[0023] The following description provides specific application scenarios and requirements for this specification, with the goal of enabling those skilled in the art to make and use the contents of this specification. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the embodiments shown, but is intended to be accorded the broadest scope consistent with the claims.

[0024] The terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. For example, as used herein, the singular forms "a," "an," and "the" may also include the plural forms unless the context clearly indicates otherwise. When used in this specification, the terms "comprise," "include," and / or "contain" are intended to refer to the presence of the associated integers, steps, operations, elements, and / or components, but do not preclude the presence of one or more other features, integers, steps, operations, elements, components, and / or groups or the addition of other features, integers, steps, operations, elements, components, and / or groups in the system / method.

[0025] In this application, "X includes at least one of A, B, or C" means that X includes at least A, or X includes at least B, or X includes at least C. In other words, X can include only any combination of A, B, and C, or it can include any combination of A, B, and C as well as other possible contents / elements. The arbitrary combination of A, B, and C can be A, B, C, AB, AC, BC, or ABC.

[0026] In this application, unless explicitly stated otherwise, the association relationship between structures can be a direct association relationship or an indirect association relationship. For example, when describing "A is connected to B", unless it is explicitly stated that A is directly connected to B, it should be understood that A can be directly connected to B or indirectly connected to B; for another example, when describing "A is above B", unless it is explicitly stated that A is directly above B (AB are adjacent and A is above B), it should be understood that A can be directly above B or indirectly above B (AB is separated by other elements and A is above B). And so on.

[0027] These and other features of this specification, as well as the operation and function of the associated elements of the structure, and the economical assembly and manufacture of the components, can be significantly improved with consideration of the following description. The description also includes all figures and text referenced in the drawings herein, all of which form a part of this specification. However, it should be expressly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.

[0028] When users use electronic devices outdoors in the rain or while swimming, water may enter electronic components such as circuit boards through the gaps in the cables and damage the electronic devices. In the prior art, water is prevented from seeping into the gaps in the cables by sealing the cables and the electronic devices. The sealed connection between the cables and the electronic devices is achieved by bonding the protective layer on the cable surface to the housing of the electronic device with a sealant. The cable surface is usually covered with a protective layer, such as rubber, plastic, paint, silicone, and various fiber product protective layers, which have the characteristic of being non-sticky. Therefore, the bonding effect between the protective layer on the cable surface and the housing of the electronic device is poor, resulting in poor waterproof performance of the electronic device.

[0029] In view of this point, the present application provides a waterproof electronic device, which replaces the bonding between the cable protective layer and the electronic device housing with the bonding between the cable connector and the electronic device housing, thereby improving the bonding effect and further improving the waterproof performance of the waterproof electronic device.

[0030] The waterproof electronic device may be an electronic device with a waterproof function. The electronic device may be a device composed of electronic components such as integrated circuits, transistors, and electron tubes, and uses electronic technology (including software) to function. The waterproof electronic device may include wearable devices such as smart watches, smart glasses, and headphones. For the convenience of presentation, the following content is described using headphones as an example of a waterproof electronic device. It should be noted that those skilled in the art should understand that waterproof electronic devices such as other electronic devices are also within the scope of protection of this specification.

[0031] The waterproof headphones can be any type of headphones. For example, they can be wired headphones. The receiver in the wired headphones can receive electrical signals from a media player via wired transmission, thereby converting the electrical signals into sound waves audible to the human ear. For example, the waterproof headphones can be wireless headphones. The receiver in the wireless headphones can receive electrical signals from a media player via wireless transmission, thereby converting the electrical signals into sound waves audible to the human ear. The waterproof headphones can be air conduction headphones. Air conduction headphones can convert electrical signals into air vibration signals. The air vibration signals can be transmitted to the ear canal. The eardrum in the ear can convert the air vibration signals into sound. For another example, the waterproof headphones can be bone conduction headphones. Bone conduction headphones can convert electrical signals into mechanical vibration signals. The mechanical vibration signals can cause the skull to vibrate, causing the perilymph to produce fluctuations of the same frequency, and stimulating the cochlear cochlear organ to produce hearing. For another example, the waterproof headphones can be a combination of air conduction and bone conduction headphones. In some embodiments, the waterproof headphones can also include a data storage unit. In this case, the waterproof earphones can be independent of an external media player and can also play the audio data stored in the built-in data storage unit when no signal transmission is performed with the external media player. This specification does not limit the type of waterproof earphones.

[0032] As previously mentioned, the waterproof electronic device is a waterproof headset. Figure 1A shows a front view of a waterproof headset 001 provided according to some exemplary embodiments of this application; Figure 1B shows a side view of a waterproof headset 001 provided according to some exemplary embodiments of this application. Waterproof headset 001 includes a main body 300 and a cable assembly 500. In some embodiments, waterproof headset 001 also includes a core assembly 100.

