[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0032] Reference to "embodiment" in this application means that a specific feature, structure or characteristic described in conjunction with the embodiment may be included in at least one embodiment of this application. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.
[0033] The following is an exemplary description of the earphones according to the earphone embodiment.
[0034] The earphone 1 is an audio converter that can receive electrical signals from a media player or receiver and convert them into audible sound waves using a speaker 600 close to the ear. Figure 1 As shown, the earphone 1 may be an ear clip-on earphone for being inserted into the concha cavity of a user.
[0035] In some embodiments, Figure 1As shown, the earphone 1 may include a sound-emitting portion 100 for inserting into the concha cavity of the user (user) and an abutment portion 200 for abutting the back of the ear of the user. The earphone 1 may also include a connecting portion 300, which is used to connect to the sound-emitting portion 100 and the abutment portion 200. The connecting portion 300 can bypass the user's auricle, and the sound-emitting portion 100 and the abutment portion 200 form a clamping state on both sides of the user's auricle. The sound-emitting portion 100 can be a sound playing device, which is used to convert an electrical signal into an acoustic signal and play it to the wearer. The abutment portion 200 and the sound-emitting portion 100 can form a clamping state so that the entire earphone 1 is clamped and worn on the user's auricle. In some embodiments, a battery, a circuit board and other devices may be provided in the abutment portion 200. Of course, the abutment portion 200 may also be used without a battery, and the battery may be installed in the sound-emitting portion 100.
[0036] In some embodiments, Figure 2 as well as Figure 3 As shown, the earphone 1 may include a second housing 400 , a waterproof bracket 500 , a speaker 600 and a microphone 700 . The waterproof bracket 500 , the speaker 600 and the microphone 700 may all be disposed inside the second housing 400 .
[0037] In some embodiments, Figure 1 As shown in FIG. 2 , the earphone 1 further includes a first shell 800 and a connecting portion 300, wherein the connecting portion 300 connects the second shell 400 and the first shell 800. The second shell 400 may be a shell of the sound-emitting portion 100, and the first shell 800 may be a shell of the abutting portion 200. In the wearing state, the second shell 400 and the first shell 800 form a clamping state on both sides of the helix, and the second shell 400 may be located in the concha cavity of the human body.
[0038] In some embodiments, Figure 3 as well as Figure 4 As shown, the second shell 400 can be used to form a containing cavity 410 and is provided with a sound outlet hole 430 , a pressure relief hole 490 and a sound inlet hole 420 .
[0039] Alternatively, if Figure 2 as well as Figure 5 As shown, the connecting portion 300 has a symmetry plane DE arranged along the length direction of the connecting portion 300, and the sound outlet hole 430 and the sound inlet hole 420 are arranged symmetrically with respect to the symmetry plane DE. By arranging the sound outlet hole 430 and the sound inlet hole 420 which are arranged symmetrically with respect to the symmetry plane DE, the earphone 1 can be made suitable for both the left ear and the right ear while improving the aesthetics of the earphone 1, thereby effectively improving the adaptability of the earphone 1.
[0040] Furthermore, if Figure 3 as well as Figure 4As shown, the waterproof bracket 500 can be arranged inside the second shell 400, and the waterproof bracket 500 can include a partition plate 510. The outer edge of the partition plate 510 can be sealed and connected to the second shell 400, thereby dividing the accommodating chamber 410 into a first sub-accommodating chamber 411 and a second sub-accommodating chamber 412. The first sub-accommodating chamber 411 is connected to the outside of the second shell 400 through the sound outlet hole 430 and the pressure relief hole 490, and the second sub-accommodating chamber 412 is connected to the outside of the second shell 400 through the sound input hole 420.
[0041] Specifically, the speaker 600 may be disposed in the first sub-accommodation cavity 411. The sound emitted by the speaker 600 is transmitted to the outside of the second housing 400 through the sound outlet 430 and the pressure relief hole 490. The microphone 700 may be disposed in the second sub-accommodation cavity 412, and collects the external sound of the second housing 400 through the sound inlet 420.
