[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] Waterproof earphones, particularly those using electrical signal processing, achieve waterproofing by applying waterproof glue to the joint between the upper and lower housings of the core assembly. This method, however, results in a small amount of glue and a short path for the glue reservoir, resulting in poor waterproofing. This is particularly true when swimming, as waterproof earphones are subject to the intense pressure of water. This pressure can cause water to enter the earphones through the gap between the upper and lower housings, corroding circuit components.

[0036] The present application provides a core assembly for waterproof headphones and waterproof headphones, which increase the adhesive path of the waterproof headphones and improve the waterproof performance of the waterproof headphones. The waterproof headphones can be of any type. For example, the waterproof headphones 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 the 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, thereby stimulating the cochlear cochlear organ to produce hearing. For another example, the waterproof headphones can be a combination of air conduction headphones and bone conduction headphones. In some embodiments, the waterproof earphones may also include a data storage unit. In this case, the waterproof earphones can be independent of an external media player and, even when not transmitting signals to an external media player, can still play audio data stored in the built-in data storage unit. This specification does not limit the type of waterproof earphones.

[0037] Figure 1 shows a schematic structural diagram of a waterproof headset 001 provided according to some exemplary embodiments of the present application. As shown in Figure 1, the waterproof headset 001 may include a core assembly 100 and an ear hook assembly 300. In some embodiments, the waterproof headset 001 may also include a back hook assembly 500.

[0038] The core assembly 100 can also be called a speaker assembly. The core assembly 100 can convert electrical signals into sound signals that can be heard by humans. The number of core assemblies 100 can be one or two. When there is only one core assembly 100, the waterproof earphones 001 can be used in some application scenarios where stereo requirements are not particularly high, such as hearing aids for hearing-impaired patients, live broadcast prompting by hosts, etc. When the user wears the waterproof earphones 001, the core assembly 100 can be worn on the user's left ear or the user's right ear. When there are two core assemblies 100, when the user wears the waterproof earphones 001, the two core assemblies 100 are worn on different ears of the user respectively. At this time, both core assemblies 100 can make sound, so that the waterproof earphones 001 have stereo sound effects, improving the user's favorability of the waterproof earphones 001. In some embodiments, the two core assemblies 100 can be set 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 the back-hanging 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.

[0039] The ear hook assembly 300 can be electrically connected to the core assembly 100 to achieve control of the core assembly 100. In some embodiments, the ear hook assembly 300 can receive electrical signals sent by an external media player and send the electrical signals to the core assembly 100. In some embodiments, the ear hook assembly 300 can have a built-in data storage unit. In this case, the ear hook assembly 300 can send audio data from the built-in data storage unit to the core assembly 100. The number of ear hook assemblies 300 can be one or two. In some embodiments, each core assembly 100 can be connected to an ear hook assembly 300. In some embodiments, two core assemblies 100 can share one ear hook assembly 300. When the waterproof earphones 001 include two core assemblies 100 and two ear hook assemblies 300, the two core assemblies 100 are electrically connected to the two ear hook assemblies 300, respectively. In this case, the two ear hook assemblies 300 can be independently set to independently achieve control of the core assembly 100. The two ear hook components 300 can also be connected together, for example, by connecting the two ear hook components 300 together through the rear hanging component 500 to achieve unified control of the two core components 100.

[0040] In some embodiments, the waterproof earphones 001 may further include a rear hanging component 500. The rear hanging component 500 may connect the two core components 100. For example, when the two core components 100 are electrically connected to the two ear hanging components 300 respectively, the rear hanging component 500 may electrically connect the two ear hanging components 300. For another example, when the two core components 100 share one ear hanging component 300, the ear hanging component 300 may be close to any one of the two core components 100, and the rear hanging component 500 may electrically connect the ear hanging component 300 to the other of the two core components 100.

[0041] In some embodiments, the rear hanging component 500 may include a cable. The cable may be any conductive wire, such as a wire. The cable is mainly used to achieve electrical connection between the various electronic components of the waterproof earphones 001. For example, when two core components 100 are electrically connected to two ear hook components 300 respectively, the cable can electrically connect the two ear hook components 300. For another example, when two core components 100 share one ear hook component 300, the ear hook component 300 can be close to any one of the two core components 100, and the cable can electrically connect the ear hook component 300 to the other core component 100. The cable may be one strand or multiple strands. When there are multiple circuits that need to be electrically connected in the waterproof earphones 001, the cable can be set to multiple strands accordingly. For example, the cable can be set to any number of strands, such as 1 strand, 2 strands, 3 strands, 5 strands, 6 strands, 8 strands, etc.