[0033] In some embodiments, the core assembly 100 can also be referred to as a speaker assembly. The core assembly 100 can convert electrical signals into audible sound waves. There can be one or two core assemblies 100. When there is only one core assembly 100, the waterproof earphones 001 can be used in applications where stereo sound is not particularly important, such as hearing aids for hearing-impaired patients and live teleprompting for hosts. When a user wears the waterproof earphones 001, the core assembly 100 can be worn on either the user's left or right ear. When there are two core assemblies 100 and the user wears the waterproof earphones 001, the two core assemblies 100 are worn on different ears of the user. In this case, both core assemblies 100 can produce sound, giving the waterproof earphones 001 a stereo sound effect and improving user perception of the waterproof earphones 001. In some embodiments, the two core assemblies 100 can be provided independently. That is, the two core assemblies 100 can exist independently and can be worn separately. For example, the two movement assemblies 100 can be worn on different ears, or on the ears of different users, making the waterproof earphones 001 more flexible to use. In this case, the two movement assemblies 100 can operate independently. In some embodiments, the two movement assemblies 100 can also be connected together (for example, via a cable assembly 500). In this case, the two movement assemblies 100 can operate simultaneously and be controlled uniformly for better sound quality. In some embodiments, the movement assembly 100 can be an air conduction movement. In this case, when the user wears the waterproof earphones 001, the movement assembly 100 can be in-ear or open-ear. In some embodiments, the movement assembly 100 can also be a bone conduction movement. In this case, when the user wears the waterproof earphones 001, the movement assembly 100 can be mounted on the outside of the user's ear. For example, the movement assembly 100 can be mounted on the outside of the ear, close to the human skin, so that sound waves are transmitted to the inside of the ear through the vibration of the human skin and bones. In some embodiments, the movement assembly 100 can be a combination of an air conduction movement and a bone conduction movement.

[0034] The main body 300 can be electrically connected to the core assembly 100 to control the core assembly 100. In waterproof earphones 001, the main body 300 can be the ear hook component of the waterproof earphones 001. In some embodiments, the main body 300 can receive electrical signals from an external media player and transmit the electrical signals to the core assembly 100. In some embodiments, the main body 300 can have a built-in data storage unit. In this case, the main body 300 can transmit audio data from the built-in data storage unit to the core assembly 100. There can be one or more main bodies 300. In some embodiments, each core assembly 100 can be connected to a main body 300. In some embodiments, the waterproof electronic device is waterproof earphones 001, which can include two core assemblies 100, wherein the two core assemblies 100 can share a single main body 300. When the waterproof earphones 001 include two core assemblies 100 and two main bodies 300, the two core assemblies 100 are electrically connected to the two main bodies 300, respectively. In this case, the two main bodies 300 can be independently provided to independently control the core assembly 100. The two main bodies 300 can also be connected together, for example, by connecting the two main bodies 300 together through a cable assembly 500 to achieve unified control of the two core assemblies 100.

[0035] In some embodiments, the waterproof earphones 001 may further include a cable assembly 500. The cable assembly 500 may connect the two core assemblies 100. In the waterproof earphones 001, the cable assembly 500 may be a rear hanging wire assembly of the waterproof earphones 001. For example, when the two core assemblies 100 are electrically connected to the two main bodies 300 respectively, the cable assembly 500 may electrically connect the two main bodies 300. For another example, when the two core assemblies 100 share a main body 300, the main body 300 may be close to any one of the two core assemblies 100, and the cable assembly 500 may electrically connect the main body 300 to the other of the two core assemblies 100.

[0036] The cable assembly 500 can be any component that can conduct electricity between various electronic components. The cable assembly 500 is mainly used to achieve electrical connection between the various electronic components of the waterproof earphones 001. For example, when two core assemblies 100 are electrically connected to two main bodies 300 respectively, the cable assembly 500 can electrically connect the two main bodies 300. For another example, when two core assemblies 100 share a main body 300, the main body 300 can be close to either of the two core assemblies 100, and the cable assembly 500 can electrically connect the main body 300 to the other core assembly 100.

[0037] It should be noted that the connection between the core assembly 100 and the main body 300 can also be sealed with a sealant to improve the waterproof performance of the waterproof earphone 001. Similarly, the connection between the main body 300 and the cable assembly 500 can also be sealed with a sealant to improve the waterproof performance of the waterproof earphone 001.

[0038] FIG2 shows an exploded view of a waterproof headset 001 according to some exemplary embodiments of the present application. As shown in FIG2 , a main body 300 includes a housing 320 , an electronic component 340 , and a first protective cover 350 .

[0039] The silo 320 can be a mounting base for the electronic component 340. The silo 320 can be a thin-walled shell-like structure with a hollow interior. The electronic component 340 can be installed inside the silo 320. The shape of the silo 320 can be any shape to accommodate the installation of other components. The shape of the silo 320 can be ergonomic to facilitate user use. The material of the silo 320 can be any material, such as metal, plastic, polymer, etc. This specification does not limit the shape and material of the silo 320.

[0040] In some embodiments, the housing 320 can be integrally formed. In some embodiments, the housing 320 can include at least two housings. For example, the housing 320 can include two housings: a main housing 321 and a housing cover 323. The main housing 321 and the housing cover 323 are assembled together to form a hollow housing structure. In some embodiments, the housing 320 can also be composed of more than two housings assembled together, which is not discussed in detail in this specification. The main housing 321 and the housing cover 323 are thin-walled components. They can be assembled together to form a storage compartment. The storage compartment can accommodate other components and allow them to be installed within the compartment, thereby protecting them from dust. For example, the electronic component 340 can be installed within the housing 320, for example, within the storage compartment. The connection between the main housing 321 and the housing cover 323 can be sealed with sealant to enhance the waterproof performance of the housing 320.

