Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more particularly to a housing and an electronic device. Background Technology

[0002] With the continuous development of acoustic technology, people's demand for the low-frequency acoustic performance of electronic devices is gradually increasing.

[0003] Related technology provides an electronic device, including a housing and a speaker disposed within the housing, wherein the rear acoustic cavity of the speaker is connected to the internal space of the housing, so that the internal space of the housing can be equivalent to the rear acoustic cavity of the speaker, thereby improving the low-frequency acoustic performance of the speaker.

[0004] However, the sound energy carried by the sound waves generated by the speaker is transmitted from inside the electronic device's casing to the casing, causing the casing to vibrate significantly. Utility Model Content

[0005] This application provides a housing and an electronic device to reduce body vibration.

[0006] In a first aspect, embodiments of this application provide a housing, comprising:

[0007] The main body has a cavity inside and a first through hole on the main body, which connects the cavity to the outside of the main body.

[0008] A support member is disposed within the receiving cavity, located on the periphery of the first through hole, and communicating with the first through hole;

[0009] A waterproof and acoustically permeable membrane is disposed on a support member. The membrane is configured to transform a portion of the original sound waves within the receiving cavity into direct sound waves that are transmitted to the outside of the body through a first through-hole. At least one of the support member and the receiving cavity located within the area enclosed by the support member is configured to block the original sound waves entering the support member through the waterproof and acoustically permeable membrane, thereby forming diffracted sound waves that can be transmitted to the outside of the body through the first through-hole.

[0010] In one possible implementation, the support member has at least one second through hole, the second through hole connecting the first through hole and the receiving cavity, the second through hole is covered by a waterproof and sound-permeable membrane, and the inner wall of the second through hole is used to block the original sound waves entering the support member through the waterproof and sound-permeable membrane.

[0011] In one possible implementation, a second via is provided, which is coaxially arranged with the first via and surrounds the periphery of the first via.

[0012] In one possible implementation, both the second via and the first via are circular holes;

[0013] The ratio of the diameter of the second via to the diameter of the first via is 1.2 to 2.

[0014] In one possible implementation, at least two second vias are provided, with one end of at least one second via located within the area enclosed by the first via, and the projection of the other end of the second via toward the first via located outside the area enclosed by the first via; the projections of both ends of at least one second via toward the first via located within the area enclosed by the first via.

[0015] In one possible implementation, the diameter of the second through-hole gradually decreases along the direction from the waterproof and sound-permeable membrane to the first through-hole.

[0016] In one possible implementation, the support is bonded, screwed, or welded to the body.

[0017] In one possible implementation, the waterproof and sound-permeable membrane is bonded or pressed together with the support.

[0018] In one possible implementation, the housing further includes an adhesive layer, through which the waterproof and sound-permeable membrane is bonded to the support.

[0019] The adhesive layer is a hot melt adhesive layer, a pressure-sensitive adhesive layer, or a photosensitive adhesive layer.

[0020] In one possible implementation, the waterproof and sound-permeable membrane is a polyurethane film, a polyethylene film, a polypropylene film, a polyester film, or a polyimide film.

[0021] In one possible implementation, the body includes a mid-frame and a housing connected to the mid-frame, with a first through-hole provided on the mid-frame or the housing.

[0022] Secondly, embodiments of this application provide an electronic device, including any of the housings provided in the first aspect and an acoustic element disposed within the housing.

[0023] The housing and electronic device provided in this application embodiment include a body with a cavity for accommodating internal components; a first through hole on the body connecting the cavity to the outside of the body to form a sound wave transmission channel; and a support member disposed within the cavity and communicating with the first through hole, such that the support member and the first through hole together form a sound wave transmission channel.