[0042] In some embodiments, the rear hanging component 500 may also include an elastic metal wire. The elastic metal wire can be designed in an arc shape to provide a certain clamping force for the user when wearing the headphones. For example, when the two core components 100 are electrically connected to the two ear hook components 300 respectively, the two ends of the elastic metal wire can be connected to the two ear hook components 300 respectively. At this time, when the user wears the waterproof headphones 001, the two ear hook components 300 can be hung on the outside of the user's two ears respectively, and the rear hanging component 500 is used to be wrapped around the back of the user's head, and the two core components 100 are respectively located near the two ears. At this time, the elastic metal wire can provide a certain clamping force, so that the two core components 100 are close to the user's skin to improve wearing reliability.

[0043] In some embodiments, the waterproof earphones 001 may further include a protective cover. The protective cover may be coated on the outer surface of the core assembly 100. The protective cover may also be coated on the outer surface of the ear hook assembly 500. The protective cover may also be coated on the outer surface of the rear hanging assembly 500. The protective cover may be integrally formed or may be formed by splicing multiple protective covers. The protective cover may be sealed to the core assembly 100, the ear hook assembly 300 and the rear hanging assembly 500 by sealant to enhance the waterproof performance of the waterproof earphones 001. The protective cover may be made of a soft material with a certain degree of elasticity, such as soft silicone, rubber, etc.

[0044] It should be noted that the connection between the core assembly 100 and the ear hook assembly 300 can also be sealed with sealant to improve the waterproof performance of the waterproof earphone 001. Similarly, the connection between the ear hook assembly 300 and the back hanging assembly 500 can also be sealed with sealant to improve the waterproof performance of the waterproof earphone 001.

[0045] Figure 2 shows an exploded view of a waterproof headset 001 according to some exemplary embodiments of the present application. As shown in Figure 2 , the earhook assembly 300 may include a housing 320 and electronic components 340. The protective cover 600 shown in Figure 2 may be a protective cover covering the outer surface of the earhook assembly 300.

[0046] The housing 320 can serve as the mounting base for the earhook assembly 300. Other components of the earhook assembly 300, such as the electronic component 340, can be mounted on the housing 320. The housing 320 can include a main housing 321 and a housing cover 323. The main housing 321 and the housing cover 323 can be mounted together to form a storage compartment. For example, the electronic component 340 can be mounted within the housing 320, such as 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. The housing 320 can have any shape to accommodate the installation of other components. The housing 320 can be ergonomically designed to facilitate user use and data reading. The housing 320 can be made of any material, such as metal, plastic, polymer, etc. This specification does not limit the shape and material of the housing 320.

[0047] 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. The circuit board may control the core assembly 100. The circuit board is a chip integrated circuit with integrated headphone function. 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 Wifi, 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 can 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 circuit board (FPC), a rigid 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.

[0048] In some embodiments, the earhook assembly 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 a 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.

[0049] In some embodiments, the earhook assembly 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 via the circuit board to other components, such as the core assembly 100.

[0050] Figure 3 shows a front view of a movement assembly 100 according to some exemplary embodiments of the present application; Figure 4 shows an exploded view of the movement assembly 100 according to some exemplary embodiments of the present application; Figure 5 shows a cross-sectional view AA of the movement assembly 100 shown in Figure 3 of the present application; and Figure 6 shows a partially enlarged view J of the movement assembly 100 shown in Figure 5 of the present application. As shown in Figures 3 to 6, the movement assembly 100 includes a housing 120 and a movement module 140.

[0051] The housing 120 includes an upper housing 122 and a lower housing 124. These are thin-walled components. They connect to form a housing cavity 125. The movement module 140 is mounted within this cavity 125. The upper and lower housings 122, 124 are sealed to protect the movement module 140 from water and dust.

[0052] The movement module 140 includes a movement support 142 and a movement 144. Both the movement support 142 and the movement 144 are located within the accommodating cavity 125. The movement 144 is mounted on the movement support 142 and electrically connected to the circuit board via a cable. It receives electrical signals transmitted by the circuit board and converts them into audible sound waves.

