Description

Technical Field

[0001] This application belongs to the field of waterproof technology, specifically relating to an electronic device. Background Technology

[0002] Electronic devices typically have an internal acoustic module. To ensure that sound waves in the environment of the electronic device can be smoothly transmitted to or from the acoustic module for sound acquisition and playback, the casing of the electronic device often has a sound guiding channel to ensure that sound waves can pass through without obstruction.

[0003] In related technologies, a waterproof and breathable membrane is typically placed between the sound guide channel and the acoustic module to prevent liquids from entering the electronic device through the sound guide channel. However, when the electronic device is impacted by liquid, the liquid can easily enter the device through the sound guide channel and impact the waterproof and breathable membrane, causing wrinkles or even damage. This leads to the failure of the waterproof function of the membrane, allowing external liquid to enter the electronic device through the damaged areas. This can cause short circuits or malfunctions in components such as the acoustic module or circuit board, rendering the electronic device unusable. Summary of the Invention

[0004] The purpose of this application is to provide an electronic device that can solve the problem in the related art that the waterproof and breathable membrane is easily damaged by liquid, causing liquid to enter the electronic device and damage the device.

[0005] This application provides an electronic device, which includes: Acoustic module; The housing has a through hole and a sound guiding channel communicating with the through hole. The through hole is connected to the external environment, and the sound guiding channel is disposed opposite to the acoustic module. A sealing baffle is rotatably disposed within the sound guiding channel. When the sealing baffle is subjected to liquid impact, it can rotate from a first position to a second position. When the sealing baffle is in the first position, a gap is left between the sealing baffle and at least a portion of the sidewall of the sound guiding channel. When the sealing baffle is in the second position, the sealing baffle seals the sound guiding channel. A reset member is connected to the sealing stop member, and the reset member is used to drive the sealing stop member to rotate from the second position to the first position.

[0006] In this embodiment, the sealing baffle is rotatably disposed within the sound guiding channel. When liquid impacts the sealing baffle, the impact force of the liquid drives the sealing baffle to rotate from the first position to the second position, thereby sealing the sound guiding channel to block the liquid from impacting the waterproof and breathable membrane. This prevents the waterproof and breathable membrane from wrinkling or even breaking, thereby improving the waterproof effect of the electronic device, preventing liquid from entering the electronic device, which is beneficial to ensuring the performance of acoustic modules or circuit boards and other devices, and also beneficial to extending the service life of acoustic modules or circuit boards and other devices.

[0007] When there is no liquid impact, the reset member can drive the sealing stop to rotate from the second position to the first position, so that a gap is left between the sealing stop and at least part of the side wall of the sound guide channel, so that the sound wave can be transmitted to the acoustic module through the gap or the sound emitted by the acoustic module can be transmitted out through the gap, so as to avoid the sealing stop affecting the transmission of the sound wave.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0012] The electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0013] refer to Figures 1-7 An electronic device provided in this application embodiment may include an acoustic module 300, a housing 100, a sealing baffle 500, and a reset component 600.

[0014] Among them, such as Figure 1 As shown, the housing 100 may be provided with a through hole 101 and a sound guiding channel 111 communicating with the through hole 101. The through hole 101 may be connected to the external environment, and the sound guiding channel 111 may be arranged opposite to the acoustic module 300 to ensure that sound waves can pass through without obstruction and be collected by the acoustic module 300, or to transmit the sound emitted by the acoustic module 300.

[0015] In some embodiments, the electronic device may further include a waterproof and breathable membrane 400, which may be disposed between the acoustic module 300 and the sound guiding channel 111, and the waterproof and breathable membrane 400 may seal the sound guiding channel 111 to prevent liquids or the like from entering the interior of the electronic device through the sound guiding channel 111. Of course, the electronic device may also not include the waterproof and breathable membrane 400.

