Description

Technical Field

[0001] This application belongs to the technical field of electronic devices, specifically relating to a balancing membrane assembly and an electronic device. Background Technology

[0002] Electronic devices often have many integrated functions, requiring the installation of air pressure balancing holes in their bodies. However, the presence of these air pressure balancing holes makes the device more susceptible to water ingress, which can lead to malfunction.

[0003] In related technologies, a balancing membrane is installed inside the air pressure balancing hole. The membrane's air-permeable but water-impermeable properties achieve overall waterproofing. However, the material properties of the balancing membrane can fail. When it fails, water can pass through the membrane and enter the interior of the electronic device. Because the balancing membrane does not have the function of detecting water ingress, it cannot provide a warning beforehand. As the electronic device is used for a longer period, more and more water enters, gradually corroding the internal components and ultimately causing the entire device to fail. Summary of the Invention

[0004] This application aims to provide a balancing membrane assembly and electronic device, which solves one of the problems in the related technology where the balancing membrane in the air pressure balancing hole does not have the function of detecting water ingress. When the balancing membrane fails, the user cannot know the water ingress situation in advance, which leads to more and more water entering and easily causes the whole machine to fail.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application propose a balancing membrane assembly for use in electronic devices. The balancing membrane assembly includes: a balancing membrane; and a detection membrane, the detection membrane including a water-absorbing membrane layer and a flexible circuit board, the water-absorbing membrane layer being stacked with the balancing membrane, the water-absorbing membrane layer being provided with a detection element, the detection element including a first probe and a second probe, the first probe and the second probe being arranged at intervals, and the detection element being electrically connected to the flexible circuit board.

[0007] In a second aspect, embodiments of this application provide an electronic device comprising: a balancing membrane assembly as described in the first aspect.

[0008] In embodiments of this application, the balancing membrane assembly is used in an electronic device; specifically, the balancing membrane assembly is located in a channel of the electronic device. The electronic device includes a controller, and the balancing membrane assembly includes a balancing membrane and a detection membrane, the detection membrane being electrically connected to the controller.

[0009] The detection membrane comprises an absorbent membrane layer and a flexible circuit board. The absorbent membrane layer is equipped with a detection element, which is electrically connected to the flexible circuit board. The detection element includes a first probe and a second probe, which are separately disposed.

[0010] It is understandable that the balancing membrane has both waterproof and breathable functions. That is, when the balancing membrane assembly is placed in the channel of the electronic device, sound waves can propagate through the balancing membrane in the channel. In addition, the balancing membrane also has the function of preventing water from flowing through the channel into the electronic device. In other words, the balancing membrane has the function of waterproofing the entire device.

[0011] When the balancing membrane fails, water flows through the balancing membrane to the detection membrane, where it is absorbed by the absorbent membrane layer. In other words, the detection membrane is designed to absorb water, reducing the amount of water entering the electronic equipment.

[0012] The detection device includes a first probe and a second probe. When water breaks through the equilibrium membrane, the internal absorbent membrane layer absorbs the water. The detection device, located on the absorbent membrane layer, detects changes in the absorbent membrane layer through the first and second probes. The more water enters, the greater the change in the detection data value of the device. The flexible circuit board transmits the detection data to the controller of the electronic device, so that the controller can determine the water ingress situation of the electronic device according to preset rules (e.g., whether water has entered and the severity of water ingress). This allows the electronic device to remind the user when water enters, enabling the user to be aware of the water ingress situation and decide whether to send the electronic device for repair or maintenance based on the degree of water ingress. This effectively avoids the failure of electronic devices due to water ingress, improves the performance of electronic devices, and helps reduce the difficulty and cost of subsequent repair and maintenance.