[0024] By placing a support member around the first through-hole and providing a waterproof and sound-permeable membrane on the support member, the membrane effectively isolates the cavity from the support member, preventing water, dust, and other impurities from entering the cavity through the support member. The membrane also allows the original sound waves within the cavity to be diverted into direct sound waves that are transmitted through the first through-hole to the outside of the body. Furthermore, at least one of the support member and the cavity within the area enclosed by the support member can block the original sound waves entering the support member through the waterproof and sound-permeable membrane, thus forming diffracted sound waves that can be transmitted through the first through-hole to the outside of the body. Therefore, compared to related technologies, the improved shell in this application allows both the diffracted and direct sound waves to be transmitted through the first through-hole to the outside of the body, reducing the accumulation of sound energy within the cavity and consequently reducing the amount of sound energy transmitted to the body, thereby lowering the vibration of the body.

[0025] In summary, the housing provided in this application embodiment, by setting a support member around the first through hole and placing the waterproof and sound-permeable membrane on the support member, allows the waterproof and sound-permeable membrane to have a larger sound-permeable area. Compared to directly covering the first through hole with the waterproof and sound-permeable membrane, the waterproof and sound-permeable membrane provided in this application embodiment has a larger sound-permeable area, allowing more sound waves to pass through it. This results in more sound waves being transmitted to the outside of the body, allowing more sound energy to be released from the cavity to the outside of the body, further reducing the accumulation of sound energy within the cavity and thus further reducing the vibration of the body.

[0026] Furthermore, compared to setting a larger first through hole on the main body and then directly covering the waterproof and sound-permeable membrane on the first through hole, the housing provided in this application embodiment can increase the amount of sound waves transmitted to the outside of the main body without increasing the size of the first through hole by setting a support member, thus without reducing the structural strength of the main body.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In the description of the embodiments of this application, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships (if present), are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Where there is no conflict, embodiments of this application and the various features thereof can be combined with each other, all of which are within the scope of protection of this application.

[0043] This application provides an electronic device. Figure 1 This is a schematic diagram of the electronic device.

[0044] Specifically, please refer to Figure 1 The electronic device includes a housing 10 and an acoustic element 20 disposed within the housing 10.

[0045] The acoustic element 20 is used to output sound, and the housing 10 is used to house and protect the internal components of the electronic device (such as the acoustic element 20).

[0046] In some embodiments, please continue reading Figure 1 The electronic device also includes a motherboard 30, which is disposed inside the housing 10, and the acoustic element 20 is electrically connected to the motherboard 30.

[0047] The motherboard 30 serves as the core control element of the electronic device, used to control the operation of other electronic components inside the electronic device (such as acoustic components 20).

[0048] In other embodiments, the acoustic element 20 is a loudspeaker or a receiver. A loudspeaker is a device that converts electrical signals into sound waves for external sound output, and a receiver is a miniaturized sound-generating element designed for close-range listening.

[0049] In some other embodiments, the rear acoustic cavity of the acoustic element 20 (not shown) is in communication with the internal space of the housing 10.

[0050] In this embodiment, by connecting the rear acoustic cavity of the acoustic element 20 with the internal space of the housing 10, the internal space of the housing 10 can be equivalent to the rear acoustic cavity of the acoustic element 20, thereby effectively expanding the volume of the rear acoustic cavity of the acoustic element 20, and thus making the low-frequency acoustic performance of the acoustic element 20 better.

[0051] It should be noted that this embodiment does not limit the specific type of electronic device; it can be selected according to needs. For example, electronic devices include mobile phones, laptops, desktop computers, headphones, speakers, servers, wearable devices, home appliances, office equipment, gaming and entertainment devices, health and medical devices, industrial equipment, or network equipment, etc. For some examples, please refer to... Figure 1 When the electronic device is a mobile phone, the housing 10 may include the mid-frame 130 and the outer shell 140 of the mobile phone, and the acoustic element 20 may be a speaker disposed within the space enclosed by the mid-frame 130 and the outer shell 140. In other examples, when the electronic device is a laptop computer, the housing 10 may be the display shell or the chassis shell of the laptop computer, and the acoustic element 20 may be a speaker disposed within the display shell or the chassis shell.

[0052] Understandable, Figure 1 The diagram only schematically illustrates some of the components included in the electronic device; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, electronic devices may also include, compared to Figure 1 More or fewer parts.