[0016] like Figure 1As shown, the sealing baffle 500 is rotatably disposed within the sound guiding channel 111. When subjected to liquid impact, the sealing baffle 500 can rotate from a first position to a second position. When the sealing baffle 500 is in the first position, a gap is left between the sealing baffle 500 and at least a portion of the sidewall of the sound guiding channel 111 to ensure that sound waves can pass through. When the sealing baffle 500 is in the second position, the sealing baffle 500 seals the sound guiding channel 111 to prevent liquid from entering the electronic device through the sound guiding channel 111 and to prevent liquid from impacting the waterproof and breathable membrane 400 and causing damage to the waterproof and breathable membrane 400. In this embodiment, the sealing baffle 500 can be a plate-like structure.

[0017] The reset member 600 can be connected to the sealing stop 500. The reset member 600 can be used to drive the sealing stop 500 to rotate from the second position to the first position so that the sealing stop 500 can automatically return to the first position.

[0018] In this embodiment, the sealing baffle 500 is rotatably disposed within the sound guiding channel 111. When liquid impacts the sealing baffle 500, the impact force of the liquid drives the sealing baffle 500 to rotate from the first position to the second position, thereby sealing the sound guiding channel 111 and preventing liquid from impacting the waterproof and breathable membrane 400. This prevents the waterproof and breathable membrane 400 from wrinkling or even breaking, thereby improving the waterproof effect of the electronic device and enabling it to meet the IPX9 waterproof rating. This prevents liquid from entering the interior of the electronic device, which is beneficial for ensuring the performance of devices such as the acoustic module 300 or circuit board 200, and for extending the service life of devices such as the acoustic module 300 or circuit board 200.

[0019] When there is no liquid impact, the reset member 600 can drive the sealing stop 500 to rotate from the second position to the first position, so that a gap is left between the sealing stop 500 and at least part of the side wall of the sound guide channel 111, so that the sound wave can be transmitted to the acoustic module 300 through the gap or the sound emitted by the acoustic module 300 can be transmitted out through the gap, so as to avoid the sealing stop 500 affecting the transmission of the sound wave.

[0020] In this embodiment, as Figure 1 As shown, the housing 100 may include a middle frame 110 and a battery cover 120 covering the middle frame 110. A sound guide channel 111 and a through hole 101 may be disposed on the middle frame 110. A mounting space 130 is formed between the battery cover 120 and the middle frame 110. The circuit board 200 and the acoustic module 300 may be disposed within the mounting space 130. Figure 7 As shown, a mounting groove 113 can also be provided on the middle frame 110. The mounting groove 113 is positioned opposite to the acoustic module 300. The sound guiding channel 111 is connected to the mounting groove 113. The waterproof and breathable membrane 400 is disposed in the mounting groove 113.

[0021] In an optional embodiment, the reset member 600 may include a counterweight block, which may be connected to the sealing stop member 500. The center of gravity of the counterweight block may be offset from the rotation axis of the sealing stop member 500, and the counterweight block may be used to drive the sealing stop member 500 back to the first position.

[0022] Because the center of gravity of the counterweight is offset from the rotation axis of the sealing baffle 500, the counterweight can be formed as a driving structure. When there is no water flow impact, the counterweight will drive the sealing baffle 500 to remain stably in the first position, so that a gap is formed between the sealing baffle 500 and the side wall of the sound guide channel 111 to ensure the passage of sound. When there is water flow impact, the water flow impact force is greater than the weight of the counterweight, and the sealing baffle 500 can overcome the weight of the counterweight and rotate from the first position to the second position, sealing the sound guide channel 111. When the water flow disappears, without additional power or magnetic adsorption, the sealing baffle 500 can automatically return to the first position under the action of the weight of the counterweight.

[0023] In this embodiment, compared to driving the sealing stop 500 to reset through structures such as elastic or magnetic components, using the gravity of the counterweight as the driving force source is less affected by external factors such as temperature, humidity, and electromagnetic environment. Furthermore, the structure is simple, easy to set up, and can reduce assembly and production costs.

[0024] In this embodiment, the sealing baffle 500 can be made of non-metallic materials such as plastic. This reduces manufacturing costs and makes it less prone to corrosion from contact with liquids, thus extending its service life. The counterweight and sealing baffle 500 can be an integral structure or separate structures. The counterweight can be fixed to the sealing baffle 500 with screws or adhesive.