[0041] The electronic component 340 may include a circuit board. The core assembly 100 may be electrically connected to the circuit board. The core assembly 100 and the circuit board may be electrically connected via a cable assembly 500. The circuit board may control the core assembly 100. The circuit board is a chip integrated circuit with integrated headphone functionality. In some embodiments, the circuit board includes a radio frequency unit for receiving and transmitting signals, such as communication elements such as Bluetooth, NFC, and Wi-Fi, to enable communication with an external media player. In some embodiments, the circuit board includes a CPU unit for processing data and a DSP unit for audio decoding. In some embodiments, the circuit board also includes a data storage unit for storing audio data. The circuit board may be used for short-range wireless communication, audio transmission, data transmission, data storage, location services, device networks, and the like. This specification does not limit the type of circuit board. Specifically, the circuit board may include a flexible printed circuit board (FPC), a rigid printed circuit board (PCB), and a rigid-flex PCB. That is, the circuit board may be any circuit or processor capable of performing one or more functions, or any combination thereof.

[0042] The main body 300 also includes a first protective cover 350. The first protective cover 350 at least partially covers the outer surface of the housing 320. In some embodiments, the first protective cover 350 may cover the entire outer surface of the housing 320. In some embodiments, the first protective cover 350 may cover a portion of the outer surface of the housing 320. When the first protective cover 350 covers a portion of the outer surface of the housing 320, the first protective cover 350 may cover the outer surface of the housing 320 at the end closest to the core assembly 100. In some embodiments, the first protective cover 350 may also cover the outer surface of the cable connecting the electronic component 340 to the core assembly 100. In some embodiments, the first protective cover 350 may also cover the outer surface of the core assembly 100. The first protective cover 350 and the outer surfaces of other components it covers may be sealed with sealant to enhance the waterproof performance of the waterproof earphones 001. For example, the first protective cover 350 may be sealed with the outer surface of the housing 320. Another example is the seal between the first protective cover 350 and the outer surface of the cable connecting the electronic component 340 to the core assembly 100.

[0043] The first protective cover 350 can be integrally formed or assembled from multiple protective covers. The first protective cover 350 can be injection molded around the outer periphery of the housing 320, or can be separately injection molded and then further fitted around the outer periphery of the housing 320. The first protective cover 350 and the second protective cover 350 can be made of a soft material with a certain degree of elasticity, such as soft silicone or rubber.

[0044] In some embodiments, the main body 300 may further include a control button 360. The control button 360 may be mounted on the housing 320 and partially exposed outside the housing 320 for user operation. The control button 360 may be electrically connected to the circuit board. By operating the control button 360, the user can control the circuit board to turn the waterproof earphones 001 on and off, adjust the volume, switch modes, and perform other functions, thereby enhancing the intelligence of the waterproof earphones 001 and improving the user experience.

[0045] In some embodiments, the main body 300 may further include a charging port 380. The charging port 380 may be mounted on the housing 320 and partially exposed outside the housing 320 for electrical connection to an external power source. The charging port 380 may be electrically connected to the circuit board to provide electrical energy to the circuit board. This electrical energy may be transferred through the circuit board to other components, such as the core assembly 100.

[0046] As previously described, the cable assembly 500 is electrically connected to the main body 300, enabling electrical connection between the circuit board of the main body 300 and the various electronic components of the waterproof earphones 001. The cable assembly 500 shown in Figure 2 can electrically connect two main bodies 300. As shown in Figure 2, the cable assembly 500 includes a connector 520, a cable 540, and a second protective cover 550. In some embodiments, the cable assembly 500 also includes an elastic wire 560. In some embodiments, the cable assembly 500 also includes a buckle 580.

[0047] The cable 540 can be any conductive wire, such as a wire. The cable 540 can be used to achieve electrical connection between the various electronic components of the electronic device. Furthermore, the cable 540 can be used to achieve electrical connection between the various electronic components of the waterproof earphones 001. One end of the cable 540 can be electrically connected to the electronic component 340 of one of the two main bodies 300. The other end of the cable 540 can be electrically connected to the electronic component 340 of the other main body 300, or it can be directly electrically connected to the movement assembly 100. The cable 540 can be one strand or multiple strands. When there are multiple circuits that need to be electrically connected in the waterproof earphones 001, the cable 540 can be set to multiple strands accordingly. For example, the cable 540 can be set to any number of strands, such as 1 strand, 2 strands, 3 strands, 5 strands, 6 strands, 8 strands, etc.

[0048] The surface of cable 540 is coated with a cable protective layer. The cable protective layer protects the cable insulation layer from mechanical damage and various environmental factors such as water, sunlight, biological damage, and fire during use, thereby maintaining the long-term stable electrical performance of the cable. Therefore, the cable protective layer is chemically and heat-resistant. The cable protective layer can be made of a variety of materials, such as rubber, plastic, paint, silicone, and various fiber product protective layers. Furthermore, the plastic can be polytetrafluoroethylene (PTFE).

[0049] The connector 520 can be connected to the housing 320. The connector 520 can cover the cable 540. The cable 540 can pass through the connector 520. Therefore, the connector 520 can serve as a medium for connecting the cable 540 and the housing 320. For example, when the cable 520 is electrically connected to the electronic component 340, the connector 520 can be connected to the housing 320 in the main body 300, and the cable 540 can pass through the connector 520, thereby passing through the housing 320 and entering the interior of the housing 320 to electrically connect with the electronic component 340. In some embodiments, the cable 540 and the connector 520 can be sealed by a sealant.

