Abstract
Description
Technical Field
[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology
[0002] Currently, mobile phones are increasingly focusing on reliability design, and waterproofing is a major direction for improving reliability. IPX9 is an internationally recognized testing standard used to evaluate the waterproof performance of electronic devices under high-pressure water jet conditions. This standard requires the device to withstand high-pressure water jets under specific pressure and distance, ensuring that the device can still function normally in humid environments.
[0003] To waterproof the microphone's sound guide channel, a waterproof and breathable membrane is usually installed inside the sound guide channel. However, due to the poor waterproof performance of the current sound guide channel, high-pressure water jets can impact the waterproof and breathable membrane during waterproofing tests, easily causing it to rupture and leading to the failure of the microphone's waterproof structure. Utility Model Content
[0004] This application aims to provide an electronic device that solves the problem of poor waterproofing of the internal structure of the sound guide channel in related technologies.
[0005] To solve the above-mentioned technical problems, this application is implemented as follows:
[0006] This application provides an electronic device, including:
[0007] The frame has a sound guide hole and a sound guide channel is provided inside the frame. The sound guide channel includes a first channel and a second channel that are connected to each other. The first channel and the second channel extend in different directions. The first end of the first channel is connected to the sound guide hole.
[0008] The microphone's sound outlet faces the second channel;
[0009] A waterproof and breathable component is connected to the frame and is located between the microphone and the second channel;
[0010] The pressure relief mesh is connected to the frame and is installed on the side of the waterproof and breathable component facing the sound channel.
[0011] In the embodiments of this application, a waterproof and breathable component is installed within the sound guide channel. This component possesses both waterproof and breathable properties, preventing water from the outside of the electronic device from penetrating it, thus providing waterproofing. A pressure relief mesh is also installed within the sound guide channel. The waterproof and breathable component is located between the microphone and the second channel. During waterproof testing, high-pressure water jets pass through the pressure relief mesh before contacting the component. The water pressure decreases as the jets pass through the mesh, reducing the likelihood of damage when the water reaches the component. This reduces the destructive force of the water jets and prevents the component from failing. Through these methods, the waterproof performance of the electronic device is improved.
[0012] In this embodiment, the sound guiding channel is located inside the frame, forming an independent sound guiding channel within the frame. Therefore, it is not necessary to create a large opening in the frame, and the sound guiding channel is formed by covering the opening with other structures. Without the need for a large opening in the frame, the frame has greater rigidity and better flatness. When the display assembly is mounted on the frame, the screen component and display driver within the display assembly are less prone to breakage, ensuring the reliability of the display assembly.

[0026] The following is combined with Figures 1-5 This application describes an electronic device according to an embodiment of the present application.
[0027] like Figure 1 As shown, according to some embodiments of this application, the electronic device 100 includes: a frame 110, a microphone 131, a waterproof and breathable component 140, and a pressure relief mesh 150. The frame 110 has a sound guide hole 116, and a sound guide channel 111 is provided within the frame 110. The sound guide channel 111 includes a first channel 113 and a second channel 114 that are interconnected. The first channel 113 and the second channel 114 have different extending directions. The first end of the first channel 113 is connected to the sound guide hole 116, and the sound outlet 135 of the microphone 131 faces the second channel 114. The waterproof and breathable component 140 is connected to the frame 110 and is disposed between the microphone 131 and the second channel 114. The pressure relief mesh 150 is connected to the frame 110 and is disposed on the side of the waterproof and breathable component 140 facing the sound guide channel 111.
[0028] A waterproof and breathable component 140 is installed inside the sound guiding channel 111. The waterproof and breathable component 140 has waterproof and breathable properties, preventing water from the outside of the electronic device 100 from passing through it, thus providing waterproofing for the electronic device 100. A pressure relief net 150 is also installed inside the sound guiding channel 111, positioned on the side of the waterproof and breathable component 140 facing the sound guiding channel 111. The sound guiding channel 111 includes a first channel 113 and a second channel 114. When water flows into the sound guiding channel 111, due to the different extension directions of the first channel 113 and the second channel 114, the water flow will change direction as it passes through them. During this change, the water flow will impact the inner wall of the sound guiding channel 111, thereby dissipating some of the water flow's kinetic energy and achieving pressure relief. The water flow is depressurized before reaching the waterproof and breathable component 140, preventing damage to the component.