[0053] In some embodiments, the movement 144 includes a bone conduction movement. The bone conduction movement may include a bone conduction transducer. The bone conduction transducer includes a vibrator. The bone conduction transducer can convert electrical signals into mechanical vibrations of the vibrator. The bone conduction transducer can be connected to the housing 120 through the movement bracket 142. When the waterproof earphones 001 are worn, the bone conduction movement can directly contact the user's skin (such as the cheek) through the housing 120, thereby conducting the mechanical vibrations to the user's skin, and transmitting through the user's skull to the cochlea to produce hearing. The bone conduction movement can enable the user to receive sound waves when the user's external auditory canal is open.

[0054] In some embodiments, the bone conduction movement may also include a diaphragm. The diaphragm is connected between the bone conduction transducer and the housing 120, dividing the accommodating chamber 125 into a front chamber near the skin contact area and a rear chamber away from the skin contact area. The housing 120 is provided with a sound outlet connected to the rear chamber. During relative motion between the bone conduction transducer and the housing 120, the diaphragm generates air-conducted sound, which is transmitted to the human ear through the sound outlet. In this manner, the movement 144 can generate both bone-conducted and air-conducted sound.

[0055] In some embodiments, the movement 144 includes an air conduction movement. The air conduction movement may include an air conduction transducer. The air conduction transducer can convert electrical signals into air vibrations. The air vibrations are transmitted to the user's ears through the sound outlet holes in the housing 120.

[0056] In some embodiments, the movement 144 includes both a bone conduction movement and an air conduction movement.

[0057] In addition, the core assembly 100 described in the present application may further include a microphone, a pickup, or other such microphone. For example, the microphone, the pickup, or other such microphone may be installed in the accommodating cavity 125 .

[0058] During the molding stage, the upper shell 122, the lower shell 124 and the movement bracket 142 can be molded as one piece, or they can be molded separately and then assembled together. Among them, the integral molding can adopt injection molding, stamping, die-casting and other processes to directly mold the upper shell 122, the lower shell 124 and the movement bracket 142 on the periphery of the movement 144. When molding separately, the upper shell 122, the lower shell 124 and the movement bracket 142 can be molded separately first, and then the lower shell 124 and the movement bracket 142 are connected together, and then connected to the upper shell 122. Among them, when molding separately, the upper shell 122, the lower shell 124 and the movement bracket 142 are sealed and connected by sealant to enhance the waterproof effect of the movement assembly 100. For the convenience of demonstration, the following content is described as an example in which the upper shell 122, the lower shell 124 and the movement bracket 142 are molded separately and then assembled together.

[0059] As shown in Figures 4 and 6, when the upper housing 122, lower housing 124, and movement bracket 142 are connected, a gap is provided at the connection between the upper housing 122, lower housing 124, and movement bracket 142 to form a glue groove 160. The glue groove 160 includes at least two intersecting paths. To enhance the waterproof performance of the movement assembly 100, the glue groove 160 is filled with sealant for sealing.

[0060] The lower shell 124 may include a first mounting portion 124-1. The first mounting portion 124-1 is used for mounting with the upper shell 122. The first mounting portion 124-1 is located at the end of the lower shell 124 on the side facing the upper shell 122. As mentioned above, the lower shell 124 is a thin-walled part. The first mounting portion 124-1 is continuously and closed along the circumference of the lower shell 124 to achieve a sealed connection with the upper shell 122. It should be noted that the circumferential continuity can be that the first mounting portion 124-1 is continuous everywhere along the lower shell 124 without interruption, and the closed setting can be that the first mounting portion 124-1 is connected end to end along the lower shell 124 to form a circular closed portion.

[0061] The first mounting portion 124-1 may include a first mounting surface 124-12. The first mounting surface 124-12 faces the upper housing 122. The first mounting surface 124-12 may be a flat surface at the end of the first mounting portion 124-1 facing the upper housing 122. The first mounting surface 124-12 may be a continuous and closed surface along the circumference of the lower housing 124.

[0062] The first mounting portion 124-1 may further include a first sidewall 124-14. The first sidewall 124-14 intersects with the first mounting surface 124-12 and faces the accommodating cavity 125. The first sidewall 124-14 may be a continuous and closed surface along the circumference of the lower housing 124. The first mounting surface 124-12 and the first sidewall 124-14 are connected to form a portion of the thin wall of the lower housing 124.

