Waterproof headphones in the related art of electric signals are waterproof by applying waterproof glue to the junction between the upper case and the lower case of the deck assembly. The mode has small glue storage amount, short path of glue storage groove and poor waterproof performance. Particularly in swimming situations, the waterproof earphone is subjected to liquid pressure from water, and under the action of the liquid pressure, the water can enter the earphone from the gap between the upper shell and the lower shell to erode circuit elements.

The application provides a core assembly of a waterproof earphone and the waterproof earphone, which increase the glue hiding path of the waterproof earphone and improve the waterproof performance of the waterproof earphone. The waterproof earphone can be any form of earphone. The waterproof earphone may be a wired earphone, for example. The receiver in the wired earphone can receive the electric signal sent by the media player in a wired transmission mode, so that the electric signal is converted into sound waves which can be heard by human ears. For example, the waterproof earphone may be a wireless earphone. The receiver in the wireless earphone can receive the electric signal sent by the media player in a wireless transmission mode, so that the electric signal is converted into sound waves which can be heard by human ears. The waterproof earphone may be an air conduction earphone. The air conduction earphone can convert the electric signal into an air vibration signal. The air vibration signal may be transmitted into the ear canal of the ear. The eardrum in the ear can convert the air vibration signal into sound. As another example, the waterproof earphone may be a bone conduction earphone. The bone conduction headphones may convert the electrical signals into mechanical vibration signals. The mechanical vibration signal can cause the vibration of the skull bone, cause the perilymph to generate fluctuation with the same frequency, and excite the spiral device of the cochlea to generate hearing. As another example, the waterproof earpiece may be a combination of an air conduction earpiece and a bone conduction earpiece. In some embodiments, the waterproof earphone may also include a data storage unit. At this time, the waterproof earphone may not depend on an external media player, and may play audio data stored in the built-in data storage unit when not transmitting signals with the external media player. The present specification does not limit the type of waterproof earphone.

Fig. 1 illustrates a schematic structural diagram of a waterproof earphone 001 provided according to some exemplary embodiments of the present application. As shown in fig. 1, the waterproof earphone 001 may include a deck assembly 100 and an ear-hook assembly 300. In some embodiments, the waterproof earphone 001 may further comprise a rear hanging assembly 500.

The engine assembly 100 may also be referred to as a speaker assembly. The cartridge assembly 100 may convert the electrical signal into an audible signal that may be heard by a person. The number of cartridge assemblies 100 may be one or two. When the movement assembly 100 is one, the waterproof earphone 001 may be suitable for use in some applications where the stereo requirements are not particularly high, such as hearing patient hearing aids, host direct broadcast word-making, and the like. When the waterproof earphone 001 is worn by the user, the deck assembly 100 may be worn on the left ear of the user or on the right ear of the user. When the deck assembly 100 is two, the two deck assemblies 100 are respectively worn at different ears of the user when the user wears the waterproof earphone 001. At this time, both the deck assemblies 100 can sound, thereby enabling the waterproof earphone 001 to have a stereo sound effect, improving the user's feeling of the waterproof earphone 001. In some embodiments, two cartridge assemblies 100 may be provided independently. I.e., the two deck assemblies 100 may exist independently and may be worn separately. For example, the two deck assemblies 100 may be worn on different ears, respectively, or on different user ears, respectively, making the use of the waterproof earphone 001 more flexible. At this time, the two deck assemblies 100 may operate independently. In some embodiments, two movement assemblies 100 may also be coupled together (e.g., via rear suspension assembly 500). At this time, the two deck assemblies 100 can operate simultaneously and can be uniformly controlled to obtain a better sound effect. In some embodiments, the cartridge assembly 100 may be an air conduction cartridge. At this time, the deck assembly 100 may be in-ear or open while the user wears the waterproof earphone 001. In some embodiments, cartridge assembly 100 may also be a bone conduction cartridge. At this time, the deck assembly 100 may be hung outside the user's ear while the user wears the waterproof earphone 001. For example, the deck assembly 100 may be hung outside the ear and placed against the skin of the human body to transmit sound waves into the interior of the ear through vibrations of the skin and bones of the human body. In some embodiments, cartridge assembly 100 may be a combination of an air-guided cartridge and a bone-guided cartridge.

