[0033] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0034] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be understood as limiting the present application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0035] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0036] According to one embodiment of the present application, a microphone is provided. Figure 1 As shown, the microphone includes a substrate 1, a shell 2 and a waterproof module 3; the shell 2 is arranged on the substrate 1, and an inner chamber 101 is formed between the shell 2 and the substrate 1, and the inner chamber 101 has a first air vent 11 connected to the outside world; the waterproof module 3 is detachably arranged on the side of the first air vent 11 away from the inner chamber 101 to separate the inner chamber 101 from the external liquid.

[0037] Specifically, if Figure 1As shown, the microphone of the embodiment of the present application includes a substrate 1 and a housing 2. The housing 2 can be provided on the substrate 1 via a conductive adhesive cover to form the inner chamber 101. The inner chamber 101 can be fixed with a MEMS (Micro Electro Mechanical System) chip and an ASIC (Application Specific Integrated Circuit) chip. The MEMS chip 6 and the ASIC chip 7 can be fixed to the substrate 1 via solder connection, conductive adhesive connection, gold-tin solder connection, etc., so that the microphone can directly use the substrate 1 to arrange and support the MEMS chip 6 and the ASIC chip 7 without the need for an additional support structure. The inner chamber 101 also has a first vent 11 that communicates with the outside world. The first vent 11 is provided on the substrate 1 and extends through the substrate 1. Alternatively, the first vent 11 can be provided on the housing 2 and extends through the housing 2. Those skilled in the art can make their own choices based on actual needs, and this application does not impose any specific restrictions here.

[0038] The microphone further includes a waterproof module 3, which is detachably mounted on a side of the first vent 11 away from the inner chamber 101 to separate the inner chamber 101 from external liquids, thereby effectively improving the microphone's waterproof capabilities. The waterproof module 3 can be mounted on a side of the first vent 11 away from the inner chamber 101 by threaded connection, snap connection, or latch connection, so that when the microphone is used in different electronic devices, a waterproof module 3 of a corresponding grade can be installed based on the actual waterproof requirements of the electronic device. This effectively achieves waterproof functionality for microphones of different performances, expands the microphone's applicable range, and increases the flexibility of the electronic device.

[0039] The microphone further includes a first gold wire 8 and a second gold wire 9. The MEMS chip 6 is electrically connected to the ASIC chip 7 via the first gold wire 8, and the ASIC chip 7 is electrically connected to the substrate 1 via the second gold wire 9, thereby effectively improving the integration of the microphone.

[0040] In one embodiment, the waterproof module 3 includes a supporting portion 31 and a waterproof membrane 32, the supporting portion 31 includes a first protrusion 311 and a second protrusion 312, the first protrusion 311 is connected to the shell 2, the second protrusion 312 abuts against the side of the substrate 1 away from the shell 2, the second protrusion 312 supports the waterproof membrane 32, and the waterproof membrane 32 separates the inner chamber 101 from the external liquid.

[0041] Specifically, if Figure 1 As shown, the waterproof module 3 described in the embodiment of the present application includes a support portion 31 and a waterproof membrane 32. The material of the support portion 31 includes at least one of stainless steel, Teflon, plastic, aluminum alloy, and silicone rubber. This allows the present application to select an appropriate material based on the actual needs of the microphone to reduce the volume of the waterproof module 3, thereby better meeting the miniaturization and micro-miniaturization requirements of electronic devices. The support portion 31 can be formed by injection molding to further enhance the reliability and stability of the support portion 31. The waterproof membrane 32 includes at least one of an ePTFE film, a PI film, a silicone film, and a metal film to effectively improve the waterproof capability of the microphone and facilitate the installation of a waterproof module 3 of a corresponding grade based on the actual waterproof requirements of the electronic device.

[0042] The supporting portion 31 includes a first protrusion 311 and a second protrusion 312. The first protrusion 311 and the second protrusion 312 can form an integrated structure so that the first protrusion 311 is arranged at both ends of the width direction of the second protrusion 312. Therefore, after the waterproof module 3 is connected to the shell 2 through the first protrusion 311, the reliability and stability of the waterproof module 3 can be effectively improved.