[0042] By setting a waterproof bracket 500, the accommodating cavity 410 is divided into two non-connected cavities, and the speaker 600 and the microphone 700 are set in different cavities, and the pressure relief hole 490 and the sound input hole 420 are correspondingly set to be connected to different cavities, so that the pressure relief hole 490 and the microphone 700 can be separated, so that it is not easy for external moisture to enter the interior of the earphone 1 through the pressure relief hole 490 and further corrode and damage the microphone 700, thereby protecting the circuit of the microphone 700 and other components in the second sub-accommodating cavity 412 from corrosion, and can slow down the damage speed of the microphone 700, thereby improving the stability and service life of the microphone 700, and then improving the stability and service life of the earphone 1.
[0043] In some embodiments, Figure 3 as well as Figure 4 As shown, the second housing 400 may include a main body 440 and a transition portion 450. The transition portion 450 may connect the connection portion 300 and the main body 440, and may be arranged in a reduced shape in a direction close to the connection portion 300. The main body 440 may cooperate with the partition plate 510 to form a first sub-accommodation cavity 411, and the transition portion 450 may cooperate with the partition plate 510 to form a second sub-accommodation cavity 412.
[0044] The transition portion 450 is arranged to gradually decrease in the direction close to the connection portion 300, which can save space in the sound-emitting portion 100 and improve the aesthetics of the earphone 1. The microphone 700 is arranged in the second sub-accommodation cavity 412 formed by the transition portion 450 and the partition plate 510, which can also improve the space utilization of the earphone 1.
[0045] Optionally, the sound-emitting portion 100 may be provided with a wire channel 310, which may communicate with the internal space of the connecting portion 300, and the sound-emitting portion 100 may also be provided with a connecting hole 320, which may connect the wire channel 310 with the second sub-accommodating cavity 412. The microphone 700 placed in the second sub-accommodating cavity 412 may be connected to the abutting portion 200 through a wire (not shown), and the wire may pass through the connecting hole 320 and the wire channel 310 into the interior of the connecting portion 300 to be arranged in the connecting portion 300, thereby connecting to the abutting portion 200 through the connecting portion 300.
[0046] Therefore, the waterproof bracket 500 is provided to separate the pressure relief hole 490 from the second sub-accommodation chamber 412, and it is also difficult for external moisture to enter the second sub-accommodation chamber 412 from the pressure relief hole 490 and further enter the connecting hole 310 and the wire channel 310, thereby further protecting the wire and the interior of the connecting part 300 from corrosion. In addition, the microphone 700 can further block the sound inlet hole 420, and it is also difficult for external moisture to enter the second sub-accommodation chamber 412 from the sound inlet hole 420 and further enter the connecting hole 310 and the wire channel 310, thereby further protecting the wire and the connecting part 300, thereby improving the service life and stability of the earphone 1.
[0047] In some embodiments, Figure 4 as well as Figure 5 As shown, the second shell 400 may include a first sub-shell 460 and a second sub-shell 470. The first sub-shell 460 and the second sub-shell 470 may cooperate with each other to form a accommodating cavity 410. The first sub-shell 460 may form a transition portion 450 and a part of the main body 440. The second sub-shell 470 may form another part of the main body 440. The sound inlet 420 may be located on the first sub-shell 460, and the sound outlet 430 may be located on the second sub-shell 470.
[0048] Such a configuration can facilitate the assembly of the microphone 700, the waterproof bracket 500 and the speaker 600 into the second housing 400. For example, in the specific assembly process of the earphone 1, the microphone 700 can be first installed on the first sub-housing 460 at the position corresponding to the sound inlet 420, and then the waterproof bracket 500 and the speaker 600 can be assembled into the second sub-housing 470, and the first sub-housing 460 and the second sub-housing 470 are assembled to form the sound-emitting part 100. Therefore, the second housing 400 is configured in the form of two housings covering each other, which can reduce the assembly difficulty of the earphone 1 and facilitate the installation and disassembly process of the earphone 1.
[0049] In some embodiments, Figure 3As shown, the earphone 1 may include a circuit board 900 provided with a communication hole 910, the circuit board 900 may be arranged in the second sub-accommodation cavity 412, and is arranged in close contact with the inner wall surface of the second housing 400, the communication hole 910 may be connected to the sound inlet hole 420, and the microphone 700 is arranged on the side of the circuit board 900 away from the sound inlet hole 420, and the microphone 700 may collect external sound through the communication hole 910 and the sound inlet hole 420. The circuit board 900 may be connected to the microphone 700, and the microphone 700 may convert the external sound into an electrical signal after collecting the external sound, and transmit the electrical signal to the circuit board 900.