The ear-hook assembly 300 may be electrically connected to the deck assembly 100 to enable control of the deck assembly 100. In some embodiments, the ear-hook assembly 300 may receive an electrical signal transmitted by an external media player and transmit the electrical signal to the deck assembly 100. In some embodiments, the ear-hook component 300 may incorporate a data storage unit. At this time, the ear-hook assembly 300 may transmit audio data of the built-in data storage unit to the deck assembly 100. The number of ear hook assemblies 300 can be one or two. In some embodiments, each cartridge assembly 100 may be coupled to one ear-hook assembly 300. In some embodiments, two cartridge assemblies 100 may share an ear-hook assembly 300. When the waterproof earphone 001 includes two deck assemblies 100 and two ear-hook assemblies 300, the two deck assemblies 100 are electrically connected to the two ear-hook assemblies 300, respectively. At this time, the two ear-hook assemblies 300 may be independently provided to independently enable control of the deck assembly 100. The two ear-hook assemblies 300 may also be connected together, such as by the rear-hook assembly 500 connecting the two ear-hook assemblies 300 together, to provide unified control of the two cartridge assemblies 100.

In some embodiments, the waterproof earphone 001 may further comprise a rear hanging assembly 500. The rear hitch assembly 500 may connect two movement assemblies 100. For example, when two deck assemblies 100 are electrically connected to two ear-hook assemblies 300, respectively, the rear-hook assembly 500 may electrically connect the two ear-hook assemblies 300. For another example, when two cartridge assemblies 100 share one ear-hook assembly 300, the ear-hook assembly 300 may be positioned adjacent to either of the two cartridge assemblies 100 and the rear-hook assembly 500 may electrically connect the ear-hook assembly 300 to the other of the two cartridge assemblies 100.

In some embodiments, rear hitch assembly 500 may include a cable. Wherein the cable may be any wire, such as a wire, that is electrically conductive. The cable is mainly used for realizing electric connection among various electronic components of the waterproof earphone 001. For example, when two deck assemblies 100 are electrically connected to two ear-hook assemblies 300, respectively, the cable may electrically connect the two ear-hook assemblies 300. For another example, when two cartridge assemblies 100 share one ear-hook assembly 300, the ear-hook assembly 300 may be positioned adjacent to either of the two cartridge assemblies 100, and the cable may electrically connect the ear-hook assembly 300 to the other cartridge assembly 100. The number of the cables can be one or more, and when the number of circuits to be electrically connected in the waterproof earphone 001 is multiple, the cables can be correspondingly arranged in a plurality of strands, for example, the cables can be arranged in any number of strands such as 1 strand, 2 strands, 3 strands, 5 strands, 6 strands, 8 strands and the like.

In some embodiments, rear hitch assembly 500 may also include a resilient wire. The elastic metal wire can be in an arc-shaped design, and a certain clamping force is provided for a user when the earphone is worn. For example, when two deck assemblies 100 are electrically connected to two ear-hook assemblies 300, respectively, both ends of the elastic wire may be connected to two ear-hook assemblies 300, respectively. At this time, when the user wears the waterproof earphone 001, the two ear-hanging assemblies 300 may be respectively hung on the outer sides of the two ears of the user, the rear-hanging assembly 500 is used to be wound around the rear side of the head of the user, and the two movement assemblies 100 are respectively located near the two ears. At this time, the elastic wire may provide a certain clamping force, so that the two movement assemblies 100 are abutted against the skin of the user, so as to improve wearing reliability.