[0029] During the waterproof test, the high-pressure water flow passes through the pressure relief net 150 before contacting the waterproof breathable component 140. When the high-pressure water flow passes through the pressure relief net 150, the water pressure will decrease. When the water flow reaches the waterproof breathable component 140, the lower water pressure will not easily damage the waterproof breathable component 140, thus reducing the destructive force of the water flow on the waterproof breathable component 140, thereby ensuring the waterproof breathable component 140 and preventing its failure. In this way, the waterproof performance of the electronic device 100 is improved.
[0030] In this embodiment, the sound guiding channel 111 is disposed inside the frame 110, forming an independent sound guiding channel 111 inside the frame 110. Therefore, it is not necessary to open a large opening on the frame 110, and the sound guiding channel 111 is formed by covering the opening with other structures. Since a large opening is not required on the frame 110, the frame 110 has high rigidity and good flatness. When the display assembly 120 in the electronic device 100 is mounted on the frame 110, the screen assembly 121 and the driver IC in the display assembly 120 are less prone to breakage, ensuring the reliability of the display assembly 120.
[0031] In one possible application, the display assembly 120 includes a screen assembly 121 and a driver IC (Integrated Circuit) 122, which is mounted on the inner side of the screen assembly 121.
[0032] For example, the waterproof and breathable component 140 is a waterproof and breathable membrane.
[0033] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the edges of the waterproof and breathable element 140 and the pressure relief mesh 150 are sealed to the frame 110.
[0034] The edge of the pressure relief net 150 is sealed to the frame 110. When water from outside the electronic device 100 enters the sound guide channel 111, the water cannot pass through the space between the pressure relief net 150 and the frame 110. Instead, the water can only pass through the pressure relief net 150 to enter the space between the pressure relief net 150 and the waterproof and breathable component 140, ensuring that the pressure relief net 150 can stably relieve the pressure of the water.
[0035] The edge of the waterproof and breathable component 140 is sealed to the frame 110, preventing external water from passing through the waterproof and breathable component 140 between the waterproof and breathable component 140 and the frame 110, thus ensuring that the waterproof and breathable component 140 can effectively block external water and improve the waterproof effect inside the electronic device 100.
[0036] For example, a first seal 161 is provided between the edge of the waterproof and breathable component 140 and the frame 110. The first seal 161 can be a sealant, sealing foam, or sealing silicone gasket, etc. A second seal 162 is provided between the pressure relief mesh 150 and the frame 110. The second seal 162 can be a sealant, sealing foam, or sealing silicone gasket, etc.
[0037] In some embodiments, optionally, the frame 110 is provided with a groove 112, one end of the second channel 114 away from the first channel 113 is disposed at the bottom of the groove 112, and the waterproof and breathable component 140 and the pressure relief net 150 are stacked on the bottom of the groove 112, and the projected area of the waterproof and breathable component 140 and the pressure relief net 150 on the plane where the bottom of the groove 112 is located is greater than or equal to the projected area of the end of the second channel 114 away from the first channel on the plane where the bottom of the groove 112 is located.
[0038] The bottom of the groove 112 is connected to the second channel 114. The waterproof and breathable component 140 and the pressure relief net 150 are installed at the bottom of the groove 112, thus covering the end of the second channel 114. Because the pressure relief net 150 is in close contact with the bottom of the groove 112, there is a large contact area between the pressure relief net 150 and the frame 110, ensuring the stability of the connection of the pressure relief net 150 to the frame 110. When high-pressure water impacts the pressure relief net 150, the pressure relief net 150 is less likely to detach from the frame 110, and the pressure relief net 150 can stably relieve the pressure of the high-pressure water flow.
[0039] like Figure 2 As shown, in some embodiments, the electronic device 100 may optionally include a circuit board 133, which is disposed in the slot of the groove 112, and a microphone 131 is disposed on the side of the circuit board 133 away from the sound guiding channel 111. The circuit board 133 is provided with a through hole 134, and the microphone 131 is connected to the second channel 114 through the through hole 134.