[0050] like Figure 3 As shown, the spacer 510 can be further configured to support the microphone 700 in the direction toward the circuit board 900. Therefore, the spacer 510 can further support the circuit board 900 by supporting the microphone 700, so that the circuit board 900 can be pressed against the inner wall surface of the second shell 400, so that the microphone 700 and the circuit board 900 can be further fixed to reduce the displacement of the microphone 700 and the circuit board 900, thereby enhancing the structural stability of the earphone 1. In addition, by supporting the first microphone 700 to press the circuit board 900, the spacer 510 can also strengthen the blocking of the sound inlet 420 by the circuit board 900, so that impurities such as dust and water droplets from the outside are not easy to enter the second sub-accommodation cavity 412 through the sound inlet 420, thereby protecting the circuit board 900 and the internal circuit of the microphone 700 from corrosion.
[0051] Optionally, the circuit board 900 can be directly attached to the inner wall surface of the second shell 400. In other embodiments, the circuit board 900 can also be indirectly attached to the inner wall surface of the second shell 400 through a sealing ring (not shown). Specifically, the sealing ring can be arranged in the inner wall surface of the second shell 400 in the circumference of the sound inlet 420, and the circuit board 900 can press the side of the sealing ring facing away from the inner wall surface of the second shell 400. The addition of the sealing ring can reduce the gap between the circuit board 900 and the second shell 400, thereby preventing external impurities such as dust and water droplets from entering the second sub-accommodation cavity 412 through the sound inlet 420 and the gap between the circuit board 900 and the second shell 400, thereby protecting the circuit board 900 and the internal circuit of the microphone 700 from corrosion.
[0052] In some embodiments, Figure 3As shown, the inner wall surface of the second housing 400 may be provided with an annular table surface 480 facing the first sub-accommodating cavity 411, and the edge of the spacer plate 510 is supported and fixed on the annular table surface 480. The use of the annular table surface 480 to correspond to the installation of the spacer plate 510 can not only facilitate the positioning and installation of the spacer plate 510 and reduce the difficulty of assembling the earphone 1, but also reduce the displacement of the spacer plate 510, thereby improving the structural stability and tightness of the ear clip.
[0053] In some embodiments, Figures 3 to 5 As shown, the surface of the partition plate 510 facing the speaker 600 can at least partially fit with the surface of the speaker 600 facing the partition plate 510. In this way, the shape of the partition plate 510 can be adapted to the shape of the speaker 600 facing the partition plate 510, so that the partition plate 510 can be closer to the speaker 600, thereby saving space inside the accommodating cavity 410 and reducing the size of the earphone 1.
[0054] For example, in some embodiments, Figure 4 as well as Figure 5 As shown, the speaker 600 may include a basin frame 610 , the radial projection of the basin frame 610 along the speaker 600 at least partially overlaps with the partition plate 510 , and the area of the partition plate 510 close to the basin frame 610 is arranged in an arc shape protruding toward the second sub-accommodating cavity 412 .
[0055] Specifically, the projection of the speaker 600 in its axial direction can present an approximately circular pattern. Therefore, the area of the partition plate 510 close to the basin frame 610 is arranged in an arc shape protruding toward the second sub-accommodating cavity 412, so that the area of the partition plate 510 close to the basin frame 610 can be fitted with the basin frame 610, so that the partition plate 510 can be closer to the speaker 600, thereby reducing the space occupied by the partition plate 510 and saving space inside the accommodating cavity 410.
[0056] Alternatively, if Figure 3 as well as Figure 5 As shown, the speaker 600 may include two speakers 620. Each speaker 620 includes a diaphragm (not shown). The two speakers 620 may be assembled and matched with each other along the axial direction (i.e., the vertical direction of the symmetry plane DE) to form a first acoustic cavity 621 between the two speakers 620. The speaker 600 may cooperate with the second shell 400 to form a second acoustic cavity 622 isolated from the first acoustic cavity 621 between the sound-emitting component and the second shell 400. Therefore, the speaker 600 may cooperate with the second shell 400 to separate the first sub-accommodating cavity 411 into a first acoustic cavity 621 and a second acoustic cavity 622. In other words, the speaker 600, the second shell 400 and the partition plate 510 together form the second acoustic cavity 622.
