] In some examples, the first antenna branch at this time can be in the form of an antenna of an FPC, an antenna of an LDS, an antenna of a microstrip antenna MDA, or an antenna of a PDS, etc.

[0031] In some examples, the first antenna branch can be arranged between the insulating back cover and the battery.

[0032] In some examples, the interior of the insulating back cover can be provided with a recess, and the first antenna branch can be arranged in the recess.

[0033] In a possible implementation, the touch sensor is arranged adjacent to a first feeding point of the first antenna branch.

[0034] When the feeding point of the antenna branch is held by the user's hand, it will have a great influence on the communication performance of the antenna branch. The touch sensor of the present application is arranged adjacent to the first feeding point of the first antenna branch, which can be used to detect whether the first feeding point is held by the user's hand, and helps to realize high-accuracy and high-precision control of the antenna assembly, further reduces the influence of the user's hand on the communication performance, and improves the user's experience.

[0035] In some examples, the touch sensor arranged adjacent to the first feeding point can be that the orthographic projection of the touch sensor on the conductive frame covers the first feeding point. Alternatively, the orthographic projection of the touch sensor on the conductive frame can not coincide with (be staggered with) the first feeding point, and the distance between the proximal edge of the orthographic projection and the first feeding point is less than a certain threshold value, which can be 0.1 mm to 15 mm, for example, 0.5 mm, 1 mm, 2 mm, 3 mm, 5 mm, 8 mm, 10 mm, or 12 mm, etc.

[0036] In some examples, the touch sensor can be a touch panel, which can be a strip-shaped structure extending along the conductive frame. The sensing surface of the touch panel faces outward of the device, for example, towards the conductive frame, or can also face the back cover. The length of the strip-shaped structure can be greater than or equal to 0.2 cm, for example, 0.35 cm, 0.5 cm, 0.8 cm, 1.0 cm, 1.2 cm, 1.5 cm, 1.8 cm, or 2 cm, etc., so as to be able to better identify the touch position.

[0037] In a possible implementation, the touch sensor is arranged adjacent to an open end of the first antenna branch.

[0038] As a part of the antenna branch that plays a major role in radiation, when the open end is held by the user's hand, it will have a great impact on the communication performance of the antenna branch. The touch sensor in the application is arranged adjacent to the open end of the first antenna branch, which can be used to detect whether the open end of the first antenna branch is held by the user's hand, and helps to realize high accuracy and high precision control of the antenna assembly, which can further reduce the impact of the user's hand on the communication performance and improve the user's experience.

[0039] In a possible implementation, the antenna assembly further includes a second antenna branch, and the second antenna branch has a gap with the open end of the first antenna branch, and the touch sensor is arranged adjacent to the gap.

[0040] When the gap between the adjacent antenna branches is held by the user's hand, it will have a great impact on the communication performance of the antenna branch. The touch sensor in the application is arranged adjacent to the gap between the first antenna branch and the second antenna branch, which can be used to detect whether the gap is held by the user's hand, and helps to realize high accuracy and high precision control of the antenna assembly, which can further reduce the impact of the user's hand on the communication performance and improve the user's experience.

[0041] In some examples, the touch sensor is arranged adjacent to the gap, which can be that the orthographic projection of the touch sensor on the conductive frame covers the gap. Alternatively, the orthographic projection of the touch sensor on the conductive frame can not overlap (be staggered with each other) with the gap, and the distance between the proximal edge of the orthographic projection and the gap is less than a certain threshold, which can be 0.1 mm to 15 mm, for example, 0.5 mm, 1 mm, 2 mm, 3 mm, 5 mm, 8 mm, 10 mm or 12 mm, etc.

[0042] In a possible implementation, the touch sensor is arranged adjacent to the strongest current position of the first antenna branch.

[0043] When the strongest current position of the antenna branch is held by the user's hand, it will have a great impact on the communication performance of the antenna branch. The touch sensor in the application is arranged adjacent to the strongest current position of the first antenna branch, which can be used to detect whether the strongest current position is held by the user's hand, and helps to realize high accuracy and high precision control of the antenna assembly, which can further reduce the impact of the user's hand on the communication performance and improve the user's experience.

[0044] In a possible implementation, the touch sensor and the first antenna branch are insulated from each other or electrically connected to each other.

[0045] For example, the two can be insulated from each other, at which time the two are independent of each other and do not affect each other, and the touch sensor is only used to detect the touch action. Alternatively, the two can also be electrically connected to each other, at which time the touch sensor can also be reused as part of the antenna branch for communication, thereby making the antenna design of the present application more flexible.

[0046] Here, the insulation between the touch sensor and the first antenna branch means that the two are insulated from each other, physically separated, and separated by air or insulating material. It does not mean that there is no induced current between the two. In other words, in some examples, an induced current can be generated between the touch sensor and the first antenna branch, which is not specially limited by the present application.

[0047] In a possible implementation, the processor controls the antenna assembly according to the detection signal, including any one of the following controls: controlling the antenna assembly to switch the antenna branches; controlling the tuning circuit of the antenna assembly; controlling the antenna assembly to adjust the power of the first antenna branch.

[0048] In a possible implementation, the antenna assembly includes a plurality of antenna branches, and the touch sensor has a plurality of touch sensors, and the touch screen and the plurality of touch sensors are used to jointly detect a touch action of a user acting on the electronic device and adjacent to the plurality of antenna branches, and generate a detection signal, and the processor controls the antenna assembly according to the detection signal.

[0049] The present application can detect the touch action near any antenna branch through the plurality of touch sensors corresponding to the plurality of antenna branches, and in combination with the detection signal of the touch screen, so that the processor can accurately identify which antenna branch or branches are held by the user, and thereby achieve high-accuracy and high-precision control of the antenna assembly, further reduce the influence of the user's holding on the communication performance, and improve the user's experience.

[0050] In some examples, the number of touch sensors is equal to the number of antenna branches of the antenna assembly, and the touch sensors are one-to-one corresponding to the antenna branches, and any touch sensor is used to detect the touch action near the corresponding antenna branch.

[0051] In some examples, the number of touch sensors is not equal to the number of antenna branches of the antenna assembly, for example, the number of touch sensors is less than the number of antenna branches of the antenna assembly, or the number of touch sensors is greater than the number of antenna branches of the antenna assembly, which is not specially limited by the present application.

[0052] In some examples, for the antenna branches that are not easy to be held by the user, the corresponding touch sensor can not be provided.

[0053] In some examples, a plurality of touch sensors can be provided for an antenna branch that has a relatively large impact on communication performance, for example, two touch sensors can be provided for a first antenna branch, one of which is provided adjacent to a first feed point of the first antenna branch, and the other of which is provided adjacent to a gap between the first antenna branch and a second antenna branch.

[0054] In a possible implementation, the processor is further configured to acquire information associated with a holding gesture of the user on the electronic device according to the detection signal. The processor can further control the electronic device according to the associated information, for example, control the antenna assembly or control the content displayed on the touch screen, so as to improve the user experience.

[0055] For example, the associated information can be information of a user interface (UI) associated with the holding gesture, so that the processor can adjust the UI displayed on the touch screen according to the information, for example, adjust the position of a control, to facilitate better touch interaction of the user.

[0056] In a possible implementation, the touch sensor is a touch panel, for example, a capacitive touch panel or a resistive touch panel.

[0057] The touch panel is composed of a large number of touch detection units integrated at a high density, each of which can correspond to a detection area, so that the touch panel can not only detect whether the first antenna branch is touched by the user, but also detect the touch position and the touch area of the user, that is, detect the position, length or area of the first antenna branch held by the user, so that the processor can realize high-accuracy and high-precision control of the antenna assembly according to the detection signal, and further reduce the impact of the user holding on the communication performance.

[0058] In some examples, the touch sensor can be located inside or outside the shell of the electronic device. For example, the touch sensor is provided on the inner wall or the outer wall of the shell, or a part of the shell constitutes the touch sensor.

[0059] In a possible implementation, the touch panel includes a plurality of touch detection units, and the density of the plurality of touch detection units is greater than 2 pixel density units. For example, the density of the plurality of touch detection units can be 3ppi, 5ppi, 10ppi, 50ppi, 72ppi, 100ppi, 180ppi, 300ppi or 432ppi, etc.

[0060] In a possible implementation, the touch sensor is a touch pad, and the sensing surface faces the outer side of the electronic device to facilitate detection of the touch action of the user.

[0061] For example, the sensing surface faces the outer side of the device and is parallel or approximately parallel to the outer wall surface of the frame, thereby enabling detection of the touch action on the frame; or the sensing surface faces the outer side of the device and is parallel or approximately parallel to the outer wall surface of the back cover, thereby enabling detection of the touch action on the back cover.

[0062] In a possible implementation, the touch sensor is a touch pad, a fingerprint detection sensor, a pressure sensor, a light ray sensor, a proximity light sensor, a distance sensor, or an electromagnetic wave energy absorption ratio sensor. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0079] The embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below are examples for explaining the present application and should not be understood as limiting the present application.

[0080] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection" should be understood in a broad sense, for example, can be fixed connection, can be detachable connection, or integrally connected; can be mechanical connection, or electrical connection or can communicate with each other; can be directly connected, or indirectly connected through an intermediate medium; can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0081] In the description of the present application, it should be understood that the terms "upper", "lower", "side", "front", "back" and the like indicate the orientation or positional relationship based on the installation, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0082] Hereinafter, the terms "first", "second", and the like are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more features. In the description of the embodiments of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0083] The term "and / or" herein is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " herein generally represents that the front and rear associated objects are in an "or" relationship.

