Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of terminals, and particularly to a pressure-sensitive touch component and an electronic device. Background Art

[0002] At present, electronic devices such as computers and mobile phones have become inseparable from our lives. They can be seen everywhere in life and have greatly improved people's living standards.

[0003] Taking a notebook computer as an example, in the related art, a pressure-sensitive touch component is usually provided on one side of the main body of the notebook computer. The pressure-sensitive touch component includes a circuit board and a pressure sensor. The pressure sensor is electrically connected to the circuit board. A glass cover plate is also covered above the circuit board and the pressure sensor. The notebook computer senses the position and movement of the user's finger through the touch module in the pressure-sensitive touch component, and controls the movement of the pointer on the display interface. The pressure sensor detects the user's pressing action, and at the same time, a vibration feedback is provided through a vibration unit to implement related key functions. The pressure-sensitive touch component can adjust the response strength to the user's pressing action and the vibration feedback intensity according to the user's usage habits, providing a more convenient and comfortable operation experience for the user.

[0004] However, in the above solution, the feel performance of the pressure-sensitive touch component is average, affecting the feel of using the notebook computer. Summary of the Invention

[0005] The present application provides a pressure-sensitive touch component and an electronic device, which can improve the pressing feel of the pressure-sensitive touch component, thereby ensuring the user experience.

[0006] In a first aspect, the embodiments of the present application provide a pressure-sensitive touch component, which at least includes: a circuit board, a reinforcing board, and at least four pressure sensors; the circuit board and the reinforcing board are stacked; at least one first opening is provided on the reinforcing board, the pressure sensor is disposed in the first opening, and the pressure sensor is electrically connected to the surface of the circuit board facing the reinforcing board.

[0007] For the pressure-sensitive touch component provided by the embodiments of the present application, by providing a reinforcing board stacked with the circuit board, the reinforcing board can ensure the structural strength and flatness of the pressure-sensitive touch component. By electrically connecting the pressure sensor to the circuit board, the electrical performance of the pressure sensor can be ensured. By providing a first opening on the reinforcing board and disposing the pressure sensor in the first opening, it is possible to avoid the stacking of the pressure sensor and the reinforcing board in the thickness direction of the pressure-sensitive touch component, thereby avoiding increasing the overall thickness of the pressure-sensitive touch component.

[0008] In addition, the pressure sensor is located in the first opening on the reinforcement plate, forming a mutually avoiding position relationship with the reinforcement plate, which can prevent the reinforcement plate from interfering with the performance of the pressure sensor when the user presses the pressure sensor. Moreover, by adjusting the shape of the reinforcement plate, it helps to compensate for the differences in travel at different positions and improve the feel of the electronic device, thereby ensuring the user experience.

[0009] In one possible implementation, the at least one first opening is located around the reinforcement plate. By providing the at least one first opening around the reinforcement plate, the strength of the surrounding area of the pressure-sensitive touch component can be weakened, which helps achieve a better vibration effect.

[0010] In one possible implementation, the at least one first opening is located in the four corners of the reinforcement plate. By placing the at least one first opening in the four corners of the reinforcement plate, the strength of the pressure-sensitive touch component in these corners can be reduced, thereby achieving a better vibration effect.

[0011] In a possible implementation, an elastic member is provided on a surface of each pressure sensor facing away from the circuit board.

[0012] By arranging an elastic member on the side of the pressure sensor facing away from the circuit board, the elastic member can optimize the vibration feeling of the pressure-sensitive touch component when it is pressed.

[0013] In a possible implementation, the elastic member is a silicone pad.

[0014] In a possible implementation, the pressure sensor and the elastic member located in the same first opening have a sum of thicknesses greater than a thickness of the reinforcing plate.

[0015] For the pressure sensor and elastic member within the same first opening, the combined thickness of the pressure sensor and elastic member is greater than the thickness of the reinforcing plate. This prevents the pressure sensor and elastic member from being relatively sunken into the reinforcing plate when they are stacked together. If the pressure sensor and elastic member were relatively sunken into the reinforcing plate when they are stacked together, the reinforcing plate would interfere with the performance of the pressure sensor.

[0016] In a possible implementation, at least one second opening is further provided on the reinforcing plate; the second opening is used to accommodate electronic components, and the electronic components are electrically connected to a side of the circuit board facing the reinforcing plate; and the second opening and the first opening avoid each other.

[0017] By providing at least one second opening on the reinforcing plate, it is also possible to provide accommodation space for other electronic components in the electronic device, thereby more effectively utilizing the space in the pressure-sensitive touch assembly and reserving more usable space for the electronic device.

[0018] By electrically connecting the electronic components to the circuit board, the electrical performance of the electronic components can be ensured. In addition, the second opening and the first opening avoid each other, which can avoid interference between the opening position of the second opening and the opening position of the first opening.