[0050] The connection between the connector 520 and the housing 320 can be sealed with a sealant. As previously mentioned, the surface of the cable 540 is covered with a cable protective layer. Due to the special material of the cable protective layer, the cable protective layer has low bonding reliability when bonding with other components. Therefore, the waterproof earphones 001 cover the cable 540 with the connector 520, and the sealed connection between the connector 520 and the housing 320 replaces the direct connection of the cable 540 and the housing 320 with sealant, making the sealed connection between the cable assembly 500 and the main body 300 more reliable, thereby improving the waterproof performance.

[0051] The molding process of the connector 520 can be any process. For example, injection molding, stamping or die casting. Another example is 3D printing, machining, etc. Among them, the connector 520 can be molded separately and then further assembled with the warehouse body 320. The material of the connector 520 can be metal to enhance the structural strength of the cable 540, and then enhance the connection strength between the cable 540 and the main body 300. The material of the connector 520 can be zinc, copper, aluminum, magnesium, lead, tin, lead-tin alloy and their alloys. Furthermore, the material of the connector 520 can be zinc alloy, so that the connector 520 is simple to mold and has good environmental performance. In addition, the connector 520 can also be made of plastic and processed by injection molding. Among them, the hardness of the connector 520 can be greater than the hardness of the warehouse body 320.

[0052] The cable assembly 500 also includes a second protective cover 550. The second protective cover 550 at least partially covers the outer surface of the cable 540. Specifically, the second protective cover 550 can cover the outer surface of the portion of the cable 540 located outside the warehouse body 320 and the connector 520. The second protective cover 550 can also at least partially cover the outer surface of the connector 520. For example, the second protective cover 550 can cover the outer surface of the portion of the connector 520 exposed outside the warehouse body 320. In some embodiments, the second protective cover 550 can also at least cover the outer surface of the warehouse body 320. For example, the second protective cover 550 can cover the outer surface of one end of the warehouse body 320 connected to the connector 520. That is, the second protective cover 550 can cover the outer surface of the end of the warehouse body 320 close to the cable assembly 500. The second protective cover 550 and the warehouse body 320 can be sealed by sealant, the warehouse body 320 and the cable 540 can be sealed by sealant, and the cable 540 and the connector 520 can be wrapped and sealed by the second protective cover 550 during the silicone molding process. The cable 540 and the connector 520 can also be filled with sealant for sealing. To improve the waterproof performance of the waterproof earphones 001. It should be noted that the second protective cover 550 abuts the first protective cover 350. That is, the ends of the second protective cover 550 and the first protective cover 350 that are close to each other are in contact to cover the entire warehouse body 320. The abutment between the second protective cover 550 and the first protective cover 350 is sealed by sealant. The waterproof earphones 001 extend the second protective cover 550 toward the main body 300 and at least partially cover the outer surface of the housing 320. This can extend the path for external water to enter the interior of the waterproof earphones 001 (such as the interior of the housing 320) from the connection between the cable assembly 500 and the main body 300, thereby increasing the resistance to water ingress and improving the waterproof effect of the waterproof earphones 001.

[0053] The second protective cover 550 can be integrally formed or composed of multiple protective covers. The second protective cover 550 can be injection molded around the cable 340, or it can be separately injection molded and then further wrapped around the cable 340. The second protective cover 550 can be made of a soft material with a certain degree of elasticity, such as soft silicone or rubber.

[0054] When water from outside penetrates the interior of the waterproof earphones 001 (e.g., the interior of the housing 320), the water inlet path, from the outside inward, includes the abutment between the first protective cover 350 and the second protective cover 550, the connection between the second protective cover 550 and the outer surface of the housing 320, the connection between the housing 320 and the connector 520, and the connection between the cable 540 and the housing 320. To enhance the waterproofing of the waterproof earphones 001, the water inlet path is filled with sealant. Specifically, the abutment between the first protective cover 350 and the second protective cover 550, the connection between the second protective cover 550 and the housing 320, the connection between the housing 320 and the connector 520, and the connection between the cable 540 and the housing 320 are filled with sealant. If the connector 520 does not cover the cable 540, the water inlet path, from the outside inward, includes the abutment between the first protective cover 350 and the second protective cover 550, the connection between the second protective cover 550 and the outer surface of the housing 320, and the connection between the housing 320 and the cable 540. Cable 540 is coated with a Teflon protective layer, but Teflon has poor adhesion. Furthermore, when multiple circuits in waterproof earphones 001 require electrical connection, cable 540 is configured with multiple strands. Small gaps exist between the strands, making it difficult for sealant to seal these gaps. Therefore, the bond between housing 320 and cable 540 is not strong, increasing the risk of water leakage. However, by using connector 520 to cover cable 540 and replacing the seal between housing 320 and cable 540 with a seal between housing 320 and connector 520, the seal is more secure and waterproof performance is improved.

[0055] In summary, the waterproof earphones 001 provide a connector 520 to wrap the cable 540, and seal the connector 520 with the housing 320, instead of directly connecting the cable 540 to the housing 320. This allows the connector 520 to be reliably sealed with the housing 320, thereby improving the waterproof effect of the waterproof earphones 001. In addition, the connection between the connector 520 and the housing 320 is located before the connection between the cable 540 and the housing 320. When external water penetrates into the waterproof earphones 001, it must first pass through the sealed connection between the connector 520 and the housing 320 before reaching the connection between the cable 540 and the housing 320. This increases the waterproof protection of the connection between the cable 540 and the housing 320, thereby improving the waterproof effect of the connection between the cable 540 and the housing 320. At the same time, the waterproof earphones 001 extend the water inlet path by extending the second protective cover 550 toward the housing 320 and at least partially covering the outer surface of the housing 320, thereby increasing the water inlet resistance and improving the waterproof effect.