[0057] The first acoustic cavity 621 is connected to the sound outlet 430. The sound generated by one side of the diaphragm of the two speakers 620 is output through the first acoustic cavity 621 and the sound outlet 430. Figure 3 As shown, the second housing 400 is provided with a pressure relief hole 490, which is connected to the first sub-accommodation cavity 411. Optionally, the pressure relief hole 490 can be connected to the second acoustic cavity 622, and the sound generated by the other side of the diaphragms of the two speakers 620 is output through the second acoustic cavity 622 and the pressure relief hole 490.
[0058] Since the second acoustic cavity 622 and the pressure relief hole 490 are connected, air can flow freely between the second acoustic cavity 622 and the outside, thereby preventing pressure accumulation in the speaker 600 and causing changes in the sound quality of the speaker 600. Therefore, the space of the second acoustic cavity 622 will also affect the change in the sound quality of the speaker 600. The provision of the partition plate 510 can reduce the space of the second acoustic cavity 622, thereby reducing excessive air staying in the second acoustic cavity 622, so that the high-frequency peak of the sound wave emitted by the speaker 600 can be moved backward to improve the sound quality of the earphone 1.
[0059] In some embodiments, Figures 4 to 7 As shown, the waterproof bracket 500 may include a limiting portion 520 connected to the spacer 510, and the limiting portion 520 may extend toward the first sub-accommodating cavity 411, and the limiting portion 520 may be used to limit the speaker 600. Specifically, the limiting portion 520 may be fixed to the speaker 600, so that the spacer 510 and the speaker 600 are fixed to each other, and thus the spacer 510 can not only separate the speaker 600 from the microphone 700, but also further limit the microphone 700 and the speaker 600, so as to prevent the speaker 600 from shifting as much as possible, so that the internal structure of the earphone 1 is more compact and stable.
[0060] Alternatively, if Figure 5 As shown, a groove 611 may be provided on the basin frame 610. The limiting portion 520 may be embedded in the groove 611 and used to limit the rotation of the speaker 600 around the axial direction of the speaker 600. In other words, in the axial and radial directions of the speaker 600, the limiting portion 520 and a portion of the projection of the basin frame 610 have an overlapping portion. Therefore, the setting of embedding the limiting portion 520 in the groove 611 of the basin frame 610 can not only strengthen the axial limitation of the speaker 600, but also reduce the space occupied by the limiting portion 520, thereby saving the internal space of the accommodating cavity 410 and reducing the size of the earphone 1.
[0061] In some embodiments, Figure 5As shown, the number of the limiting parts 520 and the grooves 611 can be two groups, and they are respectively arranged on the two sides of the basin frame 610 that are arranged opposite to each other along the axial direction of the speaker 600. The two limiting parts 520 are arranged to radially limit the two sides of the speaker 600 that are arranged opposite to each other along the axial direction, which can enhance the limiting effect on the speaker 600 and limit the rotation of the speaker 600 around its axial direction and the movement along its axial direction.
[0062] In some embodiments, Figure 3 as well as Figure 4 As shown, the second housing 400 may be provided with a pressure relief hole 490, and the pressure relief hole 490 may be connected to the first sub-accommodation cavity 411. The earphone 1 may be provided with an isolation net 1000 on the side of the pressure relief hole 490 facing the first sub-accommodation cavity 411. Figure 4 , Figure 6 as well as Figure 7 As shown, the waterproof bracket 500 may further include a pressing portion 530 connected to the partition plate 510 , and the pressing portion 530 presses the isolation net 1000 onto the inner wall surface of the second shell 400 .
[0063] The isolation net 1000 is used to isolate dust particles and water droplets in the air, so that dust particles and water droplets in the air are not easy to enter the first sub-accommodating cavity 411, thereby corroding or damaging the speaker 600. For example, the isolation net 1000 can be an isolation cotton sheet, a gauze net, etc.