[0053] With the continuous development of acoustic technology, people's demand for the low-frequency acoustic performance of electronic devices is gradually increasing.

[0054] Related technology provides an electronic device, including a housing and a speaker disposed within the housing, wherein the rear acoustic cavity of the speaker is connected to the internal space of the housing, so that the internal space of the housing can be equivalent to the rear acoustic cavity of the speaker, thereby improving the low-frequency acoustic performance of the speaker.

[0055] However, the sound energy carried by the sound waves generated by the speaker is transmitted from inside the electronic device's casing to the casing, causing the casing to vibrate significantly.

[0056] Related technologies also provide an electronic device including a housing and a waterproof and acoustically permeable membrane assembly. The housing has an opening, and the waterproof and acoustically permeable membrane assembly covers the opening. The waterproof and acoustically permeable membrane assembly not only allows sound waves to pass through so that the sound energy carried by the sound waves is released to the outside of the housing, thereby reducing the vibration of the housing, but also prevents water and other impurities from entering the housing from the outside through the opening.

[0057] However, with the aforementioned electronic equipment, the amount of sound waves transmitted from the inside of the housing to the outside of the housing is relatively small, resulting in less sound energy being transmitted from the inside of the housing to the outside of the housing, which in turn leads to poor vibration damping performance of the housing.

[0058] For the above technical issues, please refer to [link / reference needed]. Figure 1 This application embodiment also provides a housing 10, including: a body 100, the body 100 having a receiving cavity 120, the body 100 having a first through hole 110, the first through hole 110 communicating with the receiving cavity 120 and the outside of the body 100; a support member 200, the support member 200 being disposed within the receiving cavity 120, the support member being located on the periphery of the first through hole 110, and the support member 200 communicating with the first through hole 110; and a waterproof and sound-permeable membrane 300, the waterproof and sound-permeable membrane 300 being disposed on... On the support member 200, the waterproof and sound-permeable membrane 300 is configured to transform a portion of the original sound waves within the receiving cavity 120 into direct sound waves that are transmitted to the outside of the body 100 via the first through hole 110; at least one of the support member 200 and the receiving cavity 120 located within the area enclosed by the support member 200 is configured to block the original sound waves entering the support member 200 via the waterproof and sound-permeable membrane 300, so as to form diffracted sound waves that can be transmitted to the outside of the body 100 via the first through hole 110.

[0059] The housing 10 provided in this embodiment of the application has a body 100, which has a receiving cavity 120. The receiving cavity 120 can be used to accommodate internal components of the housing 10 (such as the support member 200 and the waterproof and sound-permeable membrane 300). A first through hole 110 is provided on the body 100, which connects the receiving cavity 120 with the outside of the body 100 to form a sound wave transmission channel. A support member 200 is provided, which is disposed in the receiving cavity 120 and communicates with the first through hole 110, so that the support member 200 and the first through hole 110 together form a sound wave transmission channel.

[0060] By setting the support member 200 around the first through hole 110 and by setting a waterproof and sound-permeable membrane 300 on the support member 200, the support member 200 can support the waterproof and sound-permeable membrane 300, so that the waterproof and sound-permeable membrane 300 can isolate the receiving cavity 120 from the support member 200, so as to prevent water, dust and other impurities from entering the receiving cavity 120 through the support member 200. The waterproof and sound-permeable membrane 300 can be used to convert part of the original sound waves in the receiving cavity 120 into direct sound waves that are transmitted to the outside of the body 100 through the first through hole 110. It also makes at least one of the support member 200 and the receiving cavity 120 located in the area enclosed by the support member 200 usable to block the original sound waves that enter the support member 200 through the waterproof and sound-permeable membrane 300, so as to form diffracted sound waves that can be transmitted to the outside of the body 100 through the first through hole 110.