[0063] The lower shell 124 may also include a third mounting portion 124-3. The movement bracket 142 may be mounted on the third mounting portion 124-3. The third mounting portion 124-3 is farther away from the upper shell 122 relative to the first mounting portion 124-1, and is closer to the center of the accommodating cavity 125. That is, the third mounting portion 124-3 is closer to the inside of the accommodating cavity 125 relative to the first mounting portion 124-1, and the width of the third mounting portion 124-3 along the circumferential direction of the shell is greater than the width of the first mounting portion 124-1 along the circumferential direction of the shell. The third mounting portion 124-3 is continuously and closed along the circumference of the lower shell 124 to achieve a sealed connection with the movement bracket 142. It should be noted that the circumferential continuity can be that the third mounting portion 124-3 is continuous everywhere along the lower shell 124 without interruption, and the closed setting can be that the third mounting portion 124-3 is connected end to end along the lower shell 124 to form a circular closed portion.

[0064] In some embodiments, the third mounting portion 124-3 may include a third mounting surface 124-3. The third mounting surface 124-3 may intersect with the first side wall 124-14 and face the upper shell 122. The third mounting surface 124-3 is away from the upper shell 122 relative to the first mounting surface 124-12. The third mounting surface 124-3 may be a surface that is continuous and closed along the circumference of the lower shell 124. When the movement bracket 142 is connected to the lower shell 124, the movement bracket 142 may be mounted on the third mounting surface 124-3. The movement bracket 142 and the third mounting surface 124-3 may be sealed by a sealant to improve the waterproof performance of the movement assembly 100.

[0065] The upper shell 122 may include a second mounting portion 122-2. The second mounting portion 122-2 is used to be mounted with the first mounting portion 124-1. The second mounting portion 122-2 is located at the end of the upper shell 122 on the side facing the lower shell 124. As mentioned above, the upper shell 122 is a thin-walled part. The second mounting portion 122-2 is continuously and closed along the circumference of the upper shell 122 to achieve a sealed connection with the lower shell 124. It should be noted that the circumferential continuity can be that the second mounting portion 122-2 is continuous everywhere along the upper shell 122 without any interruption, and the closed setting can be that the second mounting portion 122-2 is connected end to end along the upper shell 122 to form a circular ring-shaped closed portion.

[0066] The second mounting portion 122-2 may include a second mounting surface 122-22. The second mounting surface 122-22 faces the lower shell 124. The second mounting surface 122-22 may be a portion of a plane at the end of the second mounting portion 122-2 facing the lower shell 124. The second mounting surface 122-22 may be a surface that is continuous and closed along the circumference of the upper shell 122. When the upper shell 122 is connected to the lower shell 124, the first mounting surface 124-12 abuts against the second mounting surface 122-22. In order to prevent water from entering the interior of the accommodating cavity 125 from the abutment between the first mounting surface 124-12 and the second mounting surface 122-22, the first mounting surface 124-12 and the second mounting surface 122-22 are sealed by a sealant.

[0067] The second mounting portion 122-2 may further include a second sidewall 122-24. The second sidewall 122-24 intersects the second mounting surface 122-22 and faces away from the accommodating cavity 125. The second sidewall 122-24 may be a continuous and closed surface along the circumference of the upper housing 122. The second mounting surface 122-22 and the second sidewall 122-24 are connected to form a portion of the thin wall of the upper housing 122.

[0068] When the upper shell 122 is connected to the lower shell 124, the second side wall 122-24 is positioned opposite the first side wall 124-14. A first gap 161 exists between the second side wall 122-24 and the first side wall 124-14. As previously described, the glue storage groove 160 includes at least two intersecting paths. One of the at least two intersecting paths can be the first gap 161. That is, the glue storage groove 160 includes the first gap 161. The first gap 161 is filled with sealant to form a waterproof path and enhance the waterproof effect.

[0069] When the seal between the first mounting surface 124-12 and the second mounting surface 122-22 fails or has a leak, external water may penetrate into the first gap 161 from the abutment between the first mounting surface 124-12 and the second mounting surface 122-22. The first gap 161 is filled with sealant, which can prevent water from further penetrating into the interior of the housing 120, thereby improving the waterproof performance of the movement assembly 100.