[0064] Moreover, the isolation net 1000 is pressed by the pressing portion 530 connected to the partition plate 510, which not only facilitates the positioning and assembly of the isolation net 1000, but also can further stabilize the isolation net 1000 on the inner wall surface of the second shell 400. Moreover, when the portion of the isolation net 1000 corresponding to the pressure relief hole 490 is subjected to pressure applied from the outside toward the accommodating cavity 410, the pressing portion 530 can support the isolation net 1000, thereby reducing the isolation net 1000 from loosening or falling under the action of external force, and can enhance the structural stability of the earphone 1.
[0065] In some embodiments, Figure 6 As shown, the pressing portion 530 may have an annular pressing surface 531, the shape of which matches the shape of the inner wall surface of the outer periphery of the pressure relief hole 490, so as to press and fix the isolation net 1000 on the inner wall surface along the circumference of the pressure relief hole 490. Specifically, the shape of the isolation net 1000 may match the shape of the pressing portion 530, and therefore, the provision of the annular pressing surface 531 may improve the pressing effect of the pressing portion 530, so as to firmly press the isolation net 1000 against the inner wall surface of the second shell 400 in the circumference of the pressure relief hole 490.
[0066] Optionally, the shapes of the pressing portion 530 and the pressure relief hole 490 can be adapted to the shape of the speaker 600 facing the pressure relief hole 490, and the side of the pressing portion 530 facing away from the isolation net 1000 can be partially abutted against the speaker 600, so that the speaker 600 can also further support the pressing portion 530 to further support the pressing isolation net 1000. Such a setting can further make the internal structure of the earphone 1 more compact and stable, and can also save the internal space of the accommodating cavity 410, so that the earphone 1 has a smaller size.
[0067] In some embodiments, Figure 6 as well as Figure 7 As shown, the partition plate 510 may be provided with a lead channel 511, which may penetrate the partition plate 510 to connect the first sub-accommodating cavity 411 and the second sub-accommodating cavity 412, and the lead channel 511 is used to accommodate a connecting lead (not shown) connecting the circuit board 900 and the speaker 600. The circuit board 900 and the speaker 600 transmit signals through the connecting lead.
[0068] Optionally, after the connecting lead passes through the lead channel 511, the lead channel 511 can be further sealed with glue to fix the connecting lead in the lead channel 511, and to prevent moisture in the first sub-containing cavity 411 from easily entering the second sub-containing cavity 412 through the lead channel 511, thereby achieving a sealed connection between the partition plate 510 and the second shell 400.
[0069] Optionally, the number of the lead channels 511 may be two, and the two lead channels 511 may respectively correspond to the two speakers 620 of the speaker 600 , and the two lead channels 511 are respectively used to accommodate connecting leads between the two speakers 620 and the circuit board 900 .
[0070] The arrangement of the lead wire channel 511 penetrating the partition plate 510 can simplify the wiring inside the earphone 1 to save space inside the earphone 1, and can also further position the connecting lead wires, thereby facilitating the assembly of the connecting lead wires.

The microphone assembly 1200 may be fixed on the cover plate 1100, and is located in the housing cavity 810 and corresponds to the first window 820, and the microphone assembly 1200 further collects the external sound of the first shell 800 through the sound inlet hole 420.
[0074] By providing the first window 820 on the first housing 800 and providing the microphone assembly 1200 on the cover plate 1100 covering the first window 820, when assembling the earphone 1, the microphone assembly 1200 can be first installed on the cover plate 1100, and then the cover plate 1100 is installed on the first window 820 and connected to the second housing 400, so as to facilitate the installation of the microphone assembly 1200 and reduce the difficulty of assembling the earphone 1. In addition, the sound inlet hole 420 is provided on the cover plate 1100 corresponding to the microphone assembly 1200, which can facilitate the positioning of the microphone assembly 1200, the assembly of the microphone assembly 1200, and the sound reception effect of the microphone assembly 1200 can be improved.
[0075] Alternatively, if Fig.10 As shown, the earphone 1 may further include a battery 1300 . The battery 1300 may be disposed in the accommodating cavity 810 . The battery 1300 may be connected to the microphone assembly 1200 via the connecting portion 300 to supply power to the microphone assembly 1200 .