[0032] The following is combined with Figures 1 to 10 This application describes a balancing module and an electronic device 1 according to embodiments thereof.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 10 As shown, according to some embodiments of this application, a balance membrane assembly 10 is used in an electronic device 1. The balance membrane assembly 10 includes: a balance membrane 100; a detection membrane 200, the detection membrane 200 including a water-absorbing membrane layer 210 and a flexible circuit board 220, the water-absorbing membrane layer 210 being stacked with the balance membrane 100, the water-absorbing membrane layer 210 being provided with a detection element 230, the detection element 230 including a first probe 232 and a second probe 234, the first probe 232 and the second probe 234 being arranged at intervals, and the detection element 230 being electrically connected to the flexible circuit board 220.

[0034] In this embodiment, the balancing membrane assembly 10 is used in the electronic device 1. Specifically, the balancing membrane assembly 10 is located in channel 824 of the electronic device 1. The electronic device 1 includes a controller 830, and the balancing membrane assembly 10 includes a balancing membrane 100 and a detection membrane 200, which is electrically connected to the controller 830.

[0035] The detection membrane 200 includes an absorbent membrane layer 210 and a flexible circuit board 220. The absorbent membrane layer 210 is provided with a detection element 230, which is electrically connected to the flexible circuit board 220. The detection element 230 includes a first probe 232 and a second probe 234, which are in contact with the absorbent membrane layer 210, but are separately disposed.

[0036] It is understandable that the balancing membrane 100 has the functions of being waterproof and breathable. That is, after the balancing membrane assembly 10 is placed in the channel 824 of the electronic device 1, sound waves can be transmitted through the balancing membrane 100 in the channel 824. In addition, the balancing membrane 100 also has the function of blocking water from entering the electronic device 1 through the channel 824. That is, the balancing membrane 100 has the function of waterproofing the whole device.

[0037] When the balancing membrane 100 fails, the water flows through the balancing membrane 100 to the detection membrane 200. The water will be absorbed by the water-absorbing membrane layer 210 of the detection membrane 200. That is, the detection membrane 200 is designed to absorb water, thereby reducing the amount of water entering the electronic device 1.

[0038] The detection element 230 includes a first probe 232 and a second probe 234. When water breaks through the balance membrane 100, the internal absorbent membrane layer 210 absorbs the water. The detection element 230, located on the absorbent membrane layer 210, detects the changes in the absorbent membrane layer 210 through the first probe 232 and the second probe 234. The more water enters, the greater the change in the detection data value of the detection element 230. The flexible circuit board 220 transmits the detection data of the detection element 230 to the controller 830 of the electronic device 1, so that the controller 830 can determine the water ingress situation of the electronic device 1 according to preset rules (e.g., whether water has entered and the severity of water ingress). This allows the electronic device 1 to remind the user through the reminder element 840 after water ingress, so that the user can be informed of the water ingress situation of the electronic device 1 in a timely manner. The user can then decide whether to send the electronic device 1 for repair or maintenance based on the degree of water ingress. This can effectively prevent the electronic device 1 from failing due to water ingress, improve the performance of the electronic device 1, and help reduce the difficulty and cost of subsequent repair and maintenance of the electronic device 1.

[0039] Optionally, the absorbent membrane layer 210 may include a sponge layer, a foam layer, and a cotton cloth layer, etc., which will not be listed here. The absorbent membrane layer 210 has both water absorption properties and a certain degree of hardness, and plays a role in supporting and fixing the balance membrane 100 to ensure effective cooperation between the balance membrane assembly 10 and the channel 824 of the electronic device 1.

[0040] Optionally, the absorbent membrane layer 210 is stacked between the balancing membrane 100 and the flexible circuit board 220.

[0041] Optionally, the electronic device 1 can be a mobile terminal such as a mobile phone, a wearable device (e.g., a watch), a tablet computer, a laptop computer, a mobile computer, an augmented reality device (also known as an AR device), a virtual reality device (also known as a VR device), an in-vehicle device, a drone, and a handheld game console, etc.

[0042] In some embodiments, such as Figure 5 As shown, the absorbent membrane layer 210 has a recess 212, the detection element 230 is disposed in the recess 212, and the detection element 230 has a first probe point 232 and a second probe point 234 on the side away from the flexible circuit board 220.