[0084] Electronic devices (such as mobile phones) with metal frames are favored by users because of their better appearance and texture, and have been widely popularized. The performance of the antenna directly affects the communication signal and network quality of the electronic device, and plays a crucial role in user experience.

[0085] The current metal frame is usually part of the antenna, and the metal frame is divided into multiple sections that are electrically isolated from each other by multiple slits. Each section can be reused as an antenna branch (radiator) to transmit and receive radio frequency signals, and each section can be used alternately to avoid being held by the user. For example, when the mobile phone is communicating through the lower section, if the section is being held by the user, it may cause serious attenuation of the antenna performance and cannot work normally, resulting in so-called "death grip". At this time, section switching can be performed to use the upper section of the mobile phone that is not held by the user to communicate, thereby avoiding the influence of the user's hand on the antenna performance and ensuring that the antenna always has better working performance.

[0086] In the related art, the user's holding position on the frame is detected through the touch screen on the front of the mobile phone, and then the antenna can be switched or smartly tuned according to the detection result to ensure communication quality.

[0087] Fig. 1 is a schematic diagram of an application scenario of detecting a user holding position through a touch screen. As shown in Fig. 1, the metal frame of a mobile phone is divided into multiple segments that are electrically isolated from each other, and multiple segments including a first segment 10 and a second segment 20 can be reused as antenna branches for communication. When the mobile phone is performing wireless communication through the first segment 10 located at the bottom, the holding position of the user can be detected through a touch screen 30 on the front of the mobile phone. The touch screen 30 has multiple detection areas arranged in an array along a touch plane (i.e., XY plane), and each square in Fig. 1 represents a detection area. Each detection area can detect the touch action of the user and generate a corresponding detection result. For example, the square with a gray background and containing the number "1" in Fig. 1 indicates that the detection area detects the touch action of the user, and the square with a white background and containing the number "0" in Fig. 1 indicates that the detection area does not detect the touch action of the user.

[0088] Subsequently, a processor inside the mobile phone identifies the holding position of the user according to the detection result from the touch screen 30 in combination with a preset algorithm (e.g., an artificial intelligence (AI) classification recognition algorithm), and determines that the first segment 10 is held by the user according to the identified holding position. At this time, the processor can perform segment switching to control the antenna to perform wireless communication using the second segment 20 located at the top of the mobile phone and not held by the user, thereby avoiding the influence of the user's hand holding on the performance of the antenna and improving the user experience.

[0089] However, the touch screen 30 is mainly used to detect the touch action on the front of the mobile phone, and has very limited detection capability for the frame part of the mobile phone, and the detection accuracy is low, for example, it cannot achieve a detection accuracy of 1 millimeter. The above reasons will further result in low accuracy and precision of controlling the antenna in the holding case, which will affect the communication performance of the antenna.

[0090] To solve the above problems, an electronic device additionally configured with a touch sensor is provided in the embodiments of the present application. The electronic device can detect the touch action of the user acting on the antenna branch (e.g., the first segment 10 or the second segment 20 described above) near the antenna branch through the touch screen and the touch sensor at the same time, thereby improving the accuracy of touch detection, for example, the holding position recognition can be achieved at a level of 1 millimeter. On this basis, the electronic device can control the antenna assembly according to the detection signals of the touch screen and the touch sensor at the same time, thereby improving the accuracy and precision of controlling the antenna assembly, for example, which is helpful to achieve accurate and timely antenna branch switching and / or high-precision intelligent tuning. Thus, the influence of the user's hand holding on the communication performance can be minimized, and the antenna assembly can always have a better working state, which is helpful to improve the user experience.

[0091] The electronic device provided in the embodiments of the present application may, for example, be any electronic product having a wireless communication function, such as a mobile phone, a tablet computer, an e-reader, a notebook computer, a vehicle-mounted device, a wearable device (for example, a watch, a bracelet, or glasses), a personal digital assistant (PDA), a point of sales (POS), a smart speaker, an augmented reality (AR) device, a virtual reality (VR) device, a mixed reality (MR) device, an industrial device, a video monitoring device, and the like. The mobile phone may, for example, be a conventional straight phone or a foldable phone, such as an up-and-down small foldable phone, a left-and-right inner foldable phone, or a left-and-right outer foldable phone. The embodiments of the present application take the mobile phone as an example for illustration.

[0092] FIG. 2 is a structural schematic diagram of the electronic device 100 provided in the embodiments of the present application, wherein part (a) of FIG. 2 is a front view of the electronic device 100, and part (b) of FIG. 2 is a rear view of the electronic device 100. FIG. 3 is a sectional view of the electronic device 100 provided in the embodiments of the present application.

[0093] As shown in FIGS. 2 and 3, the electronic device 100 provided in the embodiments of the present application includes a touch screen 110, a frame 120, and a back cover 130. The frame 120 and the back cover 130 form a housing of the electronic device 100, and the touch screen 110 is fixedly installed on the housing.

[0094] The touch screen 110 serves as a front panel of the electronic device 100 and forms, together with the housing, a mounting cavity for accommodating circuit boards, batteries, and other components. The touch screen 110 is used to provide human-computer interaction between a user and the electronic device 100, for example, to display images, videos, and other content to the user or to receive information input by the user (for example, to receive touch instructions of the user). The touch screen 110 may, in particular, include a touch panel (TP) and a display screen.

[0095] The touch panel can collect touch events (such as operations of the user using a finger, a stylus, or any suitable object on or near the touch panel) of the user of the electronic device 100 on or near the touch panel and send the collected touch information (touch data) to other components (for example, a processor). That is, the touch panel in the embodiments of the present application can collect touch events of the user acting on the touch panel, for example, such touch events can be generated when the finger of the user contacts the touch screen. In addition, the touch panel can also collect touch events of the user near the touch panel. At this time, the user can complete the touch operation without touching the screen, for example, the finger and the screen can be kept at a distance of about 15 millimeters to obtain similar mouse operations on the electronic device.

[0096] Here, a touch event near the touch panel by a user can be referred to as a hovering touch; the hovering touch can mean that the user does not need to directly contact the touch panel in order to select, move, or drag a target (e.g., an icon, etc.), but only needs to be located near the device in order to perform a desired function. In addition, the touch panel can be implemented in various types such as a resistive type, a capacitive type, an infrared type, and a surface acoustic wave type.

[0097] The display screen can be used to display information input by a user or information provided to the user. The touch panel can be overlaid on the display screen, and when the touch panel detects a touch event thereon or near thereto, the touch event can be transmitted to the processor to determine a type of the touch event, and then the processor can provide a corresponding visual output on the display screen according to the type of the touch event.

[0098] In some examples, the touch panel and the display screen are implemented as two separate components to perform input and output functions of the electronic device 100, and in other examples, the touch panel and the display screen can be integrated to perform input and output functions of the electronic device 100. It can be understood that the display screen is stacked by multiple layers of materials, and thus detailed descriptions thereof will not be provided in the embodiments of the present application.

[0099] In some examples, the display screen can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light emitting diode (AMOLED), a flex light-emitting diode (FLED), a Miniled, a MicroLed, a Micro-oLed, a quantum dot light emitting diodes (QLED) display screen, etc., but is not limited thereto.

[0100] In some examples, the touch screen 110 can be a multi-touch screen.

[0101] The bezel 120 is arranged around the touch screen 110 to help fix the touch screen 110. In the embodiment, the touch screen 110 is in a rectangular structure, and the bezel 120 includes four side edges connected end to end, which integrally form a hollow structure of a rectangle. One end face of the hollow structure is provided with the touch screen 110, and the other end face is provided with the back cover 130. In some examples, the bezel 120 has a chamfer, so that the bezel 120 has a more beautiful effect. The bezel 120 can be a metal bezel, for example, the material of the bezel 120 can include aluminum alloy, magnesium alloy, or stainless steel, etc. In addition, the bezel 120 can also be a non-metal bezel (i.e., an insulating bezel), which can be, for example, a plastic bezel, a resin bezel, a glass bezel, or a ceramic bezel, etc.

[0102] The back cover 130 can also be referred to as a back cover. The back cover 130 is a structure arranged opposite to the touch screen 110 on the electronic device 100, connected with the bezel 120, and used to encapsulate the components of the electronic device 100 inside the device. The back cover 130 can also prevent dust, prevent collision, and prevent hardware scratches. The back cover 130 can be a metal back cover (i.e., a metal back cover), or a non-conductive back cover (i.e., a non-metal back cover), such as a glass back cover, a plastic back cover, a ceramic back cover, etc. In addition, the back cover 130 can also be a porcelain back cover, i.e., a porcelain material formed by covering a porcelain glaze layer on a metal base is used as the back cover. The material of the back cover 130 is not limited in the embodiment.

[0103] In some examples, when the material forming the back cover 130 includes a conductive material such as metal, for example, when the back cover 130 is a metal back cover or a porcelain back cover, the back cover 130 can be used as a reference ground for electronic components or radio frequency components in the electronic device.

[0104] As shown in FIG. 3, the electronic device 100 provided by the embodiment of the present application further includes a middle plate 150. The middle plate 150 is a support frame located inside the electronic device 100, and the middle plate 150 can be made of a metal material and can be used as a ground (GND) of the electronic device 100.

