Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to an electronic device. Background Technology

[0002] As electronic devices support more and more functions, the number of antennas is also increasing. The quality of antenna performance directly affects the communication signal and network quality of electronic devices, playing a crucial role in user experience.

[0003] Currently, electronic devices typically use multiple antennas arranged around the device's frame, separated by insulating gaps. For example, a metal frame can be used as part of the antenna, divided into electrically isolated segments by multiple gaps. Each segment can be reused as an antenna stub for transmitting and receiving radio frequency signals. Furthermore, multiple antennas can be switched between each other to avoid the user's grip.

[0004] In related technologies, the touchscreen on the front of the phone is used to detect the user's grip position on the frame, and then the antenna can be switched or intelligently tuned based on the detection results. However, the touchscreen is mainly used to detect touch actions on the front of the phone, and its ability to detect antenna grip and touch is very limited, resulting in low detection accuracy. These reasons further lead to lower accuracy and precision in controlling the antenna when the phone is held, affecting the antenna's communication performance. Summary of the Invention

[0005] This application provides an electronic device that can improve the accuracy of touch detection, achieve high accuracy and high precision control of antenna components, and minimize the impact of user hand grip on communication performance.

[0006] In a first aspect, an electronic device is provided, comprising: an antenna assembly including a first antenna stub; a touchscreen for detecting a touch action performed by a user on the electronic device and adjacent to the first antenna stub; a touch sensor for detecting the touch action performed by the user on the electronic device and adjacent to the first antenna stub; and a processor for controlling the antenna assembly based on the detections from the touchscreen and the touch sensor.

[0007] The electronic device provided in this application embodiment is additionally equipped with a touch sensor. The touchscreen and the touch sensor are simultaneously used to detect user touch actions near the first antenna stub. Compared to existing technologies that rely solely on the touchscreen to detect user touch actions, this application improves touch detection accuracy, for example, enabling grip position recognition at the 1mm level. Based on this, the processor can simultaneously control the antenna assembly based on the detection signals from both the touchscreen and the touch sensor, thereby improving the accuracy and precision of antenna assembly control. This facilitates precise and timely antenna stub switching and / or high-precision intelligent tuning. Consequently, the electronic device provided in this application minimizes the impact of user hand grip on communication performance, ensuring the antenna assembly always maintains optimal operating conditions and enhancing the user experience.

[0008] Here, the touchscreen and touch sensor detect user touch actions on the electronic device and near the first antenna stub. This can also be understood as detecting user touch actions on the electronic device and located near the first antenna stub. The touch action can be any action that affects the communication performance of the first antenna stub, such as a touch, approach, or grip action (e.g., the aforementioned "death grip" or "feint"), but is not limited to these. The touch action can be an active or unconscious touch action by the user on the electronic device. It can be an action where the user is in contact with the surface of the electronic device (the user is in contact with the surface) or an action where the user is near the surface (the user is not in contact with the surface, such as the aforementioned "hovering touch"). Furthermore, the touch action 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.

[0009] Here, "touch actions near the first antenna stub" refers to touch actions near the first antenna stub that affect communication performance. For example, a touch action near the first antenna stub can be a touch action within a certain range around the first antenna stub, such as a touch action within 5mm, 15mm, 20mm, or 35mm of the distance to the first antenna stub. It is easy to understand that the above touch actions are detected by the touchscreen and touch sensor, therefore, they should have detection capabilities corresponding to the aforementioned distance range.

[0010] In some examples, the touchscreen detects a user's touch action on the electronic device and near the first antenna stub to generate a first detection signal; the touch sensor detects the user's touch action on the electronic device and near the first antenna stub to generate a second detection signal; the processor controls the antenna assembly based on the first and second detection signals. Because the processor can control the antenna assembly simultaneously based on the detection signals from both the touchscreen and the touch sensor, the accuracy and precision of the antenna assembly control can be improved.

[0011] In some examples, a touch action near the first antenna stub can be a touch action within a certain range around the first antenna stub, such as a touch action within 20mm of the perimeter. Furthermore, depending on the sensing accuracy, the touchscreen and / or touch sensor can detect touch actions within, for example, 30mm or 20mm of the perimeter. This application uses a range of 20mm as an example for illustration, and is not intended to limit the sensing accuracy of the touchscreen and / or touch sensor, but rather to describe the usage scenario of this application embodiment to facilitate understanding.

[0012] In some examples, although the touch screen and touch sensor can detect touch actions within a 20mm radius, the "touch action near the first antenna stub" detected by the touch screen and touch sensor can be the action of the user touching or touching the first antenna stub. The processor can control the antenna assembly based on the detection signal of the above action by the touch screen and touch sensor, such as switching the stub.

[0013] In some examples, the touchscreen and touch sensor detect the user's touch action near the first antenna stub. This could be detecting whether the first antenna stub is being held by the user, or detecting the distance (i.e., proximity) between the touch action and the first antenna stub, or detecting whether the user's grip on the first antenna stub is a firm grip or a loose grip, etc.

[0014] In some examples, the touchscreen and touch sensor detect the user's touch action near the first antenna stub. This can be to detect whether the first antenna stub is being held by the user, and if so, to detect parameters such as the user's grip position, grip tightness (pressure), grip length, or grip area.

[0015] In one possible implementation, the electronic device includes a housing, the touchscreen is mounted on the housing, and the first antenna stub is part of the housing, or the first antenna stub is located within the housing. This configuration improves the flexibility of antenna placement and helps reduce the difficulty of antenna design.

[0016] In one possible implementation, the housing includes a conductive frame, and the first antenna stub includes at least a portion (e.g., at least one segment) of the conductive frame. That is, at least a portion of the conductive frame can be reused as the first antenna stub, thereby reducing the space occupied by the antenna assembly, ensuring good radiation performance of the antenna stub, and reducing the difficulty of antenna design.

[0017] For example, the first antenna stub may include at least one segment of a conductive frame. This segment may be a segment of the conductive frame located between two gaps, a segment located between two grounding points, or a segment between a gap and a grounding point. A feed point may be provided on the segment for use as a main feed antenna, or it may not be provided for use as a parasitic antenna; this application does not impose any special limitations on this.

[0018] In one possible implementation, the housing includes an insulating frame, and the first antenna stub is located within the housing and disposed adjacent to the inner wall of the insulating frame.

[0019] By adopting the above configuration, the area occupied by the first antenna stub can be minimized, allowing it to be placed closer to the edge of the electronic device and achieving better radiation performance. Furthermore, since no gaps need to be created in the frame, the integrity of the frame structure can be guaranteed, ensuring sufficient structural strength.

[0020] It should be noted that the first antenna stub being located near the inner wall of the insulating frame can mean that the first antenna stub is fixed to the inner wall of the insulating frame by means of bonding or other processes; or that the first antenna stub is located close to the inner wall of the insulating frame; or that the antenna stub is located close to the insulating frame, but there is a certain small gap between the two (e.g., 0.01 mm to 2 mm). This application does not make any special limitation on this.

[0021] In some examples, the first antenna stub is disposed inside the housing and adjacent to the inner wall of the insulating frame. "Adjacent" here means that the distance (e.g., minimum distance) between the first antenna stub and the insulating frame is greater than or equal to 0 and less than or equal to 5 millimeters (mm). For example, the distance between them can be less than or equal to 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, or 4mm, etc., but is not limited to these values.

[0022] In some examples, the first antenna stub can be an antenna form of flexible printed circuit (FPC), laser direct structuring (LDS), microstrip antenna (MDA), or printing direct structuring (PDS).

[0023] In some examples, the first antenna stub can be positioned between the insulating frame and the battery.

[0024] In one possible implementation, the housing includes an insulating back cover, with the first antenna stub located within the housing and disposed adjacent to the inner wall of the insulating back cover.

[0025] By adopting the above configuration, the area occupied by the first antenna stub can be minimized, allowing it to be placed closer to the edge of the electronic device and achieving better radiation performance. Furthermore, since no gaps need to be created in the frame, the integrity of the frame structure can be guaranteed, ensuring sufficient structural strength.

[0026] It should be noted that the first antenna stub mentioned here being located near the inner wall of the insulating back cover can mean that the antenna stub is fixed to the inner wall of the insulating back cover by means of bonding or other processes; or that the antenna stub is located close to the inner wall of the insulating back cover; or that the antenna stub is located close to the insulating back cover, but there is a certain small gap between the two (e.g., 0.01 mm to 2 mm). This application does not make any special limitation on this.

[0027] In some examples, the first antenna stub is disposed inside the housing and adjacent to the inner wall of the insulating back cover. "Adjacent" here means that the distance (e.g., minimum distance) between the first antenna stub 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 can be less than or equal to 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, or 4mm, etc., but is not limited to these.

[0028] In some examples, the first antenna stub may also be embedded in the insulating back cover, or located on the outside of the insulating back cover, such as in the camera trim piece.

[0029] In some examples, the first antenna stub can be an FPC antenna, an LDS antenna, a microstrip antenna (MDA) antenna, or a PDS antenna, etc.

[0030] In some examples, the first antenna stub can be positioned between the insulating back cover and the battery.

[0031] In some examples, the interior of the insulating back cover may have a groove in which the first antenna stub may be disposed.

[0032] In one possible implementation, the touch sensor is positioned adjacent to a first feed point of the first antenna stub.

[0033] When the feed point of an antenna stub is held by a user, it will have a significant impact on the communication performance of that antenna stub. The touch sensor of this application is located near the first feed point of the first antenna stub and can be used to detect whether the first feed point is held by a user. This helps to achieve high accuracy and high precision control of the antenna assembly, further reduces the impact of the user's grip on the communication performance, and improves the user experience.