[0040] The circuit board 133 is positioned at the opening of the groove 112, keeping it away from the bottom of the groove 112. Even if water seeps into the groove 112, it is unlikely to come into contact with the circuit board 133. A through hole 134 is machined into the circuit board 133, which avoids obstructing the microphone's sound pickup path.
[0041] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, optionally, along the extending direction of the second channel 114 ( Figure 1 and Figure 3 (The arrow at A1 points to) the second channel 114 and the through hole 134 are misaligned.
[0042] The second channel 114 and the through hole 134 are misaligned. That is, the through hole 134 is not provided in the extension direction of the second channel 114. When the water flows out of the second channel 114 along the extension direction of the second channel 114, the return flow will not flow directly to the through hole 134. Instead, the water needs to turn again and flow to the through hole 134. This method can further depressurize the water flow and further reduce the damage rate of the waterproof and breathable component 140.
[0043] like Figure 2 As shown, the second channel 114 faces the position on the circuit board 133 where there is no through hole 134; the water flow needs to change direction to reach the through hole 134. Figure 3 As shown, a channel is also provided between the second channel 114 and the through hole 134.
[0044] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the pressure relief mesh 150 is attached to the bottom of the groove 112, and the pressure relief mesh 150 covers the end of the second channel 114, with the waterproof and breathable component 140 spaced apart from the pressure relief mesh 150.
[0045] A portion of the waterproof and breathable component 140 is located within the groove 112, and the waterproof and breathable component 140 is spaced apart from the pressure relief net 150, thereby forming a gap 180 between the waterproof and breathable component 140 and the pressure relief net 150. Even if the water flowing through the pressure relief net 150 still carries a certain water pressure, the space between the waterproof and breathable component 140 and the pressure relief net 150 can further relieve the pressure of the water flow. The water pressure when the water flow reaches the waterproof and breathable component 140 is relatively small, further reducing the damage rate of the waterproof and breathable component 140.
[0046] Combination Figure 3 and Figure 4 As shown, the pressure relief net 150 includes a first part 151 and a second part 152 connected to each other. The first part 151 is located on the outer periphery of the second part 152 and is sealed to the waterproof and breathable component 140. The second part 152 is located in the second channel 114. The distance between the second part 152 and the waterproof and breathable component 140 is greater than the distance between the first part 151 and the waterproof and breathable component 140. The second part 152 is provided with a mesh 155 so that the sound outlet 135 of the microphone 131 is connected to the second channel 114 through the mesh 155.
[0047] The pressure relief net 150 includes a first part 151 and a second part 152, with the second part 152 connected to the first part 151. The first part 151 is sealed to the waterproof and breathable component 140, and the second part 152 is spaced apart from the waterproof and breathable component 140, thus forming a gap 180 between the second part 152 and the waterproof and breathable component 140. Even if the water flowing through the pressure relief net 150 still carries a certain water pressure, the space between the waterproof and breathable component 140 and the second part 152 can further relieve the pressure on the water flow, resulting in lower water pressure when the water reaches the waterproof and breathable component 140, further reducing the damage rate of the waterproof and breathable component 140.
[0048] For example, a third seal 163 is provided between the waterproof and breathable component 140 and the pressure relief mesh 150. The third seal 163 can be a sealant, sealing foam, or sealing silicone gasket, etc.
[0049] The second part 152 has mesh openings 155, allowing external sound and water flow to pass through the pressure relief net 150 only through the mesh openings 155. In this embodiment, no mesh openings 155 are provided on the first part 151, preventing water flow from passing through it and avoiding impact on the position of the waterproof and breathable component 140 directly opposite the first part 151, thus reducing the damage rate of the waterproof and breathable component 140. Moreover, the mesh openings 155 are only provided in certain positions on the pressure relief net 150, avoiding excessive mesh openings 155 from affecting the structural strength of the pressure relief net 150, ensuring that the pressure relief net 150 has strong structural strength, and preventing deformation of the pressure relief net 150 under the impact of water flow.
[0050] In one possible application, the first part 151 and the second part 152 are an integral structure.
[0051] Combination Figure 3 and Figure 4 As shown, in some embodiments, optionally, the second part 152 includes a connecting part 153 and a pressure relief part 154. One side of the connecting part 153 is connected to the first part 151, and the other side of the connecting part 153 is connected to the pressure relief part 154. The pressure relief part 154 is provided with a mesh 155.