[0019] In a possible implementation, at least one of the electronic components is a vibration module, and the vibration module is used to provide vibration feedback for the pressure-sensitive touch component.

[0020] By arranging a vibration module in the second opening and electrically connecting the vibration module to the circuit board, the vibration module can provide vibration feedback for the pressing scenario of the pressure-sensitive touch component.

[0021] In a possible implementation manner, the reinforcement plate and the circuit board are fixedly connected via a first adhesive layer.

[0022] The reinforcing plate and the circuit board are fixedly connected via the first adhesive layer, which can ensure the connection reliability between the reinforcing plate and the circuit board and prevent the reinforcing plate and the circuit board from being separated from each other.

[0023] In a possible implementation, the circuit board further includes an appearance component, wherein the appearance component is stacked on a side of the circuit board facing away from the reinforcement plate.

[0024] By arranging the appearance part on the side of the circuit board away from the reinforcement plate, the appearance part can protect the circuit board, preventing external dust or objects from contaminating or scratching the circuit board and affecting the performance of the circuit board. Moreover, the appearance part can also play an aesthetic role.

[0025] In a possible implementation manner, the appearance component and the circuit board are fixedly connected via a second adhesive layer.

[0026] The appearance component and the circuit board are fixedly connected via the second adhesive layer, which can ensure the connection reliability between the appearance component and the circuit board and prevent the appearance component and the circuit board from being separated from each other.

[0027] In a possible implementation, the appearance part is made of Mylar.

[0028] Mylar has an insulating effect. Common materials include polycarbonate (PC) and polyethylene terephthalate (PET). It is used for the surface protection of membrane switches or electronic and electrical products, or for local insulation. Mylar has high insulation strength, high withstand voltage, resistance to moisture, gases, high heat, and chemical substances, low shrinkage rate, is not easily embrittled, and is wear-resistant. It is widely used in electrical insulation, PCB circuit board insulation, protection, etc.

[0029] In a possible implementation, the material used for the appearance part is polycarbonate (PC).

[0030] Or, the material used for the appearance part is polyethylene terephthalate (PET).

[0031] Polycarbonate has excellent properties such as high strength and elastic modulus, high impact strength, wide use temperature range, high transparency and free dyeability, low molding shrinkage rate, good dimensional stability, good fatigue resistance, good weather resistance, and excellent electrical properties.

[0032] Polyethylene terephthalate has excellent properties such as high tensile strength, small creep, extremely good fatigue resistance, good wear resistance, good friction resistance, little influence of mechanical properties by temperature, good heat aging resistance, and excellent electrical insulation.

[0033] In a possible implementation, the thickness of the appearance part is 0.2mm - 0.3mm.

[0034] In a possible implementation, the thickness of the appearance part is 0.25mm.

[0035] In a second aspect, an embodiment of the present application provides an electronic device, which at least includes: a main body of the host; an installation opening is provided on the main body of the host, and any one of the above-mentioned pressure-sensitive touch control components is provided in the installation opening.

[0036] The electronic device provided by the embodiment of the present application includes a pressure-sensitive touch control component. By arranging a reinforcing plate laminated with the circuit board, the reinforcing plate can ensure the structural strength and flatness of the pressure-sensitive touch control component. Electrically connected to the circuit board through a pressure sensor, it can ensure the electrical performance of the pressure sensor. By providing a first opening on the reinforcing plate and arranging the pressure sensor in the first opening, it can avoid the stacking of the pressure sensor and the reinforcing plate in the thickness direction of the pressure-sensitive touch control component, and thus can avoid increasing the overall thickness of the pressure-sensitive touch control component.

[0037] In addition, the pressure sensor is located within the first opening on the reinforcing plate, forming a position relationship of mutual avoidance with the reinforcing plate, which can prevent the reinforcing plate from interfering with the performance of the pressure sensor when the user presses the pressure sensor. Moreover, by adjusting the shape of the reinforcing plate, it helps to compensate for the stroke differences at different positions and improve the tactile feel of the electronic device, thus ensuring the user experience.

[0050] The terms used in the embodiments section of the present application are only for explaining the specific embodiments of the present application and are not intended to limit the present application. The following will describe the embodiments of the present application in detail with reference to the drawings.

[0051] Embodiments of the present application provide an electronic device, which may include, but is not limited to, a desktop computer, a tablet computer (Table), a laptop computer (Laptop), an ultra-mobile personal computer (UMPC), a handheld computer, a walkie-talkie, a netbook, a point of sales (POS) machine, a personal digital assistant (PDA), a television, a projector, a cloud terminal, a wearable device, a virtual reality device, or a mobile terminal such as an in-vehicle pre-installed device or a security device, a fixed terminal, or a foldable device.