[0034] In some examples, the touch sensor is positioned adjacent to the first feed point, which may be because the orthographic projection of the touch sensor on the conductive frame covers the first feed point. Alternatively, the orthographic projection of the touch sensor on the conductive frame may not coincide with the first feed point (they may be offset from each other), and the distance between the near edge of the orthographic projection and the first feed point is less than a certain threshold, which may 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.

[0035] In some examples, the touch sensor can be a touchpad, which can be a strip-shaped structure extending along a conductive frame, with the sensing surface of the touchpad facing outwards from the device, such as towards the conductive frame, or possibly towards 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, thereby enabling better touch position recognition.

[0036] In one possible implementation, the touch sensor is positioned adjacent to the open end of the first antenna stub.

[0037] As the main radiating part of the antenna stub, the communication performance of the antenna stub will be greatly affected when the open end is held by the user. The touch sensor of this application is located near the open end of the first antenna stub and can be used to determine whether the open end of the first antenna stub is held by the user. This helps to achieve high accuracy and high precision control of the antenna assembly, further reduces the impact of the user's grip on the communication performance, and improves the user experience.

[0038] In one possible implementation, the antenna assembly further includes a second antenna stub with a gap between the second antenna stub and the open end of the first antenna stub, and the touch sensor is disposed adjacent to the gap.

[0039] When the gap between adjacent antenna stubs is held by a user, it will have a significant impact on the communication performance of the antenna stubs. The touch sensor in this application is set to be adjacent to the gap between the first antenna stub and the second antenna stub, which can be used to detect whether the gap is held by a user. This helps to achieve high accuracy and high precision control of the antenna components, further reduces the impact of user grip on communication performance, and improves the user experience.

[0040] In some examples, the gap adjacent to the touch sensor is configured such 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 may not coincide with the gap (they may be offset from each other), and the distance between the proximal edge of the orthographic projection and the gap may be less than a certain threshold, such as 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.

[0041] In one possible implementation, the touch sensor is positioned near the location of the strongest current in the first antenna stub.

[0042] When the strongest current position of an antenna stub is held by a user, it will have a significant impact on the communication performance of that antenna stub. The touch sensor in this embodiment is set near the strongest current position of the first antenna stub, which can be used to detect whether the strongest current position is held by a user. This helps to achieve high accuracy and high precision control of the antenna components, further reduces the impact of the user's grip on communication performance, and improves the user experience.

[0043] In one possible implementation, the touch sensor is either insulated from or electrically connected to the first antenna stub.

[0044] For example, the two devices can be insulated from each other, in which case they are independent and do not affect each other, and the touch sensor is only used to detect touch actions. Alternatively, the two devices can be electrically connected to each other, in which case the touch sensor can also be reused as part of the antenna stub for communication, thus making the antenna design of this application more flexible.

[0045] Here, the insulation between the touch sensor and the first antenna stub means that they are physically separated and insulated from each other, with air or insulating material between them. It does not mean that no induced current will be generated between them; in other words, in some examples, an induced current can be generated between the touch sensor and the first antenna stub, which this application does not specifically limit.

[0046] In one possible implementation, the processor controls the antenna assembly based on the detection signal, including any one of the following controls: controlling the antenna assembly to switch antenna stubs; controlling the tuning circuit of the antenna assembly; controlling the antenna assembly to adjust the power of the first antenna stub.

[0047] In one possible implementation, the antenna assembly includes multiple antenna stubs, the touch sensor has multiple stubs, the touchscreen and the multiple touch sensors are used to jointly detect touch actions by the user on the electronic device and near the multiple antenna stubs, and generate a detection signal, and the processor controls the antenna assembly based on the detection signal.

[0048] This application sets up multiple touch sensors corresponding to multiple antenna stubs, which can detect touch actions near any antenna stub. Combined with the detection signal from the touch screen, the processor can accurately identify which antenna stub(s) are being held by the user, and thereby achieve high-accuracy and high-precision control of the antenna components. This can further reduce the impact of the user's grip on communication performance and improve the user experience.

[0049] In some examples, the number of touch sensors is equal to the number of antenna stubs in the antenna assembly, and the touch sensors are configured in a one-to-one correspondence with the antenna stubs, with each touch sensor used to detect touch actions near the corresponding antenna stub.

[0050] In some examples, the number of touch sensors is not equal to the number of antenna stubs of the antenna assembly. For example, the number of touch sensors may be less than the number of antenna stubs of the antenna assembly, or the number of touch sensors may be greater than the number of antenna stubs of the antenna assembly. This application does not impose any particular limitation on this.

[0051] In some examples, touch sensors may not be required for antenna stubs that are not easily held by the user.

[0052] In some examples, multiple touch sensors can be set for a pair of antenna stubs that have a significant impact on communication performance. For example, two touch sensors can be set for the first antenna stub, with one touch sensor set near the first feed point of the first antenna stub and the other touch sensor set near the gap between the first antenna stub and the second antenna stub.

[0053] In one possible implementation, the processor is further configured to acquire information associated with a user's grip gesture on the electronic device based on the detection signal. The processor can then further control the electronic device based on this associated information, such as controlling antenna components or controlling content displayed on the touchscreen, thereby enhancing the user experience.

[0054] For example, the associated information could be information about the user interface (UI) associated with the grip gesture, so that the processor can adjust the UI displayed on the touchscreen based on this information, such as adjusting the position of controls, to facilitate better touch interaction for the user.

[0055] In one possible implementation, the touch sensor is a touchpad, such as a capacitive touchpad or a resistive touchpad.

[0056] The touchpad consists of a large number of highly integrated touch detection units, each of which corresponds to a detection area. This allows the touchpad to detect not only whether the first antenna stub is touched by the user, but also the user's touch position and touch area. In other words, it detects parameters such as the position, length, or area of ​​the first antenna stub held by the user's hand. This enables the processor to achieve high-accuracy and high-precision control of the antenna components based on the detection signals, further reducing the impact of the user's hand grip on communication performance.

[0057] In some examples, the touch sensor can be located inside or outside the housing of the electronic device. For example, the touch sensor may be located on the inner or outer wall of the housing, or a portion of the housing may constitute the touch sensor.

[0058] In one possible implementation, the touchpad includes a plurality of touch detection units, the density of which 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.

[0059] In one possible implementation, the touch sensor is a touchpad with the sensing surface facing the outside of the electronic device to facilitate the detection of the user's touch actions.

[0060] For example, the sensing surface faces the outside of the device and is parallel or nearly parallel to the outer wall of the frame, thus enabling the detection of touch actions on the frame; or, the sensing surface faces the outside of the device and is parallel or nearly parallel to the outer wall of the back cover, thus enabling the detection of touch actions on the back cover.

[0061] In one possible implementation, the touch sensor is a touchpad, a fingerprint sensor, a pressure sensor, a light sensor, a proximity sensor, a distance sensor, or an electromagnetic wave energy absorption ratio sensor. Attached Figure Description

[0083] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0084] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0085] In the description of this application, it should be understood that the terms "upper", "lower", "side", "front", "rear", etc., indicate the orientation or positional relationship based on the installation orientation or positional relationship, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0086] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "a plurality of" means two or more.

[0087] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0088] Electronic devices with metal frames (such as mobile phones) are favored by users for their superior appearance and have become widely popular. The quality of the antenna directly affects the communication signal and network quality of electronic devices, playing a crucial role in the user experience.

[0089] Currently, the metal frame is typically integrated into the antenna. Multiple slots divide the metal frame into electrically isolated segments, each of which can be reused as an antenna stub (radiator) for transmitting and receiving radio frequency signals. These segments can be switched between each other to avoid interference with the user's grip. For example, if a user is holding a phone while it's communicating via the lower segment, the antenna performance may be severely degraded, leading to a "death grip." In this case, the user can switch to the upper segment of the phone, avoiding the impact of the user's grip and ensuring optimal antenna performance.

[0090] In related technologies, the user's grip position on the frame is detected by the touchscreen on the front of the mobile phone. Based on the detection results, the antenna can be switched or intelligently tuned to ensure communication quality.

[0091] Figure 1 This is a diagram illustrating an application scenario where the user's grip position is detected via a touchscreen. For example... Figure 1 As shown, the metal frame of the mobile phone is divided into multiple electrically isolated segments. These segments, including the first segment 10 and the second segment 20, can be multiplexed as antenna stubs for communication. When the mobile phone is wirelessly communicating via the lower first segment 10, the user's grip position can be detected via the touchscreen 30 on the front of the phone. The touchscreen 30 has multiple detection areas arranged in an array along the touch plane (i.e., the XY plane). Figure 1 Each square in the diagram represents a detection area, and each detection area can detect the user's touch actions and generate corresponding detection results. For example, Figure 1 A gray square containing the number "1" indicates that the detection area has detected a user's touch action. Figure 1 A white square containing the number "0" indicates that no user touch was detected in that detection area.

[0092] Subsequently, the phone's internal processor, based on the detection results from the touchscreen 30 and combined with preset algorithms (such as artificial intelligence (AI) classification and recognition algorithms), identifies the user's grip position and determines that the first segment 10 is being held by the user. At this point, the processor can switch segments, controlling the antenna to use the second segment 20 located at the top of the phone and not being held by the user for wireless communication. This avoids the impact of the user's grip on antenna performance and improves the user experience.

[0093] However, the touchscreen 30 is primarily used to detect touch actions on the front of the phone, and its detection capability for the phone's frame is very limited, resulting in low detection accuracy; for example, it cannot achieve a detection accuracy at the 1mm level. These factors further lead to lower accuracy and precision in controlling the antenna when the phone is held in hand, affecting the antenna's communication performance.