In some embodiments, the waterproof earphone 001 may further comprise a protective sleeve. The protective sleeve may be wrapped around the exterior surface of the engine assembly 100. The protective sleeve may also be wrapped around the outer surface of the ear-hook assembly 500. The protective sleeve may also wrap around the outer surface of the rear hitch assembly 500. The protective sleeve can be integrally formed, or formed by splicing a plurality of protective sleeves. The protective sleeve and the deck assembly 100, the ear-hook assembly 300 and the rear-hook assembly 500 can be connected by sealing glue, so as to improve the waterproof performance of the waterproof earphone 001. The protective sleeve may be made of a soft material having a certain elasticity, such as soft silica gel, rubber, etc.

It should be noted that, the joint between the deck assembly 100 and the ear-hook assembly 300 may also be sealed by a sealant, so as to improve the waterproof performance of the waterproof earphone 001. Likewise, the connection between the ear-hook assembly 300 and the rear-hook assembly 500 can be sealed by sealant, so as to improve the waterproof performance of the waterproof earphone 001.

The second mounting portion 122-2 is continuously and closely disposed along the circumferential direction of the upper housing 122 to achieve a sealed connection with the lower housing 124. It should be noted that, the circumferential continuity may be that the second mounting portion 122-2 is continuous along the upper housing 122 without any discontinuity, and the sealing arrangement may be that the second mounting portion 122-2 is connected end to end along the upper housing 122 to form a circular sealing portion.

The second mounting portion 122-2 may include a second mounting surface 122-22. The second mounting face 122-22 faces the lower housing 124. The second mounting surface 122-22 may be a portion of a plane of an end of the second mounting portion 122-2 facing the lower housing 124. The second mounting surface 122-22 may be a continuous and closed surface along the circumference of the upper housing 122. When the upper case 122 is connected to the lower case 124, the first mounting surface 124-12 abuts the second mounting surface 122-22. In order to prevent water from entering the interior of the accommodating chamber 125 from the abutment of 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 sealingly connected by a sealant.

The second mounting portion 122-2 may also include a second sidewall 122-24. The second side wall 122-24 intersects the second mounting face 122-22 and faces away from the receiving cavity 125. The second side wall 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 side wall 122-24 are joined together to form a portion of the thin wall of the upper housing 122.

When the upper housing 122 is coupled to the lower housing 124, the second side wall 122-24 is disposed 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 reservoir 160 includes at least two intersecting paths. Wherein one of the at least two intersecting paths may be the first gap 161. I.e. the glue reservoir 160 comprises a first gap 161. The first gap 161 is filled with sealant, so as to form a waterproof path, and improve a waterproof effect.

When the seal between the first mounting surface 124-12 and the second mounting surface 122-22 fails or a leak exists, external water may infiltrate into the first gap 161 from the abutment of the first mounting surface 124-12 and the second mounting surface 122-22. And the first gap 161 is filled with sealant, so that water can be prevented from continuously penetrating into the interior of the case 120, thereby improving the waterproof performance of the movement assembly 100.

The first gaps 161 may be distributed along the circumferential direction of the housing 120. The circumference of the housing 120 may be the circumference of the upper housing 122 or the circumference of the lower housing 124. The first gaps 161 may be continuously distributed along the circumferential direction of the housing 120. That is, the sealant contained in the first gap 161 may be continuously distributed along the circumference of the housing 120 to form a sealed connection between the first and second sidewalls 124-14 and 122-24. For convenience of description, we define the direction in which the first gaps 161 are circumferentially distributed as the length direction of the first gaps 161. We define the direction of the first side wall 124-14 opposite 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 case 122 and the lower case 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 may be a direction in which the first side wall 124-14 extends toward the upper case 122 or a direction in which the second side wall 122-24 extends toward the lower case 124. The depth direction and the width direction of the first gap 161 are determined according to the direction in which water travels. When water enters the interior of the deck assembly 100 from the outside of the deck assembly 100, the water flows toward the inside of the case 120 along the arrangement direction of the upper case 122 and the lower case 124. Therefore, we define the direction of water flow travel as the depth direction of the first gap 161. We define the direction perpendicular to the depth direction as the width direction.