[0052] In the embodiments of the present application, a laptop computer is taken as an example of the above-mentioned electronic device for illustration.

[0053] Figure 1 A three-dimensional structural schematic diagram of the laptop computer is shown. Refer to Figure 1 As shown, the electronic device 200 may include: a display screen 210 and a main body 220 of the host. Among them, the display screen 210 may be used to display images, videos, etc., and the main body 220 of the host may be used to input instructions and data, and control the display screen 210 to display images and videos according to the input instructions and data. At the same time, the main body 220 of the host may also be used to play voice or music.

[0054] The electronic device 200 can be switched between an open state and a closed state. When the electronic device 200 is in the open state, the display screen 210 and the main body 220 of the host form an angle greater than 0° and less than 360°. That is to say, the display screen 210 can rotate 360° around the main body 220 of the host. When the electronic device 200 is in the closed state, the display screen 210 covers the main body 220 of the host, and the display surface of the display screen 210 faces the keyboard surface of the main body 220 of the host.

[0055] Specifically, the display screen 210 and the main body 220 of the host may be rotatably connected. For example, the display screen 210 and the main body 220 of the host may be connected by a rotating shaft. Or, the display screen 210 and the main body 220 of the host may be rotatably connected by a hinge structure. Or, in some examples, the display screen 210 and the main body 220 of the host may be independent devices. For example, the display screen 210 and the main body 220 of the host are detachable. When in use, the display screen 210 is placed on the main body 220 of the host. After use, the display screen 210 and the main body 220 of the host can be separated from each other.

[0056] It should be noted that in order to achieve the display effect of the display screen 210, an electrical connection is required between the display screen 210 and the main body 220 of the host. For example, the electrical connection between the display screen 210 and the main body 220 of the host can be achieved through contacts, or the electrical connection between the display screen 210 and the main body 220 of the host can be achieved through a flexible printed circuit (FPC), or the electrical connection between the display screen 210 and the main body 220 of the host can be achieved through wires. In addition, the display screen 210 and the main body 220 of the host can also be wirelessly connected through a wireless signal (such as a Bluetooth signal).

[0057] It should be noted that when the display screen 210 is a flat screen, the display screen 210 can be an organic light-emitting diode (OLED) display screen 210, or a liquid crystal display (LCD) screen 210. When the display screen 210 is a curved screen, the display screen 210 can be an OLED display screen 210.

[0058] See Figure 1 As shown, in order to achieve the input of the electronic device 200, the electronic device 200 may further include: a keyboard device 230, which is used to input instructions and data. The keyboard device 230 can be provided on the main body 220 of the host. For example, the main body 220 of the host may have a mounting portion (not shown in the figure), and the keyboard device 230 is assembled and provided on the mounting portion of the main body 220 of the host. The keyboard device 230 is electrically connected to the control unit in the main body 220 of the host, and the keyboard device 230 serves as an input device of the electronic device 200.

[0059] In some other embodiments, it can also be to input characters or operation instructions through a button-type touch keyboard, or to control the cursor movement or perform multi-gesture operations through a touch method. Specifically, the display screen 210 and the button-type touch keyboard can be placed at a predetermined distance from each other and used, and the display screen 210 and the button-type touch keyboard can be wirelessly connected through a wireless signal (such as a Bluetooth signal), so that the user can arbitrarily adjust the placement position of the button-type touch keyboard according to personal usage habits. Among them, in the embodiments of the present application, the button-type touch keyboard can be, for example, a wireless keyboard.

[0060] It can be understood that the display screen 210 and the button-type touch keyboard can be interconnected through a communication network to achieve the interaction of wireless signals. The communication network can be, but is not limited to, short-range communication networks such as WI-FI hotspot network, WI-FI peer-to-peer (P2P) network, Bluetooth network, zigbee network, or near field communication (NFC) network. The button-type touch keyboard 10 can provide input to the electronic device 200, and the electronic device 200 performs an operation in response to the input based on the input of the button-type touch keyboard.

[0061] The keyboard device 230 may include: a keyboard substrate (not shown in the figure) and a plurality of keys 231 provided on the keyboard substrate. The types of the keys 231 can refer to Figure 1 the structure. For example, the plurality of keys 231 include numeric keys 231, function keys 231 (such as Delete keys 231, Insert keys 231, etc.), and alphabet keys 231, etc. According to the size of the keys 231, they can be divided into single-sized keys 231 and multi-sized keys 231. The single-sized keys 231 are the square keys above the keyboard (the structure on the upper surface of the keyboard is similar to a square), such as the keys 231 corresponding to each letter and each number. The multi-sized keys 231 are the keys 231 other than the single-sized keys 231. The multi-sized keys 231 can be strip-shaped. For example, the length of the multi-sized keys 231 is greater than the width.