[0094] To address the aforementioned issues, this application provides an electronic device additionally equipped with a touch sensor. This device can simultaneously detect user touch actions near antenna stubs (such as the aforementioned first segment 10 or second segment 20) via both a touchscreen and the touch sensor. This improves touch detection accuracy, enabling, for example, grip position recognition down to the millimeter level. Furthermore, the electronic device can control the antenna assembly based on the detection signals from both the touchscreen and the touch sensor, enhancing the accuracy and precision of antenna assembly control. This facilitates precise and timely antenna stub switching and / or high-precision intelligent tuning. Ultimately, this minimizes the impact of user hand grip on communication performance, ensuring the antenna assembly always operates at its best, thus improving the user experience.

[0095] The electronic devices provided in this application can be, for example, mobile phones, tablets, e-readers, laptops, in-vehicle devices, wearable devices (such as watches, bracelets, or glasses), personal digital assistants (PDAs), point-of-sale (POS) terminals, smart speakers, augmented reality (AR) devices, virtual reality (VR) devices, mixed reality (MR) devices, industrial equipment, video surveillance equipment, and any other electronic product with wireless communication capabilities. Mobile phones can be, for example, conventional candybar phones or foldable phones, such as phones that fold vertically, fold horizontally inward, or fold horizontally outward. This application uses a mobile phone as an example for illustration.

Figure 2 Part (b) is a rear view of electronic device 100. Figure 3 This is a cross-sectional view of the electronic device 100 provided in the embodiments of this application.

[0097] like Figure 2 and Figure 3As shown, the electronic device 100 provided in this application embodiment includes a touch screen 110, a frame 120 and a back cover 130. The frame 120 and the back cover 130 constitute the housing of the electronic device 100, and the touch screen 110 is fixedly mounted on the housing.

[0098] The touchscreen 110 serves as the front panel of the electronic device 100, forming a mounting cavity with the housing for accommodating components such as circuit boards and batteries. The touchscreen 110 provides human-computer interaction between the user and the electronic device 100, such as displaying images, videos, or receiving user input (e.g., receiving touch commands). Specifically, the touchscreen 110 may include a touch panel (TP) and a display screen.

[0099] The touchpad can collect touch events from the user on or near the electronic device 100 (such as user operations on or near the touchpad using a finger, stylus, or any suitable object), and send the collected touch information (touch data) to other devices (such as a processor). In other words, the touchpad in this embodiment can collect touch events performed by the user on the touchpad, such as when the user's finger contacts the touchscreen. Furthermore, the touchpad can also collect touch events near the touchpad. In this case, the user's finger does not need to touch the screen to complete touch operations; for example, maintaining a distance of approximately 15 millimeters between the finger and the screen allows for mouse-like operations on the electronic device.

[0100] Here, a user's touch event near the touchpad can be called hover touch; hover touch means that the user does not need to directly touch the touchpad to select, move, or drag a target (such as an icon), but only needs to be near the device to perform the desired function. Furthermore, touchpads can be implemented using various types, including resistive, capacitive, infrared, and surface acoustic wave.

[0101] The display screen can be used to display information input by the user or information provided to the user. A touchpad can be placed over the display screen. When the touchpad detects a touch event on or near it, it transmits the information to the processor to determine the type of touch event. The processor can then provide corresponding visual output on the display screen based on the type of touch event.

[0102] In some examples, the touchpad and display screen are implemented as two separate components to achieve the input and output functions of the electronic device 100. In other examples, the touchpad and display screen can be integrated to achieve the input and output functions of the electronic device 100. It is understood that the display screen is made of multiple layers of stacked materials, which will not be described in detail in the embodiments of this application.

[0103] In some examples, the display screen may be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a minimized display, a microLED, a micro-OLED, a quantum dot light-emitting diode (QLED) display, etc., but is not limited to these.

[0104] In some examples, the touchscreen 110 can be a multi-touch screen.

[0105] The bezel 120 surrounds the touchscreen 110 to help secure it. In this embodiment, the touchscreen 110 has a rectangular structure, and the bezel 120 includes four connected sides that together form a rectangular hollow structure. The touchscreen 110 is mounted on one end of this hollow structure, and the back cover 130 is mounted on the other end. In some examples, the bezel 120 has chamfered edges for a more aesthetically pleasing appearance. The bezel 120 can be a metal bezel, such as made of aluminum alloy, magnesium alloy, or stainless steel. Alternatively, the bezel 120 can be a non-metallic bezel (i.e., an insulating bezel), such as made of plastic, resin, glass, or ceramic.

[0106] The back cover 130, also known as the back cover, is a structure on the electronic device 100 that is opposite to the touch screen 110 and connected to the frame 120. It encloses the components of the electronic device 100 inside the device and also provides protection against dust, impacts, and scratches. The back cover 130 can be made of metal (i.e., a metal back cover) or non-conductive materials (i.e., a non-metal back cover), such as glass, plastic, or ceramic. Furthermore, the back cover 130 can also be an enamel back cover, which is an enamel material formed by covering a metal substrate with a ceramic enamel layer. This application embodiment does not limit the material of the back cover 130.

[0107] In some examples, when the material in which the back cover 130 is formed includes conductive materials such as metal, for example, when the back cover 130 is a metal back cover or an enamel back cover, the back cover 130 can be used as a reference ground for electronic devices or radio frequency devices within an electronic device.

[0108] like Figure 3 As shown, the electronic device 100 provided in this embodiment also includes a middle plate 150. The middle plate 150 is a support frame located inside the electronic device 100. The middle plate 150 can be made of metal and can be used as the ground terminal (GND) of the electronic device 100. The touch screen 110 and the back cover 130 are disposed on both sides of the middle plate 150. The middle plate 150 may be provided with one or more positioning pillars, positioning holes, or other positioning structures for fixing the components of the electronic device 100 installed in the internal cavity of the whole device. In addition, one or more through holes may be provided on the middle plate 150 to facilitate wiring design.

[0109] A frame 120 surrounds the periphery of the middle plate 150, and the frame 120 and the middle plate 150 are fixedly connected to form the middle frame structure of the electronic device 100. The middle plate 150 and the frame 120 can be a separate structure or an integral structure, which is not limited in this embodiment. When the middle plate 150 and the frame 120 are separate structures, the middle plate 150 and the frame 120 are two different components of the electronic device 100, and they can be assembled together by means of snap-fit ​​or fastening, and can be separated when disassembly is required. When the middle plate 150 and the frame 120 are an integral structure, the connection between the middle plate 150 and the frame 120 cannot be separated. For example, the middle plate 150 and the frame 120 can be manufactured by integral molding, or assembled by permanent connection methods such as bonding or welding.

[0110] 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 a 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 ground the frame 120 through the middle plate 150. It is understood that in other examples, the electronic device 100 may not have a middle plate 150, in which case the frame 120 can be grounded by connecting to other grounding locations through grounding components.

[0111] like Figure 3 As shown, the frame 120 and the middle plate 150 are fixedly connected to form the middle frame structure of the electronic device 100. The middle frame structure is the middle part of the sandwich structure of the electronic device 100, and the two sides are used to support the touch screen 110 and the back cover 130, respectively.

[0112] Specifically, the frame 120 and the back cover 130 constitute the outer 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 disposed inside the outer shell, and the touch screen 110 is fixedly attached to the front side of the middle plate 150. The rear side of the middle plate 150 and the back cover 130 accommodate components such as the motherboard 500, the battery 600, and the small board 700.

[0113] The main board 160, the battery 170, and the small board 180 are arranged sequentially in the cavity between the middle plate 150 and the rear cover 130 to form a traditional three-section design architecture. The main board 160 and the small board 180 are electrically connected through a flexible printed circuit board (FPC). The flexible circuit board can be sandwiched between the battery 170 and the rear cover 130, or between the battery 170 and the middle plate 150.

[0114] The motherboard 160 is an important component of the electronic device 100, on which various devices that make up the circuit system of the electronic device 100 are installed. For example, the motherboard 160 contains the main circuits, processor, chips, capacitors, resistors, inductors, interfaces and plugs of the electronic device 100.

[0115] In some examples, the motherboard 160 may be equipped with a system-on-a-chip (SOC) chip, a power management unit (PMU) chip, or an RF chip. In addition, the motherboard 160 is usually equipped with various processors such as a central processing unit (CPU), various application processors (AP), graphics processing unit (GPU), or image signal processor (ISP), but is not limited to these.

[0116] The storage battery 170 is located in the battery compartment between the main board 160 and the sub-board 180. The storage battery 170 is an energy storage tool that provides power to the electronic device 100, and it is usually composed of three parts: battery cells, protection circuits, and a casing. The storage battery 170 can be a lithium battery, a nickel-metal hydride battery, or a sodium-ion battery, but is not limited to these.

[0117] The small board 180 is located at the bottom of the electronic device 100. The small board 180 typically houses functional components such as a microphone, speaker, charging port, USB port, SIM card port, RF interface, or antenna contacts. The frame 120 can have holes that work in conjunction with these functional components to achieve the corresponding functions. For example, a charging port can be provided on the frame 120 for inserting a charging plug. Another example is a sound outlet hole on the frame 120 for sound to escape from the speaker.

[0118] Furthermore, the electronic device 100 provided in this application embodiment also includes an antenna assembly, for example, it may include... Figure 4The antenna assembly 200 enables the electronic device 100 to achieve wireless communication connection with other devices. Figure 4 This is a schematic diagram of the structure of the antenna assembly 200 provided in the embodiments of this application, as shown below. Figure 4 As shown, antenna assembly 200 may include one or more antennas, such as a main antenna, diversity antenna, wireless fidelity (WIFI) antenna, global positioning system (GPS) antenna, Bluetooth antenna, multi-input multi-output (MIMO) antenna, and near field communication (NFC) antenna, or one or more of these.