The middle plate 150 and the frame 120 can be a separate structure or an integrated structure, and the embodiments of the present application are not limited. When the middle plate 150 and the frame 120 are a separate structure, the middle plate 150 and the frame 120 are two different components of the electronic device 100, and they can be assembled together by clamping, buckling or the like, and can be separated when disassembled. When the middle plate 150 and the frame 120 are an integrated structure, the connection relationship between the middle plate 150 and the frame 120 cannot be separated, for example, the middle plate 150 and the frame 120 are processed by one-piece molding, or are assembled by permanent connection such as bonding, welding, etc.

[0106] In some examples, the middle plate 150 is made of a conductive material such as metal, and the middle plate 150 is grounded, or the middle plate 150 is the reference ground. When the frame 120 is also made of a conductive material, the frame 120 can be electrically connected to the middle plate 150 to achieve grounding of the frame 120 through the middle plate 150. It can be understood that in other examples, the electronic device 100 can also not have a middle plate 150, and at this time the frame 120 can be connected to other grounding positions by a grounding member to achieve grounding.

[0107] As shown in FIG. 3, the frame 120 and the middle plate 150 are fixedly connected to form a middle frame structure of the electronic device 100, which is the middle part of the sandwich structure of the electronic device 100, and the two sides are used to carry the touch screen 110 and the back cover 130 respectively.

[0108] Specifically, the frame 120 and the back cover 130 form the shell of the electronic device 100, the back cover 130 is fixedly connected to the rear end face of the frame 120, and the touch screen 110 is fixedly connected to the front end face of the frame 120. The middle plate 150 is arranged in the shell, the touch screen 110 is fixedly attached to the front side of the middle plate 150, and the rear side of the middle plate 150 and the back cover 130 accommodate components such as the main board 500, the battery 600 and the small plate 700.

[0109] The main board 160, the battery 170 and the small plate 180 are sequentially arranged in the cavity between the middle plate 150 and the back cover 130 to form a traditional three-section design architecture, the main board 160 and the small plate 180 are electrically connected by a flexible printed circuit (FPC), and the flexible printed circuit can be clamped between the battery 170 and the back cover 130, or clamped between the battery 170 and the middle plate 150.

[0110] The mainboard 160 is an important component of the electronic device 100, on which various devices that constitute the circuit system of the electronic device 100 are installed. For example, the mainboard 160 is provided with main circuits, processors, chips, capacitors, resistors, inductors, interfaces, plug-ins and the like of the electronic device 100.

[0111] In some examples, the mainboard 160 can be provided with a system-on-a-chip (SOC) chip, a power management unit (PMU) chip or a radio frequency chip, and in addition, the mainboard 160 is usually provided with a central processing unit (CPU), various application processors (APs), graphics processing units (GPUs) or image signal processors (ISPs) and the like, but is not limited thereto.

[0112] The battery 170 is arranged in a battery compartment between the mainboard 160 and the small board 180. The battery 170 is an energy storage tool for providing power for the electronic device 100, and is usually composed of three parts of an electric core, a protection circuit and a shell. The battery 170 can be a lithium battery, a nickel-hydrogen battery or a sodium-ion battery, but is not limited thereto.

[0113] The small board 180 is arranged at the bottom end of the electronic device 100, and the small board 180 is usually provided with functional elements such as microphones, speakers, charging interfaces, USB interfaces, SIM card interfaces, radio frequency interfaces or antenna contacts. Some holes can be formed on the frame 120 and used in cooperation with the above-mentioned functional elements to realize the above-mentioned corresponding functions. For example, a charging port for inserting a charging plug into a charging interface can be formed on the frame 120. For another example, a sound outlet hole for the sound of the speaker to pass out can also be formed on the frame 120.

[0114] Further, the electronic device 100 provided by the embodiments of the present application further includes an antenna assembly, for example, the antenna assembly 200 in FIG. 4, and the electronic device 100 can realize wireless communication connection with other devices through the antenna assembly 200. FIG. 4 is a structural schematic diagram of the antenna assembly 200 provided by the embodiments of the present application. As shown in FIG. 4, the antenna assembly 200 can include one or more antennas, for example, the antenna assembly 200 can include one or more of a main antenna, a diversity antenna, a wireless fidelity (WIFI) antenna, a global positioning system (GPS) antenna, a bluetooth antenna, a multi input multi output (MIMO) antenna, and a near field communication (NFC) antenna.

[0115] In some examples, the antenna assembly 200 can include one or more of a monopole antenna, a planar inverted F-shaped antenna (PIFA), an inverted F-shaped antenna (IFA), a loop antenna, a slot antenna, a left-handed antenna, an Alpha antenna, a stand antenna, or a patch antenna.

[0116] As shown in FIG. 4, the antenna assembly 200 includes one or more antenna branches (which can also be referred to as antenna radiators or radiators) including the first antenna branch 201, and one or more radio frequency front-ends (RFFE) including the first radio frequency front-end 210.

[0117] The first antenna branch 201 is configured to radiate radio frequency signals to the outside world or receive radio frequency signals from the outside world, so that the electronic device 100 can communicate with the outside world through the first antenna branch 201. The first radio frequency front-end 210 is connected to the first antenna branch 201, and is configured to feed radio frequency signals to the first antenna branch 201 or receive radio frequency signals from the outside world received by the first antenna branch 201.

[0118] In some examples, the first radio frequency front end 210 includes a transmitting path and a receiving path. The transmitting path includes a power amplifier (PA), a filter, and the like, through which a signal is transmitted to the first antenna branch 201 after being processed by the power amplifier, the filter, and the like, and then transmitted to the outside world through the first antenna branch 201. The receiving path includes a low noise amplifier (LNA), a filter, and the like, through which a signal received by the first antenna branch 201 from the outside world is processed by the low noise amplifier, the filter, and the like, and then transmitted to the radio frequency chip, so as to realize wireless communication between the electronic device 100 and the outside world through the first radio frequency front end 210 and the first antenna branch 201.

[0119] In some embodiments, the first radio frequency front end 210 is arranged between the middle plate 150 and the back cover 130, for example, the first radio frequency front end 210 can be arranged on the main plate 160 or the small plate 180.

[0120] As shown in FIG. 4, the shape of the first antenna branch 201 can be a straight line, a broken line (for example, L-shaped), or other regular or irregular shapes, which are not limited in the present application. The first antenna branch 201 includes a first feeding point 211 and a first grounding point 212 arranged at intervals.

[0121] The first feeding point 211 is used to connect the first radio frequency front end 210, so that the radio frequency signal generated by the first radio frequency front end 210 can be transmitted to the first antenna branch 201 through the first feeding point 211, and then transmitted to the outside world through the first antenna branch 201, and also so that the first antenna branch 201 can transmit the radio frequency signal received from the outside world to the first radio frequency front end 210 through the first feeding point 211. It should be noted that the first feeding point 211 in the present application does not actually exist, and the position where the first radio frequency front end 210 is connected to the first antenna branch 201 is the first feeding point 211.

[0122] In some examples, the first radio frequency front end 210 is electrically connected to the first feeding point 211 through a wire (for example, a metal wire) and / or an electrical connector and the like.

[0123] The first grounding point 212 is used to realize grounding of the first antenna branch 201. By adjusting the position of the first grounding point 212, the electrical length of the first antenna branch 201 can be adjusted. The change in the electrical length can change the frequency at which the first antenna branch 201 resonates. In actual application, the first grounding point 212 can be realized by a grounding spring or a grounding wire. The first end of the grounding member is connected to the first grounding point 212, and the second end of the grounding member is connected to the reference ground. For example, the second end of the grounding member is electrically connected to the middle plate 150, and the grounding of the first antenna branch 201 is realized through the middle plate 150. It should be noted that the first grounding point 212 of the present application is not an actual point, and the position at which the grounding member such as the grounding spring or the grounding wire is connected to the first antenna branch 201 is the first grounding point 212.

[0124] In the embodiments of the present application, the positions of the first feeding point 211 and the first grounding point 212 on the first antenna branch 201 are not limited, as long as the first feeding point 211 and the first grounding point 212 are arranged at intervals along the extension direction of the first antenna branch 201.

[0125] In some examples, the first antenna branch 201 is electrically connected to the middle plate 150 through the first grounding point 212, and there can be a gap between the first antenna branch 201 and the middle plate 150 to ensure that the first antenna branch 201 has good clearance, so that the antenna assembly 200 has good radiation performance.

[0126] In some examples, the working frequency band of the first antenna branch 201 and / or the first radio frequency front end 210 can be any one of a satellite frequency band, a 2G frequency band, a 3G frequency band, a 4G frequency band, a 5G frequency band, a GPS frequency band, a WIFI frequency band, a Bluetooth frequency band, a star flash frequency band, or an NFC frequency band.

[0127] For example, the operating frequency band of the first antenna branch 201 and / or the first radio frequency front end 210 can be a high-orbit satellite communication frequency band (for example, 1980-2010 MHz or 2170-2200 MHz), a low-orbit satellite network frequency band (for example, 37.5-42.5 GHz or 47.2-51.4 GHz), a Beidou frequency band (for example, B1, B2, or B3 frequency band), B1, B2, B4, B5, B6, B8, or B19 frequency band of 3G; or can be B1, B2, B3, B4, B5, B7, B8, B12, B17, B18, B19, B20, B26, B28A, B34, B38, B39, B40, B41, or B42 frequency band of 4G; or can be N1, N3, N28A, N41, N77, N78, or N79 frequency band of 5G; or can be L1 frequency band of GPS or L5 frequency band of GPS; or can be 2.4G or 5G frequency band of WIFI, or 2.4G frequency band of Bluetooth, or 2.4G or 5G frequency band of Starlink.

