The electronic device 100 further includes a waterproof air-permeable membrane 108 and a shielding member 106, wherein the waterproof air-permeable membrane 108 is disposed in the accommodating space 140 and can be fixed on the inner surface 1404 of the accommodating housing 120. The waterproof breathable film 108 is a polymer waterproof material, and generally comprises a nonwoven fabric and a polymer breathable film. The non-woven fabric mainly has the functions of enhancing tension and hydrostatic pressure and protecting the middle layer (breathable film), and the real ventilation is mainly realized by the middle layer macromolecular breathable film, such as TPU (Thermoplastic polyurethane elastomers, rubbers) expanded film, PE (Polyethylene) film, PET (Polyethylene terephthalate, polyester resin) film or polytetrafluoroethylene expanded film. Of course, the waterproof breathable film 108 in the present application is not 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 ventilated membrane 108 can cover the through hole 102, namely the waterproof ventilated membrane 108 completely covers the through hole 102, and the waterproof ventilated membrane 108 can be adhered to the inner surface 1404 through glue dispensing so as to ensure the stability of the process and the reliability of the product, and in other embodiments, the waterproof ventilated membrane 108 can also be fixed to the inner surface 1404 through a pressing plate or other fixing pieces, so that the detachable connection is realized, and the detachment and replacement of the waterproof ventilated membrane 108 are facilitated.

The shielding member 106 is fixed in the housing 130, i.e. the shielding member is fixed between the inner and outer surfaces of the housing 130, in some embodiments, the shielding member 106 may block the through hole 102, in other embodiments, the shielding member 106 does not need to completely block the through hole, and a gap is left between the shielding member 106 and the through hole 102, which also can protect the waterproof and breathable membrane 108 to some extent. Referring to fig. 1, the shield 106 blocks the through hole 102, i.e., the shield 106 covers the through hole 102 in the axial direction of the through hole 102.

The shielding member 106 may be formed by injection Molding together with the housing 120, or by Insert Molding (Insert Molding) to Insert the shielding member 106 into the housing 120, or by welding or gluing to embed the shielding member 106 into the through hole 102 to fix the shielding member 106 in the housing 120.

The protection component 106 may have one or two or more air holes 1062, and the air holes 1062 are communicated with the through hole 102, so that the external air can enter the accommodating space 140 through the through hole 102 and the waterproof air-permeable film 108 to balance the internal and external air pressures of the electronic device 100. In embodiments where the guard 106 is metal, the vent 1062 may be formed by a metal etching process, and in other embodiments, the guard 106 may be formed by mechanical punching, injection molding, or the like. The diameter of the vent 1062 may be between 0.5mm and 3mm, and in some embodiments, the diameter of the vent 1062 may be 3mm to achieve greater air flow to more quickly equalize the air pressure inside the electronic device 100.

In some embodiments, referring to fig. 4 and 6, the ventilation holes 1062 on the protection member 106 may be arranged in the middle of the protection member 106, for example, forming a squared figure as in fig. 6, of course, the arrangement of the ventilation holes 1062 may be various, for example, in a circular shape, a ring shape, a polygonal shape, etc. The arrangement of the vent 1062 in the center of the protection member 106 facilitates the communication between one or two or more vent 1062 and the through hole 102, thereby reducing the size requirement of the through hole 102, i.e., the through hole 102 can be made smaller. When the air holes 1062 are arranged in the center of the protection member 106, the air holes 1062 are all located within the projection range of the through holes 102 on the protection member 106. Of course, in other embodiments, the air holes 1062 may not be all communicated with the through holes 102, and part of the air holes 1062 may be covered by the housing 120.

In some embodiments, the functional module 104 may be disposed in the accommodating space 140, in some embodiments, the functional module 104 may include a module support 1044 and an electroacoustic device 1042, and the electroacoustic device 1042 may be a device that converts an acoustic signal and an electrical signal into each other, such as a microphone, a speaker, or a receiver. The functional module 104 may be fixed in the accommodating space 140 by a module support 1044, and in some embodiments, the functional module 104 may abut against the waterproof breathable film 108, so as to further increase the installation strength of the waterproof breathable film 108. The electroacoustic device 1042 can be provided with a sound channel, the sound channel can be covered by the waterproof breathable film 108, sound can be transmitted to the outside through the waterproof breathable film and the through hole 102, and external sound can also be transmitted to the electroacoustic device 1042 through the waterproof breathable film through the through hole 102, so that the waterproof and sound-transmitting effects are achieved. In other embodiments, the electroacoustic device 1042 may also be another component, such as a motor, a barometer, a battery, a fingerprint module, etc., which can also achieve the waterproof effect due to the abutting waterproof permeable membrane 108.

In the assembling process of the electronic device 100, the shielding element 106 and the housing 120 may be injection molded, the shielding element 106 may be embedded in the housing 120 by Insert Molding (Insert Molding), and the shielding element 106 may be embedded in the through hole 102 with a larger aperture by welding or gluing to fix the shielding element 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 protection part 106 and the waterproof breathable film 108 are installed together after being bonded, the assembling size chain of the assembling mode is short, the matching precision is high, the damage risk of the waterproof breathable film 108 in the assembling process is reduced, and the reliability and yield of the product are improved.