[0119] In some examples, antenna assembly 200 may include one or more of the following: monopole antenna, planar inverted F-shaped antenna (PIFA), inverted F-shaped antenna (IFA), loop antenna, slot antenna, left-handed antenna, alpha antenna, bracket antenna, or attached antenna.

[0120] like Figure 4 As shown, the antenna assembly 200 includes one or more antenna stubs (also referred to as antenna radiators or radiators), including a first antenna stub 201, and one or more radio frequency front-ends (RFFEs), including a first radio frequency front-end 210.

[0121] The first antenna stub 201 is used to radiate radio frequency signals to or receive radio frequency signals from the outside world, enabling the electronic device 100 to communicate with the outside world through the first antenna stub 201. The first radio frequency front end 210 is connected to the first antenna stub 201 and is used to feed radio frequency signals to the first antenna stub 201 or receive radio frequency signals from the outside world received by the first antenna stub 201.

[0122] In some examples, the first radio frequency front-end 210 includes a transmitting path and a receiving path. The transmitting path includes devices such as a power amplifier (PA) and filters. The signal is amplified and filtered by the power amplifier and filters before being transmitted to the first antenna stub 201, and then transmitted to the outside world through the first antenna stub 201. The receiving path includes devices such as a low noise amplifier (LNA) and filters. The external signal received by the first antenna stub 201 is amplified and filtered by the low noise amplifier and filters before being transmitted to the radio frequency chip. Thus, wireless communication between the electronic device 100 and the outside world is realized through the first radio frequency front-end 210 and the first antenna stub 201.

[0123] In some embodiments, the first radio frequency front-end 210 is disposed between the middle board 150 and the rear cover 130, for example, the first radio frequency front-end 210 may be disposed on the motherboard 160 or the small board 180.

[0124] like Figure 4 As shown, the shape of the first antenna stub 201 can be a straight line, a polygonal line (e.g., L-shaped), or other regular or irregular shapes; this application does not limit this. The first antenna stub 201 includes a first feed point 211 and a first ground point 212 spaced apart.

[0125] The first feed point 211 is used to connect to 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 stub 201 through the first feed point 211, and then transmitted to the outside through the first antenna stub 201. It also allows the first antenna stub 201 to transmit radio frequency signals received from the outside to the first radio frequency front-end 210 through the first feed point 211. It should be noted that the first feed point 211 in this application is not an actual existing point; the first feed point 211 is the location where the first radio frequency front-end 210 connects to the first antenna stub 201.

[0126] In some examples, the first RF front end 210 is electrically connected to the first feed point 211 via connection structures such as wires (e.g., metal wires) and / or electrical connectors.

[0127] The first grounding point 212 is used to ground the first antenna stub 201. By adjusting the position of the first grounding point 212, the electrical length of the first antenna stub 201 can be adjusted. The change in electrical length alters the resonant frequency of the first antenna stub 201. In practical applications, the first grounding point 212 can be grounded using grounding springs or grounding wires. The first end of the grounding device is connected to the first grounding point 212, and the second end is connected to a reference ground. For example, the second end of the grounding device can be electrically connected to the middle plate 150, thus grounding the first antenna stub 201 through the middle plate 150. It should be noted that the first grounding point 212 in this application is not an actual physical point; the location where the grounding spring or grounding wire connects to the first antenna stub 201 is the first grounding point 212.

[0128] In this embodiment of the application, the positions of the first feed point 211 and the first ground point 212 on the first antenna stub 201 are not specifically limited, as long as the first feed point 211 and the first ground point 212 are spaced apart along the extension direction of the first antenna stub 201.

[0129] In some examples, the first antenna stub 201 is electrically connected to the middle plate 150 through the first grounding point 212. There may also be a gap between the first antenna stub 201 and the middle plate 150 to ensure that the first antenna stub 201 has good clearance, so that the antenna assembly 200 has good radiation performance.

[0130] In some examples, the operating frequency band of the first antenna stub 201 and / or the first radio frequency front end 210 can be any one of the following: satellite band, 2G band, 3G band, 4G band, 5G band, GPS band, WIFI band, Bluetooth band, star flash band, or NFC band.

[0131] For example, the operating frequency band of the first antenna stub 201 and / or the first radio frequency front-end 210 can specifically be the high-orbit satellite communication band (e.g., 1980MHz-2010MHz or 2170MHz-2200MHz), the low-orbit satellite network band (e.g., 37.5GHz-42.5GHz or 47.2GHz-51.4GHz), the BeiDou band (e.g., B1, B2, or B3 bands), or the 3G B1, B2, B4, B5, B6, B8, or B19 bands; or it can be the 4G B1, B2, B4, B5, B6, B8, or B19 bands. 2. B3, B4, B5, B7, B8, B12, B17, B18, B19, B20, B26, B28A, B34, B38, B39, B40, B41 or B42 frequency bands; or 5G N1, N3, N28A, N41, N77, N78 or N79 frequency bands; or GPS L1 frequency band or GPS L5 frequency band; or WIFI 2.4G or 5G frequency band, or Bluetooth 2.4G frequency band, or StarFlash 2.4G or 5G frequency band.

[0132] In some examples, the first antenna stub 201 can be any of the following antenna types: PIFA antenna, LOOP antenna, IFA antenna, SLOT antenna, etc., but is not limited to these.

[0133] like Figure 4 As shown, the antenna assembly 200 also includes a second antenna stub 202, which radiates or receives radio frequency signals from the outside world, enabling wireless communication between the electronic device 100 and the outside world. The second antenna stub 202 is spaced apart from the first antenna stub 201, with a gap 230 between them. The gap 230 isolates adjacent second antenna stubs 202 from the first antenna stub 201, ensuring complete insulation between them and achieving isolation between different antenna stubs. In some examples, the gap 230 may also be filled with insulating material to increase the insulation effect.

[0134] like Figure 4 As shown, the shape of the second antenna stub 202 can be a polygonal shape (e.g., L-shaped), or a straight shape, or other regular or irregular shapes; this application does not limit this. The second antenna stub 202 includes a second feed point 221 and a second grounding point 222 spaced apart.

[0135] like Figure 4 As shown, the antenna assembly 200 also includes a second radio frequency front end 220, which is electrically connected to the second feed point 221 of the second antenna stub 202. The second radio frequency front end 220 is used to feed radio frequency signals to the second antenna stub 202 or to receive radio frequency signals from the outside world received by the second antenna stub 202.

[0136] In some examples, the second RF front-end 220 includes a transmitting path and a receiving path. The transmitting path includes devices such as power amplifiers and filters. The signal is amplified and filtered by these devices before being transmitted to the second antenna stub 202, and then transmitted to the outside world via the second antenna stub 202. The receiving path includes devices such as low-noise amplifiers and filters. The external signal received by the second antenna stub 202 is amplified and filtered by these devices before being transmitted to the RF chip. Thus, wireless communication between the electronic device 100 and the outside world is achieved through the second RF front-end 220 and the second antenna stub 202. It should be noted that the second feed point 221 in this application is not an actual existing point; the location where the second RF front-end 220 and the second antenna stub 202 are electrically connected is the second feed point 221 mentioned in this application.

[0137] In some examples, the second RF front-end 220 is located between the middle board 150 and the rear cover 130. For example, the second RF front-end 220 may be located on the main board 160 or the small board 180.

[0138] The second grounding point 222 is used to ground the second antenna stub 202. By adjusting the position of the second grounding point 222, the electrical length of the second antenna stub 202 can be adjusted. The change in electrical length alters the resonant frequency of the second antenna stub 202. In practical applications, the second grounding point 222 can be grounded using grounding springs or grounding wires. The first end of the grounding device is connected to the second grounding point 222, and the second end is connected to a reference ground. For example, the second end of the grounding device can be electrically connected to the middle plate 150, thus grounding the second antenna stub 202 through the middle plate 150. It should be noted that the second grounding point 222 in this application is not an actual existing point; the location where the grounding spring or grounding wire connects to the second antenna stub 202 is the second grounding point 222.

[0139] In this embodiment, the positions of the second feed point 221 and the second ground point 222 on the second antenna stub 202 are not specifically limited, as long as the second feed point 221 and the second ground point 222 are spaced apart along the extension direction of the second antenna stub 202. Details regarding the arrangement of the second antenna stub 202 can be found in the description of the aforementioned first antenna stub 201, and will not be repeated here.

[0140] By setting a second antenna stub 202, this application enables the antenna assembly 200 provided in this embodiment to transmit or receive signals in the second frequency band in addition to transmitting or receiving signals in the first frequency band through the first antenna stub 201. Therefore, the antenna assembly 200 has more application frequency bands and a wider range of applications.

[0141] In some examples, the antenna assembly 200 also includes a tuning element electrically connected to the first antenna stub 201 and / or the second antenna stub 202, for matching the resonant frequencies of the first antenna stub 201 and / or the second antenna stub 202 with the desired communication frequency. For example, this tuning element can enable intelligent tuning of the antenna assembly 200. Exemplarily, the tuning element may include at least one component selected from capacitors, inductors, resistors, etc.

[0142] In some examples, the first antenna stub 201 and / or the second antenna stub 202 can be part of the housing of the electronic device 100 (i.e., part of the housing is reused as an antenna stub), or the first antenna stub 201 and / or the second antenna stub 202 can be located inside the housing of the electronic device 100. This configuration improves the flexibility of antenna setup and helps reduce the difficulty of antenna design.