[0043] In this embodiment, the structure of the absorbent membrane layer 210 is further defined. Specifically, the absorbent membrane layer 210 is provided with a recess 212, and the detection element 230 is disposed in the recess 212. The recess 212 serves to install and fix the detection element 230. That is, the recess 212 serves as a mounting carrier for the detection element 230, ensuring the mating dimensions between the detection element 230 and the flexible circuit board 220.

[0044] The detection element 230 includes a first probe 232 and a second probe 234, with the first probe 232 and the second probe 234 located on the side of the detection element 230 facing away from the flexible circuit board 220. That is, the first probe 232 and the second probe 234 are both positioned facing away from the flexible circuit board 220. This arrangement ensures sufficient contact area between the first probe 232, the second probe 234, and the absorbent film layer 210. The first probe 232 and the second probe 234 are surrounded by the recess 212, allowing the first probe 232 and the second probe 234 to detect changes in the absorbent film layer 210 promptly and effectively after it absorbs moisture. This enables the controller 830 to determine the water ingress status of the electronic device 1 based on the change in the amount of water absorbed by the absorbent film layer 210. Furthermore, this arrangement reduces the overall thickness of the detection element 230 and the absorbent film layer 210, thereby reducing the occupancy rate of the internal space of the electronic device 1.

[0045] Optionally, the detection element 230 is located within the recess 212. This arrangement ensures the uniformity and consistency of the overall thickness of the detection element 230 and the absorbent membrane layer 210.

[0046] Optionally, the side of the detection element 230 away from the bottom wall of the recess 212 is located on the same plane as the opening end of the recess 212. This arrangement prevents the detection element 230 from protruding from the opening end of the recess 212, thus avoiding the formation of gaps at the connection between the flexible circuit board 220 and the absorbent membrane layer 210.

[0047] Optionally, a portion of the detection element 230 extends out of the absorbent membrane layer 210 through the open end of the recess 212.

[0048] In some embodiments, the detection element 230 includes an impedance detection unit 236.

[0049] In this embodiment, the structure of the detection element 230 is further defined. Specifically, the detection element 230 includes an impedance detection unit 236. The impedance detection unit 236 is used to detect the change in impedance of the absorbent membrane layer 210. When the absorbent membrane layer 210 is in a dry state, the impedance between the first probe 232 and the second probe 234 of the detection element 230 is relatively large and can be considered as insulation. When the balance membrane 100 fails and water enters, the absorbent membrane layer 210 absorbs water, and the impedance changes after the absorbent membrane layer 210 absorbs water. Since both the first probe 232 and the second probe 234 of the detection element 230 are in contact with the absorbent membrane layer 210, the detection element 230 can detect the impedance change of the absorbent membrane layer 210 and transmit the detected data to the controller 830 of the electronic device 1. The controller 830 receives the impedance change data of the detection element 230 and controls the reminder element 840 to work according to the data to notify the user in a timely manner and avoid further damage to the whole machine.

[0050] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the flexible circuit board 220 has the same shape as the absorbent film layer 210.

[0051] In this embodiment, the mating structure of the flexible circuit board 220 and the absorbent membrane layer 210 is further defined such that the shape of the flexible circuit board 220 and the shape of the absorbent membrane layer 210 are the same, for example, the outer peripheral wall of the flexible circuit board 220 and the outer peripheral wall of the absorbent membrane layer 210 are arranged opposite to each other. This is to avoid the formation of protrusions at the connection between the flexible circuit board 220 and the absorbent membrane layer 210. It reduces the probability of dirt or water seeping into the balance membrane assembly 10 through the connection between the flexible circuit board 220 and the absorbent membrane layer 210, providing effective and reliable structural support for ensuring the service life of the balance membrane assembly 10.

[0052] In some embodiments, such as Figure 4 , Figure 6 and Figure 7 As shown, the flexible circuit board 220 is provided with a connection part 228, which is used for sending and receiving data.

