Description

Technical Field

[0001] This disclosure relates to the field of electronic products, and more particularly to an electronic device. Background Technology

[0002] With the rapid development of technology, people have increasingly higher requirements for electronic products, with product quality being a key concern. To prevent pressure imbalances that could cause rattling noises when pressing buttons, a small hole is typically made in the frame, connecting to the inside of the frame. A waterproof and breathable membrane then connects to the frame, achieving both waterproofing and dustproofing while maintaining pressure balance. However, creating a small hole in the frame increases manufacturing costs and design complexity, and currently, most electronic products on the market only meet IP68 (dust and water resistance) standards. However, the diversification of user needs has spurred the development of higher waterproofing requirements. For example, swimming in water depths exceeding 1.5 meters, rafting in summer, or encountering rainy weather may require higher levels of waterproofing and dustproofing. Utility Model Content

[0025] The technical solutions in the embodiments (or "implementations") of this disclosure will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0026] If this disclosure uses terms relating to directional indications or positional relationships (e.g., up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, terms such as "first" and "second" in this disclosure are used only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0027] like Figures 1 to 3 As shown, the electronic device disclosed herein includes a mid-frame 1, a waterproof and breathable membrane 2, a sound transmission seam 3, a panel assembly 4, an air duct 5, a pressing component 6, and a circuit board (not shown). The mid-frame 1 includes a frame 11 and a support plate 12, the support plate 12 being fixed within the frame 11. The support plate 12 can be used to support the panel assembly 4, the pressing component 6, and the circuit board.

[0028] The support plate 12 is provided with an air hole 121 and a pressing cavity 122. Along the thickness direction of the middle frame 1, the air hole 121 penetrates the support plate 12 and communicates with the pressing cavity 122. The pressing cavity 122 is located on the side of the support plate 12 away from the panel assembly 4. Specifically, the pressing cavity 122 is recessed from one side of the support plate 12 toward the panel assembly 4.

[0029] A waterproof and breathable membrane 2 is attached to the support plate 12 and covers the vent 121. This allows the membrane to isolate liquids while allowing gas to enter the electronic device when external gases or liquids enter. The sound transmission seam 3 connects to the outside of the electronic device, and the vent 121 communicates with the sound transmission seam 3. This arrangement eliminates the need for small holes in the frame 11 while maintaining air pressure balance inside and outside the frame 1, improving the waterproof and dustproof performance of the electronic device, simplifying its design, and reducing manufacturing and design costs.

[0030] The waterproof and breathable membrane 2 is attached to the side of the support plate 12 away from the panel assembly 4. Specifically, the waterproof and breathable membrane 2 is located inside the pressing cavity 122.

[0031] In some embodiments, the sound transmission slit 3 includes a sound outlet gap for the earpiece, a sound outlet gap for the speaker, or a sound pickup gap for the microphone. The sound transmission slit 3 is located between the outer edge of the panel assembly 4 and the inner side of the frame 11. Admittedly, the sound transmission slit 3 may also be located on the frame 11.

[0032] Furthermore, when the sound transmission slit 3 serves as the earpiece sound outlet gap, it is located between the outer edge of the panel assembly 4 and the inner side of the frame 11. When the sound transmission slit 3 serves as the speaker sound outlet gap or the microphone sound pickup gap, it can also be located on the frame 11. By utilizing the inherent design gaps of the electronic device, the vent 121 is connected to this gap, avoiding the need to create small holes on the frame 11, simplifying the design of the electronic device, and reducing manufacturing and design costs.

[0033] Admittedly, without affecting the function of the electronic device, the vent 121 can also connect with other gaps in the electronic device, thereby avoiding the need for additional openings on the electronic device, reducing the manufacturing cost of the electronic device, and improving the aesthetics of the electronic device.

[0034] Further integration Figure 4 and Figure 5 As shown, in some embodiments, the panel assembly 4 is located within the frame 11 and on one side of the support plate 12. The panel assembly 4 is spaced apart from the waterproof and breathable membrane 2. The panel assembly 4 includes a top side edge 41 and a sound groove 42 recessed from the top side edge 41. The top side edge 41 contacts the inner side of the frame 11, and the sound groove 42 forms a sound transmission seam 3 with the frame 11.