[0143] In some examples, the frame 120 can be made of a conductive material, i.e., the frame 120 is a conductive frame (e.g., a metal frame). In this case, a portion of the frame 120 can be used as the aforementioned first antenna stub 201 and second antenna stub 202, thereby reducing the space occupied by the antenna assembly 200, ensuring that the antenna stub has good radiation performance, and helping to reduce the difficulty of antenna design.

[0144] Figure 5 This is a structural schematic diagram of an antenna stub arrangement method provided in an embodiment of this application. For example... Figure 5 As shown, the aforementioned frame 120 can be a conductive frame 120a, such as a metal frame made of aluminum alloy, magnesium alloy, or stainless steel. In this case, the conductive frame 120a can be used as part of the antenna assembly 200. That is, in addition to fulfilling the basic functions of the housing, the conductive frame 120a can also be reused as an antenna stub of the antenna assembly 200 for wireless communication.

[0145] Specifically, multiple slits 230 are formed on the conductive frame 120a to divide the conductive frame 120a into multiple electrically isolated segments. The number of segments can be changed by changing the number of slits 230. For example, the number of slits 230 formed on the conductive frame 120a can be 3 to 15, such as 5, 6, 7 or 8.

[0146] like Figure 5 As shown, in this embodiment, eight slots 230 are sequentially arranged on the conductive frame 120a, dividing the conductive frame 120a into eight segments. One segment constitutes the aforementioned first antenna branch 201, another segment constitutes the aforementioned second antenna branch 202, and the first antenna branch 201 and the second antenna branch 202 are separated by one of the slots 230. The remaining six segments constitute 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.

[0147] In some examples, two or more segments of the conductive border 120a may operate at the same frequency band. Alternatively, the segments of the conductive border 120a may operate at different frequency bands, and this application does not impose any special limitations on this.

[0148] In some examples, all segments of the conductive frame 120a may be used as antenna stubs. Alternatively, some segments (e.g., one or two segments) may not be used as antenna stubs, and this application does not impose any particular limitation on this.

[0149] In some examples, multiple antenna stubs of the antenna assembly 200 may all be located on the conductive frame 120a, meaning that multiple segments of the conductive frame 120a constitute the multiple antenna stubs. Alternatively, some antenna stubs of the antenna assembly 200 may not be located on the conductive frame 120a, meaning that these antenna stubs are not constituted by segments of the conductive frame 120a. For example, these antenna stubs may be located inside the housing of the electronic device 100 and / or on the rear cover 130. This application does not impose any special limitations on this.

[0150] For example, antenna assembly 200 includes a total of 8 antenna stubs, namely... Figure 5 The antenna stubs are: the first antenna stub 201, the second antenna stub 202, the third antenna stub 203, the fourth antenna stub 204, the fifth antenna stub 205, the sixth antenna stub 206, the seventh antenna stub 207, and the eighth antenna stub 208.

[0151] For example, besides including Figure 5 In addition to the eight antenna segments, including the first antenna segment 201, the second antenna segment 202, the third antenna segment 203, the fourth antenna segment 204, the fifth antenna segment 205, the sixth antenna segment 206, the seventh antenna segment 207, and the eighth antenna segment 208, the antenna assembly 200 may also include other antenna segments, which may be disposed inside the housing of the electronic device 100 and / or located on the rear cover 130.

[0152] In some examples, the gap 230 is filled with insulating material to make the appearance of the metal frame 120a neat and to ensure the structural integrity of the frame 120. Furthermore, it enables complete insulation between adjacent sections, thereby achieving isolation between different antenna stubs.

[0153] For example, insulating material can be reliably placed inside the gap 230 using a nano-injection molding process.

[0154] Figure 6 This is a schematic diagram of another antenna stub configuration provided in an embodiment of this application. For example... Figure 6 As shown, the aforementioned frame 120 can be an insulating frame 120b made of a non-conductive material, such as a plastic frame, resin frame, glass frame, or ceramic frame. In this case, the insulating frame 120b cannot be used as part of the antenna assembly 200 for communication. Considering that the antenna stubs need to be located near the edge of the electronic device 100, this application can place the aforementioned first antenna stub 201 and / or second antenna stub 202 inside the housing and adjacent to (e.g., tightly against) the inner wall of the insulating frame 120b to minimize the area occupied by the antenna stubs, making the antenna stubs closer to the edge of the electronic device 100 and achieving better radiation performance. Furthermore, since there is no need to create gaps in the frame, the integrity of the frame structure can be guaranteed, ensuring that the frame has sufficient structural strength.

[0155] It should be noted that the antenna stubs mentioned here (such as the first antenna stub 201) are located near the inner wall of the insulating frame 120b. This can mean that the antenna stubs are fixed to the inner wall of the insulating frame 120b by means of bonding or other processes; or that the antenna stubs are located close to the inner wall of the insulating frame 120b; or that the antenna stubs are located close to the insulating frame 120b, but there is a certain small gap between them (e.g., 0.01 mm to 2 mm). This application does not make any special limitations on this.

[0156] In some examples, the first antenna stub 201 is disposed inside the housing and adjacent to the inner wall of the insulating frame 120b. "Adjacent" here means that the distance (e.g., minimum distance) between the first antenna stub 201 and the insulating frame 120b is greater than or equal to 0 and less than or equal to 5 millimeters (mm). For example, the distance between them can be less than or equal to 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, or 4mm, etc., but is not limited to these values.

[0157] In some examples, the first antenna stub 201 and / or the second antenna stub 202 can be in the form of an FPC antenna, a laser direct structuring (LDS) antenna, a microstrip antenna (MDA) antenna, or a printed direct structuring (PDS) antenna.

[0158] In some examples, the first antenna stub 201 and / or the second antenna stub 202 may be positioned between the insulating frame 120b and the battery 170.

[0159] Figure 7 This is a schematic diagram of another antenna stub configuration provided in an embodiment of this application. For example... Figure 7 As shown, the aforementioned back cover 130 can be an insulating back cover 130a made of non-conductive material, such as a glass back cover, plastic back cover, resin back cover, ceramic back cover, or other non-metallic back cover. In this case, considering that the antenna stubs need to be positioned close to the edge of the electronic device 100, this application can place the aforementioned first antenna stub 201 and / or second antenna stub 202 inside the housing and adjacent to the inner wall of the insulating back cover 130a to minimize the area occupied by the antenna stubs, making the antenna stubs closer to the edge of the electronic device 100 and achieving better radiation performance. Furthermore, since there is no need to create gaps in the frame, the integrity of the frame structure can be ensured, guaranteeing sufficient structural strength.

[0160] It should be noted that the antenna stubs mentioned here (such as the first antenna stub 201) are located near the inner wall of the insulating back cover 130a. This can mean that the antenna stubs are fixed to the inner wall of the insulating back cover 130a by means of bonding or other processes; or that the antenna stubs are located close to the inner wall of the insulating back cover 130a; or that the antenna stubs are located close to the insulating back cover 130a, but there is a certain small gap between them (e.g., 0.01 mm to 2 mm). This application does not make any special limitations on this.

[0161] In some examples, the first antenna stub 201 is disposed inside the housing and adjacent to the inner wall of the insulating back cover 130a. "Adjacent" here means that the distance (e.g., minimum distance) between the first antenna stub 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 them can be less than or equal to 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, or 4mm, etc., but is not limited to these values.

[0162] In some examples, the first antenna stub 201 and / or the second antenna stub 202 may also be embedded in the insulating back cover 130a, or disposed on the outside of the insulating back cover 130a, for example, disposed in the camera decorative piece.

[0163] In some examples, the first antenna stub 201 and / or the second antenna stub 202 can be in the form of an FPC antenna, an LDS antenna, a microstrip antenna MDA antenna, or a PDS antenna, etc.

[0164] In some examples, the first antenna stub 201 and / or the second antenna stub 202 may be disposed between the insulating back cover 130a and the battery 170.

[0165] In some examples, the interior of the insulating back cover 130a may have a recess in which the first antenna stub 201 and / or the second antenna stub 202 may be disposed.

[0166] In some examples, multiple antenna branches of the antenna assembly 200 may all be located within 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, some antenna branches of the antenna assembly 200 may not be located on the insulating back cover 130a. For example, these antenna branches may be located inside the housing of the electronic device 100 and adjacent to the inner wall of the insulating frame 120b, or these antenna branches may be located on the conductive frame 120a (i.e., these antenna branches are formed by a segment of the conductive frame 120a). This application does not impose any special limitations on this.

[0167] In other words, this application Figure 5 and Figure 7The illustrated embodiments can be combined with each other. At least one antenna stub 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 stub. At least one antenna stub of the antenna assembly 200 (e.g., the remaining antenna stubs) can be located on the insulating back cover 130a. Alternatively, this application... Figure 6 and Figure 7 The embodiments shown can be combined with each other, at least one antenna stub of the antenna assembly 200 can be located inside the housing and adjacent to the inner wall of the insulating frame 120b, and at least one antenna stub of the antenna assembly 200 (e.g., the remaining antenna stubs) can be located on the insulating back cover 130a.

[0168] In some examples, such as Figure 7 As shown, 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 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 but spaced apart, separated by a gap 230, thus 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; this application does not impose any special limitations on this.

[0169] by Figure 5 Taking the antenna stub arrangement shown as an example, the electronic device 100 provided in the embodiments of this application will be further described below with reference to the accompanying drawings. Figure 8 This is a schematic diagram illustrating an example of the circuit structure of the electronic device 100 provided in this application embodiment, as shown below. Figure 5 and Figure 8 As shown, 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.

[0170] 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.