[0053] In this embodiment, the flexible circuit board 220 is provided with a connection portion 228, which is used for electrical connection with the controller 830 to achieve data transmission. That is, the connection portion 228 serves as an interface for the flexible circuit board 220 to meet the usage requirements of electrical connection between the flexible circuit board 220 and the controller 830.

[0054] In some other embodiments, the controller 830 is disposed on the flexible circuit board 220. That is, the controller 830 is directly disposed on the flexible circuit board 220 without the need for an interface such as the connection part 228 to achieve electrical connection between the controller 830 and the flexible circuit board 220.

[0055] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 10 As shown, the detection membrane 200 is provided with a plurality of through holes 240, which are arranged at intervals. Each through hole 240 penetrates the absorbent membrane layer 210 and the flexible circuit board 220 in the thickness direction of the detection membrane 200.

[0056] In this embodiment, the structure of the detection membrane 200 is further defined. Specifically, the detection membrane 200 is provided with a plurality of through holes 240, and each through hole 240 penetrates the absorbent membrane layer 210 and the flexible circuit board 220 along the thickness direction of the detection membrane 200. This arrangement is more conducive to sound wave transmission, does not block sound wave transmission, can meet the ventilation requirements of the balanced membrane assembly 10, and provides structural support for ensuring the functionality of the electronic device 1.

[0057] In addition, there are multiple through holes 240, and the multiple through holes 240 are arranged at intervals. This arrangement can ensure the air passage area of ​​the detection membrane 200 and provide structural support for ensuring the air permeability and water impermeability performance of the balanced membrane module 10.

[0058] In some embodiments, such as Figure 7 As shown, the detection element 230 is located between the plurality of through holes 240 and the connecting portion 228.

[0059] In this embodiment, the mating structure of the detection element 230, the plurality of through holes 240, and the connecting portion 228 is further defined such that the detection element 230 is located between the plurality of through holes 240 and the connecting portion 228, that is, the detection element 230 is located on one side of the plurality of through holes 240. This arrangement does not obstruct the transmission of sound waves and also ensures the effectiveness of the detection element 230 in detecting changes in the absorbent membrane layer 210.

[0060] In addition, this setting also reduces the distance between the detection element 230 and the connecting part 228, which can reduce the length of the connecting line 226 used to connect the detection element 230 and the connecting part 228, thereby simplifying the routing difficulty of the connecting line 226, reducing the amount of connecting line 226 used, and thus reducing the production cost of the balance membrane module 10.

[0061] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the balancing membrane 100 is provided with a waterproof and breathable area 110, and multiple through holes 240 are arranged opposite to the waterproof and breathable area 110. The balancing membrane assembly 10 also includes: a first pad 300; a second pad 400, with the balancing membrane 100 stacked between the first pad 300 and the second pad 400; and a third pad 500, which is stacked on the side of the detection membrane 200 away from the second pad 400. The first pad 300, the second pad 400 and the third pad 500 are all provided with clearance openings 600, which are arranged opposite to the waterproof and breathable area 110.

[0062] In this embodiment, the balancing membrane assembly 10 further includes a first pad 300, a second pad 400, and a third pad 500. The balancing membrane 100 is stacked between the first pad 300 and the second pad 400, and the third pad 500 is stacked on the side of the detection membrane 200 facing away from the second pad 400. That is, along the thickness direction of the balancing membrane assembly 10, the balancing membrane assembly 10 includes the first pad 300, the balancing membrane 100, the second pad 400, the detection membrane 200, and the third pad 500. The first pad 300, the second pad 400, and the third pad 500 serve to secure the balancing membrane 100 and the detection membrane 200. Furthermore, the first pad 300, the second pad 400, and the third pad 500 also have a waterproof function, preventing water from entering the gaps between the balancing membrane 100 and the detection membrane 200.