[0052] The connecting part 153 is connected to the first part 151, and the connecting part 153 is bent away from the microphone 131 relative to the first part 151. The pressure relief part 154 is connected to the side of the connecting part 153 away from the first part 151, thereby spacing the pressure relief part 154 from the waterproof and breathable part 140.
[0053] In this embodiment, only the pressure relief part 154 has a mesh 155, while the connecting part 153 does not have a mesh 155. The water flow can only pass through the pressure relief part 154 and not through the connecting part 153. This is equivalent to not having a mesh 155 on the side of the second part 152. When a part of the water flow impacts the side of the second part 152, the side of the second part 152 can relieve the pressure of the water flow, which can reduce the impact of the water flow on the structure near the mesh 155 and reduce the damage rate of the structure near the mesh 155.
[0054] In one possible application, the connecting part 153 and the pressure relief part 154 are an integral structure.
[0055] Combination Figure 2 and Figure 3 As shown, in some embodiments, optionally, a protrusion 170 is provided on the frame 110. The protrusion 170 is located at the connection between the first channel 113 and the second channel 114, and the protrusion 170 is provided on the channel wall on the side of the first channel 113 and / or the second channel 114 away from the sound guide hole 116.
[0056] A protrusion 170 is provided inside the frame 110. The protrusion 170 is located on the channel wall of the first channel 113 and / or the second channel 114 on the side away from the sound guide hole 116. When water flows to the end of the first channel 113 away from the sound guide hole 116, the water will flow in the opposite direction within the first channel 113 due to the obstruction of the protrusion 170. During the water flow reversal, the water pressure will decrease, thereby relieving the pressure of the water flow and reducing the probability of water flow damaging the waterproof and breathable component 140.
[0057] like Figure 1 As shown, in some embodiments, the electronic device 100 may optionally include a shield 190, which is disposed outside the microphone 131 and is fixedly connected to the circuit board 133.
[0058] The microphone 131 is located in the space between the shielding cover 190 and the circuit board 133. The shielding cover 190 protects the microphone 131 and prevents other components from contacting the microphone 131, which helps to reduce the damage rate of the microphone 131.
[0059] like Figure 1 As shown, in some embodiments, optionally, the through direction of the first channel 113 is parallel to the extension direction of the circuit board 133.
[0060] The circuit board 133 typically extends along the length and width of the frame 110. The through direction of the first channel 113 is parallel to the extension direction of the circuit board 133. Therefore, the first channel 113 does not occupy the space of the frame in the thickness direction, thereby leaving installation space for other components at the bottom of the body and reducing the layout pressure inside the electronic device 100.
[0061] In one possible application, the first channel 113 extends along the length of the frame 110, thereby reducing the space occupied by the first channel 113 in the width direction of the frame 110.
[0062] like Figure 3 As shown, in some embodiments, optionally, the first channel 113 includes a first flow channel section 1131 and a second flow channel section 1132 that are interconnected, the first flow channel section 1131 is adjacent to the sound guide hole 116, and the aperture of the first flow channel section 1131 is larger than the aperture of the second flow channel section 1132.
[0063] The aperture of the first flow channel section 1131 is larger than that of the second flow channel section 1132. When the water flows through the connection between the first flow channel section 1131 and the second flow channel section 1132, the second flow channel section 1132 will reduce the flow velocity of the water, so that the water flowing towards the pressure relief net 150 has been decelerated.
[0064] Combination Figure 2 and Figure 3 As shown, in some embodiments, the electronic device 100 may optionally include a display assembly 120 mounted on a housing 110, and a circuit board 133 mounted on a side of the housing 110 opposite to the display assembly 120. A second channel 114 extends in a direction opposite to the display assembly 120, and the second channel 114 is located between the two ends of the first channel 113.
[0065] The second channel 114 is located between the two ends of the first channel 113. When the water flows from the first end of the first channel 113 to the second end of the first channel 113, the second end of the first channel 113 serves as a pressure relief point in the sound guide channel 111. When the water flows to the second end of the first channel 113, the water will flow in the opposite direction and then flow to the second channel 114. During the process of the water flow turning, the water pressure will decrease, thus achieving pressure relief of the water flow.