[0171] The electronic device 100 provided in this application embodiment is additionally equipped with a touch sensor 300. The touchscreen 110 and the touch sensor 300 are simultaneously used to detect user touch actions near the first antenna stub 201. Compared to the prior art that only uses the touchscreen to detect user touch actions, this application can improve the accuracy of touch detection, for example, achieving grip position recognition at the 1 mm level. Based on this, the processor 400 can simultaneously control the antenna assembly 200 based on the detection signals from the touchscreen 110 and the touch sensor 300, thereby improving the accuracy and precision of antenna assembly 200 control, for example, facilitating precise and timely antenna stub switching and / or high-precision intelligent tuning. Thus, the electronic device 100 provided in this application can minimize the impact of user grip on communication performance, ensuring that the antenna assembly 200 always has optimal operating conditions, thus improving the user experience.

[0172] Here, the touchscreen 110 and touch sensor 300 detect touch actions by the user on the electronic device 100 and near the first antenna stub 201. This can also be understood as detecting touch actions by the user on the electronic device 100 and near the first antenna stub 201. The touch action can be any action that affects the communication performance of the first antenna stub 201, such as a touch, approach, or grip action (e.g., the aforementioned "death grip" or "feint") on the electronic device 100 and near the first antenna stub 201, but is not limited to these. The touch action can be an active touch action by the user on the electronic device or an unconscious touch action. It can be an action by the user on the surface of the electronic device 100 (the user is in contact with the surface of the electronic device 100) or an action by the user near the surface of the electronic device 100 (the user is not in contact with the surface of the electronic device 100, such as the aforementioned "hovering touch"). Furthermore, the touch action can be an action by the user's hand on the electronic device 100, or an action by the user's body or head or other parts of the body on the electronic device 100.

[0173] Here, "touch actions near the first antenna stub 201" refers to touch actions near the first antenna stub 201 that affect communication performance. For example, a touch action near the first antenna stub 201 can be a touch action within a certain range around the first antenna stub 201, such as a touch action within 5mm, 15mm, 20mm, or 35mm of the distance to the first antenna stub 201. It is easy to understand that the above-mentioned touch actions are detected by the touchscreen 110 and the touch sensor 300, therefore, they should have detection capabilities corresponding to the aforementioned distance range.

[0174] In some examples, the touchscreen 110 detects a user's touch action on the electronic device 100 and near the first antenna stub 201 to generate a first detection signal; the touch sensor 300 detects the user's touch action on the electronic device 100 and near the first antenna stub 201 to generate a second detection signal; the processor 400 controls the antenna assembly 200 based on the first and second detection signals. Because the processor 400 can control the antenna assembly 200 simultaneously based on the detection signals from the touchscreen 110 and the touch sensor 300, the accuracy and precision of the control of the antenna assembly 200 can be improved.

[0175] In some examples, "touch actions near the first antenna stub 201" can refer to touch actions within a certain range around the first antenna stub 201, such as touch actions within a radius of 20mm. Furthermore, depending on the sensing accuracy, the touchscreen 110 and / or touch sensor 300 can sense touch actions within a radius of, for example, 30mm or 20mm. This application uses a radius of 20mm as an example for illustration and is not intended to limit the sensing accuracy of the touchscreen 110 and / or touch sensor 300, but rather to describe the usage scenario of this application embodiment for ease of understanding.

[0176] In some examples, a “touch action near the first antenna stub 201” can be an action of a user touching or stroking the first antenna stub 201. The processor 400 can control the antenna assembly 200 based on the detection signals of the above action by the touch screen 110 and the touch sensor 300, such as switching the antenna stub.

[0177] In some examples, the touchscreen 110 and the touch sensor 300 detect touch actions by the user near the first antenna stub 201. This could be detecting whether the first antenna stub 201 is being held by the user, or detecting the distance (i.e., proximity) between the touch action and the first antenna stub 201, or detecting whether the user's grip on the first antenna stub 201 is a firm grip or a loose grip, etc.

[0178] In some examples, the touch screen 110 and the touch sensor 300 detect the user's touch action near the first antenna stub 201. This can be detecting whether the first antenna stub 201 is being held by the user, and if it is being held, parameters such as the user's holding position, the tightness (pressure) of the grip, the grip length, or the grip area.

[0179] In some examples, the touch sensor 300 may be any sensor capable of detecting touch actions performed by a user near the first antenna stub 201, such as a touchpad, fingerprint sensor, pressure sensor, light sensor, proximity sensor, distance sensor, or specific absorption rate (SAR) sensor, but is not limited to these.

[0180] In some examples, the touch sensor 300 can be a touchpad, such as a capacitive or resistive touchpad. The touchpad consists of a large number of densely integrated touch detection units, each of which can correspond to a detection area. This allows the touchpad to detect not only whether the first antenna stub 201 is touched by the user, but also the user's touch position and touch area. That is, it can detect parameters such as the position, length, or area of ​​the first antenna stub 201 held by the user's hand. This enables the processor 400 to achieve high-accuracy and high-precision control of the antenna assembly 200 based on the detection signal, further reducing the impact of the user's hand grip on communication performance.

[0181] For example, the touchpad includes multiple touch detection units, the density of which is greater than or equal to 2 pixels per inch (ppi). For instance, the density of the multiple touch detection units can be 3ppi, 5ppi, 10ppi, 50ppi, 72ppi, 100ppi, 180ppi, 300ppi, or 432ppi, etc.

[0182] In some examples, the touch sensor 300 may be located inside or outside the housing of the electronic device 100. For example, the touch sensor 300 may be disposed on the inner or outer wall of the housing, or a portion of the housing may constitute the touch sensor 300.

[0183] In some examples, the touch sensor 300 and the first antenna stub 201 can be either insulated from each other (i.e., electrically isolated) or electrically connected. For example, they can be insulated from each other, in which case they are independent of each other and do not affect each other, with the touch sensor 300 used only to detect touch actions. Alternatively, they can be electrically connected, in which case the touch sensor 300 can also be reused as part of the antenna stub for communication, thereby making the antenna design of this application more flexible.

[0184] Here, the statement that the touch sensor 300 and the first antenna stub 201 are mutually insulated means that they are physically separated from each other by air or insulating material. It does not mean that no induced current will be generated between them; in other words, in some examples, an induced current can be generated between the touch sensor 300 and the first antenna stub 201, which is not specifically limited in this application.

[0185] In some examples, the processor 400 may be any processor, processing unit, or processing module, such as a CPU, capable of controlling the antenna assembly 200 based on the detection signals from the touch screen 110 and the touch sensor 300.

[0186] In some examples, the processor 400 controls the antenna assembly 200 based on a detection signal, which may involve switching antenna stubs. Specifically, if the processor 400 determines, based on the detection signal, that the first antenna stub 201 used for wireless communication is being held by a user, the processor 400 can switch the antenna stub used for communication by the antenna assembly 200 from the first antenna stub 201 to another antenna stub not being held by the user (e.g., ...). Figure 5 (e.g., the fifth antenna stub 205 in the example). For example, the processor 400 can control the switching of antenna stubs by controlling an antenna switching switch (e.g., a single-pole multi-throw switch), and the operating frequency bands of the antenna stubs (e.g., the first antenna stub 201 and the fifth antenna stub 205) before and after the switching can be the same.

[0187] For example, in conjunction with the appendix Figure 5 The antenna assembly 200 switches antenna stubs, which may include a switch in the antenna stub connected to the first RF front-end 210, meaning the first RF front-end 210 is no longer electrically connected to the first antenna stub 201, but is electrically connected to other antenna stubs. It may also include the first RF front-end 210, which was originally electrically connected to the first feed point 211 of the first antenna stub 201, no longer being electrically connected to the first feed point 211, meaning the electrical connection between the first RF front-end 210 and the first feed point 211 is broken (e.g., by changing the state of a switch), and the first antenna stub 201 ceases to function.

[0188] In some examples, the processor 400 controls the antenna assembly 200 based on the detection signal, which may involve intelligent tuning of the antenna assembly 200. Specifically, the processor 400 determines, based on the detection signal, that the first antenna stub 201, which is conducting wireless communication, is being held by the user, and may even determine parameters such as the position and / or area of ​​the first antenna stub 201 being held by the user. In this case, the processor 400 can achieve intelligent tuning of the antenna assembly 200 by controlling the tuning elements (e.g., by changing the state of corresponding switches) so that the resonant frequency of the first antenna stub 201 can be matched with the required communication frequency (i.e., the operating frequency), thereby enabling the first antenna stub 201 to have good transmission efficiency.

[0189] For example, intelligent tuning of the antenna assembly 200 may include controlling the tuning circuit of the antenna assembly 200. The tuning circuit is electrically connected to the first antenna stub 201 and may include components such as switches, capacitors, or inductors. The processor 400 can connect the first antenna stub 201 to different capacitors / inductors by changing the state of the switch (e.g., switching between multiple states of the switch), thereby realizing intelligent tuning of the antenna assembly 200.

[0190] In some examples, the processor 400 controls the antenna assembly 200 based on the detection signal, which may involve controlling the antenna assembly 200 to reduce the power of the first antenna stub 201. Specifically, the touch sensor 300 can be equivalent to a specific absorption rate (SAR) sensor. The processor 400 can determine from the detection signal that the user's head / body is close to the electronic device 100 (e.g., holding it to their ear while making a phone call), and therefore can adjust the power of the first antenna stub 201 of the antenna assembly 200 to achieve the function of a SAR sensor.

[0191] In some examples, the processor 400 controls the antenna assembly 200 based on the detection signal. It may also adjust the transmission power of the first antenna stub 201 or add new antenna stubs to perform other aspects of control on the antenna assembly 200, which are not specifically limited in this application.

[0192] In some examples, when the first antenna stub 201 is detected to be operational (enabled), the processor 400 controls the touchscreen 110 and the touch sensor 300 to be operational in order to acquire the detection signal.