[0070] The first gap 161 can be distributed along the circumference of the shell 120. The circumference of the shell 120 can be the circumference of the upper shell 122 or the circumference of the lower shell 124. The first gap 161 can be continuously distributed along the circumference of the shell 120. That is, the sealant contained in the first gap 161 can be continuously distributed along the circumference of the shell 120 to form a sealed connection between the first side wall 124-14 and the second side wall 122-24. For the convenience of description, we define the direction in which the first gap 161 is distributed along the circumference as the length direction of the first gap 161. We define the direction in which the first side wall 124-14 is opposite to the second side wall 122-24 as the width direction of the first gap 161. The width of the first gap 161 is W1. We define the arrangement direction of the upper shell 122 and the lower shell 124 as the depth direction of the first gap 161. The depth of the first gap 161 is H1. The depth direction of the first gap 161 can also be the direction in which the first side wall 124-14 extends toward the upper housing 122 or the direction in which the second side wall 122-24 extends toward the lower housing 124. It should be noted that the depth and width directions of the first gap 161 are determined based on the direction in which water travels. When water enters the interior of the movement assembly 100 from the outside, the water flows toward the interior of the housing 120 along the arrangement direction of the upper housing 122 and the lower housing 124. Therefore, we define the direction in which the water flows as the depth direction of the first gap 161. We define the direction perpendicular to the depth direction as the width direction.

[0071] The depth H1 of the first gap 161 can be equal to the width W1, or can be greater than the width W1 or less than the width W1. In some embodiments, the depth H1 of the first gap 161 is greater than the width W1 of the first gap 161. As mentioned above, the depth direction of the first gap 161 is the direction of water flow. Therefore, in the scenario of swimming or being caught in the rain for a long time, extending the depth H1 of the first gap 161 can extend the water inlet path, thereby increasing the resistance to water inlet and improving the waterproof effect. Moreover, reducing the width W1 of the first gap is also conducive to increasing the resistance to water inlet and improving the waterproof effect. At the same time, the depth H1 of the first gap 161 being greater than the width W1 of the first gap 161 can make it easier for the sealant to squeeze into the first gap 161, and at the same time, the sealant can more evenly fill the entire first gap 161, thereby further improving the waterproof effect.

[0072] Among them, the value range of depth H1 is 0.4mm to 6mm. Furthermore, the value range of depth H1 is 0.4mm to 4mm. If the depth H1 is too small, the length of the waterproof path will be too short, and the amount of sealant filled in the first gap 161 will be insufficient, resulting in poor waterproof effect. If the depth H1 is too long, it will affect the thickness or structural strength of the shell 124, and the sealant will not be able to fill the entire first gap 161. In addition, the range of width W1 can be 0.1mm to 0.5mm. Further, the range of width W1 can be 0.1mm to 0.3mm. If the width W1 is too small, the waterproof path will be too short, and the amount of sealant filled in the first gap 161 will be insufficient, and the sealant will not be able to overflow to the upper end of the first gap 161 and fill the entire first gap 161. If the width W1 is too long, it will affect the arrangement of components in the shell 124. Therefore, taking all factors into consideration, the value range of depth H1 and width W1 can be 4 to 6. Furthermore, the value range of the depth H1 and the width W1 may be 4.5 to 5.5.

[0073] To enhance the ease and accuracy of installation of the upper and lower housings 122 and 124, the upper housing 122 further includes a positioning portion 122-4. The positioning portion 122-4 can be used to position the upper and lower housings 122 and 124 during installation. The positioning portion 122-4 can be located on the second sidewall 122-24 and protrude away from the second sidewall 122-24. The size and shape of the positioning portion 122-4 can match the size and shape of the first sidewall 124-14. The end of the positioning portion 122-4 facing away from the second sidewall 122-24 can be configured as a surface parallel to the second sidewall 122-24, or as a surface at a predetermined angle to the second sidewall 122-24. When the end of the positioning portion 122-4 facing away from the second sidewall 122-24 forms an angle with the second sidewall 122-24, the positioning portion 122-4 can be more easily inserted into the lower housing 124, while also facilitating the sealant filling the entire sealant reservoir 160. When the upper housing 122 and the lower housing 124 are assembled, the positioning portion 122-4 can be snapped into the first side wall 124-14. The positioning portion 122-4 allows the upper housing 122 to be precisely assembled with the lower housing 124. In some embodiments, the positioning portion 122-4 has a notch at one end near the lower housing 124, allowing the positioning portion 122-4 to quickly and easily snap into the first side wall 124-14 when the upper and lower housings 122, 124 are assembled.