[0061] Therefore, compared with related technologies, the acoustic energy carried by the diffracted sound waves and direct sound waves formed by the shell 10 of the present application embodiment can be transmitted to the outside of the body 100 through the first through hole 110, thereby reducing the amount of acoustic energy accumulation in the receiving cavity 120, resulting in less acoustic energy being transmitted to the body 100, and thus reducing the vibration of the body 100.

[0062] In summary, the housing 10 provided in this embodiment of the application, by providing a support member 200 disposed around the first through hole 110, and the waterproof and sound-permeable membrane 300 disposed on the support member 200, allows the waterproof and sound-permeable membrane 300 to have a larger sound-permeable area. Compared to related technologies that directly cover the opening with the waterproof and sound-permeable membrane assembly, the waterproof and sound-permeable membrane 300 provided in this embodiment of the application has a larger sound-permeable area, allowing more sound waves to pass through it. This results in more sound waves being transmitted to the outside of the body 100, allowing more sound energy to be released from the receiving cavity 120 to the outside of the body 100, further reducing the accumulation of sound energy within the receiving cavity 120, and thus further reducing the vibration of the body 100.

[0063] Furthermore, compared to setting a larger first through hole 110 on the body 100 and then directly covering the waterproof and sound-permeable membrane 300 on the first through hole 110, the housing 10 provided in this application embodiment can increase the amount of sound waves transmitted to the outside of the body 100 without increasing the size of the first through hole 110 by setting a support member 200, so as not to reduce the structural strength of the body 100.

[0064] It should be noted that the original sound waves within the cavity 120 include both low-frequency and high-frequency sound waves. Given that the dimensions of the support member 200 and the first through-hole 110 have a certain relationship with the wavelength of the original sound waves, according to the principle of wave diffraction, some low-frequency sound waves, after passing through the waterproof and sound-permeable membrane 300 and entering the support member 200, can contact the support member 200, or the cavity 120 located within the area enclosed by the support member 200 (i.e., the cavity 120 jointly enclosed by the support member 200 and the body 100), or simultaneously contact both the support member 200 and the cavity 120 located within the area enclosed by the support member 200. This causes at least one of the support member 200 and the body 100 to act as a barrier. After being blocked, the low-frequency sound waves will change their propagation direction, thereby forming diffracted sound waves that are transmitted to the outside of the body 100 through the first through-hole 110. It is understandable that the specific dimensions of the support 200 and the first through hole 110 can be set according to specific requirements, which will not be elaborated here, as long as diffracted sound waves and direct sound waves can be formed.

[0065] It should also be noted that this embodiment does not limit the specific method by which the waterproof sound-permeable membrane 300 transmits sound waves. The original sound waves can be transmitted through its micropores or through vibration. This embodiment does not limit the size of the waterproof sound-permeable membrane 300, as long as its effective sound-permeable area is larger than the effective sound-permeable area of ​​the waterproof sound-permeable membrane 300 directly disposed on the first through-hole 110.

[0066] The preferred technical solution of the housing 10 of this application embodiment is described below with reference to the accompanying drawings. Figure 2 for Figure 1 A schematic diagram of the connection between the first type of support member 200 and the body 100; Figure 3 for Figure 1 A schematic diagram of the connection between the second type of support member 200 and the body 100; Figure 4 for Figure 1 A schematic diagram of the connection between the third type of support member 200 and the main body 100; Figure 5 for Figure 1 A schematic diagram of the structure in which the waterproof and sound-permeable membrane 300 is connected to the support member 200 through the adhesive layer 400.

[0067] In some embodiments, please refer to Figures 2 to 4 The support member 200 has at least one second through hole 210, which connects the first through hole 110 and the receiving cavity 120. A waterproof and sound-permeable membrane 300 covers the second through hole 210, and the inner wall of the second through hole 210 is used to block the original sound waves entering the support member 200 through the waterproof and sound-permeable membrane 300.

[0068] In this embodiment, by providing a second through hole 210, which connects the first through hole 110 and the receiving cavity 120, and the waterproof and sound-permeable membrane 300 covering the second through hole 210, the original sound waves in the receiving cavity 120 first pass through the waterproof and sound-permeable membrane 300, then through the second through hole 210, and finally through the first through hole 110 to the outside of the body 100.