[0056] As shown in Figure 2, the cable assembly 500 may also include an elastic wire 560. The elastic wire 560 may be curved to provide a certain clamping force when the user wears the headphones, allowing it to elastically deform according to the user's ear and head shape to accommodate users with different ear and head shapes. The cable 540 may be arranged along the extension direction of the elastic wire 560. For example, the cable 540 may be arranged parallel to the elastic wire 560. In another example, the cable 540 may be wrapped around the elastic wire 560. The elastic wire 560 may provide a certain amount of support for the cable 540. For example, when the two core assemblies 100 are electrically connected to the two main bodies 300, the ends of the elastic wire 560 may be connected to the two main bodies 300 respectively. In this case, when the user wears the waterproof headphones 001, the two main bodies 300 can be respectively hung outside the user's ears, and the cable assembly 500 is designed to be wrapped around the back of the user's head, with the two core assemblies 100 positioned near the two ears. At this time, the elastic metal wire 560 can provide a certain clamping force, so that the two movement components 100 are close to the user's skin to improve wearing reliability.

[0057] In some embodiments, the elastic wire 560 can be made of a memory material with excellent deformation recovery capabilities. Even if the cable assembly 500 is deformed by external forces, it can still return to its original shape when the force is removed, allowing continued use by the user, thereby extending the service life of the waterproof earphones 001. The memory material can include a memory alloy, a polymer memory material, an inorganic non-memory material, or the like. Furthermore, the memory alloy can include a titanium-nickel-copper memory alloy, a titanium-nickel-iron memory alloy, a titanium-nickel-chromium memory alloy, a copper-nickel memory alloy, a copper-aluminum memory alloy, a copper-zinc memory alloy, or an iron memory alloy. The polymer memory material can include polynorbornene, trans-polyisoprene, styrene-butadiene copolymer, cross-linked polyethylene, polyurethane, polylactone, a fluorinated polymer, polyamide, a cross-linked polyolefin, or polyester. The inorganic non-memory material can include memory ceramics, memory glass, garnet, or mica. In other embodiments, the elastic wire 560 can also be made of a non-memory material. Furthermore, the non-memory material may be aluminum alloy, chromium-molybdenum steel, scandium alloy, magnesium alloy, titanium alloy, magnesium-lithium alloy, nickel alloy or a combination thereof.

[0058] In some embodiments, the cable assembly 500 may further include a buckle 580. The buckle 580 may be used to connect and secure the connector 520 to the housing 320. Specifically, the connector 520 and the housing 320 may be provided with a slot. The buckle 580 is inserted into the slots of both the connector 520 and the housing 320, thereby securely connecting the connector 520 to the housing 320.

[0059] It should be noted that the connector 520 and the chamber body 320 may be fixedly connected by other means, such as bonding, threaded connection, welding, etc. This specification does not limit this.

[0060] FIG3 illustrates a schematic structural diagram of a connector 520 of a cable assembly 500 according to some exemplary embodiments of the present application. Specifically, as shown in FIG3 , connector 520 includes a mounting portion 521 and a connection hole 525 . In some embodiments, connector 520 further includes a raised portion 523 . In some embodiments, connector 520 further includes a plug hole 527 .

[0061] The mounting portion 521 is provided at one end of the connector 520 near the chamber body 320. The mounting portion 521 is used to connect to the chamber body 320. The mounting portion 521 is sealed to the chamber body 320. The shape and size of the mounting portion 521 match the shape and size of the portion of the chamber body 320 that connects to the mounting portion 521.

[0062] In some embodiments, the mounting portion 521 includes a second slot 521 - 1 that matches a buckle 580 . The buckle 580 can be inserted into the second slot 521 - 1 and the housing 320 to securely connect the mounting portion 521 to the housing 320 .

[0063] The connector 520 also has a connecting hole 525 extending therethrough. The cable 540 can pass through the connecting hole 525 and through the housing 320 to electrically connect to the electronic component 340. In some embodiments, the diameter of the connecting hole 525 is larger than the diameter of the cable 540, thereby allowing the cable 540 to pass through the connecting hole 525. In some embodiments, the diameter of the connecting hole 525 can be equal to or smaller than the diameter of the cable 540 to form an interference fit with the cable 540, further enhancing the sealing effect.

[0064] A raised portion 523 is provided at the other end of the connector 520. The raised portion 523 serves as a stopper when the connector 520 is connected to the housing 320. The raised portion 523 is located at the end of the mounting portion 521 that is away from the housing 320. The raised portion 523 protrudes outward relative to the mounting portion 521. When the mounting portion 521 of the connector 520 is connected to the housing 320, the housing 320 abuts against the raised portion 523. A sealant is used to seal the housing 320 and the raised portion 523, thereby enhancing the waterproof performance of the waterproof earphones 001.