[0076] In some embodiments, Fig. 9 as well as Fig.10 As shown, the earphone 1 may further include a connecting portion 300, the first shell 800 may include a main body area 830 and a transition area 840, the transition area 840 may connect the connecting portion 300 and the main body area 830, and may be arranged in a tapered shape in the direction close to the connecting portion 300, the first window 820 may be arranged on the transition area 840, and the microphone assembly 1200 may be arranged in the transition area 840.
[0077] Specifically, one end of the connecting portion 300 can be connected to the transition portion 450 of the second shell 400, and the other end can be connected to the transition zone 840 of the first shell 800, and the transition zone 840 is gradually reduced in the direction close to the connecting portion 300, which can save space for the abutting portion 200 and improve the aesthetics of the earphone 1. The first opening 820 and the microphone assembly 1200 are arranged on the transition zone 840, which can also improve the space utilization of the earphone 1, further save space in the first shell 800, and thus make the size of the abutting portion 200 smaller.
[0078] In some embodiments, Fig.10 As shown, the first housing 800 may include an upper housing 850 and a lower housing 860, the upper housing 850 and the lower housing 860 may cooperate with each other to form a receiving chamber 810, the upper housing 850 is a part of the transition area 840 and the main body area 830, and the lower housing 860 is another part of the main body area 830. Specifically, the first window 820 may be opened in the upper housing 850, and the cover plate 1100 and the microphone assembly 1200 are both disposed on the upper housing 850.
[0079] The arrangement of dividing the first shell 800 into two shells can facilitate the installation of the battery 1300 and other components in the first shell 800 , so as to facilitate the installation and disassembly of the earphone 1 and reduce the difficulty of assembling the earphone 1 .
[0080] In some embodiments, Fig. 9 as well as Fig.10 As shown, the earphone 1 may further include a flexible connector 1400 and a circuit board component 1500 disposed in the accommodating cavity 810 , and the flexible connector 1400 electrically connects the microphone assembly 1200 and the circuit board component 1500 .

[0082] Optionally, the flexible connector 1400 may be arranged in a long strip shape, the microphone assembly 1200 is arranged to connect one end of the flexible connector 1400, and the circuit board component 1500 may be connected to the other end of the flexible connector 1400. Of course, in other embodiments, the flexible connector 1400 may also be in other shapes such as a circle or an ellipse.
[0083] The length of the flexible connector 1400 can be set to allow the microphone assembly 1200 to be moved out of the accommodating cavity 810 through the first window 820 while the flexible connector 1400 is respectively connected to the microphone assembly 1200 and the circuit board assembly 1500. Specifically, the shape and size of the flexible connector 1400 can be set to match the shape of the first window 820, and the end of the flexible connector 1400 connected to the microphone assembly 1200 can be moved out of the accommodating cavity 810 through the first window 820.
[0084] Specifically, during the assembly of the earphone 1, the flexible connector 1400 can be connected to the circuit board 1500 first, and then the circuit board 1500 can be installed in the second housing 400, and then the end of the flexible connector 1400 away from the circuit board 1500 can be pulled out from the first window 820. The microphone assembly 1200 is installed on the cover 1100, and the microphone assembly 1200 is further connected to one end of the flexible connector 1400, so that the cover 1100 and the microphone assembly 1200 are arranged on one end of the flexible connector 1400, and then the cover 1100 and the microphone assembly 1200 are pressed and installed in the first window 820 to press the flexible connector 1400 back into the accommodating cavity 810, thereby completing the connection process between the microphone assembly 1200 and the flexible connector 1400 and the process of fixing the microphone assembly 1200 to the second housing 400.
[0085] Alternatively, the microphone assembly 1200 may be first installed and connected to one end of the flexible connector 1400, and then the microphone assembly 1200 is moved out of the accommodating cavity 810 through the first window 820 following one end of the flexible connector 1400, and then the microphone assembly 1200 is installed on the cover plate 1100, and then the cover plate 1100 and the microphone assembly 1200 are pressed and installed in the first window 820 to press the flexible connector 1400 back into the accommodating cavity 810, thereby completing the installation process of the microphone assembly 1200.