[0069] Specifically, one end of the second through hole 210 can be connected to the first through hole 110, and the waterproof and sound-permeable membrane 300 can cover the other end of the second through hole 210, so that the waterproof and sound-permeable membrane 300 can vibrate using the internal space of the second through hole 210 to achieve the transmission of the original sound waves.

[0070] The inner wall of the second through-hole 210 can be used directly to block the original sound waves entering the support member 200 through the waterproof and sound-permeable membrane 300, or it can be used together with the cavity wall of the receiving cavity 120 in the body 100 to block the original sound waves entering the support member 200 through the waterproof and sound-permeable membrane 300, so that some of the original sound waves change their propagation direction to form diffracted sound waves, which are then transmitted to the outside of the body 100 through the first through-hole 110. Furthermore, some of the original sound waves may not contact the inner wall of the second through-hole 210 and the cavity wall of the receiving cavity 120, but instead pass directly through the second through-hole 210 to form direct sound waves, which are then transmitted to the outside of the body 100 through the first through-hole 110.

[0071] Therefore, the acoustic energy carried by both the diffracted sound wave and the direct sound wave can be transmitted to the outside of the body 100 through the first through hole 110, which reduces the amount of acoustic energy accumulated in the receiving cavity 120, thereby reducing the amount of acoustic energy transmitted to the shell 10 and thus reducing the vibration of the body 100.

[0072] Furthermore, at least one second through-hole 210 can be disposed around the first through-hole 110. Since the waterproof and sound-permeable membrane 300 covers the second through-hole 210, the area of ​​the waterproof and sound-permeable membrane 300 that is not sealed is relatively large. Compared with related technologies that directly cover the opening with the waterproof and sound-permeable membrane assembly, the waterproof and sound-permeable membrane 300 provided in this application embodiment has a larger sound-permeable area (the larger the unsealed area, the larger the area where the waterproof and sound-permeable membrane 300 can transmit the original sound waves). More sound waves can pass through the waterproof and sound-permeable membrane 300, and more sound waves can be transmitted to the outside of the body 100. This allows more sound energy to be released from the receiving cavity 120 to the outside of the body 100, further reducing the accumulation of sound energy in the receiving cavity 120, and thus further reducing the vibration of the body 100.

[0073] For some specific implementation methods, please refer to Figure 2 and Figure 3A second via 210 is provided, which is coaxially arranged with the first via 110 and is arranged around the periphery of the first via 110.

[0074] In this embodiment, by coaxially arranging the second through-hole 210 with the first through-hole 110 and surrounding the first through-hole 110, the original sound wave passing through the waterproof sound-permeable membrane 300 can directly pass through the second through-hole 210 to form a direct sound wave, and can also be blocked by the inner wall of the second through-hole 210 to form a diffracted sound wave, thereby reducing the amount of sound energy accumulated in the receiving cavity 120 and reducing the vibration of the body 100; moreover, the waterproof sound-permeable membrane 300 that seals the second through-hole 210 is also surrounded around the first through-hole 110, thereby making the sound-permeable area of ​​the waterproof sound-permeable membrane 300 larger.

[0075] In summary, this embodiment simplifies the structure of the support member 200 by providing a single second through hole 210, making it easier to manufacture and process, and reducing production difficulty and cost. Furthermore, when manufacturing the support member 200 with a single second through hole 210, only the necessary edge support portions of the support member 200 need to be retained to support the waterproof and sound-permeable membrane 300 and the connecting body 100. The middle portion of the support member 200 can be used to create the second through hole 210. Therefore, the second through hole 210 can be designed to be relatively large, allowing more sound waves to pass through the waterproof and sound-permeable membrane 300.

[0076] In some examples, please refer to Figure 2 Both the second via 210 and the first via 110 are round holes.