The depth H1 of the first gap 161 may be equal to the width W1, or may 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 described above, the depth direction of the first gap 161 is the direction in which the water flow travels. Therefore, in a swimming or long-term raining scene, extending the depth H1 of the first gap 161 may extend the water intake path, thereby increasing the resistance of the intake water and enhancing the waterproof effect. Moreover, the width W1 of the first gap is reduced, so that the resistance of water inflow is increased, and the waterproof effect is improved. Meanwhile, the depth H1 of the first gap 161 is greater than the width W1 of the first gap 161, so that the sealant can be more easily extruded into the first gap 161, and simultaneously, the sealant can be more uniformly filled in the whole first gap 161, thereby further improving the waterproof effect.

Wherein the depth H1 is in the range of 0.4mm to 6mm. Further, the depth H1 has a value ranging from 0.4mm to 4mm. Too small a depth H1 may result in too short a length of the waterproof path, and also may result in insufficient amount of sealant filled in the first gap 161, thereby resulting in poor waterproof effect. Too long a depth H1 may affect the thickness or structural strength of the housing 124, and may prevent the sealant from filling the entire first gap 161. Further, the width W1 may range from 0.1mm to 0.5mm. Further, the width W1 may range from 0.1mm to 0.3mm. Too small a width W1 may result in too short a waterproof path and also may result in insufficient amount of sealant filled in the first gap 161, and thus the sealant may not overflow to the upper end of the first gap 161 and fill the entire first gap 161. Too long a width W1 affects the arrangement of the components within the housing 124. Therefore, the depth H1 and the width W1 can be in the range of 4 to 6. Further, the depth H1 and the width W1 may have a value ranging from 4.5 to 5.5.

In order to improve the convenience and accuracy of the installation of the upper and lower cases 122 and 124, the upper case 122 further includes a positioning portion 122-4. The positioning portion 122-4 may be used for positioning when the upper case 122 is mounted with the lower case 124. The positioning portion 122-4 may be located on the second side wall 122-24 and protrude in a direction away from the second side wall 122-24. The size and shape of the positioning portion 122-4 may match the size and shape of the first sidewall 124-14. The end of the positioning portion 122-4 away from the second side wall 122-24 may be disposed as a surface parallel to the second side wall 122-24 or may be disposed as a surface having a certain angle with the second side wall 122-24. When an included angle is formed between the end of the positioning portion 122-4 away from the second side wall 122-24 and the second side wall 122-24, the positioning portion can be better clamped into the lower housing 124, and meanwhile, the sealant can be conveniently filled in the whole glue storage groove 160. When the upper housing 122 and the lower housing 124 are assembled, the positioning portion 122-4 can be snapped into the first sidewall 124-14. The upper case 122 can be precisely assembled with the lower case 124 by the positioning portion 122-4. In some embodiments, the positioning portion 122-4 has a notch at an end near the lower housing 124, so that the positioning portion 122-4 can be quickly and easily snapped into the first sidewall 124-14 when the upper housing 122 and the lower housing 124 are assembled.

As previously described, the first gap 161 between the first side wall 124-14 and the second side wall 122-24 is filled with a sealant to form a sealed connection, thereby forming a watertight path. And the positioning portion 122-4 is located on the second side wall 122-24. That is, the positioning portion 122-4 is located in the first gap 161. In order to make the first gap 161 continuous so as to form a stable and reliable waterproof path, the positioning portion 122-4 cannot completely cover the second side wall 122-24. Thus, the positioning portion 122-4 may be located near the second mounting surface 122-22. And, in the direction in which the second side wall 122-24 extends toward the lower case 124 (i.e., 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, the positioning portion 122-4 cannot completely cover the second side wall 122-24 in the depth direction of the first gap 161. Thus, the second side wall 122-24 is at least partially exposed outside the positioning portion 122-4 and forms the first gap 161 opposite to the first side wall 124-14.