[0063] In addition, the first pad 300, the second pad 400, and the third pad 500 are all provided with clearance openings 600. That is, the first pad 300 is provided with clearance openings 600, the second pad 400 is provided with clearance openings 600, and the third pad 500 is provided with clearance openings 600. The clearance openings 600 are arranged opposite to the waterproof and breathable area 110, that is, the clearance openings 600 are arranged corresponding to the multiple through holes 240 and the waterproof and breathable area 110. The clearance openings 600 do not obstruct the airflow, which can meet the ventilation requirements of the balance membrane module 10, and this arrangement can also ensure the structural strength of the balance membrane module 10.

[0064] In some embodiments, such as Figure 4 and Figure 6As shown, the flexible circuit board 220 is provided with a first pad 222, a second pad 224 and a connecting line 226. The first pad 222 and the first probe 232 are electrically connected, the second pad 224 and the second probe 234 are electrically connected, and the first pad 222 and the second pad 224 are both electrically connected to the connecting part 228 through the connecting line 226.

[0065] In this embodiment, the flexible circuit board 220 is provided with a first pad 222, a second pad 224 and a connecting line 226.

[0066] The first pad 222 and the first probe 232 are electrically connected. The connecting line 226 is connected to the first pad 222 and the connecting part 228 to meet the usage requirements of the first pad 222 and the connecting part 228 being electrically connected.

[0067] The second pad 224 and the second probe 234 are electrically connected. The connecting line 226 is connected to the second pad 224 and to the connecting part 228 to meet the usage requirements of the electrical connection between the second pad 224 and the connecting part 228.

[0068] This setup enables data transmission between the balance membrane module 10 and the controller 830.

[0069] like Figure 9 As shown, in some other embodiments of this application, an electronic device 1 is provided, including: a balancing membrane assembly 10 as described in any of the above embodiments.

[0070] The electronic device 1 provided by the present invention includes the balance membrane group 10 as described in any of the above embodiments, and therefore has all the beneficial effects of the balance membrane group 10, which will not be described one by one here.

[0071] In some embodiments, such as Figure 8 and Figure 9 As shown, the electronic device 1 further includes: a device body 80, which includes a frame 810 and a mounting component 820. The mounting component 820 is detachably mounted on the frame 810. The mounting component 820 has an air port 822 and a channel 824. The channel 824 is connected to the air port 822. The balancing membrane assembly 10 is located in the channel 824, and the balancing membrane 100 is closer to the air port 822 than the detection membrane 200. The controller 830 is electrically connected to the flexible circuit board 220.

[0072] In this embodiment, the electronic device 1 also includes a device body 80 and a controller 830, the controller 830 being electrically connected to the flexible circuit board 220.

[0073] The equipment body 80 includes a frame 810 and mounting components 820.

[0074] The mounting component 820 has an air inlet 822 and a channel 824, with the channel 824 communicating with the air inlet 822. The balancing membrane assembly 10 is located in the channel 824. The mounting component 820 serves as the mounting carrier for the balancing membrane assembly 10, and has the function of installing and fixing the balancing module. Among them, the balancing membrane 100 is closer to the air inlet 822 than the detection membrane 200, that is, the airflow in the environment flows from the balancing membrane 100 to the detection membrane 200.

[0075] The mounting component 820 is detachably mounted on the frame 810. This mounting configuration ensures the reliability of the connection between the mounting component 820 and the frame 810 while facilitating cleaning and maintenance of both components. Specifically, the mounting component 820 can be separated from the frame 810 or assembled together with it as needed. This configuration simplifies the assembly structure of the electronic device 1, simplifies the disassembly and assembly process, reduces the difficulty of disassembling and assembling the electronic device 1, and facilitates the repair and maintenance of the balance membrane module 10.

[0076] Understandably, when the balancing membrane module 10 is damaged, the mounting component 820 can be separated from the frame 810 to replace it with a new balancing membrane module 10, and then the balancing membrane module 10 and the mounting component 820 can be assembled back onto the frame 810. In other words, the balancing membrane module 10 can be modularly designed, allowing for rapid replacement of the balancing membrane module 10 when water ingress is detected in the electronic device 1, greatly reducing maintenance difficulty and cost.