[0077] In this example, by setting both the second through hole 210 and the first through hole 110 as round holes, not only is the structure of the body 100 and the support 200 simple and easy to manufacture, but the dimensions of the second through hole 210 and the first through hole 110 are also easy to control, which is beneficial to the transmission of sound waves.

[0078] Furthermore, the ratio of the diameter of the second via 210 to that of the first via 110 is 1.2 to 2.

[0079] Provided the size of the first through-hole 110 is within a suitable range, the larger the aforementioned ratio, the larger the diameter of the second through-hole 210, and the larger the sizes of the support member 200 and the waterproof and sound-permeable membrane 300 covering the second through-hole 210. This results in larger sizes for the support member 200 and the waterproof and sound-permeable membrane 300, leading to higher manufacturing costs and difficulties. Therefore, this example sets the ratio of the diameter of the second through-hole 210 to that of the first through-hole 110 to 1.2~2, allowing the housing provided in this example to improve the transmission of sound waves while maintaining relatively low manufacturing costs and difficulties.

[0080] It should be noted that the second via 210 can also be a hole of other shapes, such as Figure 3 The frustum-shaped aperture shown, with its inclined inner wall, can block the original sound waves passing through the waterproof and acoustically permeable membrane 300, thus forming diffracted sound waves. Furthermore, one end of the frustum-shaped second through-hole 210 can be matched and connected to the first through-hole 110, which not only facilitates the positioning of the support member 200 but also allows the original sound waves to be directly guided into the first through-hole 110 without contacting the body 100, thereby reducing the impact of the sound waves on the body 100.

[0081] In other embodiments, please refer to Figure 4 At least two second vias 210 are provided. One end of at least one second via 210 is located within the area enclosed by the first via 110, and the projection of the other end of the second via 210 toward the first via 110 is located outside the area enclosed by the first via 110. The projections of both ends of at least one second via 210 toward the first via 110 are located within the area enclosed by the first via 110.

[0082] By placing one end of at least one second through-hole 210 within the area enclosed by the first through-hole 110, and ensuring that the projection of the other end of the second through-hole 210 toward the first through-hole 110 lies outside the area enclosed by the first through-hole 110, the portion of the support member 200 corresponding to the body 100 (i.e., the portion of the support member 200 not corresponding to the first through-hole 110) includes not only the solid portion for supporting the waterproof and sound-permeable membrane 300, but also a channel for sound waves to pass through. Specifically, after the original sound waves enter these second through-holes 210, they can form at least one of diffracted sound waves and direct sound waves, which are then transmitted to the outside of the body 100 via the first through-hole 110.

[0083] By positioning the projections of at least one second through-hole 210 toward the first through-hole 110 within the area enclosed by the first through-hole 110, the portion of the support member 200 corresponding to the first through-hole 110 includes not only a solid portion for supporting the waterproof and sound-permeable membrane 300, but also a channel for sound waves to pass through. Similarly, after the original sound waves enter these second through-holes 210, they can form at least one of diffracted sound waves and direct sound waves, which are then transmitted to the outside of the body 100 via the first through-hole 110.

[0084] Specifically, each of the second through holes 210 can be distributed around the periphery of the first through hole 110, such that the sum of the areas of the portions of each of the second through holes 210 that are closed by the waterproof and sound-permeable membrane 300 is greater than the area of ​​the portion of the first through hole 110 that is connected to the second through hole 210, thereby making the sound-permeable area of ​​the waterproof and sound-permeable membrane 300 larger. Compared with related technologies that directly cover the opening with the waterproof and sound-permeable membrane assembly, the waterproof and sound-permeable membrane 300 provided in this application embodiment has a larger sound-permeable area, allowing more sound waves to pass through the waterproof and sound-permeable membrane 300, and thus allowing more sound waves to be transmitted to the outside of the body 100. This allows more sound energy to be released from the receiving cavity 120 to the outside of the body 100, further reducing the accumulation of sound energy in the receiving cavity 120, and further reducing the vibration of the body 100.