[0128] In some examples, the first antenna branch 201 can be in any one of a PIFA antenna, a LOOP antenna, an IFA antenna, a SLOT antenna, and the like, but is not limited thereto.

[0129] As shown in FIG. 4, the antenna assembly 200 further includes a second antenna branch 202, which is used to radiate radio frequency signals to the outside world or receive radio frequency signals from the outside world, so that wireless communication between the electronic device 100 and the outside world can be realized through the second antenna branch 202. The second antenna branch 202 is arranged apart from the first antenna branch 201, and a gap 230 is formed therebetween. The gap 230 is used to isolate the adjacent second antenna branch 202 and the first antenna branch 201, so that they are completely insulated, thereby realizing isolation between different antenna branches. In some examples, the gap 230 can also be filled with insulating material, thereby increasing the insulation effect.

[0130] As shown in FIG. 4, the second antenna branch 202 can be in a zigzag shape (for example, L-shaped), or can be in a straight line shape or other regular or irregular shape, which is not limited in the present application. The second antenna branch 202 includes a second feeding point 221 and a second grounding point 222 arranged apart.

[0131] As shown in FIG. 4, the antenna assembly 200 further includes a second radio frequency front end 220, which is electrically connected to the second feeding point 221 of the second antenna branch 202. The second radio frequency front end 220 is used to feed radio frequency signals to the second antenna branch 202 or receive radio frequency signals received by the second antenna branch 202 from the outside world.

[0132] In some examples, the second radio frequency front end 220 includes a transmitting path and a receiving path. The transmitting path includes a power amplifier, a filter and the like, through which a signal is transmitted to the second antenna branch 202 after being processed by the power amplifier, the filter and the like, and is transmitted to the outside through the second antenna branch 202. The receiving path includes a low noise amplifier, a filter and the like, through which a signal received by the second antenna branch 202 from the outside is processed by the low noise amplifier, the filter and the like, and is transmitted to the radio frequency chip, so that the electronic device 100 and the outside can realize wireless communication through the second radio frequency front end 220 and the second antenna branch 202. It should be noted that the second feeding point 221 is not an actual point, and the position at which the second radio frequency front end 220 is electrically connected to the second antenna branch 202 is the second feeding point 221 according to the present application.

[0133] In some examples, the second radio frequency front end 220 is arranged between the middle plate 150 and the back cover 130, for example, the second radio frequency front end 220 can be arranged on the main plate 160 or the small plate 180.

[0134] The second grounding point 222 is used to realize the grounding of the second antenna branch 202, and the electrical length of the second antenna branch 202 can be adjusted by adjusting the position of the second grounding point 222. The change of the electrical length can change the frequency at which the second antenna branch 202 resonates. In actual application, the second grounding point 222 can realize grounding through a grounding spring or a grounding wire. The first end of the grounding member is connected to the second grounding point 222, and the second end of the grounding member is connected to the reference ground. For example, the second end of the grounding member is electrically connected to the middle plate 150, and the grounding of the second antenna branch 202 is realized through the middle plate 150. It should be noted that the second grounding point 222 is not an actual point, and the position at which the grounding spring or the grounding wire is connected to the second antenna branch 202 is the second grounding point 222.

[0135] In the embodiment of the present application, the positions of the second feeding point 221 and the second grounding point 222 on the second antenna branch 202 are not limited, as long as the second feeding point 221 and the second grounding point 222 are arranged at intervals along the extension direction of the second antenna branch 202. The related setting details of the second antenna branch 202 can be referred to the description of the first antenna branch 201, which will not be repeated here.

[0136] The present application sets the second antenna branch 202, so that the antenna assembly 200 provided by the embodiment can not only realize the transmission or reception of signals of the first frequency band through the first antenna branch 201, but also realize the transmission or reception of signals of the second frequency band through the second antenna branch 202, so that the application frequency band of the antenna assembly 200 is more, and the application range is more extensive.

[0137] In some examples, the antenna assembly 200 further comprises a tuning element electrically connected with the first antenna branch 201 and / or the second antenna branch 202, for enabling the resonant frequency of the first antenna branch 201 and / or the second antenna branch 202 to match the required communication frequency, for example, the intelligent tuning of the antenna assembly 200 can be realized through the tuning element. For example, the tuning element can comprise at least one component of capacitance, inductance, resistance, etc.

[0138] In some examples, the first antenna branch 201 and / or the second antenna branch 202 can be part of the housing of the electronic device 100 (i.e. part of the housing is multiplexed as an antenna branch), or the first antenna branch 201 and / or the second antenna branch 202 is located inside the housing of the electronic device 100. Through the above arrangement, the flexibility of the antenna arrangement can be improved, which is conducive to reducing the difficulty of antenna design.

[0139] In some examples, the bezel 120 can be made of conductive material, i.e. the bezel 120 is a conductive bezel (for example, a metal bezel), at this time, part of the bezel 120 can be used as the first antenna branch 201 and the second antenna branch 202, thereby reducing the space occupied by the antenna assembly 200, ensuring that the antenna branch has good radiation performance, and facilitating the reduction of the difficulty of antenna design.

[0140] FIG. 5 is a structural schematic diagram of an arrangement of an antenna branch according to an embodiment of the present application. As shown in FIG. 5, the bezel 120 can be a conductive bezel 120a, for example, a metal bezel such as an aluminum alloy, a magnesium alloy, or a stainless steel. At this time, the conductive bezel 120a can be used as part of the antenna assembly 200, that is, in addition to realizing the basic function of the housing, the conductive bezel 120a can be multiplexed as an antenna branch of the antenna assembly 200 for wireless communication.

[0141] Specifically, a plurality of slits 230 are formed on the conductive bezel 120a to divide the conductive bezel 120a into a plurality of segments that are electrically isolated from each other. By changing the number of slits 230, the number of segments can be changed. For example, the number of slits 230 formed on the conductive bezel 120a can be 3-15, for example, 5, 6, 7, or 8.

[0142] As shown in FIG. 5, in the embodiment, eight slits 230 are sequentially arranged on the conductive frame 120a, and the eight slits 230 divide the conductive frame 120a into eight sections, one of which forms the first antenna branch 201, another of which forms the second antenna branch 202, and the first antenna branch 201 and the second antenna branch 202 are separated by one of the slits 230. The remaining six sections form the third antenna branch 203, the fourth antenna branch 204, the fifth antenna branch 205, the sixth antenna branch 206, the seventh antenna branch 207, and the eighth antenna branch 208 of the antenna assembly 200, respectively.

[0143] In some examples, two or more of the sections of the conductive frame 120a can have the same operating frequency band. Alternatively, the operating frequency bands of the sections of the conductive frame 120a can be different from each other, which is not specially limited in the present application.

[0144] In some examples, all of the sections of the conductive frame 120a can be used as antenna branches. Alternatively, part of the sections (for example, one or two of the sections) can not be used as antenna branches, which is not specially limited in the present application.

[0145] In some examples, the multiple antenna branches of the antenna assembly 200 can all be located on the conductive frame 120a, that is, the multiple antenna branches are formed by the sections of the conductive frame 120a. Alternatively, part of the antenna branches of the antenna assembly 200 can not be located on the conductive frame 120a, that is, the part of the antenna branches are not formed by the sections of the conductive frame 120a, for example, the part of the antenna branches can be located inside the housing of the electronic device 100 and / or on the back cover 130, which is not specially limited in the present application.

[0146] For example, the antenna assembly 200 includes eight antenna branches, which are the first antenna branch 201, the second antenna branch 202, the third antenna branch 203, the fourth antenna branch 204, the fifth antenna branch 205, the sixth antenna branch 206, the seventh antenna branch 207, and the eighth antenna branch 208 in FIG. 5.

[0147] For another example, in addition to the eight antenna branches including the first antenna branch 201, the second antenna branch 202, the third antenna branch 203, the fourth antenna branch 204, the fifth antenna branch 205, the sixth antenna branch 206, the seventh antenna branch 207, and the eighth antenna branch 208 in FIG. 5, the antenna assembly 200 can further include other antenna branches, which can be arranged inside the housing of the electronic device 100 and / or on the back cover 130.

[0148] In some examples, the gap 230 is filled with an insulating material to make the appearance surface of the metal frame 120a neat and ensure the structural integrity of the frame 120. In addition, the two adjacent sections can be completely insulated, thereby achieving isolation between different antenna branches.

[0149] For example, the insulating material can be reliably arranged in the gap 230 by a nano-injection molding process.

[0150] FIG. 6 is a structural schematic diagram of another arrangement of an antenna branch according to an embodiment of the present application. As shown in FIG. 6, the aforementioned frame 120 can be an insulating frame 120b made of a non-conductive material, for example, a plastic frame, a resin frame, a glass frame, or a ceramic frame. At this time, the insulating frame 120b cannot be used for communication as part of the antenna assembly 200. Considering that the antenna branch needs to be arranged near the edge of the electronic device 100, the aforementioned first antenna branch 201 and / or the second antenna branch 202 can be arranged inside the housing and adjacent to (for example, close to) the inner wall of the insulating frame 120b in order to minimize the occupied area of the antenna branch and make the antenna branch closer to the edge of the electronic device 100, thereby achieving better radiation performance. In addition, at this time, since there is no need to open a gap on the frame, the structural integrity of the frame can be ensured, and the frame has sufficient structural strength.