[0065] In some embodiments, connector 520 further includes a socket 527. Socket 527 can be a connection interface for elastic wire 560. Elastic wire 560 is connected to connector 520 through socket 527. Elastic wire 560 can be inserted into and secured to socket 527. Elastic wire 560 can be secured to socket 527 using a variety of methods, including interference fit, bonding, welding, riveting, heat fusion, or a combination thereof.

[0066] It should be noted that the second protective cover 550 may cover the portion of the connector 520 other than the mounting portion 521 .

[0067] FIG4 shows a cross-sectional view AA of the main body of the waterproof earphone 001 according to FIG1A of the present application. As shown in FIG4 , the housing 320 includes a mounting hole 325. In some embodiments, the housing 320 further includes a water retaining portion 327.

[0068] The warehouse body 320 may be provided with a mounting hole 325. The mounting hole 325 may be provided on the main warehouse body 321. The mounting hole 325 may be provided at one end of the main warehouse body 321 close to the cable assembly 500. The mounting hole 325 is used for installation with the connector 520. The mounting hole 325 of the warehouse body 320 and the shape and size of the mounting portion 521 are adapted. The cross-sectional shape of the mounting hole 325 may be any shape, such as a circle, a quadrilateral, a polygon, an ellipse, and the like. When the connector 520 is connected to the warehouse body 320, the mounting portion 521 is passed through the mounting hole 325, and the warehouse body 320 may rest against the protrusion 523. The cable 540 may pass through the through hole 525 of the connector 520, thereby extending through the mounting hole 325 into the interior of the warehouse body 320 and electrically connecting with the electronic component 340.

[0069] As previously mentioned, in order to improve the waterproof performance of the waterproof earphones 001, the connection between the housing 320 and the connector 520 is sealed by a sealant. Specifically, the mounting portion 521 and the mounting hole 325 are sealed by a sealant. Furthermore, the outer surface of the mounting portion 521 and the inner surface of the mounting hole 325 are sealed by a sealant. In order to further improve the waterproof effect between the mounting portion 521 and the mounting hole 325, at least one third glue groove is distributed on at least one of the inner surface of the mounting hole 325 and the outer surface of the mounting portion 521. Each of the at least one third glue grooves can surround the mounting portion 521. The third glue grooves can be grooves continuously distributed around the mounting portion 521, or they can be multiple grooves spaced apart around the mounting portion 521. The at least one third glue groove is distributed along the axial direction of the mounting portion 521 (i.e., the direction in which the mounting portion 521 and the mounting hole 325 are installed). Each third glue groove is filled with sealant to increase the volume of sealant between the mounting portion 521 and the mounting hole 325, thereby improving the waterproof performance between the mounting portion 521 and the mounting hole 325. The at least one third glue groove can be any number, such as 1, 2, 3, 5, 7, etc., without limitation herein. It should be noted that when the sealant between the mounting portion 521 and the mounting hole 325 overflows in the installation direction, the third glue groove is considered to be filled with sealant.

[0070] The sealant between the mounting portion 521 and the mounting hole 325 not only seals the mounting portion 521 and the mounting hole 325 but also secures the mounting portion 521 and the mounting hole 325. The quality of the adhesive bond affects the sealing performance of the sealant. If the sealant is not firmly bonded and falls off, the sealing effect of the sealant may also be lost. The sealant can be used to bond the outer surface of the mounting portion 521 to the inner surface of the mounting hole 325. The quality of the bond between the outer surface of the mounting portion 521 and the inner surface of the mounting hole 325 can be determined by measuring the bond strength. The bond strength is the stress required to break the sealant adhesive system. The bond strength depends on factors such as the mechanical properties of the adhesive, the bonding process, the roughness of the inner surface of the mounting hole 325, and the roughness of the outer surface of the mounting portion 521. Excessively large surface roughness can result in excessive surface gaps, making it difficult for the sealant to fill the gaps, resulting in low bond strength and poor sealing. If the roughness is too small, the contact area between the sealant and the surface of the object will be reduced, and the sealant will be difficult to combine with the surface of the object, thereby reducing the bonding strength. Therefore, controlling the surface roughness within a reasonable range can increase the contact range between the surface of the object and the sealant, thereby increasing the bonding strength and further improving the sealing effect of the sealant. Therefore, the roughness of the inner surface of the mounting hole 325 and the outer surface of the mounting portion 521 can be greater than a preset first threshold. The first threshold includes the minimum roughness value required for the sealant to adhere firmly. In some embodiments, the surface roughness value for the sealant to adhere firmly can be a roughness range. At this time, the roughness of the inner surface of the mounting hole 325 and the outer surface of the mounting portion 521 can be within the roughness range.

[0071] The first threshold value can be determined based on the required bonding strength between the outer surface of the mounting portion 521 and the inner surface of the mounting hole 325, the mechanical properties of the adhesive, and the bonding process. In some embodiments, the first threshold value can be obtained experimentally. In some embodiments, the first threshold value can be obtained statistically. In some embodiments, the first threshold value can be obtained empirically.