When the housing 120, the waterproof breathable film 108 and the protection part 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 vent hole 1062 and covered by the waterproof breathable film 108, external air can enter the accommodating space 140 to balance internal and external air pressure, and a waterproof function is achieved. Meanwhile, as the protection part 106 is fixed in the housing 120, the through hole is at least partially shielded by the protection part 106, and an external hard object can be shielded by the protection part 106 after entering the through hole, and further cannot touch the waterproof breathable film 108, so that the effect of protecting the waterproof breathable film 108 is achieved, and the possibility that the waterproof breathable film 108 is damaged is reduced. Meanwhile, since the protection member 106 is fixed to the housing, the protection member 106 does not need to occupy the internal space of the electronic device 100, the protection member 106 and the waterproof breathable film 108 are separately disposed, so that the assembly is more flexible, and the protection member 106 is embedded in the housing 120, so that the installation is more stable, and the protection effect is better. Waterproof ventilated membrane 108 pastes and locates internal surface 1024, because the mounting surface is level and smooth, and sealed effect is better, and the mode of installation is also nimble more various.

Referring also to fig. 4, 5, 7 and 8, the through-hole 102 may include a first sub-hole 1022 and a second sub-hole 1024, the first sub-hole 1022 communicating with the outer surface 1402 of the housing 120, the second sub-hole 1024 communicating 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 shell 122 and an inner shell 124, the first sub-hole 1022 may be opened in the outer shell 122, the second sub-hole 1024 may be opened in the inner shell 124, in which case the outer shell 122 may serve as a first mounting portion, the inner shell 124 may serve as a second mounting portion, and the first sub-hole 1022 and the second sub-hole 1024 communicate and form the through hole 102 penetrating 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 protection component 106, a housing portion (a portion divided by a dotted line) where the first sub-hole 1022 is located may serve 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 serve as the second mounting portion 128, and the first sub-hole 1022 and the second sub-hole 1024 may communicate through the ventilation hole 1062, and referring to fig. 8, the through hole 120 may be divided into the first sub-hole 1022 and the second sub-hole 1024 according to the size of the hole, the processing manner of the through hole 120, and the like, and the protection component 106 may be located not between the first sub-hole 1022 and the second sub-hole 1024 but in the first sub-hole 1022 or the second sub-hole 1024.

In some embodiments, the first sub-aperture 1022 may have a different aperture size than the second sub-aperture 1024, and further, referring to fig. 4 and 7, the aperture size of the second sub-aperture 1024 may be larger than the aperture size of the first sub-aperture 1022. Since the first sub-apertures 1022 communicate with the outer surface, the first sub-apertures 1022 may be smaller in order to reduce the chance of hard objects entering the through-hole 120. The second sub-aperture 1024 communicates with the inner surface 1404, and the large aperture of the second sub-aperture 1024 allows for a larger airflow rate, which allows the inside and outside of the electronic device 100 to more quickly reach a pressure equilibrium. Of course, in other embodiments, the first sub-holes 1022 and the second sub-holes 1024 may have substantially the same aperture for the convenience of processing.

In some embodiments, referring to fig. 4 and 5, the housing 120 may be divided into an outer shell 122 and an inner shell 124, and the shield 106 may be secured between the outer shell 122 and the inner shell 124. During the forming process, the shielding member may be bonded or welded to the outer shell 122 before the inner shell 124 is assembled. 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 formed, the shielding member 106 is adhered or welded to the outer shell 122 and covers the through hole 102, and then the plastic portion (i.e., the inner shell 124) is injection molded on the outer shell 122 by Insert Molding (Insert Molding). Of course, the outer shell 122 and the inner shell 124 may be made of plastic, and the outer shell 122 is also manufactured, the shielding member 106 is adhered or welded to the outer shell 122 and covers the through hole 102, and then the inner shell 124 is injection molded on the outer shell 122 by a second injection molding (assembling) method. The outer shell 122 and the inner shell 124 may also be made of metal, and after the outer shell 122 is formed and the shielding element 106 is installed, the inner shell 124 and the outer shell 122 are fitted to form the housing 120 by interference fit. The structure of the shielding element 106 fixed between the outer casing 122 and the inner casing 124 facilitates the arrangement of the shielding element 106 and the formation of the casing 120, and ensures the waterproof effect of the electronic device 100 while the shielding element 106 does not occupy the internal space of the electronic device 100. Of course, referring to fig. 7, in the embodiment where the housing 120 is integrally formed, the housing portion where the first sub-aperture 1022 is located may be used as the first mounting portion 126, the housing portion where the second sub-aperture 1024 is located may be used as the second mounting portion 128, the protection member 106 is located between the first sub-aperture 1022 and the second sub-aperture 1024, and the first sub-aperture 1022 and the second sub-aperture 1024 may be distributed on two sides of the protection member 106. In some embodiments, referring to fig. 8 and 9, guard 106 may be secured within 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 protector 106 in the vertical thickness direction is completely located in the projection area in the vertical thickness direction of the second sub-hole 1024, the air hole 1062 provided in the protector 106 in the second sub-hole 1024 communicates with the second sub-hole 1024, and the protector 1024 may be provided at a distance from the first mounting part 126 or may be attached to the first mounting part 126. Further, in an embodiment where the housing 120 is divided into the inner shell 124 and the outer shell 122, the shielding element 106 may be injection molded together with the inner shell 124, so that in an embodiment where the aperture of the second sub-aperture 1024 is larger than the aperture of the first sub-aperture 1022, the shielding element 106 may block the first sub-aperture 1022, and in an embodiment where the housing 120 is integrally molded, the shielding element 106 may be injection molded together with the housing 120. The shielding member 106 may have a larger size than the aperture of the second sub-aperture 1024, for example, the cross-sectional area of the shielding member 106 is larger than the cross-sectional area of the second sub-aperture 1024, and thus, the aperture of the second sub-aperture 1024 is not necessarily larger than the aperture of the first sub-aperture 1022, and the shielding member can also shield the first sub-aperture 1022. Since the aperture of the second sub-hole 1024 is larger than that of the first sub-hole 1022, the protection component 106 can be fixed to the second sub-hole 1024, so that the assembly or molding difficulty of the protection component 106 can be reduced, and the production yield can be increased.