[0151] It should be noted that the antenna branch (for example, the first antenna branch 201) adjacent to the inner wall of the insulating frame 120b can be fixed to the inner wall of the insulating frame 120b by adhesion or other process means; can be arranged close to the inner wall of the insulating frame 120b; or can be arranged close to the insulating frame 120b with a small gap (for example, 0.01 mm to 2 mm) between them, which is not specially limited by the present application.

[0152] In some examples, the first antenna branch 201 is arranged inside the housing and adjacent to the inner wall of the insulating frame 120b. Here, adjacent can mean that the distance (for example, the minimum distance) between the first antenna branch 201 and the insulating frame 120b is greater than or equal to 0 and less than or equal to 5 mm (millimeters). For example, the distance between them can be less than or equal to 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, or 4 mm, for example, the distance between them can be 0.01 mm, 0.02 mm, 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.5 mm, 0.8 mm, 1 mm, 1.5 mm, 2 mm, 3 mm, or 4 mm, but not limited thereto.

[0153] In some examples, the first antenna branch 201 and / or the second antenna branch 202 at this time can be in the form of an antenna of FPC, in the form of an antenna of laser direct structuring (LDS), in the form of an antenna of microstrip antenna (MDA), or in the form of an antenna of printing direct structuring (PDS), etc.

[0154] In some examples, the first antenna branch 201 and / or the second antenna branch 202 can be arranged between the insulating frame 120b and the battery 170.

[0155] FIG. 7 is a structural schematic diagram of another arrangement manner of an antenna branch provided by an embodiment of the present application. As shown in FIG. 7, the aforementioned back cover 130 can be an insulating back cover 130a made of a non-conductive material, for example, the insulating back cover 130a can be a glass back cover, a plastic back cover, a resin back cover, a ceramic back cover, or a non-metal back cover. At this time, considering that the antenna branch needs to be arranged at a position close to the edge of the electronic device 100, the present application can arrange the aforementioned first antenna branch 201 and / or the second antenna branch 202 inside the shell and adjacent to the inner wall of the insulating back cover 130a, so as to minimize the occupied area of the antenna branch, so that the antenna branch is closer to the edge of the electronic device 100, and better radiation performance can be achieved. Moreover, at this time, since there is no need to open a gap on the frame, the integrity of the frame structure can be ensured, and the frame has sufficient structural strength.

[0156] It should be noted that the antenna branch (for example, the first antenna branch 201) mentioned here adjacent to the inner wall of the insulating back cover 130a can be that the antenna branch is fixed on the inner wall of the insulating back cover 130a by means of adhesion or other process means; can also be that the antenna branch is arranged close to the inner wall of the insulating back cover 130a; can also be that the antenna branch is arranged close to the insulating back cover 130a, but there is a small gap (for example, 0.01-2 mm) between them, which is not specially limited by the present application.

[0157] In some examples, the first antenna branch 201 is disposed inside the housing and adjacent to an inner wall of the insulating back cover 130a. Here, adjacent can mean that the distance (e.g., minimum distance) between the first antenna branch 201 and the insulating back cover 130a is greater than or equal to 0 and less than or equal to 5 millimeters (mm). For example, the distance between the two can be less than or equal to 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, or 4 mm, etc. For example, the distance between the two can be 0.01 mm, 0.02 mm, 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.5 mm, 0.8 mm, 1 mm, 1.5 mm, 2 mm, 3 mm, or 4 mm, etc., but the present application is not limited thereto.

[0158] In some examples, the first antenna branch 201 and / or the second antenna branch 202 can also be embedded in the insulating back cover 130a or disposed outside the insulating back cover 130a, for example, in the camera decoration sheet.

[0159] In some examples, the first antenna branch 201 and / or the second antenna branch 202 at this time can be in the form of an FPC antenna, an LDS antenna, a microstrip antenna MDA, or a PDS antenna, etc.

[0160] In some examples, the first antenna branch 201 and / or the second antenna branch 202 can be disposed between the insulating back cover 130a and the battery 170.

[0161] In some examples, the interior of the insulating back cover 130a can be provided with a recess, and the first antenna branch 201 and / or the second antenna branch 202 can be disposed in the recess.

[0162] In some examples, the plurality of antenna branches of the antenna assembly 200 can all be located inside the housing and adjacent to the inner wall of the insulating back cover 130a, for example, all located on the inner wall of the insulating back cover 130a. Alternatively, part of the antenna branches of the antenna assembly 200 can not be located on the insulating back cover 130a. For example, the part of the antenna branches can be located inside the housing of the electronic device 100 and adjacent to the inner wall of the insulating frame 120b, or the part of the antenna branches can be located on the conductive frame 120a (i.e., the part of the antenna branches is composed of a segment of the conductive frame 120a), and the present application does not make special limitations thereto.

[0163] In other words, the embodiments shown in Figures 5 and 7 of this application can be combined with each other. At least one antenna branch of the antenna assembly 200 can be located on the conductive frame 120a, that is, at least one segment of the conductive frame 120a constitutes the at least one antenna branch, and at least one antenna branch of the antenna assembly 200 (e.g., the remaining antenna branches) can be located on the insulating back cover 130a. Alternatively, the embodiments shown in Figures 6 and 7 of this application can be combined with each other. At least one antenna branch of the antenna assembly 200 can be located inside the housing and disposed adjacent to the inner wall of the insulating frame 120b, and at least one antenna branch of the antenna assembly 200 (e.g., the remaining antenna branches) can be located on the insulating back cover 130a.

[0164] In some examples, as shown in Figure 7, multiple antenna stubs, including a first antenna stub 201, a second antenna stub 202, a third antenna stub 203, and a fourth antenna stub 204, are disposed on the inner wall of the insulating back cover 130a. These multiple antenna stubs avoid the through-hole 131 through which the camera 140 passes and are distributed at different positions on the insulating back cover 130a. The first antenna stub 201 and the second antenna stub 202 are adjacent to each other and spaced apart, separated by a gap 230, thereby making the antenna assembly 200 structurally compact and reducing the space occupied by the antenna assembly 200. The shapes and / or sizes of the different antenna stubs can be the same or different, and this application does not impose any special limitations on this.

[0165] Taking the antenna stub arrangement shown in Figure 5 as an example, the electronic device 100 provided in this application embodiment will be further described below with reference to the accompanying drawings. Figure 8 is a schematic diagram of an example of the circuit structure of the electronic device 100 provided in this application embodiment. As shown in Figures 5 and 8, the electronic device 100 provided in this application embodiment also includes a touch sensor 300 and a processor 400. The touch sensor 300 and the aforementioned touch screen 110 are both electrically connected to the processor 400.

[0166] The touch screen 110 is used to detect the user's touch action on the electronic device 100 and near the first antenna branch 201, the touch sensor 300 is used to detect the user's touch action on the electronic device 100 and near the first antenna branch 201, and the processor 400 is used to control the antenna assembly 200 based on the detection of the touch screen 110 and the touch sensor 300.

[0167] The electronic device 100 provided by the embodiments of the present application is additionally provided with the touch sensor 300, and the touch screen 110 and the touch sensor 300 are simultaneously used to detect the touch action of the user acting on the first antenna branch 201, compared with the prior art which only uses the touch screen to detect the touch action of the user, the present application can improve the accuracy of touch detection, for example, the holding position recognition of 1 millimeter level can be realized. On this basis, the processor 400 can simultaneously control the antenna assembly 200 according to the detection signals of the touch screen 110 and the touch sensor 300, so as to improve the accuracy and precision of the control of the antenna assembly 200, for example, to help realize accurate and timely antenna branch switching and / or high-precision intelligent tuning. Thus, the electronic device 100 provided by the present application can minimize the influence of the user's hand holding on the communication performance, ensure that the antenna assembly 200 always has a better working state, and help improve the user's experience.

[0168] Here, the touch screen 110 and the touch sensor 300 detect the touch action of the user acting on the electronic device 100 and adjacent to the first antenna branch 201, which can also be understood as detecting the touch action of the user acting on the electronic device 100 and located near the first antenna branch 201. The touch action here can be any action that will affect the communication performance of the first antenna branch 201, for example, it can be a touch action, a proximity action or a holding action (such as the aforementioned death grip or virtual grip, etc.) of the user acting on the electronic device 100 and located near the first antenna branch 201, but not limited to this. The touch action here can be an active touch action of the user on the electronic device, or an unconscious touch action, which can be an action of the user acting on the surface of the electronic device 100 (the user contacts the surface of the electronic device 100), or an action of the user near the surface of the electronic device 100 (the user does not contact the surface of the electronic device 100, for example, the aforementioned "hover touch"). In addition, the touch action here can be an action of the user's hand acting on the electronic device 100, and can also be an action of the user's body or head or other parts acting on the electronic device 100.

[0169] Here, the "touch action adjacent to the first antenna branch 201" refers to the touch action in the vicinity of the first antenna branch 201 that will affect the communication performance. For example, the touch action adjacent to the first antenna branch 201 can be the touch action within a certain range around the first antenna branch 201, for example, the touch action within 5mm, 15mm, 20mm or 35mm from the first antenna branch 201. It is easy to understand that the above-mentioned touch action is detected by the touch screen 110 and the touch sensor 300, and therefore should have a detection capability corresponding to the above-mentioned distance range.