[0072] In some embodiments, the first threshold can be obtained experimentally. Furthermore, when the mounting hole 325 and the mounting portion 521 are assembled and bonded with sealant, the first threshold can be indirectly measured through airtightness. Specifically, using the entire waterproof earphone 001 as a sample, a certain pressure is applied, and the pressure change is monitored. Using an airtightness tester, the degree of leakage can be accurately measured, providing accurate results without damaging the product. In some embodiments, when the mounting hole 325 and the mounting portion 521 are assembled and bonded with sealant, the first threshold can be tested using a positive pressure method. Specifically, using the entire waterproof earphone 001 as a sample, the sample is placed in a sealed cavity. The sealed cavity is divided into two layers, the upper layer containing air and the lower layer containing water. When the sample is placed in the sealed cavity, it is first placed in the upper layer of the sealed cavity, and a certain air pressure (e.g., 300 kPa) is applied to the upper layer. The sample is then immersed in water, and the upper layer pressure is released. At this time, if there is a leak in the product, the internal air pressure of the product will be high and bubbles will appear in the water. If there is no leak in the product, no bubbles will appear, thereby judging the overall sealing performance of the sample.

[0073] In some embodiments, when the mounting hole 325 and the mounting portion 521 have been assembled and bonded with sealant, the first threshold value is to directly put the waterproof earphones 001 into water and disassemble them to confirm whether water has entered.

[0074] In some embodiments, the first threshold can be obtained statistically. Furthermore, when the mounting hole 325 and the mounting portion 521 are assembled and bonded with sealant, the first threshold can be determined by setting up multiple mounting portions 521 and mounting holes 325 with different roughness values ​​and measuring the bonding strength multiple times to determine the first threshold required for a secure sealant bond. Specifically, within a sampling length, the stress required to destroy the sealing adhesive system at the bonding point between the mounting portion 521 and the mounting hole 325 with multiple different roughness values ​​is measured. The stress is compared and the roughness value at the inflection point of the increase is taken as the first threshold. The sampling length is selected based on the actual surface formation and texture characteristics of the inner surface of the mounting hole 325 and the outer surface of the mounting portion 521, reflecting the surface roughness characteristics. The sampling length is measured based on the actual direction of water after water ingress. For example, the sampling length can be selected 3-5 cm away from one end of the chamber body 320. The sample is the removed, cut portion.

[0075] In some embodiments, the first threshold value can be obtained through empirical analysis. Furthermore, the first threshold value between the mounting hole 325 and the mounting portion 521 can be inferred based on factors such as machining accuracy, adhesive strength, and contact area. Those skilled in the art will appreciate that other methods for measuring the first threshold value are also within the scope of this specification.

[0076] In some embodiments, the mounting hole 325 may further include a first slot. The buckle 580 is inserted into the first slot and the second slot 521 - 1 , thereby achieving connection between the connector 520 and the hopper body 320 and improving the connection strength between the connector 520 and the hopper body 320 .

[0077] The housing 320 also includes a water retaining portion 327. The water retaining portion 327 is located at the end of the mounting hole 325 and is spaced relative to the end of the connector 520. For example, the water retaining portion 327 is located at the end of the mounting hole 325 on the side away from the connector 520 and is spaced relative to the end of the mounting portion 521 of the connector 520. The water retaining portion 327 protrudes toward the center of the mounting hole 325 relative to the mounting hole 325. A through hole 327-1 is provided on the water retaining portion 327. After the cable 540 passes through the connecting hole 525, it passes through the through hole 327-1 and enters the interior of the housing 320 to achieve electrical connection with the electronic component 340. In some embodiments, the cable 540 and the through hole 327-1 are sealed by a sealant to strengthen the connection between the cable 540 and the through hole 327-1 and improve the waterproof performance of the waterproof earphones 001.

[0078] In some embodiments, the space between the water retaining portion 327 and the mounting portion 521 is filled with sealant. The sealant between the water retaining portion 327 and the mounting portion 521 surrounds the portion of the cable 540 located between the mounting portion 521 and the water retaining portion 327, thereby preventing external water from entering the interior of the silo 320 through the gap between the cable 540 and the through-hole 327-1 at the connection between the water retaining portion 327 and the mounting portion 521. As previously described, the water inlet path includes the connection between the connector 520 and the silo 320. Specifically, the connection between the connector 520 and the silo 320 may include the connection between the mounting portion 521 and the mounting hole 325 and the connection between the water retaining portion 327 and the mounting portion 521. The sealant between the water retaining portion 327 and the mounting portion 521 extends the water inlet path at the connection between the connector 520 and the silo 320, thereby improving the waterproof performance of the connection between the connector 520 and the silo 320.

[0079] In some embodiments, at least one first glue groove 327-3 is disposed on the side of the water retaining portion 327 facing the mounting portion 521. The at least one first glue groove 327-3 is filled with sealant. Each of the at least one first glue groove 327-3 can be disposed around the through hole 327-1. The first glue grooves 327-3 can be continuously disposed around the through hole 327-1, or they can be multiple grooves spaced apart around the through hole 327-1. Each first glue groove 327-3 is filled with sealant to increase the volume of sealant between the water retaining portion 327 and the mounting portion 521, thereby improving the waterproofing between the water retaining portion 327 and the mounting portion 521. The at least one first glue groove 327-3 can be distributed radially relative to the through hole 327-1. The number of the at least one first glue groove 327-3 can be any number, such as one, two, three, five, or seven, without limitation. It should be noted that, when the sealant filled between the water retaining portion 327 and the installation portion 521 overflows along the installation direction, it can be considered that the third sealant storage groove is filled with the sealant.