In addition, in order to further increase the surface area and volume of the first gap 161, the positioning portion 122-4 may include a plurality of positioning blocks. The plurality of positioning blocks are disposed at intervals along the circumferential direction of the housing 120 (the circumferential direction of the upper housing 122). At this time, a portion between the plurality of positioning blocks is referred to as a portion of the first gap 161, and is filled with the sealant. Therefore, both the surface area and the volume of the first gap 161 can be increased, and the waterproof performance can be further improved.

The upper housing 122 may also include an end face 122-6. The end face 122-6 may face the lower housing 124. The end surface 122-6 may intersect the second side wall 122-24 and face the lower housing 124. The end face 122-6 may be a continuous and closed face along the circumference of the upper housing 122. As previously described, the upper housing 122 is a thin-walled part. The end surface 122-6 may be the end of the upper housing 122 facing the side of the lower housing 124. As described above, the deck bracket 142 is installed inside the accommodation chamber 125. A second gap 162 exists between end face 122-6 and deck support 142.

Specifically, deck support 142 may include positioning ends 142-3. When the deck bracket 142 is mounted with the third mounting portion 124-3, the positioning end 142-3 of the deck bracket 142 may be mounted on the third mounting surface 124-3. The positioning end 142-3 of the deck bracket 142 is sealingly coupled to the third mounting surface 124-3 by a sealant to enhance the waterproof performance of the deck assembly 100.

The locating end 142-3 may include a first surface 142-33. The first surfaces 142-33 may be continuous and closed surfaces along the circumference of the cartridge holder 142. The first surfaces 142-33 may be faces facing the upper housing 122. The first surface 142-33 may face the end face 122-6. A second gap 162 exists between first surface 142-33 and end surface 122-6. The second gap 162 is filled with sealant to form a waterproof path, thereby improving waterproof effect.

As previously described, the glue reservoir 160 may include at least two intersecting paths. The intersecting paths may be in communication with each other but in different directions. The at least two intersecting paths may include a second gap 162. The second gap 162 may intersect the first gap 161. I.e. the second gap 162 communicates with the first gap 161 and is differently oriented. The second gap 162 and the first gap 161 form a waterproof path, thereby enhancing waterproof effect. The waterproof path is a first gap 161 and a second gap 162 in this order from the outside to the inside. When the seal of the first gap 161 fails or a leak exists, water may enter the second gap 162 from the first gap 161. And the second gap 162 is filled with sealant, so that water can be prevented from continuously penetrating into the interior of the casing 120, thereby improving the waterproof performance of the movement assembly 100.

The second gaps 162 may be distributed along the circumferential direction of the housing 120. The circumference of the housing 120 may be the circumference of the upper housing 122 or the circumference of the lower housing 124. The second gaps 162 may be continuously distributed along the circumferential direction of the housing 120. That is, the sealant contained in the second gap 162 may be continuously distributed along the circumference of the housing 120 to form a sealed connection between the end face 122-6 and the first surface 142-31. For convenience of description, we define the direction in which the second gaps 162 are circumferentially distributed as the length direction of the second gaps 162. We define the direction of the end face 122-6 opposite the first surface 142-31 as the width direction of the second gap 162. The width of the second gap 162 is W2. We define the direction in which the end face 122-6 and the first surface 142-31 extend from the outside toward the center as the depth direction of the second gap 162. The depth of the second gap 162 is H2.. The depth direction and the width direction of the second gap 162 are determined according to the direction in which water travels. When water enters the interior of the deck assembly 100 from the outside of the deck assembly 100, the water flows through the first gap 161 and then flows into the interior of the housing 120 along the second gap 162 in a direction in which the housing 120 extends from the outside toward the center. Thus, we define the direction of water flow travel as the depth direction of the second gap 162. We define the direction perpendicular to the depth direction as the width direction.