[0074] As mentioned above, the first gap 161 between the first side wall 124-14 and the second side wall 122-24 is filled with sealant to form a sealed connection, thereby forming a waterproof path. The positioning portion 122-4 is located on the second side wall 122-24. In other words, the positioning portion 122-4 is located in the first gap 161. In order to make the first gap 161 continuous and thus form a stable and reliable waterproof path, the positioning portion 122-4 cannot completely cover the second side wall 122-24. Therefore, the positioning portion 122-4 can be located near the second mounting surface 122-22. Moreover, in the direction in which the second side wall 122-24 extends toward the lower housing 124 (that is, in the depth direction of the first gap 161), the size of the second side wall 122-24 is larger than the size of the positioning portion 122-4. Therefore, in the depth direction of the first gap 161, the positioning portion 122-4 cannot completely cover the second side wall 122-24. Therefore, the second sidewall 122 - 24 is at least partially exposed outside the positioning portion 122 - 4 and forms the first gap 161 opposite to the first sidewall 124 - 14 .

[0075] Furthermore, to further increase the surface area and volume of first gap 161, positioning portion 122-4 can include multiple positioning blocks. These multiple positioning blocks are spaced apart along the circumference of housing 120 (and the circumference of upper housing 122). In this case, the area between the multiple positioning blocks is referred to as a portion of first gap 161 and is filled with sealant. Consequently, both the surface area and volume of first gap 161 can be increased, further enhancing waterproof performance.

[0076] The upper shell 122 may further include an end surface 122-6. End surface 122-6 may face the lower shell 124. End surface 122-6 may intersect with the second sidewall 122-24 and face the lower shell 124. End surface 122-6 may be a continuous and closed surface along the circumference of the upper shell 122. As previously described, the upper shell 122 is a thin-walled component. End surface 122-6 may be the end of the upper shell 122 facing the lower shell 124. As previously described, the movement bracket 142 is mounted within the accommodating cavity 125. A second gap 162 exists between end surface 122-6 and the movement bracket 142.

[0077] Specifically, movement bracket 142 may include a positioning end 142-3. When movement bracket 142 is mounted on third mounting portion 124-3, positioning end 142-3 of movement bracket 142 may be mounted on third mounting surface 124-3. Positioning end 142-3 of movement bracket 142 and third mounting surface 124-3 are sealed with a sealant to enhance the waterproof performance of movement assembly 100.

[0078] Positioning end 142-3 may include a first surface 142-33. First surface 142-33 may be a continuous and closed surface along the circumference of movement support 142. First surface 142-33 may face upper housing 122. First surface 142-33 may face end surface 122-6. A second gap 162 may be formed between first surface 142-33 and end surface 122-6. Second gap 162 is filled with sealant to form a waterproof path and enhance waterproofing.

[0079] As mentioned above, the glue storage groove 160 may include at least two intersecting paths. The intersecting paths may be paths that are connected but in different directions. The at least two intersecting paths may include a second gap 162. The second gap 162 may intersect with the first gap 161. That is, the second gap 162 is connected to the first gap 161, but in a different direction. The second gap 162 and the first gap 161 form a waterproof path to improve the waterproof effect. The waterproof path is the first gap 161 and the second gap 162 from the outside to the inside. When the seal of the first gap 161 fails or there is a leak, water will enter the second gap 162 from the first gap 161. The second gap 162 is filled with sealant, which can prevent water from continuing to penetrate into the interior of the shell 120, thereby improving the waterproof performance of the movement assembly 100.