[0035] The air duct 5 is located between the carrier plate 12 and the panel assembly 4, and connects the sound transmission seam 3 and the air hole 121. When external gas and liquid enter the electronic device, they first enter through the sound transmission seam 3 and flow along the thickness direction of the middle frame 1, down the inner side of the frame 11 to the upper side of the carrier plate 12. Subsequently, the external gas and liquid enter the air duct 5 and flow into the air hole 121. At this time, the gas passes through the waterproof and breathable membrane 2 to enter the other side of the carrier plate 12 to achieve air pressure balance inside and outside the middle frame 1, while the liquid is isolated by the waterproof and breathable membrane 2 to prevent it from entering the other side of the carrier plate 12 and damaging the circuit board, thereby achieving the waterproof and dustproof function of the electronic device.

[0036] In some embodiments, both the waterproof and breathable membrane 2 and the pressing member 6 are located on the side of the support plate 12 opposite to the panel assembly 4, and the pressing member 6 is pressed against the waterproof and breathable membrane 2. Specifically, the pressing member 6 is also located within the pressing cavity 122 and is tightly pressed against the waterproof and breathable membrane 2 in a sealed manner. This arrangement allows the pressing member 6 to press against the waterproof and breathable membrane 2 while also providing a clearance function, reducing interference between components.

[0037] The electronic device disclosed herein uses the pressing component 6 to press the waterproof and breathable membrane 2, which can improve the stability of the waterproof and breathable membrane 2 when it is attached to the support plate 12, so that the waterproof and breathable membrane 2 can withstand the impact of liquid with higher pressure, thereby improving the waterproof and dustproof performance of the electronic device and enabling the electronic device to meet the IP69K waterproof and dustproof requirements.

[0038] Along the thickness direction of the middle frame 1, the projection of the press-fit component 6 avoids the projection of the air hole 121, so that the gas passing through the air hole 121 can pass through the press-fit component 6 to achieve the balance of air pressure inside and outside the middle frame 1.

[0039] The pressing component 6 is a rubber ring, and it is arranged around the air hole 121 to improve the stability of the waterproof and breathable membrane 2. The pressing component 6 continuously presses against the waterproof and breathable membrane 2 along its circumference. Specifically, the surface of the pressing component 6 in contact with the waterproof and breathable membrane 2 forms a closed circle. This arrangement further improves the stability of the waterproof and breathable membrane 2 in adhering to the support plate 12. The pressing component 6 is a silicone ring or a rubber ring.

[0040] The circuit board is disposed on the carrier plate 12 and is located on the side of the carrier plate 12 opposite to the panel assembly 4. The circuit board includes a shield (not shown) that is pressed against the press member 6, thereby providing a clamping force when the press member 6 presses the waterproof and breathable membrane 2.

[0041] Further integration Figure 6As shown, the pressing component 6 includes a pressing component body 61, a pressing edge 62, and a vent 63. The pressing component body 61 is in contact with the waterproof and breathable membrane 2, and the pressing edge 62 protrudes from the pressing component body 61 toward the shielding cover, and the pressing edge 62 is in contact with the shielding cover. The pressing edge 62 is located at the middle of the pressing component body 61, and the pressing edge 62 is integrally formed with the pressing component body 61.

[0042] Vent hole 63 is located between the first end 621 and the last end 622 of the pressing edge 62, and vent hole 63 communicates with air hole 121 so that gas flowing through air hole 121 can flow from vent hole 63 to the side of the support plate 12 away from panel assembly 4. In order to allow gas to flow out of the pressing part 6 more quickly from air hole 121, multiple vent holes 63 can be provided and spaced apart along the circumference of the pressing part 6.

[0043] It should be noted that the technical solutions or features described in the above embodiments can be combined or complemented by each other without conflict. The scope of protection of this disclosure is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