In some embodiments, the depth H1 of the first gap 161 is greater than the depth H2 of the second gap 162, such that the water intake resistance of the first gap 161 is greater than the water intake resistance of the second gap 162, such that water does not easily enter the first gap 161, i.e., does not easily enter the second gap 162. In some embodiments, H1/H2 ranges from 2 to 3. Further, the range of H1/H2 is 2.5 to 3, thereby better improving the waterproof performance. It should be noted that, the depth H1 of the first gap 161 is equal to the depth H2 of the second gap or smaller than the depth H2 of the second gap is also within the protection scope of the present specification, and both cases have very good waterproof effect.

The depth H2 of the second gap 162 may be equal to the width W2, or may 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 described, the depth direction of the second gap 162 is the direction in which the water flow travels. Therefore, extending the depth H2 of the second gap 162 may extend the water inlet path, thereby increasing the resistance to water inlet and enhancing the waterproof effect. Moreover, the width W2 of the second gap is reduced, so that the resistance of water inflow is increased, and the waterproof effect is improved. Meanwhile, the depth H2 of the second gap 162 is greater than the width W2 of the second gap 162, so that the sealant can be more easily extruded into the second gap 162, and the sealant can be more uniformly filled in the whole second gap 162, thereby further improving the waterproof effect.

Wherein, in order to ensure the sealant filling amount of the second gap and the waterproof effect, the width W2 is in the range of 0.05mm to 0.2mm. Further, the width W2 ranges from 0.1mm to 0.2mm. The ratio of depth H2 to width W2 ranges from 4 to 6.5. Further, the ratio of the depth H2 to the width W2 is in the range of 5.5-6.5.

As previously described, the glue slot 160 may include a first gap 161 and a second gap 162 that intersect. The depth directions of the first gap 161 and the second gap 162 are different, so that the first gap 161 and the second gap 162 form an L-shaped glue storage groove. Compared with the linear type glue hiding groove, the L-shaped glue hiding groove can increase the water inlet resistance by changing the direction of the water inlet path, and meanwhile, glue is conveniently beaten, so that the waterproof effect is improved. In some embodiments, the width W1 of the first gap 161 may be greater than the width W2 of the second gap 162, such that the sealant is more easily squeezed into the first gap 161 from the second gap 162. In some embodiments, W1/W2 may range from 2 to 3. In some embodiments, W1/W2 may range from 1.5 to 2, such that the sealant may fill the first gap 161 and the second gap 162. It should be noted that, the width W1 of the first gap 161 is equal to the width W2 of the second gap or smaller than the width W2 of the second gap is also within the protection scope of the present specification, and both cases have very good waterproof effect.

The locating end 142-3 may also include a second surface 142-33. The second surfaces 142-33 are distributed along the circumference of the deck support 142. The second surface 142-33 may face the first side wall 124-14 when the deck bracket 142 is mounted on the third mounting portion 124-3. In some embodiments, a third gap 163 exists between the second surfaces 142-33 and the first sidewalls 124-14. The third gap 163 is filled with sealant.

As previously described, the glue reservoir 160 may include at least two intersecting paths. The intersecting paths may be in communication with each other but in different directions. The at least two intersecting paths may include a third gap 163. The third gap 163 may intersect the second gap 162 and the first gap 161. Namely, the third gap 163, the second gap 162, and the first gap 161 communicate. The first gap 161 and the third gap 163 are located at both sides of the second gap 162. In some embodiments, when the seal of the first gap 161 fails or a leak exists, water may flow from the first gap 161 into the third gap 163 in the depth direction of the first gap 161. And the third gap 163 is filled with sealant, which prevents water from continuing to permeate into the interior of the engine assembly 100.

