The housing 120 encloses the accommodating space 140, the housing 120 has an inner surface 1404 facing the accommodating space 140 and an outer surface 1402 facing away from the accommodating space 140, the housing 120 is provided with a through hole 102 extending from the outer surface 1402 to the inner surface 1404, and in some embodiments, the through hole 102 may be provided on the middle frame 121, i.e. the middle frame 121 may be used as a mounting portion, and in other embodiments, the rear cover 123 may be used as a mounting portion. The electronic device 100 further includes a waterproof and breathable membrane 108 and a guard 106, the waterproof and breathable membrane 108 being disposed within the receiving space 140 and being securable to an inner surface 1404 of the receiving housing 120. The waterproof breathable film 108 is a polymer waterproof material, and is generally composed of a nonwoven fabric and a polymer breathable film. The non-woven fabric mainly has the functions of enhancing the tensile force and the hydrostatic pressure and protecting the middle layer (breathable film), and the actual breathability is mainly achieved by the middle layer high polymer breathable film, such as TPU (Thermoplastic polyurethanes, thermoplastic polyurethane elastomer rubber) puffed film, PE (polyethylene) film, PET (Polyethylene terephthalate, polyester resin) film or polytetrafluoroethylene puffed film. Of course, the waterproof and breathable film 108 in the present application may not be limited to the above materials, as long as the solid film layer formed by the material having the waterproof and breathable functions in the general sense is within the protection scope of the present application. The waterproof and breathable membrane 108 may cover the through hole 102, that is, the waterproof and breathable membrane 108 completely covers the through hole 102, the waterproof and breathable membrane 108 may be adhered to the inner surface 1404 by spot gluing to ensure process stability and product reliability, and in other embodiments, the waterproof and breathable membrane 108 may be fixed to the inner surface 1404 by a pressing plate or other fixing members to achieve detachable connection, so as to facilitate detachment and replacement of the waterproof and breathable membrane 108.

The guard 106 is secured within the housing 130, i.e., the guard is secured between the inner and outer surfaces of the housing 130, in some embodiments the guard 106 may shield the through-hole 102, in other embodiments the guard 106 need not completely shield the through-hole, leaving a space between the guard 106 and the through-hole 102, which also serves to protect the waterproof breathable membrane 108 to some extent. Referring to fig. 1, the guard 106 shields the through-hole 102, i.e., in the axial direction of the through-hole 102, the guard 106 covers the through-hole 102. The material of the guard 106 may be metal, PET (Polyethylene terephthalate, dacron resin), etc., further, referring to fig. 6, the guard 106 may be generally rectangular and rounded at right angle transitions for ease of assembly, and in other embodiments, the guard 106 may be circular, oval, triangular, pentagonal, etc. The fact that the shield 106 is fixed to the housing 120 means that the shield 106 does not protrude from the inner and outer surfaces of the housing 120, i.e., the shield 106 is disposed between the inner surface 1404 and the outer surface 1402, the shield 106 may be disposed at a distance from the waterproof breathable membrane 108 in the axial direction of the through-hole 102, and in other embodiments, the surface of the shield 106 and the inner surface 1404 are substantially in the same plane, and thus may be bonded to the waterproof breathable membrane 108. The guard 106 may be injection molded with the housing 120, the guard 106 may be inserted into the housing 120 by Insert Molding, or the guard 106 may be fixed in the housing 120 by welding or gluing the guard 106 into the through hole 102.

The protecting member 106 may be provided with one or more air holes 1062, and the air holes 1062 may be connected to the through holes 102, so that external air can enter the accommodating space 140 through the through holes 102 and the waterproof and breathable film 108 to balance the internal and external air pressure of the electronic device 100. In embodiments where the shield 106 is metal, the vent 1062 may be formed by a metal etching process, and in other embodiments, the shield 106 may be formed by a mechanical punching, injection molding, or the like process. The vent 1062 may have a diameter of between 0.5mm and 3mm, and in some embodiments, the vent 1062 may have a diameter of 3mm to achieve a greater air flow rate and thus a faster air pressure balance within the electronic device 100.

In some embodiments, referring to fig. 4 and 6, the ventilation holes 1062 on the guard 106 may be arranged in the middle of the guard 106, for example, in a nine-grid form as in fig. 6, and of course, the arrangement of the ventilation holes 1062 may be varied, for example, circular, ring-shaped, polygonal, etc. The arrangement of the vent holes 1062 in the center of the guard 106 may facilitate communication between one or more vent holes 1062 and the through hole 102, reducing the size of the through hole 102, i.e., the through hole 102 may be made smaller. When the ventilation holes 1062 are arranged in the center of the protector 106, the ventilation holes 1062 are all located within the projection range of the through holes 102 on the protector 106. Of course, in other embodiments, not all of the vent 1062 may be in communication with the through-hole 102, and a portion of the vent 1062 may be covered by the housing 120.