[0066] like Figure 3 As shown, in some embodiments, the second channel 114 may optionally have a bent section.
[0067] A section of the second channel 114 is bent, and the bend in the second channel 114 serves as a pressure relief point. The water flow changes direction within the second channel 114, and the water pressure decreases during the change of direction, thus further relieving the pressure on the water flow.
[0068] Combination Figure 3 and Figure 5 As shown, in some embodiments, optionally, the display assembly 120 is along a first direction ( Figure 3 and Figure 5 The dimension (indicated by the arrow at point A2) is greater than that along the second direction ( Figure 5 The dimension (pointed to by the arrow at A4) is such that the first direction is perpendicular to the second direction, and both the first and second directions are perpendicular to the thickness direction of the display assembly 120. Figure 2 (The arrow at A3 points to) the first channel 113 extends along the first direction.
[0069] Both the first direction and the second direction are perpendicular to the thickness direction of the display assembly 120, and the dimension of the display assembly 120 along the first direction is greater than the dimension along the second direction. For example, the first direction can be the length direction of the display assembly 120, and the second direction can be the width direction of the display assembly 120.
[0070] The first channel 113 extends along the first direction, that is, the first channel 113 extends along the length direction of the display assembly 120. The first channel 113 will not occupy too much space in the width direction of the electronic device 100, thereby leaving installation space for other components at the bottom of the device and reducing the layout pressure inside the electronic device 100.
[0071] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the pressure relief net 150 may optionally include a dustproof mesh 156 or a metal mesh 157. Exemplarily, the metal mesh 157 is a steel mesh.
[0072] Mobile phones are increasingly emphasizing reliability design, and waterproofing is a major direction for improving reliability. While pursuing the ultimate stacking utilization, the goal is to leverage minimal space to enhance overall waterproofing. IPX9 (an internationally recognized testing standard for evaluating the waterproof performance of electronic devices under high-pressure water jet conditions. This standard requires devices to withstand high-pressure water jets at specific pressures and distances, ensuring normal operation in humid environments) waterproofing designs often encounter many stacking bottlenecks and design limitations when waterproofing the microphone channel.
[0073] The purpose of this embodiment is to provide a design that can both accommodate limited horizontal layout space and avoid slotting in the middle frame below the driver IC, ensuring the reliability and flatness of the middle frame below the driver IC, while also meeting the overall IPX9 waterproof reliability requirement.
[0074] Improvements in this embodiment:
[0075] First, the sound guide channel 111 is designed by utilizing the longitudinal and thickness directions to improve space utilization.
[0076] Second, ensure the reliability of the driver IC and reduce the failure rate of the display component 120.
[0077] The technical solution of this embodiment is to design a tortuous sound-conducting channel 111 in the longitudinal and thickness directions, and to design an additional layer of pressure relief protection below the waterproof and breathable membrane.
[0078] In the first implementation, the sound guiding channel 111 has multiple pressure relief points designed in the longitudinal and thickness directions. The steel mesh is fixed and sealed to the frame 110 by adhesive dots or backing adhesive. The outer dimensions of the steel mesh are the same as the dimensions of the waterproof and breathable membrane. The waterproof and breathable membrane is sealed to the steel mesh by backing adhesive, occupying little of the overall lateral space of the machine. After the water pressure enters the channel at the moment of impact, it decreases after passing through multiple pressure relief points (in conjunction with...). Figure 2 and Figure 3 As shown, the first pressure relief point a changes the direction of water pressure, making the water flow direction opposite to the original direction, and the second pressure relief point b changes the direction of water flow to be perpendicular to the original direction. After passing through the steel mesh with the same length and width as the waterproof and breathable membrane, the water pressure becomes smaller. After the water pressure reaches the waterproof and breathable membrane, it reduces the destructive force on the waterproof and breathable membrane, thereby protecting the waterproof and breathable membrane and the microphone 131.
[0079] In the second implementation method, similar to the first implementation method, a tortuous channel is designed in the longitudinal and thickness directions of the whole machine. The difference is that the steel mesh is replaced with a dustproof mesh 156.