[0085] In summary, both the portion of the support member 200 corresponding to and not corresponding to the first through-hole 110 include a solid portion for supporting the waterproof acoustic membrane 300 and a channel for sound waves to pass through. This allows the support member 200 to not only increase the amount of sound waves passing through the waterproof acoustic membrane 300, but also to provide better support for the waterproof acoustic membrane 300 due to the wider distribution of its solid portion. In practical applications, the waterproof acoustic membrane 300 is typically thin and flexible; insufficient support may lead to deformation or damage under external forces. The distribution design of multiple third through-holes 220 allows the solid portion of the support member 200 to support the waterproof acoustic membrane 300 over a larger area, effectively preventing excessive deformation of the waterproof acoustic membrane 300 under pressure differentials or external forces.

[0086] Furthermore, at least two third through holes 220 can enhance the overall structural stability of the support 200. Compared to a single large hole design, the multi-hole design retains more solid parts, improves the overall structural strength and rigidity of the support 200, and reduces the possibility of deformation or damage to the support 200 during long-term use.

[0087] For further information, please refer to [link / reference]. Figure 4 The diameter of the second through hole 210 gradually decreases along the direction from the waterproof and sound-permeable membrane 300 to the first through hole 110.

[0088] The area of ​​the waterproof sound-permeable membrane 300 covering the second through hole 210 is the effective sound-permeable area of ​​the waterproof sound-permeable membrane 300. By setting the aperture of the second through hole 210 to gradually decrease along the direction from the waterproof sound-permeable membrane 300 to the first through hole 110, the effective sound-permeable area of ​​the waterproof sound-permeable membrane 300 is larger, so that more original sound waves can pass through the waterproof sound-permeable membrane 300 and enter the support member 200.

[0089] In some embodiments, the support member 200 is bonded, screwed, or welded to the body 100.

[0090] In some examples, an adhesive can be applied between the contact surfaces of the support 200 and the body 100, and the support 200 can be firmly fixed to the body 100 by the adhesive action of the adhesive. The bonding method is simple to operate, the connection is reliable, and the bonded interface is flat without gaps or protrusions, which helps to maintain the integrity of the sound wave transmission channel and reduce the loss of sound waves during transmission.

[0091] In other examples, threaded structures can be provided at corresponding positions on the support member 200 and the body 100, allowing for a tight connection between the support member 200 and the body 100 by rotating the threaded structures. The advantage of the threaded connection is its high connection strength and good disassembly capability, facilitating later maintenance and replacement. When the waterproof and sound-permeable membrane 300 needs inspection or replacement, the support member 200 can be easily disassembled without damaging the structure of the body 100, improving the product's maintainability.

[0092] In other examples, the support 200 can be firmly connected to the body 100 through methods such as hot melting or ultrasonic welding. The connection interface formed by welding has extremely high sealing performance and strength, which can effectively prevent moisture or impurities from seeping in from the connection, thereby further improving the waterproof performance of the shell 10. At the same time, the connection structure formed by welding is stable and reliable, and is not easy to loosen due to external forces or long-term use, which can extend the service life of the shell 10.

[0093] In some embodiments, the waterproof and sound-permeable membrane 300 is bonded or pressed together with the support member 200.

[0094] By bonding the waterproof and sound-permeable membrane 300 to the support member 200, not only is the connection between the waterproof and sound-permeable membrane 300 and the support member 200 simple to operate and firmly connected, but it also ensures that a sealed connection is formed between the waterproof and sound-permeable membrane 300 and the support member 200 to prevent water and other impurities from seeping into the interior of the shell 10 from the connection between the support member 200 and the waterproof and sound-permeable membrane 300.

[0095] The waterproof and acoustically permeable membrane 300 can also be connected to the support member 200 by compression. Specifically, slots or protrusions can be provided on the support member 200, and the waterproof and acoustically permeable membrane 300 is then compressed onto these structures. The friction and pressure between the structures fix the waterproof and acoustically permeable membrane 300 to the support member 200. By compression connecting the waterproof and acoustically permeable membrane 300 to the support member 200, no additional adhesive is needed, avoiding the aging problems that adhesives may cause. Furthermore, the compression connection facilitates future maintenance and replacement of the waterproof and acoustically permeable membrane 300; simply releasing the pressure removes the old membrane, and then re-compression with a new one completes the replacement.