In some embodiments, the functional module 104 may be disposed in the accommodating space 140, and in some embodiments, the functional module 104 may include a module support 1044 and an electroacoustic device 1042, where the electroacoustic device 1042 may be a microphone, a speaker, a receiver, or the like, which converts acoustic signals and electrical signals into each other. The functional module 104 may be secured within the receiving space 140 by a module support 1044. In some embodiments, the functional module 104 may abut the waterproof and breathable membrane 108 to further increase the mounting strength of the waterproof and breathable membrane 108. The electroacoustic device 1042 can be provided with a sound channel, the sound channel can be covered by the waterproof and breathable film 108, sound can be transmitted to the outside through the waterproof and breathable film and transmitted to the electroacoustic device 1042 through the through hole 102, so as to play a role of waterproof and breathable. In other embodiments, the electroacoustic device 1042 may be other components, such as a motor, a barometer, a battery, a fingerprint module, etc., which also has a waterproof effect due to the contact with the waterproof and breathable film 108.

In the assembly process of the electronic device 100, the protection piece 106 may be injection molded with the housing 120, or the protection piece 106 may be embedded in the middle of the housing 120 by Insert Molding (Insert Molding), or the protection piece 106 may be embedded in the through hole 102 with a larger aperture by welding or gluing, so as to fix the protection piece 106 in the housing 120. Such that the guard 106 is secured within the housing 120 and then the waterproof, breathable membrane 108 is secured to the inner surface 1404 of the housing 120, covering the through-hole 102. Compared with the scheme that the protective piece 106 and the waterproof breathable film 108 are jointly installed after being adhered, the assembly mode is short in assembly size chain and high in assembly precision, the damage risk of the waterproof breathable film 108 in the assembly process is reduced, and the reliability and the yield of products are improved.

When the housing 120, the waterproof and breathable film 108 and the protective member 106 are applied to the electronic device 100 and the wearable device 10, since the housing 120 is provided with the through hole 102, the through hole 102 on the housing 120 is communicated with the ventilation hole 1062 and covered by the waterproof and breathable film 108, and external air can enter the accommodating space 140 to balance the internal and external air pressure and play a role of waterproofing. Meanwhile, since the protecting piece 106 is fixed in the casing 120, the protecting piece 106 at least partially shields the through hole, and an external hard object can be shielded by the protecting piece 106 after entering the through hole, and then the waterproof breathable film 108 can not be touched, so that the waterproof breathable film 108 is protected, and the possibility that the waterproof breathable film 108 is damaged is reduced. Meanwhile, since the protecting piece 106 is fixed on the shell, the protecting piece 106 does not need to occupy the internal space of the electronic equipment 100, the protecting piece 106 and the waterproof and breathable film 108 are arranged separately, the assembly is more flexible, the installing can be more stable due to the fact that the protecting piece 106 is embedded in the shell 120, and the protecting effect is better. The waterproof breathable film 108 is attached to the inner surface 1024, and the installation mode is flexible and various due to the fact that the installation plane is smooth and the sealing effect is better.

Referring to fig. 4, 5, 7 and 8, the through hole 102 may include a first sub-hole 1022 and a second sub-hole 1024, wherein the first sub-hole 1022 communicates with the outer surface 1402 of the housing 120, and the second sub-hole 1024 communicates with the inner surface 1404 of the housing 120. In some embodiments, referring to fig. 4 and 5, the housing 120 may include an outer housing 122 and an inner housing 124, a first sub-aperture 1022 may be formed in the outer housing 122, a second sub-aperture 1024 may be formed in the inner housing 124, and the outer housing 122 may serve as a first mounting portion, the inner housing 124 may serve as a second mounting portion, and the first sub-aperture 1022 and the second sub-aperture 1024 may communicate and form a through-hole 102 through the inner and outer surfaces of the housing 120. In other embodiments, referring to fig. 7, the housing 120 may be integrated, the through hole 102 may be divided into a first sub-hole 1022 and a second sub-hole 1024 by the guard 106, where a housing portion (a portion divided by a dotted line) where the first sub-hole 1022 is located may be used as the first mounting portion 126, a housing portion (another portion divided by a dotted line) where the second sub-hole 1024 is located may be used as the second mounting portion 128, the first sub-hole 1022 and the second sub-hole 1024 may be communicated through the ventilation hole 1062, and of course, referring to fig. 8, the through hole 120 may be divided into the first sub-hole 1022 and the second sub-hole 1024 by the through hole 120 according to a hole size, a processing manner of the through hole 120, or the like, and the guard 106 may be located in the first sub-hole 1022 or the second sub-hole 1024 instead of the first sub-hole 1022 or the second sub-hole 1024.