[0043] The width dimension of the second protrusion 312 can be greater than the width dimension of the substrate 1, so that after the first protrusion 311 is set at both ends of the second protrusion 312 in the width direction, the first protrusion 311 can extend along the height direction of the second protrusion 312 to the shell 2 and be connected to the shell 2, and after the first protrusion 311 is connected to the shell 2, the side of the second protrusion 312 close to the substrate 1 can abut against the substrate 1, thereby realizing the support of the second protrusion 312 to the substrate 1.

[0044] In addition, if Figure 1 As shown, the second protrusion 312 also includes an installation area for installing and supporting the waterproof membrane 32, so that after the waterproof membrane 32 is installed, the waterproof membrane 32 can separate the inner chamber 101 from the external liquid, preventing the external liquid from entering the inner chamber 101 and damaging the MEMS chip 6 and ASIC chip 7 in the inner chamber 101.

[0045] In addition, in the embodiment of the present application, the connection between the first protrusion 311 and the shell 2 can be a threaded connection, a snap connection or a pin connection. Those skilled in the art can choose according to actual needs, and the present application does not make any specific restrictions here.

[0046] It should be noted that the width direction in the embodiment of the present application refers to the direction of the first protrusion 311 toward the shell 2, and the height direction refers to the direction of the substrate 1 toward the shell 2.

[0047] In one embodiment, the support portion 31 also includes a third protrusion 313, and the third protrusion 313 is provided with a second ventilation hole 3131; a accommodating cavity 102 is formed between the substrate 1, the second protrusion 312 and the third protrusion 313, and the waterproof membrane 32 can separate the accommodating cavity 102 into a first chamber 1021 connected to the first ventilation hole 11 and a second chamber 1022 connected to the second ventilation hole 3131.

[0048] Specifically, if Figure 1 As shown, the third protrusion 313 of the embodiment of the present application can form an integral structure with the second protrusion 312, so that the third protrusion 313 is disposed at both ends in the width direction of the second protrusion 312. The third protrusion 313 is formed with a second vent 3131, which corresponds to the first vent 11, so that external air can enter the inner chamber 101 through the second vent 3131 and the first vent 11 in sequence.

[0049] After the waterproof module 3 is connected to the shell 2 through the first protrusion 311, the accommodating cavity 102 can be formed between the substrate 1, the second protrusion 312 and the third protrusion 313. The waterproof membrane 32 is arranged in the accommodating cavity 102 and divides the accommodating cavity 102 into a first chamber 1021 connected to the first vent 11 and a second chamber 1022 connected to the second vent 3131.

[0050] At this time, external air can enter the inner chamber 101 through the second chamber 1022 and the first chamber 1021, thereby effectively improving the performance of the microphone. External liquid is blocked by the waterproof membrane 32 in the second chamber 1022, thereby effectively ensuring the waterproof performance of the waterproof module 3.

[0051] In one embodiment, the waterproof module 3 further includes a dustproof net 33 , and the dustproof net 33 is fixed to the second chamber 1022 via the third protrusion 313 .

[0052] Specifically, if Figure 1 As shown, the waterproof module 3 described in the embodiment of the present application can also realize the anti-foreign matter function of the microphone by setting a dustproof net 33, so as to effectively prevent external solid impurities from damaging the waterproof membrane 32 and affecting the waterproof performance of the waterproof module 3.

[0053] The dust screen 33 can be secured to the second chamber 1022 via the third protrusion 313, thereby improving the reliability and stability of the dust screen 33. The dust screen 33 can include at least one of a stainless steel woven mesh, a PET mesh, and a PA mesh, allowing the microphone to select a suitable material for the dust screen based on the actual needs of the electronic device, thereby effectively enhancing the dust screen 33's ability to block external solid impurities and further ensuring the waterproof function of the waterproof membrane 32.

[0054] In one embodiment, a width of the second protrusion 312 is greater than a width of the third protrusion 313 .

[0055] Specifically, if Figure 1 As shown, in this embodiment of the present application, the width dimension of the second protrusion 312 is H1, and the width dimension of the third protrusion 313 is H2. Thus, by setting the width dimension of the second protrusion 312 to be larger than the width dimension of the third protrusion 313, the larger second protrusion 312 can effectively support the substrate 1 after the waterproof module 3 is connected to the housing 2, effectively preventing the waterproof module 3 from falling off due to vibration, and further enhancing the reliability and stability of the connection between the waterproof module 3 and the housing 2. The relatively smaller third protrusion 313 can also form a larger second cavity 1022, so that after the dust net 33 is installed in the second cavity 1022, it can better block external solid impurities, thereby further improving the waterproof performance of the waterproof module 3.