[0025] In another optional embodiment, the reset member 600 may include an elastic member, one end of which may be connected to the sealing stop 500, and the other end of which may be connected to the side wall of the sound guiding channel 111. The elastic member can be used to drive the sealing stop 500 back to the first position. In this embodiment, compared to driving the sealing stop 500 to reset through the gravity of the counterweight or a magnetic adsorption structure, the elastic member can quickly release elastic potential energy the instant the liquid impact force disappears, driving the sealing stop 500 to quickly reset to the first position, thus avoiding problems such as jamming or delay during the reset process.

[0026] Here, the sealing baffle 500 can be made of non-metallic materials such as plastic. This can reduce manufacturing costs and prevent corrosion from contact with liquids, thus extending the service life of the sealing baffle 500.

[0027] In this embodiment, the sealing stop 500 can be rotatably disposed in the sound guide channel 111 via the fixed shaft 700.

[0028] In some embodiments, the elastic element can be a torsion spring, which can be sleeved outside the fixed shaft 700. The first torsion arm of the torsion spring can be connected to the sealing stop 500, and the second torsion arm of the torsion spring can be directly connected to the side wall of the sound guide channel 111, or the second torsion arm of the torsion spring can be connected to the fixed shaft 700. Here, compared to using a compression spring as the elastic element, setting the elastic element as a torsion spring occupies less space and can directly apply a rotational force to the sealing stop 500, making it easier for the sealing stop 500 to rotate to the first position.

[0029] In other embodiments, the elastic element may also be a compression spring, with one end of the compression spring connected to the sealing stop 500 and the other end of the compression spring connected to the side wall of the sound guide channel 111.

[0030] In yet another alternative embodiment, such as Figure 1 As shown, the reset member 600 may include a first magnetic member 610, which can be magnetically attracted to the sealing stop 500 to drive the sealing stop 500 back to the first position. In this embodiment, the first magnetic member 610 drives the sealing stop 500 to reset by magnetic attraction. Compared with the method of driving the sealing stop 500 to reset by elastic members or counterweights, there is no need for connection between the first magnetic member 610 and the sealing stop 500, which facilitates assembly.

[0031] In an optional embodiment, the sealing stop 500 may include a first portion 510 and a second portion 520 connected to the first portion 510, wherein the first portion 510 and the second portion 520 may be located on opposite sides of the rotation axis of the sealing stop 500.

[0032] The first part 510 may be equipped with a second magnetic component or may be made of a ferromagnetic material, and may be magnetically attracted to the first magnetic component 610. It should be noted that ferromagnetic materials include iron, cobalt, nickel and their alloys or iron oxides, etc.

[0033] Compared to a sealing baffle 500 that has a second magnetic element or is made entirely of ferromagnetic material, this configuration allows the force exerted by the first magnetic element 610 on the sealing baffle 500 to be more concentrated, making it easier to drive the sealing baffle 500 to rotate to the first position. Furthermore, by setting the second magnetic element only in the first part 510 or by making only the first part 510 of ferromagnetic material, processing costs can be reduced.

[0034] In other embodiments, the sealing baffle 500 may be provided with a second magnetic element or may be made entirely of a ferromagnetic material.

[0035] In optional embodiments, such as Figure 3 and Figure 4 As shown, the thickness of the first part 510 is greater than the thickness of the second part 520. This arrangement makes the gravity of the first part 510 greater than the gravity of the second part 520, so that the first part 510 tends to rotate toward the first magnetic element 610, thereby facilitating the magnetic attraction between the first part 510 and the first magnetic element 610.

[0036] It should be noted that the thickness of the first part 510 is greater than the thickness of the second part 520, which allows the center of gravity of the first part 510 to be closer to the first magnetic element 610 than that of the second part 520, making it easier for the first part 510 to rotate toward the first magnetic element 610. Here, the thickness direction of the first part 510 and the second part 520 is perpendicular to the rotation axis of the sealing stop 500 and also perpendicular to the arrangement direction of the first part 510 and the second part 520.