In some embodiments, the first sub-aperture 1022 may have a different aperture than the second sub-aperture 1024, and further referring to fig. 4 and 7, the aperture of the second sub-aperture 1024 may be larger than the aperture of the first sub-aperture 1022. Because the first sub-holes 1022 communicate with the outer surface, the first sub-holes 1022 may be made smaller in order to reduce the likelihood of hard objects entering the through-holes 120. The second sub-aperture 1024 communicates with the inner surface 1404. The large aperture of the second sub-aperture 1024 allows for greater air flow and faster air pressure balance between the inside and outside of the electronic device 100. Of course, in other embodiments, the apertures of the first and second sub-apertures 1022 and 1024 may be set to be substantially uniform for ease of processing.

In some embodiments, referring to fig. 4 and 5, the housing 120 may be divided into an outer housing 122 and an inner housing 124, and the guard 106 may be secured between the outer housing 122 and the inner housing 124. During the forming process, the shield may be glued or welded to the outer shell 122 prior to assembly of the inner shell 124. Further, the outer shell 122 may be made of metal, the inner shell 124 may be made of plastic, the outer shell 122 is integrally processed, the protecting member 106 is adhered or welded to the outer shell 122 and covers the through hole 102, and the plastic part (i.e. the inner shell 124) is injection molded on the outer shell 122 by Insert Molding. Of course, the outer shell 122 and the inner shell 124 may be made of plastic, the outer shell 122 is processed first, the protecting member 106 is adhered or welded to the outer shell 122 and covers the through hole 102, and the inner shell 124 is injection molded to the outer shell 122 by a two-shot injection molding (Comolding) method. The outer shell 122 and the inner shell 124 may also be made of metal, and after the outer shell 122 is machined and the protection member 106 is installed, the inner shell 124 is mated with the outer shell 122 by an interference fit manner to form the housing 120. The protection member 106 is fixed between the outer case 122 and the inner case 124, which facilitates the arrangement of the protection member 106 and the formation of the case 120, and ensures the waterproof effect of the electronic device 100 while the protection member 106 does not occupy the inner space of the electronic device 100. Of course, referring to fig. 7, in an embodiment where the housing 120 is integrally formed, the housing portion where the first sub-hole 1022 is located may be used as the first mounting portion 126, the housing portion where the second sub-hole 1024 is located may be used as the second mounting portion 128, the protection member 106 is located between the first sub-hole 1022 and the second sub-hole 1024, and the first sub-hole 1022 and the second sub-hole 1024 may be distributed on two sides of the protection member 106. In some embodiments, referring to fig. 8 and 9, the guard 106 may be secured within the second sub-aperture 1024. Specifically, the housing 120 has a thickness direction (a direction in which the inner surface faces the outer surface), the projection of the guard 106 in the vertical thickness direction is completely located in the projection area of the second sub-hole 1024 in the vertical thickness direction, the ventilation hole 1062 provided in the guard 106 of the second sub-hole 1024 communicates with the second sub-hole 1024, and the guard 1024 may be spaced from the first mounting portion 126 or may be attached to the first mounting portion 126. Further, in embodiments where the housing 120 is divided into the inner housing 124 and the outer housing 122, the guard 106 may be injection molded with the inner housing 124, and thus, in embodiments where the second sub-aperture 1024 has a larger aperture than the first sub-aperture 1022, the guard 106 may shield the first sub-aperture 1022, and in embodiments where the housing 120 is integrally molded, the guard 106 may also be injection molded with the housing 120. The guard 106 may have a larger size than the aperture of the second sub-aperture 1024, e.g., the guard 106 may have a larger cross-sectional area than the second sub-aperture 1024, and thus the aperture of the second sub-aperture 1024 need not be larger than the aperture of the first sub-aperture 1022, and the guard may also be capable of shielding the first sub-aperture 1022. Because the aperture of the second sub-aperture 1024 is larger than that of the first sub-aperture 1022, the fixing of the protection member 106 to the second sub-aperture 1024 can reduce the difficulty of assembling or forming the protection member 106 and increase the production yield. In other embodiments, the guard 106 may also be secured within the first sub-aperture 1022.

Referring to fig. 9, the guard 106 is fixed in the second sub-hole 1024, and may not have to be larger than the second sub-hole 1024, i.e., the cross-sectional area of the guard 106 may be smaller than or equal to the cross-sectional area of the second sub-hole 1024, in such an embodiment, the guard 106 may be completely received in the second sub-hole 1024 and attached to the first mounting portion 126 where the first sub-hole 1022 is located, and the cross-sectional area of the guard 106 may be larger than the cross-sectional area of the first sub-hole 1022 to shield the first sub-hole 1022. In other embodiments, the aperture of the first sub-aperture 1022 is greater than the aperture of the second sub-aperture 1024, at which point the guard 106 may be secured within the first sub-aperture 1022. Further, the guard 106 may be attached to the second mounting portion 128 where the second sub-hole 1024 is located.