[0077] Optionally, the flexible circuit board 220 can be bent, for example, by increasing the length of the flexible circuit board 220. In this way, when the balancing membrane 100 and / or the detection membrane 200 are damaged, the flexible circuit board 220 can be stretched to pull the balancing membrane 100 and the absorbent membrane layer 210 out of the device body 80 while ensuring that the flexible circuit board 220 is electrically connected to the controller 830. This allows the balancing membrane 100 and the absorbent membrane layer 210 to be replaced without replacing the flexible circuit board 220. This helps to reduce the cost of replacing the balancing membrane assembly 10 and also helps to reduce the difficulty of replacing the balancing membrane assembly 10.

[0078] Optionally, the electronic device 1 also includes a seal, which is located at the connection between the frame 810 and the mounting member 820 to ensure the airtightness of the electronic device 1 at the connection between the frame 810 and the mounting member 820.

[0079] Optionally, the electronic device 1 also includes fasteners, and the frame 810 and the mounting component 820 are detachably connected by fasteners, wherein the fasteners include bolts, screws, or rivets. Of course, the connection methods between the frame 810 and the mounting component 820 also include: screw connection, riveting, and plug connection, etc., which will not be listed here.

[0080] In some embodiments, such as Figure 9As shown, the device body 80 also includes a reminder component 840, which is disposed on the frame 810. The reminder component 840 is electrically connected to the controller 830, and the controller 830 is used to control the reminder component 840 to work according to the detection data of the detection component 230.

[0081] In this embodiment, the device body 80 also includes a reminder component 840, which is disposed on the frame 810. The frame 810 has the function of installing and fixing the reminder component 840. The reminder component 840 is electrically connected to the controller 830 and can transmit data with the controller 830.

[0082] Optionally, the controller 830 receives detection data from the detection element 230 and determines the water ingress status of the electronic device 1 based on the detection data (e.g., whether water has entered and the severity of water ingress). This allows the electronic device 1 to alert the user via the reminder element 840 after water ingress, enabling the user to promptly understand the water ingress status of the electronic device 1 and decide whether to send the electronic device 1 for repair or maintenance based on the degree of water ingress. This effectively avoids the failure of the electronic device 1 due to water ingress, improves the performance of the electronic device 1, and helps reduce the difficulty and cost of subsequent repair and maintenance of the electronic device 1.

[0083] Optionally, the reminder device 840 may include a speaker, a buzzer, etc., which will not be listed here.

[0084] In some embodiments, such as Figure 4 , Figure 6 , Figure 7 and Figure 9 As shown, the controller 830 is located on the frame 810 and is electrically connected to the connection part 228 of the balance diaphragm assembly 10; or the controller 830 is located on the flexible circuit board 220.

[0085] In this embodiment, the controller 830 is mounted on the frame 810, and the controller 830 is electrically connected to the connection portion 228 of the balancing membrane assembly 10. The frame 810 serves as the mounting carrier for the controller 830, and has the function of mounting and fixing the controller 830. The connection portion 228 is used for electrical connection with the controller 830 to achieve data transmission. That is, the connection portion 228 serves as the interface of the flexible circuit board 220 to meet the usage requirements of electrical connection between the flexible circuit board 220 and the controller 830.

[0086] Alternatively, the controller 830 may be located on the flexible circuit board 220, that is, the controller 830 may be directly located on the flexible circuit board 220 without the need for an interface such as the connection part 228 to achieve electrical connection between the controller 830 and the flexible circuit board 220.

[0087] like Figure 1 and Figure 3 As shown, the balancing membrane assembly 10 includes a first cushion layer 300, a balancing membrane 100, a second cushion layer 400, a detection membrane 200, and a third cushion layer 500.