[0056] Among them, when the width dimension of the second protrusion 312 is greater than the width dimension of the third protrusion 313, the cross-sectional dimension of the dustproof net 33 in the embodiment of the present application is greater than the cross-sectional dimension of the waterproof membrane 32, so that the larger dustproof net 33 can better prevent external solid impurities from entering the accommodating cavity and affecting the waterproof membrane 32.

[0057] In one embodiment, the dustproof net 33 is provided with a fluorine-containing coating.

[0058] Specifically, since the microphone described in the embodiment of the present application is affected by liquid oil in addition to liquid water during use, in order to further avoid the influence of other liquid impurities on the performance of the microphone, the present application also provides a fluorine-containing coating on the dustproof net 33.

[0059] Therefore, the present application further enhances the dustproof net 33's blocking effect on external solid impurities through the high weather resistance, high water resistance, high pollution resistance and high chemical resistance of the fluorine-containing coating.

[0060] In one embodiment, the second protrusion 312 includes a notch 3121 , and the waterproof module 3 is connected to the electronic device through the notch 3121 .

[0061] Specifically, if Figure 1 As shown, in this embodiment of the present application, a notch 3121 is provided on the side of the second protrusion 312 away from the waterproof membrane 32. This notch 3121 can form a snap fit with a protrusion on the housing of the electronic device. Thus, the present application is better secured to the housing 2 of the electronic device through the notch 3121, effectively enhancing the reliability and stability of the microphone and electronic device combination.

[0062] In addition, when the width of the second protrusion 312 is greater than the width of the third protrusion 313, the present application can also set a larger gap 3121 through the larger second protrusion 312, thereby further improving the reliability and stability of the combination of the microphone and electronic device.

[0063] Of course, the notch 3121 described in this application can also be set at other positions of the second protrusion 312, as long as it can be fixed to the electronic device. Those skilled in the art can make a choice according to actual needs, and this application does not make any specific restrictions here.

[0064] In one embodiment, the microphone further includes a sealing member 4 , which is located between the housing 2 and the first protrusion 311 . The sealing member 4 is interference-fitted with the housing 2 and the first protrusion 311 .

[0065] Specifically, if Figure 1 As shown, the microphone of the embodiment of the present application further includes a sealing member 4, which can be made of at least one of rubber, silicone rubber, low-density polyethylene film, silicone, foam, and waterproof glue. Thus, by providing the sealing member 4 between the housing 2 and the first protrusion 311, the present application provides an interference fit between the sealing member 4, the housing 2, and the first protrusion 311, thereby achieving connection between the housing 2 and the first protrusion 311. Furthermore, the sealing member 4 is prevented from entering the inner chamber 101 through the connection between the housing 2 and the first protrusion 311, thereby preventing the performance of the microphone from being affected.

[0066] In one embodiment, the microphone further includes a soft board 5 , which is disposed on a side of the substrate 1 facing away from the housing 2 , and is electrically connected to the substrate 1 .

[0067] Specifically, if Figure 1As shown, the microphone in this embodiment of the present application further includes a flexible board 5, which can be fixed to the side of the substrate 1 facing away from the housing 2 by welding. Thus, after the waterproof module 3 is connected to the housing 2 via the first protrusion 311, the flexible board 5 can be located between the substrate 1 and the second protrusion 312, enabling the second protrusion 312 to support the flexible board 5. Thus, by disposing the flexible board 5 on the side of the substrate 1 facing away from the housing 2, the microphone can be directly connected to an electronic device via the flexible board 5, facilitating direct use of the microphone with the electronic device and effectively improving the efficiency of the microphone.

[0068] According to another embodiment of the present application, an electronic device is provided, which includes the microphone described in the embodiment of the present application.

[0069] Specifically, the electronic device described in the embodiments of the present application can be any one of a mobile phone, a tablet computer, a personal digital assistant, a television, a smart wearable product, a virtual reality terminal device, an augmented reality terminal device, a rechargeable small household appliance (such as a soymilk maker, a robot vacuum), a drone, a radar, aerospace equipment, and an in-vehicle device. The microphone can be directly fixed to the above-mentioned electronic device, or the microphone can be detachably installed in the above-mentioned electronic device.

[0070] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.