[0062] See Figure 1 As shown, some keys 231, such as the single-sized keys 231, are smaller in size. For example, in a keyboard device 230 of the present application, the length and width of the single-sized keys 231 are both 1.6 cm. Some keys 231, such as the multi-sized keys 231 (such as: space keys 231, Enter keys 231, and Shift keys 231, etc.), are larger in size than the single-sized keys 231. For example, in a keyboard device 230 of the present application, the length and width of some multi-sized keys 231 are 1.8 cm and 1.6 cm respectively, and the length and width of some multi-sized keys 231 are 10.2 cm and 1.6 cm respectively, etc.

[0063] Among them, in order to implement the input function of the keys 231, contacts (not shown in the figure) can be provided on the keyboard substrate. After the keys 231 are pressed, the contacts are triggered to achieve the input function.

[0064] Among them, in order to implement the shooting function, the electronic device 200 may further include: a camera module. Continuing to refer to Figure 1As shown, the camera module may include a front camera module 240 and a rear camera module (not shown in the figure). Among them, the rear camera module may be disposed on a surface of the display screen 210 facing away from the main body 220 of the host. An opening is provided on the display screen 210, and the lens of the rear camera module corresponds to the opening. Installation holes (not shown in the figure) for installing a partial area of the rear camera module may be provided on the display screen 210.

[0065] Taking the electronic device 200 in the closed state as an example, the front camera module 240 may be disposed on a surface of the display screen 210 facing the main body 220 of the host, or the front camera module 240 may be disposed on a surface of the display screen 210 facing away from the main body 220 of the host. An opening for exposing the lens end of the front camera module 240 is provided on the display screen 210.

[0066] In the embodiments of the present application, the installation positions of the front camera module 240 and the rear camera module may include but are not limited to the above description. Among them, in some embodiments, the number of the front camera module 240 and the rear camera module provided in the electronic device 200 may be 1 or N, and N is a positive integer greater than 1.

[0067] In order to control the movement of the pointer on the display interface of the display screen 210, an installation opening 221 may be provided on the main body 220 of the host. A pressure sensing component may be disposed in the installation opening 221. In the related art, the pressure sensing component includes a circuit board and a touch sensor. The touch sensor is electrically connected to the circuit board. A glass cover plate is further covered above the circuit board and the touch sensor. The notebook computer senses the position and movement of the user's finger through the touch sensor and controls the movement of the pointer on the display interface. However, in the prior art, the pressing feel of the pressure sensing component is poor, which easily affects the use feel of the notebook computer.

[0068] Based on this, the embodiments of the present application provide a pressure sensing component and an electronic device having the pressure sensing component. The pressure sensing component at least includes: a circuit board, a reinforcing plate, and at least four pressure sensors; the circuit board and the reinforcing plate are stacked; at least one first opening is provided on the reinforcing plate, the pressure sensors are disposed in the first opening, and the pressure sensors are electrically connected to a surface of the circuit board facing the reinforcing plate. In this way, the difference in stroke at different positions can be compensated, the use feel of the electronic device can be improved, and thus the use performance of the electronic device can be improved to ensure the user experience.

[0069] Next, taking specific embodiments as examples, the specific structure of the pressure sensing component will be introduced in conjunction with the drawings.

[0070] Refer to Figure 2 and Figure 3As shown in the figure, an embodiment of the present application provides a pressure sensing component 100, which may at least include: a circuit board 110, a reinforcing plate 120, and at least four pressure sensors 130. Among them, the circuit board 110 and the reinforcing plate 120 are stacked, and at least one first opening 121 may be provided on the reinforcing plate 120. At least four pressure sensors 130 may be disposed in at least one first opening 121. Moreover, the pressure sensor 130 may be electrically connected to the surface of the circuit board 110 facing the reinforcing plate 120 (i.e., the first surface 111 of the circuit board).

[0071] In an embodiment of the present application, at least one first opening 121 may be located around the reinforcing plate 120. By arranging at least one first opening 121 around the reinforcing plate 120, the strength of the peripheral area of the pressure sensing component 100 can be made weaker, which helps to achieve a better vibration effect.

[0072] The number of pressure sensors 130 may be four, five, six, seven, eight or more, and the embodiments of the present application do not limit this. Among them, taking the number of pressure sensors 130 as four as an example, exemplarily, Figure 2 in the figure, the reinforcing plate 120 is provided with four first openings 121, and each first opening 121 is provided with a pressure sensor 130.

[0073] Specifically, as Figure 2 shown in the figure, in an embodiment of the present application, at least one first opening 121 may be located in the four corner areas of the reinforcing plate 120. By arranging at least one first opening 121 in the four corner areas of the reinforcing plate 120, the strength of the four corner areas of the pressure sensing component 100 can be made weaker, which helps to achieve a better vibration effect.