[0080] As mentioned above, when the connector 520 is installed with the warehouse body 320, the warehouse body 320 can abut against the raised portion 523 of the connector 520. Specifically, the end of the warehouse body 320 can abut against the raised portion 523. The space between the warehouse body 320 and the raised portion 523 is filled with sealant to achieve a sealed connection. As mentioned above, the water inlet path includes the connection between the connector 520 and the warehouse body 320. Specifically, the connection between the connector 520 and the warehouse body 320 can also include the connection between the warehouse body 320 and the raised portion 523. The sealant between the warehouse body 320 and the raised portion 523 extends the water inlet path at the connection between the connector 520 and the warehouse body 320, thereby improving the waterproof performance of the connection between the connector 520 and the warehouse body 320.

[0081] In some embodiments, in order to further improve the waterproof performance of the connection between the warehouse body 320 and the raised portion 523, the raised portion 523 may be provided with a boss. The boss protrudes toward the warehouse body 320. Accordingly, a groove may be provided at the end of the warehouse body 320 facing the raised portion 523. The shape, size and position of the groove match those of the boss. When the connector 520 is connected to the warehouse body 320, the end of the warehouse body 320 rests against the raised portion 523, and the boss is inserted into the groove. It should be noted that in some embodiments, the boss may be provided at the end of the warehouse body 320 facing the raised portion 523, and the groove may be provided at the end of the raised portion 523 facing the warehouse body 320. As previously mentioned, the space between the warehouse body 320 and the raised portion 523 is filled with sealant for a sealed connection. At this time, the space between the boss and the groove is also filled with sealant for a sealed connection. The structure of the boss and groove can increase the connection area between the warehouse body 320 and the raised portion 523, thereby extending the length of the water inlet path at the connection between the warehouse body 320 and the raised portion 523, thereby increasing the water inlet resistance and further improving the waterproof performance of the connection between the warehouse body 320 and the raised portion 523.

[0082] In some embodiments, to further enhance the waterproofing of the connection between the housing 320 and the raised portion 523, at least one second glue groove is provided on the side of the raised portion 523 facing the housing 320. Each of the at least one second glue groove surrounds the mounting portion 521. The second glue grooves can be continuous around the mounting portion 521, or they can be multiple grooves spaced apart. Each second glue groove is filled with sealant to increase the volume of sealant between the housing 320 and the raised portion 523, thereby enhancing the waterproofing between the housing 320 and the raised portion 523. The at least one second glue groove can be distributed radially along the mounting portion 521. The number of at least one second glue groove can be one, two, three, five, seven, or any other number, without limitation. It should be noted that when the sealant between the housing 320 and the raised portion 523 overflows in the installation direction, the third glue groove is considered fully filled with sealant.

[0083] As can be seen, the water inlet path at the junction of the housing 320 and the connector 520 includes, from the outside inward, the connection between the raised portion 523 and the end of the housing 320, the connection between the mounting portion 521 and the mounting hole 325, and the connection between the water retaining portion 327 and the end of the mounting portion 521. Furthermore, the directions of the water inlet paths at these three junctions are different. Therefore, by filling the junction between the housing 320 and the connector 520 with sealant, the waterproof earphones 001 further extend the length of the water inlet path and change its direction, thereby increasing water inlet resistance and improving the waterproof performance of the waterproof earphones 001.

[0084] When the outer surface of the warehouse body 320 is covered by the first protective cover 350 and the second protective cover 550, the first protective cover 350 and the second protective cover 550 are in contact with each other, and the contact point is sealed by a sealant. As mentioned above, the bonding strength between the outer surface of the warehouse body 320 and the first protective cover 350 and the second protective cover 550 may affect the sealing performance of the sealant between the outer surface of the warehouse body 320 and the first protective cover 350 and the second protective cover 550. Therefore, in order to improve the sealing performance between the outer surface of the warehouse body 320 and the first protective cover 350 and the second protective cover 550, the roughness of the outer surface of the warehouse body 320 is greater than the aforementioned first threshold. The first threshold and the method for measuring the roughness of the outer surface of the warehouse body 320 will not be repeated here.

[0085] The length of the second protective cover 550 covering the housing 320 can be any length. In some embodiments, the length of the second protective cover 550 covering the housing 320 is greater than the length of the connection between the mounting hole 325 and the mounting portion 521. This extends the length of the second protective cover 550 covering the outer surface of the housing 320, thereby extending the water inlet path, increasing water inlet resistance, and further improving waterproof performance.

[0086] The sealants used for the above bonding include instant glue (such as 502 glue), epoxy resin bonding, anaerobic glue, UV glue (ultraviolet light curing type), hot melt adhesive, pressure sensitive adhesive, latex, etc.

[0087] In summary, the waterproof electronic device provided in this specification provides a connector 520 to wrap the cable 540, and seals the connector 520 with the housing 320, replacing the direct connection of the cable 540 with the housing 320. This allows the connector 520 to be reliably sealed with the housing 320, thereby improving the waterproof effect of the waterproof earphones 001. In addition, the connection position between the connector 520 and the housing 320 is located before the connection position between the cable 540 and the housing 320. When external water penetrates into the waterproof earphones 001, it must first pass through the sealed connection between the connector 520 and the housing 320 before reaching the connection between the cable 540 and the housing 320. This increases the waterproof protection of the connection between the cable 540 and the housing 320, thereby improving the waterproof effect of the connection between the cable 540 and the housing 320. At the same time, the waterproof earphones 001 extend the water inlet path by extending the second protective cover 550 toward the housing 320 and at least partially covering the outer surface of the housing 320, thereby increasing the water inlet resistance and improving the waterproof effect.