[0170] In some examples, the touch screen 110 detects a touch action of a user acting on the electronic device 100 and adjacent to the first antenna branch 201 to generate a first detection signal; the touch sensor 300 detects a touch action of a user acting on the electronic device 100 and adjacent to the first antenna branch 201 to generate a second detection signal; and the processor 400 controls the antenna assembly 200 according to the first detection signal and the second detection signal. Since the processor 400 can control the antenna assembly 200 according to the detection signals of the touch screen 110 and the touch sensor 300 at the same time, the accuracy and precision of the control of the antenna assembly 200 can be improved.

[0171] In some examples, the touch action adjacent to the first antenna branch 201 can be a touch action within a certain range of the periphery of the first antenna branch 201, for example, a touch action within 20 mm of the periphery. In addition, according to different sensing accuracies, the touch screen 110 and / or the touch sensor 300 can sense a touch action within, for example, 30 mm or 20 mm of the periphery. The embodiments of the present application are described by taking the certain range as 20 mm of the periphery as an example, and are not understood as limiting the sensing accuracy of the touch screen 110 and / or the touch sensor 300, but are used to describe the use scenarios of the embodiments of the present application to facilitate understanding.

[0172] In some examples, the touch action adjacent to the first antenna branch 201 can be an action of a user contacting or touching the first antenna branch 201, and the processor 400 can control the antenna assembly 200 based on the detection signals of the touch screen 110 and the touch sensor 300 on the action, for example, to switch the antenna branches.

[0173] In some examples, the touch screen 110 and the touch sensor 300 detecting the touch action of the user acting on the first antenna branch 201 can be detecting whether the first antenna branch 201 is held by the user, or detecting the distance (i.e., the closeness) between the touch action and the first antenna branch 201, or detecting whether the holding of the first antenna branch 201 by the user is a death grip or a virtual grip, etc.

[0174] In some examples, the touch screen 110 and the touch sensor 300 detecting the touch action of the user acting on the first antenna branch 201 can be detecting whether the first antenna branch 201 is held by the user, and in the case of being held, detecting the holding position, the tightness (pressure) of the holding, the length or the area of the holding of the first antenna branch 201 by the user, etc.

[0175] In some examples, the touch sensor 300 can be any sensor capable of detecting a touch action of a user on the first antenna branch 201, such as a touchpad, a fingerprint detection sensor, a pressure sensor, an infrared light sensor, a proximity light sensor, a distance sensor, or a specific absorption rate (SAR) sensor, but is not limited thereto.

[0176] In some examples, the touch sensor 300 can be a touchpad, such as a capacitive touchpad or a resistive touchpad, which is composed of a large number of touch detection units integrated at a high density, each of which can correspond to a detection area, so that the touchpad can not only detect whether the first antenna branch 201 is touched by a user, but also detect the touch position and the touch area of the user, i.e., detect the position, length, or area of the first antenna branch 201 held by the user, so that the processor 400 can achieve high-accuracy and high-precision control of the antenna assembly 200 according to the detection signal, and further reduce the influence of the user's holding on the communication performance.

[0177] For example, the density of the plurality of touch detection units can be 3 pixels per inch (ppi), 5 ppi, 10 ppi, 50 ppi, 72 ppi, 100 ppi, 180 ppi, 300 ppi, or 432 ppi, etc.

[0178] In some examples, the touch sensor 300 can be located inside or outside the housing of the electronic device 100. For example, the touch sensor 300 is arranged on the inner wall or the outer wall of the housing, or a part of the housing constitutes the touch sensor 300.

[0179] In some examples, the touch sensor 300 and the first antenna branch 201 can be insulated from each other (i.e., electrically isolated from each other) or electrically connected to each other. For example, the two can be insulated from each other, in which case they are independent of each other and do not affect each other, and the touch sensor 300 is only used for detecting a touch action. Alternatively, the two can also be electrically connected to each other, in which case the touch sensor 300 can also be reused as part of the antenna branch for communication, so that the antenna design of the present application becomes more flexible.

[0180] Here, the mutual insulation between the touch sensor 300 and the first antenna branch 201 means that the two are arranged to be mutually insulated, and are physically separated by air or insulating material. It does not mean that no induced current will be generated between the two. In other words, in some examples, an induced current can be generated between the touch sensor 300 and the first antenna branch 201, which is not specially limited in the present application.

[0181] In some examples, the processor 400 can be a CPU or any processor, processing unit or processing module capable of controlling the antenna assembly 200 according to the detection signals of the touch screen 110 and the touch sensor 300.

[0182] In some examples, the processor 400 controls the antenna assembly 200 according to the detection signals, which can be switching the antenna branches. Specifically, the processor 400 determines that the first antenna branch 201 being used for wireless communication is held by the user according to the detection signals, and at this time, the processor 400 can switch the antenna branch used for communication of the antenna assembly 200 from the first antenna branch 201 to another antenna branch (e.g. the fifth antenna branch 205 in FIG. 5) not held by the user. For example, the processor 400 can control an antenna switching switch (e.g. a single-pole multi-throw switch) to achieve the switching of the antenna branches, and the operating frequency bands of the antenna branches before and after the switching (e.g. the first antenna branch 201 and the fifth antenna branch 205) can be the same.

[0183] For example, in combination with FIG. 5, the switching of the antenna assembly 200 can include that the antenna branch connected to the first radio frequency front end 210 is switched, i.e. the first radio frequency front end 210 is no longer electrically connected to the first antenna branch 201, but is electrically connected to another antenna branch. It can also include that the first radio frequency front end 210 originally electrically connected to the first feeding point 211 of the first antenna branch 201 is no longer electrically connected to the first feeding point 211, i.e. the electrical connection between the first radio frequency front end 210 and the first feeding point 211 is disconnected (e.g. by changing the state of the switch), and the first antenna branch 201 is no longer in operation.

[0184] In some examples, the processor 400 controls the antenna assembly 200 according to the detection signals, which can be intelligent tuning of the antenna assembly 200. Specifically, the processor 400 determines that the first antenna branch 201 being used for wireless communication is held by the user according to the detection signals, and can even determine parameters such as the position and / or area where the first antenna branch 201 is held by the user. At this time, the processor 400 can control the tuning elements (e.g. by changing the state of the corresponding switch) to achieve intelligent tuning of the antenna assembly 200, so that the resonant frequency of the first antenna branch 201 can match the required communication frequency (i.e. operating frequency), so that the first antenna branch 201 has good transmission efficiency.

[0185] For example, the intelligent tuning of the antenna assembly 200 can include controlling a tuning circuit of the antenna assembly 200. The tuning circuit is electrically connected to the first antenna branch 201, and can include components such as switches, capacitors, or inductors. The processor 400 can change the state of the switches (for example, switch among multiple states of the switches) to connect the first antenna branch 201 to different components such as capacitors or inductors, thereby achieving intelligent tuning of the antenna assembly 200.

[0186] In some examples, the processor 400 controls the antenna assembly 200 according to the detection signal, which can be to control the antenna assembly 200 to reduce the power of the first antenna branch 201. Specifically, the touch sensor 300 can be equivalent to a specific absorption rate (SAR) sensor, and the processor 400 can determine, according to the detection signal, that the user's head / body is close to the electronic device 100 (for example, holding the electronic device 100 close to the ear to make a call), and thus can adjust the power of the first antenna branch 201 of the antenna assembly 200 to achieve the function of the SAR sensor.

[0187] In some examples, the processor 400 controls the antenna assembly 200 according to the detection signal, which can also be to adjust the transmission power of the first antenna branch 201, or to add a new antenna branch to communicate in a corresponding frequency band, or to control the antenna assembly 200 in other aspects, which are not specifically limited in the present application.

[0188] In some examples, when the first antenna branch 201 is detected to enter the working state (turned on), the processor 400 controls the touch screen 110 and the touch sensor 300 to enter the working state to obtain the detection signal.

[0189] In some examples, the touch sensor 300 is arranged adjacent to the first antenna branch 201, thereby facilitating high-precision touch detection.

[0190] In some examples, the first antenna branch 201 includes at least a part (for example, at least one section) of the conductive frame 120a. That is, at least part of the conductive frame 120a can also be reused as the first antenna branch 201, thereby being able to reduce the space occupied by the antenna assembly 200, ensure good radiation performance of the antenna branch, and facilitate reduction of the difficulty of antenna design.

[0191] For example, the first antenna branch 201 can include at least one section of the conductive frame 120a. The section herein can be a section of the conductive frame 120a between two slots 230 (as shown in FIG. 5), a section between two grounding points, or a section between a slot and a grounding point. The section can be provided with a feeding point to serve as a main feeding antenna, or can be provided without a feeding point to serve as a parasitic antenna. The application does not make special limitations in this regard.

[0192] In some examples, as shown in FIG. 8, one section of the conductive frame 120a constitutes the first antenna branch 201, and the touch sensor 300 is a touch panel located inside and adjacent to the first antenna branch 201, with the sensing surface of the touch panel facing outward (i.e., toward the first antenna branch 201) to detect the touch action of a user.

[0193] In some examples, as shown in FIG. 8, the touch sensor 300 is disposed adjacent to the first feeding point 211 of the first antenna branch 201. For example, the touch sensor 300 can be a touch panel located on the inner side of the first antenna branch 201, with the sensing surface of the touch panel facing outward (i.e., toward the first feeding point 211) and disposed adjacent to the first feeding point 211 of the first antenna branch 201.

[0194] When a feeding point of an antenna branch is held by a user's hand, it will have a great impact on the communication performance of the antenna branch. The touch sensor 300 in the embodiment of the application is disposed adjacent to the first feeding point 211 of the first antenna branch 201, which can be used to detect whether the first feeding point 211 is held by a user's hand, and helps to achieve high-accuracy and high-precision control of the antenna assembly 200, further reduces the impact of a user's hand on the communication performance, and improves the user's experience.