[0074] Alternatively, in some other examples, it may also be that only one first opening 121 is provided on the reinforcing plate 120, and all four pressure sensors 130 are located in this first opening 121. At this time, the first opening 121 may be an annular opening. Or, it may also be that only two first openings 121 are provided on the reinforcing plate 120, and each first opening 121 is provided with two pressure sensors 130. At this time, the first opening 121 may be a strip-shaped opening. Of course, the embodiments of the present application may also include other layout methods, which are not limited here.

[0075] In the embodiments of the present application, the circuit board 110 may be a printed circuit board assembly (PCBA), that is, a printed circuit board (PCB) blank board is loaded with components through surface mount technology (SMT) or dual inline-pin package (DIP) plug-in components. That is to say, the PCBA is a board formed by the entire process of loading components onto the PCB blank board through SMT or through DIP plug-in components.

[0076] By providing a reinforcing plate 120 laminated with the circuit board 110, the reinforcing plate 120 can ensure the structural strength and flatness of the pressure sensing touch control component 100.

[0077] The pressure sensor 130 may be a resistive pressure sensor, also known as a piezoresistive pressure sensor. Alternatively, the pressure sensor 130 may also be a piezoelectric ceramic pressure sensor or a capacitive pressure sensor. The embodiments of the present application do not limit this, nor are they limited to the above examples.

[0078] Specifically, in some embodiments, the pressure sensor 130 may be a strain gauge. When the pressure applied by the user when pressing the pressure sensing touch control component 100 is transmitted to the strain gauge, the strain gauge deforms, thereby causing a change in the resistance value. The magnitude of the pressure can be calculated based on the change in the resistance value. By electrically connecting the pressure sensor 130 to the circuit board 110, the electrical performance of the pressure sensor 130 can be ensured.

[0079] Specifically, the electrical connection between the pressure sensor 130 and the circuit board 110 can be achieved through a soldering process. Exemplarily, the pressure sensor 130 and the circuit board 110 can be fixed with solder. Solder can be used for mechanical connection and / or electrical connection. The materials used for the solder can be tin solder, lead solder, tin-lead alloy solder, silver solder, or copper solder, etc. The shape of the solder can be spherical, polyhedral, ellipsoidal, frustum-shaped, chamfered, strip-shaped, rod-shaped, etc. The embodiments of the present application do not limit the material and shape of the solder, nor are they limited to the above examples.

[0080] It is easy to understand that in the actual soldering process, the soldering methods between the pressure sensor 130 and the circuit board 110 may include but are not limited to low-temperature soldering and laser soldering, etc.

[0081] In addition, by providing a first opening 121 on the reinforcing plate 120 and disposing the pressure sensor 130 within the first opening 121, with the reinforcing plate 120 avoiding the pressure sensor 130, it is possible to prevent the pressure sensor 130 and the reinforcing plate 120 from overlapping in the thickness direction of the pressure-sensitive touch control assembly 100, thereby avoiding an increase in the overall thickness of the pressure-sensitive touch control assembly 100.

[0082] Moreover, the pressure sensor 130 is located within the first opening 121 on the reinforcing plate 120, forming a position relationship of mutual avoidance with the reinforcing plate 120, which can prevent the reinforcing plate 120 from interfering with the performance of the pressure sensor 130 when the user presses the pressure sensor 130, can increase the pressing stroke of the pressure-sensitive touch control assembly 100, and thus can improve the user experience when using the electronic device 200, thereby ensuring the user experience when using the electronic device 200.

[0083] In an actual application scenario, different position stroke differences can be achieved by adjusting the shape of the reinforcing plate 1 twenty, realizing a stroke experience similar to that of the long and short sides.

[0084] In some scenarios, if the reinforcing plate 120 is a rectangular plate with inconsistent length and width, the pressing effect on the long side of the reinforcing plate 120 is different from that on the short side of the reinforcing plate 120. Due to the unequal stroke, the pressing stroke experience will be inconsistent. However, by adjusting the shape of the reinforcing plate 120, the stroke can also be compensated to achieve a stroke experience similar to that of the long and short sides.

[0085] In addition, as shown in Figure 3 In the embodiment of the present application, an elastic member 140 can be provided on the surface of each pressure sensor 130 facing away from the circuit board 110. By providing the elastic member 140 on the surface of the pressure sensor 130 facing away from the circuit board 110, the elastic member 140 can optimize the vibration feeling when the pressure-sensitive touch control assembly 100 is pressed.

[0086] In the embodiment of the present application, the elastic member 140 can be a silicone pad. Silicone has a certain elasticity and good support performance, which helps to optimize the vibration feeling when the pressure-sensitive touch control assembly 100 is pressed.