[0193] In some examples, the touch sensor 300 is positioned adjacent to the first antenna stub 201, which helps to achieve high-precision touch detection.

[0194] In some examples, the first antenna stub 201 includes at least a portion (e.g., at least one segment) of the conductive frame 120a. That is, at least a portion of the conductive frame 120a can also be reused as the first antenna stub 201, thereby reducing the space occupied by the antenna assembly 200, ensuring good radiation performance of the antenna stub, and helping to reduce the difficulty of antenna design.

[0195] For example, the first antenna stub 201 may include at least one segment of the conductive frame 120a. This segment may be a section of the conductive frame 120a located between the two gaps 230 (e.g., Figure 5 (As shown), it can also be a section located between two grounding points, or a section between a gap and a grounding point. A feed point can be set on the section for use as a main feed antenna, or it can be used as a parasitic antenna without a feed point. This application does not make any special limitations on this.

[0196] In some examples, such as Figure 8 As shown, a segment of the conductive frame 120a constitutes the first antenna stub 201. The touch sensor 300 is a touchpad located inside and adjacent to the first antenna stub 201. The sensing surface of the touchpad faces outward (i.e. towards the first antenna stub 201) to detect the user's touch action.

[0197] In some examples, such as Figure 8 As shown, the touch sensor 300 is disposed near the first feed point 211 of the first antenna stub 201. For example, the touch sensor 300 can be a touchpad located inside the first antenna stub 201, with the sensing surface of the touchpad facing outward (i.e. towards the first feed point 211) and disposed near the first feed point 211 of the first antenna stub 201.

[0198] When the feed point of an antenna stub is held by a user, it will have a significant impact on the communication performance of that antenna stub. In this embodiment, the touch sensor 300 is located near the first feed point 211 of the first antenna stub 201, which can be used to detect whether the first feed point 211 is held by a user. This helps to achieve high accuracy and high precision control of the antenna assembly 200, further reducing the impact of the user's grip on the communication performance and improving the user experience.

[0199] In some examples, such as Figure 8As shown, the touch sensor 300 is positioned adjacent to the first feed point 211. This can be achieved by the orthographic projection of the touch sensor 300 onto the conductive frame 120a covering the first feed point 211. Alternatively, the orthographic projection of the touch sensor 300 onto the conductive frame 120a may not coincide with the first feed point 211 (they may be offset from each other). The distance between the near edge of this orthographic projection and the first feed point 211 is 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.

[0200] In some examples, such as Figure 8 As shown, the touch sensor 300 can be a touchpad, which can be a strip-shaped structure extending along the conductive frame 120a. The sensing surface of the touchpad faces outwards from the device, for example, towards the conductive frame 120a, or it can also face towards the back cover 130. The length of the strip-shaped structure can be greater than or equal to 0.2 cm, for example, it can be 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., thereby enabling better touch position recognition.

[0201] In some examples, the touch sensor 300 is positioned near the location of the strongest current in the first antenna stub 201, where the location of the strongest (maximum) current is typically determined by the antenna design. For example, the touch sensor 300 may be a touchpad located inside the first antenna stub 201, with the sensing surface of the touchpad facing outwards from the device and near the location of the strongest current in the first antenna stub 201.

[0202] When the strongest current position of an antenna stub is held by a user, it will have a significant impact on the communication performance of that antenna stub. The touch sensor 300 in this embodiment is set near the strongest current position of the first antenna stub 201, which can be used to detect whether the strongest current position is held by a user. This helps to achieve high accuracy and high precision control of the antenna assembly 200, further reduces the impact of the user's grip on the communication performance, and improves the user experience.

[0203] In some examples, the touch sensor 300 is positioned near the location of the strongest current, which could be because the orthographic projection of the touch sensor 300 on the conductive frame 120a covers the location of the strongest current. Alternatively, the orthographic projection of the touch sensor 300 on the conductive frame 120a may not coincide with the location of the strongest current (they may be offset from each other), and the distance between the near edge of the orthographic projection and the location of the strongest current is less than a certain threshold, which may 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.

[0204] In some examples, the touch sensor 300 is positioned adjacent to the open end of the first antenna stub 201. This open end is the end of the first antenna stub 201 that performs the main radiating function and is not grounded. For example, the touch sensor 300 can be a touchpad located inside the first antenna stub 201, with the sensing surface of the touchpad facing outwards from the device and adjacent to the open end of the first antenna stub 201.

[0205] As the main radiating part of the antenna stub, the open end being held by the user will have a significant impact on the communication performance of the antenna stub. In this embodiment, the touch sensor 300 is located near the open end of the first antenna stub 201, and can be used to determine whether the open end of the first antenna stub 201 is held by the user. This helps to achieve high accuracy and precision control of the antenna assembly 200, further reducing the impact of the user's grip on the communication performance and improving the user experience.

[0206] In some examples, the touch sensor 300 is positioned adjacent to the open end of the first antenna stub 201, where the orthographic projection of the touch sensor 300 on the conductive frame 120a coincides with the open end. Alternatively, the orthographic projection of the touch sensor 300 on the conductive frame 120a may not coincide with the open end (they may be offset), and the distance between the proximal edge of the orthographic projection and the open end may be less than a certain threshold, such as 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.

[0207] Figure 9 This is a schematic diagram illustrating another example of the circuit structure of the electronic device 100 provided in this application embodiment. For example... Figure 9 As shown in part (a), two adjacent segments of the conductive frame 120a constitute the aforementioned first antenna stub 201 and second antenna stub 202, respectively, and a gap 230 exists between the open end 201 of the first antenna stub 201 and the second antenna stub 202. In this case, the gap 230 is shared by both the first antenna stub 201 and the second antenna stub 202. A touch sensor 300 is disposed adjacent to and located inside the open end 201; the touch sensor 300 may, for example, be a touchpad with its sensing surface facing outwards from the device.

[0208] like Figure 9As shown in part (b), one segment of the conductive frame 120a constitutes the aforementioned first antenna stub 201. A gap 230 exists between the open end 201 of the first antenna stub 201 and the lower segment. In this case, the lower segment is grounded and not used as an antenna stub, while the gap 230 is exclusively used by the first antenna stub 201. A touch sensor 300 is disposed adjacent to and inside the open end 201. The touch sensor 300 may, for example, be a touchpad with its sensing surface facing outwards from the device.

[0209] like Figure 9 As shown in section (c), the first antenna stub 201 is disposed inside the insulating frame 120b. There are no other antenna stubs or conductors near the open end 201 of the first antenna stub 201, and the edge of the open end 201 may not have obvious gaps or slits. The touch sensor 300 is disposed adjacent to the open end 201 and located inside the open end 201. The touch sensor 300 may be, for example, a touchpad with its sensing surface facing outwards from the device.

[0210] Figure 10 This is a schematic diagram illustrating another example of the circuit structure of the electronic device 100 provided in this application embodiment. Figure 10 In the embodiment shown, two adjacent segments of the conductive frame 120a constitute the aforementioned first antenna stub 201 and second antenna stub 202, respectively. The touch sensor 300 is a touchpad located inside the conductive frame 120a and adjacent to the gap 230 between the first antenna stub 201 and the second antenna stub 202. The sensing surface of the touchpad faces outward (i.e. towards the gap 230) to detect the user's touch action.

[0211] When the gap between adjacent antenna stubs is held by a user, it will have a significant impact on the communication performance of the antenna stubs. In this embodiment, the touch sensor 300 is set near the gap 230 between the first antenna stub 201 and the second antenna stub 202, which can be used to detect whether the gap 230 is held by a user. This helps to achieve high accuracy and high precision control of the antenna assembly 200, further reduces the impact of the user's grip on the communication performance, and improves the user experience.

[0212] In some examples, such as Figure 10As shown, the touch sensor 300 is positioned adjacent to the gap 230, which can be such that the orthographic projection of the touch sensor 300 on the conductive frame 120a covers the gap 230. Alternatively, the orthographic projection of the touch sensor 300 on the conductive frame 120a may not coincide with the gap 230 (they may be offset from each other), and the distance between the proximal edge of the orthographic projection and the gap 230 is less than a certain threshold. This threshold may 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.

[0213] Figure 11 This is a schematic diagram illustrating various configurations of the touch sensor 300 provided in this application embodiment. The adjacent gap 230 of the touch sensor 300 can be configured in various ways, such as... Figure 11 As shown in part (a), the touch sensor 300 can also be disposed on the outside of the gap 230, for example, on the outer wall of the conductive frame 120a. In this case, the orthographic projection of the touch sensor 300 on the conductive frame 120a also covers the gap 230, that is, the touch sensor 300 covers the gap 230 from the outside.

[0214] As another way of setting up proximity, such as Figure 11 As shown in part (b), the touch sensor 300 can also be disposed on the upper side of the gap 230, for example, on the first antenna stub 201. In this case, the touch sensor 300 and the first antenna stub 201 can be either insulated from each other or electrically connected. For example, they can be electrically connected, with the touch sensor 300 used for communication as part of the first antenna stub 201, or the touch sensor 300 can also constitute a complete antenna stub, in which case the touch sensor 300 is the first antenna stub 201.

[0215] As another way of setting up proximity, such as Figure 11 As shown in section (c), the touch sensor 300 can also be disposed on the lower side of the gap 230, for example, on the second antenna stub 202. In this case, the touch sensor 300 and the first antenna stub 201 can be either insulated from each other or electrically connected. For example, they can be electrically connected, and the touch sensor 300 can be used for communication as part of the second antenna stub 202. Alternatively, the touch sensor 300 can also constitute a complete antenna stub, in which case the touch sensor 300 is the second antenna stub 202.