[0037] Furthermore, in this embodiment, the gravity of the first part 510 and the magnetic attraction force of the first magnetic element 610 can form a dual reset driving force, making it easier for the sealing stop 500 to return to the first position. Moreover, even when the magnetic attraction force is weakened due to environmental factors or when the sealing stop 500 is affected by external magnetic fields, the sealing stop 500 can still rotate to the first position by relying on the gravity of the first part 510, thereby effectively avoiding the situation where the sealing stop 500 cannot be reset and thus affects the acoustic performance.

[0038] In other embodiments, the thickness of the first portion 510 may also be less than or equal to the thickness of the second portion 520.

[0039] In this embodiment, when the sealing baffle 500 is in the second position, the first part 510 is located above the second part 520. With this arrangement, when the water flow disappears, that is, when the sealing baffle 500 is no longer impacted by the liquid, the first part 510 is more likely to rotate toward the first magnetic element 610 under its own gravity.

[0040] In some embodiments, the thickness of the second portion 520 is greater than the thickness of the first portion 510, meaning the second portion 520 is heavier than the first portion 510. When the sealing stop 500 is in the second position, the second portion 520 is located above the first portion 510. When the water flow disappears, the second portion 520 rotates away from the first magnetic member 610 under its own weight. Driven by the second portion 520, the first portion 510 rotates towards the first magnetic member 610, making it easier for the first portion 510 to be attracted by the first magnetic member 610.

[0041] In optional embodiments, such as Figure 4As shown, the first magnetic component 610 may be provided with a first inclined surface 611, and the sealing baffle 500 may be provided with a second inclined surface 511. When the sealing baffle 500 is in the first position, the sealing baffle 500 is supported on the first inclined surface 611 by the second inclined surface 511. In this embodiment, the first inclined surface 611 and the second inclined surface 511 are in contact, which can restrict the sealing baffle 500 to the first position and ensure that the sealing baffle 500 can be inclined. In this way, on the one hand, a gap can be formed between the sealing baffle 500 and at least part of the sidewall of the sound guiding channel 111, and on the other hand, it is convenient for the sealing baffle 500 to rotate under the impact of liquid. Furthermore, through the contact of the first inclined surface 611 and the second inclined surface 511, compared with the point contact or line contact between the sealing baffle 500 and the first magnetic component 610, the contact area between the first magnetic component 610 and the sealing baffle 500 is larger and the stress distribution is more uniform. This can effectively reduce the wear of the sealing baffle 500 during the reset process. In addition, the first magnetic component 610 can play a limiting role while playing a magnetic attraction role, so there is no need to set an additional limiting structure to limit the sealing baffle 500.

[0042] Here, when the sealing baffle 500 is in the first position, the angle between the sealing baffle 500 and the axis of the second channel 1112 described below can be 30° to 60°. Of course, the angle between the sealing baffle 500 and the axis of the second channel 1112 can also be greater than or equal to 0° and less than 30°. In this embodiment, when the sealing baffle 500 is in the first position, the angle between the sealing baffle 500 and the axis of the second channel 1112 can be 30°. When the sealing baffle 500 is impacted by liquid, it can rotate 60°, at which point the sealing baffle 500 is perpendicular to the axis of the second channel 1112, thus sealing the sound guide channel 111.

[0043] In other embodiments, the first inclined surface 611 may not be provided on the first magnetic element 610, and the second inclined surface 511 may not be provided on the sealing stop 500. For example, when the sealing stop 500 is in the first position, the sealing stop 500 is parallel to the axis of the second channel 1112 described below, that is, the angle between the sealing stop 500 and the axis of the second channel 1112 is 0°. When the sealing stop 500 is in the second position, the angle between the sealing stop 500 and the axis of the second channel 1112 is 90°.