[0195] In some examples, as shown in FIG. 8, the touch sensor 300 is disposed adjacent to the first feeding point 211, which can be that the orthographic projection of the touch sensor 300 on the conductive frame 120a covers the first feeding point 211. Alternatively, the orthographic projection of the touch sensor 300 on the conductive frame 120a can not coincide with (be staggered from) the first feeding point 211, and the distance between the proximal edge of the orthographic projection and the first feeding point 211 is less than a certain threshold value, which can be 0.1 mm to 15 mm, for example, 0.5 mm, 1 mm, 2 mm, 3 mm, 5 mm, 8 mm, 10 mm, or 12 mm, etc.

[0196] In some examples, as shown in FIG. 8, the touch sensor 300 can be a touchpad, which can be a strip structure extending along the conductive frame 120a, with the sensing surface of the touchpad facing outward of the device, for example, facing the conductive frame 120a, or can also face the back cover 130. The length of the strip structure can be greater than or equal to 0.2 cm, for example, 0.35 cm, 0.5 cm, 0.8 cm, 1.0 cm, 1.2 cm, 1.5 cm, 1.8 cm, or 2 cm, etc., so as to be able to better identify the touch position.

[0197] In some examples, the touch sensor 300 is disposed adjacent to the strongest current position of the first antenna branch 201, where the strongest (maximum) current position is generally determined by the antenna design. For example, the touch sensor 300 can be a touchpad, which is located inside the first antenna branch 201, with the sensing surface of the touchpad facing outward of the device and adjacent to the strongest current position of the first antenna branch 201.

[0198] When the strongest current position of an antenna branch is held by a user's hand, it will have a great impact on the communication performance of the antenna branch. The touch sensor 300 in the embodiments of the present application is disposed adjacent to the strongest current position of the first antenna branch 201, which can be used to detect whether the strongest current position is held by the user's hand, and helps to achieve high-accuracy and high-precision control of the antenna assembly 200, further reducing the impact of the user's hand on the communication performance, and improving the user's experience.

[0199] In some examples, the touch sensor 300 is disposed adjacent to the strongest current position, which can be that the orthographic projection of the touch sensor 300 on the conductive frame 120a covers the strongest current position. Alternatively, the orthographic projection of the touch sensor 300 on the conductive frame 120a can not coincide (overlap) with the strongest current position, and the distance between the proximal edge of the orthographic projection and the strongest current position is less than a certain threshold, which can be 0.1 mm to 15 mm, for example, 0.5 mm, 1 mm, 2 mm, 3 mm, 5 mm, 8 mm, 10 mm, or 12 mm, etc.

[0200] In some examples, the touch sensor 300 is disposed adjacent to the open end of the first antenna branch 201. The open end is the end of the first antenna branch 201 that plays a major role in radiation and is not grounded. For example, the touch sensor 300 can be a touchpad, which is located inside the first antenna branch 201, with the sensing surface of the touchpad facing outward of the device and disposed adjacent to the open end of the first antenna branch 201.

[0201] As a part of the antenna branch playing a major role in radiation, when the open end is held by the user's hand, it will have a great impact on the communication performance of the antenna branch. The touch sensor 300 in the embodiment of the application is arranged adjacent to the open end of the first antenna branch 201, and can be used to determine whether the open end of the first antenna branch 201 is held by the user's hand, thereby helping to achieve high-accuracy and high-precision control of the antenna assembly 200, further reducing the impact of the user's hand on the communication performance, and improving the user's experience.

[0202] In some examples, the touch sensor 300 is arranged adjacent to the open end of the first antenna branch 201, and the orthographic projection of the touch sensor 300 on the conductive frame 120a can coincide with the open end. Alternatively, the orthographic projection of the touch sensor 300 on the conductive frame 120a can not coincide with the open end (mutually staggered), and the distance between the proximal edge of the orthographic projection and the open end is less than a certain threshold value, which can be 0.1 mm to 15 mm, for example, 0.5 mm, 1 mm, 2 mm, 3 mm, 5 mm, 8 mm, 10 mm, or 12 mm, etc.

[0203] FIG. 9 is a structural schematic diagram of another example of the circuit structure of the electronic device 100 according to the embodiment of the application. As shown in part (a) of FIG. 9, two adjacent segments of the conductive frame 120a constitute the first antenna branch 201 and the second antenna branch 202, respectively, and the open end 201 of the first antenna branch 201 and the second antenna branch 202 have a gap 230 therebetween. At this time, the gap 230 is shared by the first antenna branch 201 and the second antenna branch 202. The touch sensor 300 is arranged adjacent to the open end 201 and located inside the open end 201, and the touch sensor 300 can be a touch panel with the sensing surface facing the outside of the device, for example.

[0204] As shown in part (b) of FIG. 9, one segment of the conductive frame 120a constitutes the first antenna branch 201, and the open end 201 of the first antenna branch 201 and the lower segment have a gap 230 therebetween, at this time, the lower segment is grounded and not used as an antenna branch, and the gap 230 is exclusively used by the first antenna branch 201. The touch sensor 300 is arranged adjacent to the open end 201 and located inside the open end 201, and the touch sensor 300 can be a touch panel with the sensing surface facing the outside of the device, for example.

[0205] As shown in part (c) of FIG. 9, the first antenna branch 201 is disposed on the inner side of the insulating frame 120b, and no other antenna branch or other conductor exists in the vicinity of the open end 201 of the first antenna branch 201, so that the edge of the open end 201 can not have a significant gap or slit. The touch sensor 300 is disposed adjacent to and on the inner side of the open end 201, and can be, for example, a touchpad with a sensing surface facing outward of the device.

[0206] FIG. 10 is a structural schematic diagram of another example of the circuit structure of the electronic device 100 according to an embodiment of the present application. In the example shown in FIG. 10, the two adjacent segments of the conductive frame 120a constitute the first antenna branch 201 and the second antenna branch 202 respectively, and the touch sensor 300 is a touchpad disposed inside the conductive frame 120a and adjacent to the gap 230 between the first antenna branch 201 and the second antenna branch 202, with a sensing surface facing outward (i.e., facing the gap 230) to detect touch actions of a user.

[0207] When the gap between adjacent antenna branches is held by a user's hand, it will have a great impact on the communication performance of the antenna branches. The touch sensor 300 in the present embodiment is disposed adjacent to the gap 230 between the first antenna branch 201 and the second antenna branch 202, and can be used to detect whether the gap 230 is held by a user's hand, which helps to achieve high-accuracy and high-precision control of the antenna assembly 200, further reduces the impact of a user's hand on the communication performance, and improves the user experience.

[0208] In some examples, as shown in FIG. 10, the touch sensor 300 is disposed adjacent to the gap 230, and the orthographic projection of the touch sensor 300 on the conductive frame 120a can cover the gap 230. Alternatively, the orthographic projection of the touch sensor 300 on the conductive frame 120a can not coincide with (be offset from) the gap 230, and the distance between the proximal edge of the orthographic projection and the gap 230 can be less than a certain threshold, which can be, for example, 0.1 mm to 15 mm, such as 0.5 mm, 1 mm, 2 mm, 3 mm, 5 mm, 8 mm, 10 mm, or 12 mm, etc.

[0209] FIG. 11 is a structural schematic diagram of various ways of disposing the touch sensor 300 according to an embodiment of the present application. The touch sensor 300 can be disposed in various ways adjacent to the gap 230, as shown in part (a) of FIG. 11, the touch sensor 300 can also be disposed on the outer side of the gap 230, for example, on the outer wall of the conductive frame 120a, in which case the orthographic projection of the touch sensor 300 on the conductive frame 120a also covers the gap 230, i.e., the touch sensor 300 covers the gap 230 from the outside.

[0210] As another way of being arranged adjacent to, as shown in part (b) of FIG. 11, the touch sensor 300 can also be arranged on the upper side of the gap 230, for example, on the first antenna branch 201, in which case the touch sensor 300 and the first antenna branch 201 can be electrically connected to each other or insulated from each other. For example, the two can be electrically connected to each other, the touch sensor 300 is used for communication as part of the first antenna branch 201, or the touch sensor 300 can also constitute a complete antenna branch, and the touch sensor 300 is the first antenna branch 201.

[0211] As another way of being arranged adjacent to, as shown in part (c) of FIG. 11, the touch sensor 300 can also be arranged on the lower side of the gap 230, for example, on the second antenna branch 202, in which case the touch sensor 300 and the first antenna branch 201 can be electrically connected to each other or insulated from each other. For example, the two can be electrically connected to each other, the touch sensor 300 is used for communication as part of the second antenna branch 202, or the touch sensor 300 can also constitute a complete antenna branch, and the touch sensor 300 is the second antenna branch 202.

[0212] As another way of being arranged adjacent to, as shown in part (d) of FIG. 11, the touch sensor 300 can also be arranged in the gap 230 and electrically insulated from the first antenna branch 201 and the second antenna branch 202. In summary, the above-mentioned various ways of being arranged adjacent to show that the relative position of the touch sensor 300 and the gap 230 is not specially limited in the present application.

[0213] In some examples, the touch sensor 300 can be a touchpad, and the sensing surface of the touchpad is arranged towards the outside of the device to facilitate detection of touch actions of the user. For example, the sensing surface is parallel or approximately parallel to the outer wall surface of the frame 120, thereby being able to detect touch actions on the frame 120; or the sensing surface is parallel or approximately parallel to the outer wall surface of the back cover 130, thereby being able to detect touch actions on the back cover 130.