The third gaps 163 may be distributed along the circumferential direction of the housing 120. The circumference of the housing 120 may be the circumference of the upper housing 122 or the circumference of the lower housing 124. The third gaps 163 may be continuously distributed along the circumferential direction of the housing 120. That is, the sealant contained in the third gap 163 may be continuously distributed along the circumference of the housing 120 to form a sealed connection between the second surfaces 142-33 and the first sidewalls 124-14. For convenience of description, we define the direction in which the third gaps 163 are distributed in the circumferential direction as the length direction of the third gaps 163. We define the direction of the second surface 142-33 opposite the first sidewall 124-14 as the width direction of the third gap 163. The width of the third gap 163 is W3. We define the direction in which the first sidewalls 124-14 extend as the depth direction of the third gap 163. The third gap 163 has a depth H3. The depth direction and the width direction of the third gap 163 are determined according to the direction in which water travels. When water enters the interior of the engine assembly 100 from the outside of the engine assembly 100, the water flows through the first gap 161 toward the inside of the housing 120 along the direction in which the first side wall 124-14 extends (also the direction in which the upper and lower housings 122 and 124 are aligned). Therefore, we define the direction in which the water flow travels as the depth direction of the third gap 163. We define the direction perpendicular to the depth direction as the width direction.

The depth H3 of the third gap 163 may be equal to the width W3, or may 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 described above, the depth direction of the third gap 163 is the direction in which the water flow travels. Therefore, extending the depth H3 of the third gap 163 may extend the water inlet path, thereby increasing the resistance to water inlet and enhancing the waterproof effect. Moreover, the width W3 of the first gap is reduced, so that the resistance of water inflow is increased, and the waterproof effect is improved. Meanwhile, the depth H3 of the third gap 163 is greater than the width W3 of the third gap 163, so that the sealant can be more easily extruded into the third gap 163, and simultaneously, the sealant can be more uniformly filled in the whole third gap 163, thereby further improving the waterproof effect.

As previously described, the glue groove 160 may include intersecting first, second and third gaps 161, 162, 163. The first, second and third gaps 161, 162 and 163 may form a T-shaped glue groove. The T-shaped glue storage groove can increase the resistance of water inlet by changing the direction of the water inlet path and prolonging the water inlet path, so that the waterproof effect is improved. Meanwhile, more sealant can be contained in the T-shaped glue storage groove, so that the sealant can fully fill the glue storage groove 160, and the waterproof effect is further improved.

The filling is understood to mean that the sealant is continuous in the length and width directions of the object to be sealed, thereby achieving the sealing effect. When the plurality of objects to be sealed are in a communicating relationship, filling can be understood as that the sealant is continuous in the length and width directions of each of the plurality of objects to be sealed, and the joints between the plurality of objects to be sealed are also filled continuously with the sealant, and there is no gap not filled with the sealant.

Note that, the gap formed at the connection of the upper case 122, the lower case 124, and the deck support 142 may be considered as a part of the glue reservoir 160.

The sealant used for the bonding comprises instant glue (such as 502 glue), epoxy resin bonding, anaerobic glue, UV glue (ultraviolet light curing type), hot melt glue, pressure sensitive adhesive, emulsion and the like.

In summary, the present disclosure provides a movement assembly 100 and a waterproof earphone 001, in which, through setting the glue storage groove 160 formed by a plurality of gaps with different directions at the connection positions of the upper case 122, the lower case 1224 and the movement support 142 of the movement assembly 100, the path of the glue storage groove 160 has a plurality of different directions, and when the path of the glue storage groove 160 of the waterproof earphone 001 is prolonged, the path direction of the glue storage groove 160 is changed, so that the glue storage groove 160 has a plurality of intersecting paths, thereby increasing the resistance when external water enters the movement assembly 100, and further improving the waterproof performance of the movement assembly 100.