[0087] It can be understood that in the embodiment of the present application, the thickness of the elastic member 140 can be 0.5 mm - 0.7 mm. Exemplarily, the thickness of the elastic member 140 can be 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, or 0.7 mm, etc. The embodiment of the present application does not limit this, nor is it limited to the above examples.

[0088] The thickness of the pressure sensor 130 can be 0.4 mm - 0.5 mm. Exemplarily, the thickness of the pressure sensor 130 can be 0.4 mm, 0.41 mm, 0.42 mm, 0.43 mm, 0.44 mm, 0.45 mm, 0.46 mm, 0.47 mm, 0.48 mm, 0.49 mm, or 0.5 mm, etc. The embodiments of the present application do not limit this, nor are they limited to the above examples.

[0089] The thickness of the reinforcing plate 120 can be 0.3 mm - 1 mm. Exemplarily, the thickness of the reinforcing plate 120 can be 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, or 1 mm, etc. The embodiments of the present application do not limit this, nor are they limited to the above examples.

[0090] It can be understood that in the embodiments of the present application, for the pressure sensor 130 and the elastic member 140 located in the same first opening 121, the sum of the thicknesses of the pressure sensor 130 and the elastic member 140 can be greater than the thickness of the reinforcing plate 120.

[0091] For the pressure sensor 130 and the elastic member 140 in the same first opening 121, the sum of the thicknesses of the pressure sensor 130 and the elastic member 140 stacked together is greater than the thickness of the reinforcing plate 120, which can prevent the pressure sensor 130 and the elastic member 140 from being relatively recessed into the reinforcing plate 120 when stacked together. If the pressure sensor 130 and the elastic member 140 are relatively recessed into the reinforcing plate 120 when stacked together, the reinforcing plate 120 will interfere with the performance of the pressure sensor 130.

[0092] In addition, in the embodiments of the present application, at least one second opening 122 can be provided on the reinforcing plate 120. The second opening 122 can be used to accommodate the electronic component 150, and the electronic component 150 is electrically connected to the side of the circuit board 110 facing the reinforcing plate 120. It can be understood that by electrically connecting the electronic component 150 to the circuit board 110, the electrical performance of the electronic component 150 can be ensured.

[0093] In a possible implementation manner, at least one electronic component 150 can be a vibration module 151, and the vibration module 151 is used to provide vibration feedback for the pressure touch control component 100. Specifically, the vibration module 151 is mainly used for vibration feedback after pressure or touch perception, so that the pressure touch control component 100 can achieve the corresponding key feel.

[0094] That is to say, by arranging the vibration module 151 in the second opening 122, the vibration module 151 is electrically connected to the circuit board 110, and the vibration module 151 can provide vibration feedback for the pressing scenario of the pressure touch control component 100, improving the vibration feel of the pressure touch control component 100.

[0095] Specifically, in the embodiment of the present application, the vibration module 151 may be a linear motor, and the linear motor may be bonded to a surface of the circuit board 110 facing the reinforcement plate 120 .

[0096] In some embodiments, the electronic component 150 may also be a connector 152 or a chip. For example, in the embodiment of the present application, Figure 2 The electronic component 150 shown in the figure can be a connector 152, which is used to electrically connect the circuit board 110 to the main board in the host body 220 to achieve communication and power supply functions.

[0097] By providing at least one second opening 122 on the reinforcing plate 120 , space can be provided for other electronic components 150 in the electronic device 200 , thereby more effectively utilizing the space in the pressure-sensitive touch assembly 100 and reserving more space for use in the electronic device 200 .

[0098] Moreover, by providing the second opening 122 on the reinforcing plate 120, other electronic components 150 in the electronic device 200 are arranged in the second opening 122. The reinforcing plate 120 avoids the electronic components 150, which can prevent the electronic components 150 and the reinforcing plate 120 from stacking in the thickness direction of the pressure-sensitive touch assembly 100, thereby further avoiding an increase in the overall thickness of the pressure-sensitive touch assembly 100.

[0099] In addition, in a possible implementation, the second opening 122 and the first opening 121 may avoid each other, thereby preventing interference between the opening positions of the second opening 122 and the first opening 121.

[0100] In the embodiment of the present application, the material used for the reinforcing plate 120 can be a metal material. Specifically, the material used for the reinforcing plate 120 can be steel, aluminum, or aluminum alloy. The embodiment of the present application does not limit the specific material of the reinforcing plate 120, nor is it limited to the above examples.

[0101] It is easy to understand that in the embodiment of the present application, the pressure-sensitive touch assembly 100 may further include: an appearance component 160 , wherein the appearance component 160 may be stacked on a side of the circuit board 110 away from the reinforcement plate 120 (i.e., on the second surface 112 of the circuit board).