[0214] For example, as shown in FIG. 10, the touch sensor 300 is a touchpad, which is located inside the device and adjacent to the gap 230. The "sensing surface of the touchpad faces the outside of the device" can be that the sensing surface of the touchpad faces the conductive frame 120a or the gap 230, or that the sensing surface of the touchpad faces the back cover 130. Regardless of the above arrangement, the touchpad can effectively detect the touch action near the gap 230 and effectively detect whether the gap 230 is held by the user. That is, the specific orientation of the sensing surface of the touchpad is not particularly limited in the present application, and any orientation that can effectively detect the touch action should be included in the protection scope of the present application.

[0215] In some examples, the touch sensor 300 is arranged adjacent to the first feed point 211 of the first antenna branch 201, or adjacent to the open end of the first antenna branch 201, or adjacent to the gap 230, or adjacent to the position of the strongest current of the first antenna branch 201, where the "adjacent" can be that the distance (e.g. the minimum distance) between the touch sensor 300 and the corresponding position is greater than or equal to 0 and less than or equal to 5 millimeters (mm). For example, the distance between them is less than or equal to 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, or 4 mm, etc., for example, the distance between them can be 0.01 mm, 0.02 mm, 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.5 mm, 0.8 mm, 1 mm, 1.5 mm, 2 mm, 3 mm, or 4 mm, etc., but not limited thereto.

[0216] FIG. 12 is a structural schematic diagram of another example of the circuit structure of the electronic device 100 provided by the embodiments of the present application. In the embodiment shown in FIG. 12, the antenna assembly 200 includes a plurality of antenna branches, for example, the first antenna branch 201 to the eighth antenna branch 208, and the touch sensor 300 has a plurality of (for example, including 9 in FIG. 12). The touch screen 110 and the plurality of touch sensors 300 are used to jointly detect the touch action of the user acting on the electronic device 100 and located near the plurality of antenna branches, and generate a detection signal, and the processor 400 controls the antenna assembly 200 according to the detection signal.

[0217] The present application can detect the touch action near any antenna branch through the plurality of touch sensors 300 corresponding to the plurality of antenna branches, and in combination with the detection signal of the touch screen 110, so that the processor 400 can accurately identify which antenna branch or antenna branches are held by the user, and thereby achieve high-accuracy and high-precision control of the antenna assembly 200, further reduce the influence of the user's hand holding on the communication performance, and improve the user's experience.

[0218] In some examples, the number of touch sensors 300 is equal to the number of antenna branches of the antenna assembly 200, and each touch sensor 300 is arranged corresponding to one antenna branch, and each touch sensor 300 is used to detect touch action near the corresponding antenna branch.

[0219] In some examples, the number of touch sensors 300 is not equal to the number of antenna branches of the antenna assembly 200, for example, the number of touch sensors 300 is less than the number of antenna branches of the antenna assembly 200, or the number of touch sensors 300 is greater than the number of antenna branches of the antenna assembly 200, which is not specially limited in the present application.

[0220] In some examples, for the antenna branches that are not easy to be held by the user, the corresponding touch sensor 300 can not be arranged.

[0221] In some examples, for some pairs of antenna branches that have greater impact on communication performance, multiple touch sensors 300 can be arranged, for example, two touch sensors 300 can be arranged for the first antenna branch 201 in FIG. 12, one of the touch sensors 300 is arranged adjacent to the first feed point 211 of the first antenna branch 201, and the other touch sensor 300 is arranged adjacent to the gap 230 between the first antenna branch 201 and the second antenna branch 202.

[0222] FIG. 13 is a schematic diagram of the distribution of the touch sensor 300 according to an embodiment of the present application. As shown in FIG. 13, in the embodiment of the present application, part of the antenna branches of the antenna assembly 200 can be located on the conductive frame 120a, that is, the segments of the conductive frame 120a constitute the part of the antenna branches, and part of the antenna branches (for example, the remaining antenna branches) of the antenna assembly 200 can be located on the inner wall of the insulating back cover 130a.

[0223] The touch sensor 300 can be located inside the shell, and the sensing surface faces the outside of the device. Multiple touch sensors 300 are arranged for multiple antenna branches, and the multiple touch sensors 300 are sparsely distributed at different positions of the shell. Part of the touch sensors 300 are arranged adjacent to the conductive frame 120a, for example, the part of the touch sensors 300 are arranged on the inner wall of the conductive frame 120a. Another part of the touch sensors 300 are arranged adjacent to the insulating back cover 130a, for example, the part of the touch sensors 300 are arranged on the inner wall of the insulating back cover 130a.

[0224] The plurality of touch sensors 300 are electrically connected with the processor 400, and the processor 400 controls the antenna assembly 200 according to the detection signals of the plurality of touch sensors 300 and the touch screen 110, so as to improve the accuracy and precision of the control of the antenna assembly 200, for example, to facilitate precise and timely antenna branch switching and / or high-precision intelligent tuning.

[0225] In some examples, the processor 400 can also identify a holding gesture of the user on the electronic device 100 according to the detection signals of the plurality of touch sensors 300 and the touch screen 110, for example, a single-hand holding, a two-hand holding, a left-hand holding, a right-hand holding, and whether the electronic device 100 is held horizontally or vertically, and the like, and then control the antenna assembly 200 in terms of antenna branch switching and / or intelligent tuning according to the identified holding gesture, but not limited thereto. For example, the content displayed on the touch screen 110 can also be adjusted in position according to the identified holding gesture, so as to facilitate the user to perform a touch operation and improve the user's experience.

[0226] For example, the processor 400 first identifies a holding gesture of the user on the electronic device 100 according to the detection signals, and then controls the antenna assembly 200 according to the identified holding gesture. In combination with the holding gesture, information such as which side of the electronic device 100 is held more strongly by the user and which side has a higher coverage rate can be determined, so that the antenna assembly 200 can be controlled more accurately according to the holding gesture (i.e., in combination with the above information), which is beneficial to further ensure that the efficiency of communication is not affected by hand holding. In addition, the processor 400 can also adjust the position of the content displayed on the touch screen 110 according to the identified holding gesture, so as to facilitate the user to perform better touch interaction. That is, the specific use of the holding gesture identified by the processor 400 is not specially limited in the present application.

[0227] In some examples, the processor 400 is further configured to obtain information associated with the holding gesture of the user on the electronic device 100 according to the detection signals. The processor 400 can further control the electronic device 100 according to the associated information, for example, control the antenna assembly 200 or control the content displayed on the touch screen 110, so as to improve the user's experience.

[0228] For example, the associated information can be information of a user interface (UI) associated with the holding gesture, so that the processor 400 can adjust the UI displayed on the touch screen 110 according to the information, for example, adjust the position of the control, so as to facilitate the user to perform better touch interaction.

[0229] In some examples, at least one of the plurality of touch sensors 300 can not be arranged for the antenna branch, for example, the at least one touch sensor 300 can be arranged at a region of the electronic device 100 that is frequently contacted by the user's hand when the user uses the electronic device 100, to facilitate the processor 100 to accurately recognize the holding gesture.

[0230] In some examples, the processor 400 recognizes the holding position of the user, which antenna branch is held by the user, or recognizes the holding gesture of the user according to the detection signals of the plurality of touch sensors 300 and the touch screen 110, and in combination with an AI classification recognition algorithm. The AI classification recognition algorithm may, for example, be an algorithm in machine learning such as a decision tree, a support vector machine (SVM), a K-nearest neighbor (KNN), or a neural network algorithm such as a deep neural network (DNN), a convolutional neural network (CNN), or a commonly used slightly larger neural network model (such as Res-Net18), but is not limited thereto.

[0231] FIG. 14 is a distribution diagram of the detection region of the touch sensor 300 provided by the embodiments of the present application, and FIG. 15 is a schematic diagram of the holding gesture of the user determined according to the detection signals of the touch sensor 300. As shown in FIGS. 14 and 15, the touch sensor 300 and the touch screen 110 have a plurality of detection regions arranged along a touch plane array, each square in FIG. 14 represents a detection region, and each detection region can detect the touch action of the user and generate a corresponding detection signal. For example, the square with a gray background and containing the number "1" in FIG. 14 indicates that the detection region detects the touch action of the user, and the square with a white background and containing the number "0" in FIG. 14 indicates that the detection region does not detect the touch action of the user.

[0232] The touch sensor 300 performs touch detection with the touch screen 110 and generates a corresponding detection signal, and the processor 400 receives the detection signal from the touch sensor 300 and the touch screen 110, and identifies the holding gesture of the user in combination with a preset AI classification recognition algorithm. As shown in FIG. 15, the identified holding gesture is a double-hand vertical holding gesture, and the holding position is located at the lower part of the electronic device 100. At this time, the processor 400 can control the antenna assembly 200 in terms of antenna branch switching and / or intelligent tuning according to the identified holding gesture, for example, control the antenna assembly 200 to use the antenna branch located above the electronic device 100 and not held by the user to perform wireless communication, thereby avoiding the influence of the user's hand holding on the antenna performance and improving the user's use experience. In addition, the processor 400 can also adjust the position of the content (such as the control) displayed on the touch screen 110 according to the identified holding gesture, so as to facilitate the user to perform touch operation and improve the user's use experience.

[0233] The above merely provides a specific implementation of the present application, but the protection scope of the present application is not limited thereto.