[0080] The second gap 162 can be distributed along the circumference of the housing 120. The circumference of the housing 120 can be the circumference of the upper housing 122 or the circumference of the lower housing 124. The second gap 162 can be continuously distributed along the circumference of the housing 120. That is, the sealant contained in the second gap 162 can be continuously distributed along the circumference of the housing 120 to form a sealed connection between the end surface 122-6 and the first surface 142-31. For ease of description, the direction in which the second gap 162 is distributed along the circumference is defined as the length direction of the second gap 162. The direction in which the end surface 122-6 and the first surface 142-31 face each other is defined as the width direction of the second gap 162. The width of the second gap 162 is W2. The direction in which the end surface 122-6 and the first surface 142-31 extend from the outside toward the center is defined as the depth direction of the second gap 162. The depth of the second gap 162 is H2. The width W2 ranges from 0.05 mm to 0.2 mm. It should be noted that the depth and width of second gap 162 are determined based on the direction of water flow. When water enters movement assembly 100 from outside, it flows through first gap 161 and then, along the direction extending from the outside to the center of housing 120, flows into housing 120 along second gap 162. Therefore, the direction of water flow is defined as the depth direction of second gap 162. The direction perpendicular to the depth direction is defined as the width direction.

[0081] In some embodiments, the depth H1 of the first gap 161 is greater than the depth H2 of the second gap 162, so that the water inlet resistance of the first gap 161 is greater than the water inlet resistance of the second gap 162, thereby preventing water from easily entering the first gap 161 and thus the second gap 162. In some embodiments, the ratio H1 / H2 ranges from 2 to 3. Furthermore, the ratio H1 / H2 ranges from 2.5 to 3, thereby further improving the waterproof performance. It should be noted that the depth H1 of the first gap 161 being equal to the depth H2 of the second gap or less than the depth H2 of the second gap is also within the scope of protection of this specification, and both situations also have very good waterproof effects.

[0082] The depth H2 of the second gap 162 can be equal to the width W2, or can be greater than the width W2 or less than the width W2. In some embodiments, the depth H2 of the second gap 162 is greater than the width W2 of the second gap 162. As previously mentioned, the depth direction of the second gap 162 is the direction of water flow. Therefore, extending the depth H2 of the second gap 162 can extend the water inlet path, thereby increasing the resistance to water inlet and improving the waterproof effect. Moreover, reducing the width W2 of the second gap is also conducive to increasing the resistance to water inlet and improving the waterproof effect. At the same time, the depth H2 of the second gap 162 being greater than the width W2 of the second gap 162 can make it easier for the sealant to squeeze into the second gap 162, and at the same time, the sealant can more evenly fill the entire second gap 162, thereby further improving the waterproof effect.

[0083] To ensure the sealant filling amount and waterproof effect of the second gap, the width W2 ranges from 0.05 mm to 0.2 mm. Furthermore, the width W2 ranges from 0.1 mm to 0.2 mm. The ratio of the depth H2 to the width W2 ranges from 4 to 6.5. Furthermore, the ratio of the depth H2 to the width W2 ranges from 5.5 to 6.5.

[0084] As previously described, the glue groove 160 may include intersecting first and second gaps 161, 162. The first and second gaps 161, 162 have different depths, forming an L-shaped glue groove. Compared to a linear glue groove, the L-shaped groove increases water resistance by changing the direction of the water inlet path, while also facilitating sealant application, thereby enhancing waterproofing. In some embodiments, the width W1 of the first gap 161 may be greater than the width W2 of the second gap 162, making it easier for the sealant to squeeze from the second gap 162 into the first gap 161. In some embodiments, the ratio W1 / W2 may be in the range of 2-3. In some embodiments, the ratio W1 / W2 may be in the range of 1.5-2, allowing the sealant to completely fill both the first and second gaps 161, 162. It should be noted that the width W1 of the first gap 161 may be equal to or less than the width W2 of the second gap, and both scenarios also provide excellent waterproofing. In some embodiments, the depth H1 of the first gap 161 is greater than the depth H2 of the second gap 162, so that the water inlet resistance of the first gap 161 is greater than the water inlet resistance of the second gap 162. As a result, water is less likely to enter the first gap 161 and the second gap 162, thereby further improving the waterproof performance. It should be noted that the depth H1 of the first gap 161 being equal to the depth H2 of the second gap or less than the depth H2 of the second gap is also within the scope of protection of this specification, and both situations also have excellent waterproof effects.

[0085] Positioning end 142-3 may further include a second surface 142-33. Second surface 142-33 is distributed along the circumference of core support 142. When core support 142 is mounted on third mounting portion 124-3, second surface 142-33 may face first sidewall 124-14. In some embodiments, a third gap 163 exists between second surface 142-33 and first sidewall 124-14. Third gap 163 is filled with sealant.