[0086] Therefore, the provision of the first window 820 and the flexible connector 1400 can facilitate the assembly of the microphone assembly 1200 , simplify the assembly process of the microphone assembly 1200 , and reduce the difficulty of assembling the earphone 1 .
[0087] In some embodiments, Fig.11 as well as Fig.12 As shown, the upper shell 850 may further include a hard shell 851 and an elastic coating 852 covering at least a portion of the hard shell 851, the hard shell 851 may have an exposed area 8511 exposed from the elastic coating 852, the first window 820 may be arranged on the exposed area 8511, and the cover 1100 may be supported on the exposed area 8511.
[0088] Specifically, the elastic coating 852 is provided with a through hole 8521 corresponding to the exposed area 8511, and the through hole 8521 is connected to the outside and the first window 820. In the thickness direction of the cover plate 1100, the projected area of the through hole 8521 is larger than the projected area of the first window 820, so that the elastic coating 852 and the hard shell 851 form a step surface, that is, the hard shell 851 is formed in the exposed area 8511 exposed in the through hole 8521. A part of the cover plate 1100 can be inserted into the first window 820, and the other part can be supported on the exposed area 8511, and the part of the cover plate 1100 facing the hole wall of the through hole 8521 can circumferentially abut the elastic coating 852. Among them, in the thickness direction of the cover plate 1100, Fig.11 Indicated by the arrow in F.
[0089] By setting the exposed area 8511 of the hard shell 851, the positioning and installation of the cover 1100 can be facilitated, so that the cover 1100 is not easily displaced, and the connection firmness between the cover 1100 and the second shell 400 is improved, thereby making the structure of the earphone 1 more compact and stable.
[0090] Alternatively, if Fig.11 as well as Fig.12 As shown, the outer surface of the cover plate 1100 can smoothly transition with the outer surface of the elastic coating 852. Specifically, the outer surface of the cover plate 1100 facing away from the first window 820 and the outer surface of the elastic coating 852 facing away from the hard shell 851 smoothly transition, so that the abutting portion 200 forms a smooth and flat surface. Such a setting can make the surface of the earphone 1 flat and improve the aesthetics of the earphone 1. The setting of the elastic coating 852 can not only facilitate the installation of the cover plate 1100 on the second shell 400, but also improve the wearing comfort of the earphone 1.
[0091] In some embodiments, Fig. 9 , Fig.11 as well as Fig.12 As shown, the cover plate 1100 may include a cover plate body 1110 and an insertion portion 1120 connected to the cover plate body 1110, and the insertion portion 1120 may be inserted into the first window 820. The cover plate body 1110 may be supported at the periphery of the first window 820 and cover the first window 820, and the sound inlet 420 may be provided on the cover plate body 1110.
[0092] Specifically, one end of the insertion portion 1120 is connected to the cover body 1110, and the other end is inserted into the first window 820, and its extension direction is perpendicular to the cover body main board. The cover body 1110 covers the first window 820 and the exposed area 8511 of the hard shell 851. By setting the shape of the cover 1100 in this way, the shape of the cover 1100 can correspond to the shape of the first window 820 and the exposed area 8511. When the cover 1100 is assembled on the second shell 400, the insertion portion 1120 can correspond to the first window 820 and can be directly inserted into the first window 820, which is convenient for positioning and installation of the cover 1100, thereby reducing the difficulty of assembling the cover 1100.
[0093] In some embodiments, Fig. 9 , Fig.11 as well as Fig.12 As shown, a receiving groove 1121 may be provided on the side of the insertion portion 1120 facing the receiving cavity 810, and a ring-shaped step surface 1122 may be further provided at the bottom of the receiving groove 1121. The ring-shaped step surface 1122 may be surrounded by a connecting groove 1123, and the connecting groove 1123 connects the receiving groove 1121 and the sound inlet 420. The microphone assembly 1200 is at least partially disposed in the receiving groove 1121.
[0094] Specifically, part of the bottom of the microphone assembly 1200 can abut against the annular step surface 1122, and the circumference of the microphone assembly 1200 can abut against the insertion portion 1120. Such a configuration can facilitate the placement and installation of the microphone assembly 1200 in the accommodating groove 1121, so as to facilitate the positioning and installation of the microphone 700.