[0216] As another way of setting up proximity, such as Figure 11As shown in section (d), the touch sensor 300 can also be disposed within the gap 230, and simultaneously electrically insulated from the first antenna stub 201 and the second antenna stub 202. Considering the various adjacent placement methods described above, it is clear that this application does not impose any special limitation on the relative position of the touch sensor 300 and the gap 230.

[0217] In some examples, the touch sensor 300 can be a touchpad with its sensing surface facing outwards to facilitate the detection of user touch actions. For example, the sensing surface may face outwards and be parallel or nearly parallel to the outer wall of the bezel 120, thereby enabling the detection of touch actions on the bezel 120; or, the sensing surface may face outwards and be parallel or nearly parallel to the outer wall of the back cover 130, thereby enabling the detection of touch actions on the back cover 130.

[0218] For example, such as Figure 10 As shown, the touch sensor 300 is a touchpad located inside the device and adjacent to the gap 230. The aforementioned "the sensing surface of the touchpad facing the outside of the device" can mean the sensing surface of the touchpad faces the conductive frame 120a or the gap 230; it can also mean the sensing surface of the touchpad faces the back cover 130. Regardless of the arrangement, the touchpad can effectively detect touch actions near the gap 230 and whether the gap 230 is being held by the user. In other words, this application does not specifically limit the specific orientation of the sensing surface of the touchpad; any orientation that enables effective detection of touch actions should be included within the scope of protection of this application.

[0219] In some examples, the touch sensor 300 is positioned near the first feed point 211 of the first antenna stub 201, or near the open end of the first antenna stub 201, or near the gap 230, or near the location of the strongest current in the first antenna stub 201. Here, "nearby" can mean that the distance (e.g., minimum distance) between the touch sensor 300 and the corresponding location is greater than or equal to 0 and less than or equal to 5 millimeters (mm). For example, the distance between them can be less than or equal to 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, or 4mm, etc., and can be 0.01mm, 0.02mm, 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.5mm, 0.8mm, 1mm, 1.5mm, 2mm, 3mm, or 4mm, etc., but is not limited to these.

[0220] Figure 12 This is a schematic diagram illustrating another example of the circuit structure of the electronic device 100 provided in this application embodiment. Figure 12In the illustrated embodiment, the antenna assembly 200 includes multiple antenna stubs, such as first antenna stubs 201 to eighth antenna stubs 208, and the touch sensor 300 has multiple (e.g., including) Figure 12 The touchscreen 110 and multiple touch sensors 300 are used to jointly detect touch actions by the user on the electronic device 100 and located near the multiple antenna branches, and generate detection signals. The processor 400 controls the antenna assembly 200 according to the detection signals.

[0221] This application, by setting up multiple touch sensors 300 corresponding to multiple antenna stubs, can detect touch actions near any antenna stub through these multiple touch sensors 300. Combined with the detection signal from the touch screen 110, the processor 400 can accurately identify which antenna stub(s) are being held by the user, and thereby achieve high accuracy and high precision control of the antenna assembly 200. This can further reduce the impact of the user's grip on communication performance and improve the user experience.

[0222] In some examples, the number of touch sensors 300 is equal to the number of antenna stubs of antenna assembly 200, and the touch sensors 300 are configured in a one-to-one correspondence with the antenna stubs, with each touch sensor 300 used to detect touch actions near the corresponding antenna stub.

[0223] In some examples, the number of touch sensors 300 is not equal to the number of antenna stubs of antenna assembly 200. For example, the number of touch sensors 300 is less than the number of antenna stubs of antenna assembly 200, or the number of touch sensors 300 is greater than the number of antenna stubs of antenna assembly 200. This application does not impose any special limitation on this.

[0224] In some examples, a corresponding touch sensor 300 may not be required for antenna stubs that are not easily held by the user.

[0225] In some examples, multiple touch sensors 300 can be set for a particular antenna stub that has a significant impact on communication performance. For example, they can be used for... Figure 12 The first antenna stub 201 is provided with, for example, two touch sensors 300, one of which is located near the first feed point 211 of the first antenna stub 201, and the other is located near the gap 230 between the first antenna stub 201 and the second antenna stub 202.

[0226] Figure 13 This is a schematic diagram showing the distribution of the touch sensor 300 provided in an embodiment of this application. For example... Figure 13As shown in the embodiments of this application, some antenna branches of the antenna assembly 200 may be located on the conductive frame 120a, that is, a section of the conductive frame 120a constitutes the antenna branch, and some antenna branches of the antenna assembly 200 (e.g., the remaining antenna branches) may be located on the inner wall of the insulating back cover 130a.

[0227] The touch sensor 300 can be located inside the housing with the sensing surface facing the outside of the device. Multiple touch sensors 300 are respectively set for multiple antenna branches. The multiple touch sensors 300 are sparsely distributed in different positions of the housing. Some touch sensors 300 are set near the conductive frame 120a, for example, these touch sensors 300 are set on the inner wall of the conductive frame 120a; other touch sensors 300 are set near the insulating back cover 130a, for example, these touch sensors 300 are set on the inner wall of the insulating back cover 130a.

[0228] Multiple touch sensors 300 are electrically connected to processor 400. Processor 400 controls antenna assembly 200 based on the detection signals from multiple touch sensors 300 and touch screen 110, thereby improving the accuracy and precision of antenna assembly 200 control, such as helping to achieve precise and timely antenna stub switching and / or high-precision intelligent tuning.

[0229] In some examples, the processor 400 can also recognize the user's grip gesture on the electronic device 100 based on the detection signals from the plurality of touch sensors 300 and the touchscreen 110, such as whether it is held with one hand, two hands, left hand, right hand, or horizontal or vertical grip. It can then control the antenna assembly 200 to perform antenna stub switching and / or intelligent tuning based on the recognized grip gesture, but is not limited to this. For example, it can also adjust the position of the content displayed on the touchscreen 110 based on the recognized grip gesture to facilitate user touch operations and improve the user experience.

[0230] For example, the processor 400 first identifies the user's grip gesture on the electronic device 100 based on the detection signal, and then controls the antenna assembly 200 based on the identified grip gesture. By combining the grip gesture, it is possible to determine which side of the electronic device 100 the user is gripping with greater force, and which side has higher coverage. Therefore, the antenna assembly 200 can be controlled more precisely based on the grip gesture (i.e., combined with the above information), which helps to further ensure that communication efficiency is not affected by hand grip. Furthermore, the processor 400 can also adjust the position of the content displayed on the touchscreen 110 based on the identified grip gesture to facilitate better touch interaction for the user. In other words, this application does not specifically limit the specific use of the grip gesture identified by the processor 400.

[0231] In some examples, the processor 400 is also used to acquire information associated with the user's grip gesture on the electronic device 100 based on the detection signal. The processor 400 can further control the electronic device 100 based on this associated information, such as controlling the antenna assembly 200 or controlling the content displayed on the touchscreen 110, thereby improving the user experience.

[0232] For example, the associated information may be information about the user interface (UI) associated with the grip gesture, so that the processor 400 can adjust the UI displayed on the touch screen 110 according to the information, such as adjusting the position of the controls to facilitate better touch interaction for the user.

[0233] In some examples, at least one of the multiple touch sensors 300 may not be configured for antenna stubs. For example, the at least one touch sensor 300 may be configured in an area of ​​the electronic device 100 that is frequently touched by the user's hand when the user uses the electronic device 100, so as to facilitate the processor 100 to perform accurate hand gesture recognition.

[0234] In some examples, the processor 400 uses the detection signals from the plurality of touch sensors 300 and the touchscreen 110, combined with an AI classification and recognition algorithm, to identify the user's grip position, which antenna segments are being held by the user, or to identify the user's grip gesture. This AI classification and recognition algorithm can be, for example, decision trees, support vector machines (SVM), K-nearest neighbors (KNN), or other machine learning algorithms; it can also be deep neural networks (DNN), convolutional neural networks (CNN), or other neural network algorithms; or it can be a commonly used, larger neural network model (such as Res-Net18), but is not limited to these.

[0235] Figure 14 This is a schematic diagram showing the distribution of the detection area of ​​the touch sensor 300 provided in this application embodiment. Figure 15 This is a schematic diagram of the user's grip gesture determined based on the detection signal from the touch sensor 300. For example... Figure 14 and Figure 15 As shown, the touch sensor 300 and the touch screen 110 have multiple detection areas arranged in an array along the touch plane. Figure 14 Each square in the diagram represents a detection area, and each detection area can detect the user's touch action and generate a corresponding detection signal. For example, Figure 14 A gray square containing the number "1" indicates that the detection area has detected a user's touch action. Figure 14 A white square containing the number "0" indicates that no user touch was detected in that detection area.

[0236] Touch sensor 300 and touchscreen 110 perform touch detection and generate corresponding detection signals. Processor 400 receives the detection signals from touch sensor 300 and touchscreen 110, and combines them with a preset AI classification and recognition algorithm to identify the user's grip gesture, such as... Figure 15 The hand gesture shown is a vertical grip, with the grip positioned slightly below the user's hand on the electronic device 100. In this case, the processor 400 can control the antenna assembly 200 based on the recognized grip gesture, performing functions such as antenna stub switching and / or intelligent tuning. For example, it can control the antenna assembly 200 to use an antenna stub located above the electronic device 100 that is not being held by the user for wireless communication, thereby avoiding the impact of the user's grip on antenna performance and improving the user experience. Furthermore, the processor 400 can also adjust the position of the content displayed on the touchscreen 110 (e.g., controls) based on the recognized grip gesture to facilitate touch operation and enhance the user experience.