[0044] In an optional embodiment, the electronic device may further include a fixed axis 700, such as Figure 7As shown, the fixed shaft 700 can be disposed within the housing 100, and at least a portion of the fixed shaft 700 can be located within the sound guide channel 111. The sealing stop 500 is rotatably disposed on the fixed shaft 700, and the reset member 600 is disposed on the fixed shaft 700. In this embodiment, compared to disposing the reset member 600 on the side wall of the sound guide channel 111, disposing the reset member 600 on the fixed shaft 700 eliminates the need to create a slot or hole for mounting the reset member 600 on the side wall of the sound guide channel 111. When installing the sealing stop 500 and the reset member 600, the sealing stop 500 and the reset member 600 can be first installed onto the fixed shaft 700, and then the fixed shaft 700, the sealing stop 500, and the reset member 600 can be assembled into the sound guide channel 111, facilitating assembly.

[0045] In other embodiments, the reset member 600 may be disposed on the side wall of the sound guide channel 111.

[0046] Optionally, the reset component 600 is detachably mounted on the fixed shaft 700, which facilitates the assembly and disassembly of the reset component 600.

[0047] For example, such as Figure 4 and Figure 6 As shown, a fixing groove 710 can be provided on the fixed shaft 700, and a portion of the reset member 600 can be embedded in the fixing groove 710 to achieve a detachable connection between the reset member 600 and the fixed shaft 700. Here, the reset member 600 can be a first magnetic member 610. Figure 6 As shown, the sealing stop 500 may be provided with a connecting hole 501, and the fixed shaft 700 passes through the connecting hole 501 to realize the rotational connection between the sealing stop 500 and the connecting hole 501.

[0048] Optionally, such as Figure 7 As shown, the housing 100 can also be provided with two connecting grooves 112. The two connecting grooves 112 can be located on opposite sides of the sound guide channel 111 and can both communicate with the sound guide channel 111. The two ends of the fixed shaft 700 can extend into the two connecting grooves 112 respectively and can be connected to the groove walls of the two connecting grooves 112 respectively, so as to realize the connection between the fixed shaft 700 and the housing 100. Compared with the method of bonding or abutting the two ends of the fixed shaft 700 to the side walls of the sound guide channel 111 respectively, this configuration can effectively improve the connection strength and stability between the fixed shaft 700 and the housing 100, and facilitate the assembly of the fixed shaft 700.

[0049] Of course, the connecting groove 112 may not be provided on the housing 100, and the two ends of the fixed shaft 700 may be bonded or abutted to the side wall of the sound guide channel 111 respectively.

[0050] like Figure 7As shown, in order to improve the stability of the fixed shaft 700 assembly and prevent the fixed shaft 700 from loosening, both ends of the fixed shaft 700 can be connected to the groove walls of the two connecting grooves 112 by fixing adhesive 800.

[0051] In optional embodiments, such as Figures 1-3 As shown, the sound guiding channel 111 may include a first channel 1111 and a second channel 1112 communicating with the first channel 1111. The first channel 1111 may communicate with the through hole 101, and the end of the second channel 1112 away from the first channel 1111 may be disposed opposite to the acoustic module 300. Here, the axial direction of the first channel 1111 intersects the axial direction of the second channel 1112. In this embodiment, the connection between the first channel 1111 and the second channel 1112 can form a bent channel. When liquid enters the first channel 1111 from the through hole 101, the flow direction changes due to the bend of the channel, which greatly weakens the inertial impact force of the liquid, thereby reducing the impact force of the liquid on the waterproof and breathable membrane 400.

[0052] Optionally, the sealing baffle 500 is rotatably disposed within the second channel 1112. With this arrangement, the sealing baffle 500 is subjected to less impact force from the liquid, and is less likely to fail to seal the second channel 1112 due to excessive rotation angle caused by excessive impact force.

[0053] Of course, the sealing baffle 500 can also be rotatably installed in the first channel 1111.

[0054] This embodiment of the application can protect the waterproof and breathable membrane 400 from failure due to impact from high-speed water flow, thereby solving the problem that the waterproof solution of the acoustic module 300 in the related technology cannot meet the IPX9 level waterproof requirements, which leads to the inability of the whole machine to be used in scenarios such as rain, continuous impact from water guns, and water splashing festivals, thus helping to achieve the best protection performance of the whole machine.

[0055] Alternatively, the electronic device can be a mobile phone, tablet computer, wearable device, or other electronic product.

[0056] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