[0088] The first padding layer 300, the second padding layer 400, and the third padding layer 500 serve to secure the balance membrane 100 and the detection membrane 200 around their perimeter. The first padding layer 300, the second padding layer 400, and the third padding layer 500 also have a waterproof function.

[0089] The balancing membrane 100 has the properties of being breathable but impermeable to water, such as including a polytetrafluoroethylene membrane. The detection membrane 200 provides support for the balancing membrane 100.

[0090] The balancing membrane 100 is located on the outer side, and the detection membrane 200 is located on the inner side.

[0091] The detection membrane 200 (e.g., a honeycomb membrane) includes an absorbent membrane layer 210 and a flexible circuit board 220. The absorbent membrane layer 210 is equipped with a detection element 230, which includes an impedance detection section 236. When water penetrates the balance membrane 100, the inner detection membrane 200 absorbs the water, and its built-in detection element 230 detects the impedance change of the absorbent membrane layer 210. The more water enters, the greater the impedance change. The signal from the detection element 230 is transmitted back to the controller 830, such as a CPU (Central Processing Unit). The CPU determines the severity of the water ingress according to preset rules and transmits the data to the user interface of the electronic device 1, informing the user that the electronic device 1 has been flooded. The user can repair the balance membrane assembly 10 promptly according to the degree of water ingress, thus avoiding serious damage that could lead to complete machine failure.

[0092] The detection element 230 is placed in the recess 212 of the absorbent membrane layer 210. The detection element 230 includes a first probe 232 and a second probe 234. The first probe 232 and the second probe 234 are in contact with the absorbent membrane layer 210.

[0093] A detection element 230 is embedded within the absorbent membrane layer 210. One of the first probe 232 and the second probe 234 includes a positive electrode metal, and the other of the first probe 232 and the second probe 234 includes a negative electrode metal. The detection element 230 is electrically connected to the controller 830 via a connecting wire 226.

[0094] When the honeycomb membrane is dry, the impedance between the first probe 232 and the second probe 234 of the detection element 230 is relatively high, and can be considered as insulation. When the balance membrane 100 fails and water enters, the honeycomb membrane absorbs water, and its impedance changes after water absorption. Because the first probe 232 and the second probe 234 of the detection element 230 are in contact with the honeycomb membrane, the impedance change can be detected, and the data is transmitted to the controller 830 of the electronic device 1. Upon receiving the impedance change data from the detection element 230, the controller 830 outputs a message to the user indicating that the electronic device 1 has been flooded with water. This timely notification to the user prevents further damage to the entire device.

[0095] The FPC (Flexible Printed Circuit, 220) has a first pad 222, a second pad 224, a connecting line 226, and a connection portion 228. The test component 230 is soldered onto the FPC using SMT (Surface Mount Technology).

[0096] The flexible circuit board 220 has the same shape as the absorbent film layer 210. The through-hole 240 has shapes including round holes, square holes, or oblong holes, etc., which will not be listed here.

[0097] In this embodiment, the number of detection elements 230 is one.

[0098] In some other embodiments, the number of detection elements 230 is multiple, such as two, three, four, etc., which will not be listed here.

[0099] The absorbent membrane layer 210 of the detection membrane 200 has a recess 212. The FPC with the detection element 230 attached is then bonded to the absorbent membrane layer 210.

[0100] The connector 228 is electrically connected to the controller 830 of the electronic device 1. The impedance change data of the detection element 230 is transmitted to the controller 830, which processes the impedance data.

[0101] The electronic device 1 of this application can detect the water breach in the balance pore membrane immediately, promptly reminding the user and preventing subsequent functional failure.

[0102] Electronic device 1 includes a device body 80, which includes a frame 810 and a mounting component 820. The balancing membrane module 10 is disposed in the channel 824 of the mounting component 820. The frame 810 and the mounting component 820 are detachably connected. After water ingress is detected, the balancing membrane module 10 can be quickly replaced, greatly reducing maintenance difficulty and cost.