[0102] By providing an exterior member 160 on the side of the circuit board 110 facing away from the reinforcement board 120, the exterior member 160 can protect the circuit board 110, preventing external dust or objects from contaminating or scratching the circuit board 110 and affecting its performance. Moreover, the exterior member 160 can also enhance the aesthetics.

[0103] It can be understood that in the embodiments of the present application, the thickness of the exterior member 160 can be 0.2 mm - 0.3 mm. Exemplarily, the thickness of the exterior member 160 can be 0.2 mm, 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm, 0.25 mm, 0.26 mm, 0.27 mm, 0.28 mm, 0.29 mm, or 0.3 mm, etc. The embodiments of the present application do not limit this, nor are they limited to the above examples.

[0104] In the embodiments of the present application, the reinforcement board 120 and the circuit board 110 can be fixedly connected through a first adhesive layer 170.

[0105] The fixed connection between the reinforcement board 120 and the circuit board 110 through the first adhesive layer 170 can ensure the connection reliability between the reinforcement board 120 and the circuit board 110, preventing the reinforcement board 120 and the circuit board 110 from separating from each other.

[0106] The thickness of the first adhesive layer 170 can be 0.05 mm - 0.1 mm. Exemplarily, the thickness of the first adhesive layer 170 can be 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, or 0.1 mm, etc. The embodiments of the present application do not limit this, nor are they limited to the above examples.

[0107] In addition, the exterior member 160 and the circuit board 110 can be fixedly connected through a second adhesive layer 180.

[0108] The fixed connection between the exterior member 160 and the circuit board 110 through the second adhesive layer 180 can ensure the connection reliability between the exterior member 160 and the circuit board 110, preventing the exterior member 160 and the circuit board 110 from separating from each other.

[0109] The thickness of the second adhesive layer 180 can be 0.05 mm - 0.1 mm. Exemplarily, the thickness of the second adhesive layer 180 can be 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, or 0.1 mm, etc. The embodiments of the present application do not limit this, nor are they limited to the above examples.

[0110] The combined thickness of the appearance part 160 and the second adhesive layer 180 can be 0.25 mm - 0.4 mm. Exemplarily, the combined thickness of the appearance part 160 and the second adhesive layer 180 can be 0.25 mm, 0.3 mm, 0.35 mm, or 0.4 mm, etc. The embodiments of the present application do not limit this, nor are they limited to the above examples.

[0111] It should be noted here that the numerical values and numerical ranges involved in the present application are approximate values. Affected by the manufacturing process, there may be a certain range of errors, and those skilled in the art can consider this part of the errors to be negligible.

[0112] It should be noted that in the embodiments of the present application, the second adhesive layer 180 can be the second adhesive layer 180 or glue. The embodiments of the present application do not limit the specific material of the second adhesive layer 180, as long as it can play a bonding role.

[0113] In the embodiments of the present application, the material used for the appearance part 160 can be mylar.

[0114] Mylar mostly has an insulating function. Common materials include polycarbonate (PC) and polyethylene terephthalate (PET), which are used for surface protection of membrane switches or electronic and electrical products, or play a local insulating role. Mylar has the advantages of high insulation strength, high withstand voltage, resistance to moisture, gas, high heat, and chemical substances, low shrinkage rate, not easy to embrittle, and wear resistance, and is widely used in electrical insulation, PCB circuit board insulation, protection, etc.

[0115] Moreover, compared with the glass cover plate used for the appearance part 160 in the prior art, mylar can achieve lower material costs, and the solution using mylar is easier to achieve different appearance effects. Specifically, when the appearance part 160 is arranged in the installation opening 221 on the main body 220 of the host, if the appearance part 160 is a glass cover plate, during the production process, the glass cover plate and the housing part of the main body 220 of the host are generally produced in the same process. That is to say, the glass cover plate and the housing part of the main body 220 of the host are mutually matched and cannot be replaced.

[0116] If the housing part of the main body 220 of the host is mylar, during the production process, after the housing part of the main body 220 of the host is produced, mylar of different colors and styles can be matched. Therefore, when the material used for the appearance part 160 in the embodiments of the present application is mylar, it is easier to achieve different appearance effects.

[0117] It should be noted that in the embodiments of the present application, the material used for the appearance part 160 can include but is not limited to the following two possible implementation manners:

[0118] One possible implementation is that the material used for the appearance part 160 can be polycarbonate (PC).

[0119] Polycarbonate has excellent properties such as high strength and elastic modulus, high impact strength, wide use temperature range, high transparency and free dyeability, low molding shrinkage rate, good dimensional stability, good fatigue resistance, good weather resistance, and excellent electrical properties.

[0120] Another possible implementation is that the material used for the appearance part 160 can be polyethylene terephthalate (PET).