[0086] As previously described, the glue storage groove 160 may include at least two intersecting paths. The intersecting paths may be connected but in different directions. The at least two intersecting paths may include a third gap 163. The third gap 163 may intersect with the second gap 162 and the first gap 161. That is, the third gap 163, the second gap 162, and the first gap 161 are connected. The first gap 161 and the third gap 163 are located on both sides of the second gap 162. In some embodiments, when the seal of the first gap 161 fails or there is a leak, water will flow from the first gap 161 along the depth direction of the first gap 161 into the third gap 163. The third gap 163 is filled with sealant, which can prevent water from further infiltrating into the interior of the movement assembly 100.

[0087] The third gap 163 can be distributed along the circumference of the shell 120. The circumference of the shell 120 can be the circumference of the upper shell 122 or the circumference of the lower shell 124. The third gap 163 can be distributed continuously along the circumference of the shell 120. That is, the sealant contained in the third gap 163 can be distributed continuously along the circumference of the shell 120 to form a sealed connection between the second surface 142-33 and the first sidewall 124-14. For convenience of description, we define the direction in which the third gap 163 is distributed along the circumference as the length direction of the third gap 163. We define the direction opposite to the second surface 142-33 and the first sidewall 124-14 as the width direction of the third gap 163. The width of the third gap 163 is W3. The direction in which the first sidewall 124-14 extends is defined as the depth direction of the third gap 163. The depth of the third gap 163 is H3. It should be noted that the depth and width directions of the third gap 163 are determined based on the direction of water flow. When water enters the interior of the core assembly 100 from the outside, it flows through the first gap 161 and then flows into the interior of the housing 120 along the direction of the first sidewall 124-14 (which is also the direction of arrangement of the upper housing 122 and the lower housing 124). Therefore, the direction of water flow is defined as the depth direction of the third gap 163. The direction perpendicular to the depth direction is defined as the width direction.

[0088] The depth H3 of the third gap 163 can be equal to the width W3, or can be greater than the width W3 or less than the width W3. In some embodiments, the depth H3 of the third gap 163 is greater than the width W3 of the third gap 163. As mentioned above, the depth direction of the third gap 163 is the direction of water flow. Therefore, extending the depth H3 of the third gap 163 can extend the water inlet path, thereby increasing the resistance to water inlet and improving the waterproof effect. Moreover, reducing the width W3 of the first gap is also conducive to increasing the resistance to water inlet and improving the waterproof effect. At the same time, the depth H3 of the third gap 163 being greater than the width W3 of the third gap 163 can make it easier for the sealant to squeeze into the third gap 163, and at the same time, the sealant can more evenly fill the entire third gap 163, thereby further improving the waterproof effect.

[0089] As previously described, the glue groove 160 may include a first gap 161, a second gap 162, and a third gap 163 that intersect. The first gap 161, the second gap 162, and the third gap 163 may form a T-shaped glue groove. By changing the direction and lengthening the water inlet path, the T-shaped glue groove can increase resistance to water inflow, thereby improving the waterproofing effect. Furthermore, the T-shaped glue groove can accommodate more sealant, allowing the sealant to fully fill the glue groove 160, further improving the waterproofing effect.

[0090] It should be noted that the term "filled" can be understood as the sealant being continuous along the length and width of the sealed object, thereby achieving a sealing effect. When there are multiple sealed objects and they are connected, "filled" can be understood as the sealant being continuous along the length and width of each of the multiple sealed objects, and the connections between the multiple sealed objects are also filled continuously with sealant, with no gaps left unfilled by the sealant.

[0091] It should be noted that the gap formed at the connection between the upper shell 122, the lower shell 124 and the movement bracket 142 can be considered as a part of the glue storage groove 160.

[0092] 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.

[0093] In summary, this specification provides a movement assembly 100 and a waterproof earphone 001, by setting a glue groove 160 formed by gaps in multiple directions at the connection between the upper shell 122, the lower shell 1224 and the movement bracket 142 of the movement assembly 100, so that the path of the glue groove 160 has multiple different directions. While extending the path of the glue groove 160 of the waterproof earphone 001, by changing the path direction of the glue groove 160, the glue groove 160 has multiple intersecting paths, which increases the resistance of external water entering the interior of the movement assembly 100, and further improves the waterproof performance of the movement assembly 100.