[0096] For some specific implementation methods, please refer to Figure 5The housing 10 also includes an adhesive layer 400, through which the waterproof and sound-permeable membrane 300 is bonded to the support member 200.

[0097] In this embodiment, the adhesive layer 400 can be first coated onto the support member 200, and then the waterproof and sound-permeable membrane 300 can be pressed onto the support member 200 coated with the adhesive layer 400; or the adhesive layer 400 can be first coated onto the waterproof and sound-permeable membrane 300, and then the waterproof and sound-permeable membrane 300 coated with the adhesive layer 400 can be pressed onto the support member 200; or the adhesive layer 400 can be coated on both the waterproof and sound-permeable membrane 300 and the support member 200, and then the two can be pressed together.

[0098] Furthermore, the adhesive layer 400 is a hot melt adhesive layer, a pressure-sensitive adhesive layer, or a photosensitive adhesive layer.

[0099] When the adhesive layer 400 is a hot melt adhesive layer, the hot melt adhesive can be melted by heating and then cooled and solidified, thereby firmly bonding the waterproof and sound-permeable membrane 300 to the support member 200. The hot melt adhesive layer is not easily affected by environmental humidity. By setting the adhesive layer 400 as a hot melt adhesive layer, the waterproof performance between the support member 200 and the waterproof and sound-permeable membrane 300 is better.

[0100] When the adhesive layer 400 is a pressure-sensitive adhesive layer, only a certain pressure needs to be applied to achieve bonding between the support member 200 and the waterproof and sound-permeable membrane 300. The pressure-sensitive adhesive layer has a certain degree of elasticity, which can buffer external impacts to a certain extent, thereby enhancing the stability of the connection between the waterproof and sound-permeable membrane 300 and the support member 200.

[0101] When the adhesive layer 400 is a photosensitive adhesive layer, it can be cured by methods such as ultraviolet light irradiation, thereby firmly bonding the waterproof and sound-permeable membrane 300 to the support 200. The photosensitive adhesive cures quickly, has high bonding strength after curing, and allows for precise control of the adhesive layer thickness and distribution, making it suitable for applications requiring high bonding precision.

[0102] In other embodiments, the waterproof and sound-permeable membrane 300 is a polyurethane film, a polyethylene film, a polypropylene film, a polyester film, or a polyimide film.

[0103] Polyurethane film, polyethylene film, polypropylene film, polyester film, or polyimide film are all polymeric material films with multiple micropores. These micropores allow sound waves to pass through while effectively blocking water molecules or other impurities.

[0104] Furthermore, these films possess excellent mechanical strength and elasticity, allowing them to maintain structural integrity during long-term use without easily breaking or deforming.

[0105] In some embodiments, please continue reading Figure 1The body 100 includes a middle frame 130 and a housing 140 connected to the middle frame 130, and a first through hole 110 is provided on the middle frame 130 or the housing 140.

[0106] The middle frame 130 and the outer shell 140 together form a receiving cavity 120, which is used to house the acoustic component 20 of the electronic device. When the first through hole 110 is provided on the middle frame 130, sound waves can be transmitted from the receiving cavity 120 to the outside of the middle frame 130 in sequence through the waterproof and sound-permeable membrane 300, the support member 200 and the first through hole 110; when the first through hole 110 is provided on the outer shell 140, sound waves can be transmitted from the receiving cavity 120 to the outside of the outer shell 140 in sequence through the waterproof and sound-permeable membrane 300, the support member 200 and the first through hole 110.

[0107] In this embodiment, the first through hole 110 can be flexibly opened on the middle frame 130 or the outer shell 140 according to the internal layout and appearance design requirements of the electronic device, so that the sound wave can be transmitted from a better position.

[0108] It should be understood that the embodiments of this application are not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