[0121] Polyethylene terephthalate has excellent properties such as high tensile strength, small creep, excellent fatigue resistance, good wear resistance, good friction resistance, little influence of mechanical properties by temperature, good heat aging resistance, and excellent electrical insulation.

[0122] It should be noted that in the embodiments of the present application, the appearance part 160 can be a mylar cover plate or other protective cover plates. The appearance part 160 is mainly used to provide an input surface for finger touch or pressing, and at the same time is used to protect the circuit board 110 and the pressure sensor 130 below the appearance part 160. During specific operations, the user can touch or move on the input surface provided by the appearance part 160 with a finger to control the electronic device 200 to execute instructions related to touch operations, or move the pointer on the display interface of the display screen 210 of the electronic device 200.

[0123] Moreover, when touching or moving on the appearance part 160 with a finger, the appearance part 160 can be synchronously pressed to apply a downward pressure to the pressure touch control component 100 to control the electronic device 200 to execute instructions related to pressing operations.

[0124] It should be understood that although the appearance part 160 is taken as a mylar cover plate or other protective cover plates in the embodiments of the present application, in some specific application scenarios, the appearance part 160 can also be other functional components in the electronic device 200, such as components with display functions. The embodiments of the present application do not limit this.

[0125] In addition, in order to implement the external sound playback of the electronic device 200, a speaker (not shown in the figure) may often be provided in the main body 220 of the host. The speaker is used to convert the audio electrical signal into a sound signal, so that the user can listen to the sound emitted by the electronic device 200 through an external earphone or through the built-in speaker. Among them, the design position of the speaker needs to be set according to the specific working conditions. In some embodiments of the present application, the speaker is arranged close to the outer edge of the keyboard device 230. It should be noted that when the speaker is arranged close to the outer edge of the keyboard device 230, "close" specifically means that when the speaker is arranged on the main body 220 of the host, relative to the center of the keyboard device 230 on the main body 220 of the host, the speaker is closer to the outer edge of the keyboard device 230.

[0126] Exemplarily, in the embodiments of the present application, the number of speakers may be two, symmetrically arranged on the lower edge of the keyboard device 230. Of course, the speaker may also be arranged on the upper edge or the left and right side edges of the keyboard device 230. In some other embodiments, the number of speakers may also be one or more than three, which is not specifically limited herein. In addition, the sound outlet holes (not shown in the figure) of the electronic device 200 may be arranged corresponding to the specific positions of the speakers, or opened on the left and right sides of the main body 220 of the host.

[0127] It should be understood that when the number of sound outlet holes is multiple, the multiple sound outlet holes may be evenly spaced. In this way, not only can the sound output effect and the sound quality uniformity of the sound outlet holes be enhanced, but also the appearance beauty of the electronic device 200 can be improved.

[0128] In addition, in the embodiments of the present application, a microphone, that is, a microphone, may also be provided in the electronic device 200. The microphone is used to convert the sound signal into an electrical signal. When making a call or sending a voice message, the user can make a sound close to the microphone with the mouth to input the sound signal into the microphone. In the embodiments of the present application, a sound inlet (not shown in the figure) opposite to the microphone may also be opened on the main body 220 of the host, so that external sounds can be input into the microphone through the sound inlet.

[0129] A power interface may also be opened on the main body 220 of the host between the sound outlet hole and the sound inlet. The power interface may be a USB Type-C interface, or may also be a Micro USB interface.

[0130] It should be understood that the opening positions of the sound outlet, sound inlet, and power interface may include but are not limited to the positions described above. In some other examples, the opening positions of the sound outlet, sound inlet, and power interface can be adjusted according to actual needs. Among them, in the embodiments of the present application, the electronic device 200 may be provided with at least one microphone. In some embodiments, the electronic device 200 may be provided with two microphones, which can not only collect sound signals but also implement a noise reduction function. In some other embodiments, the electronic device 200 may also be provided with three, four or more microphones to collect sound signals, reduce noise, identify the sound source, and implement functions such as directional recording.

[0131] Among them, in the embodiments of the present application, the speaker assembly and the microphone can be electrically connected to the processor on the circuit board through the audio module, so that the speaker assembly, the microphone, the audio module, and the processor can implement audio functions such as music playback and recording. The audio module can be set in the processor, or some functions of the audio module can be set in the processor. The audio module can convert digital audio information into an analog audio signal for output, and is also used to convert an analog audio input into a digital audio signal, and can also be used for encoding and decoding audio signals.

[0132] It can be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the electronic device 200. In some other embodiments of the present application, the electronic device 200 may include more or fewer components than shown in the figure, or combine certain components, or split certain components, or have different component arrangements. For example, the electronic device 200 may also include devices such as a flashlight. The illustrated components can be implemented in hardware, software, or a combination of software and hardware.