[0095] In some embodiments, Fig.12 As shown, the microphone assembly 1200 may include a microphone 700 and a support plate 1210, the support plate 1210 may be provided with a second window 1211, the support plate 1210 may be supported on the annular step surface 1122, and the second window 1211 and the connecting groove 1123 may overlap each other in the thickness direction of the cover plate 1100, and the microphone 700 may be provided on a side of the support plate 1210 away from the connecting groove 1123. Specifically, the second window 1211 is connected to the connecting groove 1123, and the microphone 700 may collect external sounds through the second window 1211, the connecting groove 1123 and the sound receiving hole in sequence.
[0096] By setting the microphone 700 on the support plate 1210 and setting the support plate 1210 on the cover plate 1100, the microphone 700 can be not directly connected to the cover plate 1100, which facilitates the installation, disassembly and maintenance of the microphone 700 and also makes the microphone 700 less susceptible to damage during the installation and disassembly process, thereby protecting the microphone 700.
[0097] In some embodiments, Fig.12 As shown, the earphone 1 may further include an isolation mesh 1600, and the support plate 1210 may press and fix the isolation mesh 1600 on the annular step surface 1122, and the isolation mesh 1600 further covers the connecting groove 1123. The isolation mesh 1600 is used to filter impurities such as dust and water droplets in the air to prevent dust and water droplets from entering the second window 1211 and entering the interior of the microphone 700, thereby protecting the microphone 700, so that the internal circuit of the microphone 700 is not easily corroded by dust and water droplets in the air. In other embodiments, the isolation mesh 1600 may also be arranged in the connecting groove 1123 to cover the connecting groove 1123 and the sound inlet 420, and the support plate 1210 may also abut against the annular step surface 1122 to limit the isolation mesh 1600 in the connecting groove 1123.
[0098] Optionally, the isolation mesh 1600 may be a steel mesh, or other mesh materials such as a gauze mesh.
[0099] In some embodiments, the earphone 1 may further include a foam sheet (not shown), which may be pressed on the annular step surface 1122 by the support plate 1210 together with the isolation mesh 1600. Alternatively, the foam sheet may be pressed in the communication groove 1123 by the isolation mesh 1600.
[0100] The foam sheet can also be used to filter dust, water droplets and other impurities in the air. The addition of the foam sheet can enhance the filtering effect on the air, further blocking dust, water droplets and other impurities from the outside from entering the second window 1211 and entering the microphone 700 to corrode the microphone 700, thereby further protecting the microphone 700.
[0101] In some embodiments, Fig.12 As shown, the number of the sound inlet holes 420 can be two, the sound inlet ends of the two sound inlet holes 420 are spaced apart from each other, and the sound outlet ends of the two sound inlet holes 420 are connected to each other via the connecting groove 1123. Specifically, one end of the two sound inlet holes 420 connected to the outside is the sound inlet end, and one end of the two sound inlet holes 420 connected to the connecting groove 1123 is the sound outlet end.
[0102] A connecting groove 1123 is provided to connect the two sound inlet holes 420 , so that air can flow between the two sound inlet holes 420 and the connecting groove 1123 , thereby reducing wind noise and improving the sound collection effect of the microphone 700 .
[0103] In some embodiments, Figure 8As shown, the connecting portion 300 may have a symmetry plane DE arranged along the length direction of the connecting portion 300, and the sound inlet holes 420 are symmetrically arranged with respect to the symmetry plane DE. Specifically, the two sound inlet holes 420 may be symmetrically arranged with respect to the symmetry plane DE. Such an arrangement can improve the aesthetics of the earphone 1 while making the earphone 1 suitable for both the left ear and the right ear, thereby effectively improving the adaptability of the earphone 1.
[0104] To sum up, the present application utilizes a waterproof bracket 500 to be disposed inside the first shell 400 and to separate the microphone 700 and the speaker 600 from the pressure relief hole 490, so that external moisture is not easy to enter the interior of the earphone 1 through the pressure relief hole 490 and corrode and damage the microphone 700, thereby protecting the microphone 700, slowing down the damage speed of the microphone 700, and improving the stability and service life of the earphone 1.
